DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of the sewage filtering device provided by the utility model; Figure 2 for Figure 1 An enlarged schematic diagram of part A is shown; Figure 3 for Figure 1 The enlarged schematic diagram of part B is shown. The sewage filtering device comprises: a housing 1;

[0022] A processing chamber 2 is provided inside the shell 1, the processing chamber 2 is rotatably connected to a rotating shaft 3, the outer surface of the rotating shaft 3 is fixedly connected to two partitions 4, the outer surface of the rotating shaft 3 is provided with a filter plate 5, the top of the shell 1 is provided with a sewage inlet 6, the inside of the shell 1 is provided with a solid storage chamber 7 and a liquid storage chamber 8, the bottom of the processing chamber 2 is provided with a first through hole 9 and a second through hole 10, the first through hole 9 is connected to the solid storage chamber 7, and the second through hole 10 is connected to the liquid storage chamber 8.

[0023] The rotating shaft 3 is driven by an external driving motor and can be controlled to rotate by a control switch.

[0024] A telescopic cover plate 11 is disposed inside the sewage inlet 6 , a first discharge trough 12 is disposed on the left side of the solid storage chamber 7 , and a second discharge trough 13 is disposed on the right side of the liquid storage chamber 8 .

[0025] The telescopic cover 11 is provided to control the opening and closing of the sewage inlet 6 .

[0026] A groove 14 is provided on the outer surface of the rotating shaft 3, and the filter plate 5 is slidably connected to the inside of the groove 14. Compression springs 15 are provided between the top and bottom of the filter plate 5 and the top and bottom of the inner wall of the groove 14. Blocking blocks 16 are fixedly connected to the top and bottom of the filter plate 5, and two sealing grooves 17 are provided on the rotating shaft 3.

[0027] The filter plate 5 is arranged inside the groove 14 and cooperates with the compression spring 15 so that the filter plate 5 can slide up and down, and the blocking block 16 is inside the sealing groove 17. During the up and down sliding process of the filter plate 5, the blocking block 16 is always inside the sealing groove 17, which can seal the groove 14 and prevent solid waste from entering the interior of the groove 14.

[0028] The blocking block 16 is matched with the sealing groove 17 , and the blocking block 16 is slidably connected to the inside of the sealing groove 17 .

[0029] A receiving groove 18 is provided inside the shell 1, and the receiving groove 18 is communicated with the processing chamber 2. A gas support rod 19 is installed inside the receiving groove 18. A moving plate 20 is fixedly connected to the bottom of the gas support rod 19. A fixed frame 21 is fixedly connected to the bottom of the moving plate 20. A sliding plate 22 is slidably connected inside the fixed frame 21. A connecting block 23 is fixedly connected to the bottom of the sliding plate 22. A mounting plate 24 is fixedly connected to the bottom of the connecting block 23. A plurality of clearing needles 25 are provided at the bottom of the mounting plate 24.

[0030] The dredging needles 25 are matched with the filter holes of the filter plate 5, and the spacing is the same as that of the filter holes, and the positions are aligned.

[0031] As the rotating shaft 3 rotates, the filter plate 5 realizes a circular motion, the left filter plate 5 rotates rightward to the right filter plate 5 position, and the right filter plate 5 rotates leftward to the left filter plate 5 position, so that the solid waste is discharged from the first through hole 9. At this time, the filtering side of the filter plate 5 will be at the bottom, and the solid waste attached to the filter plate 5 and blocked in the filter hole will also be discharged by gravity.

[0032] Even if the solid waste is severely clogged and cannot fall by gravity, the moving plate 20 can be moved downward by extending the gas strut 19, so that the mounting plate 24 contacts the filter plate 5, and the dredging needle 25 extends into the filter hole of the filter plate 5 for dredging. The rotation of the circular plate 26 will drive the sliding plate 22 to move up and down through the movable rod 27, thereby causing the mounting plate 24 to move up and down. The sliding connection between the filter plate 5 and the groove 14 allows the filter plate 5 to move up and down, thereby vibrating the filter plate 5, shaking out the clogged solid waste, and improving the dredging effect.

[0033] A circular plate 26 is rotatably connected inside the fixed frame 21 . The circular plate 26 is located on the top of the sliding plate 22 . A movable rod 27 is rotatably connected to the front of the circular plate 26 . The bottom of the movable rod 27 is movably connected to the top of the sliding plate 22 .

[0034] The circular plate 26 is driven by an external driving motor and can be controlled to rotate by a control switch.

[0035] The working principle of the sewage filtering device provided by the utility model is as follows:

[0036] Sewage enters the treatment chamber 2 from the sewage inlet 6, and is blocked by the two partitions 4 so that the sewage is filtered through the filter plate 5 on the right, and the solid waste remains on the top of the filter plate 5. The sewage passes through the filter plate 5 and enters the liquid storage chamber 8 from the second through hole 10. The filter plate 5 rotates 180° counterclockwise by rotating the rotating shaft 3, so that the solid waste on the top is discharged downward into the solid storage chamber 7, and the filter plate 5 on the left is moved to the right for use.

[0037] Compared with the related art, the sewage filtering device provided by the utility model has the following beneficial effects:

[0038] The present invention can avoid clogging of the filter plate 5 by rotating the two filter plates 5, so that the filter plate 5 will not be blocked and scrapped, reducing the cost of use, and during the rotation of the filter plate 5, the solid waste can be discharged in time, avoiding the residual solid waste from affecting the water permeability, thereby improving the sewage treatment effect.
