Description

Technical Field

[0001] This invention relates to the field of Pams resin recycling, specifically to a waste recycling device and method for Pams resin production. Background Technology

[0002] PAMS resin is short for polyalpha-methylstyrene resin. It is a low molecular weight thermoplastic specialty resin obtained by homopolymerization of alpha-methylstyrene monomer. It is often called pure monomer resin or AMS resin. It is a commonly used thickener and modifier in industry. PAMS resin production takes cationic solution polymerization as the core technology route. The mainstream production methods are batch reactor polymerization and continuous pipeline or tower polymerization. The core process consists of seven units: raw material preparation, polymerization reaction, quenching and neutralization, solvent recovery, product separation, post-processing, and environmental protection treatment. The entire process is carried out in a closed inert atmosphere to ensure product quality and safety.

[0003] When Pams resin undergoes changes in grade, start-up / shutdown, or process fluctuations during production, it can produce solid, substandard resin lumps that are darker in color and have the wrong softening point. During production, the resin easily adheres to the inner wall of the polymerization reactor, the agitator, and the heat exchange coils. During the reaction, some of the resin remains stuck to the reactor wall, accumulating and gradually solidifying into solid sheets or lumps. When cleaning the reactor, scraping these lumps creates irregular, large pieces of resin waste. This resin waste is typically crushed and recycled (see attached document for details). Figure 11 Workers directly feed large pieces of resin into the crushing mechanism. Because the resin volume exceeds the clamping range of the cutter rollers, the blades cannot grip or pull it into the crushing zone, leaving it stuck between the feed inlet and the cutter rollers, making crushing difficult. Furthermore, PAMS is a low-molecular-weight thermoplastic resin, highly sensitive to heat. The crushing process itself generates continuous heat, requiring repeated shearing and friction within the crushing chamber to break it. This significantly prolongs the residence time, and the frictional heat causes the chamber temperature to rise far above the PAMS resin's softening point. At this point, the PAMS resin immediately softens and becomes sticky, adhering to the crushing mechanism. Prolonged exposure can lead to blockages, affecting the overall crushing effect. Moreover, PAMS is a hard and brittle material at room temperature, easily crumbling into powder upon impact. When the crusher blades impact at high speed, the resin does not stretch or deform like plastic; instead, it fractures brittlely, instantly disintegrating into a large amount of fine dust instead of larger fragments. This causes dust to gush out from the feed inlet, affecting the overall processing environment and hindering prolonged crushing and recycling operations.

[0004] In summary, the above-mentioned structure requires repeated shearing of larger pieces of material within the crushing chamber during actual use, causing them to adhere to the crushing mechanism for extended periods, which affects the overall crushing effect. Furthermore, the crushing process generates a large amount of fine dust, impacting the overall processing environment and making it difficult for workers to perform crushing and recycling operations for extended periods. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a waste recycling device and recycling method for Pams resin production, in order to solve the technical problem.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a waste recycling device for Pams resin production, comprising a housing, an inlet on the housing, and a crushing component rotatably disposed inside the housing. Inclined platforms are symmetrically disposed above the crushing component inside the housing, and the gap between the inclined platforms is used for dropping small pieces of resin. An extrusion plate that cooperates with the inclined platforms is slidably disposed at the top inside the housing. The inclined platform is elastically provided with a guide post that cooperates with the extrusion plate. The guide post can slide vertically through the extrusion plate. A toothed block is provided on one side of the guide post, and a fixed gear that cooperates with the toothed block is rotatably provided inside the inclined platform. At the same time, a threaded rod that cooperates with the fixed gear is rotatably provided inside the housing at the feed inlet. The threaded rod is used to drive the sealing plate at the feed inlet to slide vertically.

[0007] By adopting the above technical solution, the resin to be crushed is reciprocated and extruded by the extrusion plate, which compresses it into small pieces. These pieces fall through the gap of the inclined platform to the crushing component at the bottom. This process effectively prevents the resin from getting stuck between the crushing rollers. Furthermore, the small pieces of resin reduce the number of shearing operations at the crushing component during the crushing process. The threaded rod at the feed inlet rotates, causing the sealing plate to slide downwards through the threaded rod. At this time, the sealing plate seals the housing at the feed inlet. During the crushing process of the internal crushing mechanism, a large amount of fine dust is isolated inside the housing by the sealing plate, effectively preventing fine dust from gushing out of the feed inlet.

[0008] The present invention is further configured such that a baffle is slidably provided at the bottom of the inclined platform, wherein the top end of the baffle is connected to the bottom of the guide post, and an elastic component is connected between the guide post and the inclined platform.

[0009] Preferably, during the downward sliding of the extrusion plate, the guide post will drive the baffle to slide down to both sides of the crushing component. The baffle restricts the resin to the effective crushing zone in the middle of the crushing component, so that it can only be continuously sheared by the crushing component, which improves the overall crushing efficiency. In addition, the extrusion plate slides back and forth during the extrusion process. Under the action of the elastic component, the baffle is also in a vertical vibration state at the bottom. When some softened resin is thrown onto the baffle, it will be quickly shaken off, which effectively prevents the resin from accumulating thickly on the inner wall of the shell and forming a hard shell.

[0010] The present invention is further configured such that the toothed blocks on the guide post are partially provided, and a damping structure is provided at one end of the fixed gear.

[0011] Preferably, the toothed blocks are partially set so that when the cylinder drives the extrusion plate to slide downward, the toothed blocks will first mesh with the fixed gear. When the extrusion plate moves downward, the toothed blocks will gradually disengage from the fixed gear. At this time, the sealing plate completes the sealing of the feed inlet. Subsequently, during the reciprocating sliding extrusion process driven by the cylinder, the toothed blocks will not contact the fixed gear, thereby further ensuring the sealing effect of the sealing plate at the feed inlet.

[0012] The present invention is further configured such that a stepper motor is provided on one side of the housing, wherein the output end of the stepper motor extends through the housing and is connected to the crushing component.

[0013] Preferably, the stepper motor allows operators to easily control the rotation speed of the crushing components within the housing, thereby adjusting the overall crushing efficiency and improving the overall practicality of the device.

[0014] The present invention is further configured such that the crushing component includes an active crushing wheel, a driven crushing wheel, an active gear and a driven gear, the output end of the stepper motor is connected to the active crushing wheel, one end of the active crushing wheel is connected to the active gear, a driven gear meshes with one side of the active gear, and one end of the driven gear is connected to the driven crushing wheel.

[0015] Preferably, when the stepper motor drives the active crushing wheel to rotate, its active gear will also rotate. Through the meshing of the active gear and the driven gear, the driven crushing wheel is driven to rotate. Furthermore, under the action of the active gear and the driven gear, the active crushing wheel and the driven crushing wheel can rotate and mesh together inward, thereby improving the overall crushing effect.

[0016] The invention is further configured such that a slot is provided at the bottom of the inclined platform at the baffle, wherein the inner wall of the slot is vertically arranged.

[0017] Preferably, after subsequent crushing is completed, when the cylinder drives the extrusion plate to slide upward to reset, its elastic component will drive the guide post to reset. During this process, the baffle itself will contact the inner wall of the slot. The slot facilitates the scraping off of the resin adhering to the baffle, effectively preventing the resin from accumulating on one side of the baffle.

[0018] The present invention is further configured such that a cylinder is provided at the top of the housing, and the output end of the cylinder extends through the housing and is connected to a pressing plate.

[0019] Preferably, the cylinder facilitates the downward sliding of the extrusion plate, which, in conjunction with the inclined platform inside the housing, completes the extrusion and crushing of the resin.

[0020] The present invention is further configured such that a bag filter assembly is provided on one side of the housing located at the feed inlet.

[0021] Preferably, during the crushing process, the bag filter assembly is activated, drawing dust into the lower housing of the bag filter from the air inlet under negative pressure, preventing dust leakage and effectively preventing internal dust explosions.

[0022] The present invention is further configured such that a worm is provided on one side of the fixed gear, and a worm wheel is rotatably provided on one side of the worm, wherein the worm wheel is sleeved on the outer wall of the threaded rod.

[0023] Preferably, the fixed gear rotates under the action of the toothed block, and the worm at one end of it will rotate accordingly. Through cooperation with the worm wheel, the threaded rod at the feed inlet will rotate.

[0024] A method for recycling waste from the production of Pams resin according to claim 1, comprising the following steps: Step 1: Large pieces of resin are fed into the housing through the feed port. The extrusion plate then slides down and, together with the inclined platform inside the housing, performs initial extrusion and crushing of the large pieces of resin. Small pieces of resin then fall to the bottom through the gaps in the inclined platform. Step 2: As the extrusion plate slides downward, the guide post on its inclined platform will be driven downward by the extrusion plate. Under the action of the fixed gear and the transmission assembly, the sealing plate at the feed inlet slides downward to seal the feed inlet. Then the crushing assembly works to crush the small pieces of resin. Step 3: After the resin is broken down, it will fall into the collection box at the bottom. The staff will then use the handle on one side of the collection box to remove and process the collected resin.

[0025] By adopting the above technical solution, the resin to be crushed is reciprocated and extruded by the extrusion plate to compress it into small pieces. During the crushing process, the number of shearing operations at the crushing component is reduced. The sealing plate slides downward through the threaded rod. At this time, the sealing plate is located at the feed inlet and seals its shell, effectively preventing fine dust from gushing out of the feed inlet.

[0026] In summary, the present invention has the following main beneficial effects: This invention features a crushing assembly within a housing, with symmetrically mounted inclined platforms at the top. When resin is fed into the housing, it falls to the top of the inclined platforms. At this point, a cylinder is activated, causing a pressing plate to slide downwards. The pressing plate reciprocates and compresses the resin to be crushed, breaking it into small pieces that fall through the gaps in the inclined platforms to the crushing assembly at the bottom. This process effectively prevents resin from getting stuck between the crushing rollers. Furthermore, the smaller resin pieces reduce the number of shearing operations at the crushing assembly, thus preventing the resin from softening and becoming sticky due to high temperatures. This invention features a guide post that is elastically installed vertically on an inclined platform. As the extrusion plate moves downward, the guide post slides downward along with the extrusion plate. At this time, the toothed block on the guide post drives the fixed gear on one side to rotate. Through the cooperation of the worm and worm wheel, the threaded rod at the feed inlet rotates, thereby causing the sealing plate to slide downward through the threaded rod. At this time, the sealing plate is located at the feed inlet and seals its shell. During the crushing process of the internal crushing mechanism, a large amount of fine dust is isolated inside the shell by the sealing plate, effectively preventing fine dust from gushing out from the feed inlet and improving the overall recycling environment for workers. This invention features a baffle at the bottom of the inclined platform, connected to guide posts. As the extrusion plate slides downwards, the guide posts cause the baffle to slide down to both sides of the crushing component. The baffle confines the resin within the effective crushing zone of the crushing component, ensuring it is continuously sheared by the component, thus improving overall crushing efficiency. Furthermore, the extrusion plate slides back and forth during the extrusion process, causing the baffle to vibrate vertically at the bottom. When some softened resin is thrown onto the baffle, it is quickly shaken off, effectively preventing resin from accumulating on the inner wall of the shell and forming a hard shell.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of the present invention will now be described.

[0031] Example 1: Please refer to Figures 1-10 The device and method for recycling waste from the production of Pams resin shown herein include a shell 1, a feed inlet 4, a bag filter assembly 3, an extrusion mechanism, a crushing assembly 10, and a transmission mechanism. During the reaction, some resin adheres to the reactor wall and accumulates, eventually solidifying into a hard sheet or block. When cleaning the reactor, scraping it off will form irregular large pieces of resin waste. These large pieces of resin waste are discharged into the shell 1 through the feed inlet 4. An inclined platform 8 is symmetrically arranged above the crushing assembly 10 inside the shell 1. A guide post 16 that cooperates with the extrusion plate 7 is elastically arranged on the inclined platform 8. The guide post 16 can slide vertically through the extrusion plate 7. At the same time, a toothed block 18 is arranged on one side of the guide post 16, and a fixed gear 20 that cooperates with the toothed block 18 is rotatably arranged inside the inclined platform 8. During the downward sliding of the extrusion plate 7, the guide post 16 will move downward, and at this time the toothed block 18 will drive the fixed gear 20 to rotate. A worm 19 is provided on one side of the fixed gear 20, and a worm wheel 14 is rotatably provided on one side of the worm 19. The worm wheel 14 is sleeved on the outer wall of the threaded rod 12. When the fixed gear 20 rotates under the action of the tooth block 18, the worm 19 at one end will rotate accordingly. Through the cooperation with the worm wheel 14, the threaded rod 12 at the feed inlet 4 rotates. The threaded rod 12 is located at the slide groove 13, and the side wall of its sealing plate 15 can slide at the slide groove 13. The threaded rod 12 is used to drive the sealing plate 15 at the feed inlet 4 to slide vertically. The slide groove 13 ensures the stability of the sealing plate 15. During the sliding process, the sealing plate 15 will move downward to seal the feed inlet 4. During the crushing process, a large amount of fine dust will be isolated inside the housing 1 by the sealing plate 15, effectively preventing fine dust from gushing out from the feed inlet 4 and improving the overall recycling environment for the staff. Furthermore, a bag filter assembly 3 is installed on the side of the housing 1 near the feed inlet 4. During the crushing process, the bag filter assembly 3 is activated and draws dust into the lower chamber of the bag filter from the air inlet under negative pressure, preventing dust leakage and effectively preventing dust explosion inside. Furthermore, the gap between the inclined platforms 8 is used to drop small pieces of resin. At this time, the large pieces of resin will stay at the top of the inclined platform 8. Then, the cylinder 2 at the top of the housing 1 is activated. Under the action of the cylinder 2, the extrusion plate 7 at the top of the housing 1 will slide downward. With the cooperation of the extrusion plate 7 and the inclined platform 8, the large pieces of resin waste are crushed and squeezed into small pieces. The small pieces of resin fall through the gap between the inclined platforms 8 to the bottom crushing component 10. This process effectively prevents the resin from getting stuck between the crushing rollers. Then, the bottom crushing component 10 crushes the resin. During the crushing process, the number of shearing operations at the crushing component 10 is reduced, thereby preventing the resin from softening and becoming sticky due to high temperature. At the same time, a collection box 11 is set at the bottom of the housing 1. The crushed resin will fall into the bottom collection box 11. Since a handle 5 is set on one side of the collection box 11, it is convenient for the staff to take the collection box out of the housing 1.

[0032] For details regarding the above embodiments, please refer to [link / reference]. Figure 10The toothed block 18 on the guide post 16 is partially set, and one end of the fixed gear 20 is provided with a damping structure. The partially set toothed block 18 makes it easy for the cylinder 2 to drive the extrusion plate 7 to slide downward. The toothed block 18 will first mesh with the fixed gear 20. When the extrusion plate 7 moves downward, the toothed block 18 will gradually disengage from the fixed gear 20. At this time, the sealing plate 15 completes the sealing of the feed port 4. Subsequently, during the process of the cylinder 2 driving the extrusion plate 7 to reciprocate and slide, the toothed block 18 will not contact the fixed gear 20. This can further ensure the sealing effect of the sealing plate 15 at the feed port 4.

[0033] For details regarding the above embodiments, please refer to [link / reference]. Figure 7 The crushing component 10 includes an active crushing wheel 1001, a driven crushing wheel 1002, an active gear 1003, and a driven gear 1004. The active crushing wheel 1001 is connected to the output end of the stepper motor 6, and the active gear 1003 is connected to one end of the active crushing wheel 1001. The driven gear 1004 meshes with one side of the active gear 1003, and the driven crushing wheel 1002 is connected to one end of the driven gear 1004. When the stepper motor 6 drives the active crushing wheel 1001 to rotate, the active gear 1003 will rotate accordingly. Through the meshing of the active gear 1003 and the driven gear 1004, the driven crushing wheel 1002 is driven to rotate. Under the action of the active gear 1003 and the driven gear 1004, the active crushing wheel 1001 and the driven crushing wheel 1002 can rotate and mesh together inward, improving the overall crushing effect.

[0034] Example 2: Please refer to Figure 5 and Figure 6 The waste recycling equipment and method for Pams resin production shown herein have an overall structure similar to that of Embodiment 1. A baffle 9 is slidably disposed at the bottom of the inclined platform 8, with the top of the baffle 9 connected to the bottom of the guide post 16. An elastic component is connected between the guide post 16 and the inclined platform 8. As the extrusion plate 7 slides downward, the guide post 16 drives the baffle 9 to slide down to both sides of the crushing component 10. The baffle 9 restricts the resin to the effective crushing zone in the middle of the crushing component 10, allowing it to be continuously sheared by the crushing component, thus improving the overall crushing efficiency. Furthermore, the extrusion plate 7 slides back and forth during the extrusion process. Under the action of the elastic component, the baffle 9 is also in a vertical vibration state at the bottom. When some softened resin is thrown onto the baffle 9, it is quickly shaken off, effectively preventing the resin from accumulating and forming a hard shell on the inner wall of the shell 1.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 6A slot 17 is provided at the bottom of the inclined platform 8, located at the baffle 9. The inner wall of the slot 17 is vertical. After subsequent crushing, when the cylinder 2 drives the extrusion plate 7 to slide upwards for reset, its elastic component will drive the guide post 16 to reset. During this process, the baffle 9 itself will contact the inner wall of the slot 17. The slot 17 facilitates the scraping of the resin adhering to the baffle 9, effectively preventing the resin from accumulating on one side of the baffle 9.

[0036] In practical operation, the present invention is used by feeding large pieces of PAMS resin to be crushed and recycled into the housing 1 through the feed port 4. Since there are inclined platforms 8 located at the top of the crushing component 10 inside the housing 1, the symmetrically arranged inclined platforms 8 can easily obstruct the large pieces of resin. By activating the cylinder 2 at the top of the housing 1, the extrusion plate 7 inside the housing 1 is driven to slide downward under the action of the cylinder 2. With the cooperation of the extrusion plate 7 and the inclined platforms 8, the large pieces of resin waste are crushed and squeezed into small pieces. The small pieces of resin fall into the bottom crushing component 10 through the gap between the inclined platforms 8. In this process, the resin is effectively prevented from getting stuck between the crushing rollers. In addition, the small pieces of resin can reduce the number of shearing times at the crushing component during the crushing process, thereby preventing the resin from softening and becoming sticky due to high temperature. Furthermore, a guide post 16 is elastically set on the inclined platform 8. As the extrusion plate 7 slides downward, the guide post 16 will move downward as well. At this time, the toothed block 18 on one side of the guide post 16 will drive the fixed gear 20 in the inclined platform to rotate. Through the cooperation of the fixed gear 20 and the worm gear 19 and worm wheel 14, the threaded rod 12 will rotate. During this process, the threaded rod 12 will drive the sealing plate 15 at the feed inlet 4 to slide downward until the bottom of the sealing plate 15 blocks the feed inlet 4. Then, the crushing component 10 will be driven by the stepper motor 6 to perform vertical crushing. During this process, a large amount of fine dust will be isolated in the housing 1 by the sealing plate 15, effectively preventing fine dust from gushing out of the feed inlet 4. After that, the crushed resin will fall into the collection box 11 at the bottom, thereby improving the overall recycling environment for the staff.
