Description

Technical Field

[0001] The present invention relates to the technical field of multi-stage wastewater treatment, and particularly to a multi-stage wastewater treatment device for the production of silicone rubber products based on environmental protection promotion. Background Art

[0002] During the production of silicone rubber products, a large amount of wastewater is generated, so wastewater treatment equipment is required for treatment.

[0003] However, in the prior art, due to the presence of floating substances such as debris particles in the wastewater generated during the production of silicone rubber products, the integrated wastewater treatment equipment usually performs multi-stage treatment through multiple steps such as sedimentation, grid filtration, aerobic and anaerobic treatment. Larger particle debris will precipitate in the sedimentation tank and be blocked and intercepted by the grid during overflow. However, there are still larger debris and small particles entering the next-stage aerobic treatment area. In the aerobic area, mainly through the aeration disk at the bottom, when compressed air is transported to the aeration disk through a pipeline, the air will escape from these tiny pores and come into contact with water. The small particle debris existing in the wastewater will enter the aeration system along with the water flow. These debris may continuously deposit and adhere to the pores of the pipeline and the aeration disk, gradually blocking the aeration disk, resulting in the inability of air to be evenly discharged from the aeration disk, reducing the oxygen transfer efficiency in the aeration tank, and then reducing the wastewater treatment effect. Furthermore, only the equipment can be cleaned and maintained. At the same time, because multiple aeration disks need to be set and their shapes are irregular, only cleaning equipment can be installed on the side wall of the aerobic area for local treatment. However, the particles after cleaning still stay in the aerobic area, and the particles falling into the aerobic area cannot be effectively collected, resulting in the inability to effectively automatically clean the precipitated particles, affecting wastewater treatment. Still, the device can only be maintained after suspension, and the efficiency and continuity of the device operation cannot be guaranteed. Summary of the Invention

[0004] The purpose of the present invention is to provide a multi-stage wastewater treatment device for the production of silicone rubber products based on environmental protection promotion, so as to solve the problems of insufficient wastewater treatment efficiency and continuity.

[0005] The technical solution of the present invention is as follows: A multi-stage wastewater treatment device for the production of silicone rubber products based on environmental protection promotion, including a box body, further including an aerator and a filter plate arranged inside the box body, a bushing slidably connected inside the box body, a scraping strip rotatably connected to the top of the bushing, a driving member arranged on one side inside the box body, a mounting plate fixedly connected inside the box body, and a blocking member, a sealing member and a receiving pipe fixedly connected to the mounting plate. The filter plate is located above the aerator, the scraping strip is located above the filter plate, the blocking member is located above the sealing member, and the sealing member is located above the receiving pipe. When the scraping strip does not contact the blocking member, the sealing member fits with the filter plate and closes the top of the receiving pipe at the same time. The bushing drives the scraping strip to move through the driving member, and the scraping strip accumulates particles above the sealing member. At the same time, the accumulated particles push the sealing member, so that the sealing member is briefly communicated with the receiving pipe.

[0006] Further, the bushing includes an arc groove sleeve slidably connected to the box body, a circular shaft fixedly connected inside the arc groove sleeve, and a first magnetic block and a second magnetic block fixedly connected inside the arc groove sleeve. Both the first magnetic block and the second magnetic block are provided with two and are symmetric about the central axis of the arc groove sleeve. The top end of the scraping strip is rotatably connected to the outside of the circular shaft.

[0007] Further, a blocking rod and a guiding rod are arranged inside the box body. The midline of the blocking rod coincides with the midline of the scraping strip. There are two guiding rods and they are symmetric about the central axis of the box body. Both ends of the arc groove sleeve are slidably connected to the outside of the guiding rod.

[0008] Further, the blocking member includes a hollow oblique block slidably connected inside the mounting plate, a telescopic rod connected between the hollow oblique block and the mounting plate, and a blocking sleeve fixedly connected to the telescopic rod.

[0009] Further, the sealing member includes a spring rod fixedly connected to the mounting plate, and an inclined baffle slidably connected to the outside of the spring rod. The top to bottom of both the hollow oblique block and the inclined baffle are inclined towards the filter plate.

[0010] Further, the first magnetic block is located in the inclined plane inside the arc groove sleeve, the second magnetic block is located in the vertical plane inside the arc groove sleeve, the magnetic forces of the first magnetic block and the second magnetic block are the same, and the elastic forces of the telescopic rod and the spring rod are both smaller than the adsorption force between the first magnetic block and the scraping strip.

[0011] Further, a top groove opening is provided at the top of the receiving pipe. A side plate is arranged on one side of the filter plate close to the inclined baffle. A plurality of return holes are equidistantly arranged on the side plate. The return holes are located above the bottom end of the inclined baffle. When the inclined baffle fits with the side plate, the top groove opening is blocked.

[0012] Further, the driving member includes a bidirectional lead screw and a blade rod rotatably connected to one side inside the box body, and a transmission belt connected between the bidirectional lead screw and the blade rod. One end of the blade rod is located inside the aerator. When the hollow inclined block fits with the barrier sleeve, the threaded section length of the bidirectional lead screw is greater than the distance between the blocking rod and the hollow inclined block. The bottom end of the scraping strip is set as a round bar, the bottom end of the round bar is smooth, and both ends of the round bar are attached to the inner wall of the box body. The round bar is located below the hollow inclined block, and the diameter of the round bar is equal to the distance from the bottom end of the hollow inclined block to the top of the filter plate.

[0013] Further, a double gear box is provided near the bidirectional lead screw of the box body, and one end of the bidirectional lead screw is located inside the double gear box.

[0014] Further, a vertical bar is provided at one end of the arc groove sleeve near the bidirectional lead screw, and the bottom end of the vertical bar is sleeved outside the bidirectional lead screw.

[0015] Advantages of the present invention: By treating wastewater in multiple stages, it is ensured that the wastewater can better meet the treatment requirements. At the same time, by setting a filter plate above the aerator as a protection, large particulate matter in the wastewater can be effectively intercepted, the particles entering the aerator can be reduced, the aeration disk blockage can be avoided, the overall water quality purification level can be effectively improved, and the scraping strip and the plugging member work together to realize the automatic cleaning and collection of particles, without frequent manual intervention, improve the cleaning efficiency, reduce the manual maintenance cost and the equipment downtime, and ensure the continuous and efficient operation of the device.

[0016] Due to the air flow power of the aerator, the driving member drives the shaft sleeve to realize the reciprocating movement of the scraping strip, automatically cleaning the particles on the surface of the filter plate. At the same time, when the particles accumulate to a certain extent, the plugging member can be automatically pushed to open, and the particles are discharged into the receiving pipe, reducing the power equipment, reducing the burden on the box body, automatically starting with the aerator, without frequent manual intervention, fully utilizing a simple mechanical structure, being able to be used for a long time in the wastewater area, cleaning the box body, extending the service life of the equipment, and improving the operation stability of the equipment.

[0017] 3. Through the cooperation of the scraping strip with different magnetic blocks and the barrier member, it is ensured that the particles are orderly accumulated on the filter plate. At the same time, an independent space is formed when the round bar fits with the hollow inclined block, effectively preventing the particles from diffusing with the water flow, ensuring the efficient collection of the particles, and using the spring rod to squeeze the inclined baffle, so that the inclined baffle is closely attached to the filter plate, preventing wastewater leakage, ensuring the independence of each functional area of the equipment, and making the equipment stable during operation.

[0020] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0021] Refer to Figures 1-9, This is an embodiment of the present invention, which provides a multi-stage wastewater treatment device for the production of silicone rubber products based on environmental protection promotion. It includes a box body 1, and also includes an aerator 2 and a filter plate 3 arranged inside the box body 1, a bushing 4 slidably connected inside the box body 1, a scraping bar 5 rotatably connected to the top of the bushing 4, a driving member 6 arranged on one side inside the box body 1, a mounting plate 7 fixedly connected inside the box body 1, and a blocking member 8, a plugging member 9 and a receiving pipe 10 fixedly connected to the mounting plate 7. The filter plate 3 is located above the aerator 2, the scraping bar 5 is located above the filter plate 3, the blocking member 8 is located above the plugging member 9, the plugging member 9 is located above the receiving pipe 10. When the scraping bar 5 does not contact the blocking member 8, the plugging member 9 fits with the filter plate 3 and closes the top of the receiving pipe 10 at the same time. The bushing 4 drives the scraping bar 5 to move through the driving member 6, and the scraping bar 5 accumulates particles above the plugging member 9. At the same time, the accumulated particles push the plugging member 9, so that the plugging member 9 is briefly interconnected with the receiving pipe 10, and the accumulated particles are discharged into the receiving pipe 10.

[0022] Among them, the middle part of the box body 1 is an aerobic zone, one side of the aerobic zone is a sedimentation zone, and the other side is an anaerobic zone. A grille is arranged between the sedimentation zone and the aerobic zone. The wastewater first enters the sedimentation zone, passes through the grille and then enters the aerobic zone, and finally enters the anaerobic zone. The aerator 2 is composed of a plurality of pipelines and a plurality of aeration discs combined.

[0023] Specifically, by placing the filter plate 3 above the filtering aerator 2 to intercept particles, it effectively reduces the particles entering the aerator 2 and avoids blockage of the aeration discs. At the same time, the scraping bar 5 timely cleans the particles on the surface of the filter plate 3 to avoid long-term accumulation of particles on the filter plate 3. At the same time, the scraping bar 5 is used to push the particles above the plugging member 9 for temporary storage. When too many particles accumulate above the plugging member 9, the scraping bar 5 uses the accumulated particles as a medium to squeeze the plugging member 9, causing the plugging member 9 to move. The upper part of the plugging member 9 is interconnected with the receiving pipe 10, and the particles on the top of the plugging member 9 and part of the wastewater are depressurized and then discharged into the receiving pipe 10. When the particles are quickly discharged, the plugging member 9 fits with the filter plate 3 again under its own elastic force and quickly closes the top of the receiving pipe 10, thus avoiding a large amount of particles accumulating in the box body 1 and ensuring the maintenance of the aerator 2 at the same time.

[0024] Refer to Figures 3-6 , The bushing 4 includes an arc groove sleeve 41 slidably connected to the box body 1, a circular shaft 42 fixedly connected inside the arc groove sleeve 41, and a first magnet 43 and a second magnet 44 fixedly connected inside the arc groove sleeve 41. Both the first magnet 43 and the second magnet 44 are provided with two and are symmetric about the central axis of the arc groove sleeve 41. The top of the scraping bar 5 is rotatably connected to the outside of the circular shaft 42.

[0025] Specifically, the arc groove sleeve 41 has a long strip-shaped arc on its outer surface, and the groove is a short arc. The two ends of the arc groove sleeve 41 are restricted by the guide rods 102. Thus, the groove part is divided into two surfaces, namely the inclined surface and the vertical surface. At the same time, the arc groove sleeve 41 is a component that drives the scraper strip 5 to move stably. The surface of the scraper strip 5 must be made of a metal material so that it can adsorb to the first magnet 43 and the second magnet 44. Each pair of magnets is symmetrically distributed about the central axis of the arc groove sleeve 41 and can adsorb both sides of the scraper strip 5 to ensure the stability of the scraper strip 5. Then, the arc groove sleeve 41 slides in the box body 1, driving the round shaft 42 and the scraper strip 5 to move synchronously. The scraper strip 5 scrapes and cleans the surface of the filter plate 3 under the support of the round shaft 42.

[0026] Referring to Figures 3-6 , a blocking rod 101 and guide rods 102 are arranged inside the box body 1. The midline of the blocking rod 101 coincides with the midline of the scraper strip 5. There are two guide rods 102 and they are symmetric about the central axis of the box body 1. During the reciprocating movement of the scraper strip 5 along with the shaft sleeve 4, the blocking rod 101 plays a role in limiting and guiding the scraper strip 5 to ensure that the scraper strip 5 can swing, enabling the particles to accurately accumulate at the specified position. The two ends of the arc groove sleeve 41 are slidably connected to the outside of the guide rods 102, and the guide rods 102 guide the arc groove sleeve 41, causing the arc groove sleeve 41 to only move along the path of the guide rods 102. The guide rods 102 are slender cylindrical, and both ends are bolted to the inner wall of the box body 1 through flange plates to ensure firm and reliable installation. The two ends of the arc groove sleeve 41 are provided with collar rings adapted to the guide rods 102.

[0027] Referring to Figures 3-7 , the blocking member 8 includes a hollow inclined block 81 slidably connected inside the mounting plate 7, a telescopic rod 82 connected between the hollow inclined block 81 and the mounting plate 7, and a blocking sleeve 83 fixedly connected to the telescopic rod 82.

[0028] The blocking member 9 includes a spring rod 91 fixedly connected to the mounting plate 7 and an inclined baffle 92 slidably connected to the outside of the spring rod 91. The top to the bottom of the hollow inclined block 81 and the inclined baffle 92 are inclined towards the direction close to the filter plate 3, so that the particles accumulate along the surface of the inclined baffle 92.

[0029] Specifically, under the elastic force of the spring rod 91, the inclined baffle 92 is in close contact with the filter plate 3 to form an effective seal. At the same time, on the mating surface between the inclined baffle 92 and the filter plate 3, a silica gel strip is fixedly connected through glue, reducing component collision damage and strengthening the sealing effect, and can completely block the wastewater from entering the inside of the receiving pipe 10.

[0030] In addition, when the scraping bar 5 accumulates particles above the inclined baffle 92, as the weight of the particles continuously increases and the accumulation becomes compact, when there are too many accumulated particles, the bottom end of the scraping bar 5 will use the compacted particles as a medium during movement, causing the inclined baffle 92 to be pushed and the spring rod 91 to be compressed. The sealing surface between the inclined baffle 92 and the filter plate 3 is opened, and the particles quickly fall into the receiving pipe 10 under the action of gravity pressure. When the particles decrease, as the medium between the scraping bar 5 and the inclined baffle 92 decreases, the inclined baffle 92 quickly resets by the elasticity of the spring rod 91, re - fits with the side plate 31, seals the top slot 11, and prevents wastewater from entering the receiving pipe 10, ensuring the independence and operational stability of each functional area of the equipment.

[0031] Refer to Figures 3-7 , the first magnetic block 43 is located in the inclined plane inside the arc groove sleeve 41, the second magnetic block 44 is located in the vertical plane inside the arc groove sleeve 41, the magnetic forces of the first magnetic block 43 and the second magnetic block 44 are the same, and the elastic forces of the telescopic rod 82 and the spring rod 91 are both less than the adsorption force between the first magnetic block 43 and the scraping bar 5. At the same time, two telescopic rods 82 and spring rods 91 can be set, and the sum of their elastic forces is still less than the magnetic force of the first magnetic block 43.

[0032] Among them, the telescopic rod 82 and the spring rod 91 have the same structure. When the first magnetic block 43 adsorbs the scraping bar 5, the scraping bar 5 is in an inclined state, while when the scraping bar 5 adsorbs the second magnetic block 44, it is in a vertical state.

[0033] Specifically, when the scraping bar 5 pushes the particles to accumulate above the inclined baffle 92, at this time, the scraping bar 5 is adsorbed perpendicular to the second magnetic block 44. When the scraping bar 5 contacts the hollow inclined block 81, since the magnetic force of the second magnetic block 44 is greater than that of the telescopic rod 82, when the scraping bar 5 moves at this time, the scraping bar 5 will squeeze the hollow inclined block 81, causing the hollow inclined block 81 to compress the telescopic rod 82 until the hollow inclined block 81 contacts the blocking sleeve 83. Then, the blocking sleeve 83 is restricted and cannot move. However, at this time, since the scraping bar 5 will continue to move with the arc groove sleeve 41, the scraping bar 5 will be blocked by the blocking sleeve 83 and thus generate displacement and rotation. When the scraping bar 5 and the hollow inclined block 81 move synchronously, the scraping bar 5 will accumulate the particles. If the accumulation is already compact, at this time, the particles will be used to push the inclined baffle 92, and then the inclined baffle 92 will also compress the spring rod 91 when it moves.

[0034] Refer to Figures 3-8 , a top slot 11 is opened at the top of the receiving pipe 10, a side plate 31 is provided on one side of the filter plate 3 close to the inclined baffle 92, and a plurality of return holes 311 are equidistantly opened on the side plate 31. The return holes 311 are located above the bottom end of the inclined baffle 92. When the inclined baffle 92 fits with the side plate 31, the top slot 11 is blocked.

[0035] Specifically, the top groove opening 11 formed at the top of the storage tube 10 is designed with a rectangular opening, which can ensure that the particles smoothly fall into the storage tube 10. One end of the storage tube 10 is connected to an external suction device, which can clean the particles inside the storage tube 10.

[0036] In addition, the position of the return hole 311 is above the bottom end of the inclined baffle 92. When the bottom end of the scraping bar 5 squeezes and accumulates the particles, the particles will be deposited above the inclined baffle 92. Since the particles are squeezed, the space of the waste water is compressed. At this time, the waste water will leave the upper part of the inclined baffle 92 from the return hole 311, avoiding the situation that the waste water has no moving space, which may cause the scraping bar 5 to directly push the inclined baffle 92 by using the waste water, and thus preventing the waste water from entering the storage tube 10 through the top groove opening 11. At the same time, when the top groove opening 11 is opened, due to the gravity of the particles, they will quickly fall into the storage tube 10 from the top groove opening 11, thereby reducing the amount of waste water entering the storage tube 10.

[0037] Refer to Figures 3-8 , the driving member 6 includes a bidirectional lead screw 61 and a blade rod 62 rotatably connected to one side inside the box body 1, and a transmission belt 63 connected between the bidirectional lead screw 61 and the blade rod 62. One end of the blade rod 62 provided with blades is located inside the aerator 2. When the hollow inclined block 81 fits with the barrier sleeve 83, the length of the threaded section of the bidirectional lead screw 61 is greater than the distance between the blocking rod 101 and the hollow inclined block 81.

[0038] In addition, the blade rod 62 is composed of a shaft rod and a plurality of blades. The plurality of blades are arranged at equal angles at one end of the shaft rod.

[0039] Among them, the threaded section of the bidirectional lead screw 61 represents the area where the arc groove sleeve 41 moves. When the hollow inclined block 81 is in contact with the barrier sleeve 83, the hollow inclined block 81 will be restricted by the barrier sleeve 83 and unable to move. At the same time, the blocking rod 101 always remains in a fixed position. Then, since the length of the threaded section of the bidirectional lead screw 61 is greater than the distance between the blocking rod 101 and the hollow inclined block 81, and the arc groove sleeve 41 drives the scraping strip 5 to move synchronously when it moves, when the hollow inclined block 81 cannot move, the scraping strip 5 still moves with the arc groove sleeve 41. If the scraping strip 5 moves towards the hollow inclined block 81, the scraping strip 5 at this time will be squeezed by the fixed hollow inclined block 81, and then separated from the second magnetic block 44. At the same time, the scraping strip 5 will rotate with the center of the circular shaft 42 as the fulcrum, and one side of it will adsorb with the first magnetic block 43. Due to the rotation of the scraping strip 5, the bottom end of it will no longer contact the top surface of the filter plate 3. Then, when the scraping strip 5 moves back, it will not push the particles intercepted by the filter plate 3 to a position far from the plugging member 9. At the same time, when the scraping strip 5 moves back, it is affected by the blocking of the blocking rod 101, and then separated from the first magnetic block 43, and at the same time rotates back and adsorbs with the second magnetic block 44. Then, the bottom of the scraping strip 5 contacts the top surface of the filter plate 3 again, so that the particles on the top of the filter plate 3 can be pushed by the scraping strip 5 above the plugging member 9. At this time, only a small amount of particles stay near the blocking rod 101 on the filter plate 3, effectively piling up and storing the particles in a single area, while reducing the equipment pressure, thereby restricting the movement path of the scraping strip 5, making the particle piling process more orderly, reducing the uncertainty in the particle piling process, and ensuring the smoothness and efficiency of the particle cleaning process.

[0040] A vertical strip 411 is provided at one end of the arc groove sleeve 41 close to the bidirectional lead screw 61. The bottom end of the vertical strip 411 is sleeved outside the bidirectional lead screw 61. When the bidirectional lead screw 61 rotates, it will drive the vertical strip 411 to move synchronously, and the bidirectional lead screw 61 can control the vertical strip 411 to move reciprocally.

[0041] Specifically, one end of the blade rod 62 where the blade is provided is located inside the aerator 2, and its blade position is mainly located at the pipeline position of the aerator 2. When the air flows in the pipeline, affected by the unidirectional aerodynamic force, the blade will rotate, and then the whole blade rod 62 will also rotate accordingly. If it is necessary to control the rotation direction of the blade rod 62, its center position can be set at the upper part of the width, that is, the gap between the bottom of the blade of the blade rod 62 and the inner wall of the pipeline is larger, so that the air flows from the lower part first when flowing, and then the unidirectional rotation of the blade rod 62 can be controlled.

[0042] The bottom end of the scraping strip 5 is set as a round strip 51, the bottom end of the round strip 51 is smooth, both ends of the round strip 51 are in contact with the inner wall of the box body 1, the round strip 51 is located below the hollow inclined block 81, and the diameter of the round strip 51 is equal to the distance from the bottom end of the hollow inclined block 81 to the top of the filter plate 3. At the same time, at one end of the hollow inclined block 81 close to the filter plate 3, when the spring on the telescopic rod 82 is not compressed, it is within the top surface area of the filter plate 3. Therefore, when the round strip 51 enters between the hollow inclined block 81 and the filter plate 3, this area will be blocked, and only the return hole 311 is connected to the outside, so that the pushed gravel can only be squeezed above the inclined baffle 92, preventing a large number of particles from separating from this area with the compressed water flow due to compression, and effectively piling up the particulate matter.

[0043] Referring to Figures 1-9 , a double gear box 103 is provided at the box body 1 near the bidirectional lead screw 61. One end of the bidirectional lead screw 61 is located inside the double gear box 103. Two meshing helical gears are provided inside the double gear box 103, that is, one end of the bidirectional lead screw 61 is connected to the helical gear inside the double gear box 103. Furthermore, according to requirements, a motor can be set, the motor is connected to the other helical gear inside the double gear box, and the motor can directly drive the bidirectional lead screw 61 to ensure continuous rotational power.

[0044] The working principle of the present invention is as follows: The wastewater first flows into the sedimentation area of the box body 1. Under the action of gravity, larger particulate matter naturally settles to the bottom of the sedimentation area. Subsequently, the preliminarily sedimented wastewater passes through the grid filtering device between the sedimentation area and the aerobic area, effectively intercepting most of the larger-sized particles, reducing the subsequent treatment pressure, and entering the aerobic area. The aerator 2 conveys compressed air through the pipeline to the aeration disc, and the compressed air escapes from the tiny air holes of the aeration disc and is fully mixed with the wastewater. The filter plate 3 located above the aerator 2 intercepts the remaining particles in the wastewater to prevent them from entering the aerator 2. The particles intercepted by the filter plate 3 will gradually accumulate on its surface. At this time, when the air flows in the pipeline, under the influence of the unidirectional air power, the blade drives the leaf rod 62 to rotate, and the leaf rod 62 transmits the power to the bidirectional lead screw 61 through the transmission belt 63, causing the bidirectional lead screw 61 to start rotating. When the bidirectional lead screw 61 rotates, the vertical strip 411 sleeved thereon drives the arc groove sleeve 41 to perform a reciprocating linear motion along the guide rod 102, and the movement of the arc groove sleeve 41 drives the round shaft 42 and the scraping strip 5 to move synchronously. During the movement of the scraping strip 5.

[0045] Since the state of the scraping strip 5 no longer changes when the device is turned off and will not be adjusted when restarted, whether the state of the scraping strip 5 is inclined, vertical, or in a changing state cannot be determined, but it will not affect the use of the device. Taking the scraping strip 5 in a vertical state and moving towards the plugging member 9 as an example, at this time, the round bar 51 at the bottom end of the scraping strip 5 will contact the surface of the filter plate 3, and gradually push the particles intercepted by the filter plate 3 towards the plugging member 9. When the scraping strip 5 pushes the particles below the hollow inclined block 81, due to the magnetic force of the first magnet 43 and the second magnet 44 being greater than the elastic force of the telescopic rod 82, the scraping strip 5 will squeeze the hollow inclined block 81 when it continues to move, causing it to compress the telescopic rod 82. When the hollow inclined block 81 fits with the blocking sleeve 83, its movement is restricted, and the arc groove sleeve 41 continues to drive the scraping strip 5 to move. Blocked by the blocking sleeve 83, the scraping strip 5 rotates with the center of the round shaft 42 as the fulcrum. During the rotation process, the scraping strip 5 separates from the second magnet 44, and one side of it adsorbs to the first magnet 43, and the bottom end no longer contacts the top surface of the filter plate 3. Then when the scraping strip 5 moves back, it will not push the particles to a position far from the plugging member 9. When the scraping strip 5 moves back, it is blocked by the blocking rod 101, separates from the first magnet 43, and re-adsorbs to the second magnet 44, and the bottom contacts the top surface of the filter plate 3 again, continuing to push the particles to accumulate above the inclined baffle 92. As the particles continue to accumulate, when the quantity and the degree of accumulation reach a certain level, the scraping strip 5 uses the accumulated particles as a medium to push the inclined baffle 92. The inclined baffle 92 compresses the spring rod 91, causing the sealing surface between the inclined baffle 92 and the filter plate 3 to open. Under the action of gravity and pressure, the particles quickly pass through the top slot 11 along the inclined channel and fall into the receiving pipe 10. When the particle discharge is completed, the inclined baffle 92 quickly resets by relying on the elasticity of the spring rod 91, and the inclined baffle 92 fits with the filter plate 3 again, plugging the top slot 11 to prevent wastewater from entering the receiving pipe 10, ensuring the independence and operation stability of each functional area of the device, effectively cleaning the inside of the box body 1, and ensuring the effective treatment of wastewater.
