[0028] Furthermore, a filter plate 11 is slidably mounted on the bottom end of the inner wall of the box body 1 . The filter plate 11 is sealed and connected to the inner wall of the box body 1 . The right end of the filter plate 11 is located outside the box body 1 .

[0029] Furthermore, a conical groove 12 is formed on the inner bottom surface of the box body 1 , a filter cartridge 13 is threadedly connected to the middle position of the lower end surface of the box body 1 , the filter cartridge 13 is connected to the inside of the box body 1 , and a multi-stage filter layer 14 is fixedly installed inside the filter cartridge 13 .

[0030] Furthermore, handles are fixedly mounted on both sides of the upper end surface of the filter box 5 and the right surface of the filter plate 11 .

[0031] Furthermore, an upper end cover 15 is provided on the upper end surface of the box body 1, and clamping rods are fixedly installed at the four corners of the upper end cover 15. Clamping grooves are opened at the positions of the upper end surface of the box body 1 corresponding to the clamping rods. The bottom ends of the clamping rods are plugged into the clamping grooves to cooperate with the upper end cover 15, and a water pipe 16 is fixedly installed on the upper end surface of the upper end cover 15.

[0032] Furthermore, the two fixed balls 9 are fixedly connected via a connecting rod 17 , and a handle 18 is fixedly mounted at a lateral middle position of the connecting rod 17 .

[0033] The sewage is discharged into the interior of the box 1 through the water pipe 16. After being filtered by the filter box 5, the sewage is filtered by the filter plate 11, flows into the filter cartridge 13 through the conical groove 12, and is filtered again by the multi-stage filter layer 14, and finally discharged through the filter cartridge 13.

[0034] When cleaning the filter box 5, the handle 18 is pulled forward to drive the connecting rod 17 to move forward, and then the two fixed balls 9 are moved. The movement of the fixed balls 9 drives the limit plate 7 to move through the slide rod 8, so that the limit plate 7 is separated from the upper end surface of the rectangular plate 6. At this time, the first spring 3 returns to its original state and drives the receiving plate 4 to move upward, and then drives the filter box 5 to move upward, so that the upper end surface of the filter box 5 moves upward to the top of the box body 1, so that the handle on the filter box 5 leaks out, which is convenient for the staff to pull the handle to pull out the filter box 5.

[0036] When installing the filter box 5, the rectangular plate 6 on the filter box 5 is aligned with the rectangular groove 2 on the box body 1 and inserted downward, so that the limit plates 7 on both sides move forward, and at the same time the second spring 10 extends. The filter box 5 moves downward, driving the rectangular plate 6 to move downward, and then the receiving plate 4 moves downward. The receiving plate 4 moves downward and drives the first spring 3 to contract. When the upper end surface of the rectangular plate 6 moves downward to the bottom of the limit plate 7, the second spring 10 returns to its original state and drives the slide bar 8 to move backward, thereby clamping the limit plate 7 on the upper end surface of the rectangular plate 6, and then limiting the filter box 5 through the limit plate 7 and the receiving plate 4.

[0037] Working principle:

[0038] When in use, the sewage is discharged into the interior of the box 1 through the water pipe 16. After being filtered by the filter box 5, the sewage is filtered by the filter plate 11, flows into the filter cartridge 13 through the conical groove 12, and is filtered again by the multi-stage filter layer 14, and finally discharged through the filter cartridge 13.

[0039] When cleaning the filter box 5, the handle 18 is pulled forward to drive the connecting rod 17 to move forward, and then the two fixed balls 9 are moved. The movement of the fixed balls 9 drives the limit plate 7 to move through the slide rod 8, so that the limit plate 7 is separated from the upper end surface of the rectangular plate 6. At this time, the first spring 3 returns to its original state and drives the receiving plate 4 to move upward, and then drives the filter box 5 to move upward, so that the upper end surface of the filter box 5 moves upward to the top of the box body 1, so that the handle on the filter box 5 leaks out, which is convenient for the staff to pull the handle to pull out the filter box 5.

[0040] The filter plate 11 is pulled out of the housing 1 to clean the impurities on the filter plate 11. The filter cartridge 13 is screwed out of the bottom of the housing 1 to replace the filter cartridge 13.

[0041] When installing the filter box 5, the rectangular plate 6 on the filter box 5 is aligned with the rectangular groove 2 on the box body 1 and inserted downward, so that the limit plates 7 on both sides move forward, and at the same time the second spring 10 extends. The filter box 5 moves downward, driving the rectangular plate 6 to move downward, and then the receiving plate 4 moves downward. The receiving plate 4 moves downward and drives the first spring 3 to contract. When the upper end surface of the rectangular plate 6 moves downward to the bottom of the limit plate 7, the second spring 10 returns to its original state and drives the slide bar 8 to move backward, thereby clamping the limit plate 7 on the upper end surface of the rectangular plate 6, and then limiting the filter box 5 through the limit plate 7 and the receiving plate 4.

[0042] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
