Description

Technical Field

[0001] The present invention relates to the technical field of plastic recycling equipment, and specifically relates to a waste plastic recycling device. Background Art

[0002] The recycling and reuse of waste plastics is a process of converting them into new resources through steps such as collection, classification, cleaning, and reprocessing. First, after waste plastics are collected by community recycling systems or professional institutions, they are finely classified according to materials (such as PET, HDPE), colors, and uses. Subsequently, impurities are removed through crushing and high-temperature cleaning. Then, they are processed into recycled plastic pellets through melt granulation technology and used to manufacture industrial products such as packaging boxes, pipes, and building materials. Some can be reduced to monomers through chemical decomposition (such as pyrolysis technology) and re-synthesized into plastics. For example, recycled PET bottles can be converted into polyester fibers for clothing production. This process not only reduces the consumption of petroleum resources and landfill pollution but also reduces carbon emissions.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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 making creative efforts belong to the scope of protection of the present invention.

[0021] Embodiment 1: Please refer to Figures 1 to 8 , in the embodiment of the present invention, a waste plastic recycling device includes a cleaning tank 1 for cleaning plastic fragments. A pretreatment component 2 is connected to the side wall of the cleaning tank 1 in a manner of being supported and fixed by a support plate. The pretreatment component 2 includes a processing box 201. A partition plate 202 for separating the processing box 201 into two spaces is fixedly connected inside the processing box 201. The right space is filled with cleaning water. The upper end of the processing box 201 is fixedly connected to a material bin 203 for storing waste plastic through a feeding component 3. The material bin 203 is rotatably connected with two rubbing pipes 204 through a feeding valve housing 301 in the feeding component 3 with mechanical seal. The outer layers of the two rubbing pipes 204 are made of rubber material, and a layer of plush material is fixed on the inner side thereof. When the rubbing pipes 204 are rubbed, the plush inside the rubbing pipes 204 continuously scrubs the plastic fragments inside, and at the same time, it will also drive multiple plastic fragments to rub against each other under the action of friction, helping the dirt on the surface of the plastic fragments to quickly fall off. The lower ends of the two rubbing pipes 204 are fixedly connected to a discharging component 5 for discharging the rubbed plastic fragments. A rubbing component 4 for rubbing the rubbing pipes 204 is slidably connected inside the processing box 201; The scrubbing assembly 4 includes two scrubbing boxes 401 that are horizontally slidably connected between the front and rear inner walls of the processing box 201, and the two scrubbing boxes 401 are respectively located on the left and right sides of the scrubbing pipe 204 to facilitate clamping of the scrubbing pipe 204. Between the upper and lower inner walls of the two scrubbing boxes 401, two rotating cylinders 402 are rotatably connected. A guiding belt 403 is sleeved between the two rotating cylinders 402. When the two rotating cylinders 402 rotate, the guiding belt 403 can be driven to move. By clamping the two sides of the scrubbing pipe 204 with the two guiding belts 403 and moving them in different directions, the guiding belt 403 can drive the scrubbing pipe 204 to rub and rotate through friction. Between the upper and lower inner walls of the scrubbing box 401, there is a fixed connection of a resisting block 404 for the guiding belt 403 to resist the guiding belt 403 to prevent it from undergoing large deformation when squeezing the scrubbing pipe 204. A plurality of evenly distributed resistance-reducing columns 405 are rotatably connected to the resisting block 404, and the plurality of resistance-reducing columns 405 are in contact with the guiding belt 403. The resistance-reducing columns 405 can effectively reduce the friction between the resisting block 404 and the guiding belt 403. At the upper ends of the two scrubbing boxes 401, a transmission box 406 is fixedly connected by welding. A worm gear 407 is rotatably connected to the lower inner wall of the transmission box 406, and the axis of the worm gear 407 is fixedly connected to the axis of the rotating cylinder 402.

The thread directions of the two worm gear sleeves 408 are symmetrically arranged, so that when the two worm gear sleeves 408 rotate in the same direction, the two worm gears 407 can be respectively driven to rotate in different directions. A same square rod 409 is inserted between the two worm gear sleeves 408. When the square rod 409 rotates, it simultaneously drives the two worm gear sleeves 408 to rotate, and further enables the two worm gear sleeves 408 to simultaneously drive the two worm gears 407 to rotate respectively. The two ends of the square rod 409 are respectively rotatably connected to the inner side wall of the processing box 201 and the side wall of the partition 202. A driving motor 410 for driving the square rod 409 to rotate is fixedly connected to the side wall of the processing box 201, and the output end of the driving motor 410 is fixedly connected to the square rod 409 by bolts. There is a clamping assembly 6 for driving the scrubbing box 401 to move rotatably connected between the upper linkage rod 304 in the feeding assembly 3 and the lower linkage rod 505 in the discharging assembly 5. A cleaning assembly 7 for pumping and draining water is communicated between the feeding assembly 3 and the discharging assembly 5. A material assisting discharging assembly 8 for discharging materials is communicated with the cleaning assembly 7. A synchronous control assembly 9 for facilitating simultaneous control and adjustment is fixedly connected to the side wall of the processing box 201. Two water replacement pipes 10 for replacing water are inserted into the side wall of the processing box 201.

[0022] The blanking component 3 includes two blanking valve casings 301 that are rotationally connected and communicated with the upper end of the tube rubbing member 204 through mechanical seals, and the upper ends of the two blanking valve casings 301 are communicated with the bottom of the material bin 203. Inside each of the two blanking valve casings 301, a blanking valve core 302 is rotationally connected. A blanking T-shaped cavity 303 is drilled inside the blanking valve core 302. When the blanking valve core 302 rotates to make the blanking T-shaped cavity 303 communicate with the material bin 203, the waste plastic inside the material bin 203 is discharged downward through the blanking valve core 302 into the inside of the tube rubbing member 204. By rotating the blanking valve core 302, the tube rubbing member 204 can also be made to communicate with the first communication pipe 701 in the cleaning component 7. A upper linkage rod 304 is fixedly connected between the two blanking valve cores 302. A handle 305 is rotationally connected to the side wall of the processing box 201, and the handle 305 is fixedly connected to the blanking valve core 302. When the handle 305 is rotated, the two blanking valve cores 302 can be driven to rotate simultaneously. In addition, limiting pieces are provided on both sides of the handle 305, so that the handle 305 can accurately drive the blanking valve core 302 to rotate 90 degrees.

[0023] The discharging component 5 includes two discharging valve casings 501, and the upper ends of the two discharging valve casings 501 are rotationally connected and communicated with the bottom of the tube rubbing member 204 through mechanical seals. Inside each of the two discharging valve casings 501, a discharging valve core 502 is rotationally connected. A discharging T-shaped cavity 503 is drilled inside the discharging valve core 502. When the discharging valve core 502 rotates to make the discharging T-shaped cavity 503 communicate with the discharging pipe 506, the waste plastic inside the tube rubbing member 204 can be discharged downward through the discharging valve core 502 and the discharging pipe 506 into the cleaning pool 1. By rotating the discharging valve core 502, the tube rubbing member 204 can also be made to communicate with the second communication pipe 702 in the cleaning component 7. A filter screen 504 for intercepting plastic fragments is fixedly connected inside the discharging T-shaped cavity 503. When the water pump 705 is started, the cleaning water inside the tube rubbing member 204 can be pumped out, and at the same time, the filter screen 504 intercepts the plastic fragments. A lower linkage rod 505 is fixedly connected between the two discharging valve cores 502. The lower ends of the two discharging valve casings 501 are both communicated with a discharging pipe 506.

[0024] The clamping component 6 includes a magnetic plate 601, and the upper and lower ends of the magnetic plate 601 are respectively rotationally connected to the centers of the upper linkage rod 304 and the lower linkage rod 505 through bearings. An electromagnet is installed inside the magnetic plate 601. Since the abutting blocks 404 are made of iron, the electromagnet generates a suction force on the two side abutting blocks 404 when it is energized. Roller cylinders 602 are rotationally connected to both side walls of the magnetic plate 601. When the magnetic plate 601 is started, the magnetic plate 601 and the abutting blocks 404 are magnetically attracted to each other. A reset spring 603 is fixedly connected between the side walls of the two scrubbing boxes 401 facing away from each other and the processing box 201 and the partition plate 202 respectively.

[0025] The cleaning component 7 includes a first connecting pipe 701 that is connected and fixed to two blanking valve housings 301, and a second connecting pipe 702 that is connected and fixed to two discharging valve housings 501. An air inlet pipe 703 is connected and fixed to the first connecting pipe 701, and a solenoid valve 704 for opening and closing is fixedly connected to the air inlet pipe 703. A water pump 705 for pumping water is fixedly connected to the second connecting pipe 702. When the water pump 705 is started, it can pump the cleaning water in the treatment tank 201 into the rubbing pipe 204 to improve the cleaning effect on plastic fragments, and the cleaned water is discharged back into the treatment tank 201 through the second connecting pipe 702 again, achieving a circulating effect of the cleaning water, reducing water consumption. During this process, when the solenoid valve 704 is opened, the water pump 705 will pump out the water in the rubbing pipe 204, and no more cleaning water will flow into the rubbing pipe 204. Instead, the air entering through the air inlet pipe 703 will replace it.

[0026] Embodiment 2: Please refer to Figures 9 to 10 , on the basis of Embodiment 1, the material assisting discharge component 8 includes a pipe changing valve housing 801 connected to the second connecting pipe 702. A pipe changing valve core 802 is rotatably connected inside the pipe changing valve housing 801. A pipe changing T-shaped cavity 803 is drilled inside the pipe changing valve core 802. A water suction pipe 804 for pumping water is connected and fixed to the lower end of the pipe changing valve housing 801. A filter cylinder 805 for filtering the plastic fragments after rubbing and washing is fixedly connected to the lower end of the water suction pipe 804. A on-off valve housing 806 is connected between the first connecting pipe 701 and the water outlet end of the water pump 705. A on-off valve core 807 is rotatably connected inside the on-off valve housing 806. Two on-off T-shaped cavities 808 are drilled inside the on-off valve core 807, and the two on-off T-shaped cavities 808 are respectively connected to the lower end of the first connecting pipe 701 and the water outlet end of the water pump 705. In the initial state, the water discharged by the water pump 705 is discharged back into the treatment tank 201 through the on-off T-shaped cavity 808, and the first connecting pipe 701 pumps water through the on-off T-shaped cavity 808. When it is necessary to discharge the plastic fragments that have been rubbed and washed in the rubbing pipe 204 for the next cleaning step, through the synchronous control component 9, the on-off valve core 807, the pipe changing valve core 802, and the discharging valve core 502 can be rotated simultaneously, so that the water pump 705 is connected to the first connecting pipe 701, and at the same time, the pipe changing valve core 802 is connected to the water suction pipe 804, and the discharging T-shaped cavity 503 is connected to the discharging pipe 506, changing the entire circulating pipeline. The state at this time is as Figure 8 shown. The water pump 705 extracts fresh and clean water in the cleaning pool 1 through the water suction pipe 804, and through the first connecting pipe 701 and the blanking T-shaped cavity 303, the plastic fragments in the rubbing pipe 204 are carried out by the water flow, so that the plastic fragments can be discharged into the cleaning pool 1 through the discharging T-shaped cavity 503 and the discharging pipe 506, thereby effectively improving the discharging efficiency of the plastic fragments by using the water flow.

[0027] The synchronous control component 9 includes a control box 901 fixedly connected to the side wall of the processing box 201. A plurality of first bevel gears 902 are rotatably connected to the inner side wall of the control box 901. Control rods 903 are fixedly connected between the plurality of first bevel gears 902 and the on-off valve core 807, the pipe-changing valve core 802, and the discharging valve core 502 respectively. The control rods 903 are rotatably connected to the control box 901. A mechanical seal is installed between the control rods 903 and the processing box 201 to prevent the water inside the processing box 201 from leaking. A rotating rod 904 is rotatably connected inside the control box 901. A plurality of second bevel gears 905 meshing with the first bevel gears 902 are fixedly connected to the rotating rod 904. One end of the control box 901 is fixedly connected with an adjusting motor 906, and the output end of the adjusting motor 906 is fixedly connected to the rotating rod 904. When discharging, only need to start the adjusting motor 906, so that the adjusting motor 906 drives a plurality of first bevel gears 902 to rotate synchronously through the rotating rod 904 and a plurality of second bevel gears 905, so as to respectively and simultaneously drive the discharging valve core 502, the pipe-changing valve core 802, and the on-off valve core 807, so as to quickly switch to the discharging state.

[0028] The working principle of the present invention is as follows: When the present invention is in use, first, the staff first puts the sorted waste plastics into the inner part of the material bin 203, and then rotates the rotating handle 305. When the feeding valve core 302 rotates to connect the feeding T-shaped cavity 303 with the material bin 203, the waste plastics inside the material bin 203 are discharged downward through the feeding valve core 302 into the inner part of the rubbing pipe 204. After the inner part of the rubbing pipe 204 is filled, rotate the rotating handle 305 again to close the feeding channel. Then start the electromagnet inside the magnetic plate 601, so that it can simultaneously adsorb the abutting blocks 404 on both sides. The abutting blocks 404 drive the rubbing boxes 401 on both sides to approach each other until the guiding belt 403 exerts an extrusion effect on the rubbing pipe 204. At this time, start the driving motor 410. The driving motor 410 drives the square rod 409 to rotate, so that the square rod 409 simultaneously drives two worm sleeves 408 to rotate, and then the two worm sleeves 408 can simultaneously drive two worm wheels 407 to rotate respectively. Since the thread directions of the two worm sleeves 408 are symmetrically arranged, when the two worm sleeves 408 rotate in the same direction, they can drive the two worm wheels 407 to rotate in different directions respectively. Therefore, when the worm wheel 407 drives the rotating cylinder 402 to rotate, the rotating cylinder 402 drives the guiding belt 403 to move. By clamping the two sides of the rubbing pipe 204 with the two guiding belts 403 and moving in different directions, the guiding belt 403 can drive the rubbing pipe 204 to rub and rotate through friction. When the rubbing pipe 204 is rubbed, the plush inside the rubbing pipe 204 continuously scrubs the plastic fragments inside it, and at the same time, it will also drive a plurality of plastic fragments to rub against each other under the action of friction, helping the dirt on the surface of the plastic fragments to fall off quickly; While scrubbing the plastic fragments, the staff can also start the water pump 705. The water discharged by the water pump 705 is returned to the treatment tank 201 through the on-off T-shaped cavity 808. The first connecting pipe 701 pumps water through the on-off T-shaped cavity 808. The water pump 705 pumps the cleaning water in the treatment tank 201 into the scrubbing pipe 204 through the first connecting pipe 701 to improve the cleaning effect on the plastic fragments, and then returns the cleaned water to the treatment tank 201 through the second connecting pipe 702, achieving the recycling effect of the cleaning water. This method not only uses water to reduce the adhesion of dirt and make it easier to fall off, but also reduces the water consumption. When the scrubbing stage of the plastic fragments ends, when the staff opens the solenoid valve 704, the water pump 705 will pump out the water in the scrubbing pipe 204, and no more cleaning water will flow into the scrubbing pipe 204. Instead, air enters through the air inlet pipe 703. In this way, the water used for flushing in the scrubbing pipe 204 can be completely drained. Finally, the staff only needs to start the adjustment motor 906, so that the adjustment motor 906 drives the plurality of first bevel gears 902 to rotate synchronously through the rotating rod 904 and the plurality of second bevel gears 905 at the same time, achieving the purpose of simultaneously driving the discharge valve core 502, the pipe-changing valve core 802 and the on-off valve core 807 respectively, as Figure 10 shown, so as to quickly switch to the discharging state. At this time, the water pump 705 pumps the water in the cleaning pool 1 through the water suction pipe 804, and through the first connecting pipe 701 and the blanking T-shaped cavity 303, and uses the water flow to take out the plastic fragments in the scrubbing pipe 204, so that the plastic fragments can be discharged to the cleaning pool 1 through the discharge T-shaped cavity 503 and the discharge pipe 506. This can not only prevent the water previously flushed from polluting the water in the cleaning pool 1, but also effectively improve the discharging efficiency of the plastic fragments by using the water flow.

[0029] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
