DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1-8 As shown, the present invention has the following specific embodiments.

[0034] Example 1

[0035] A recycling and processing device for waste plastics, comprising: a cleaning tank 1, wherein the inner walls on both sides of the cleaning tank 1 are fixedly connected with second flanges 102 near the upper end, the inner walls on both sides of the cleaning tank 1 are fixedly connected with first flanges 101 below the second flanges 102, and the first flanges 101 have three upper and lower staggered distributions, and a collecting tank 5 is symmetrically opened on one side of the cleaning tank 1, and a collecting box 501 is slidably installed in the collecting tank 5;

[0036] The cleaning mechanism 3 includes a conveyor belt 301 and a cleaning cylinder 304. The inner roller of the conveyor belt 301 is rotatably connected to the inner wall of the cleaning tank 1. The inner wall of the cleaning cylinder 304 is fixed with a spiral blade 310.

[0037] The cleaning cylinder 304 includes a connecting cylinder 306 and a plurality of bearing rings 305. The bearing rings 305 are rotatably connected to the connecting cylinder 306. A fixing seat 307 is fixedly connected below the bearing ring 305. The fixing seat 307 is fixedly connected to the conveyor belt 301. Cleaning screen cylinders 308 are fixedly connected to both ends of the connecting cylinder 306. A rubber anti-slip ring 311 is fixedly connected to the cleaning screen cylinder 308 near the edge of the other end.

[0038] The feeding mechanism 2 is used to feed the cleaning cylinder 304 .

[0039] In this embodiment, the plastic fragments can be inserted into the cleaning cylinder 304 through the feeding mechanism 2, and the cleaning cylinder 304 can be driven to rotate through the conveyor belt 301. The two ends of the cleaning cylinder 304 are in contact with the inner wall of the cleaning tank 1, so that the two ends of the cleaning cylinder 304 are blocked to prevent the plastic fragments from overflowing when the cleaning cylinder 304 moves. A certain amount of rinse agent is added to the cleaning tank 1, and the water level needs to just submerge the conveyor belt 301. At this time, when the cleaning cylinder 304 is driven by the conveyor belt 301 to move downward, the cleaning cylinder 304 will be completely submerged in the rinse agent, and the rubber anti-slip ring 31 1 will contact with the first convex edge 101 and the second convex edge 102, so that when the cleaning cylinder 304 moves, it will use friction to drive itself to rotate, thereby driving the internal plastic fragments to rotate and fully rinse the plastic fragments. When the cleaning cylinder 304 is below the conveyor belt 301, it will first contact with the first convex edge 101. There are three groups of first convex edges 101, two of which are of the same height, and one is located above between the two first convex edges 101 below. The upper and lower first convex edges 101 are respectively in contact with the upper and lower surfaces of the rubber anti-slip ring 311, which will drive the cleaning cylinder 304 to rotate in different directions. In the process of moving the cleaning cylinder 304 forward, the shaking plastic fragments inside effectively rinse the garbage on the plastic fragments. When the cleaning cylinder 304 rotates from the other end to the top of the conveyor belt 301, it will contact the second convex edge 102. The second convex edge 102 is in the shape of a long strip and always contacts the rubber anti-skid ring 311. At this time, the cleaning cylinder 304 rotates in one direction. The rotation of the cleaning cylinder 304 will drive the internal spiral blade 310 to rotate. The rotation of the spiral blade 310 will drive the plastic fragments inside the cleaning cylinder 304 to move to one end. When the cleaning cylinder 304 moves to the discharge port 109, The end of the cleaning cylinder 304 will lose the inner wall seal of the cleaning tank 1 on one side. At this time, the plastic crushed pieces inside the cleaning cylinder 304 will be transported through the discharge port 109 and discharged from the cleaning cylinder 304 from the discharge port 109 to complete the cleaning of the plastic crushed pieces. The rinsing cage composed of the cleaning cylinder 304 can make the plastic crushed pieces completely immersed in the rinsing agent, which is suitable for all kinds of plastic crushed pieces. At the same time, under the drive of the conveyor belt 301, the cleaning cylinder 304 reciprocates, and the plastic crushed pieces can be continuously added through the feeding mechanism 2 into different cleaning cylinders 304 for cleaning, and the processing efficiency is high.

[0040] Example 2

[0041] like Figure 1 , 3 As shown, a discharge port 109 is provided at the upper edge of one side of the cleaning tank 1, a discharge ramp 103 is fixedly connected to the discharge port 109, a stepper motor 108 is fixedly connected to one side of the cleaning tank 1, the stepper motor 108 is fixedly connected to the driving roller of the conveyor belt 301, a drying fan 4 is fixedly connected to one side of the cleaning tank 1 through an installation support seat 104, two ventilation slots 105 are provided on one side of the cleaning tank 1, the output end of the drying fan 4 is connected to the ventilation slot 105 through a duckbill head, an exhaust slot 107 is provided on the other side of the cleaning tank 1, the exhaust slot 107 is opposite to one of the ventilation slots 105, a ventilation filter is fixedly connected to the inner wall of the cleaning tank 1 in the ventilation slot 105, a heating wire 106 is fixedly connected to the center of the ventilation slot 105, and ventilation filters are fixedly connected to the edges of both ends of the exhaust slot 107.

[0042] In this embodiment, one end of the cleaning cylinder 304 can be exposed through the discharge port 109, so that the cleaned plastic fragments can be dumped onto the discharge ramp 103. A collection frame or a conveyor belt can be placed under the discharge ramp 103 to collect the cleaned plastic fragments. The drying fan 4 can be started to blow air into the ventilation slot 105. The heating wire 106 heats the air passing through the ventilation slot 105. One ventilation slot 105 is aligned with the exhaust slot 107, and the other ventilation slot 105 is aligned with the discharge port 109, so that the heated air can pass through the interior of the cleaning tank 1 horizontally. Hot air is blown into the cleaning cylinder 304 passing through, so as to preliminarily dry the plastic fragments inside the cleaning cylinder 304, and prevent the large amount of moisture contained in the plastic fragments after cleaning from sticking to the inner wall of the cleaning cylinder 304. At the same time, the air is blown toward the discharge port 109, which can assist in blowing the plastic fragments inside the cleaning cylinder 304 toward the discharge port 109, and assist in discharging the plastic fragments from the cleaning cylinder 304. The exhaust slot 107 is mainly used to prevent the plastic fragments from entering the exhaust slot 107 and the ventilation slot 105, and replaces the inner wall of the cleaning slot 1 to seal the two ends of the cleaning cylinder 304.

[0043] Example 3

[0044] like Figure 1 , 2As shown in , 4, the feeding mechanism 2 includes a feeding hopper 201 and a pushing rod 205. A storage tank 202 is provided in the feeding hopper 201, and the pushing rod 205 is slidably installed in the storage tank 202. A through hole is provided on the inner wall of the cleaning tank 1, and the through hole is communicated with the interior of the storage tank 202. A driving motor 203 is fixedly connected to one side of the feeding hopper 201, and a threaded rod 204 is fixedly connected to the output end of the driving motor 203. A threaded connection hole 206 is provided at one end of the pushing rod 205, and the threaded connection hole 206 is threadedly matched with the threaded rod 204. A limiting slider 207 is provided at the bottom of the feeding hopper 201, and a limiting slide groove 208 is fixedly connected to the bottom of the pushing rod 205, and the limiting slide groove 208 is slidably matched with the limiting slider 207.

[0045] The push rod 205 moves along the bottom of the storage tank 202, and the plastic crushing pieces are pushed through the through hole into the cleaning cylinder 304. At this time, the push rod 205 is completely horizontal at the bottom of the storage tank 202 to prevent the plastic crushing pieces above from falling. When the drive motor 203 is started in the reverse direction to drive the push rod 205 to reset, the plastic crushing pieces in the storage tank 202 are no longer blocked by the push rod 205. The broken pieces of material will fall and fill the holes at the bottom of the hole, and then the stepper motor 108 is started to drive the conveyor belt 301 to rotate. The rotation of the conveyor belt 301 will drive the cleaning cylinder 304 to move. After the other cleaning cylinder 304 is moved to align with the through hole, the stepper motor 108 stops, and the length between the cleaning cylinders 304 is set to a step distance. A single start of the stepper motor 108 will only drive the conveyor belt 301 to rotate a step distance, so that when the stepper motor 108 drives the conveyor belt 301 to rotate, one cleaning cylinder 304 leaves, and the cleaning cylinder 304 at the rear will move back to the original position of the cleaning cylinder 304 in front and realign with the through hole. Repeat the above operation to continuously fill the broken pieces of plastic into the cleaning cylinder 304.

[0046] Example 4

[0047] like Figure 1 , 5 As shown in , 7 and 8, a connecting rod 302 is fixedly connected on the conveyor belt 301 and located between the cleaning cylinders 304, a scraper 303 is fixedly connected to the other end of the connecting rod 302, the scraper 303 is in contact with the bottom of the cleaning tank 1, a screen 309 is embedded and installed on the cleaning screen cylinder 308, a handle 502 is fixedly connected to one side of the collecting box 501, a fixing foot 503 is fixedly connected to the collecting box 501, a threaded hole is opened on one side of the cleaning tank 1 and located above the collecting tank 5, a fixing bolt 504 is arranged in the fixing foot 503, and the fixing bolt 504 cooperates with the threaded hole.

[0048] In this embodiment, the conveyor belt 301 can drive the cleaning cylinder 304 and the connecting rod 302 to rotate synchronously. The rotation of the connecting rod 302 will drive the scraper 303 to rotate. When the scraper 303 rotates to the bottom of the conveyor belt 301, its bottom will contact the bottom of the cleaning tank 1. Therefore, during the movement of the cleaning cylinder 304, the mud and sand deposited at the bottom of the cleaning tank 1 will be scraped into the collection box 501. The cleaning cylinder 304 is driven by the conveyor belt 301 to circulate continuously, so that the impurities deposited at the bottom of the cleaning tank 1 are scraped into the collection box 501. The impurities are continuously collected through the collecting box 501. There are two collecting tanks 5 and collecting boxes 501. The collecting box 501 arranged at the front end will not have any impurities scraped in. It is mainly used to collect impurities at the front end of the bottom of the cleaning tank 1 where the scraper 303 cannot touch. After a certain period of time, it is necessary to unscrew the fixing bolt 504 that fixes the collecting box 501, and pull out the collecting box 501 through the handle 502, and then the collected impurities are concentratedly processed, and 509 allows the rinsing agent to enter the inside of the cleaning cylinder 304, while discharging impurities such as mud and sand.

[0049] The working principle and use process of the present invention are as follows: when in use, a certain amount of rinsing agent needs to be added to the cleaning tank 1, and the height of the rinsing agent can be slightly submerged in the lower end of the conveyor belt 301, and then the plastic crushed pieces to be cleaned are added to the upper hopper 201, and the driving motor 203 is started to drive the push rod 205 to move. The movement of the push rod 205 will fill some of the plastic crushed pieces at the bottom of the storage tank 202 into the cleaning cylinder 304 through the through hole, and the stepping motor 108 is started to drive the conveyor belt 301 to rotate, and the rotation of the conveyor belt 301 will drive the front of the cleaning cylinder 304 The cleaning cylinder 304 is moved by one step, so that another cleaning cylinder 304 is aligned with the through hole, and the above operation is repeated to continuously load several cleaning cylinders 304, and the cleaning cylinder 304 moved down to the bottom of the conveyor belt 301 will be completely immersed in the rinse agent, and at the same time, the rubber anti-skid ring 311 is in contact with the first convex edge 101, and when the cleaning cylinder 304 moves, it will drive itself to rotate continuously, thereby driving the internal plastic fragments to shake, so that the plastic fragments can be fully washed, and at the same time, the rotation of the conveyor belt 301 will drive the scraper 303 to move, and the movement of the scraper 303 will The deposited impurities at the bottom of the cleaning tank 1 are scraped off to the inside of the collection box 501. When the cleaning cylinder 304 carrying the plastic fragments rotates to the top of the conveyor belt 301, the drying fan 4 is started to blow air into the ventilation slot 105. After being heated by the heating wire 106, the air passes through the cleaning cylinder 304, thereby preliminarily drying the cleaned plastic fragments. At the same time, the rubber anti-slip ring 311 will contact the second convex edge 102, which will drive the cleaning cylinder 304 to rotate in one direction. The rotation of the cleaning cylinder 304 will drive the spiral blade 310 to rotate. 310 will convey the internal plastic fragments to one end of the cleaning cylinder 304. When the cleaning cylinder 304 passes through the discharge port 109, the inner wall of the cleaning tank 1 is no longer blocked. At this time, the plastic fragments will be conveyed to the top of the discharge ramp 103. A collection device is placed below the discharge ramp 103. The discharge ramp 103 is inclined, so that the plastic fragments will fall into the placed collection device. The emptied cleaning cylinder 304 will move to a position aligned with the through hole again, and will be filled with a certain amount of plastic fragments for cleaning again, thereby continuously cleaning the plastic fragments.
