[0021] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0022] like Figure 1-Figure 4 As shown, the present embodiment provides a sewage sedimentation equipment with multiple filtering structures, including a treatment box 1, in which two groups of cleaning components 4 are installed, the cleaning component 4 is composed of a screw 401, a guide rod 402, a movable plate 403, a telescopic column 405, a spring 406 and a scraper 404, and a transmission component 5 is arranged on one side wall of the treatment box 1, the transmission component 5 is composed of a transmission box 501, a driving motor 504, a main gear 502 and a sub gear 503.

[0023] The screw 401 is rotatably installed between the inner walls of the processing box 1, the guide rod 402 is welded between the inner walls of the processing box 1, the movable plate 403 is connected to the screw 401 by threads, and the guide rod 402 passes through the movable plate 403. During the rotation of the screw 401, the movable plate 403 moves under the action of the threads and the guide rod 402.

[0024] The fixed part of the telescopic column 405 is fixedly connected to the movable plate 403, the spring 406 is welded to the outer wall of the telescopic column 405, the scraper 404 is connected to the movable end of the telescopic column 405 by screws, and a slag discharge plate 2 is fixed at the position corresponding to the processing box 1 and the cleaning component 4. The movable plate 403 drives the scraper 404 to move along the surface of the filter screen, and the impurities on the filter screen can be scraped uniformly to the slag discharge plate 2 for slag discharge. During the scraping process, the telescopic column 405 is combined with the spring 406 to enable the scraper 404 to have a buffer space for movement in the vertical direction.

[0025] The transmission box 501 is fixed to a side wall of the processing box 1 by bolts, and the output shaft of the driving motor 504 is fixedly connected to the main gear 502 , and the driving motor 504 drives the main gear 502 to rotate.

[0026] The main gear 502 is meshed with the sub-gear 503 , and the sub-gear 503 is fixedly connected to one end of the two sets of screw rods 401 respectively. The main gear 502 drives the sub-gear 503 to rotate, and the sub-gear 503 drives the screw rod 401 to rotate.

[0027] A first filter screen 7 and a second filter screen 8 are fixed in the treatment box 1 along the vertical direction. The filtering performance of the first filter screen 7 and the second filter screen 8 increases successively. The scraper 404 is in contact with the surface of the first filter screen 7 and the second filter screen 8. The first filter screen 7 and the second filter screen 8 can form a multi-layer filtering structure to filter impurities in the sewage.

[0028] A water inlet pipe 3 is reserved at the upper end of the treatment box 1 , and a drainage pipe 6 is reserved at the bottom end of one side wall of the treatment box 1 . Sewage enters the treatment box 1 through the water inlet pipe 3 for filtration, and the filtered sewage is discharged through the drainage pipe 6 .

[0029] The working principle of this device is as follows: the water inlet pipe 3 is connected to the external sewage pipe, and then the sewage enters the treatment box 1 through the water inlet pipe 3 for filtration. At this time, the first filter screen 7 and the second filter screen 8 can form a multi-layer filtration structure to filter impurities in the sewage, and the filtered sewage is discharged through the drain pipe 6. When the impurities on the surface of the filter screen need to be cleaned due to the decline in the filtering performance of the filter screen, the slag discharge plate 2 is removed, and the main gear 502 is driven to rotate by the driving motor 504. The main gear 502 drives the screw 401 in the cleaning component 4 to rotate through the sub-gear 503, and then the movable plate 403 drives the scraper 404 to move along the surface of the filter screen under the action of the thread and the guide rod 402, so that the impurities on the filter screen can be uniformly scraped to the slag discharge plate 2 for slag discharge. Compared with the traditional cleaning method of disassembling the filter screen, it has the advantages of simple cleaning process, time saving, labor saving and high cleaning efficiency.
