[0001] The present application relates to the technical field of filter devices, and in particular to a wastewater treatment filter device. Background Art

[0002] Sewage refers to water that has been polluted to a certain extent, and comes from life or production, and has lost its original use function. In addition, some production sewage cannot be discharged directly and needs to be treated.

[0003] Sewage treatment is divided into multiple treatment links. First, the sewage needs to be roughly filtered to filter out the larger stains in the sewage, and then subsequent treatment is carried out. The filter device used for the rough filtration of sewage is composed of a filter box, a filter plate, a water inlet pipe, a drain pipe and other structures. In order to ensure the filtering effect, the filter plate needs to be cleaned regularly. The existing filter plate is cumbersome to clean. The filter plate needs to be disassembled or the cleaning mechanism needs to be extended into the filter box to complete the cleaning; and the valve of the water inlet pipe needs to be manually closed when cleaning. In view of this, the present application proposes a wastewater treatment filter device. Summary of the invention

[0004] The purpose of this application is to propose a wastewater treatment filtration device in response to the technical problems pointed out in the background technology.

[0005] The technical solution of the present application is a wastewater treatment filter device, comprising a filter box, the upper end of which is provided with a through opening, the through opening is connected with a filter cartridge extending to the inside of the filter box, the upper and lower ends of the side walls of the filter box are respectively connected with a water inlet pipe and a drain pipe, and further comprising:

[0006] A valve and a switch plate are arranged at the input end of the water inlet pipe;

[0007] Control parts, used to control the opening and closing of the valve;

[0008] A cover plate is arranged at the upper end of the filter cartridge, and a dirt cleaning assembly is connected to the bottom end of the cover plate. The control member rises and falls synchronously with the cover plate.

[0009] Preferably, the cleaning assembly comprises a connecting rod fixedly connected to the lower surface of the cover plate, and the bottom end of the connecting rod is fixedly connected to a storage plate located at the bottom of the filter cartridge.

[0010] Preferably, filter plates are provided on the inner walls on both sides of the filter cartridge for filtering stains, and a plurality of water outlet pipes are connected to both sides of the lower end of the filter cartridge.

[0033] It also includes a control member 6 for controlling the opening and closing of the valve 4 , and the offset state of the switch plate 5 is controlled by moving the control member 6 upward or downward.

[0034] It also includes a cover plate 8 arranged at the upper end of the filter cartridge 9, the upper end of the filter box 1 is fixedly connected with an L-shaped plate 2, and the upper inner wall of the L-shaped plate 2 is installed with an electric telescopic rod 7, and the electric telescopic rod 7 is preferably a pair and symmetrically arranged; the telescopic end of the electric telescopic rod 7 is fixedly connected to the cover plate 8, and the cover plate 8 can completely cover the upper end of the through-port to prevent the sewage from splashing upward when entering the filter cartridge 9, and the bottom end of the cover plate 8 is connected to a cleaning component 11, and the control member 6 rises and falls synchronously with the cover plate 8. The cleaning component 11 includes a connecting rod 111 fixedly connected to the lower surface of the cover plate 8, and the connecting rod 111 is preferably a pair and symmetrically arranged at the bottom end of the cover plate 8, and the bottom end of the connecting rod 111 is fixedly connected to a storage plate 112 located at the bottom of the filter cartridge 9. The inner walls on both sides of the filter cartridge 9 are provided with filter plates 13 for filtering stains. The storage plate 112 is located between the two filter plates 13, and the two ends of the storage plate 112 are in contact with the two filter plates 13 respectively, and the storage plate 112 can slide in the two filter plates 13. The lower end of the filter cartridge 9 is connected to a plurality of water outlet pipes 14 on both sides, and the input end of the water outlet pipe 14 is located on the outside of the filter plate 13. A pair of drainage plates 10 are fixedly connected to the inner wall of the upper end of the filter box 1. The two drainage plates 10 are respectively located on both sides of the two groups of water outlet pipes 14 to drain the filtered water. The bottom end of the drainage plate 10 is spaced apart from the inner wall of the lower end of the filter box 1 to keep the water level of the filter box 1 consistent.

[0035] Specifically, the control member 6 includes a vertical plate 601 fixedly connected to the side wall of the cover plate 8, the vertical plate 601 is connected to the cover plate 8 through a connecting rod, and a pair of protrusions 602 are fixedly connected to the side of the vertical plate 601 close to the switch plate 5, and the two protrusions 602 are respectively located above and below the switch plate 5. Both protrusions 602 are made of silicone to prevent damage to the switch plate 5 caused by repeated contact with the switch plate 5.

[0036] The working principle of this embodiment is as follows: the external sewage discharge pipe is connected to the input end of the water inlet pipe 3, so that the discharged sewage first enters the filter cartridge 9, and the filter plate 13 on the inner wall of the filter cartridge 9 blocks the stains in the sewage in the filter cartridge 9, and the filtered water in the filter cartridge 9 is discharged into the filter box 1 through two sets of outlet pipes 14. By arranging a pair of drainage plates 10 in the filter box 1, the two drainage plates 10 can guide the water discharged from the two sets of outlet pipes 14, and prevent the discharged sewage from splashing in the filter box 1 due to the height difference to generate bubbles. The coarsely filtered water in the filter box 1 is discharged through the drain pipe 15 and then processed in the next step. The stains in the filter cartridge 9 can be cleaned regularly according to needs. When cleaning, the electric telescopic rod 7 is started, and the telescopic end of the electric telescopic rod 7 is retracted to drive the cover plate 8 to move upward. When the cover plate 8 moves upward, it will drive the storage plate 112 to move upward through the connecting rod 111, and lift the stains in the filter cartridge 9 to the upper end of the filter box 1 for easy processing.

[0037] When the cover plate 8 moves upward, it will drive the vertical plate 601 to move upward. The upward movement of the vertical plate 601 drives the upper protrusion 602 away from the switch plate 5, and makes the lower protrusion 602 move upward and finally contact with the switch plate 5 and push the switch plate 5, so that the switch plate 5 is offset upward by a certain angle, so that the valve 4 is closed. When cleaning the garbage in the filter cartridge 9, the valve 4 is automatically closed to prevent sewage from continuing to enter the filter cartridge 9, and there is no need to manually close the valve.
