Description
Technical Field
[0001] This invention relates to the field of waste recycling, specifically a device for recycling and processing waste from plastic production. Background Technology
[0002] Plastic waste refers to plastic products that have lost their original use value or have not lost their use value but have been discarded during the production, processing and use process. It covers various plastic products such as plastic packaging materials, plastic containers, plastic parts, and plastic films.
[0003] Recycling solid waste such as plastic waste can reduce soil pollution and hinder plant root growth caused by plastic particles, thus playing a role in environmental protection. At the same time, after sorting, cleaning, and crushing, recycled plastics can be directly used as raw materials to produce some plastic products with low quality requirements, such as plastic trash cans and plastic pallets.
[0004] In existing technologies, plastic waste is often directly crushed. However, during use and observation, it has been found that plastic waste contains iron impurities. These iron impurities increase the hardness of the material, which in turn exacerbates the wear of the crushing rollers during operation and shortens the service life of the equipment.
[0005] Therefore, a plastic production waste recycling and processing device is proposed to address the above problems. Summary of the Invention
[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A plastic production waste recycling and processing device according to this invention includes a conveying component, an iron removal component, a crushing component, and a collection component; the conveying component includes an inclined conveyor; the inclined conveyor is used to lift and convey plastic waste; the iron removal component includes an equipment box; a magnet is installed 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 frame is fixedly connected to the output end of the cylinder; positioning rods are symmetrically fixed to both sides of the equipment box; the mounting frame and the positioning rods are through-type and slidably connected; A base plate is fixed to the bottom of the mounting frame, and multiple grooves are formed 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 from the bottom of the base plate. The crushing component is used to crush plastic waste. The collection component is used to recycle the crushed plastic fragments. By setting up the equipment box, iron impurities at the bottom of the base plate can be desorbed, thereby realizing the removal of iron impurities from the waste material by the device, which facilitates the subsequent crushing of the waste material by the device. At the same time, the iron impurities can be desorbed from the base plate by starting the cylinder, realizing the rapid desorption of iron impurities by the device.
[0008] Preferably, the column is provided with a slide rail on its exterior, and the column and the slide rail are slidably connected; a worm gear is rotatably connected to the inner wall of the slide rail; a worm wheel is rotatably connected to the inside of the slide rail; the worm gear and the worm wheel are meshed; a screw is fixedly connected to the top of the worm wheel; the screw and the column are threadedly connected; by rotating the worm gear and the worm wheel, the height of the iron removal component can be adjusted to adapt to the accumulation height of the material on the surface of the inclined conveyor, thereby improving the adsorption effect of the magnet inside the equipment box on iron impurities in the waste.
[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 is fixedly connected to the output end of the first motor, and the pipe and the connecting frame are rotatably connected; the pipe and the air extraction end are in communication and rotatably connected; multiple sets of sleeves are provided through the surface of the pipe; a rod is fixedly connected to the inner wall of the pipe; multiple connecting plates are fixedly connected to the outer wall of the rod; the connecting plates and grooves are correspondingly arranged, and each set of sleeves and connecting plates are correspondingly arranged; a sealing assembly is provided between the sleeves and the connecting plates; the sealing assembly is used to seal the sleeves located at the bottom; a cleanup assembly is provided at the end of the sleeves; the cleanup assembly is used to intercept iron impurities; when desorbing iron impurities at the bottom of the bottom plate, the first motor can be started and the air extraction end connected to the vacuum pump. When the vacuum pump and the first motor start, the pipe fittings will rotate. Due to the rotational connection between the suction end and the pipe fittings, the pipes between the vacuum pump and the suction end will not become entangled. At the same time, the inside of the pipe fittings and the sleeve will be under negative pressure. Under the action of negative pressure, after the cylinder starts, it will drive the base plate to slide on the top of the pipe fittings. The sleeve at the top will be forced to desorb the inner wall of the groove at the bottom of the base plate under the action of negative pressure, thereby reducing the iron impurities adhering to the inner wall of the groove. At the same time, due to the interception effect of the impurity removal component, the iron impurities will not reach the vacuum pump through the pipes. As the pipe fittings rotate, when the sleeve with iron impurities is rotated to the lowest position, the sealing component can seal the sleeve and isolate the airflow. At this time, the iron impurities will fall into the collection box under the action of gravity, realizing the forced desorption of iron impurities in the groove and improving the smoothness of the inner wall of the base plate during desorption.
[0010] Preferably, the sealing 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 to a plug, and the outer wall and end of the plug are multi-holeed; the plug and the sleeve are slidably connected; when the sleeve is at its lowest point, the plug will pull the spring under the action of gravity and put the spring in a stretched state. At this time, the holes on the surface of the spring will be inside the sleeve, so that the bottom sleeve will be in a closed state, while the holes on the surface of the plug at other positions of the sleeve will be exposed, so that the sleeve can maintain a negative pressure state to adsorb iron impurities, thereby realizing the forced desorption of iron impurities inside the groove and improving the cleaning effect when the bottom plate is desorbed.
[0011] Preferably, the impurity removal component includes a suction nozzle; the suction nozzle and the sleeve are threadedly connected; a filter pad is detachably connected to the inner wall of the suction nozzle; by setting the suction nozzle, the opening shape of the nozzle end can roughly adapt to and cover the inner wall area of the groove, thereby ensuring the desorption effect of the sleeve end on the inner wall of the groove, and the filter pad can intercept iron impurities. At the same time, the filter pad and the suction nozzle can be connected by a compression spring, which facilitates the replacement of the filter pad. Since the suction nozzle and the sleeve are threadedly connected, different suction nozzles can be selected according to the groove with different inner wall sizes, improving the flexibility of the device when forcibly desorbing from 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 fitted between the output end of the second motor and the second motor; a pressure plate is slidably connected through the inner wall of the housing; crushing teeth are provided at the end of the pressure plate; support arms are rotatably connected to both sides of the pressure 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 fitted between the circular plate and the crushing roller; a groove is formed on the surface of the support arm, and the groove on the surface of the support 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 transported to the interior of the housing by the inclined conveyor, the second motor will start. The motor drives the crushing roller to rotate via belt drive. Simultaneously, the crushing roller drives the circular plate to rotate via the belt. When the second motor rotates, it drives the support arm to swing back and forth along the contour of the circular plate through the cooperation of the crank pin on the surface and the sliding groove on the surface of the support arm. When the support arm swings, it drives the pressure plate to move back and forth along the shell. At this time, the waste in the shell is continuously pushed between the crushing roller and the pressure plate as the pressure plate moves back and forth, and is crushed by the rotating crushing roller. The waste on the surface of the pressure plate also slides down to the inner wall of the shell during the reciprocating movement of the pressure plate and is pushed to the crushing roller by the pressure plate. This achieves uniform crushing of the waste in the shell. At the same time, by setting a filter screen, it can also ensure that the waste that is not completely crushed is intercepted, thereby increasing the contact area between the waste and the crushing roller.
[0013] Preferably, a centrifugal fan is fixedly installed on the top of the housing; the input end of the centrifugal fan is connected to the top of the housing via a pipe; the output end of the centrifugal fan is connected to a dust collector via a pipe; an exhaust pipe is connected to one side of the dust collector; filter bags are provided inside the dust collector; a rotating shaft is rotatably connected to one side of the dust collector; a plate is fixedly connected to the rotating shaft inside the dust collector; a belt is fitted between the rotating shaft and a side support arm; when the crushing roller crushes the waste material, dust and exhaust gas are generated inside the housing due to the squeezing and shearing action. At this time, the centrifugal fan can be started to remove these waste gases. The gas is absorbed and transported to the dust collection box. The centrifugal fan is a mature existing technology, so its internal structure is not shown in the diagram. The exhaust gas passes through the filter bag under positive pressure. The filter bag filters the dust in the exhaust gas. At the same time, the reciprocating support arm drives the rotating shaft to reciprocate through belt drive. This causes the rotating shaft to repeatedly strike the filter bag with plates, which shakes off and redistributes the dust adhering to the inner wall of the filter bag, reducing the dust accumulation on the inner wall of the filter bag. The dust-collected air can be discharged through the exhaust pipe. It is worth mentioning that the filter bag installation method can refer to the existing bag filter dust collector technology.
[0014] Preferably, the bottom of the filter bag is fixedly connected to a connecting part; the bottom of the connecting part is threadedly connected to a storage box; after repeated beating by the plate, most of the dust on the inner wall of the filter bag will be concentrated in the bottom area of the filter bag. This dust will enter the storage box through the connecting part. The operator can remove the dust stored in the storage box by disassembling the inspection plate on one side of the dust collector and rotating the storage box, so as to quickly discharge the dust in the filter bag and simplify the operation of the device that requires additional disassembly of the filter bag.
[0015] Preferably, the collection assembly 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 and the bottom of the filter plate are fixedly connected; the plastic debris crushed by the crushing roller falls into the interior of the box body through the filter screen, at which time the filter plate will screen the debris again. The smaller debris will enter one chamber of the box body through the filter plate and can reduce local accumulation under the guidance of the inclined surface of the chute, while the larger debris will enter another chamber through the filter plate, realizing the screening of debris by the device, thereby facilitating the use of debris by the device.
[0016] Preferably, multiple partitions are fixedly connected to the bottom of the inner wall of the box and the surface of the chute; guide plates are fixedly connected to the ends of the partitions; by setting partitions and guide plates, the debris falling into the cavity can be guided and separated, so that the debris can be evenly distributed in the cavity formed by the partitions, further reducing the local accumulation of debris in the inner cavity of the box, thereby reducing the overflow of debris from the box.
[0017] The advantages of this invention are:
[0018] 1. The plastic production waste recycling and processing device of the present invention can desorb iron impurities at the bottom of the bottom plate by setting up the equipment box, thereby realizing the removal of iron impurities in the waste and facilitating the subsequent crushing of the waste. At the same time, the bottom plate can be driven to desorb iron impurities by starting the cylinder, realizing the rapid desorption of iron impurities by the device.
[0019] 2. The plastic production waste recycling and processing device of the present invention can adjust the height of the iron removal component by rotating the worm and worm wheel to adapt to the accumulation height of the material on the surface of the inclined conveyor, thereby improving the adsorption effect of the magnet in the equipment box on iron impurities in the waste.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0035] Specific implementation examples are given below.
[0036] Please see Figures 1 to 12 As shown in the embodiment of the present invention, a plastic production waste recycling and processing device includes a conveying component, an iron removal component, a crushing component, and a collecting component. The conveying component includes an inclined conveyor 1, which is used to lift and convey plastic waste. The iron removal component includes an equipment box 12, which contains a magnet. 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. A mounting frame 16 is fixedly connected to the output end of the cylinder 14. Positioning rods 15 are symmetrically fixed to both sides of the equipment box 12. The mounting frame 16 and the positioning rods 15 are through-connected and slidably connected. A base plate 17 is fixedly connected to the bottom of the mounting frame 16, and the surface of the base plate 17 has multiple grooves 18. A collecting box 19 is provided on one side of the equipment box 12, and the top of the collecting box 19 is flared. The collecting box 19 is used to collect iron filings from the bottom of the base plate 17. The crushing component is used to crush the plastic waste. The collecting component is used to recycle the crushed plastic fragments.
[0037] During operation, plastic waste can be conveyed to the surface of the inclined conveyor 1 via a conveyor. The inclined conveyor 1 will then lift and transport the waste to the interior of the housing 6. The inclined conveyor 1 is a mature existing technology, so its specific structure will not be described in detail. During the conveying process on the surface of the inclined conveyor 1, the waste will pass through the equipment box 12. Magnets inside the equipment box 12 will attract iron impurities in the waste under magnetic action, causing these iron impurities to be attracted to the bottom of the base plate 17. The bottom of the base plate 17 has multiple grooves 18, which increases the adsorption area. The waste after iron removal will enter the crushing component and be crushed. Finally, the crushed waste fragments will be collected by the collection component. When it is necessary to remove iron impurities from the bottom of the base plate 17, the cylinder 14 can be activated. The mounting bracket 16 is radially controlled, and it slides along the positioning rod 15, causing the base plate 17 to move along the equipment box 12 and approach the collection box 19. As the base plate 17 moves away from the magnet inside the equipment box 12, the iron impurities adsorbed at the bottom of the base plate 17 fall into the collection box 19 under the action of gravity, thus realizing the desorption of iron impurities at the bottom of the base plate 17. It is worth mentioning that the placement of the magnet is a 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 base plate 17 can be desorbed, thereby realizing the removal of iron impurities in the waste material by the device, which facilitates the subsequent crushing treatment of the waste material. At the same time, by starting the cylinder 14, the base plate 17 can be driven to desorb iron impurities, realizing the rapid desorption of iron impurities by the device.
[0038] Please see Figure 3 and Figure 4 As shown, the column 13 is provided with a slide rail 2 on its outside, and the column 13 and the slide rail 2 are slidably connected; a worm gear 22 is rotatably connected to the inner wall of the slide rail 2; a worm wheel 23 is rotatably connected to the inside of the slide rail 2; the worm gear 22 and the worm wheel 23 are meshed; a screw 24 is fixedly connected to the top of the worm wheel 23; the screw 24 and the column 13 are threadedly connected.
[0039] When processing waste materials, the operator can rotate the handle on one side of the worm 22 to drive the worm 22 to rotate. The worm 22 will then mesh with the worm wheel 23, causing the worm wheel 23 to rotate. The worm wheel 23 will then rotate the screw 24, causing the column 13 to slide vertically along the slide rail 2 under the threaded engagement with the screw 24. This allows the column 13 to control the height of the iron removal assembly, adapting it to the height of the waste material on the surface of the inclined conveyor 1. This ensures that the magnets inside the equipment box 12 can effectively attract iron impurities in the waste material. At the same time, the self-locking nature of the meshing between the worm 22 and the worm wheel 23 ensures the stability of the iron removal assembly during operation. By rotating the worm 22 and the worm wheel 23, the height of the iron removal assembly can be adjusted to adapt to the accumulation height of the material on the surface of the inclined conveyor 1, thereby improving the attraction of iron impurities in the waste material by the magnets inside the equipment box 12.
[0040] Please see 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 and the connecting frame 3 are rotatably connected; the pipe fitting 33 and the air extraction end 32 are in communication, and the pipe fitting 33 and the air extraction end 32 are rotatably connected; multiple sets of sleeves 35 are provided 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 and the groove 18 are correspondingly arranged, and each set of sleeves 35 and the connecting plate 37 are correspondingly arranged; a sealing assembly is provided between the sleeves 35 and the connecting plates 37; the sealing assembly is used to seal the sleeves 35 located at the bottom; a cleanup assembly is provided at the end of the sleeves 35; the cleanup assembly is used to intercept iron impurities.
[0041] When desorbing iron impurities at the bottom of the base plate 17, the first motor 34 can be started and the suction end 32 connected to the vacuum pump. After the first motor 34 starts, it will drive the pipe 33 to rotate the sleeve 35. Due to the rotational connection between the suction end 32 and the pipe 33, the pipe between the vacuum pump and the suction end 32 will not be tangled. At the same time, the inside of the pipe 33 and the sleeve 35 will be under negative pressure. Under the action of negative pressure, after the cylinder 14 starts, it will drive the base plate 17 to slide on the top of the pipe 33, while the top sleeve 35 will be under negative pressure. The device forces the desorption of iron impurities from the inner wall of the groove 18 at the bottom of the base plate 17, thereby reducing the amount of iron impurities adhering to the inner wall of the groove 18. At the same time, due to the interception effect of the impurity removal component, the iron impurities will not reach the vacuum pump through the pipe. As the pipe 33 rotates, when the sleeve 35 with iron impurities is rotated to the lowest position, the sealing component can seal the sleeve 35 and isolate the airflow. At this time, the iron impurities will fall into the collection box 19 under the action of gravity, thereby realizing the forced desorption of iron impurities in the groove 18 and improving the smoothness of the inner wall of the base plate 17 during desorption.
[0042] Please see Figure 6 and Figure 7 As shown, the sealing assembly 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 end of the plug 42 are multi-holeed; the plug 42 and the sleeve 35 are slidably connected.
[0043] When the sleeve 35 is at its lowest point, the plug 42 will pull the spring 4 under the action of gravity and put 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, so that the bottom sleeve 35 will be in a closed state, while the holes on the surface of the plug 42 at other positions of the sleeve 35 will be exposed, so that the sleeve 35 can maintain a negative pressure state to adsorb iron impurities, thereby realizing the forced desorption of iron impurities inside the groove 18 and improving the cleaning effect of the bottom plate 17 during desorption.
[0044] Please see Figure 7 As shown, the impurity removal assembly includes a suction nozzle 5; the suction nozzle 5 and the sleeve 35 are threadedly connected; a filter pad 52 is detachably connected to the inner wall of the suction nozzle 5;
[0045] By setting the suction nozzle 5, the opening shape of the end of the suction nozzle 5 can roughly adapt to and cover the inner wall area of the groove 18, thereby ensuring 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 connected by a compression spring, which facilitates the replacement of the filter pad 52. Since the suction nozzle 5 and the sleeve 35 are threaded, different suction nozzles 5 can be selected according to the groove 18 with different inner wall sizes, improving the flexibility of the device when forcibly desorbing from the groove 18.
[0046] Please see Figures 8 to 10 As shown, the crushing assembly includes a housing 6; a second motor 62 is fixedly mounted on the bottom of the housing 6; a crushing roller 63 is rotatably connected to the inner wall of the housing 6; a belt is fitted between the output end of the second motor 62 and the second motor 62; a pressure plate 66 is slidably connected through the inner wall of the housing 6; crushing teeth are provided at the end of the pressure plate 66; support arms 64 are rotatably connected to both sides of the pressure 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 fitted between the circular plate 65 and the crushing roller 63; a sliding groove is opened on the surface of the support arm 64, and the sliding groove 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 is fixedly connected to the housing 6.
[0047] After the plastic waste is conveyed to the interior of the housing 6 by the inclined conveyor 1, the second motor 62 starts and drives the crushing roller 63 to rotate via belt drive. At the same time, the crushing roller 63 drives the circular plate 65 to rotate via the belt. When the second motor 62 rotates, it drives the support arm 64 to swing back and forth along the contour of the circular plate 65 through the cooperation of the crank pin on the surface and the sliding groove on the surface of the support arm 64. When the support arm 64 swings, it drives the pressure plate 66 to move back and forth along the housing 6. At this time, the waste inside the housing 6 is continuously pushed between the crushing roller 63 and the pressure plate 66 as the pressure plate 66 moves back and forth, and is crushed by the rotating crushing roller 63. The waste on the surface of the pressure plate 66 also slides down to the inner wall of the housing 6 during the reciprocating movement of the pressure plate 66 and is pushed to the crushing roller 63 by the pressure plate 66. This achieves 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 is not completely crushed is intercepted, thereby increasing the contact area between the waste and the crushing roller 63.
[0048] Please see Figure 10 and Figure 11 As shown, a centrifugal fan 7 is fixedly installed on the top of the housing 6; the input end of the centrifugal fan 7 is connected to the top of the housing 6 through a pipe; the output end of the centrifugal fan 7 is connected to a dust collector 72 through a pipe; an exhaust pipe 73 is connected to one side of the dust collector 72; a filter bag 74 is provided inside the dust collector 72; a rotating shaft 75 is rotatably connected to one side of the dust collector 72; a plate 76 is fixedly connected to the rotating shaft 75 located inside the dust collector 72; a belt is sleeved between the rotating shaft 75 and a side support arm 64.
[0049] When the crushing roller 63 crushes the waste material, dust and exhaust gas are generated inside the housing 6 due to the squeezing and shearing action. At this time, the centrifugal fan 7 can be started to absorb these exhaust gases and transport them to the dust collection box 72. The centrifugal fan 7 is a mature existing technology, so its internal structure is not shown in the diagram. The exhaust gas will pass through the filter bag 74 under positive pressure. The filter bag 74 will filter the dust in the exhaust gas. At the same time, the reciprocating support arm 64 will drive the rotating shaft 75 to reciprocate through the belt drive. This allows the rotating shaft 75 to repeatedly strike the filter bag 74 with the plate 76, thereby shaking off and redistributing the dust attached to the inner wall of the filter bag 74, reducing the dust accumulation 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 bag filter dust collector.
[0050] Please see Figure 11 As shown, a connecting part 8 is fixedly connected to the bottom of the filter bag 74; a storage box 82 is threadedly connected to the bottom of the connecting part 8.
[0051] After repeated tapping by plate 76, most of the dust on the inner wall of filter bag 74 will concentrate in the bottom area of filter bag 74. This dust will fall into the storage box 82 through the connecting part 8. The operator can remove the dust stored in the storage box 82 by removing the inspection plate on one side of the dust collector 72 and rotating the storage box 82, so as to quickly discharge the dust in the filter bag 74 and simplify the operation of the device that requires additional disassembly of the filter bag 74.
[0052] Please see 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 fixedly connected.
[0053] The plastic debris crushed by the crushing roller 63 falls into the interior of the box 9 through the filter screen 67. At this time, the filter plate 92 will screen the debris again. The smaller debris will enter one chamber of the box 9 through the filter plate 92 and can reduce local accumulation under the guidance of the inclined surface of the chute 93. The larger debris will enter another chamber through the filter plate 92, thus realizing the screening of debris by the device, which facilitates the use of debris by the device.
[0054] Please see Figure 12 As shown, multiple partitions 1001 are fixedly connected to the bottom of the inner wall of the box 9 and the surface of the chute 93; guide plates 1002 are fixedly connected to the ends of the partitions 1001.
[0055] By setting up partition 1001 and guide plate 1002, the falling debris in the cavity can be guided and separated, so that the debris can be evenly distributed in the cavity formed by partition 1001, further reducing the local accumulation of debris in the cavity of box 9, thereby reducing the overflow of debris in box 9.
[0056] Working principle: Plastic waste is conveyed to the surface of the inclined conveyor 1 via a conveyor belt. The inclined conveyor 1 then lifts and conveys the waste into the interior of the housing 6. The inclined conveyor 1 is a mature existing technology, so its specific structure will not be described in detail. During the conveying process on the surface of the inclined conveyor 1, the waste passes through the equipment box 12. Magnets inside the equipment box 12 attract iron impurities in the waste under magnetic action, causing these iron impurities to be attracted to the bottom of the base plate 17. The bottom of the base plate 17 has multiple grooves 18, which increases the adsorption area. The waste after iron removal enters the crushing component and is crushed. Finally, the crushed waste fragments are collected by the collection component. However, it is necessary to remove the iron impurities from the bottom of the base plate 17. During cleaning, the mounting bracket 16 can be radially controlled by activating cylinder 14. The mounting bracket 16 will slide along positioning rod 15, causing the base plate 17 to move along equipment box 12 and approach collection box 19. As the base plate 17 moves and moves away from the magnet inside equipment box 12, the iron impurities adsorbed at the bottom of the base plate 17 will fall into collection box 19 under gravity, thus achieving the desorption of iron impurities at the bottom of the base plate 17. It is worth mentioning that the placement of the magnet is a mature existing technology, so it is not shown in the figure. When processing waste, the operator can drive the worm gear 22 to rotate by turning the handle on one side of the worm gear 22. The worm gear 22 will mesh with the worm wheel 23, causing the worm wheel 23 to rotate. 23 will rotate the screw 24, and the column 13 will slide vertically along the slide rail 2 under the threaded engagement with the screw 24. This allows the column 13 to control the height of the iron removal assembly, adapting it to the height of the waste material on the surface of the inclined conveyor 1. This ensures that the magnet inside the equipment box 12 can effectively attract iron impurities in the waste material. Simultaneously, the self-locking engagement of the worm gear 22 and worm wheel 23 ensures the stability of the iron removal assembly during operation. When desorbing iron impurities at the bottom of the base plate 17, the first motor 34 can be started, and the extraction end 32 can be connected to the vacuum pump. After the first motor 34 starts, it will drive the pipe fitting 33 to rotate the sleeve 35. Due to the rotational connection between the extraction end 32 and the pipe fitting 33, the vacuum pump and the extraction end 34 can rotate. The pipes between ends 32 will not be tangled. At the same time, the inside of the fitting 33 and the sleeve 35 will be under negative pressure. Under the action of negative pressure, after the cylinder 14 is started, it will drive the base plate 17 to slide on the top of the fitting 33. The sleeve 35 at the top will be forced to desorb the inner wall of the groove 18 at the bottom of the base plate 17 under the action of negative pressure, thereby reducing the iron impurities adhering to the inner wall of the groove 18. At the same time, due to the interception effect of the impurity removal component, the iron impurities will not reach the vacuum pump through the pipe. As the fitting 33 rotates, when the sleeve 35 with iron impurities is rotated to the lowest position, the sealing component can seal the sleeve 35 and isolate the airflow. At this time, the iron impurities will fall into the collection box 19 under the action of gravity, realizing the forced desorption of iron impurities in the groove 18 by the device.When the sleeve 35 is at its lowest point, the plug 42 will pull the spring 4 under gravity, putting 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, making the bottom sleeve 35 closed, while the holes on the surface of the plug 42 at other positions of the sleeve 35 will be exposed. This allows the sleeve 35 to maintain a negative pressure state to adsorb iron impurities, thereby achieving forced desorption of iron impurities inside the groove 18 and improving the cleaning effect of the bottom plate 17 during desorption. By setting the suction nozzle 5, the opening shape of the end of the suction nozzle 5 can roughly adapt to and cover the inner wall area of the groove 18, thereby ensuring the desorption effect of the end of the sleeve 35 on the inner wall of the groove 18. Filter pad 52 This allows for the interception of iron impurities. The filter pad 52 and the suction nozzle 5 are connected via a compression spring, facilitating filter pad 52 replacement. Furthermore, since the suction nozzle 5 and the sleeve 35 are threaded, different suction nozzles 5 can be selected based on the different inner wall sizes of the grooves 18, improving the flexibility of the device when forcibly detaching from the grooves 18. After the plastic waste is conveyed to the interior of the housing 6 by the inclined conveyor 1, the second motor 62 starts and drives the crushing roller 63 to rotate via belt drive. Simultaneously, the crushing roller 63 drives the circular plate 65 to rotate via the belt. When the second motor 62 rotates, it drives the support arm 64 to reciprocate along the contour of the circular plate 65 through the engagement of the crank pin on its surface and the sliding groove on the surface of the support arm 64. When the oscillation of roller 64 causes the pressure plate 66 to reciprocate along the housing 6, the waste material inside the housing 6 is continuously pushed between the crushing roller 63 and the pressure plate 66 as the pressure plate 66 reciprocates and is crushed by the rotating crushing roller 63. The waste material on the surface of the pressure plate 66 also slides down to the inner wall of the housing 6 during the reciprocating motion of the pressure plate 66 and is pushed to the crushing roller 63 by the pressure plate 66, thus achieving uniform crushing of the waste material inside the housing 6. Simultaneously, by setting a filter screen 67, it is ensured that incompletely crushed waste material is intercepted, thereby increasing the contact area between the waste material and the crushing roller 63. When the crushing roller 63 crushes the waste material, dust and exhaust gas are generated inside the housing 6 due to the squeezing and shearing action. This can be addressed by starting the filter screen. The centrifugal fan 7 absorbs these exhaust gases and transports them to the dust collection box 72. The centrifugal fan 7 is a mature existing technology, so its internal structure is not shown in the diagram. The exhaust gas passes through the filter bag 74 under positive pressure. The filter bag 74 filters the dust in the exhaust gas. At the same time, the reciprocating support arm 64 drives the rotating shaft 75 to reciprocate through belt drive. This allows the rotating shaft 75 to repeatedly strike the filter bag 74 with the plate 76, thereby shaking off and redistributing the dust attached to the inner wall of the filter bag 74, reducing the dust accumulation 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 bag filter dust collector.After repeated beating by plate 76, most of the dust on the inner wall of filter bag 74 will concentrate in the bottom area of filter bag 74. This dust will fall into the storage box 82 through the connecting part 8. The operator can remove the dust stored in the storage box 82 by removing the inspection plate on one side of the dust collector 72 and rotating the storage box 82, so as to quickly discharge the dust in the filter bag 74 and simplify the operation of the device that requires additional disassembly of the filter bag 74. The plastic debris crushed by crushing roller 63 will fall into the box 9 through filter screen 67. At this time, filter plate 92 will screen the debris again, and the smaller particles will be separated. Debris enters one chamber of the housing 9 through the filter plate 92 and is guided by the inclined surface of the chute 93, reducing local accumulation. Larger debris passes through the filter plate 92 into another chamber, thus screening the debris and facilitating its use. The partition plate 1001 and guide plate 1002 guide and separate the falling debris within the chamber, ensuring even distribution within the cavity formed by the partition plate 1001. This further reduces local accumulation of debris within the housing 9, minimizing debris overflow.
