Double-layer limiting type plastic pin cleaning wastewater treatment tooling

Abstract

This invention relates to the field of wastewater treatment technology, and in particular to a double-layer limiting plastic pin cleaning wastewater treatment tool, including a wastewater cylinder and a starting component for treating double-layer limiting plastic pin cleaning wastewater on a support block. Through the arrangement of the starting component, filtration component, and concentrating component, the bearing bar and bearing rod drive the scraper at the bottom of the lifting column to reciprocate and scrape along the curved surface of the irregular platform. The bearing plate continuously impacts and touches the inner wall of the cylinder, generating high-frequency vibration. The scraping and vibration work together to clean the plastic impurities adhering to the surface and pores of the irregular platform mesh in real time. Addressing the electrostatic adsorption effect generated by the friction between the release agent film on the surface of the plastic debris and the water flow, this dual action prevents plastic impurities from embedding and jamming the filter pores, avoiding the core problems of easy filter layer clogging, continuous decline in flow efficiency, and excessive fluctuations in suspended solids in the effluent. It maintains a stable effective flow area on the irregular platform filter surface and reduces the frequency of filter layer disassembly and replacement.

Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a double-layer limiting plastic pin cleaning wastewater treatment tool. Background Technology

[0002] The double-layer limiting plastic pin cleaning wastewater treatment fixture is a specialized environmental protection device designed to address water and solid waste pollution from the batch cleaning of precision plastic pins. The cleaning wastewater treated by this fixture originates from the process of rinsing and soaking the plastic pins in the cleaning solution, which carries away residual impurities from the parts' surfaces. Plastic pins are mostly injection molded from engineering plastics such as POM, PA66, and PET, and subsequently undergo machining processes such as gate trimming, flash trimming, and end face precision cutting. High-speed cutting of the plastic substrate by the cutting tools generates plastic debris. Currently, in the double-layer limiting plastic pin cleaning wastewater treatment process, the high-pressure spray cleaning action removes plastic debris from the pin surface. All the aforementioned debris is detached and enters the cleaning solution. At the same time, the release agent, oil, and cleaning agent in the wastewater mix with the plastic debris, changing the surface properties of the debris. The wastewater from cleaning plastic pins also contains emulsified release agent, trace amounts of mineral oil, and water-based surfactants. These organic components form an adhesive liquid film on the surface of the plastic debris, which is equivalent to coating the particles with a "binder". Plastic itself is an insulating material. When the plastic debris collides with each other and rubs against the wall in the turbulent water flow, it will become statically charged. The stainless steel / plastic cylinder wall and the surface of the filter media fiber will also generate surface charges due to water flow friction. Opposite charges attract each other, causing the plastic debris to actively adhere to the filter layer surface, thereby clogging the filter layer. The clogging of the filter layer will directly destroy the filtration effect and lead to the loss of control over the effluent quality. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a double-layer limiting plastic pin cleaning wastewater treatment tool.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a double-layer limiting plastic pin cleaning wastewater treatment fixture, including a wastewater cylinder, with irregularly shaped end caps fixedly connected to the top and bottom of the wastewater cylinder, four support legs fixedly connected to the outside of the wastewater cylinder, a support block provided inside the wastewater cylinder, and a starting component for treating double-layer limiting plastic pin cleaning wastewater provided on the support block. The starting component includes a moving block and a touch plate, which, through the cooperation of the moving block and the touch plate, can provide power for treating plastic impurities in the double-layer limiting plastic pin cleaning wastewater. The starting component includes two support platforms, which are fixedly connected to both ends of the support block, and both support platforms are fixedly connected to the inner wall of the wastewater cylinder. The irregularly shaped end cap at the top of the wastewater cylinder is provided with... The reducing flange pipe has a discharge pipe at the bottom of the wastewater tank with an irregularly shaped end cap. An inspection hole is located on the outside of the wastewater tank. A support block is fixedly connected to the bottom of each support platform, and a support column is fixedly connected to each support block. A first and second turntable are movably connected to the outside of each support column, and a touch plate is fixedly connected to the outside of each first and second turntable. A connecting frame is fixedly connected to the bottom of each moving block, and a cylinder is located on each connecting frame. A second push bar and a first push bar are movably connected to the cylindrical part of each connecting frame, and the end of each first and second push bar furthest from the connecting frame is movably connected to the corresponding touch plate. The starting assembly contains a placement shell, which is fixedly connected to the center of the support block. Each housing has a fixed top casing, inside which is a motor. Bearings are mounted on the housing, and threaded columns are fixedly connected to the inner rings of the bearings. The motor's output shaft is also fixedly connected to the threaded columns. Threaded blocks are threaded to the outer sides of the threaded columns, and connecting strips are fixedly connected to the outer sides of the threaded blocks. A connecting rod is fixedly connected between two moving blocks, and a positioning sleeve is fixedly connected to the outer side of the connecting rod. The bottom of the connecting strip is fixedly connected to the positioning sleeve. A filter table is fixedly connected inside the wastewater tank. The filter table has a collection component for treating plastic impurities in the wastewater from the double-layer limited-position plastic pin cleaning process. The collection component contains a lifting column and a scraper. The lifting column and scraper work together to collect the plastic impurities. The collection component also contains a shaped platform... The shaped platform is fixedly connected to the bottom of the filter table. Each first and second turntable has a support strip fixedly connected to its outer side. A support rod is fixedly connected to the end of each support strip away from the corresponding turntable. Several limiting cylinders are fixedly connected to the bottom of each support rod. A lifting column is inserted into each limiting cylinder. Each limiting cylinder has a stop plate inside, and each stop plate is fixedly connected to its corresponding lifting column. Each limiting cylinder also has a spring inside, and both ends of each spring are fixedly connected to the inner wall of the corresponding limiting cylinder and the stop plate, respectively. The end of each lifting column away from the stop plate is fixedly connected to a scraper. The shaped platform has several small mesh holes for filtering plastic impurities, and the platform is semi-circular. Each scraper is flush with the inner wall of the shaped platform.The centralized assembly includes a support plate, with each end of the support plate fixedly connected to two support columns. A support arm is fixedly connected to the outer side of the support plate, and an actuating cylinder is fixedly connected to the top of the support arm. Each actuating cylinder has a telescopic column inserted into it, and a tension spring is sleeved on the outer side of each telescopic column. Inside each actuating cylinder is a support plate, and a support plate is fixedly connected to each telescopic column. Each tension spring has its two ends fixedly connected to the corresponding support plate and the inner wall of the actuating cylinder, respectively. A retractable block is fixedly connected to the end of each telescopic column away from the support plate. A trigger block is fixedly connected to the outer side of the positioning sleeve. When the trigger block moves to the position corresponding to the retractable block, the trigger block and the retractable block engage. The first and second push bars on the outer sides of each connecting frame are intersecting, and the support bars on the outer sides of each first turntable are in the same orientation. The support bars on the outer sides of each second turntable are also in the same orientation, and the support bars on the outer sides of the first and second turntables are intersecting.

[0005] Through the above technical solution, when the double-layer limiting plastic pin cleaning fixture completes the cleaning of the plastic pins, the plastic pin cleaning wastewater is introduced from the plastic pin cleaning fixture into the reducing flange pipe. Then, the ball valve on the reducing flange pipe is opened, and the plastic pin cleaning wastewater flows from the reducing flange pipe into the interior of the wastewater tank. The plastic impurities in the plastic pin cleaning wastewater then adhere to the inner wall of the irregular-shaped platform. The motor is then started, driving the threaded column to rotate. As the threaded column rotates, it drives the threaded block to move towards the bottom of the placement shell. As the threaded block moves, it drives the connecting strip to move. As the connecting strip moves, it pushes the positioning sleeve to move. As the positioning sleeve moves, it drives the connecting rod to move. As the connecting rod moves, it drives two moving blocks to move towards the bottom of the wastewater tank. As the moving blocks move, they drive the corresponding connecting frame to move. As the connecting frame moves, it squeezes the first and second push bars, causing them to expand along the cylindrical part of the connecting frame. Then, the first and second push bars, through the touch plate, drive the first and second turntables to rotate along the support column. The expansion causes the support column and the first turntable to rotate, which in turn drives the corresponding bearing strips to rotate. Since both the bearing strips and the touch plate are V-shaped, each bearing strip rotates and contracts when the touch plate expands. When the bearing strips rotate and contract, they drive the bearing rods to move synchronously. Then, the bearing rods drive the corresponding limiting cylinders to move. When the limiting cylinders move, they drive the lifting column to move. When the lifting column moves, it drives the two scrapers to move along the inner wall of the shaped platform. Since the scrapers are initially located at the top of the inner wall of the shaped platform and the lifting column enters the interior of the limiting cylinder, the spring is in a compressed state. When the scrapers move along the shaped platform, since the shaped platform is semi-arc, the scrapers drive the lifting column to move. Then, the compressed spring causes the spring to rebound. When the spring rebounds, it drives the lifting column to move. When the lifting column moves, it keeps the scrapers in contact with the inner wall of the shaped platform. Then, the motor rotates in both directions to make the threaded column rotate repeatedly. When the scrapers move, they scrape the plastic impurities attached to the shaped platform towards the bottom of the shaped platform.

[0006] As a preferred embodiment of the present invention, the movable block is provided with a filtration component for cooperating with the starting component. The filtration component contains a cleaning frame and a filter plate. The cooperation of the cleaning frame and the filter plate promotes the flow of wastewater from the double-layer limiting plastic pin cleaning process. The filtration component contains two sealing cylinders, each fixedly connected to the bottom of the support block. A movable column is inserted into each sealing cylinder, and a sealing gasket is provided inside each sealing cylinder. Each movable column is fixedly connected to its corresponding sealing gasket, and the end of each movable column away from the sealing gasket is fixedly connected to its corresponding movable block. Each sealing cylinder has two actuation holes. Each of the four movable blocks has a guide tube fixedly connected to its outer side. The filter assembly contains four support frames, and each movable block has two fixed blocks fixedly connected to its outer side. Each fixed block has a support frame fixedly connected to its outer side. A filter plate is located between each pair of support frames on opposite sides, and the filter plate is fixedly connected to the two corresponding support frames. Each support frame has a slot for placing a clip, and a clip is engaged in the slot of each support frame. Two plugs are inserted into each support frame, and each plug passes through the corresponding clip. A cleaning frame is located on the outer side of each of the four clips, and the cleaning frame is fixedly connected to the four clips and fits against the inner wall of the wastewater cylinder.

[0007] Through the above technical solution, when the plastic pin cleaning wastewater is inside the wastewater tank, and the moving block moves, it drives the moving column to move towards the bottom of the sealing cylinder. The moving column, in turn, pushes down the sealing gasket. This downward pressure forces air out of the sealing cylinder through two guide pipes on the outside of the cylinder. The pressure generated by this discharge from the guide pipes accelerates the movement of the plastic pin cleaning wastewater inside the wastewater tank. This movement promotes the falling of plastic impurities from the wastewater into the inner wall of the shaped platform. Simultaneously, the moving block moves the corresponding support frame, which, through the locking strip, moves the cleaning frame. This cleaning frame scrapes away plastic impurities adhering to the inner wall of the wastewater tank, causing them to fall into the inner wall of the shaped platform. When the cleaning frame needs to be replaced, the insertion of the bolt into the support frame and the locking strip into the support frame are released, and the support frame is then removed. The filter plate moves synchronously as the carrier frame descends, intercepting large particles of impurities in the plastic pin cleaning wastewater. The filter plate also pushes the wastewater inside the wastewater cylinder towards the inner wall of the shaped platform, accelerating its separation as it impacts the inner wall. As the positioning sleeve descends, it moves the trigger block towards the position of the retractable block. When the trigger block reaches the corresponding position, the retractable block, squeezed by the trigger block, moves the telescopic column towards the inside of the trigger cylinder. The telescopic column then causes the carrier plate to continuously impact the inner wall of the trigger cylinder, generating vibration and stretching the spring. When the trigger block leaves the corresponding position of the retractable block, the stretched spring resets the carrier plate. The continuous vibration helps to shake off plastic impurities on the shaped platform, preventing the small holes of the platform from being blocked by plastic impurities.

[0008] Compared with the prior art, the beneficial effects that this invention can achieve are: This invention, through the setup of a starting component, a filtration component, and a centralized component, allows the threaded block to rise and fall synchronously via connecting strips, positioning sleeves, and connecting rods. The connecting frame at the bottom of the linkage moving block pushes against the touch plate via first and second push strips, causing the first and second turntables to rotate reciprocally along the support column. This, in turn, drives the scraper at the bottom of the lifting column to reciprocate and scrape along the curved surface of the irregular platform via the bearing strips and bearing rods. Simultaneously, the positioning sleeve, along with the lifting stroke, causes the trigger block to reciprocate and touch the retracting block, pushing the telescopic column and bearing plate to compress the tension spring. This causes the bearing plate to continuously impact the inner wall of the touch cylinder, generating high-frequency vibration. The combined effect of scraping and vibration effectively cleans plastic impurities adhering to the surface and pores of the irregular platform mesh in real time. Addressing the electrostatic adsorption effect generated by the friction between the release agent film on the surface of plastic debris and water flow, this dual action prevents plastic impurities from embedding and jamming the filter pores. This avoids the core problems of easy filter layer clogging, continuous decline in flow efficiency, and excessive fluctuations in suspended solids in the effluent, maintaining a stable effective flow area on the irregular platform filter surface and reducing the frequency of filter layer disassembly and replacement.

[0009] This invention, through the setting of a starting component, a filtration component, and a central component, enables the moving block to drive the carrier frame and the cleaning frame to move up and down synchronously, so that the cleaning frame is in full contact with the inner wall of the wastewater cylinder and scrapes back and forth, removing the plastic debris and mold release agent oil stains mixed with the scale layer adhering to the cylinder wall and dropping them onto the surface of the irregular platform. This avoids the impurities accumulated on the wall from falling off in pieces due to the impact of incoming water and liquid level fluctuations, further ensuring the stability of the cleanliness of the effluent.

[0010] This invention uses a moving column that moves up and down with the moving block to cause the sealing gasket to reciprocate and compress inside the sealing cylinder. Airflow is pumped into the wastewater through the guide pipe to create disturbance. This, combined with the downward pressure of the filter plate, pushes the water flow to impact the irregularly shaped filter surface, accelerating the settling of suspended lightweight plastic debris in the water onto the filter surface, improving the solid-liquid separation rate, and increasing the wastewater treatment capacity per unit time of the tooling.

[0011] This invention uses a filter plate to pre-filter and retain large-diameter plastic burrs and debris, and combines this with a specially shaped mesh for fine filtration of micron-sized plastic powder, forming a two-stage gradient filtration system. This system progressively retains plastic solid impurities of different particle sizes, reducing the processing load on the lower fine filter layer, delaying the clogging cycle, and improving the overall filtration accuracy and effluent quality.

[0012] This invention uses the rotating linkage of the first and second turntables to drive the scraper to reciprocate along the arc surface of the irregular platform. With the help of the spring-driven lifting column, the scraper always adaptively adheres to the arc surface of the irregular platform, sweeping the scattered plastic impurities to the lowest end of the irregular platform and achieving centralized collection of the impurities, which greatly reduces the workload and difficulty of cleaning.

[0013] This invention utilizes the interlocking mechanism between the support frame slot and the clip, combined with the plug-in locking structure, to enable the cleaning frame and filter plate to be quickly disassembled and replaced by inserting and removing the plug and clip, without disassembling the main tooling structure. This simplifies the maintenance process for vulnerable parts and reduces downtime for maintenance. Attached Figure Description

A connecting rod 12 is fixedly connected between the two moving blocks 11, and a positioning sleeve 30 is fixedly connected to the outer side of the connecting rod 12. The bottom of the connecting strip 29 is fixedly connected to the positioning sleeve 30. The wastewater cylinder 1 is internally fixed... A filter table 43 is connected to the filter, and a collection component for treating plastic impurities in the wastewater from the washing of double-layer limited plastic pins is provided on the filter table 43. The collection component contains a lifting column 39 and a scraper 42. The plastic impurities can be collected by the cooperation of the lifting column 39 and the scraper 42. The collection component contains a shaped platform 44, which is fixedly connected to the bottom of the filter table 43. Each first turntable 9 and each second turntable 10 has a support strip 17 fixedly connected to its outer side. Each support strip 17 has a support rod 18 fixedly connected to its end away from the corresponding turntable. Several limiting cylinders 51 are fixedly connected to the bottom of each support rod 18. A lifting column 39 is inserted into each limiting cylinder 51. Each limiting cylinder 51 has a baffle plate 40 inside.Each stop plate 40 is fixedly connected to a corresponding lifting column 39. Each limiting cylinder 51 has a spring 41 inside, with both ends of each spring 41 fixedly connected to the inner wall of the corresponding limiting cylinder 51 and the stop plate 40, respectively. The end of each lifting column 39 away from the stop plate 40 is fixedly connected to a scraper 42. The irregularly shaped platform 44 has several small mesh holes for filtering plastic impurities, and the platform is semi-circular. Each scraper 42 is attached to the inner wall of the platform. A bearing plate 32 is provided inside the centralized assembly, with both ends of the bearing plate 32 fixedly connected to two support columns 8, respectively. A support arm 33 is fixedly connected to the outer side of the bearing plate 32, and an actuating cylinder 37 is fixedly connected to the top of the support arm 33. A telescopic column 35 is inserted into each actuating cylinder 37, and a telescopic column 35 is sleeved on the outer side of each telescopic column 35. The tension spring 38 and the trigger cylinder 37 are equipped with a support plate 36 inside. Each telescopic column 35 is fixedly connected to a support plate 36. Both ends of each tension spring 38 are fixedly connected to the corresponding support plate 36 and the inner wall of the trigger cylinder 37, respectively. A retractable block 34 is fixedly connected to the end of each telescopic column 35 away from the support plate 36. A trigger block 31 is fixedly connected to the outside of the positioning sleeve 30. When the trigger block 31 moves to the position corresponding to the retractable block 34, the trigger block 31 and the retractable block 34 are in contact. The first push bar 14 and the second push bar 15 on the outside of each connecting frame 13 are distributed crosswise. The support bars 17 on the outside of each first turntable 9 are in the same position. The support bars 17 on the outside of each second turntable 10 are in the same position. The support bars 17 on the outside of the first turntable 9 and the support bars 17 on the outside of the second turntable 10 are distributed crosswise. like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, when the double-layer limiting plastic pin cleaning fixture finishes cleaning the plastic pins, the plastic pin cleaning wastewater is introduced from the plastic pin cleaning fixture into the reducing flange pipe 4. Then, the ball valve on the reducing flange pipe 4 is opened, and the plastic pin cleaning wastewater flows from the reducing flange pipe 4 into the interior of the wastewater cylinder 1. Then, the plastic impurities in the plastic pin cleaning wastewater adhere to the inner wall of the irregular platform 44. Then, the motor 25 is started, and the motor 25 drives the threaded column 26 to rotate. When the threaded column 26 rotates, it drives the threaded block 28 to move towards the bottom of the placement shell 27. When the threaded block 28 moves, it drives the connecting strip. 29 moves, and when the connecting bar 29 moves, it pushes the positioning sleeve 30 to move. When the positioning sleeve 30 moves, it drives the connecting rod 12 to move. When the connecting rod 12 moves, it drives the two moving blocks 11 to move towards the bottom of the wastewater cylinder 1. When the moving blocks 11 move, they drive the corresponding connecting frame 13 to move. When the connecting frame 13 moves, it squeezes the first push bar 14 and the second push bar 15 to expand along the cylindrical part of the connecting frame 13. Then, the first push bar 14 and the second push bar 15 drive the first turntable 9 and the second turntable 10 to rotate and expand along the support column 8 through the touch plate 16. In this way, the support column 8 and When the first turntable 9 rotates, it drives the corresponding support bar 17 to rotate as well. Since both the support bar 17 and the touch plate 16 are V-shaped, when the touch plate 16 expands, each support bar 17 rotates and contracts. When the support bar 17 rotates and contracts, it drives the support rod 18 to move synchronously. Then, the support rod 18 drives the corresponding limiting cylinder 51 to move. When the limiting cylinder 51 moves, it drives the lifting column 39 to move. When the lifting column 39 moves, it drives the two scraper bars 42 to move along the inner wall of the irregular platform 44. Since the scraper bars 42 are initially located at the top of the inner wall of the irregular platform 44, and the lifting column 39 enters into... Inside the limiting cylinder 51, the spring 41 is in a compressed state. As the scraper 42 moves along the irregular platform 44, which is semi-arc, the scraper 42 moves the lifting column 39. The compressed spring then causes the spring 41 to rebound, and the spring 41 rebounds, causing the lifting column 39 to move. The lifting column 39 moves the scraper 42 to always be in contact with the inner wall of the irregular platform 44. Then, the motor 25 rotates in both directions, causing the threaded column 26 to rotate repeatedly. As the scraper 42 moves, it scrapes the plastic impurities attached to the irregular platform 44 towards the bottom of the irregular platform 44.

[0018] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the movable block 11 is equipped with a filtration assembly for cooperating with the start-up component. The filtration assembly contains a cleaning frame 45 and a filter plate 47. The cooperation of the cleaning frame 45 and the filter plate 47 promotes the flow of wastewater from the double-layer limiting plastic pin cleaning process. The filtration assembly contains two sealing cylinders 19, each fixedly connected to the bottom of the support block 7. Each sealing cylinder 19 has a movable column 21 inserted into it, and each sealing cylinder 19 has a sealing gasket 20 inside. Each movable column 21 is fixedly connected to its corresponding sealing gasket 20, and the end of each movable column 21 away from the sealing gasket 20 is fixedly connected to its corresponding movable block 11. The sealing cylinder 19 has two actuation holes, and a guide is fixedly connected to the outside of each actuation hole. The filter assembly in the pipe 22 has four support frames 46, and two fixed blocks 23 are fixedly connected to the outside of each moving block 11. Each fixed block 23 is fixedly connected to a support frame 46. A filter plate 47 is provided between each pair of support frames 46 on opposite sides, and the filter plate 47 is fixedly connected to the two corresponding support frames 46. Each support frame 46 has a slot for placing a clip 48, and a clip 48 is engaged in the slot of each support frame 46. Two plugs 49 are inserted into each support frame 46, and each plug 49 passes through the corresponding clip 48. A cleaning frame 45 is provided on the outside of each of the four clips 48, and the cleaning frame 45 is fixedly connected to the four clips 48. The cleaning frame 45 is in contact with the inner wall of the wastewater cylinder 1. like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, when the plastic pin cleaning wastewater is inside the wastewater cylinder 1, and the moving block 11 moves, it drives the moving column 21 to move towards the bottom of the sealing cylinder 19. The moving column 21, while moving, causes the sealing gasket 20 to press down. When the sealing gasket 20 presses down, it discharges the air inside the sealing cylinder 19 along the two guide pipes 22 on the outside of the sealing cylinder 19. The pressure generated when the guide pipes 22 discharge further accelerates the movement of the plastic pin cleaning wastewater inside the wastewater cylinder 1. This movement of the plastic pin cleaning wastewater promotes the cleaning of the plastic pins... Plastic impurities inside the water tank fall into the inner wall of the shaped platform 44. As the moving block 11 moves, it drives the corresponding support frame 46 to move as well. The support frame 46, through the locking strip 48, moves the cleaning frame 45. The cleaning frame 45 scrapes off the plastic impurities adhering to the inner wall of the wastewater tank 1, causing them to fall into the inner wall of the shaped platform 44. When the cleaning frame 45 needs to be replaced, the insertion of the bolt 49 into the support frame 46 is released, as is the locking strip 48 into the support frame 46. The support frame 46 is then removed for replacement. When the support frame 46 descends, it drives the filter plate 47 to move synchronously. During this movement, the filter plate 47 intercepts large particles of impurities in the plastic pin cleaning wastewater. Furthermore, the filter plate 47 presses down, pushing the plastic pin cleaning wastewater inside the wastewater cylinder 1 towards the inner wall of the shaped platform 44. Consequently, the plastic pin cleaning wastewater, pushed by the filter plate 47, accelerates its impact against the inner wall of the shaped platform 44, leading to faster separation. When the positioning sleeve 30 descends, it drives the trigger block 31 to move towards the position of the retracting block 34. When the trigger block 31 moves to the position corresponding to the retracting block 34, the retracting block 34 is squeezed by the trigger block 31 and drives the telescopic column 35 to move towards the inside of the trigger cylinder 37. Then, the telescopic column 35 drives the bearing plate 36 to continuously hit the inner wall of the trigger cylinder 37 and generate vibration. The tension spring 38 is stretched. When the trigger block 31 leaves the position corresponding to the retracting block 34, the stretched tension spring 38 drives the bearing plate 36 to reset. The continuous vibration generated promotes the shaking of plastic impurities on the irregular platform 44 and prevents the small round hole of the irregular platform 44 from being blocked by plastic impurities.

[0019] Working principle: Step 1, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, when the double-layer limiting plastic pin cleaning fixture finishes cleaning the plastic pins, the plastic pin cleaning wastewater is introduced from the plastic pin cleaning fixture into the reducing flange pipe 4. Then, the ball valve on the reducing flange pipe 4 is opened, and the plastic pin cleaning wastewater flows from the reducing flange pipe 4 into the interior of the wastewater cylinder 1. Then, the plastic impurities in the plastic pin cleaning wastewater adhere to the inner wall of the irregular platform 44. Then, the motor 25 is started, and the motor 25 drives the threaded column 26 to rotate. When the threaded column 26 rotates, it drives the threaded block 28 to move towards the bottom of the placement shell 27. When the threaded block 28 moves, it drives the connecting strip. 29 moves, and when the connecting bar 29 moves, it pushes the positioning sleeve 30 to move. When the positioning sleeve 30 moves, it drives the connecting rod 12 to move. When the connecting rod 12 moves, it drives the two moving blocks 11 to move towards the bottom of the wastewater cylinder 1. When the moving blocks 11 move, they drive the corresponding connecting frame 13 to move. When the connecting frame 13 moves, it squeezes the first push bar 14 and the second push bar 15 to expand along the cylindrical part of the connecting frame 13. Then, the first push bar 14 and the second push bar 15 drive the first turntable 9 and the second turntable 10 to rotate and expand along the support column 8 through the touch plate 16. In this way, the support column 8 and When the first turntable 9 rotates, it drives the corresponding support bar 17 to rotate as well. Since both the support bar 17 and the touch plate 16 are V-shaped, when the touch plate 16 expands, each support bar 17 rotates and contracts. When the support bar 17 rotates and contracts, it drives the support rod 18 to move synchronously. Then, the support rod 18 drives the corresponding limiting cylinder 51 to move. When the limiting cylinder 51 moves, it drives the lifting column 39 to move. When the lifting column 39 moves, it drives the two scraper bars 42 to move along the inner wall of the irregular platform 44. Since the scraper bars 42 are initially located at the top of the inner wall of the irregular platform 44, and the lifting column 39 enters into... Inside the limiting cylinder 51, the spring 41 is in a compressed state. As the scraper 42 moves along the irregular platform 44, since the irregular platform 44 is semi-arc, the scraper 42 moves and drives the lifting column 39 to move. The compressed spring then causes the spring 41 to rebound. When the spring 41 rebounds, it drives the lifting column 39 to move. When the lifting column 39 moves, it drives the scraper 42 to always be in contact with the inner wall of the irregular platform 44. Then, the motor 25 rotates in both directions to make the threaded column 26 rotate repeatedly. When the scraper 42 moves, it scrapes the plastic impurities attached to the irregular platform 44 towards the bottom of the irregular platform 44. Step 2, as follows Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, when the plastic pin cleaning wastewater is inside the wastewater cylinder 1, and the moving block 11 moves, it drives the moving column 21 to move towards the bottom of the sealing cylinder 19. The moving column 21, while moving, causes the sealing gasket 20 to press down. When the sealing gasket 20 presses down, it discharges the air inside the sealing cylinder 19 along the two guide pipes 22 on the outside of the sealing cylinder 19. The pressure generated when the guide pipes 22 discharge further accelerates the movement of the plastic pin cleaning wastewater inside the wastewater cylinder 1. This movement of the plastic pin cleaning wastewater promotes the cleaning of the plastic pins... Plastic impurities inside the water tank fall into the inner wall of the shaped platform 44. As the moving block 11 moves, it drives the corresponding support frame 46 to move as well. The support frame 46, through the locking strip 48, moves the cleaning frame 45. The cleaning frame 45 scrapes off the plastic impurities adhering to the inner wall of the wastewater tank 1, causing them to fall into the inner wall of the shaped platform 44. When the cleaning frame 45 needs to be replaced, the insertion of the bolt 49 into the support frame 46 is released, as is the locking strip 48 into the support frame 46. The support frame 46 is then removed for replacement. When the support frame 46 descends, it drives the filter plate 47 to move synchronously. During this movement, the filter plate 47 intercepts large particles of impurities in the plastic pin cleaning wastewater. Furthermore, the filter plate 47 presses down, pushing the plastic pin cleaning wastewater inside the wastewater cylinder 1 towards the inner wall of the shaped platform 44. Consequently, the plastic pin cleaning wastewater, pushed by the filter plate 47, accelerates its impact against the inner wall of the shaped platform 44, leading to faster separation. When the positioning sleeve 30 descends, it drives the trigger block 31 to move towards the position of the retracting block 34. When the trigger block 31 moves to the position corresponding to the retracting block 34, the retracting block 34 is squeezed by the trigger block 31 and drives the telescopic column 35 to move towards the inside of the trigger cylinder 37. Then, the telescopic column 35 drives the bearing plate 36 to continuously hit the inner wall of the trigger cylinder 37 and generate vibration. The tension spring 38 is stretched. When the trigger block 31 leaves the position corresponding to the retracting block 34, the stretched tension spring 38 drives the bearing plate 36 to reset. The continuous vibration generated promotes the shaking of plastic impurities on the irregular platform 44 and prevents the small round hole of the irregular platform 44 from being blocked by plastic impurities.
