[0019] The following is a clear and complete description of the present invention in conjunction with the accompanying drawings and embodiments:

[0020] like Figures 1 to 3As shown, a wastewater treatment device described in the utility model comprises a box body 1, one end of the two ends of the box body 1 is connected to an inlet pipe 2, and the other end is connected to a water outlet pipe 3; a transparent observation port 4 is provided on the box body 1 for observing and understanding the situation inside the box body 1, so as to intuitively grasp the situation inside the box body 1; an arc-shaped filter screen plate 5 is provided in the box body 1, and in the initial state, the arc-shaped inwardly concave side of the filter screen plate 5 faces one side of the water inlet pipe 2, so as to intercept solid dirt in the cavity enclosed by the filter screen plate 5, which is convenient for subsequent cleaning; the filter screen plate 5 is rotatably arranged in the box body 1 by a rotating shaft 6, and the rotating shaft 6 is coaxially arranged with the filter screen plate 5 and connected to the filter screen plate 5 by a connecting rod 7; a cleaning hole 8 is provided at the bottom of the box body 1 below the filter screen plate 5, and the cleaning hole 8 is arranged in a circular area coaxial with the rotating shaft 6, and the radius of the circular area is not greater than the radius of the filter screen plate 5, Preferably, two dirt holes 8 are provided and are arranged symmetrically. Each cleaning hole 8 is connected to a collecting bin 9 provided at the bottom of the box body 1. A discharge pipe 10 is provided at the bottom of the collecting bin 9. A valve is provided on the discharge pipe 10 to control the opening and closing of the collecting bin 9, so as to discharge dirt inside the collecting bin 9. A sealing plate 11 is coaxially provided on the rotating shaft 6 to block the cleaning hole 8. The sealing plate 11 may be a structure with the same shape as the cleaning hole 8 and a size slightly larger than the cleaning hole 8, or may be a disc-shaped structure. The disc-shaped structure adopted in this embodiment is provided with a through hole matching the cleaning hole 8. By rotating the sealing plate 11, the through hole and the cleaning hole 8 are misaligned or aligned to complete the sewage discharge or sealing operation. A scraper 12 is provided on the rotating shaft 6. The scraper 12 can scrape the solid dirt trapped at the front end of the filter screen plate 5 into the gradually opened cleaning hole 8 as the rotating shaft 6 rotates, so as to realize the dirt cleaning operation. Among them, in this embodiment, the sealing plate 11 is located in the collecting bin 9, and the sealing plate 11 is rotatably set on the bottom surface of the box body 1, and the scraper 12 is in contact with the inner bottom surface of the box body 1; in addition, two scrapers 12 are symmetrically arranged, and the two scrapers 12 are located in the sealing area between the two cleaning holes 8; when working, as the rotating shaft 6 rotates, the sealing plate 11 will gradually move, at this time the cleaning hole 8 will gradually open, and at the same time the scraper 12 will scrape the dirt into the cleaning hole 8 as the rotating shaft 6 rotates, thereby realizing the cleaning operation of the dirt.

[0021] Furthermore, baffles 13 are provided on both sides of the sealing plate 11, and blocks 14 are provided on the inner wall of the box body 1. In the initial state, the baffles 13 and the blocks 14 are tightly abutted to ensure sealing and prevent sewage from passing through the two sides of the filter screen plate 5. The two blocks 14 are arranged one in front of the other, that is, one of the two blocks 14 is located at the front end of the baffle 13 on one side, and the other is located at the rear end of the baffle 13 on the other side, so as to ensure sealing and prevent the rotation of the filter screen cylinder from being hindered. Cleaning bristles 15 are provided on the block 14 on the rear side, and the cleaning bristles 15 are in contact with the surface of the filter screen plate 5. When the rotating shaft 6 drives the filter screen cylinder to rotate, the cleaning bristles 15 will rub against the convex side of the filter screen plate 5, clean up the dirt adhering to the concave surface of the filter screen plate 5, and make it fall to the concave side of the filter screen plate 5 for subsequent centralized cleaning.

[0022] Furthermore, the top end of the rotating shaft 6 in this embodiment extends from the top of the box body 1, and a driven pulley 16 is arranged on it. The driven pulley 16 is connected to the driving pulley 18 arranged on the box body 1 through a transmission belt 17. The driving pulley 18 is connected to a motor 19 arranged on the box body 1. When it is necessary to clean the dirt, the motor 19 is controlled to drive the rotating shaft 6 to rotate. The purpose of cleaning the dirt can be achieved by controlling the forward and reverse rotation of the motor 19.

[0023] In addition, the rotating shaft 6 is a hollow structure, and a water inlet 20 is provided at its top; a cleaning hole is provided on the rotating shaft 6 located in the box body 1, which is used to be rotatably connected with an external water pipe to realize the cleaning operation of the box filter screen 5. Preferably, the cleaning hole is arranged on the side of the rotating shaft 6 opposite to the filter screen 5; and a nozzle is arranged in each cleaning hole to improve the cleaning effect of the filter screen 5 and ensure the filtering efficiency. When the filter screen 5 needs to be cleaned, a water pipe can be connected to the top of the rotating shaft 6 to transport clean water through a water pump, thereby realizing the cleaning operation of the filter screen 5, thereby enhancing the practicality of the utility model. In addition, in order to inspect and maintain the interior of the box body 1, a cover plate 21 is detachably provided on the top of the box body 1. In addition, since the treatment of wastewater requires multiple procedures, an aeration mechanism, a neutralization reaction mechanism and a deodorization mechanism are also provided in the box body 1 behind the filter screen plate 5 in this embodiment. Since the specific settings of this part are slightly different for wastewater of different components, and this part is a relatively mature prior art and does not fall within the scope of protection of this application, this part of the structure is not described in detail here.

[0024] When the utility model is in use, when wastewater flows through the filter screen 5, the dirt contained in the wastewater will be trapped by the filter screen 5 on the side close to the water inlet pipe 2. When a lot of dirt accumulates, the motor 19 can be started to drive the shaft 6 to rotate. As the shaft 6 rotates, the cleaning hole 8 will gradually open. At this time, the scraper 12 will move synchronously to scrape the dirt accumulated at the bottom of the box 1 into the cleaning hole 8; at the same time, the filter screen 5 will rotate and contact the cleaning bristles 15 to clean the dirt attached to its outer wall. Finally, the motor 19 drives the filter screen 5 and the sealing plate 11 to reset. The utility model can clean the dirt regularly without disassembling the equipment, which enhances the efficiency and convenience of wastewater treatment.
