Description

Technical Field

[0001] This invention belongs to the field of crushing and cleaning technology, specifically relating to a washing and crushing equipment for waste plastic recycling. Background Technology

[0002] Every year, a large number of plastic bottles and other plastic products are generated in our daily lives and need to be recycled to avoid environmental pollution. Plastic recycling refers to the process of recycling waste plastics to make them usable again and turn waste into treasure. After recycling, waste plastics generally need to be cleaned and crushed to provide clean raw materials for subsequent processes such as melting and granulation.

[0003] Patent publication number CN207657011U discloses a crushing and washing device for recycling waste plastics, including a base and a collection box. A conveyor belt support is welded to one side of the top outer wall of the base, and a drive wheel and a driven wheel are connected to the top inner wall of the conveyor belt support via bearings. The drive wheel and the driven wheel are fitted with the same conveyor belt, and the drive wheel and the driven wheel form a transmission connection via a transmission belt. A grooved belt is fixed to one side of the outer wall of the transmission belt with screws. A water tank is welded to the top outer wall of the base near the conveyor belt support. This patent's circulating filtration spray device can solve the problem of sewer blockage and facilitates the cleaning of waste. Water resources can be reused, saving costs. The crushing box and collection box allow for pre-crushing followed by grinding, preventing clogging of the crushing device, improving crushing efficiency and equipment lifespan. The conveyor belt with grooves can recycle and clean waste plastics, improving the equipment's cleaning and crushing efficiency.

[0004] However, the device also has shortcomings: while it can improve the cleaning and crushing efficiency of waste plastics during the recycling process, the waste plastics can only come into contact with the water flow and be washed on one side during horizontal conveying. This makes it difficult to achieve comprehensive cleaning, thereby reducing the cleanliness of the waste plastics during crushing and subsequent processing, which can easily increase the difficulty of subsequent cleaning. At the same time, it is difficult to ensure that the waste plastics are dried evenly to avoid embrittlement due to over-drying, and it is difficult to purify the harmful gases generated during the processing of waste plastics, thus reducing the overall practicality of the equipment to a certain extent. Summary of the Invention

[0005] The purpose of this invention is to provide a washing and crushing device for recycling waste plastics, so as to solve the problem mentioned in the background art that waste plastics can only contact and be washed by water flow on one side during horizontal conveying.

[0006] To achieve the above objectives, the present invention provides a washing and crushing equipment for waste plastic recycling, comprising: a main body of the device; a water spraying mechanism is provided on the top left side of the main body; a collection box is provided on the inside left side of the main body; a drying mechanism is provided on the right side of the main body; an electric rotating rod is rotatably installed inside the main body; several telescopic mesh plates are equidistantly and fixedly installed on the outer wall of the electric rotating rod; an inclined plate is fixedly installed on the bottom of the inner wall of the square groove of the collection box; a crushing mechanism is fixedly installed on the bottom of the inner wall of the main body; a vertical pipe is connected to and fixedly installed on the top of the crushing mechanism; a negative pressure mechanism is provided on the top of the main body; the bottom of the negative pressure mechanism is connected to and fixedly installed on the top of the vertical pipe; a conveying mechanism is fixedly installed on the bottom right side of the inner wall of the main body; a conveying pipe is provided inside the conveying mechanism; an anti-brittleness device to ensure uniform drying of the plastic is provided above the conveying pipe; and an anti-pollution device to purify the plastic during drying is provided around the anti-brittleness device.

[0007] In one or more embodiments of the present invention, a reciprocating screw is rotatably mounted inside one end of the back of the device body, an elliptical block is fixedly mounted through and on the outer wall of one end of the front of the reciprocating screw, a scraper frame is slidably mounted on the inner wall of the vertical tube by a spring, a crossbar is fixedly mounted inside the bottom end of the scraper frame, a round wheel is rotatably mounted through and on the outer wall of the crossbar, the output end of the water spraying mechanism is located inside the device body, a square groove is opened on the right side of the collection box, a drain pipe is fixedly mounted through and on the left end of the collection box, the drain pipe is connected to an external water pump, the telescopic end of the telescopic mesh plate contacts the inner side wall of the collection box, the bottom of the inclined plate is located inside the left end of the crushing mechanism, and the left end of the conveying pipe is connected to and fixedly mounted on the right side of the crushing mechanism.

[0008] In one or more embodiments of the present invention, one end of the reciprocating screw is connected to the electric rotary rod via a conveyor belt, and one end of the reciprocating screw extends through the interior of the vertical pipe. The outer wall of the reciprocating screw is a non-self-locking reciprocating spiral groove. The circumferential surface of the wheel contacts the outer wall of the elliptical block. Before the waste plastic enters the collection box through the inclined surface at the left end, the electric rotary rod is activated. When the electric rotary rod rotates, it drives the telescopic mesh plate to revolve. The telescopic end of the telescopic mesh plate is in close contact with the inner wall of the collection box and receives the waste plastic. At the same time, the output end of the water spraying mechanism sprays water to clean the waste plastic. During the revolve of the telescopic mesh plate, dirt and dirty water seep into the collection box through its surface mesh. The collection box removes the dirty water through a drain pipe and an external water pump. After treatment, the dirty water is fed into the water spraying mechanism to achieve water recycling. At the same time, after the telescopic mesh plate revolve, the cleaned wastewater is guided into the crushing mechanism through the inclined plate. The crushing mechanism crushes the wastewater. In this process, the negative pressure mechanism is activated, and it extracts the pulverized waste plastic powder from the inside of the pulverizing mechanism through the vertical pipe. Then, the conveying mechanism is activated, and it feeds the pulverized waste plastic into the drying mechanism through the conveying pipe for drying. The drying mechanism, with the help of external equipment, extracts the dried waste plastic from the drying mechanism. When the electric rotary rod rotates, it drives the reciprocating screw to rotate through the conveyor belt. When the reciprocating screw drives the elliptical block to revolve inside the vertical pipe, the elliptical block expands the flow orifice inside the vertical pipe. At the same time, the elliptical block contacts the outer wall of the rotating wheel. The contact of the elliptical block causes the wheel to generate an upward force. The wheel causes the crossbar and the scraper frame to move synchronously. At this time, the scraper frame scrapes the inner wall of the vertical pipe. When the elliptical block returns to its original position, the flow orifice inside the vertical pipe shrinks again. This process is repeated. When the elliptical block returns to its original position, it releases the contact with the wheel. At this time, the scraper frame returns to its original position by the spring force.

[0009] In one or more embodiments of the present invention, the anti-brittleness device includes a shaped plate, the bottom end of which is penetrated and movably installed on the outer wall of the reciprocating lead screw, a circular groove plate is provided above the top of the shaped plate, the interior of the circular groove plate is located on the top movement trajectory of the shaped plate, and an L-shaped hammer plate is fixedly installed on the right side wall of the circular groove plate.

[0010] In one or more embodiments of the present invention, the top of the irregularly shaped plate is slidably installed inside the top of the device body, and the top of the irregularly shaped plate is designed with an arc surface. The bottom outer wall of the L-shaped hammer plate is slidably installed inside the device body through a spring. The bottom of the L-shaped hammer plate contacts the top inclined surface of the conveying pipe. When the reciprocating screw rotates, it is driven by the non-self-locking reciprocating spiral groove on its outer wall, which causes the irregularly shaped plate to slide horizontally along the inside of the top of the device body. When the irregularly shaped plate slides horizontally, it contacts and abuts the arc surface of the circular groove plate, thereby generating an upward resisting force. At this time, the circular groove plate drives the L-shaped hammer plate to move upward. When the irregularly shaped plate passes over the single arc surface of the circular groove plate, the L-shaped hammer plate, through the spring force, suddenly falls from the upward water-filled state and strikes the top of the conveying pipe to generate vibration. This process is repeated, and under the strike of the L-shaped hammer plate, the conveying pipe is caused to convey waste plastic during the vibration process.

[0011] In one or more embodiments of the present invention, a drive plate is fixedly installed on the right sidewall of the L-shaped hammer plate; a transmission rod is rotatably installed through the bottom of the inner wall of the drying mechanism; both ends of the transmission rod are provided with non-self-locking spiral grooves; the spiral groove at the top of the transmission rod is movably installed inside the drive plate; the spiral groove at the bottom of the transmission rod is movably installed through the drive plate; a heating mechanism is slidably installed on the outer wall of the heating mechanism inside the drying mechanism; and several heat-conducting rods are equidistantly and fixedly installed at the inner edge of the drying mechanism, with the outer walls of the heat-conducting rods movably penetrating the interior of the heating mechanism. The heat-conducting rod is connected to the heating mechanism, and the heat-conducting rod disperses and conducts heat from the heating mechanism. When the L-shaped hammer plate drives the drive plate to move upward, the drive plate slides along the outer wall of the spiral groove of the transmission rod. Relying on the limiting of the non-self-locking spiral groove, the transmission rod generates a rotational force. When the transmission rod rotates, it drives the heating mechanism to slide upward along the inner wall of the drying mechanism through the non-self-locking spiral groove at its bottom. After that, the drive plate resets, and the transmission rod reverses to reset the heating mechanism. When the heating mechanism slides along the outer wall of the heat-conducting rod, it relies on the heat-conducting rod to conduct heat in segments.

[0012] In one or more embodiments of the present invention, the anti-pollution device includes a gear, which is internally penetrated and fixedly installed on the outer wall of the transmission rod. Two racks are symmetrically and slidably installed on the top of the inner wall of the drying mechanism. A sliding frame is fixedly installed on the outer side wall of the racks, and a friction column is rotatably installed inside the sliding frame.

[0013] In one or more embodiments of the present invention, the rack meshes with the gear, the outer wall of the friction column contacts the top of the inner wall of the drying mechanism, the friction column is circular and contains activated carbon particles, the transmission rod drives the gear to rotate, and when the gear rotates, it drives the meshing rack to slide horizontally along the top of the inner wall of the drying mechanism, and the symmetrically arranged racks slide horizontally in opposite directions. The rack drives the sliding frame to move synchronously, and when the sliding frame moves horizontally back and forth, it drives the friction column to move synchronously along the top of the inner wall of the drying mechanism. At this time, the friction column generates friction and rotates inside the sliding frame. When the friction column rotates, it causes the activated carbon gas generated by the activated carbon particles inside to volatilize and diffuse evenly.

[0014] In one or more embodiments of the present invention, an elastic telescopic plate is fixedly installed at the bottom of the rack, and an L-shaped frame is fixedly installed at the bottom of the telescopic end of the elastic telescopic plate. The bottom of the L-shaped frame is slidably installed on the top of the heating mechanism, and a drying mechanism is fixedly installed inside the L-shaped frame. The drying mechanism contains desiccant particles. When the rack moves horizontally, it drives the elastic telescopic plate to move synchronously. The telescopic end of the elastic telescopic plate pulls the L-shaped frame to move synchronously along the top of the heating mechanism. The L-shaped frame drives the drying mechanism to move synchronously. At the same time, the rising heating mechanism raises the height of the drying mechanism, so that the drying mechanism can volatilize dry gas during the horizontal and vertical movement.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: through the cooperation of an electric rotating rod, a telescopic mesh plate, an inclined plate, a crushing mechanism, a vertical pipe, a negative pressure mechanism, a conveying mechanism, a conveying pipe, a reciprocating screw, an elliptical block, a scraper ring, a crossbar, and a wheel, the various mechanisms work together to enable waste plastics to complete an automated washing, crushing, and drying process, saving manpower and improving processing efficiency. Simultaneously, relying on the revolving telescopic mesh plate, comprehensive cleaning of waste plastics is achieved before crushing, unlike the single-sided water rinsing of traditional horizontal conveying, greatly optimizing the cleanliness of waste plastics during processing and avoiding the need for subsequent secondary cleaning due to inadequate cleaning. The revolving elliptical block continuously changes the internal flow orifice diameter of the vertical pipe. As the flow orifice diameter changes from small to large, the internal pressure of the vertical pipe increases, cooperating with the scraping action of the scraper ring to prevent damp plastic powder from adhering to the inner wall surface of the vertical pipe. This optimizes the flow effect of gas and powder inside the vertical pipe, preventing reduced conveying efficiency due to powder adhesion. By incorporating an anti-brittleness device, a combination of a reciprocating screw, shaped plate, circular groove plate, L-shaped hammer plate, drive plate, transmission rod, heating mechanism, and heat-conducting rod is employed. The shaped plate's contact causes the L-shaped hammer plate to reciprocate vertically against the top of the conveying pipe. This vibration keeps the waste plastics transported within the conveying pipe in an independent and loose state as they enter the drying mechanism, preventing them from sticking together due to moisture and reducing drying efficiency. The reciprocating vertical motion of the heating mechanism ensures more even heat distribution to the heat-conducting rod, and the multi-point heat conduction by the rod results in a more balanced heat distribution within the drying mechanism. This prevents over-drying and excessive brittleness of some waste plastics due to temperature differences, reducing the likelihood of powdering during subsequent processing and minimizing raw material loss. By incorporating a pollution prevention device, and through the coordinated operation of a transmission rod, gears, racks, sliding frames, friction columns, elastic telescopic plates, L-shaped frames, and drying mechanism, the friction columns' revolution and reciprocating horizontal sliding ensure that activated carbon gas is evenly distributed throughout the drying mechanism. This activated carbon gas purifies harmful gases emitted from waste plastics during the drying process, preventing direct emissions that could harm workers' health and pollute the external environment. The vertically and horizontally moving drying mechanism ensures the overall dryness of the drying chamber, and the residual heat from the heating mechanism prevents the desiccant particles from being eroded by moisture and oxidized, effectively avoiding increased energy consumption due to residual moisture and extending the desiccant particle replacement cycle.

[0018] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0019] like Figures 1-9 As shown, one embodiment of the present invention is: a washing and crushing device for recycling waste plastics, comprising: a device body 1, a water spraying mechanism 2 provided on the top left side of the device body 1, a collection box 3 provided on the inside left side of the device body 1, a drying mechanism 5 provided on the right side of the device body 1, an electric rotating rod 6 rotatably installed inside the device body 1, a plurality of telescopic mesh plates 7 equidistantly and fixedly installed on the outer wall of the electric rotating rod 6, an inclined plate 8 fixedly installed at the bottom of the square groove of the collection box 3, a crushing mechanism 9 fixedly installed at the bottom of the inner wall of the device body 1, a vertical pipe 10 connected to and fixedly installed at the top of the crushing mechanism 9, a negative pressure mechanism 11 provided at the top of the device body 1, a negative pressure mechanism 11 connected to and fixedly installed at the bottom of the vertical pipe 10, a conveying mechanism 12 fixedly installed on the bottom right side of the inner wall of the device body 1, a conveying pipe 13 provided inside the conveying mechanism 12, an anti-brittleness device 19 provided above the conveying pipe 13 to ensure uniform drying of the plastic, and an anti-pollution device 20 for purifying the plastic during drying provided around the anti-brittleness device 19.

[0020] A reciprocating screw 14 is rotatably installed inside one end of the back of the main body 1. An elliptical block 15 is fixedly installed through the outer wall of one end of the front of the reciprocating screw 14. A scraper ring 16 is slidably installed on the inner wall of the vertical pipe 10 via a spring. A horizontal bar 17 is fixedly installed inside the bottom end of the scraper ring 16. A round wheel 18 is rotatably installed through the outer wall of the horizontal bar 17. The output end of the water spraying mechanism 2 is located inside the main body 1. A square groove is opened on the right side of the collection box 3. A drain pipe 4 is fixedly installed through the left end of the collection box 3. The drain pipe 4 is connected to an external water pump. The telescopic end of the telescopic mesh plate 7 contacts the inner side wall of the collection box 3. The bottom of the inclined plate 8 is located inside the left end of the crushing mechanism 9. The left end of the conveying pipe 13 is connected to and fixedly installed on the right side of the crushing mechanism 9.

[0021] One end of the reciprocating screw 14 is connected to the electric rotating rod 6 via a conveyor belt, and the other end of the reciprocating screw 14 moves through the interior of the vertical tube 10. The outer wall of the reciprocating screw 14 is a non-self-locking reciprocating spiral groove, and the circumferential surface of the wheel 18 contacts the outer wall of the elliptical block 15.

[0022] Through the coordinated operation of these various mechanisms, waste plastics can complete an automated process of cleaning, crushing, and drying, saving manpower and improving processing efficiency. Simultaneously, the revolving telescopic mesh plate 7 ensures comprehensive cleaning of the waste plastics before crushing, unlike the single-sided water rinsing of traditional horizontal conveyors. This significantly optimizes the cleanliness of the waste plastics during processing, avoiding the need for secondary cleaning due to inadequate initial cleaning. The elliptical block 15 revolves, continuously changing the internal flow diameter of the vertical tube 10. As the flow diameter decreases, the internal pressure of the vertical tube 10 increases, coordinating with the scraping action of the scraper ring 16 to prevent damp plastic powder from adhering to the inner wall surface of the vertical tube 10. This optimizes the flow of gas and powder within the vertical tube 10, preventing reduced conveying efficiency due to powder adhesion.

[0023] During use, before the waste plastic enters the collection box 3 through the inclined surface on the left end, the electric rotating rod 6 is activated. As the electric rotating rod 6 rotates, it drives the telescopic mesh plate 7 to revolve. The telescopic end of the mesh plate 7 is in close contact with the inner wall of the collection box 3 and receives the waste plastic. Simultaneously, the output end of the water spraying mechanism 2 sprays water to clean the waste plastic. During the revolving process of the telescopic mesh plate 7, dirt and dirty water seep through its surface mesh into the collection box 3. The collection box 3 then extracts the dirty water through the drain pipe 4 and an external water pump. After treatment, the dirty water is fed into the water spraying mechanism 2, achieving water recycling. Simultaneously, after the telescopic mesh plate 7 revolves, the washed wastewater is guided into the crushing mechanism 9 through the inclined plate 8. The crushing mechanism 9 crushes the waste plastic. During this process, the negative pressure mechanism 11 is activated. The negative pressure mechanism 11 extracts the crushed waste plastic powder from the crushing mechanism 9 through the vertical pipe 10. Afterwards, the conveying mechanism 12 is activated. The conveying mechanism 12 feeds the crushed waste plastic into the drying mechanism 5 through the conveying pipe 13 for drying. The drying mechanism 5 then uses external equipment to remove the dried waste plastic from its interior. When the electric rotary rod 6 rotates, it drives the reciprocating screw 14 to rotate via the conveyor belt. As the reciprocating screw 14 drives the elliptical block 15 to revolve inside the vertical tube 10, the elliptical block 15 expands the flow diameter inside the vertical tube 10. At the same time, the elliptical block 15 contacts the outer wall of the rotating wheel 18. The contact of the elliptical block 15 causes the wheel 18 to generate an upward force. The wheel 18 causes the crossbar 17 and the scraper ring 16 to move synchronously. At this time, the scraper ring 16 scrapes the inner wall of the vertical tube 10. When the elliptical block 15 returns to its original position, the flow diameter inside the vertical tube 10 shrinks again. This process repeats until the elliptical block 15 returns to its original position, releasing its contact with the wheel 18. At this time, the scraper ring 16 returns to its original position due to the spring force.

[0024] According to the above embodiments, through the cooperation of the various mechanisms, waste plastics can complete the automated cleaning, crushing, and drying process, saving manpower and improving processing efficiency. At the same time, relying on the revolving telescopic mesh plate 7, the waste plastics are thoroughly cleaned before crushing, which is different from the single-sided water rinsing of traditional horizontal conveying. This greatly optimizes the cleanliness of the waste plastics during processing and avoids the need for secondary cleaning due to poor cleaning. By revolving the elliptical block 15, the internal flow orifice diameter of the vertical tube 10 is continuously changed. When the flow orifice diameter changes from small to large, the internal pressure of the vertical tube 10 is increased. This, in conjunction with the scraping action of the scraper ring 16, prevents wet plastic powder from adhering to the inner wall surface of the vertical tube 10. This optimizes the flow effect of gas and powder inside the vertical tube 10 and prevents the conveying efficiency from being reduced due to powder adhesion inside the vertical tube 10.

[0025] like Figures 1-9 As shown, based on the above embodiments, another embodiment of the present invention further includes an anti-embrittlement device 19; The anti-brittleness device 19 includes a shaped plate 191, which is movably installed on the outer wall of the reciprocating screw 14 with its bottom end penetrating through it. A circular groove plate 192 is provided above the top of the shaped plate 191, and the interior of the circular groove plate 192 is located on the top movement trajectory of the shaped plate 191. An L-shaped hammer plate 193 is fixedly installed on the right side wall of the circular groove plate 192.

[0026] The top of the irregular plate 191 is slidably installed inside the top of the device body 1, and the top of the irregular plate 191 is an arc surface design. The bottom outer wall of the L-shaped hammer plate 193 is slidably installed inside the device body 1 through a spring. The bottom of the L-shaped hammer plate 193 is in contact with the top inclined surface of the conveying pipe 13.

[0027] A drive plate 194 is fixedly installed on the right side wall of the L-shaped hammer plate 193. A transmission rod 195 is rotatably installed through the bottom of the inner wall of the drying mechanism 5. Both ends of the transmission rod 195 are provided with non-self-locking spiral grooves. The spiral groove at the top of the transmission rod 195 is movably installed inside the drive plate 194. The spiral groove at the bottom of the transmission rod 195 is movably installed through the heating mechanism 196. The outer wall of the heating mechanism 196 is slidably installed inside the drying mechanism 5. Several heat-conducting rods 197 are equidistantly and fixedly installed at the inner edge of the drying mechanism 5. The outer wall of the heat-conducting rods 197 movably penetrates the interior of the heating mechanism 196. The heat-conducting rods 197 are connected to the heating mechanism 196 and disperse and guide the heat of the heating mechanism 196.

[0028] The contact of the irregular plate 191 causes the L-shaped hammer plate 193 to reciprocate vertically striking the top of the conveying pipe 13. The vibration of the conveying pipe 13 causes the waste plastics conveyed inside to enter the drying mechanism 5 in an independent and loose state, avoiding the waste plastics from sticking together due to moisture and thus reducing drying efficiency. The reciprocating vertical movement of the heating mechanism 196 makes the heat transfer to the heat-conducting rod 197 more uniform. The heat-conducting rod 197 conducts heat at multiple points, making the heat distribution inside the drying mechanism 5 more balanced. This avoids over-drying of some waste plastics due to temperature differences, which would cause them to become too brittle. It also prevents the waste plastics from becoming powdery in subsequent processing and avoids raw material loss.

[0029] In use, when the reciprocating screw 14 rotates, it is driven by the non-self-locking reciprocating spiral groove on its outer wall, causing the irregularly shaped plate 191 to slide horizontally back and forth along the inside of the top of the main body 1. When the irregularly shaped plate 191 slides horizontally, its arc surface contacts and abuts the arc surface of the circular groove plate 192, thereby generating an upward resisting force. At this time, the circular groove plate 192 drives the L-shaped hammer plate 193 to move upward. When the irregularly shaped plate 191 passes over the single arc surface of the circular groove plate 192, the L-shaped hammer plate 193, through the spring force, suddenly falls from the upward water-filled state and strikes the top of the conveying pipe 13, generating vibration. This process is repeated, and under the striking of the L-shaped hammer plate 193, the conveying pipe 1... 3. During vibration, waste plastic is conveyed; when the L-shaped hammer plate 193 drives the drive plate 194 to move upward, the drive plate 194 slides along the outer wall of the spiral groove of the transmission rod 195. Relying on the limit of the non-self-locking spiral groove, the transmission rod 195 generates a rotational force. When the transmission rod 195 rotates, it drives the heating mechanism 196 to slide upward along the inner wall of the drying mechanism 5 through the non-self-locking spiral groove at its bottom. Then the drive plate 194 resets, and the transmission rod 195 reverses to reset the heating mechanism 196. When the heating mechanism 196 slides along the outer wall of the heat-conducting rod 197, it relies on the heat-conducting rod 197 to conduct heat at various points.

[0030] According to the above embodiment, the L-shaped hammer plate 193 is able to reciprocate vertically to strike the top of the conveying pipe 13 by the contact of the irregular plate 191. The conveying pipe 13 relies on vibration to keep the waste plastic conveyed inside it in an independent and loose state before entering the drying mechanism 5, so as to avoid the waste plastic sticking together due to moisture and thus reducing the drying efficiency. The reciprocating vertical movement of the heating mechanism 196 makes the heat transfer to the heat conduction rod 197 more uniform. The heat conduction rod 197 conducts heat at multiple points, so that the heat distribution inside the drying mechanism 5 is more balanced. This avoids the waste plastic from being over-dried due to temperature difference and becoming too brittle, and prevents the waste plastic from becoming powdery in subsequent processing, thus avoiding raw material loss.

[0031] like Figures 1-9As shown, based on the above embodiments, another embodiment of the present invention further includes an anti-pollution device 20; The anti-pollution device 20 includes a gear 201, which is internally penetrated and fixedly installed on the outer wall of the transmission rod 195. Two racks 202 are symmetrically and slidably installed on the top of the inner wall of the drying mechanism 5. A sliding frame 203 is fixedly installed on the outer side wall of the racks 202. A friction column 204 is rotatably installed inside the sliding frame 203.

[0032] The rack 202 meshes with the gear 201, and the outer wall of the friction column 204 contacts the top of the inner wall of the drying mechanism 5. The friction column 204 is circular and contains activated carbon particles.

[0033] A flexible telescopic plate 205 is fixedly installed at the bottom of the rack 202. An L-shaped frame 206 is fixedly installed at the bottom of the telescopic end of the flexible telescopic plate 205. The bottom of the L-shaped frame 206 is slidably installed on the top of the heating mechanism 196. A drying mechanism 207 is fixedly installed inside the L-shaped frame 206. The drying mechanism 207 contains desiccant particles.

[0034] The revolution and reciprocating horizontal sliding of the friction column 204 ensures that the activated carbon gas is evenly distributed inside the drying unit 5. The activated carbon gas purifies the harmful gases volatilized from the waste plastics during the drying process, preventing direct emissions that could harm the health of workers and pollute the external environment. The vertically and horizontally moving drying unit 207 ensures that the drying gas maintains the overall dryness inside the drying unit 5. The residual heat from the heating unit 196 prevents the desiccant particles from being eroded by moisture and thus oxidized, effectively avoiding increased energy consumption due to residual moisture and extending the replacement cycle of the desiccant particles.

[0035] In use, the transmission rod 195 drives the gear 201 to rotate. When the gear 201 rotates, it drives the meshing rack 202 to slide horizontally along the top of the inner wall of the drying mechanism 5. The symmetrically arranged racks 202 slide horizontally in opposite directions. The racks 202 drive the sliding frame 203 to move synchronously. When the sliding frame 203 moves horizontally back and forth, it drives the friction column 204 to move synchronously along the top of the inner wall of the drying mechanism 5. At this time, the friction column 204 generates friction and rotates inside the sliding frame 203. When the friction column 204 rotates, it causes the activated carbon gas generated by the activated carbon particles inside it to evaporate and diffuse evenly. When the rack 202 moves horizontally, it drives the elastic telescopic plate 205 to move synchronously. The telescopic end of the elastic telescopic plate 205 pulls the L-shaped frame 206 to move synchronously along the top of the heating mechanism 196. The L-shaped frame 206 drives the drying mechanism 207 to move synchronously. At the same time, the rising heating mechanism 196 raises the height of the drying mechanism 207. Thus, the drying mechanism 207 can evaporate dry gas during the horizontal and vertical movement.

[0036] According to the above embodiment, the revolution and reciprocating horizontal sliding of the friction column 204 promotes the uniform filling of the interior of the drying mechanism 5 with activated carbon gas. The activated carbon gas purifies the harmful gases volatilized from the waste plastic during the drying process, avoiding direct emissions that could harm the health of workers and pollute the external environment. The vertical and horizontal movement of the drying mechanism 207 ensures the overall dryness of the interior of the drying mechanism 5, and the residual heat of the heating mechanism 196 prevents the desiccant particles from being eroded by moisture and thus oxidized, effectively avoiding increased energy consumption due to residual moisture, and extending the replacement cycle of the desiccant particles.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
