It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0024] like Figure 1-4 As shown, the utility model proposes an anti-blocking sewage treatment device, comprising a semicircular shell 1, a driving motor 2 is fixedly installed at the center of the semicircular shell 1, and a circular filter screen 3 is fixedly mounted on the driving shaft of the driving motor 2;

[0025] The semicircular shell 1 is provided with a cleaning mechanism 4 which is in transmission with the circular filter screen 3, and the cleaning mechanism 4 blows air toward the circular filter screen 3 for cleaning;

[0026] It also includes a guide-out mechanism 5 located at the water-facing surface of the circular filter screen 3 .

[0027] In an optional embodiment, the cleaning mechanism 4 includes a rotating box 41, a rotating tube 42, a notched tube 43, a mounting plate 44 and a partition plate 45. The rotating tube 42 is fixedly connected to the rotating box 41, and the partition plate 45 is fixedly installed inside the rotating box 41 and divides the interior of the rotating box 41 into a plurality of air intake channels. The air intake channels form air inlets on the outer periphery of the rotating box 41 (the air intake channels are connected to the rotating tube 42, and the bottom end of the rotating tube 42 is a closed end). A partition plate 45 located at each air intake extends out of the rotating box 41 to form an air guide portion. The rotating tube 42 is rotatably sleeved with the mounting plate 44, and the mounting plate 44 is fixedly connected to the notched tube 43. The notched tube 43 is located on the outer periphery of the rotating tube 42. A spray hole is opened on the rotating tube 42. The notched tube 43 is fixedly connected to the semicircular shell 1 through the mounting frame 46, and the rotating tube 42 is transmitted to the circular filter 3.

[0028] The notch of the notch tube 43 faces the air inlet, so that when the rotating tube 42 rotates and the spray hole is located at the notch, air is blown toward the circular filter screen 3 .

[0029] Furthermore, the driving shaft of the driving motor 2 and the rotating tube 42 are both fixedly mounted with bevel gears 47 that transmit transmission to each other.

An inlet is formed on one side of the arc box 51. The scraper 52 is fixedly mounted at the inlet for scraping the water-facing surface of the circular filter screen 3. The inlet corresponds to the rotating tube 42. An outlet is provided at the end of the arc box 51 away from the inlet.

[0031] Furthermore, a discharge pipe 53 is fixedly connected to the discharge outlet.

[0032] It should be noted that the inner bottom wall of the arc box 51 is inclined toward the discharge pipe 53 to facilitate the discharge of waste chips.

[0033] In an optional embodiment, valves are provided on both sides of the semicircular shell 1.

[0034] It should be noted that sewage can be added and liquid can be discharged through valves.

[0035] In the utility model, sewage is introduced from the liquid inlet side of the semicircular shell 1, and the driving motor 2 is started. The driving motor 2 drives the circular filter screen 3 to rotate, and the circular filter screen 3 can perform rotational filtering. While the circular filter screen 3 rotates, the rotating tube 42 is driven to rotate through the conical gear 47. The rotating box 41 rotates to take in air, and the air is sprayed out through the spray holes on the rotating tube 42 to act on the circular filter screen 3 to clean the waste debris in the mesh. The waste debris enters the arc box 51 and is discharged, which ensures the cleanliness of the circular filter screen 3 and increases the continuity of filtration.
