Description

Technical Field

[0001] This application relates to the technical field of pipeline wastewater recycling, and in particular to a PSA water ring vacuum pump mechanical seal flushing water recycling system. Background Technology

[0002] In modern industrial production, PSA water ring vacuum pumps are widely used as important equipment in various fields, including chemical, pharmaceutical, food processing, and electronics manufacturing. However, during operation, the mechanical seal of the vacuum pump operates in extremely harsh environments, needing to withstand high temperatures and the erosion of various corrosive gases or liquids.

[0003] To improve the service life of mechanical seals and the operating efficiency of pumps, and to ensure the sealing of the connection between the pump and the pipeline, flushing water is usually used to cool and protect the mechanical seals. Traditionally, flushing water is directly discharged into the environment after use, which not only wastes water resources but also has adverse effects on the environment.

[0004] For example, a BDO plant mechanical seal flushing water recycling system, disclosed in CN212212399U, has significant beneficial effects. Firstly, by recycling and reusing the mechanical seal flushing water, it greatly reduces the consumption of fresh water resources, lowers water costs in production, and reduces wastewater discharge, aligning with the concept of energy conservation and environmental protection. Secondly, the system is equipped with two transfer pumps, which can serve as backups for each other, effectively preventing system shutdowns due to single pump failures, ensuring the continuity of mechanical seal flushing water supply, and thus ensuring the safe and stable operation of the mechanical seals in the BDO plant, improving the overall system reliability.

[0005] During long-term operation, mechanical seals inevitably accumulate a layer of dirt on their surface due to factors such as media residue and wear debris. Although the existing technologies mentioned above can achieve the recycling of flushing water for vacuum pump mechanical seals, there are still significant shortcomings in practical applications: when flushing water cleans the surface of the mechanical seal, the attached dirt is washed off and mixed into the flushing water, and the existing technologies do not have an effective removal mechanism for these impurities mixed into the water.

[0006] This results in a large amount of impurities remaining in the recycled flushing water, which not only reduces the cleaning ability of subsequent flushing but may also cause secondary wear on the mechanical seal during circulation, or even block pipelines or equipment components, seriously affecting the efficiency and actual effect of flushing water recycling.

[0007] Based on this, as stated above, there is still room for improvement in the existing technology for recycling mechanical seal flushing water. Summary of the Invention

[0008] To address the aforementioned technical problems, this application provides a PSA water ring vacuum pump mechanical seal flushing water recycling system, employing the following technical solution: A PSA water ring vacuum pump mechanical seal flushing water recycling system includes a hollow treatment tank. A drain pipe is installed through the top of the treatment tank. A protruding structure is provided on the side wall of the treatment tank away from the drain pipe, and an inlet pipe is installed through the protruding structure. An arc-shaped plate and a filter mechanism that cooperates with the arc-shaped plate are installed inside the treatment tank. The filter mechanism includes:

[0009] The filter frame is installed inside the treatment chamber and located between the inlet pipe and the arc plate.

[0010] The conveying assembly, installed inside the processing tank and located between the filter frame and the inlet pipe, conveys the dirt filtered by the filter frame to the outside.

[0011] The cleaning component, installed inside the treatment tank and located between the drain pipe and the filter frame, cleans the dirt on the filter frame.

[0012] Preferably, the conveying assembly includes a through slot opened on the higher side of the top of the processing box, a support frame symmetrically installed on the higher side of the top of the processing box and at the through slot along the width direction of the processing box, and a rotating shaft symmetrically arranged on the vertical surface of the processing box at the through slot along the height direction of the processing box, with the lower rotating shaft rotatably mounted on the inner wall of the processing box via bearings.

[0013] Preferably, the upper rotating shaft is located between the two support frames, and the two ends of the upper rotating shaft are mounted on the support frames on the corresponding sides by bearings. Pulleys are symmetrically installed on the rotating shaft along its length direction, and a transmission belt is installed between the upper and lower adjacent pulleys. Multiple conveying frames are evenly arranged on the transmission belt along its length direction.

[0014] Preferably, both transmission belts are provided with connecting blocks that cooperate with the conveying frame, and the conveying frame is installed between the corresponding two connecting blocks. A strainer is installed at the bottom of the conveying frame, and a dredging component that cooperates with the strainer is installed between the conveying frame and the processing box.

[0015] Preferably, the unblocking component includes an unblocking plate disposed at the bottom of the conveying frame and reciprocating along the height direction of the conveying frame. The unblocking plate is evenly provided with a plurality of unblocking protrusions that cooperate with the strainer. Both the conveying frame and the unblocking plate are provided with fixed protrusions. A telescopic spring rod is installed on the fixed protrusion corresponding to the conveying frame, and the telescopic end of the telescopic spring rod is installed on the fixed protrusion on the corresponding unblocking plate.

[0016] Preferably, fixed frames are symmetrically installed at both ends of the conveyor frame along its width direction. A reversing shaft is rotatably installed between the corresponding fixed frames via bearings. An adjusting block that moves up and down is slidably installed between the fixed frames on the side away from the corresponding conveyor frame. An adjusting rope is attached to the reversing shaft. One end of the adjusting rope is installed on the corresponding adjusting block, and the end of the adjusting rope away from the corresponding adjusting block is installed on the corresponding unblocking plate. A linkage frame is installed on the side of the adjusting block away from the adjusting rope. Rubber protrusions corresponding to the linkage frames are installed on the inner side wall of the processing box.

[0017] Preferably, the inside of the processing box is symmetrically provided with limiting rods that cooperate with the conveying frame near the filter frame along its width direction. The limiting rods are equipped with connecting protrusions, and a fixing frame is installed on the connecting protrusions. The fixing frame is installed on the inner wall of the processing box.

[0018] Preferably, the end of the limiting rod near the bottom of the processing box is provided with a guide protrusion to guide the conveyor frame.

[0019] Preferably, the cleaning assembly includes multiple reciprocating plates evenly distributed along the height direction of the filter frame. A cleaning brush is installed on the side of the reciprocating plate near the filter frame. A lifting rod is slidably arranged through the top of the treatment box along its height direction, and the reciprocating plate is installed on the lifting rod.

[0020] Preferably, a Z-shaped linkage rod is installed on the top of the lifting rod, and a telescopic elastic rod is installed on the higher side of the top of the processing box. The telescopic end of the telescopic elastic rod is installed on the long horizontal section of the linkage rod. The corresponding rotation shaft of the support frame passes through the corresponding support frame, and a rotation frame that cooperates with the short horizontal section of the linkage rod is installed on the circumferential surface of one end of the support frame through the rotation shaft.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The arc-shaped plate designed in this invention can effectively block the incoming flushing water and guide the water flow to change its trajectory, thereby forming a stable backflow. The backflow actively flushes the filter frame, and the reverse impact force of the water flow effectively removes the dirt attached to the surface of the filter frame. The removed dirt is promptly included in the working range of the conveying component and quickly discharged from the treatment box through the directional conveying function of the conveying component. This significantly improves the purification effect of the flushing water and ensures that the filter frame maintains good filtration performance.

[0023] 2. During the critical stage of the conveyor frame moving upward, the unblocking component designed in this invention will be activated simultaneously to actively unblock the leaking mesh, thereby promptly removing dirt and impurities that may clog the mesh openings. This effectively prevents water from being unable to flow smoothly due to mesh blockage, which could cause turbulence inside the conveyor frame and easily lead to the overflow of collected dirt with the water flow.

[0024] Furthermore, by ensuring the smooth flow of the filter, not only is the aforementioned problem of dirt overflow avoided, but more importantly, it ensures that the dirt accumulated inside the conveyor frame can be smoothly and completely transported to the outside of the treatment tank for centralized treatment along with the conveyor frame. This fundamentally avoids secondary pollution of the flushing water when dirt remains in the system or is discharged with the water flow, providing a reliable guarantee for maintaining the high quality of the flushing water recovery.

[0025] 3. The cleaning component designed in this invention can comprehensively cover all areas of the filter frame, reaching deep into the gaps and corners of the filter frame to thoroughly remove the dirt attached to it. At the same time, the cleaning component and the backflow of rinsing water form an efficient synergy. That is, when the cleaning component cleans the filter frame, the rinsing water will flow back in time. The water flow can wash away the dirt loosened during the cleaning process and carry it away from the surface of the filter frame. Through the dual action of cleaning and rinsing, the cleaning effect on the filter frame is significantly enhanced, further ensuring that the dirt on the filter frame can be completely removed, thereby ensuring that the filtration performance of the filter frame is not affected and maintaining the stable and efficient operation of the entire system.

[0037] The following is in conjunction with the appendix Figures 1 to 10 This application will be described in further detail.

[0038] This application discloses a PSA water ring vacuum pump mechanical seal flushing water recycling system, which can use the impact force of the flushing water backflow to remove dirt and then transport the removed dirt outward, avoiding the possibility of secondary pollution of the flushing water by the removed dirt.

[0039] Example 1:

[0040] Reference Figure 1 and Figure 2 A PSA water ring vacuum pump mechanical seal flushing water recycling system includes a hollow treatment tank 1, a drain pipe 2 installed through the top of the treatment tank 1, a protruding structure on the side wall of the treatment tank 1 away from the drain pipe 2, an inlet pipe 3 installed through the protruding structure, and an arc-shaped plate 4 and a filter mechanism 5 that cooperate with the arc-shaped plate 4 installed inside the treatment tank 1. The filter mechanism 5 includes:

[0041] The filter frame 51 is installed inside the treatment box 1 and located between the liquid inlet pipe 3 and the arc plate 4.

[0042] The conveying assembly 52 is installed inside the processing box 1 and located between the filter frame 51 and the inlet pipe 3, conveying the dirt filtered by the filter frame 51 to the outside.

[0043] The cleaning component 53 is installed inside the treatment box 1 and located between the drain pipe 2 and the filter frame 51 to clean the dirt on the filter frame 51.

[0044] The arc-shaped plate 4 can effectively block the incoming flushing water and guide the water flow to change its trajectory, thereby forming a stable backflow. The backflow then actively flushes the filter frame 51. With the help of the reverse impact force of the water flow, the dirt attached to the surface of the filter frame 51 is effectively removed. The removed dirt is promptly included in the working range of the conveying component 52 and quickly discharged from the treatment box 1 through the directional conveying function of the conveying component 52. This significantly improves the purification effect of the flushing water and ensures that the filter frame 51 maintains good filtration performance.

[0045] It should be noted that the protruding structure can restrict the flow of rinsing water into the treatment tank 1. That is, when the water flows through this structure, its flow cross-sectional area will be reduced accordingly.

[0046] According to the basic principles of fluid mechanics, under a constant flow rate, the flow velocity of water is inversely proportional to the flow cross-sectional area. Therefore, a decrease in the cross-sectional area will directly lead to a significant increase in the flow velocity of the flushing water. The flushing water with increased velocity can rush towards the arc-shaped plate 4 with greater impact force. When the high-speed flowing flushing water comes into contact with the arc-shaped plate 4, it will form a backflow due to the blocking effect of the arc-shaped plate 4.

[0047] Because the initial water flow velocity towards the arc-shaped plate 4 is relatively high, the resulting backflow also maintains a high velocity. This high-velocity backflow can act more powerfully on the filter frame 51, more thoroughly and effectively rinsing away impurities and other debris attached to the filter frame 51, thereby significantly improving the overall rinsing effect.

[0048] The filter frame 51 has a U-shaped structure, and a filter screen is installed on the inner wall of the filter frame 51. Since the filter screen is common knowledge, it is not shown in the figure for the sake of aesthetics in the subsequent drawing. In actual operation, flushing water is pumped into the treatment tank 1 through the liquid inlet pipe 3. After the flushing water fills the interior of the protruding structure of the treatment tank 1, it forms a water flow. At this time, the water flow flows towards the filter frame 51 at a certain speed. During the water flow, the filter frame 51 blocks the dirt inside the water flow, so that the dirt cannot pass through the filter frame 51. The water flow continues to move and rushes towards the arc plate 4.

[0049] After the water flow collides with the arc plate 4, a backflow is formed. The backflow of water uses its reverse impact force to help the dirt on the surface of the filter frame 51 to fall off smoothly. Then, the backflow of rinsing water is used to actively clean the filter frame 51.

[0050] Reference Figure 3 and Figure 4To avoid secondary pollution of the rinsing water by the detached dirt, the conveying assembly 52 provided by the present invention can convey the detached dirt to the outside of the treatment box 1. Specifically, the conveying assembly 52 includes a through groove opened on the higher side of the top of the treatment box 1. A support frame 521 is symmetrically installed on the higher side of the top of the treatment box 1 and at the through groove along the width direction of the treatment box 1. A rotating shaft 522 is symmetrically arranged on the vertical surface of the treatment box 1 at the height direction of the treatment box 1. The lower rotating shaft 522 is rotatably installed on the inner wall of the treatment box 1 through a bearing.

[0051] The upper rotating shaft 522 is located between the two support frames 521, and the two ends of the upper rotating shaft 522 are mounted on the support frames 521 on the corresponding sides through bearings. Pulleys 523 are symmetrically installed on the rotating shaft 522 along its length direction, and a transmission belt 524 is installed between the upper and lower adjacent pulleys 523. Multiple conveying frames 525 are evenly arranged on the transmission belt 524 along its length direction.

[0052] Both transmission belts 524 are provided with connecting blocks 526 that cooperate with the conveying frame 525, and the conveying frame 525 is installed between the corresponding two connecting blocks 526. A strainer 527 is installed at the bottom of the conveying frame 525, and a dredging component 54 that cooperates with the strainer 527 is installed between the conveying frame 525 and the processing box 1.

[0053] When the transmission belt 524 drives the conveyor frame 525 to move upward near the filter frame 51, the side of the conveyor frame 525 near the filter frame 51 has an opening to facilitate the entry of dirt into the conveyor frame 525. In specific operation, an existing drive motor (not shown in the figure) is installed on the outer wall of the treatment box 1. The output shaft of the drive motor is connected to any rotating shaft 522 through a coupling. The existing drive motor drives the corresponding rotating shaft 522 to rotate. During the rotation of the rotating shaft 522, the transmission belt 524 moves through the cooperation of another rotating shaft 522 and pulley 523. During the movement of the transmission belt 524, the conveyor frame 525 near the filter frame 51 moves upward through the connecting block 526. During the upward movement of the conveyor frame 525, the dirt that falls off due to backflow impact can be collected and processed.

[0054] When the conveyor frame 525 moves to the outside of the processing box 1 through the through groove, the staff quickly cleans the dirt at the bottom of the conveyor frame 525, and the cleaned conveyor frame 525 re-enters the processing box 1.

[0055] Reference Figures 4 to 6To prevent turbulence and potential leakage of dirt inside the conveying frame 525, the filter screen and conveying assembly 52 provided by this invention work together to ensure that the water inside the conveying frame 525 can always be discharged outwards. Specifically, the unblocking assembly 54 includes an unblocking plate 541 located at the bottom of the conveying frame 525 and reciprocating along the height of the conveying frame 525. The unblocking plate 541 has a plurality of unblocking protrusions 542 evenly distributed on it, which cooperate with the strainer 527. Both the conveying frame 525 and the unblocking plate 541 have fixing protrusions, and a telescopic spring rod 543 is installed on the corresponding fixing protrusion of the conveying frame 525 (see reference). Figure 3 The telescopic end of the telescopic spring rod 543 is installed on the fixed protrusion on the corresponding unblocking plate 541.

[0056] A fixed frame 544 is symmetrically installed at both ends of the conveying frame 525 along its width direction. A reversing shaft 545 is rotatably installed between the fixed frames 544 via bearings. An adjusting block 546 that moves up and down is slidably set between the fixed frames 544 on the side away from the corresponding conveying frame 525. An adjusting rope 547 is attached to the reversing shaft 545. One end of the adjusting rope 547 is installed on the corresponding adjusting block 546, and the other end of the adjusting rope 547 away from the corresponding adjusting block 546 is installed on the corresponding unblocking plate 541. A linkage frame 548 is installed on the side of the adjusting block 546 away from the adjusting rope 547. Rubber protrusions 549 corresponding to the linkage frame 548 are installed on the inner side wall of the processing box 1.

[0057] The rubber protrusion 549 and the linkage frame 548 move in parallel. In the initial state, the unblocking plate 541 and the strainer 527 are spaced a certain distance apart. During operation, as the conveyor frame 525 near the filter frame 51 moves upward, the linkage frame 548 it drives gradually comes into contact with the rubber protrusion 549. Because the rubber protrusion 549 has a certain elasticity and blocking ability, after the two come into contact, the rubber protrusion 549 will generate a downward resistance on the linkage frame 548. At this time, the conveying frame 525 continues to move upward, while the linkage frame 548 is blocked by the rubber protrusion 549 and cannot move upward synchronously with the conveying frame 525. As a result, the linkage frame 548 moves downward relative to the conveying frame 525. Then, the linkage frame 548 and the adjusting block 546 cooperate to drive the adjusting rope 547 to move on the reversing shaft 545. During the movement of the adjusting rope 547, the unblocking plate 541 moves upward until the unblocking plate 541 contacts the strainer 527. At this time, the telescopic spring rod 543 is in a compressed state.

[0058] As the drain plate 541 gradually approaches the mesh 527 under the action of mechanical transmission, the drain protrusions 542 distributed on its surface will first come into contact with the dirt attached to the mesh 527. As the distance between the two continues to decrease, the drain protrusions 542 will, with the help of their own structural shape, penetrate into the mesh and surface gaps of the mesh 527, and exert a squeezing, peeling and pushing effect on the dirt, thereby achieving the initial drain cleaning of the mesh 527.

[0059] After the drain plate 541 fully contacts the strainer 527, the conveyor frame 525 does not stop moving but continues to move upward. At this time, the linkage frame 548 connected to the conveyor frame 525 is subjected to a continuous upward traction force, which gradually exceeds the deformation limit of the rubber protrusion 549. Under the action of the traction force, the linkage frame 548 begins to overcome the elastic deformation resistance of the rubber protrusion 549, forcing the rubber protrusion 549 to undergo bending, compression, and other morphological changes. As the conveyor frame 525 continues to move upward, the linkage frame 548 continues to move upward until it completely passes over the rubber protrusion 549.

[0060] Once the linkage 548 passes the rubber protrusion 549, the external force on the rubber protrusion 549 disappears, and its own elasticity will cause it to gradually return to its initial shape, at which point it will no longer hinder the upward movement of the linkage 548. At the same time, the telescopic spring rod 543, which was originally in a compressed state, will quickly extend and reset after losing its external constraint. During the reset process, the telescopic spring rod 543 will drive the drain plate 541 to move away from the strainer 527 and reset.

[0061] This allows for the timely removal of dirt and impurities that may clog the mesh of the 527 strainer, effectively preventing water from flowing out smoothly due to mesh blockage and causing turbulence inside the conveyor frame 525, which could easily lead to the overflow of collected dirt with the water flow.

[0062] Furthermore, by ensuring that the mesh 527 is unobstructed, not only is the aforementioned problem of dirt overflow avoided, but more importantly, it ensures that the dirt accumulated inside the conveying frame 525 can be smoothly and completely transported to the outside of the treatment box 1 for centralized treatment along with the conveying frame 525. This fundamentally avoids secondary pollution of the flushing water when dirt remains in the system or is discharged with the water flow, providing a reliable guarantee for maintaining the high quality of the flushing water recovery.

[0063] Furthermore, by combining active conveying with rinsing the filter frame 51 through recirculation, the amount of dirt in the rinsing water is effectively reduced, ensuring the subsequent recycling of rinsing water.

[0064] Reference Figure 7 and Figure 8Due to the softness of the transmission belt 524 and the impact of the water flow, the conveyor frame 525 on the transmission belt 524 may shake when collecting dirt, resulting in a gap between the conveyor frame 525 and the filter frame 51, which may cause the dirt to not be completely collected. The present invention provides a limiting rod 11 to limit the conveyor frame 525. Specifically, the processing box 1 is symmetrically arranged inside its width direction with limiting rods 11 that cooperate with the conveyor frame 525 near the filter frame 51. The limiting rod 11 is equipped with a connecting protrusion, and a fixing frame 12 is installed on the connecting protrusion. The fixing frame 12 is installed on the inner wall of the processing box 1.

[0065] The end of the limiting rod 11 near the bottom of the processing box 1 is provided with a guide protrusion 13 to guide the conveying frame 525.

[0066] The distance from the limiting rod 11 to the filter frame 51 is equal to the width of the conveying frame 525. In actual operation, when the conveying frame 525 moves to one side of the filter frame 51, the limiting rod 11 can limit the conveying frame 525, so that the conveying frame 525 is always in close contact with the filter frame. This ensures that the conveying frame 525 will not shake when collecting dirt, reduces the impact of water flow on the stability of the conveying frame 525, and improves the dirt collection effect. The guide protrusion 13 can guide the conveying frame 525 when it moves to one side of the filter frame 51, avoiding the possibility that the water flow will impact the transmission belt 524 and cause the conveying frame 525 to not be fully aligned with the limiting rod 11.

[0067] When the flushing water inside the treatment tank 1 reaches a certain depth (that is, the flushing water passes over the arc plate 4 and flows into the treatment tank 1 and is located on one side of the drain pipe 2), the existing water pump (not shown in the figure) and the drain pipe 2 work together to discharge the treated flushing water inside the treatment tank 1 outward. It should be noted that the height of the flushing water inside the treatment tank 1 is always lower than the height of the through tank.

[0068] Example 2:

[0069] Reference Figure 9 and Figure 10 Based on Embodiment 1, the cleaning assembly 53 includes a plurality of reciprocating plates 531 evenly distributed along the height direction of the filter frame 51. A cleaning brush 532 is installed on the side of the reciprocating plate 531 near the filter frame 51. A lifting rod 533 is slidably arranged through the top of the treatment box 1 along its height direction, and the reciprocating plate 531 is installed on the lifting rod 533.

[0070] The top of the lifting rod 533 is equipped with a Z-shaped linkage rod 534. The top of the processing box 1 is equipped with a telescopic elastic rod 535. The telescopic end of the telescopic elastic rod 535 is installed on the long horizontal section of the linkage rod 534. The corresponding rotating shaft 522 of the support frame 521 passes through the corresponding support frame 521. The rotating shaft 522 passes through the circumferential surface of one end of the support frame 521 and is equipped with a rotating frame 536 that cooperates with the short horizontal section of the linkage rod 534.

[0071] The rotating frame 536 consists of an annular block mounted on the rotating shaft 522 and multiple circumferentially distributed swing frames on the annular block. During operation, when the rotating shaft 522 begins to rotate, it directly drives the connected rotating frame 536 to rotate synchronously. As the rotating frame 536 rotates, its circumferentially distributed swing frames gradually come into contact with the short horizontal section of the linkage rod 534. With the continuous rotation of the rotating frame 536, the swing frames exert a downward thrust on the short horizontal section of the linkage rod 534, thereby causing the entire linkage rod 534 to move downwards. During this process, the telescopic elastic rod 535 connected to the linkage rod 534 is simultaneously compressed and deformed, storing a certain amount of elastic potential energy.

[0072] As the linkage rod 534 moves downward, it transmits force to the reciprocating plate 531 via the lifting rod 533 connected to it, thereby causing the reciprocating plate 531 to move downward synchronously. The cleaning brush 532 installed on the reciprocating plate 531 will come into contact with the surface of the filter screen as the reciprocating plate 531 moves downward, and wipe away the dirt attached to the filter screen to achieve preliminary cleaning treatment.

[0073] The cleaning action of the cleaning brush 532 and the backflow impact of the rinsing water form an effective synergy. That is, the mechanical wiping of the brush can loosen the more stubborn dirt, while the backflow of rinsing water can wash away the loosened dirt in time. The interaction between the two further accelerates the speed at which dirt falls off the filter frame 51.

[0074] Furthermore, the reciprocating plate 531 does not simply move downwards in one direction, but rather moves up and down reciprocally under the elastic action of the telescopic elastic rod 535. During this reciprocating movement, the path and direction of the backflow of the flushing water are constantly changing, ensuring that the direction of the backflow is always dynamically changing. This results in the dirt on the filter frame 51 being constantly subjected to alternating forces with changing directions, preventing the dirt from adapting and remaining due to long-term exposure to forces in one direction. This further ensures the cleaning effect on the dirt on the filter frame 51, guaranteeing a more thorough cleaning of the filter frame 51.

[0075] The implementation principle of this invention is as follows:

[0076] (1) The water flows towards the filter frame 51 at a certain speed. During the water flow, the filter frame 51 blocks the dirt inside the water flow, so that the dirt cannot pass through the filter frame 51. The water flow continues to move and rushes towards the arc plate 4. After the water flow collides with the arc plate 4, a backflow is formed. The backflow water uses its reverse impact force to make the dirt on the surface of the filter frame 51 fall off smoothly. Then, the backflow of rinsing water is used to actively clean the filter frame 51.

[0077] (2) Any rotating shaft 522 rotates. During the rotation of the rotating shaft 522, the transmission belt 524 is moved by the cooperation of another rotating shaft 522 and pulley 523. During the movement of the transmission belt 524, the conveying frame 525 near the filter frame 51 is moved upward through the connecting block 526. During the upward movement of the conveying frame 525, the dirt that falls off due to backflow impact can be collected and treated.

[0078] (3) The linkage frame 548 and the adjusting block 546 work together to drive the adjusting rope 547 to move on the reversing shaft 545. During the movement of the adjusting rope 547, the unblocking plate 541 moves upward until the unblocking plate 541 contacts the strainer 527. At this time, the telescopic spring rod 543 is in a compressed state. When the unblocking plate 541 gradually approaches the strainer 527 under the action of mechanical transmission, the unblocking protrusions 542 distributed on its surface will first contact the dirt attached to the strainer 527. As the distance between the two continues to decrease, the unblocking protrusions 542 will use their own structural shape to penetrate into the mesh and surface gaps of the strainer 527, and exert a squeezing, peeling and pushing effect on the dirt, thereby achieving the initial unblocking treatment of the strainer 527.

[0079] (4) When the rinsing water inside the treatment tank 1 reaches a certain depth, the existing water pump and the drain pipe 2 are used to discharge the treated rinsing water inside the treatment tank 1 to the outside.
