Description

Technical Field

[0001] The invention relates to the field of waste recycling, in particular to a device for recycling and processing plastic production waste. Background Art

[0002] Plastic waste refers to plastic products generated during the production, processing and use process that have lost their original use value or have not lost their use value but have been discarded. It covers all kinds of plastic products such as plastic packaging materials, plastic containers, plastic parts, plastic films, etc.

[0003] Recycling plastic waste can reduce the pollution of soil and the hindrance of plant root growth caused by plastic particles, thus playing a role in environmental protection. At the same time, after sorting, cleaning, crushing and other processing, recycled plastics can be directly used as raw materials to produce some plastic products with low quality requirements, such as plastic trash cans, plastic pallets, etc.

[0004] In the existing technology, there is a method of directly crushing plastic waste. During use and observation, it was found that some iron impurities are mixed in the plastic waste. These iron impurities will increase the hardness of the material, thereby aggravating the wear of the crushing roller during operation and shortening the service life of the equipment.

[0005] Therefore, in order to solve the above problems, a plastic production waste recycling and processing device is proposed. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is: a plastic production waste recycling and processing device described in the present invention includes a conveying component, an iron removal component, a crushing component, and a collecting component; the conveying component includes a climbing conveyor; the climbing conveyor is used to lift and convey plastic waste; the iron removal component includes an equipment box; a magnet is provided inside the equipment box; a column is fixedly connected to one side of the equipment box; a cylinder is fixedly connected to the top of the equipment box; a mounting bracket is fixedly connected to the output end of the cylinder; positioning rods are symmetrically fixedly connected to both sides of the equipment box; the mounting bracket and the positioning rod are set through and are slidably connected; the A base plate is fixedly connected to the bottom of the mounting frame, and a plurality of grooves are provided on the surface of the base plate; a collection box is provided on one side of the equipment box, and the top of the collection box is flared; the collection box is used to collect iron filings at the bottom of the base plate; the crushing assembly is used to crush plastic waste; the collection assembly is used to recycle the crushed plastic debris; by setting up the equipment box, the iron impurities at the bottom of the base plate can be desorbed, thereby realizing the removal of iron impurities in the waste by the device, facilitating the subsequent crushing of the waste by the device, and at the same time, by starting the cylinder, the base plate can be driven to desorb iron impurities, thereby realizing the rapid desorption of iron impurities by the device.

[0008] Preferably, a slide rail is provided outside the column, and the column is slidably connected to the slide rail; a worm is rotatably connected to the inner wall of the slide rail; a worm gear is rotatably connected to the inside of the slide rail; the worm and the worm gear are in meshing relationship; a screw rod is fixedly connected to the top of the worm gear; the screw rod is threadedly connected to the column; by rotating the worm and the worm gear, the height of the iron removal assembly can be adjusted to adapt to the stacking height of the materials on the surface of the climbing conveyor, thereby enhancing the adsorption effect of the magnet in the equipment box on the iron impurities in the waste materials.

[0009] Preferably, a connecting frame is fixedly connected to one side of the equipment box; an air extraction end is fixedly connected to one side of the connecting frame; a first motor is fixedly connected to the other side of the connecting frame; a pipe fitting is fixedly connected to the output end of the first motor, and the pipe fitting is rotatably connected to the connecting frame; the pipe fitting is in communication with the air extraction end and is rotatably connected to the air extraction end; multiple sets of sleeves are provided through the surface of the pipe fitting; a rod is fixedly connected to the inner wall of the pipe fitting; multiple connecting plates are fixedly connected to the outer wall of the rod; the connecting plates are arranged corresponding to the grooves, and each set of sleeves is arranged corresponding to the connecting plates; a blocking assembly is provided between the sleeve and the connecting plate; the blocking assembly is used for blocking the sleeve located at the bottom; an impurity removal assembly is provided at the end of the sleeve; the impurity removal assembly is used for intercepting iron impurities; when desorbing the iron impurities at the bottom of the bottom plate, the first motor can be started and the air extraction end can be connected to a vacuum pump. After the first motor is started, it will drive the pipe fitting to drive the sleeves to rotate. Due to the rotational connection relationship between the air extraction end and the pipe fitting, the pipeline between the vacuum pump and the air extraction end will not be wound. At the same time, a negative pressure state will be formed inside the pipe fitting and at the sleeves. Under the action of the negative pressure, the cylinder will drive the bottom plate to slide on the top of the pipe fitting after being started, and the top sleeves will forcibly desorb the inner wall of the groove at the bottom of the bottom plate under the action of the negative pressure, thereby reducing the iron impurities adhered to the inner wall of the groove. At the same time, due to the interception of the impurity removal assembly, the iron impurities will not reach the vacuum pump through the pipeline. As the pipe fitting rotates, when the sleeve adsorbed with iron impurities rotates to the lower position, the blocking assembly can block the sleeve and isolate the air flow. At this time, the iron impurities will fall into the collection box under the action of gravity, realizing the forced desorption of the iron impurities in the groove by the device and improving the smoothness of the inner wall during the desorption of the bottom plate.

[0010] Preferably, the plugging assembly includes a spring; one end of the spring is fixedly connected to the connecting plate; the other end of the spring is fixedly connected with a plug, and the outer wall and the end of the plug are provided with pores; the plug is slidably connected to the sleeve; when the sleeve is at the lowest position, the plug will pull the spring under the action of gravity and make the spring in a stretched state. At this time, the pores on the surface of the spring will be inside the sleeve, so that the bottom sleeve will be in a closed state, while the pores on the surface of the plug at the sleeve in other positions will be exposed, so that a negative pressure state can be maintained inside the sleeve to adsorb iron impurities, thereby realizing the forced desorption of iron impurities inside the groove by the device and improving the cleaning effect during the desorption of the bottom plate.

[0011] Preferably, the impurity removal assembly includes a suction nozzle; the suction nozzle is threadedly connected to the sleeve; a filter pad is detachably connected to the inner wall of the suction nozzle; by providing the suction nozzle, the opening shape at the end of the suction nozzle can roughly adapt to and cover the inner wall area of the groove, so as to ensure the desorption effect of the end of the sleeve on the inner wall of the groove. The filter pad can intercept iron impurities. At the same time, the filter pad and the suction nozzle can be specifically connected by a compression spring, which is convenient for replacing the filter pad. At the same time, since the suction nozzle is threadedly connected to the sleeve, different suction nozzles can be selected according to the grooves with different inner wall sizes, improving the flexibility of the device during forced desorption of the groove.

[0012] Preferably, the crushing assembly includes a housing; a second motor is fixedly installed at the bottom of the housing; a crushing roller is rotatably connected to the inner wall of the housing; a belt is sleeved between the output end of the second motor and the second motor; the inner wall of the housing is penetrated and slidably connected with a pressing plate; a crushing tooth is provided at the end of the pressing plate; arms are rotatably connected to both sides of the pressing plate; a circular plate is rotatably connected to one side of the housing, and a crank pin is fixedly connected to the surface of the circular plate; a belt is sleeved between the circular plate and the crushing roller; a chute is provided on the surface of the arm, and the chute on the surface of the arm and the crank pin on the surface of the circular plate are in sliding fit; a filter screen is provided at the bottom of the crushing roller, and the filter screen is fixedly connected to the housing; after the plastic waste is conveyed to the inside of the housing by the climbing conveyor, the second motor will start and drive the crushing roller to rotate through belt transmission. At the same time, the crushing roller will drive the circular plate to rotate through the belt. When the second motor rotates, it will drive the arm to swing reciprocally along the contour of the circular plate through the cooperation relationship between the crank pin on the surface and the chute on the surface of the arm. When the arm swings, it will drive the pressing plate to move reciprocally along the housing. At this time, the waste inside the housing will be continuously pushed between the crushing roller and the pressing plate and crushed by the rotating crushing roller as the pressing plate moves reciprocally. The waste on the surface of the pressing plate will also slide down to the inner wall of the housing and be pushed to the crushing roller by the pressing plate during the reciprocating movement of the pressing plate, thereby realizing the uniform crushing of the waste inside the housing. At the same time, by providing the filter screen, it can also ensure that the waste that is not completely crushed will be intercepted, thereby increasing the contact area between the waste and the crushing roller.

[0013] Preferably, a centrifugal fan is fixedly installed at the top of the housing; the input end of the centrifugal fan is connected to the top of the housing through a pipeline; the output end of the centrifugal fan is communicated with a dust removal box through a pipeline; one side of the dust removal box is communicated with an exhaust pipe; a filter bag is arranged inside the dust removal box; a rotating shaft is arranged through one side of the dust removal box and is rotatably connected; a plate member is fixedly connected to the rotating shaft located inside the dust removal box; a belt is sleeved between the rotating shaft and one side arm; when the crushing roller crushes the waste, due to the extrusion and shearing action, dust waste gas will be generated inside the housing. At this time, the centrifugal fan can be started to absorb these waste gases and transport them to the dust removal box. The centrifugal fan is a mature existing technology, so its internal structure diagram is not shown. The waste gas will pass through the filter bag under the action of positive pressure, and the filter bag will filter the dust in the waste gas. At the same time, the reciprocating swing arm will drive the rotating shaft to reciprocate through belt transmission, so that the rotating shaft can drive the plate member to repeatedly strike the filter bag, so that the dust attached to the inner wall of the filter bag will fall off and redistribute, reducing the dust accumulated on the inner wall of the filter bag. The air after dust removal can be discharged through the exhaust pipe. It is worth mentioning that the installation method of the filter bag can refer to the bag filter in the existing technology.

[0014] Preferably, a connecting part is fixedly connected to the bottom of the filter bag; the bottom of the connecting part is threadedly connected with a storage box; after repeated beating by the plate member, most of the dust on the inner wall of the filter bag will be concentrated in the bottom area of the filter bag. These dusts will fall into the storage box through the connecting part. The staff can remove the dust stored in the storage box by removing the maintenance plate on one side of the dust removal box and rotating the storage box, realizing the rapid discharge of the dust in the filter bag, and then simplifying the operation of the device that requires additional disassembly of the filter bag.

[0015] Preferably, the collection component includes a box body; the box body is located at the bottom of the crushing roller; a filter plate is fixedly connected to the inner wall of the box body, and the filter plate is inclined; a chute is fixedly connected to the bottom of the inner side wall of the box body, and the top of the chute is fixedly connected to the bottom of the filter plate; the plastic debris crushed by the crushing roller will fall into the box body through the filter screen. At this time, the filter plate will screen the debris again. The debris with smaller particle size will enter a chamber in the box body through the filter plate and can be reduced from local accumulation under the guiding action of the inclined surface of the chute, while the debris with larger particle size will enter another chamber through the filter plate, realizing the screening of the debris by the device, so as to facilitate the use of the debris by the device.

[0016] Preferably, a plurality of partition plates are fixedly connected to the bottom of the inner wall of the box body and the surface of the chute; a guiding plate is fixedly connected to the end of the partition plate; by arranging the partition plates and the guiding plates, the falling debris in the chamber can be guided and separated, so that these debris can be more evenly distributed in the cavities formed by the partition plates, further reducing the situation of local accumulation of debris in the inner chamber of the box body, and thus reducing the situation of debris overflow in the box body.

[0017] The beneficial effects of the present invention are as follows: 1. A plastic production waste recycling and treatment device according to the present invention can desorb iron impurities at the bottom of the bottom plate through the setting of the equipment box, thereby realizing the removal of iron impurities in the waste by the device, facilitating the subsequent crushing treatment of the waste by the device. At the same time, by starting the cylinder, the bottom plate can be driven to desorb iron impurities, realizing the rapid desorption of iron impurities by the device.

[0018] 2. A plastic production waste recycling and treatment device according to the present invention can adjust the height of the iron removal component by rotating the worm and the worm wheel to adapt to the accumulation height of the materials on the surface of the climbing conveyor, thereby improving the adsorption effect of the magnet in the equipment box on the iron impurities in the waste.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] The following gives specific embodiments.

[0024] Please refer to Figures 1 to 12 As shown in the figure, a plastic production waste recycling and treatment device described in an embodiment of the present invention includes a conveying component, a magnetic separation component, a crushing component, and a collection component; the conveying component includes an inclined conveyor 1; the inclined conveyor 1 is used for lifting and conveying plastic waste; the magnetic separation component includes an equipment box 12; a magnet is provided inside the equipment box 12; a column 13 is fixedly connected to one side of the equipment box 12; a cylinder 14 is fixedly connected to the top of the equipment box 12; the output end of the cylinder 14 is fixedly connected to a mounting bracket 16; positioning rods 15 are symmetrically and fixedly connected to both sides of the equipment box 12; the mounting bracket 16 and the positioning rods 15 are arranged in a penetrating manner and are in sliding connection; a bottom plate 17 is fixedly connected to the bottom of the mounting bracket 16, and a plurality of grooves 18 are formed on the surface of the bottom plate 17; a collection box 19 is provided on one side of the equipment box 12, and the top of the collection box 19 is provided with a flared opening; the collection box 19 is used for collecting iron filings at the bottom of the bottom plate 17; the crushing component is used for crushing plastic waste; the collection component is used for recycling the crushed plastic chips; During operation, plastic waste can be conveyed to the surface of the climbing conveyor 1 through a conveyor. The climbing conveyor 1 will lift and convey these wastes into the interior of the housing 6. The climbing conveyor 1 is a mature existing technology, so its specific structure will not be described in detail. During the conveying process of the waste on the surface of the climbing conveyor 1, it will pass by the equipment box 12. The magnet in the equipment box 12 will adsorb the iron impurities in the waste under the magnetic action, so that these iron impurities will be adsorbed on the bottom of the bottom plate 17. And through a plurality of grooves 18 are opened at the bottom of the bottom plate 17, the adsorption area at the bottom of the bottom plate 17 is enlarged. The waste after iron removal will enter the crushing assembly and be extruded and crushed. Finally, the crushed waste debris will be uniformly collected through the collection assembly. When it is necessary to remove the iron impurities at the bottom of the bottom plate 17, the cylinder 14 can be started to radially control the mounting frame 16. The mounting frame 16 will slide along the positioning rod 15, so that the bottom plate 17 will also move along the equipment box 12 and approach the collection box 19. As the bottom plate 17 moves away from the magnet in the equipment box 12, the iron impurities adsorbed on the bottom of the bottom plate 17 will fall into the interior of the collection box 19 under the action of gravity, realizing the desorption of the iron impurities at the bottom of the bottom plate 17 by the device. It is worth mentioning that the placement of the magnet belongs to the mature existing technology, so it is not shown in the figure; by setting the equipment box 12, the iron impurities at the bottom of the bottom plate 17 can be desorbed, thereby realizing the removal of the iron impurities in the waste by the device, facilitating the subsequent crushing treatment of the waste by the device. At the same time, by starting the cylinder 14, the bottom plate 17 can be driven to desorb the iron impurities, realizing the rapid desorption of the iron impurities by the device.

[0025] Please refer to Figure 3 and Figure 4 As shown, a slide rail 2 is provided outside the column 13, and the column 13 is slidably connected to the slide rail 2; a worm 22 is rotatably connected to the inner wall of the slide rail 2; a worm gear 23 is rotatably connected to the inside of the slide rail 2; the worm 22 and the worm gear 23 are in a meshing relationship; a screw 24 is fixedly connected to the top of the worm gear 23; the screw 24 is threadedly connected to the column 13; When processing the waste, the staff can drive the worm 22 to rotate by turning the handle on one side of the worm 22. The worm 22 will mesh with the worm gear 23 and cause the worm gear 23 to rotate. The worm gear 23 will drive the screw 24 to rotate, and the column 13 will slide vertically along the slide rail 2 under the threaded cooperation with the screw 24, so as to control the height of the iron removal assembly through the column 13 to adapt to the height of the waste on the surface of the climbing conveyor 1, ensuring that the magnet in the equipment box 12 can effectively adsorb the iron impurities in the waste. At the same time, because the meshing of the worm 22 and the worm gear 23 has self-locking property, the stability of the iron removal assembly during operation can be ensured; by rotating the worm 22 and the worm gear 23, the height of the iron removal assembly can be adjusted to adapt to the stacking height of the materials on the surface of the climbing conveyor 1, thereby improving the adsorption effect of the magnet in the equipment box 12 on the iron impurities in the waste.

[0026] Please refer to Figures 3 to 7 As shown, a connecting frame 3 is fixedly connected to one side of the equipment box 12; an air extraction end 32 is fixedly connected to one side of the connecting frame 3; a first motor 34 is fixedly connected to the other side of the connecting frame 3; a pipe fitting 33 is fixedly connected to the output end of the first motor 34, and the pipe fitting 33 is rotatably connected to the connecting frame 3; the pipe fitting 33 is in a communicating relationship with the air extraction end 32, and the pipe fitting 33 is rotatably connected to the air extraction end 32; multiple sleeves 35 are arranged through the surface of the pipe fitting 33; a rod 36 is fixedly connected to the inner wall of the pipe fitting 33; multiple connecting plates 37 are fixedly connected to the outer wall of the rod 36; the connecting plates 37 are correspondingly arranged with the grooves 18, and each group of sleeves 35 is correspondingly arranged with the connecting plates 37; a plugging component is arranged between the sleeve 35 and the connecting plate 37; the plugging component is used to plug the sleeve 35 at the bottom; a impurity removing component is arranged at the end of the sleeve 35; the impurity removing component is used to intercept iron impurities; When desorbing the iron impurities at the bottom of the bottom plate 17, the first motor 34 can be started and the air extraction end 32 can be connected to a vacuum pump. After the first motor 34 is started, it will drive the pipe fitting 33 to drive the sleeve 35 to rotate. Due to the rotational connection relationship between the air extraction end 32 and the pipe fitting 33, the pipeline between the vacuum pump and the air extraction end 32 will not be wound. At the same time, a negative pressure state will be formed inside the pipe fitting 33 and at the sleeve 35. Under the action of the negative pressure, after the cylinder 14 is started, it will drive the bottom plate 17 to slide on the top of the pipe fitting 33, and the top sleeve 35 will forcibly desorb the inner wall of the groove 18 at the bottom of the bottom plate 17 under the action of the negative pressure, thereby reducing the iron impurities adhered to the inner wall of the groove 18. At the same time, due to the interception of the impurity removing component, the iron impurities will not reach the vacuum pump through the pipeline. As the pipe fitting 33 rotates, when the sleeve 35 adsorbed with iron impurities rotates to a low position, the plugging component can plug the sleeve 35 and isolate the air flow. At this time, the iron impurities will fall into the collection box 19 under the action of gravity, realizing the forced desorption of the iron impurities in the groove 18 by the device and improving the smoothness of the inner wall of the bottom plate 17 during desorption.

[0027] Please refer to Figure 6 and Figure 7 As shown, the plugging component includes a spring 4; one end of the spring 4 is fixedly connected to the connecting plate 37; the other end of the spring 4 is fixedly connected to a plug 42, and the outer wall and the end of the plug 42 are both provided with pores; the plug 42 is slidably connected to the sleeve 35; When the casing 35 is at the lowest position, the plug 42 will pull the spring 4 under the action of gravity and keep the spring 4 in a stretched state. At this time, the holes on the surface of the spring 4 will be inside the casing 35, so that the bottom casing 35 will be in a closed state, while the holes on the surface of the plug 42 at the other positions of the casing 35 will be exposed, so that a negative pressure state can be maintained inside the casing 35 to adsorb iron impurities, thereby realizing the forced desorption of the iron impurities inside the groove 18 by the device and improving the cleaning effect during the desorption of the bottom plate 17.

[0028] Please refer to Figure 7 As shown, the impurity removal component includes a suction nozzle 5; the suction nozzle 5 and the casing 35 are in threaded connection; a filter pad 52 is detachably connected to the inner wall of the suction nozzle 5; By setting the suction nozzle 5, the opening shape at the end of the suction nozzle 5 can generally adapt to and cover the inner wall area of the groove 18, so as to ensure the desorption effect of the end of the casing 35 on the inner wall of the groove 18. The filter pad 52 can intercept iron impurities. At the same time, the filter pad 52 and the suction nozzle 5 can be specifically connected by a compression spring, which is convenient for replacing the filter pad 52. At the same time, since the suction nozzle 5 and the casing 35 are in threaded connection, different suction nozzles 5 can be selected according to the grooves 18 with different inner wall sizes, improving the flexibility of the device during forced desorption of the groove 18.

[0029] Please refer to Figures 8 to 10 As shown, the crushing component includes a housing 6; a second motor 62 is fixedly installed at the bottom of the housing 6; a crushing roller 63 is rotatably connected to the inner wall of the housing 6; a belt is sleeved between the output end of the second motor 62 and the second motor 62; the inner wall of the housing 6 is penetrated and slidably connected with a pressing plate 66; crushing teeth are provided at the end of the pressing plate 66; support arms 64 are rotatably connected to both sides of the pressing plate 66; a circular plate 65 is rotatably connected to one side of the housing 6, and a crank pin is fixedly connected to the surface of the circular plate 65; a belt is sleeved between the circular plate 65 and the crushing roller 63; a chute is provided on the surface of the support arm 64, and the chute on the surface of the support arm 64 and the crank pin on the surface of the circular plate 65 are in sliding fit; a filter screen 67 is provided at the bottom of the crushing roller 63, and the filter screen 67 and the housing 6 are in a fixed connection relationship; After the plastic waste is conveyed into the interior of the housing 6 by the climbing conveyor 1, the second motor 62 will start and drive the crushing roller 63 to rotate through belt transmission. At the same time, the crushing roller 63 will drive the circular plate 65 to rotate through a belt. When the second motor 62 rotates, it will drive the support arm 64 to swing reciprocally along the contour of the circular plate 65 through the cooperation relationship between the crank pin on its surface and the chute on the surface of the support arm 64. When the support arm 64 swings, it will drive the pressing plate 66 to move reciprocally along the housing 6. At this time, the waste in the housing 6 will be continuously pushed between the crushing roller 63 and the pressing plate 66 with the reciprocating movement of the pressing plate 66 and be crushed by the rotating crushing roller 63. The waste on the surface of the pressing plate 66 will also slide down to the inner wall of the housing 6 during the reciprocating movement of the pressing plate 66 and be pushed by the pressing plate 66 to the crushing roller 63, so as to realize the uniform crushing of the waste in the housing 6. At the same time, by setting the filter screen 67, it can also ensure that the waste that has not been completely crushed will be intercepted, thereby increasing the contact area between the waste and the crushing roller 63.

[0030] Please refer to Figure 10 and Figure 11 As shown, a centrifugal fan 7 is fixedly installed at the top of the housing 6; the input end of the centrifugal fan 7 and the top of the housing 6 are connected by a pipeline; the output end of the centrifugal fan 7 is communicated with a dust removal box 72 through a pipeline; one side of the dust removal box 72 is communicated with an exhaust pipe 73; a filter bag 74 is arranged inside the dust removal box 72; a rotating shaft 75 is arranged through and rotatably connected to one side of the dust removal box 72; a plate member 76 is fixedly connected to the rotating shaft 75 located inside the dust removal box 72; a belt is sleeved between the rotating shaft 75 and one side support arm 64; When the crushing roller 63 crushes the waste, due to the extrusion and shearing action, dust and waste gas will be generated inside the housing 6. At this time, the centrifugal fan 7 can be started to absorb these waste gases and transport them into the dust removal box 72. The centrifugal fan 7 is a mature existing technology, so its internal structure diagram is not shown. The waste gas will pass through the filter bag 74 under the action of positive pressure, and the filter bag 74 will filter the dust in the waste gas. At the same time, the reciprocally swinging support arm 64 will drive the rotating shaft 75 to swing reciprocally through belt transmission, so that the rotating shaft 75 can drive the plate member 76 to repeatedly strike the filter bag 74, so that the dust attached to the inner wall of the filter bag 74 will fall off and be redistributed, reducing the dust accumulated on the inner wall of the filter bag 74. The air after dust removal can be discharged through the exhaust pipe 73. It is worth mentioning that the installation method of the filter bag 74 can refer to the existing technology of bag filters.

[0031] Please refer to Figure 11 As shown, a connecting part 8 is fixedly connected to the bottom of the filter bag 74; the bottom of the connecting part 8 is threadedly connected to a storage box 82; After repeated patting of the plate member 76, most of the dust on the inner wall of the filter bag 74 will concentrate in the bottom area of the filter bag 74. This dust will fall into the interior of the storage box 82 through the connecting portion 8. The staff can remove the dust stored in the storage box 82 by disassembling the inspection plate on one side of the dust removal box 72 and rotating the storage box 82, realizing the rapid discharge of the dust in the filter bag 74, and thus simplifying the operation that the device needs to disassemble the filter bag 74 additionally.

[0032] Please refer to Figure 12 As shown, the collection assembly includes a box body 9; the box body 9 is located at the bottom of the crushing roller 63; a filter plate 92 is fixedly connected to the inner wall of the box body 9, and the filter plate 92 is inclined; a chute 93 is fixedly connected to the bottom of the inner side wall of the box body 9, and the top of the chute 93 and the bottom of the filter plate 92 are in a fixed connection relationship; The plastic debris crushed by the crushing roller 63 will fall into the interior of the box body 9 through the filter screen 67. At this time, the filter plate 92 will screen the debris again. The debris with a smaller particle size will pass through the filter plate 92 and enter a chamber in the box body 9, and under the guiding action of the inclined surface of the chute 93, local accumulation can be reduced. While the debris with a larger particle size will pass through the filter plate 92 and enter another chamber, realizing the screening of the debris by the device, so as to facilitate the use of the debris by the device.

[0033] Please refer to Figure 12 As shown, a plurality of partition plates 1001 are fixedly connected to the bottom of the inner wall of the box body 9 and the surface of the chute 93; a guiding plate 1002 is fixedly connected to the end of the partition plate 1001; By arranging the partition plates 1001 and the guiding plates 1002, the falling debris in the chamber can be guided and separated, so that these debris can be more evenly distributed in the cavity formed by the partition plates 1001, further reducing the situation of local accumulation of debris in the inner chamber of the box body 9, and thus reducing the situation of debris overflow in the box body 9.

[0034] Working principle: Plastic waste is conveyed to the surface of the climbing conveyor 1 through a conveyor. The climbing conveyor 1 will lift and convey these wastes into the interior of the housing 6. The climbing conveyor 1 is a mature existing technology, so its specific structure will not be elaborated here. During the conveying process of the waste on the surface of the climbing conveyor 1, it will pass through the equipment box 12. The magnet in the equipment box 12 will adsorb the iron impurities in the waste under the magnetic action, so that these iron impurities will be adsorbed on the bottom of the bottom plate 17. The bottom of the bottom plate 17 is provided with a plurality of grooves 18, so that the adsorption area at the bottom of the bottom plate 17 is enlarged. The waste after iron removal will enter the crushing assembly and be extruded and crushed. Finally, the crushed waste debris will be uniformly collected through the collection assembly. When it is necessary to remove the iron impurities at the bottom of the bottom plate 17, the cylinder 14 can be started to radially control the mounting frame 16. The mounting frame 16 will slide along the positioning rod 15, so that the bottom plate 17 will also move along the equipment box 12 and approach the collection box 19. As the bottom plate 17 moves away from the magnet in the equipment box 12, the iron impurities adsorbed on the bottom of the bottom plate 17 will fall into the interior of the collection box 19 under the action of gravity, realizing the desorption of the iron impurities at the bottom of the bottom plate 17 by the device. It is worth mentioning that the placement of the magnet belongs to the mature existing technology, so it is not shown in the figure; when processing the waste, the staff can drive the worm 22 to rotate by turning the handle on one side of the worm 22. The worm 22 will engage with the worm gear 23 and cause the worm gear 23 to rotate. The worm gear 23 will drive the screw 24 to rotate, and the column 13 will slide vertically along the slide rail 2 under the thread engagement action with the screw 24, so as to control the height of the iron removal assembly through the column 13 to adapt to the height of the waste on the surface of the climbing conveyor 1, ensuring that the magnet in the equipment box 12 can effectively adsorb the iron impurities in the waste. At the same time, because the engagement between the worm 22 and the worm gear 23 has self-locking property, the stability of the iron removal assembly during operation can be ensured; when desorbing the iron impurities at the bottom of the bottom plate 17, the first motor 34 can be started and the air extraction end 32 can be connected to the vacuum pump. After the first motor 34 is started, it will drive the pipe fitting 33 to drive the sleeve 35 to rotate. Due to the rotational connection relationship between the air extraction end 32 and the pipe fitting 33, the pipeline between the vacuum pump and the air extraction end 32 will not be wound. At the same time, the interior of the pipe fitting 33 and the sleeve 35 will be in a negative pressure state. Under the negative pressure action, when the cylinder 14 is started, it will drive the bottom plate 17 to slide on the top of the pipe fitting 33, and the top sleeve 35 will forcibly desorb the inner wall of the groove 18 at the bottom of the bottom plate 17 under the negative pressure action, thereby reducing the iron impurities adhered to the inner wall of the groove 18. At the same time, due to the interception effect of the impurity removal assembly, the iron impurities will not reach the vacuum pump through the pipeline. As the pipe fitting 33 rotates, when the sleeve 35 adsorbed with iron impurities rotates to a low position, the blocking assembly can block the sleeve 35 and isolate the air flow. At this time, the iron impurities will fall into the interior of the collection box 19 under the action of gravity, realizing the forced desorption of the iron impurities in the groove 18 by the device;When the sleeve 35 is at the lowest position, the plug 42 will pull the spring 4 under the action of gravity and keep the spring 4 in a stretched state. At this time, the holes on the surface of the spring 4 will be inside the sleeve 35 at the bottom, so that the sleeve 35 at the bottom will be in a closed state, while the holes on the surface of the plug 42 at the sleeve 35 in other positions will be exposed, so that a negative pressure state can be maintained inside the sleeve 35 to adsorb iron impurities, thereby realizing the forced desorption of the iron impurities inside the groove 18 by the device and improving the cleaning effect during the desorption of the bottom plate 17; by setting the suction nozzle 5, the opening shape at the end of the suction nozzle 5 can roughly adapt to and cover the inner wall area of the groove 18, so as to ensure the desorption effect of the end of the sleeve 35 on the inner wall of the groove 18. The filter pad 52 can intercept iron impurities. At the same time, the filter pad 52 and the suction nozzle 5 can be specifically connected by a compression spring, which is convenient for replacing the filter pad 52. At the same time, since the suction nozzle 5 and the sleeve 35 are threadedly connected, different suction nozzles 5 can be selected according to the grooves 18 with different inner wall sizes, improving the flexibility of the device during the forced desorption of the groove 18; after the plastic waste is conveyed into the interior of the housing 6 by the climbing conveyor 1, the second motor 62 will start and drive the crushing roller 63 to rotate through belt transmission. At the same time, the crushing roller 63 will drive the circular plate 65 to rotate through the belt. When the second motor 62 rotates, it will drive the support arm 64 to swing reciprocally along the contour of the circular plate 65 through the cooperation relationship between the crank pin on the surface and the chute on the surface of the support arm 64. When the support arm 64 swings, it will drive the pressing plate 66 to move reciprocally along the housing 6. At this time, the waste inside the housing 6 will be continuously pushed between the crushing roller 63 and the pressing plate 66 and crushed by the rotating crushing roller 63 as the pressing plate 66 moves reciprocally. The waste on the surface of the pressing plate 66 will also slide down to the inner wall of the housing 6 and be pushed to the crushing roller 63 by the pressing plate 66 during the reciprocating movement of the pressing plate 66, thereby realizing the uniform crushing of the waste inside the housing 6. At the same time, by setting the filter screen 67, it can also ensure that the waste that has not been completely crushed will be intercepted, thereby increasing the contact area between the waste and the crushing roller 63; when the crushing roller 63 crushes the waste, due to the extrusion and shearing action, dust exhaust gas will be generated inside the housing 6. At this time, the centrifugal fan 7 can be started to absorb these exhaust gases and transport them to the dust removal box 72. The centrifugal fan 7 is a mature existing technology, so its internal structure diagram is not shown. The exhaust gas will pass through the filter bag 74 under the action of positive pressure. The filter bag 74 will filter the dust in the exhaust gas. At the same time, the reciprocally swinging support arm 64 will drive the rotating shaft 75 to swing reciprocally through belt transmission, so that the rotating shaft 75 can drive the plate member 76 to repeatedly strike the filter bag 74, so that the dust attached to the inner wall of the filter bag 74 will fall off and be redistributed, reducing the dust accumulated on the inner wall of the filter bag 74. The air after dust removal can be discharged through the exhaust pipe 73. It is worth mentioning that the installation method of the filter bag 74 can refer to the bag type dust collector in the existing technology;After repeated flapping of the plate member 76, most of the dust on the inner wall of the filter bag 74 will accumulate in the bottom area of the filter bag 74. These dusts will fall into the interior of the storage box 82 through the connecting portion 8. The staff can remove the dust stored in the storage box 82 by removing the maintenance plate on one side of the dust removal box 72 and rotating the storage box 82, so as to quickly discharge the dust in the filter bag 74, and then simplify the operation that the device needs to disassemble the filter bag 74 additionally; the plastic debris crushed by the crushing roller 63 will fall into the interior of the box body 9 through the filter screen 67. At this time, the filter plate 92 will screen the debris again. The debris with smaller particle size will enter a chamber in the box body 9 through the filter plate 92 and can be reduced from local accumulation under the guiding action of the inclined surface of the chute 93, while the debris with larger particle size will enter another chamber through the filter plate 92, realizing the screening of the debris by the device, so as to facilitate the use of the debris by the device; by arranging the partition plate 1001 and the guiding plate 1002, the falling debris in the chamber can be guided and separated, so that these debris can be more evenly distributed in the cavity formed by the partition plate 1001, further reducing the situation of local accumulation of debris in the chamber of the box body 9, and thus reducing the situation of debris overflow in the box body 9.
