Description

Technical Field

[0001] This invention relates to the technical field of wastewater treatment, and specifically to a water purification device for wastewater treatment. Background Technology

[0002] Wastewater treatment and purification equipment integrates physical, chemical, or biological technologies to achieve wastewater purification and resource recovery. Its treatment steps include pretreatment, biological treatment, and advanced treatment. Chemicals are added during treatment, and sediment or floating matter will be generated during the process, which needs to be cleaned up promptly to avoid affecting subsequent treatment.

[0003] The patent document with announcement number CN117049672B discloses a wastewater treatment agent addition and mixing device for wastewater treatment. The device is characterized by including a positioning component and an inlet pipe. The inlet of the positioning component corresponds to the feeding component. The feeding component has two sets of feeding troughs. The left side of the feeding trough is directly connected to the sedimentation tank. The end of the feeding component is connected in series with the two sets of sedimentation tanks. A collection component is rotatably installed on the sedimentation tank. A discharge component is provided at the outlet of the sedimentation tank. The discharge column of the collection component is located in the middle of the sedimentation tank. The discharge column is hollow and has a rotating frame rotatably mounted on the top. An extension rod is mounted on the rotating frame, and a support frame is mounted at the end of the extension rod. The support frame contacts the edge of the sedimentation tank. A collection belt is installed at the bottom of the extension rod, and the outer wall of the collection belt has raised strips. First, the rotating frame is rotatably mounted on the top of the discharge column. The extension rod and the support frame can slowly rotate on the sedimentation tank. At this time, the extension rod will collect the debris on the surface of the sewage. The collection belt is installed at the lower end of the extension rod. After operation, the collection belt can drive the debris out, allowing the debris to be collected towards the discharge column, thus discharging the debris from the surface of the sewage.

[0004] However, this solution also has the following problems: while the collection belt collects floating debris into the discharge column during operation, the floating debris causes a large amount of water to be carried into the collection chamber during collection, requiring secondary filtration and making the process cumbersome. Furthermore, this method can only treat impurities floating on the surface; during the process, some impurities will settle to the bottom of the sedimentation tank, making collection difficult. Summary of the Invention

[0005] This invention provides a water purification device for wastewater treatment, which aims to solve the problem in related technologies where impurities contain a large amount of water and it is difficult to collect precipitated impurities.

[0006] The wastewater treatment purification device of the present invention includes a mounting frame rotatably installed in a sedimentation tank. The mounting frame is provided with a filter frame, a drive assembly, a squeezing assembly, and a collection assembly. The filter frame is slidably mounted on the mounting frame. An interception part is horizontally arranged at the bottom of the filter frame. The squeezing assembly is arranged above the interception part and above the wastewater. The collection assembly is located on one side of the squeezing assembly. The drive assembly is connected to the filter frame to drive the filter frame and the interception part to move up and down. The up and down movement of the interception part disturbs the impurities at the bottom of the sedimentation tank, causing them to float in the water. The filter frame rotates with the mounting frame to collect the floating impurities. Then the interception part moves upward to cooperate with the squeezing assembly to squeeze out the water in the impurities. Subsequently, the collection assembly collects the impurities.

[0007] The effect is that by setting an interception section at the bottom of the filter frame and setting a drive component to move the filter frame up and down, the impurities at the bottom of the sedimentation tank are disturbed, causing the impurities at the bottom to float in the sedimentation tank. These impurities are then collected as the filter frame rotates with the mounting frame. Specifically, the rotation of the mounting frame causes the filter frame to rotate around the center of the sedimentation tank, while the drive component moves the filter frame up and down, simultaneously moving the interception section up and down. During this process, impurities at the bottom of the sedimentation tank float and briefly detach from the bottom. Meanwhile, the filter frame moves in a circular motion within the sedimentation tank, collecting these impurities. After the interception section moves above the water surface, it can cooperate with a squeezing component to squeeze the impurities, expelling the water within them before collection. This avoids secondary filtration and improves the efficiency of impurity collection.

[0008] Preferably, the extrusion assembly includes: an elastic telescopic plate connected to the mounting bracket, and an extrusion plate located below the elastic telescopic plate, the extrusion plate being located above the interception section and parallel to the interception section.

[0009] The interceptor can move upwards to move out of the water and gradually approach the squeezing plate. The squeezing plate is set parallel to the interceptor so that the interceptor can fully squeeze the impurities when it approaches the squeezing plate and discharge the water from the impurities.

[0010] Preferably, the collection assembly includes: a pusher, a scraper, and a collection frame mounted on a mounting frame. The collection frame has an upward-facing opening. An elastic telescopic plate is slidably fitted with the mounting frame. The output end of the pusher is connected to the elastic telescopic plate to drive the elastic telescopic plate to move left and right. The scraper includes a horizontal part and a vertical part. The horizontal part is connected to the extrusion plate, and the vertical part is located between the extrusion plate and the filter frame. After the interception part extrudes impurities, the interception part abuts against the lower end of the vertical part, and the upper surface of the interception part is flush with the opening of the collection frame. The pusher drives the scraper to move above the collection frame through the elastic telescopic plate and the extrusion plate. The vertical part pushes the impurities on the interception part into the collection frame.

[0011] After the impurities are squeezed out, the upper surface of the interceptor is flush with the opening end of the collection frame. Then, the pusher moves the elastic telescopic plate toward the collection frame. At the same time, the elastic telescopic plate moves the horizontal and vertical parts. As the vertical part moves, it scrapes off the impurities on the interceptor and moves the impurities to the collection frame. When the squeezing plate moves to the opening of the collection frame, the impurities enter the collection frame so that they can be collected through the collection frame.

[0012] Preferably, a slide rod connected to the horizontal part is provided above the extrusion plate, the horizontal part is slidably sleeved on the outside of the slide rod, and a spring is provided between the horizontal part and the extrusion plate to connect the two.

[0013] A spring is provided between the horizontal part and the extrusion plate, so that the horizontal part and the extrusion plate are elastically connected. That is, the horizontal part can move relative to the extrusion plate, so that when the intercepting part extrudes impurities, the vertical part is always in contact with the intercepting part, so that the impurities on the intercepting part are scraped off when the vertical part moves.

[0014] Preferably, a drain pipe is coaxially arranged below the mounting frame, and an intermediate frame communicating with the interior of the drain pipe is provided at the upper end of the drain pipe. An opening is provided at the upper end of the intermediate frame, and the end of the collection frame extends horizontally to the top of the intermediate frame. A drain port is provided at the bottom of the collection frame, which is located above the intermediate frame. A spiral conveyor plate is rotatably assembled inside the collection frame, and the spiral conveyor plate rotates to push the impurities in the collection frame to the drain port.

[0015] After impurities enter the collection frame, the spiral conveyor rotates, causing the impurities to move within the collection frame and push them to the drain outlet. Subsequently, the impurities enter the drain pipe through the drain outlet and the intermediate frame, thus achieving the collection of impurities for subsequent centralized treatment.

[0016] Preferably, the drive assembly includes: a second drive component located at the bottom of the mounting frame, a drive screw connected to the output end of the second drive component, and a first drive sleeve. The drive screw is rotatably mounted on the mounting frame and is arranged in a vertical direction. The first drive sleeve is mounted on the filter frame, and the drive screw and the first drive sleeve are threaded together. The drive screw rotates in both directions to drive the filter frame to move up and down.

[0017] The second driving component drives the driving screw to rotate. The rotation of the driving screw drives the filter frame to move vertically through the first driving sleeve. At the same time, the second driving component drives the driving screw to rotate back and forth in both directions, thereby driving the filter frame to move back and forth in the vertical direction to adjust the position of the filter frame.

[0018] Preferably, the mounting frame is equipped with a spray pipe, which is slidably mounted on the mounting frame. The drive assembly is connected to the spray pipe to drive the spray pipe to move up and down. The spray pipe and the filter frame are respectively located on both sides of the mounting frame.

[0019] The drive component moves the filter frame and the spray pipe up and down simultaneously, spraying chemicals into the wastewater. By moving the spray pipe up and down, the chemicals are sprayed more thoroughly into the wastewater, improving the wastewater treatment efficiency.

[0020] Preferably, there are two sets of drive screws, and a second drive sleeve is installed on the spraying pipe. The drive screws and the second drive sleeve are threaded together. The threads of the two sets of drive screws are opposite. A transmission belt is provided at the output end of the second drive component. The transmission belt is simultaneously sleeved on the outside of the two sets of drive screws to drive the two drive screws to rotate synchronously in the same direction.

[0021] The drive unit drives two sets of drive screws to rotate simultaneously via a transmission belt. The drive screws drive the filter frame to move via drive sleeve one and drive the spray pipe to move via drive sleeve two, thereby simultaneously adjusting the positions of the filter frame and the spray pipe.

[0022] Preferably, both the spray pipe and the filter frame are provided in two sets, with the interception part located on the side of the filter frame closer to the rotation direction of the mounting frame.

[0023] Preferably, multiple slide bars are evenly arranged on the extrusion plate, and a clearance groove is provided on the horizontal part, which is sleeved on the outside of the elastic telescopic plate through the clearance groove.

[0024] By setting a clearance groove on the horizontal part, the horizontal part can slide outside the elastic telescopic plate, reducing the interference between the elastic telescopic plate and the horizontal part.

[0025] Beneficial effects:

[0026] The present invention features a filter screen that slides up and down on a mounting frame, and an interception part at the bottom of the filter screen that can agitate impurities at the bottom of the sedimentation tank and make them float. In addition, after the interception part is removed from the sewage, it can cooperate with a squeezing plate to discharge excess water from the impurities, and finally collect them, thereby improving the collection efficiency of impurities in sewage and the water content of the collected impurities.

[0037] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] like Figures 1 to 8 As shown, the wastewater treatment purification equipment of the present invention includes a sedimentation tank 1 and a mounting frame 2 disposed within the sedimentation tank 1. The mounting frame 2 is rotatably mounted within the sedimentation tank 1. A drain pipe 11 is vertically arranged within the sedimentation tank 1, coaxially arranged with the sedimentation tank 1. A receiving frame 12 is disposed at the upper end of the drain pipe 11, and the mounting frame 2 is rotatably engaged with the receiving frame 12. A driving component 13 is disposed on the receiving frame 12, which is a motor. The output end of the driving component 13 is connected to the mounting frame 2 to drive the mounting frame 2 to rotate. The mounting frame 2 is provided with a filter frame 3, a driving assembly 4, a squeezing assembly 5, and a collecting assembly 6. The driving component 13 drives the mounting frame 2 to rotate, while the driving assembly 4, in conjunction with the filter frame 3, cleans impurities in the sedimentation tank 1. Subsequently, the squeezing assembly 5 processes the collected impurities, discharging the water from the impurities. Finally, the collecting assembly 6 collects the impurities.

[0039] Reference Figure 1 , Figure 2 , Figure 7 Support wheels 21 are provided at the bottom of the mounting frame 2, and the support wheels 21 are rotatably mounted on the mounting frame 2. Support wheels 21 are also provided at both ends of the mounting frame. A support part 14 is provided circumferentially on the inner side of the sedimentation tank 1, and the support part 14 is coaxially arranged with the rotation axis of the mounting frame 2. The support wheels 21 are located between the mounting frame 2 and the support part 14, and the support wheels 21 are placed on the support part 14. When the mounting frame 2 rotates, the support wheels 21 rotate synchronously, and at the same time, the support wheels 21 support the mounting frame 2 to improve the stability of the mounting frame 2 during rotation.

[0040] Reference Figure 2 , Figure 3 , Figure 4 The filter frame 3 is slidably mounted on the mounting frame 2. An interception section 7 is located at the bottom of the filter frame 3, with multiple through holes, meaning the interception section 7 also functions as a filter. The interception section 7 is perpendicular to the filter frame 3, which rotates with the mounting frame 2. The interception section 7 is positioned on the side of the filter frame 3 closest to its rotation direction. The drive assembly 4 is connected to the filter frame 3 to move it up and down. The squeezing assembly 5 is positioned directly above the interception section 7 and above the water surface. The collecting assembly 6 is located to one side of the squeezing assembly 5.

[0041] The driving component 13 drives the mounting frame 2 to rotate, which in turn drives the filter frame 3 to rotate synchronously. As the filter frame 3 rotates, it filters impurities floating in the water. When the filter frame 3 moves upward, the intercepting part 7 at the bottom of the filter frame 3 intercepts the impurities, preventing them from falling off. Simultaneously, the up-and-down movement of the intercepting part 7 increases the agitation of the wastewater, ensuring more thorough mixing of the chemicals and wastewater. Furthermore, because the intercepting part 7 is horizontally positioned, its up-and-down movement disturbs the impurities at the bottom of the sedimentation tank 1, causing them to float in the water. During wastewater treatment, the intercepting part 7 and the filter frame 3 continuously perform circular motion within the sedimentation tank 1. After the intercepting part 7 disturbs and floats the impurities at the bottom of the sedimentation tank 1, these impurities can be collected and treated through the filter frame 3 and the intercepting part 7.

[0042] Reference Figure 4 , Figure 5The extrusion assembly 5 includes an elastic telescopic plate 51 and an extrusion plate 52. The extrusion plate 52 is located directly above the interception part 7 and is parallel to the interception part 7. The elastic telescopic plate 51 is a telescopic plate structure, specifically including an outer plate, an inner plate, and a spring. The outer plate is slidably disposed outside the inner plate, and the spring is disposed between the two, with its two ends connected to the inner plate and the outer plate respectively, so that the elastic telescopic plate 51 can extend and retract and has elasticity. The elastic telescopic plate 51 is located below the mounting frame 2, with its upper end connected to the mounting frame 2 and its lower end connected to the extrusion plate 52.

[0043] The drive assembly 4 moves the filter frame 3 up and down, and after moving the interception part 7 to the outside of the water surface, it continues to move the interception part 7 so that the interception part 7 is close to the squeezing plate 52. The squeezing plate 52 works together to squeeze the impurities on the interception part 7, removing the water from the impurities so as to avoid secondary processing of the impurities and facilitate the collection of the impurities.

[0044] Additionally, a squeezing plate 52 is provided on one side of the filter frame 3 that slides against the side of the filter frame 3. When the filter frame 3 moves upward past the squeezing plate 52, the squeezing plate 52 can scrape the impurities on the filter frame 3 to the interception part 7 so that the impurities can be fully squeezed.

[0045] Reference Figure 4 , Figure 5 The collection component 6 includes a pusher 61, a scraper 62, and a collection frame 63. The collection frame 63 has an opening. The pusher 61 is a cylinder. The upper end of the elastic telescopic plate 51 is slidably engaged with the bottom of the mounting frame 2. The output end of the pusher 61 is connected to the elastic telescopic plate 51, that is, the piston rod of the cylinder is connected to the elastic telescopic plate 51 to drive the elastic telescopic plate 51 to move left and right in the horizontal direction. The opening of the collection frame 63 is set upward, and the collection frame 63 is spaced apart from the filter frame 3. The scraper 62 includes a horizontal part 621 and a vertical part 622. That is, the vertical part 622 is set perpendicular to the horizontal part 621. The horizontal part 621 is connected to the extrusion plate 52. The vertical part 622 is set on the side of the horizontal part 621 near the filter frame 3, that is, the vertical part 622 is located between the extrusion plate 52 and the filter frame 3.

[0046] After the interception section 7 moves closer to the extrusion plate 52 and extrudes the impurities, the lower end of the vertical section 622 abuts against the upper surface of the interception section 7. At this time, the upper surface of the interception section 7 is flush with the opening of the collection frame 63. Then, the pusher 61 drives the elastic telescopic plate 51 to move closer to the collection frame 63. The movement of the elastic telescopic rod drives the extrusion plate 52 and the scraper 62 to move synchronously. That is, the extrusion plate 52 and the vertical section 622 both move horizontally relative to the interception section 7. While moving, the vertical section 622 pushes the impurities on the interception section 7 to the top of the opening of the collection frame 63, so that when the extrusion plate 52 moves to the top of the collection frame 63, the impurities can be transferred into the collection frame 63, thus completing the collection of impurities.

[0047] Reference Figure 4 , Figure 5 A slide rod 521 is provided above the extrusion plate 52. The slide rod 521 is arranged vertically. A horizontal part 621 is connected to the extrusion plate 52 via the slide rod 521, and the horizontal part 621 is sleeved on the outside of the slide rod 521. The horizontal part 621 and the slide rod 521 slide vertically in cooperation. A spring 522 is provided between the horizontal part 621 and the extrusion plate 52 to connect the two. The spring 522 is a spring.

[0048] Initially, the horizontal part 621 is close to the extrusion plate 52, and the lower end of the vertical part 622 is located below the extrusion plate 52. After the intercepting part 7 approaches the extrusion plate 52, the intercepting part 7 first abuts against the lower end of the vertical part 622. Then, the intercepting part 7 continues to move, causing the impurities to cooperate with the extrusion plate 52 and extrude the impurities. This ensures that the lower end of the vertical part 622 and the intercepting part 7 remain in contact during the extrusion process. Furthermore, a spring 522 is provided to elastically connect the horizontal part 621 and the extrusion plate 52, preventing the vertical part 622 from interfering with the movement of the intercepting part 7.

[0049] Reference Figure 4 , Figure 5 Multiple slide rods 521 are provided, and the multiple slide rods 521 are evenly distributed on the extrusion plate 52. By setting multiple slide rods 521 to cooperate with the horizontal part 621, the stability of the horizontal part 621 during movement is improved. A relief groove 623 is provided on the horizontal part 621. The horizontal part 621 is sleeved on the outside of the elastic telescopic plate 51, that is, the elastic telescopic plate 51 passes through the relief groove 623 and connects with the extrusion plate 52. The elastic telescopic plate 51 and the inner wall of the relief groove 623 are spaced apart. By setting the relief groove 623, the phenomenon of the horizontal part 621 interfering with the cooperation between the elastic telescopic plate 51 and the extrusion plate 52 is reduced.

[0050] Reference Figure 4 , Figure 6An intermediate frame 8 is provided at the upper end of the drain pipe 11, fitting around the outside of the drain pipe 11 and communicating with the interior of the drain pipe 11. An opening is provided on the intermediate frame 8 at its upper end. A collection frame 63 is arranged horizontally and oriented towards the rotation center of the mounting frame 2. One end of the collection frame 63 near the drain pipe 11 extends above the intermediate frame 8. A drain outlet 631 is provided at the bottom of the collection frame 63, located above the intermediate frame 8. A spiral conveyor plate 632 is rotatably arranged inside the collection frame 63, with its axis along the length of the collection frame 63. A motor (not shown in the figure) is also provided on the collection frame 63, and the output end of the motor is connected to the rotation shaft of the spiral conveyor plate 632.

[0051] After the impurities enter the collection frame 63, the spiral conveyor plate 632 rotates, causing the impurities in the collection frame 63 to enter the intermediate frame 8, and then enter the drain pipe 11 through the intermediate frame 8, where the impurities are collected.

[0052] Reference Figure 2 , Figure 3 The drive assembly 4 includes: a second drive component 41, a drive screw 42, and a first drive sleeve 43. The second drive component 41 is a motor. The drive screw 42 is arranged in the vertical direction, that is, the drive screw 42 is arranged in the moving direction of the filter frame 3. The first drive sleeve 43 is installed on the filter frame 3 and is sleeved on the outside of the drive screw 42. The first drive sleeve 43 is threadedly connected to the drive screw 42. The output end of the second drive component 41 is coaxially connected to the drive screw 42.

[0053] The second driving component 41 drives the driving screw 42 to rotate reciprocally. The rotation of the driving screw drives the first driving sleeve 43 to move. The movement of the first driving sleeve 43 drives the filter frame 3 to move. The filter screen moves up and down with the rotation direction of the driving screw 42, thereby realizing the up and down movement of the filter frame 3.

[0054] To improve the wastewater treatment effect, a spray pipe 9 is installed on the mounting frame 2. The spray pipe 9 includes multiple vertically arranged spray sections 91, and each spray section 91 has multiple spray holes 92 arranged vertically. When the mounting frame 2 rotates, it drives the spray pipe 9 to rotate synchronously. The rotation of the spray pipe 9 drives the spray sections 91 to rotate synchronously, and at the same time, the chemical is sprayed into the wastewater through the spray holes 92, so that the chemical comes into full contact with the wastewater and improves the wastewater treatment effect.

[0055] Reference Figure 2 , Figure 3Two sets of drive screws 42 are provided, one on each side of the mounting frame 2. A second drive sleeve 93 is mounted on the spray pipe 9, fitted onto the drive screws 42 and threadedly connected to them. Thus, the two sets of drive screws 42 respectively engage with the first drive sleeve 43 and the second drive sleeve 93. A second drive component 41 is positioned between the two sets of drive screws 42. A transmission belt 411 is located at the output end of the second drive component 41, simultaneously fitted around both sets of drive screws 42. This allows the second drive screw 42 to simultaneously drive both sets of drive screws 42 to rotate via the transmission belt 411, with the two sets rotating in opposite directions at the same time. When the filter frame 3 moves up and down, the spray pipe 9 also moves up and down simultaneously to evenly spray the medicine into the wastewater, ensuring full contact between the medicine and the wastewater.

[0056] The second driving component 41 moves the filter frame 3 up and down, and simultaneously moves the intercepting part 7 up and down. The frequency at which the intercepting part 7 moves upward to the outside of the sewage can be adjusted according to the collection of impurities on the intercepting part 7. In this embodiment, when the second driving component 41 drives the driving screw 42, which cooperates with the filter frame 3, to rotate forward, it moves the filter frame 3 downward; when the driving screw 42 rotates in reverse, it moves the filter frame 3 upward. During normal operation, the second driving component 41 drives the driving screw 42 to rotate forward and in reverse the same number of times, that is, the distance the filter frame 3 moves downward is the same as the distance it moves upward, and at this time, the intercepting part 7 is always inside the sewage. When it is necessary to clean the impurities on the intercepting part 7, the number of reverse rotations of the driving screw 42 is adjusted so that the distance the intercepting part 7 moves upward is greater than the distance it moves downward, so that the intercepting part 7 moves to the outside of the sewage, so that the intercepting part 7 cooperates with the squeezing plate 52 to squeeze the impurities. Specifically, in this embodiment, the filter frame 3 is configured to clean the interception section 7 once every time it rotates once within the sedimentation tank 1 along with the mounting frame 2. That is, after the filter frame 3 rotates once, the number of times the drive screw 42 reverses due to the drive component 41 increases, causing the interception section 7 to move to the outside of the sewage. At this time, impurities on the interception section 7 are cleaned. In addition, in the initial stage of sewage treatment, the impurities on the interception section 7 can be cleaned once every half rotation. The cleaning frequency of the interception section 7 can be adjusted adaptively according to the impurities in the sewage.

[0057] In addition, to facilitate monitoring of wastewater treatment progress, a torque sensor can be installed on the rotating shaft of the mounting frame 2. The torque sensor monitors the magnitude of the torque on the rotating shaft of the mounting frame 2. The magnitude of the torque on the rotating shaft of the mounting frame 2 corresponds to the amount of impurities in the wastewater. That is, when there are more impurities, there are more impurities on the filter frame 3, and the resistance it experiences when rotating with the mounting frame 2 is greater. At this time, the rotating shaft of the mounting frame 2 experiences a greater torque. As the impurities gradually decrease, the resistance experienced by the filter frame 3 during rotation also decreases. The data detected by the torque sensor can be used to monitor the removal of impurities, so as to promptly grasp the wastewater treatment progress.

[0058] Reference Figure 2 , Figure 3 The system comprises two sets of spray pipes 9 and filter frames 3. Within each set, the spray pipes 9 and filter frames 3 are positioned on opposite sides of the mounting frame 2, with the filter frames 3 arranged symmetrically around the rotation center of the mounting frame 2. Specifically, the spray pipes 9 in one set and the filter frames 3 in the other set are located on the same side of the mounting frame 2, and the interception part 7 is located on the side of the filter frame 3 closest to the spray pipes 9. When the mounting frame 2 rotates, it drives both sets of spray pipes 9 and filter frames 3 to rotate synchronously, resulting in a more complete reaction between the pesticide and wastewater, while simultaneously improving the efficiency of the filter frames 3 in collecting impurities.

[0059] Reference Figure 1 , Figure 8 An intercepting net 15 is installed on the inner wall of the sedimentation tank 1, with the net 15 positioned near the top of the sedimentation tank 1. An overflow channel 16 is formed in the side wall of the sedimentation tank 1, located between the intercepting net 15 and the side wall of the sedimentation tank 1. An overflow port 17, communicating with the overflow channel 16, is provided on the outer side of the sedimentation tank 1. The water level of the wastewater in the sedimentation tank 1 is level with the intercepting net 15. Excess wastewater is discharged through the overflow channel 16 and the overflow port 17. At the same time, the intercepting net 15 intercepts impurities floating on the wastewater, which can then be collected by a filter screen, while maintaining the water level of the wastewater in the sedimentation tank 1.

[0060] The implementation principle of this invention is as follows: Driver 13 drives the mounting frame 2 to rotate, and the rotation of the mounting frame 2 drives the spraying pipe 9 and the filter frame 3 to rotate simultaneously. At the same time, driver 21 drives two sets of drive screws 42 to rotate through the transmission belt 411, thereby driving the spraying pipe 9 and the filter frame 3 to move up and down simultaneously, and the two move in opposite directions. When the filter frame 3 moves up and down, it drives the interception part 7 to move up and down. When the filter frame 3 rotates with the mounting frame 2, it filters impurities in the sewage. At the same time, the interception part 7 moves up and down to filter impurities at the bottom of the sedimentation tank 1. The disturbance causes impurities at the bottom of the sedimentation tank 1 to float inside the sedimentation tank 1. These impurities are then filtered again by the continuously rotating filter frame 3. When the interception part 7 moves upward to the squeezing plate 52 and moves above the sewage, the interception part 7 works with the squeezing plate 52 to squeeze the impurities and remove the water from them. Then, the pusher 61 drives the elastic telescopic plate 51 to move, which in turn moves the squeezing plate 52 above the collection frame 63. At the same time, the vertical part 622 pushes the impurities into the collection frame 63 for subsequent collection.

[0061] By setting up a filter frame 3 that moves up and down and an interception part 7, impurities in the sewage are filtered out. At the same time, before collection, the squeezing plate 52 is used to treat the excess water contained in the impurities, so as to reduce the water content in the collected impurities, avoid secondary treatment of the impurities, and improve the collection efficiency of impurities.

[0062] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
