Technical Field

[0001] The present invention relates to the technical field of drainage equipment for construction projects, and in particular to a water supply and drainage filtering device for construction projects and a method for using the same. Background Art

[0002] A construction project refers to an engineering entity formed through the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's needs for production, residence, study, public activities, etc. Construction projects are the planning, investigation, design, construction, completion, and other technical work and completed engineering entities for the construction, reconstruction, or expansion of buildings and ancillary structures and facilities, as well as modern building construction projects and the installation of supporting lines, pipelines, and equipment.

[0003] Among them, when the sewage generated in the construction project is discharged, the sewage often contains large solid impurities. When these solid impurities flow with the sewage, they will produce a large impact force. When the solid impurities come into contact with the filter, they will impact the surface of the filter, which can easily damage the filter. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a water supply and drainage filtering device for construction engineering, comprising a collecting mechanism, the collecting mechanism also comprising a filter box, the left and right sides of the filter box are both connected with water inlet pipes, and the inner wall of the filter box is rotatably connected with a fan-shaped frame;

[0005] The pushing mechanism comprises a pushing block slidably connected to the bottom of the inner wall of the filter box, a connecting rod 1 is contacted at the side wall of the fan-shaped frame, and a connecting rod 2 is rotatably connected at the inner wall of the connecting rod 1;

[0006] The blocking mechanism comprises a fixed frame fixedly connected to the inner wall of the filter box, a connecting pipe is connected through the bottom of the fixed frame, hydraulic oil is arranged on the inner wall of the connecting pipe, and a piston rod is slidably connected to the inner wall of the connecting pipe.

[0007] Preferably, the collecting mechanism further comprises a motor fixedly connected to the side wall of the filter box, the output end of the motor at the side wall is fixedly connected to the side wall of the fan-shaped frame, a filter screen is fixedly connected to the inner wall of the filter box, and an arc plate is fixedly connected to the bottom of the inner wall of the filter box;

[0008] Among them, six fixing frames are fixedly connected to the outer wall of the fan-shaped frame, and buckets are rotatably connected to the inner walls of the six fixing frames. Seven arc springs are fixedly connected to the side walls of the six buckets. The sewage generated in the construction project is discharged into the filter box through the water inlet pipe on the left, and then the motor is started to drive the fan-shaped frame to rotate. The fan-shaped frame will block the sewage entering the filter box, thereby blocking the solid impurities in the sewage. Through the rotation of the fan-shaped frame, the sewage can enter the right side of the filter box, filter the sewage through the filter screen, and then discharge the filtered sewage through the water inlet pipe on the right. At the same time, the solid impurities blocked by the fan-shaped frame will push the solid impurities at the bottom of the filter box to the arc surface of the arc plate as the fan-shaped frame rotates. At this time, since the fan-shaped frame rotates, it will also drive the bucket to rotate. When the bucket rotates to the arc surface of the arc plate, the solid impurities will be shoveled into the bucket.

[0009] Preferably, the collecting mechanism further comprises an inclined panel slidably connected to the inner wall of the filter box, two spring return rods are fixedly connected to the top of the inner wall of the filter box, the inner wall of the inclined panel is slidably connected to the outer wall of the spring return rod, and a discharge groove is provided on the side wall of the filter box;

[0010] Among them, a connecting plate is fixedly connected to the side wall of the inclined panel, and the outer wall of the connecting plate is slidably connected to the inner wall of the filter box. As the fan-shaped frame continues to rotate, the bucket will contact the inclined panel. At this time, the bucket is in an inclined state, and the solid impurities will be dumped on the inclined panel. At the same time, the bucket is rotated to squeeze the arc spring. As the bucket continues to rotate, the bucket will separate from the inclined panel, such as: Figure 5 As shown, the bucket returns to its original position through the rebound force of the arc spring 1.

[0011] The filter screen is then moved back and forth, and the filter screen is ...

[0012] Preferably, the pushing mechanism further comprises a sliding frame slidably connected to the side wall of the pushing block, the side wall of the sliding frame is rotatably connected to the outer wall of the second connecting rod, a placement groove is provided on the inner wall of the filter box, and a concave-convex plate is fixedly connected to the inner wall of the placement groove;

[0013] Among them, a return spring is fixedly connected to the side wall of the pushing block, and the side wall of the pushing block is slidably connected to the side wall of the concave-convex plate. The force of the connecting rod moving will drive the connecting rod one to rotate when the connecting rod rotates, so that the connecting rod one rotates around the center of the fan-shaped frame, and the connecting rod two is pulled to move back and forth, driving the sliding frame to move, and the pushing block is pulled to move by the sliding frame. When the pushing block moves toward the fan-shaped frame, it will move from the recessed position of the concave-convex plate to the raised position, allowing the pushing block to move laterally to squeeze the return spring. When the pushing block moves to the recessed position of the concave-convex plate again, the rebound force of the return spring will be released to push the pushing block back to its position. This reciprocating process will cause the pushing block to rub the bottom of the filter box to prevent solid impurities from adhering to the bottom of the filter box.

[0014] Preferably, the blocking mechanism further comprises a piston rod 2 slidably connected to the inner wall of the connecting pipe, a spring plate slidably connected to the inner wall of the fixed frame, a connecting frame fixedly connected to the side wall of the push block, and seven nozzles fixedly connected to the top of the fixed frame;

[0015] Among them, two fixed rods are fixedly connected to the top of the spring plate, and arc rods are fixedly connected to the outer walls of the two fixed rods. By utilizing the force of the moving push block, when the push block moves back and forth and away from the fan-shaped frame, the push block drives the connecting frame to move. When the connecting frame contacts the piston rod, it will push the piston rod to move, squeezing the hydraulic oil in the connecting pipe, and the hydraulic oil will push the piston rod to move, lifting the spring plate and allowing the spring plate to accumulate rebound force. At the same time, it pushes the sewage in the fixed frame and sprays it out through the nozzle to form a barrier, which pre-blocks the solid impurities in the sewage and reduces the impact force of the solid impurities in the sewage.

[0016] Preferably, the blocking mechanism further comprises a fixed plate fixedly connected to the inner wall of the filter box, a swing plate 1 is rotatably connected to the inner wall of the filter box, a swing plate 2 is rotatably connected to the outer wall of the swing plate 1, and five arc springs 2 are fixedly connected to the left and right sides of the fixed plate;

[0017] Among them, the bottom of the arc spring two on the left side is fixedly connected to the top of the swing plate one, and the bottom of the arc spring two on the right side is fixedly connected to the top of the swing plate two. Using the force of the spring plate moving, when the pushing block moves toward the fan-shaped frame, the spring plate will drop, driving the fixed rod to drop, and letting the arc rod drop. At this time, the driving force on the swing plate one and the swing plate two disappears. Since the arc spring two was in a compressed state before, the rebound force of the arc spring two will be released, pushing the swing plate two and the swing plate one to rotate, so that the swing plate two and the swing plate one push the sewage on the top of the inner wall of the filter box to flow.

[0018] A method for using a water supply and drainage filtering device for a construction project comprises the following steps:

[0019] S1: solid impurity barrier;

[0020] S2: solid impurity collection;

[0021] S3: Solid impurities are discharged.

[0022] The present invention has the following beneficial effects:

[0023] (1) When the present invention is used, the sewage generated in the construction project is discharged into the filter box through the water inlet pipe on the left side, and then the motor is started to drive the fan-shaped frame to rotate. The fan-shaped frame will block the sewage entering the filter box, thereby blocking the solid impurities in the sewage. Through the rotation of the fan-shaped frame, the sewage can enter the right side of the filter box, filter the sewage through the filter screen, and then discharge the filtered sewage through the water inlet pipe on the right side. At the same time, the solid impurities blocked by the fan-shaped frame will push the solid impurities at the bottom of the filter box onto the curved surface of the arc plate as the fan-shaped frame rotates. At this time, since the rotation of the fan-shaped frame will also drive the bucket to rotate, when the bucket rotates to the curved surface of the arc plate, the solid impurities will be shoveled into the bucket. As the fan-shaped frame continues to rotate, the bucket will contact the inclined plate. At this time, the bucket is in an inclined state, and the solid impurities will be dumped on the inclined plate. At the same time, the bucket is rotated to squeeze the arc spring 1. As the bucket continues to rotate, the bucket will separate from the inclined plate, such as: Figure 5 As shown, the bucket is returned to its position by the rebound force of the arc spring 1. When the fan-shaped frame rotates, the pushing frame can also be driven to rotate through the connecting rod. When the bucket is separated from the filter screen, the pushing frame will contact the connecting plate, lift the connecting plate, drive the inclined plate to rise, and allow the spring return rod to accumulate rebound force. As the pushing frame rotates, the pushing frame will be separated from the connecting plate. At this time, the rebound force of the spring return rod will be released, causing the inclined plate to shake, which can move the solid impurities toward the discharge trough. Since the sewage is continuously discharged, it is difficult for the sewage to enter the top of the inclined plate, ensuring that the solid impurities can be discharged smoothly until the solid impurities fall into the collection box, and the larger solid impurities are collected to prevent the solid impurities from impacting the filter screen and causing damage to the surface of the filter screen, thereby reducing the damage to the filter screen and maintaining the integrity of the filter screen.

[0024] (2) The present invention utilizes the force of the connecting rod to move. When the connecting rod rotates, it also drives the connecting rod 1 to rotate, so that the connecting rod 1 rotates around the center of the fan-shaped frame, pulls the connecting rod 2 to move back and forth, drives the sliding frame to move, and pulls the push block to move through the sliding frame. When the push block moves toward the fan-shaped frame, it moves from the concave position of the concave-convex plate to the convex position, allowing the push block to move laterally and squeeze the reset spring. When the push block moves to the concave position of the concave-convex plate again, the rebound force of the reset spring will be released, pushing the push block back to its original position. This reciprocating process will cause the push block to contact the filter. The bottom of the box is rubbed to prevent solid impurities from adhering to the bottom of the filter box. At the same time, it can also push the solid impurities on the left side of the filter box toward the fan-shaped frame. The blades of the fan-shaped frame will drive the water flow to produce a vortex flow during the rotation. Due to the rotation of the water flow, this vortex flow will cause the surrounding impurities to gather to the bottom of the fan-shaped frame. The impurities are collected through the bucket to prevent some solid impurities from contacting the fan-shaped frame. The solid impurities may splash away from the fan-shaped frame and adhere to the bottom of the filter box, causing impurities to accumulate on the left side of the filter box, affecting the flow of sewage.

[0025] (3) The present invention utilizes the force of the push block to move. When the push block moves back and forth and away from the fan-shaped frame, the push block drives the connecting frame to move. When the connecting frame contacts the piston rod one, it will push the piston rod one to move, squeezing the hydraulic oil in the connecting pipe. The hydraulic oil will push the piston rod two to move, lift the spring plate, and allow the spring plate to accumulate rebound force. At the same time, it pushes the sewage in the fixed frame to be sprayed out through the nozzle to form a barrier, pre-blocking the solid impurities in the sewage and reducing the impact force of the solid impurities in the sewage. When the push block approaches the fan-shaped frame again, the connecting frame is separated from the piston rod one. The spring plate rebounds rapidly under the action of the accumulated rebound force, pushing the piston rod two back to its original position and sucking back the hydraulic oil in the connecting pipe to prepare for the next push. At this time, the sewage in the fixed frame is also sucked back, and the nozzle stops spraying water. Through this reciprocating motion, the push block continuously pushes the connecting frame, causing the spring plate to repeatedly accumulate and release rebound force, thereby continuously producing a barrier effect, allowing some solid impurities to be buffered. Through two blockings, the solid impurities can be fully intercepted.

[0026] (4) The present invention utilizes the force of the spring plate to move. When the push block moves toward the fan-shaped frame, the spring plate will drop, driving the fixed rod to drop, and causing the arc rod to drop. At this time, the driving force on the swing plate 1 and the swing plate 2 disappears. Since the arc spring 2 was previously in a compressed state, the rebound force of the arc spring 2 will be released, pushing the swing plate 2 and the swing plate 1 to rotate, so that the swing plate 2 and the swing plate 1 push the sewage on the top of the inner wall of the filter box to flow, thereby avoiding that when the fan-shaped frame rotates, its blades push the water flow, which may increase or decrease the local speed of the water flow. This change may cause uneven distribution of the water flow, which may cause the water flow in certain areas on the top of the filter box to stagnate, causing impurities to quickly gather together, increasing the difficulty of cleaning the subsequent impurities.

[0041] For example, see Figure 1 - Figure 5 The present invention is a water supply and drainage filtering device for construction engineering, comprising a collecting mechanism 1, the collecting mechanism 1 also comprising a filter box 101, the left and right sides of the filter box 101 are connected with a water inlet pipe 102, and the inner wall of the filter box 101 is rotatably connected with a fan-shaped frame 103;

[0042] The pushing mechanism 2 includes a pushing block 201 slidably connected to the bottom of the inner wall of the filter box 101, a connecting rod 1 202 is contacted at the side wall of the fan-shaped frame 103, and a connecting rod 203 is rotatably connected to the inner wall of the connecting rod 1 202;

[0043] The blocking mechanism 3 includes a fixed frame 301 fixedly connected to the inner wall of the filter box 101, a connecting pipe 302 is connected to the bottom of the fixed frame 301, hydraulic oil is provided on the inner wall of the connecting pipe 302, and a piston rod 303 is slidably connected to the inner wall of the connecting pipe 302.

[0044] The collecting mechanism 1 also includes a motor 104 fixedly connected to the side wall of the filter box 101, the output end of the motor 104 at the side wall is fixedly connected to the side wall of the fan-shaped frame 103, a filter screen 105 is fixedly connected to the inner wall of the filter box 101, and an arc plate 106 is fixedly connected to the bottom of the inner wall of the filter box 101;

[0045] Among them, six fixing frames 107 are fixedly connected to the outer wall of the fan-shaped frame 103, and buckets 108 are rotatably connected to the inner walls of the six fixing frames 107. Seven arc springs 109 are fixedly connected to the side walls of the six buckets 108. The sewage generated in the construction project is discharged into the filter box 101 through the water inlet pipe 102 on the left, and then the motor 104 is started to drive the fan-shaped frame 103 to rotate. The fan-shaped frame 103 will block the sewage entering the filter box 101, thereby blocking the solid impurities in the sewage. , the sewage can enter the right side of the filter box 101, filter the sewage through the filter screen 105, and then discharge the filtered sewage through the water inlet pipe 102 on the right. At the same time, the solid impurities blocked by the fan-shaped frame 103 will push the solid impurities at the bottom of the filter box 101 to the curved surface of the curved plate 106 as the fan-shaped frame 103 rotates. At this time, since the fan-shaped frame 103 rotates, it will also drive the bucket 108 to rotate. When the bucket 108 rotates to the curved surface of the curved plate 106, the solid impurities will be shoveled into the bucket 108.

[0046] The collecting mechanism 1 further comprises an inclined plate 110 slidably connected to the inner wall of the filter box 101, two spring return rods 111 are fixedly connected to the top of the inner wall of the filter box 101, the inner wall of the inclined plate 110 is slidably connected to the outer wall of the spring return rod 111, and a discharge groove 112 is provided on the side wall of the filter box 101;

[0047] Among them, the side wall of the inclined panel 110 is fixedly connected with a connecting plate 113, and the outer wall of the connecting plate 113 is slidably connected to the inner wall of the filter box 101. As the fan-shaped frame 103 continues to rotate, the bucket 108 will contact the inclined panel 110. At this time, the bucket 108 is in an inclined state, and solid impurities will be dumped on the inclined panel 110. At the same time, the bucket 108 is rotated to squeeze the arc spring 109. As the bucket 108 continues to rotate, the bucket 108 will be separated from the inclined panel 110, such as: Figure 5 As shown, the bucket 108 is returned to its original position by the rebound force of the arc spring 109.

[0048] The collecting mechanism 1 also includes a pushing frame 114 rotatably connected to the inner wall of the filter box 101, a connecting rod 115 is fixedly connected to the side wall of the fan-shaped frame 103, the side wall of the connecting rod 115 is fixedly connected to the side wall of the pushing frame 114, the outer wall of the connecting rod 115 is rotatably connected to the inner wall of the connecting rod 202, and a collecting box 116 is slidably connected to the side wall of the filter box 101. When the fan-shaped frame 103 rotates, the pushing frame 114 can also be driven to rotate by the connecting rod 115. When the bucket 108 is separated from the filter screen 105, the pushing frame 114 will contact with the connecting plate 113, lift the connecting plate 113, drive the inclined plate 110 to rise, and let the spring return to normal state. The positioning rod 111 accumulates resilience, and as the pushing frame 114 rotates, the pushing frame 114 will be separated from the connecting plate 113. At this time, the resilience of the spring return rod 111 will be released, causing the inclined plate 110 to shake, so that the solid impurities can move toward the discharge groove 112. Since the sewage is continuously discharged, it is difficult for the sewage to enter the top of the inclined plate 110, ensuring that the solid impurities can be discharged smoothly until the solid impurities fall into the collection box 116, and the larger solid impurities are collected to prevent the solid impurities from impacting the filter screen 105 and causing damage to the surface of the filter screen 105, thereby reducing the damage to the filter screen 105 and maintaining the integrity of the filter screen 105.

[0049] For example 2, please refer to Figure 5 - Fig.10 The present invention is a water supply and drainage filtering device for construction engineering. On the basis of the first embodiment, the pushing mechanism 2 further comprises a sliding frame 204 slidably connected to the side wall of the pushing block 201, the side wall of the sliding frame 204 is rotatably connected to the outer wall of the second connecting rod 203, a placement groove 206 is provided on the inner wall of the filter box 101, and a concave-convex plate 205 is fixedly connected to the inner wall of the placement groove 206;

[0050] The side wall of the push block 201 is fixedly connected with a return spring 207, and the side wall of the push block 201 is slidably connected with the side wall of the concave-convex plate 205. The force of the connecting rod 115 moving will also drive the connecting rod 1 202 to rotate when the connecting rod 115 rotates, so that the connecting rod 1 202 rotates around the center of the fan-shaped frame 103, pulling the connecting rod 203 to move back and forth, driving the sliding frame 204 to move, and pulling the push block 201 to move through the sliding frame 204. When the push block 20 When the push block 201 moves toward the fan-shaped frame 103, it moves from the concave position of the concave-convex plate 205 to the convex position, so that the push block 201 moves horizontally to squeeze the return spring 207. When the push block 201 moves to the concave position of the concave-convex plate 205 again, the resilience of the return spring 207 is released to push the push block 201 back to its original position. In this way, the push block 201 rubs the bottom of the filter box 101 to prevent solid impurities from adhering to the bottom of the filter box 101.

[0051] The blocking mechanism 3 also includes a piston rod 304 slidably connected to the inner wall of the connecting pipe 302, a spring plate 306 slidably connected to the inner wall of the fixed frame 301, a connecting frame 305 fixedly connected to the side wall of the push block 201, and seven nozzles 307 fixedly connected to the top of the fixed frame 301;

[0052] Among them, two fixing rods 308 are fixedly connected to the top of the spring plate 306, and the outer walls of the two fixing rods 308 are fixedly connected with arc rods 309. By utilizing the force of the movement of the pushing block 201, when the pushing block 201 moves back and forth and away from the fan-shaped frame 103, the pushing block 201 drives the connecting frame 305 to move. When the connecting frame 305 contacts the piston rod 1 303, it will push the piston rod 1 303 to move, squeezing the hydraulic oil in the connecting pipe 302, and the hydraulic oil will push the piston rod 2 304 to move, lift the spring plate 306, and allow the spring plate 306 to accumulate resilience. At the same time, it pushes the sewage in the fixed frame 301 to be sprayed out through the nozzle 307 to form a barrier, pre-block the solid impurities in the sewage, and reduce the impact force of the solid impurities in the sewage.

[0053] The blocking mechanism 3 also includes a fixed plate 310 fixedly connected to the inner wall of the filter box 101, a swing plate 1 311 is rotatably connected to the inner wall of the filter box 101, a swing plate 2 312 is rotatably connected to the outer wall of the swing plate 1 311, and five arc springs 2 313 are fixedly connected to the left and right sides of the fixed plate 310;

[0054] Among them, the bottom of the arc spring 2 313 on the left side is fixedly connected to the top of the swing plate 1 311, and the bottom of the arc spring 2 313 on the right side is fixedly connected to the top of the swing plate 2 312. Using the force of the spring plate 306 moving, when the pushing block 201 moves toward the fan-shaped frame 103, the spring plate 306 will descend, driving the fixed rod 308 to descend, and allowing the arc rod 309 to descend. At this time, the driving force on the swing plate 1 311 and the swing plate 2 312 disappears. Since the arc spring 2 313 was in a compressed state before, the rebound force of the arc spring 2 313 will be released, pushing the swing plate 2 312 and the swing plate 1 311 to rotate, so that the swing plate 2 312 and the swing plate 1 311 push the sewage on the top of the inner wall of the filter box 101 to flow.

[0055] There is no limitation on the number of the above components, and relevant technicians in the field can freely set them according to actual needs, as long as the above components are installed at the connection positions of the corresponding components.

[0056] The method for using the water supply and drainage filtering device for the construction project includes the following steps:

[0057] S1: solid impurity barrier;

[0058] S2: solid impurity collection;

[0059] S3: Solid impurities are discharged.

[0060] A specific application of this embodiment is: when the present invention is used, the sewage generated in the construction project is discharged into the filter box 101 through the water inlet pipe 102 on the left, and then the motor 104 is started to drive the fan-shaped frame 103 to rotate. The fan-shaped frame 103 will block the sewage entering the filter box 101, thereby blocking the solid impurities in the sewage. Through the rotation of the fan-shaped frame 103, the sewage can enter the right side of the filter box 101, and the sewage is filtered through the filter screen 105. Then, the filtered sewage is discharged through the water inlet pipe 102 on the right. At the same time, the solid impurities blocked by the fan-shaped frame 103 will be removed as the fan-shaped frame 103 rotates. The solid impurities at the bottom of the filter box 101 are pushed onto the curved surface of the curved plate 106. At this time, since the fan-shaped frame 103 rotates, it will also drive the bucket 108 to rotate. When the bucket 108 rotates to the curved surface of the curved plate 106, the solid impurities will be shoveled into the bucket 108. As the fan-shaped frame 103 continues to rotate, the bucket 108 will contact the inclined plate 110. At this time, the bucket 108 is in an inclined state, and the solid impurities will be dumped onto the inclined plate 110. At the same time, the bucket 108 is rotated to squeeze the arc spring 109. As the bucket 108 continues to rotate, the bucket 108 will separate from the inclined plate 110, such as: Figure 5 As shown, the bucket 108 is returned to its original position by the rebound force of the arc spring 109. When the fan-shaped frame 103 rotates, the push frame 114 can also be driven to rotate through the connecting rod 115. When the bucket 108 is separated from the filter screen 105, the push frame 114 will contact the connecting plate 113, lift the connecting plate 113, and drive the inclined plate 110 to rise, so that the spring return rod 111 accumulates the rebound force. As the push frame 114 rotates, the push frame 114 will be separated from the connecting plate 113. At this time, the spring return rod The rebound force of 111 will be released, causing the inclined panel 110 to shake, so that the solid impurities can move toward the discharge groove 112. Since the sewage is continuously discharged, it is difficult for the sewage to enter the top of the inclined panel 110, ensuring that the solid impurities can be discharged smoothly until the solid impurities fall into the collection box 116, and the larger solid impurities are collected to prevent the solid impurities from impacting the filter screen 105, causing damage to the surface of the filter screen 105, thereby reducing the damage to the filter screen 105 and maintaining the integrity of the filter screen 105;

[0061] Secondly, when the connecting rod 115 rotates, it will also drive the connecting rod 1 202 to rotate, so that the connecting rod 1 202 rotates around the center of the fan-shaped frame 103, pulling the connecting rod 203 to move back and forth, driving the sliding frame 204 to move, and pulling the pushing block 201 to move through the sliding frame 204. When the pushing block 201 moves toward the fan-shaped frame 103, it will move from the recessed position of the concave-convex plate 205 to the raised position, allowing the pushing block 201 to move laterally and squeeze the reset spring 207. When the pushing block 201 moves to the recessed position of the concave-convex plate 205 again, the resilience of the reset spring 207 will be released, pushing the pushing block 201 back to its original position, and so on and so forth, 1. The bottom of the filter box 101 is rubbed to prevent solid impurities from adhering to the bottom of the filter box 101. At the same time, the solid impurities on the left side of the filter box 101 can be pushed to move toward the fan-shaped frame 103. The blades of the fan-shaped frame 103 will drive the water flow to generate a vortex flow during the rotation process. Due to the rotation of the water flow, this vortex flow will cause the surrounding impurities to gather at the bottom of the fan-shaped frame 103. The bucket 108 is used to collect the impurities to prevent some solid impurities from contacting the fan-shaped frame 103. The solid impurities may splash away from the fan-shaped frame 103 and adhere to the bottom of the filter box 101, causing the impurities to accumulate on the left side of the filter box 101, affecting the flow of sewage.

[0062] Secondly, when the push block 201 moves back and forth and moves away from the fan-shaped frame 103, the push block 201 drives the connecting frame 305 to move. When the connecting frame 305 contacts the piston rod 1 303, it will push the piston rod 1 303 to move, squeeze the hydraulic oil in the connecting pipe 302, and the hydraulic oil will push the piston rod 2 304 to move, lift the spring plate 306, and let the spring plate 306 accumulate resilience. At the same time, it pushes the sewage in the fixed frame 301 to be sprayed out through the nozzle 307 to form a barrier, pre-blocking the solid impurities in the sewage and reducing the impact of the solid impurities in the sewage. When the push block 201 approaches again When the fan-shaped frame 103 is moved, the connecting frame 305 is separated from the piston rod 1 303, and the spring plate 306 rebounds rapidly under the action of the accumulated resilience, pushing the piston rod 2 304 back to its original position, and at the same time sucking back the hydraulic oil in the connecting pipe 302, preparing for the next push. At this time, the sewage in the fixed frame 301 is also sucked back, and the nozzle 307 stops spraying water. Through this reciprocating motion, the pushing block 201 continuously pushes the connecting frame 305, so that the spring plate 306 repeatedly accumulates and releases the resilience, thereby continuously generating a barrier effect, allowing some solid impurities to be buffered. Through two blockings, the solid impurities can be fully intercepted;

[0063] Secondly, when the pushing block 201 moves toward the fan-shaped frame 103, the spring plate 306 will descend, driving the fixed rod 308 to descend, allowing the arc rod 309 to descend. At this time, the driving force on the swing plate 1 311 and the swing plate 2 312 disappears. Since the arc spring 2 313 was in a compressed state before, the resilience of the arc spring 2 313 will be released, pushing the swing plate 2 312 and the swing plate 1 311 to rotate, so that the swing plate 2 312 and the swing plate 1 311 push the sewage on the top of the inner wall of the filter box 101 to flow, avoiding that when the fan-shaped frame 103 rotates, its blades push the water flow, which may increase or decrease the local speed of the water flow. This change may cause uneven distribution of the water flow, which may cause the water flow in some areas on the top of the filter box 101 to stagnate, causing impurities to gather quickly, increasing the difficulty of cleaning subsequent impurities.
