[0024] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a filtration device with cleaning function.

[0025] like Figures 1 to 5 As shown, this utility model discloses a filtration device with a cleaning function, comprising a filter box 1, a filter screen 4 disposed within the filter box 1, and an inlet pipe 2 and an outlet pipe 3 connected to the filter box 1, with the inlet pipe 2 and outlet pipe 3 located above and below the filter screen 4, respectively. Wastewater enters the filter box 1 through the inlet pipe 2 and flows downward naturally under gravity. During its downward flow, the wastewater passes through the filter screen 4 to complete solid-liquid separation, and the filtered liquid is discharged through the outlet pipe 3.

[0026] To facilitate cleaning of the filter screen 4, the filter screen 4 is rotatably mounted inside the filter box 1 via a support shaft, and a drive device for rotating the filter screen 4 is provided on the outer wall of the filter box 1. The support shaft for supporting the filter screen 4 passes through the filter box 1, and the drive device is connected to the outer end of the support shaft. This allows the drive device to rotate the filter screen 4 inside the filter box 1 via the support shaft. Of course, the filter box 1 also has a cleaning assembly 5 for cleaning the filter screen 4. When the filter screen 4 rotates to an appropriate angle inside the filter box 1, the cleaning assembly 5 can be activated to clean the rotated filter screen 4, thereby removing impurities from the filter screen 4, saving time and effort and improving work efficiency. Specifically, the cleaning assembly 5 includes support rods 51 parallel to each other inside the filter box 1, water distribution pipes 52 spaced apart between two support rods 51, and multiple water spray pipes 53 connected to each water distribution pipe 52. Each water distribution pipe 52 is connected to a connecting pipe 54 that penetrates the top surface of the filter box 1. A water tank 56 is located on the side wall of the filter box 1. The connecting pipes 54 are connected to a water pump inside the water tank 56, which is powered by an external power source. The water pump in the water tank 56 delivers the cleaning solution to the water distribution pipes 52 via the main pipe 55 and the connecting pipes 54. The solution then flows from the water distribution pipes 52 to the spray pipes 53, which sprays it onto the filter screen 4. After being rinsed by the cleaning solution, the filter screen 4 is cleaned of impurities.

[0027] Preferably, a connecting plate 11 is provided between the middle of the two support rods 51, and guide rods 6 are provided at both ends of the support rods 51 inside the filter box 1. The connecting plate 11 and the guide rods 6 are slidably arranged, so that the cleaning component 5 can slide inside the filter screen 4 through the guide rods 6, thereby increasing the working range of the cleaning component 5 and enabling the cleaning component 5 to perform comprehensive cleaning of the filter screen 4. In order to realize the movement of the cleaning component 5, a first motor 7 connected to an external power supply is also provided on the top surface of the filter box 1. The first motor 7 is connected to the connecting plate 11 through a reciprocating mechanism. The reciprocating mechanism for connecting the first motor 7 and the connecting plate 11 includes a rotating shaft rotatably provided on the top surface of the filter box 1. The rotating shaft is vertically provided on the filter box 1 and passes through the top surface of the filter box 1. The top end of the rotating shaft is connected to the output end of the first motor 7. A disc 8 is provided on the bottom surface of the rotating shaft, and an eccentric shaft 9 is eccentrically provided on the bottom surface of the disc. A mounting frame 10 is provided on the top surface of the connecting plate 11, and the eccentric shaft 9 can be inserted into the mounting frame 10. When the cleaning component 5 needs to move within the filter box 1, the first motor 7 can be started. The first motor 7 drives the disc 8 through the rotating shaft. The rotation of the disc 8 will drive the eccentric shaft 9 to rotate around the center of the disc 8. With the cooperation of the rotating shaft and the mounting frame 10, the connecting plate 11 will cause the cleaning component 5 to slide on the guide rod 6, so as to increase the cleaning range of the water spray pipe 53 on the filter screen 4. That is, the cleaning component 5 can move left and right within the filter box 1.

[0028] Of course, to increase the spray range of the water spray pipe 53 within the filter box 1, and to enable the water spray pipe 53 to perform more comprehensive cleaning of the filter screen 4, a detachable mounting buckle 12 is provided on the support rod 51 corresponding to the position of each water distribution pipe 52, and the water distribution pipe 52 is rotatably mounted within the mounting buckle 12. In this embodiment, the mounting buckle 12 consists of two symmetrically arranged L-shaped frames and an arc-shaped frame for connecting the tops of the two L-shaped frames. The water distribution pipe 52 is rotatably mounted within the arc-shaped frame and the two L-shaped frames, and the two L-shaped frames are detachably connected to the support rod 51 by bolts, facilitating subsequent disassembly, assembly, and maintenance of the water distribution pipe 52 on the support rod 51.

[0029] like Figure 3 and Figure 4 As shown, each of the water distribution pipes 52 is equipped with a rotating assembly inside the filter box 1, which drives the water distribution pipe 52 to rotate. The rotating assembly includes a first support arm 13 located on the inner wall of the filter box 1, and first protrusions 14 spaced apart on the side wall of the first support arm 13. A mounting block 16 is located on the side wall of the support rod 51, and a guide rod 15 is located at one end of the water distribution pipe 52 and perpendicular to the axis of the water distribution pipe 52. A second protrusion 17 is provided on the guide rod 15, and a spring 18 is provided between the mounting block 16 and the second protrusion 17. When the first motor 7 drives the cleaning assembly 5 to move towards the first support arm 13 via the reciprocating mechanism, the guide rod 15 will rotate towards the mounting block 16 under the action of the first protrusion 14 of the first support arm 13. Under the action of the spring 18, the guide rod 15 will rotate towards the first support arm 13 along the outer contour of the first protrusion 14. This allows the water distribution pipe 52 to reciprocate on the support rod 51 under the limit of the mounting buckle 12, so that the water spray pipe 53 will reciprocate around the axis of the water distribution pipe 52, thereby increasing the range of the water spray pipe 53 spraying cleaning liquid, further improving the cleaning effect on the filter screen 4, and improving the cleaning efficiency of the filter screen 4.

[0030] To facilitate the maintenance and disassembly of the cleaning component 5, the filter box 1 consists of a box body and a top cover. The top of the box body is open, and the top cover is used to seal the opening of the filter box 1. The top cover and the box body are detachably connected by bolts.

[0031] like Figure 2As shown, the drive device for rotating the support shaft includes a second motor 19 located on the side wall of the filter screen 4 and connected to an external power supply. The second motor 19 is connected to the support shaft of the filter screen 4 via a transmission part. The transmission part includes a first gear 20 on the second motor 19 and a second gear 21 located at the outer end of the support shaft. The first gear 20 and the second gear 21 mesh. When the second motor 19 drives the first gear 20 to rotate, the first gear 20 drives the second gear 21 to rotate. The rotation of the second gear 21 drives the support shaft to rotate, and the rotation of the support shaft causes the filter screen 4 to rotate within the filter box 1. In this embodiment, it is preferable to rotate the filter screen 4 180 degrees, so that the filter surface of the filter screen 4 is flipped 180 degrees. When the cleaning component 5 cleans the filter screen 4, the impurities on the filter surface of the filter screen 4 are directly rinsed clean. Of course, in order to discharge the rinsed impurities from the filter screen 4 from the filter box 1, a drain pipe 26 is connected to the water outlet pipe 3. Meanwhile, a first control valve and a second control valve are respectively installed on the water outlet pipe 3 and the sewage discharge pipe 26. The filtered sewage is discharged through the water outlet pipe 3 to reduce the impact of impurities on it. When the first control valve on the water outlet pipe 3 is open, the second control valve on the sewage discharge pipe 26 will be closed; conversely, when the first control valve is closed, the second control valve will be open to prevent impurities from entering the drain pipe. It should be noted that the filter screen 4 will not collide with the cleaning assembly 5 during rotation, and the distance between the filter screen 4 and the cleaning assembly 5 is sufficient for the filter screen 4 to rotate. Furthermore, to protect the first and second motors, protective covers for both motors are removable by bolts on the filter box.

[0032] Specifically, the first control valve includes a first connecting rod 23 rotatably mounted on the outlet pipe 3, and a valve plate mounted on the first connecting rod 23, with the first connecting rod 23 passing through the outlet pipe 3. A second support arm 22 is provided on the outer wall of the filter box 1, with the first connecting rod 23 passing through and rotatably mounted thereto. A large gear 24 meshing with a second gear 21 is located at the top of the first connecting rod 23. When the second gear 21 rotates, the large gear 24 meshing with it rotates, and the first connecting rod 23 connected to it also rotates, causing the first valve plate 25 on the first connecting rod 23 to rotate, thereby controlling the opening and closing of the outlet pipe 3.

[0033] The second control valve controlling the opening and closing of the sewage pipe 26 includes a second connecting rod 28 rotatably disposed within the sewage pipe 26, and a second valve plate 30 disposed on the second connecting rod 28. The second connecting rod 28 passes through the sewage pipe 26, and a second bevel gear 29 is disposed at its outer end. A first bevel gear 27 is disposed at the bottom end of the first connecting rod 23, and the first bevel gear 27 and the second bevel gear 29 mesh with each other. When the first connecting rod 23 rotates, the first bevel gear 27 at its bottom end rotates, and the second bevel gear 29 meshing with it also rotates accordingly. This causes the second connecting rod 28 connected to the second bevel gear 29 to rotate, resulting in the rotation of the second valve plate 30 on the second connecting rod 28.

[0034] It should be noted that when the filter surface of filter screen 4 is in the upward position, the first valve plate 25 is open, while the second valve plate 30 is closed. This facilitates the discharge of impurities and cleaning fluid from filter screen 4 through drain pipe 26, reducing the impact on the drain pipe. Furthermore, the diameter of the large gear 24 is larger than the diameter of the second gear 21, so that after filter screen 4 rotates 180 degrees, the first valve plate 25 and the second valve plate 30 will only rotate 90 degrees.

[0035] Instructions for use: Wastewater enters the filter box 1 through the inlet pipe 2. Under gravity, the wastewater flows towards the filter screen 4 and is filtered through it before continuing to flow downwards. The filtered wastewater is then discharged through the drain pipe. When cleaning the filter screen 4, the second motor 19 is started. The second motor 19 drives the filter screen 4, connected to the support shaft, to rotate 180 degrees within the filter box 1 via the transmission unit. Simultaneously, the first valve plate 25 rotates 90 degrees under the action of the large gear 24 and the first connecting rod 23, thus sealing the outlet pipe 3. The second connecting rod 28, under the action of the first bevel gear 27 and the second bevel gear 29, drives the second valve plate 30 to rotate 90 degrees, opening the drain pipe 26. Then, the first motor 7 and the water pump in the water tank 56 are started. The first motor 7, through a reciprocating mechanism, drives the cleaning component 5 to move back and forth within the filter box 1, beginning the cleaning of the filter screen 4. The cleaned impurities and cleaning solution are discharged through the drain pipe 26. After the filter screen 4 is cleaned, the first motor 7 and the water pump stop working, while the second motor 19 rotates in the opposite direction, driving the filter screen 4 to rotate back to its initial position via the transmission unit. The first valve plate 25 and the second valve plate 30 also rotate back to their initial positions to continue filtering the wastewater.
