[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 4 As shown, a sewage screening device comprises a base 1 and a treatment chamber 2, wherein a screening filter plate 4 is fixedly installed obliquely in the treatment chamber 2 by bolts 3, a receiving box 5 is fixedly installed on one side of the treatment chamber 2, and a T-shaped through slot 7 is provided at the front and rear ends of the treatment chamber 2 above the screening filter plate 4, a cleaning assembly 8 is provided inside the T-shaped through slot 7, and the cleaning assembly 8 comprises a cylinder 16, the cylinder 16 is located inside the treatment chamber 2, a plurality of brushes 17 are fixedly installed on the outside of the cylinder 16, a waterproof motor 19 is fixedly installed on both sides of the cylinder 16, and one end of the output shaft of the waterproof motor 19 is fixedly installed There is a circular gear disk 20. First, the sewage is poured from the top of the treatment chamber 2. The sewage first contacts the screening filter plate 4. The screening filter plate 4 blocks the larger impurities in the sewage. Through the cleaning component 8, the screening filter plate 4 is easily blocked when it is used multiple times. At this time, the waterproof motor 19 is started. The waterproof motor 19 drives the circular gear disk 20 to rotate. The circular gear disk 20 is engaged with the rack 22 inside the T-shaped through groove 7. Therefore, the waterproof motor 19 drives the cylinder 16 to move, so that the brush 17 scrapes the screening filter plate 4 to prevent the screening filter plate 4 from being seriously blocked and inconvenient for sewage to pass through.

[0023] In this embodiment, a plurality of racks 22 are fixedly mounted on the inner bottom end of the T-shaped through slot 7 , the circular gear plate 20 is meshed and matched with the racks 22 , and the T-shaped through slot 7 is also obliquely arranged.

[0024] In this embodiment, an inclined guide plate 21 is fixedly installed inside the treatment chamber 2 below the screening filter plate 4, and a sewage guide plate 6 is connected to one side of the treatment chamber 2, and the sewage guide plate 6 is in communication with the inclined guide plate 21. After the sewage passes through the screening filter plate 4, it is received by the inclined guide plate 21 and finally discharged from the treatment chamber 2 from the sewage guide plate 6.

[0025] In this embodiment, the upper end of the material receiving box 5 is located below the screening filter plate 4 , and the brush 17 is in contact with the surface of the screening filter plate 4 .

[0026] In this embodiment, two groups of springs 9 are fixedly mounted on the upper end of the base 1 , each group of springs 9 has four springs, and the top of the spring 9 is fixedly connected to the lower end of the processing chamber 2 .

[0027] In this embodiment, three fixing blocks 13 are fixedly mounted on the upper end of the base 1 , a rotating motor 14 is fixedly mounted on one side of the fixing block 13 , and a cam 15 is fixedly mounted on one end of the output shaft of the rotating motor 14 .

[0028] In this embodiment, three fixed blocks 10 are fixedly installed at the lower end of the processing chamber 2, and a sleeve column 11 is fixedly installed on one side of the fixed block 10, and a sleeve ring 12 is movably engaged on the outside of the sleeve column 11, and the sleeve ring 12 is in conflict with the cam 15. Through the provided base 1, the rotating motor 14 on one side of the three fixed blocks 13 is started, and the rotating motor 14 drives the cam 15 to rotate, so that the cam 15 contacts the sleeve ring 12 outside the sleeve column 11. Due to the action of the spring 9, the entire processing chamber 2 vibrates, which facilitates impurities to pass through the screening filter plate 4 and fall into the inside of the receiving box 5. At the same time, it is convenient for sewage to quickly pass through the screening filter plate 4 and the inclined guide plate 21, so that the sewage is convenient for the next step of processing.

[0029] The implementation principle of a sewage screening device in the embodiment of the present application is as follows: the sewage first contacts the screening filter plate 4, the screening filter plate 4 blocks the larger impurities in the sewage, and after the sewage passes through the screening filter plate 4, it is received by the inclined guide plate 21 and finally discharged from the sewage guide plate 6 to the treatment chamber 2. Through the provided cleaning component 8, the mesh of the screening filter plate 4 is easily clogged when it is used multiple times. At this time, the waterproof motor 19 is started, and the waterproof motor 19 drives the circular gear plate 20 to rotate. The circular gear plate 20 is meshed with the rack 22 inside the T-shaped through groove 7, so the waterproof motor 19 drives the circular gear plate 20 to rotate. The column 16 moves to make the brush 17 scrape the screening filter plate 4 to prevent the screening filter plate 4 from being seriously blocked and inconvenient for sewage to pass through. The rotating motor 14 on one side of the three fixed blocks 13 is started through the provided base 1. The rotating motor 14 drives the cam 15 to rotate, so that the cam 15 contacts the collar 12 outside the sleeve column 11. Due to the action of the spring 9, the entire processing chamber 2 vibrates, which makes it easy for impurities to pass through the screening filter plate 4 and fall into the inside of the receiving box 5. At the same time, it is easy for sewage to quickly pass through the screening filter plate 4 and the inclined guide plate 21, so that the sewage is convenient for the next step of processing.
