Definitions

  • the invention relates to a device for comminuting various materials, in particular waste, the device having a comminution drum which is open at the top and has a horizontal drum base and a cylindrical drum casing, a comminution rotor rotatably mounted about the vertical drum axis with at least one attached to it in the comminution drum Comminution tool is provided, and the drum shell has at least one closable contaminant discharge opening with an opening height.
  • a crushing device in which an impact reactor is used to process components made of mixed plastics and other construction materials mixed with them, such as metal parts, glass, rubber, wood or fiber materials, and the components are crushed by an impact stress in the device.
  • the material is removed from the impact reactor via a material outlet flap that can be opened.
  • An adaptation to different material mixtures and material types is therefore not possible.
  • Another significant disadvantage of this known device is that the rotor and thus also the impact elements within the reactor space cannot be adjusted in height in order to achieve any desired adaptation to the material. Adjustment is only possible with the help of washers, which is extremely complex and in particular also leads to machine downtimes. There is no separate discharge for coarse material or solid contaminants that cannot be further shredded.
  • a device for comminuting objects having a container having a peripheral wall and a bottom and a receiving head provided in a lower region of the container, on which at least one striking tool is provided, which in the revolves around the bottom of the container.
  • At least a lower part of the peripheral wall and / or the bottom are of sieve-like design, so that the container is open to the surroundings at least there, a discharge shaft for discharging fine material being coupled to the sieve-like area of the bottom and / or the peripheral wall.
  • the grain sizes of the material to be shredded depend on the nature and mesh size of the sieve used.
  • the screen openings can be designed, for example, as slot openings or circular holes.
  • the edges of the screen openings act as baffles for the waste material to be shredded.
  • sieves or sieve coverings Materials that can be used as separation media and contain a large number of equally large sieve openings are generally referred to as sieves or sieve coverings.
  • the sieves described below are preferably made of metal and can be produced, for example, as perforated plates, wire mesh, metal grids or from metal bars.
  • the size of the screen openings is called the mesh size and defines the screen cut. In most countries, the size of the screen openings is defined in “mm” or “ ⁇ m", in the USA the specification in “mesh” (number of screen openings per square inch) is common. Particles that are too large are retained by the sieve and form the so-called sieve overflow or coarse material. Small particles pass through the sieve openings and form the so-called sieve passage, which is also known as fine material. Particles of approximately the same size as the size of the sieve openings are referred to as boundary particles.
  • a sieve can consist of one or more sieve layers lying one above the other, the sieve with the largest
  • the disclosed embodiment is at least that for solid impurities which are present in the waste material and which cannot be or only inadequately comminuted in the comminution device, no possibilities for discharge are provided. Due to the arrangement of sieve surfaces in the lower part of the peripheral wall and at the bottom of the container, solid contaminants are deposited precisely on the sieve surfaces during continuous operation of the shredding device and thus block the discharge shaft coupled to the sieve surfaces for discharging fine material, which is undesirable and what to regular maintenance interruptions to the operation of the device leads, since the separation performance of the shredding device decreases rapidly due to the contaminants accumulated in the base area.
  • the document DE 196 03 603 A1 describes a shredding device with a cylindrical housing, a lower wall section being designed as a closed grinding surface and an upper wall section being designed as a sieve.
  • a device for processing components made of mixed materials has become known.
  • a rotor with impact elements attached to it is provided in an impact reactor with a cylindrical jacket.
  • One or more discharge openings are arranged on the circumference of the casing in the area of the rotor, each of which is covered with slotted or perforated cover plates.
  • a disadvantage of this embodiment is at least that the ejection openings are spaced apart from each other in the axial direction from the impact reactor floor.
  • depressions are provided in the impact reactor floor in order to collect and deposit coarse material therein.
  • a further ejection opening which is covered with a slotted or perforated cover plate, can be provided in this lowered or recessed area of the impact reactor base.
  • This embodiment also has disadvantages, since the manufacture of an impact reactor base with depressions is complex and there is a risk of blockage of coarse material which has already been deposited in the depressions and is clamped by the impact edges of the impact elements.
  • the side parts are designed as tightly closing flaps without outlet openings - as an impurity flap or as a man flap. Undesired damage or blockages due to the accumulated impurities or the coarse material can thus not be avoided at least for the lower outlet openings of the grinding chamber casing reaching to the bottom of the grinding chamber.
  • the present invention therefore has as its object to avoid the disadvantages known from the prior art for shredding devices of the type mentioned at the outset, and to create a device which is suitable for continuously shredding various materials, in particular waste, and which are correspondingly robust is to process even higher proportions of solid contaminants in the waste material, which cannot or cannot be comminuted adequately, regardless of the separation performance of the comminution device.
  • the device having a comminution drum open at the top with a horizontal drum base and a cylindrical drum casing, and in the comminution drum a comminution rotor rotatably mounted about the vertical drum axis with at least one comminution tool attached to it is provided and the drum jacket has at least one closable contaminant discharge opening with an opening height, the at least one contaminant discharge opening in the drum jacket directly borders the drum base
  • the drum shell is formed from a dense wall material in its lower drum shell section, which extends from the drum bottom to the opening height of the impurity discharge opening, the drum shell having a permeable upper drum shell section directly next to the dense lower drum shell section, which at least in sections as a sieve shell permeable to fine material is formed with sieve openings.
  • the drum base and the lower drum shell section which by definition extends in the drum axis direction from the drum base to the opening height of the contaminant discharge opening, are advantageously formed from a dense wall material.
  • impurities can be collected and separated in this dense lower drum casing section, which impurities cannot or only inadequately be comminuted by the rotating comminution tools which are attached to the comminution rotor.
  • the at least one impurity discharge opening is located in the drum jacket at the same level as the horizontal, level drum base.
  • the at least one impurity discharge opening in the drum casing thus begins directly at the level of the drum base and extends with its opening height in the casing direction to the border between the dense lower drum casing section and that at least sectionally permeable upper drum casing section which is located directly adjacent to the opening height of the contaminant discharge opening and which is formed at least in sections as a sieve shell with sieve openings that is permeable to fine material.
  • the jacket height of the dense lower drum jacket section corresponds to the opening height of the at least one contaminant discharge opening. If a plurality of impurity discharge openings are arranged along the circumference of the drum shell, then these impurity discharge openings are either either all of the same size and each have the same opening height. Alternatively, the plurality of impurity discharge openings have different opening heights, the impurity discharge opening with the largest opening height in relation to the level of the drum base specifying the casing height of the dense lower drum casing section. In any case, all the discharge openings for contaminants begin at the same level with the drum base in order to eliminate the disadvantages of excessive discharge openings known from the prior art, which act like overflow weirs and which impede the unimpeded discharge of contaminants.
  • the impurities collected in the comminution drum do not therefore hinder the areas of the sieve jacket, since they are collected with dense walls in the lower drum jacket section lying underneath in the direction of the drum axis.
  • the lower drum casing section is advantageously completely closed or sealed. Unwanted damage or blockages of the screen openings due to the accumulated contaminants or coarse material are thus reliably avoided. Due to the flat drum base, damage to the shredding rotor or the shredding tools attached to it is also avoided.
  • Coarse material that can no longer be shredded is simply sanded by the rotating shredding tools over the dense, flat drum base or along the closed, dense walls of the lower drum shell section until it is level with the drum base through one or more open contaminant discharge openings is carried outside. Blocking, deformation or even damage to the comminuting rotor drive can thus be reliably avoided due to the inventive design of the comminuting device.
  • impurities can be discharged from the comminution drum, for example continuously or semi-continuously, during operation through the at least one closable discharge opening without the device having to be switched off.
  • a plurality of impurity discharge openings can also be provided, which are arranged, for example, at equal intervals from one another along the lower, dense drum casing section, each starting at the same level as the drum base. For example, metals, glass and minerals are removed as impurities that cannot be used.
  • the impurities are discharged from the comminution drum by means of centrifugal forces, frictional forces and / or momentum or displacement forces.
  • a separate drive to discharge the accumulated contaminants is not necessary.
  • the at least one contaminant discharge opening is expediently opened periodically in order to allow the removal of accumulated contaminants. In any case, fines are withdrawn continuously through the screen openings in the upper drum jacket section of the screen jacket.
  • the drum axis coincides with the rotor axis of the comminution rotor.
  • one or more impact chains can be attached to the comminution rotor as the comminution tool.
  • Several impact chains are preferably attached in a star shape to the comminution rotor, the impact chains at an attachment height or in different mounting heights can be attached in relation to the rotor axis.
  • Rigid shredding tools can also be used, which can be fastened to the shredding rotor in one or more fastening heights spaced apart from one another in the axial direction.
  • the upper drum casing section can be designed as a sieve casing along its entire circumference in a comminution device.
  • the preparation surface of the screen jacket extends along the entire circumference of 360 °, which leads to a particularly large screen area and the highest possible separation performance in relation to the possible throughput of fine material through the comminution device.
  • the screen jacket in the upper drum jacket section can be formed from at least two screen segments, preferably from at least two screen segments with different screen mesh sizes.
  • different fractions of fine material can advantageously be separated or the fine material can be classified.
  • the sieve mesh size denotes the size of the sieve openings and thus defines the sieve cut.
  • different screens and screen materials can be used within the scope of the invention, and the design and geometry of the screen openings are also not subject to any restrictions.
  • sieves or sieve segments can be produced as perforated plates, wire mesh, metal grids or from metal rods.
  • the screen openings can be designed, for example, as round holes with a defined hole diameter.
  • the screen openings can have, for example, oval, rectangular or square edges or can be structured as a fabric or grid.
  • the sieve openings are expediently approximately 5 mm to 100 mm in size, the selection of the sieve material used depending on the particular comminution task or the waste material to be comminuted.
  • each sieve segment with a different sieve mesh size is followed by a separate fine material discharge.
  • the individual sieve segments with different sieve mesh widths are separated from each other by separate fines or fines collection devices. Waste materials to be shredded can thus be separated into several grain size fractions comparable to a sieve cut, which can have advantages in the subsequent further processing.
  • the different screen segments can be arranged, for example, optionally offset from one another transversely to the circumferential direction, along the upper drum shell section. Individual sieve segments thus form individual circumferential sections of the upper drum casing section.
  • the different screen segments can also form individual height sections of the upper drum shell section one above the other in the circumferential direction of the upper drum shell section in the direction of the vertical drum axis.
  • a first screen segment is located in a strip-like manner with a first jacket height measured in the drum axis direction, adjacent to the dense lower drum jacket section, the first screen segment having a first screen mesh size.
  • Adjacent directly above this is a second sieve segment, which also extends along the entire circumference as a sieve jacket and forms a second sieve strip which, viewed in the direction of the drum axis, has a second jacket height.
  • Classification of the fine material is also advantageously possible in this embodiment. If the sieve segments are arranged alternately in the circumferential direction or alternatively transversely to the circumferential direction, a plurality of sieve segments, each with the same sieve mesh size, can expediently be coupled to one and the same fine material discharge.
  • a casing height of the lower, dense drum casing section measured in the drum axis direction can be particularly expediently from 2% to 50%, preferably from 3% to 30%, particularly preferably from 5% to 20%, of the total casing height of the drum casing of the comminution drum.
  • a comminution drum with a casing height of the drum casing, for example, of 100 cm would thus have a lower, dense drum casing section which, depending on the task, has a casing height of 2 cm to 50 cm, measured in the drum axis direction from the bottom of the comminution drum.
  • the design, fastening position and / or number of the shredding tools attached to the shredding rotor can advantageously also be adapted to the respective shredding task.
  • the attachment points of impact chains, which are attached as comminution tools to the comminution rotor can be varied in their attachment position in the axial direction of the rotor.
  • the at least one closable contaminant discharge opening with a downstream one can be particularly expedient Impurity discharge can be coupled, wherein at least one closure device is provided in the discharge of impurities, which acts on the discharge opening for contaminants.
  • contaminants pass through the one or more opened discharge openings into a downstream contaminant discharge, for example a discharge shaft, as soon as a closure device is opened.
  • the closure device can be arranged directly in the area of the contaminant discharge opening or else in the area of the contaminant discharge opening and in any case acts on the at least one contaminant discharge opening.
  • the at least one closure device can be designed, for example, as a slide or flap. If necessary, further locking devices can be provided in the contaminant discharge or discharge duct to prevent undesirable simultaneous leakage of fine material together with the coarse material or the contaminants when the discharge opening is open.
  • the impurity discharge opening can be coupled to a closure control for opening and closing the at least one closure device.
  • a closure control for opening and closing the at least one closure device.
  • different lock control programs can be implemented depending on the size reduction task.
  • the at least one closure device is opened and closed periodically in order to discharge accumulated contaminants semi-continuously.
  • the closure control naturally acts together on the plurality of closure devices.
  • a lock effect can be realized with a corresponding control, a closure device arranged downstream in the discharge of impurities only being opened when the first closure device or the closure device arranged upstream in the discharge direction is already closed again. This lock control prevents unwanted discharge of fine material, which can get into the contaminant discharge when the contaminant discharge opening is open.
  • the contaminant discharge opening can be closed with at least one contaminant slide.
  • An impurity valve has the advantage of being particularly robust and is therefore particularly well suited for the closure task of the impurity discharge opening.
  • the front-side slide plate of the interfering material slide is preferably designed such that in the closed position it is flush with the inside wall of the tight lower drum shell section in the, if possible without joints and gaps Shredding drum completes.
  • the impurity valve is also used to keep the discharge of contaminants free.
  • these are each equipped with an impurity slide as a closure device.
  • the contaminant pusher is particularly advantageously arranged to be horizontally displaceable.
  • a horizontally or horizontally arranged impurity slide which is therefore positioned at the same level as the horizontal drum base, offers the advantage that impurities can be removed from the side of the shredding drum without hindrance. Unwanted blocking of the contaminant discharge opening can thus be reliably prevented, which ensures continuous operation of the comminution device without regular downtimes due to maintenance work.
  • the closable contaminant discharge opening is particularly advantageously coupled to a sealing air blower for blowing sealing air through the opened contaminant discharge opening into the comminution drum.
  • Sealing air which enters the inside of the comminution drum against the direction of discharge of the coarse material or the impurities from the outside through the open impurity discharge opening, prevents the discharge of fine material, i.e. light, fine or already severely comminuted waste particles into the impurity discharge chute or at least significantly reduced.
  • a blower control for controlling the sealing air blower can be provided in a comminution device, the blower output of the sealing air blower being controllable in such a way that the blower output when the impurity discharge opening is open is increased compared to that when the discharge opening is closed.
  • a permanent air flow is generated by the sealing air blower, which prevents unwanted deposits in the area of the discharge chutes.
  • an air-permeable fabric or filter material in particular a fabric filter, which is arranged, for example, at the upper end of the impurity chute, this permanent air stream - after filter separation of possible fine particles - has emerged from the comminution device.
  • the air flow after the cleaning of fine material particles is fed back, for example, back into the interior of the drum or into one of the fine material discharge chutes. If the impurity discharge opening opens, the fan control increases the blower output accordingly, and a partial flow of the sealing air reaches the interior of the drum through the one or more impurity discharge openings. As a result, the undesired discharge of fine material or of coarse material that can be further ground, grinded into the discharge shaft is prevented as far as possible.
  • the comminution rotor can be particularly advantageously coupled to a drive unit comprising a drive motor, the drive unit being mounted separately from the comminution drum.
  • the driving forces, shocks or vibrations and torques of the comminution rotor together with the comminution tools attached to it are introduced into a support frame of the comminution device.
  • the drive unit together with the drive motor is mounted separately from the shredding drum in terms of force.
  • the drive unit is preferably fastened on a separate support frame with corresponding vibration dampers.
  • Vibrations of the comminution drum are therefore advantageously not transmitted to the drive unit, as a result of which the maintenance intervals and downtimes of the comminution device can be extended accordingly.
  • a lighter and less expensive construction of the comminution device is possible than is often possible in conventional comminution machines in which the forces are introduced into the comminution drum.
  • a suction device for extracting fine material can be provided.

  • Falling feed material for example waste material 100 to be comminuted, passes through the feed chute 11 into the comminution drum 20, which is open at the top, and is thereby gripped by the rotating impact chains 45 and crushed by mutual collision and by the sieve edges of the sieve jacket 26. Furthermore, the waste material 100 to be shredded is rapidly shredded due to the acting centrifugal forces, frictional forces and momentum or displacement forces between the internal rotating impact chains 45 and the external static drum base 21 and the drum casing 23. Correspondingly comminuted material is - depending on the screen size of the screen jacket 26 - transported by the centrifugal forces and the fan effect of the rotating impact chains 45 through the screen jacket 26 to the outside in the fine material space 280 and from there by gravity to the fine material discharge 280.
  • the fine material 280 arrives for further processing via a speed-controlled fine material conveyor belt 29 or speed-controlled screw conveyors.
  • a suction device which acts on the fine material discharge space or discharge shaft 28 and pressurizes it in order to further facilitate and accelerate the separation of fine material 280 through the sieve openings 27 of the sieve jacket 26.
  • the separation performance of the shredding device 1 can be increased further.
  • the deposited coarse material is entrained by the comminuting rotor 40 and moved along the lower drum shell section 24 by the rotating comminution tools 45 until the closure device 31, here the impurity slide 32, is opened to the outside in the direction of arrow 320 and the contaminant discharge opening 30 is opened .
  • the impurity slide 32 releases the impurity discharge chute 33, and impurities 330 can get out into the impurity discharge chute 33.
  • the contaminant slide 31 advantageously releases the entire opening height 300 of the contaminant discharge opening 30.
  • the closure device 31 After separation of the discharged contaminants 330, the closure device 31 is closed again in the direction of the arrow 320 and the lower, empty drum space is again available for collecting contaminants.
  • the interfering substance slide 32 is expediently opened and closed periodically by the closure control 310 in order to empty the lower drum space at regular time intervals. Apart from times or operating states in which the impurity valve 32 is temporarily open during operation, the rest of the lower drum space with the impurity valve 32 closed is from the drum base 21 to the jacket height 240 of the lower, sealed drum jacket section 24 through a tight, closed wall or floor material limited.
  • the end face of the impurity slide 32 is advantageously adapted to the contour of the lower drum casing section 24 and is made of the same robust, dense wall material as the lower drum casing section 24.
  • a plurality of impurity discharge openings 30 can also be provided in a comminution device 1, which are arranged, for example, at uniform intervals in the circumferential direction along the lower drum shell section 24.
  • the impurity discharge openings 30 are each provided at the same level as the horizontal drum base 21.
  • Fig. 3 shows in a side view the in Fig. 2 Illustrated shredding device 1 together with outer housing 10, drive unit 60 and further peripheral devices.
  • a sealing air blower 50 is provided here. Sealing air 500, which is generated by the sealing air blower 50, moves in the direction of arrow 500 against the discharge direction of the contaminants 330 in the direction of the closure device 31, which is implemented here as a slide valve 32.
  • the impurity discharge chute 33 is expediently also closed further below the sealing air supply 500, for example with a further slide.
  • a contaminant lock with two closure devices arranged one after the other in the flow direction of the contaminants 330 is formed within the contaminant discharge chute 33.
  • the downstream slide or the downstream closure device only opens when the upstream closure device is closed again.
  • the impurity discharge chute is equipped with a protected, air-permeable fabric above the impurity slide 32 in order to prevent fines deposits.
  • a constant air flow is generated from the impurity discharge shaft through the tissue by means of a sealing air blower 50.
  • the blower output can be controlled by means of a blower control 510 of the sealing air blower 50 in such a way that the blower output is increased compared to that when the discharge opening is open when the impurity discharge opening 30 is open.
  • a majority of the partial flow of the air is blown through the impurity discharge opening 30 into the comminution drum 20 when the blower output is increased. This is to reduce the discharge of light materials or fine material 280 into the contaminant discharge chute.
  • a drive unit 60 for driving the comminution rotor 40 is also shown.
  • the drive unit 60 comprises a drive motor 61 with a belt drive 62, which one forms a non-positive connection between the drive motor 61 and the drive shaft 41 of the comminution rotor 40.
  • the drive unit 60 is advantageously mounted separately from the comminution drum 20 or decoupled in terms of force.
  • Corresponding vibration dampers 70 which are arranged between the support frame 80, on which the drive unit 60 is mounted, and the other supporting components of the comminution device 1 prevent in a manner known per se that oscillations and vibrations of the comminution drum 20 can act mechanically on the drive unit 60 .
  • Fig. 3 Above the feed area of the waste material 100, the drum hood 13 can be seen, which is provided with a manhole and can be removed for maintenance purposes.
  • a suction device 12 is also provided above the fine material conveyor belt and the interfering substance conveyor belt 35 shown in the foreground in order to prevent the undesirable dust escape outside the comminution device 1 as far as possible.
  • the outer housing 10 is designed to be removable for maintenance purposes. In addition, a separate assembly opening is provided for the maintenance of the belt drive 62 and the drive shaft 41.
  • the feedthroughs of the belt drive 62 and the carrier of the support frame 80 through the fine material space are encapsulated and provided with a pointed roof in order to prevent the fine material 280 from being packed up.
  • the fine material or the contaminants can also be removed by screw conveyors instead of one or more speed-controlled conveyor belts 29, 35.
  • Fig. 4 shows in a sectional view from above a top view of the in Fig. 3 shown shredding device according to the invention.
  • the motor bracket with the drive motor 61, the motor-side belt drive 62 together with the pulley and corresponding tensioning device are shown schematically.
  • the present invention is a shredding device 1 for shredding a wide variety of materials.
  • various flat or two-dimensional wastes such as plastic films, textiles, paper, cardboard boxes or mixed wastes such as household waste and waste similar to household waste can be comminuted with this device.
  • the comminuted fine material fractions can, for example, be further processed to produce alternative fuels. Solid contaminants that can no longer be shredded can, depending on their material composition, be recycled under certain circumstances.
  • the grain sizes of the comminuted material referred to as fines depend on the mesh size of the screen materials 26 or 261, 262 used.
  • the waste material 100 to be comminuted can be dried during the comminution process, for example by introducing hot gas into the comminution drum 20.
  • the initial moisture of the material can be reduced, for example, by around 10%.
