Definitions
- the invention relates to a device for processing plastic waste, with a shredding device arranged in a housing and rotatable about an axis of rotation, which carries a plurality of knives on its periphery, and an extruder with an extruder screw, the housing having a feed opening for feeding plastic waste Shredding device and a discharge opening for dispensing shredded plastic waste to the extruder, according to the preamble of claim 1.
- the material to be processed in conventional recycling machines is first shredded via a mill with an attached perforated screen and then, optionally via an intermediate storage silo and a deep-cut stuffing screw, fed to an extruder.
- the disadvantage of this arrangement is that, in addition to the space-consuming and expensive construction, the pre-shredding energy that is generated in the shredding instrument is lost.
- Another technological approach is to mainly feed film waste in uncrushed form directly into an extruder screw with an enlarged diameter in its feed area, which subsequently tapered in the screw core or in diameter, viewed in the direction of material flow.
- a disadvantage of this design is that the extruder screw in the feed area exerts little wall friction on the loose plastic due to the low bulk density of the material and therefore it is likely that the material will rotate in the feed area, which prevents the material from being fed, thereby "pumping" the Particularly when this device is loaded with uncrushed edge trim waste, the delivery speed of which is greater than the peripheral speed of the screw, this leads to an uneven loading of the extruder.
- a device is known from WO 9816360 in which the loose plastic material is cut up by means of a comminution shaft and compacted by means of a screw conveyor located on the shaft before a tangentially flanged extruder is fed.
- this device has the disadvantage that the material is always transported in the direction of the discharge-side bearing and the deflection therefore leads to increased thermal degradation and consequently to increased bearing stress.
- the extruder is fed by two counter-rotating screw conveyors located on a shaft, the extruder being positioned in the middle between the screws.
- a disadvantage of this device is that the plastic material has to be pre-shredded.
- comminution shaft runs parallel to the extruder screw and conveys material into the screw. Since the shredding shaft is parallel to the extruder and therefore the extruder shaft has to be extended by the width of the shredding device, the space requirement of this device is very high.
- the present invention attempts to eliminate the disadvantages of the known machines by developing the device mentioned at the outset in such a way that the comminution device is arranged at such a small distance from the extruder screw that effective shear gaps are formed between the knives of the comminution device and a helix of the extruder screw are.
- the shear gaps formed between the knives and the extruder screw spiral already sufficiently shredded plastic parts. pressed into the extruder, but on the other hand still insufficiently shredded, larger material parts that could clog the feed area of the extruder, either shredded directly in the shear gaps or returned to the area between the inner wall of the housing and the rotating shredding device and thereby subjected to renewed shredding. Furthermore, the formation of material bridges or tunnels is effectively prevented.
- the actual distance between the knives and the extruder screw is dependent on the type of plastic material to be processed, in particular on its bulk density, and can be greater the higher the bulk density. Generally, this distance is chosen to be less than 10 cm, preferably less than 5 cm, most preferably less than 3 cm. The latter value is particularly suitable for shredding film waste and thin plastic strips.
- the axis of rotation of the rotatable comminution device is arranged at an angle of 60-120 °, preferably approximately at a right angle, to the axis of rotation of the extruder screw. It also proves to be advantageous if the comminution device has a horizontal axis of rotation and is arranged above the extruder. With this type of construction, the shredded plastic material falls through its discharge weight onto the extruder screw due to its own weight.
- the knives arranged on the circumference of the shredding device should be helical be arranged.
- devices can be provided on the inner wall of the housing surrounding the shredding device to support the material conveyance for the discharge opening, in particular helical grooves or webs, and / or air nozzles.
- a particularly preferred embodiment of the invention is characterized in that the discharge opening is arranged approximately at the point of bisection of the length of the comminution device.
- the speed of the extruder screw can be regulated as a function of the load on the comminution device, the load on pressure measuring cells or the current consumption of a drive motor of the comminution device preferably being determinable.
- a pocket-like extension can be provided as a buffer for shredded plastic waste in the feed area of the extruder screw.
- a driven slide can be provided which interacts with the comminution device in order to press the plastic material against the knives depending on the load on the axis of rotation of the comminution device.
- Excellent material feed can be achieved if the extruder screw is expanded to a larger diameter in the feed area and / or is tapered towards the material outlet end.
- the processing device it is desirable for the processing device to have a slim overall design.
- the axis of rotation of the shredding device is arranged axially parallel to the extruder screw.
- FIG. 1 shows a first embodiment of the device according to the invention for processing plastic materials in longitudinal section
- FIG. 2 shows the same device in plan view, partly in section
- Fig. 3 shows a second embodiment of a device according to the invention in longitudinal section.
- FIGS. 1 and 2 Shown is a device for processing plastic waste, with a shredding device 9 arranged in a housing 1 and rotatable about an axis of rotation 2 (arrow A), which carries a plurality of knives 3 on its circumference.
- the shredding device 9 is located above an extruder with an extruder screw 4 and a screw helix 4a, the screw 4 being rotatable in the direction of arrow D and discharging the extruded plastic material in the direction of arrow C.
- the housing 1 has a feed opening 5 for feeding (arrow B) plastic waste to the shredding device 9 and a discharge opening 6 for discharging shredded plastic waste to the extruder.
- the shredding device 9 or its knives 3 can be moved past the extruder screw 4 at such a small distance h that effective shear gaps are formed between the knives 3 of the shredding device 9 and the helix 4a of the extruder screw 4. Due to the shear gaps formed between the knives 3 and the extruder screw helix 4a, sufficiently shredded plastic parts are pressed into the extruder on the one hand, but on the other hand insufficiently shredded material parts that could clog the discharge opening 6 or the feed area of the extruder are either shredded directly in the shear gaps or again returned to the area between the inner wall of the housing and the rotating comminution device 9 and thereby subjected to a further comminution.
- the distance h between the knives 3 of the shredding device and the extruder screw 4a, ie the width of the Shear gap is less than 10 cm, preferably less than 3 cm, depending on the material fed.
- the axis of rotation 2 of the rotatable comminution device 9 is arranged at an angle ⁇ of 90 ° to the axis of rotation of the extruder screw 4, both the axis of rotation 2 and the extruder screw 4 lying horizontally.
- Knives 3 arranged in the comminution device are arranged in a helical shape (see FIG. 2), so that they support transport of the plastic material to discharge opening 6. Furthermore, the discharge opening 6 lies approximately in half the length of the comminution device 9, the material being moved from one to the other by the opposite direction of rotation of the helical arrangement of the knives.
- the rotary bearings located at the ends of the shredding device and thus the pressure which the plastic material exerts on the bearing points is reduced.
- Helical webs 7 and air nozzles 8 are provided to support the material conveyance towards the discharge opening 6.
- the speed of the extruder screw 4 is preferably regulated as a function of the load on the comminution device 9.
- Fig. 3 a further embodiment of the invention is shown, which differs from the device according to FIGS. 1 and 2 only in that the comminution device 9 cooperates with a driven slide 10 which the plastic material depending on the load on the axis of rotation 2 Crushing device presses against the knife 3.
- the same reference numerals being used for identification.
- the shape of the extruder screw which can be expanded to a larger diameter in the feed area, for example, and / or tapered towards the material outlet end. It is also expedient to provide a pocket-like extension in the feed area of the extruder screw as an intermediate store for shredded plastic waste.
- the axis of rotation of the shredding device can be arranged axially parallel to the extruder screw.
