Definitions

  • the invention relates to a device for treating composite elements made of solid organic and / or inorganic composite materials such as metal / metal, plastic / plastic, metal / plastic or mineral compounds with metals and / or plastics, with - a feed channel and a tubular discharge in a housing of the device connecting - flow path for a transport fluid carrying solid particles produced from the composite element (s) by disintegration.
  • a device for treating composite elements made of solid organic and / or inorganic composite materials such as metal / metal, plastic / plastic, metal / plastic or mineral compounds with metals and / or plastics
  • a preferred embodiment of the device is intended to be provided with a family of accelerating tools as a rotor, relative to a stator about a shaft rotating them on plates arranged one above the other, spaced apart on a construction circle, each having a tear-off edge in the direction of flow for generating a vortex form from the transport fluid and its solids load, the plates determining several superimposed acceleration planes within a cylindrical wall of the housing as a stator; the housing, with the plates carrying the acceleration tools, delimits the flow path designed in the manner of an annular space.
  • Composite elements of the type mentioned are, for example, tinned copper conductor tracks of circuits, fiber-reinforced plastics or copper-plated aluminum wires in coextruded or laminated form.
  • metal-metal composites - for coaxial cables for example - primarily consist of a metal carrier, for example an aluminum wire, with a galvanically or thermally applied copper layer, plastic-plastic composites for packaging packaging foodstuffs made of a plastic carrier made of polyamides (PA) with laminated, laminated or co-extruded polyethylene (PE).
  • PA polyamides
  • PE polyethylene
  • synthetic fiberglass epoxy sheet as a carrier with copper coating as the base material for printed circuits.
  • Metal-plastic composites include, among other things, a carrier made of aluminum sheet with a glued-on protective film made of polypropylene (PP) for facade panels and weather protection cladding.
  • the composite elements that must be disposed of in an orderly manner also include residues from the packaging area; It is precisely there that co-extruded and laminated products have so far been irreplaceable, since the materials in the combination have excellent packaging properties.
  • the composite element is disintegrated by means of the grain or particle size, which is smaller than the respective layer thickness of the components.
  • This digestion is generally carried out by means of at least one-stage micronization in appropriate mills, such as hammer, impact or countercurrent mills, optionally with the support of nitrogen for inerting and deep-freezing.
  • DE-A-195 09 808 of the applicant describes a method by means of which solid particles are produced from the composite elements mentioned and these are fed to a transport fluid, such as air, with at least one flow obstacle crossing the flow relative to the flow of the mixture of solid particles and transport fluid is moved as a tear-off edge to form rear vortices which accelerate the mixture. There is a sudden increase in the transition to this rear swirl the acceleration of the solid particles as well as their - which unlocks them - friction against each other.
  • the mixture of transport fluid and solid particles is fed to the separation or disintegration process at the tear-off edges with an acceleration of 20 to 25 m / sec 2 after the composite elements to be treated have been roughly crushed or compressed before the separation or disintegration process.
  • the composites are pre-comminuted into particles that are above the grain size of fine comminutions, and then fed to the separation or disintegration zone, thus accelerated in the air stream.
  • the individual substances in the composite are released, the physically different metallic layers as well as the plastic layers separate from one another. This detachment takes place along the phase boundaries.
  • the device according to DE-A-195 09 808 has in a tubular housing a rotor with a vertically standing shaft, which delimits a flow path between a feed channel connected to the lower region of the housing and a tubular discharge provided in the ridge region.
  • a comminution mill with a rotor comprising several turntables and this extensive cylindrical housing has become known, in which the material to be ground is guided by a screw to the lower end of the rotor and then by the air flow one above the rotor a sieve plate and below the rotor bearing - spanning fan is detected.
  • the upward migrating regrind is chopped up by so-called plaques de broyage, that is to say from grinding or crushing plates which protrude radially from rotating rotor plates and are arranged close to the housing wall.
  • a plant according to DE-A-42 13 274 contains the comminution mill of FR-A-1 562 613 as one of the units and describes a special design of grinding plates attached to the stator and a radial discharge channel near the grinding plates. In the discharge channel, a triangular baffle bar for the regrind is arranged in plan view.
  • the inventor has set himself the goal of developing a device of the type mentioned at the outset, with which a favorable separation of composite elements into fractions, particularly for the recovery of valuable materials, can take place; the composite materials should be able to be brought back into the economic cycle without polluting the environment.
  • the device should be easy to adapt to the process conditions.
  • the cross-section of the tubular discharge is assigned, on the one hand, a conveying element with plate-like surface elements which are movable in cross-section and run in the flow direction, and, on the other hand, a grating or sieve element which at least partially spans the cross-section.
  • the surface elements are advantageously radially of a rotatably mounted one running in the flow direction Shaft protruding plates aligned with two of their edges parallel to the longitudinal axis of the shaft, which are adapted to the longitudinal section of the interior of a tubular housing and can be rotated like a paddle in this interior.
  • the disk-like housing is inserted between two — preferably coaxial — sections of the discharge pipe in such a way that the plates of the shaft run over the mouths of the pipe sections located in the upper housing area. It has proven to be advantageous for the shaft, which is mounted in the end walls of the housing, to be provided outside the housing interior in order to be able to adapt the plate size to the longitudinal section of this housing interior following the diametrals.
  • the solid particles traveling through the pipe cross section in the flow direction reach a sieve element in front of the opposite mouth of the pipe section that continues the discharge path;
  • the flat sieve element is assigned to the edges of the plates pointing in the direction of flow, preferably spanned and fixed on them, and retains the larger particles in the interior of the housing in accordance with its mesh size.
  • two plates projecting adjacent to the shaft with the sieve element or grating extending transversely to one end form a movable receiving space for the solid particles retained by the sieve element. These are transported by the rotating plates around the shaft to an outlet opening which is located in the cylindrical wall of the housing, preferably at the deepest part of the interior below the mouths of the sections of the discharge tube.
  • the device according to the invention allows a simple separation of solid particles from the remaining flow.
  • Composite elements made of solid organic and / or inorganic composite materials - such as composites made of metal / metal, plastic / plastic, metal / plastic or mineral composites with metals and / or plastics - are crushed to a grain size of about 5 to 50 mm and then in a separating or unlocking device 10 selectively unlocked by an acceleration process.
  • the unlocking device 10 has, above a cuboid base frame 12, a rotor 14 with a vertically arranged rotor shaft 16 engaging in the base frame 12 and a base attachment 18 with adjustable supports 19 for a drive unit 20; the lower end 15 of the rotor shaft 16 carries a V-groove sleeve 22 which is connected to a drive shaft 21 of the drive unit 20 by means of several narrow V-belts indicated at 23.
  • the distance a between the rotor axis A and the drive axis B is variably adjustable by moving the drive unit.
  • a cylindrical wall 24 of a housing 25 Surrounding the rotor 14, for example the outside diameter d of 1200 mm, above the base frame 12 is a cylindrical wall 24 of a housing 25, the housing interior 26 of which is closed at the top by means of an exchangeable housing cover 27; on the inside, this carries a central shoulder 28 of diameter b of approximately 600 mm.
  • the disc-like bottom 28 a of this approach 28 runs near the upper end 17 of the rotor 16 and offers a receptacle 29 for this in FIG. 1.
  • a feed channel 34 for the air-controlled flow of pre-comminuted composite elements is provided near the rotor shaft 16 which passes through the cover plate 30 with play.
  • the feed channel 34 is equipped with at least two openings 32.
  • a heavy material discharge 36 runs; Heavy suspended parts fall downward from the air-controlled material flow and are removed from the cover plate 30 thanks to the heavy material discharge 36.
  • a discharge pipe 38 with a connecting flange 39 protrudes tangentially from the housing wall 24. Since the discharge tube 38 is fixed on the housing 25, that housing cover 27 can be raised without any problems — for example for replacing the rotor 14. Housing doors and control boxes or similar attachments attached to the housing 25 are not shown.
  • the rotor shaft 16 is supported in the area of that cover plate 30 by means of an angular contact ball bearing 40 in a shaft tube 42, its lower end, which cannot be seen, rests in a further ball bearing.
  • FIG. 3 a collar 44 of the free upper part of the rotor shaft 16 overlying the fixed bearing 40 can be seen.
  • This free rotor part defines the active rotor area with the acceleration plates 46 surrounding it.
  • the acceleration plates 46 each offer an acceleration plane and carry a plurality of radially projecting acceleration fins 48 as tools on their peripheral edge. Accelerating fins 48 adjacent to an acceleration plate 46 determine a center point angle of approximately 10 ° here.
  • the plate-like acceleration fins 48 are specially designed depending on the respective application.
  • the lowest of the acceleration plates 46 forms a structural unit with a distribution disk 50.
  • the lower assembly 46/50 mentioned is spanned by four - or more - further plate-like acceleration planes 46, which axially lie on the free part of the rotor shaft 16 by means of hub bushes 47.
  • a baffle plate 54 forms a baffle plane from two disks fixed to a central holding bush.
  • the upper disk of the storage plate 54 is of smaller diameter than the lower disk.
  • Spacers 56 are located between the disks at a distance from the rotor axis A.
  • the retaining sleeve of the storage plate 54 is spanned by a shoulder cover 58 screwed to the rotor shaft 16 in the rotor axis A.
  • Tensioning rods 59 running parallel to the rotor axis A penetrate both the shoulder cover 58 and thrust channels in the hub bushes 47 lying one on top of the other and are seated at the end in the distribution disk 50.
  • the cylindrical wall 24 of the housing 25 serving as a stator delimits the outside of the flow path for a mixture of solid particles and carrier fluid, for example air, introduced through the feed channel 34 near the rotor shaft 16; the other side of the flow path is delimited by the acceleration fins or plates 46 in the five floors indicated in FIG. 3.
  • the mixture of solid particles and transport air is fed on the distribution disk 50 to a narrow annular space in the area of the acceleration fins 48 of the assembly 46/50, which is present between the housing wall 24 and the rotor 14, in such a way that it flows against the direction of rotation x of the rotor 14. This creates - in the direction of rotation x - a rear vortex behind each acceleration fin 48, which produces a tear-off edge.
  • the mixture flow is accelerated abruptly, the solid particles are rubbed against each other and thereby dissolved into their components.
  • the peripheral speeds of the tear-off edge, process temperature and air flow rate can be preselected and adjusted.
  • the mixture flow can briefly expand in order to then reach the downstream annular space. In the region of the storage plate 54, the portions of the solid particles which are guided upwards and thereby broken down are passed to the discharge pipe 38.
  • annular element 60 is inserted into the housing wall 24 above the storage plate 54, from which a radial tube 62 flanged on the outside extends.
  • a guiding device 64 which projects approximately radially into the housing interior 26 and is sketched in FIG. 5, is inserted into this.
  • This guide insert 64 protrudes into the housing interior 26 with a cantilever 68, which offers a vane surface 66 curved in plan view against the flow direction y.
  • the free radial collar length e of this guide or steering insert 64 is adjustable; the latter is provided with a strip-like stop section 69 here, which can be screwed laterally in the radial tube 62 in different insertion lengths t.
  • This cantilever length e is selected such that the end edge 67 of the blade surface 66, which is parallel to the rotor axis A, on the one hand on the cantilever head 68, which is approximately triangular in plan view, in the boundary region between the outer movement path of coarse particles Q which can be seen in FIG. 5 and on the other hand the inward trajectory of fine particles Q 1 runs; the coarse particles Q are skimmed off from the guide insert 64 and discharged through the radial tube 62 serving as particle discharge.
  • the unlocking device 10 a of FIG. 4 has several — at least two — of the described ring elements 60 one above the other; the different types of particles Q, Q 1 are discharged separately.
  • the composite element given to the unlocking device 10, 10 a is released by releasing the different physical properties of the composite materials - in particular the density, elongation at break, restoring force, thermal expansion and heat transfer as well as the elasticity and thus connected molecular structural differences - selectively unlocked, and the adhesions of the composite materials are removed from each other.
  • the treatment in the unlocking device 10, 10a results in the composite element being broken down into different structures, the individual components also behaving differently in terms of dimension and geometry owing to their different physical characteristics.
  • the composite elements can be compressed before digestion. It has been shown that with this selective digestion, the components made of polyethylene remain essentially unchanged, while metallic components, for example made of aluminum - which were previously in flat form - are deformed into onion-like structures.
  • Plastic composites for example polystyrene / polyethylene, break down into different structures without any significant deformation with discernible differences in particle sizes; these are considerably larger than the aluminum onion structures mentioned.
  • the selective digestion removes the individual layers of the composite element without reducing the layer thickness of the components.
  • a separating or catching device 70 is installed in a discharge pipe 38 a , with which larger particles - indicated at Q - are removed from the material flow, in which only the smaller particles Q 1 then remain.
  • an inner diameter of a tubular housing is inserted i 72 the inner diameter of n; the latter is longer than twice the inner diameter i of the discharge tube 38 a .
  • a shaft 74 with paddle-like plates 76 oriented along the housing axis E and projecting radially therefrom - one of which is optically highlighted in FIG. 6, partially hatched - is rotatably mounted in bearings 75 as a conveying element 78; the bearings 75 are located in the end walls 73 of the housing.
  • the shaft 74 is connected via an endless belt 80 to a drive 82, which stands on a side base 79, and can be rotated by the latter so that the plates 76 filling the longitudinal section of the housing interior 84 fill the latter move evenly.
  • a grid or sieve 86 is spanned at the rear edges 77 of the plates 76 in the flow direction y, which separates those coarse particles Q from the particles Q 1 of smaller grain sizes; the retained coarse particles Q are carried within the housing 72 and fed to a discharge opening 88 located in its base area, which is delimited laterally by angle profiles 90 in FIG. 7.
