[0032] As Figure 1-Figure 4As shown in the figure, the blocking device 4 includes a bottom plate 41, which is fixedly connected to the inner wall of the housing 1. One end of the bottom plate 41 close to the driving motor 21 is provided with a groove. A plug board 43 is installed on the surface of the groove on the bottom plate 41. A filter board 42 is fixedly connected to the side of the plug board 43 away from the bottom plate 41. By providing the bottom plate 41 and the plug board 43, the installation and disassembly of the filter board 42 can be facilitated. By providing the filter board 42, solid debris can be blocked while not affecting the passage of sewage. Two fixing plates 45 are fixedly connected to the side of the housing 1. The inner walls of the two fixing plates 45 are both slidably connected with plug rods 46. Two arc-shaped plates 44 are fixedly connected to the side of the filter board 42 away from the plug board 43. By providing the fixing plates 45, the plug rods 46 can be connected to the housing 1. The plug rods 46 slidably connected to the inner walls of the fixing plates 45 can move.

[0033] A round plate 47 is fixedly connected to the end of the plug rod 46 away from the arc-shaped plate 44. A spring 48 is sleeved on the surface of the plug rod 46. The two ends of the spring 48 are respectively fixedly connected to the round plate 47 and the fixing plate 45. By providing the round plate 47, the movement of the plug rod 46 can be facilitated, and at the same time, the spring 48 can be installed. By providing the spring 48, the position of the plug rod 46 can be restricted.
[0034] As Figure 1-Figure 3 and Figure 5-Figure 7 As shown in the figure, the cleaning device 5 includes two scraping plates 54. The two scraping plates 54 are both slidably connected to the surface of the filter board 42. A limiting clamping plate 55 is fixedly connected to the side of the bottom plate 41 close to the scraping plate 54. Both sides of the scraping plate 54 are inclined surfaces, so that the surface of the filter board 42 can be conveniently cleaned. By providing the limiting clamping plate 55, the movement of the scraping plate 54 can be restricted to prevent the scraping plate 54 from rotating during operation. A control motor 51 is fixedly connected to the side of the housing 1. The output end of the control motor 51 is fixedly connected to a rotating rod 52. The other end of the rotating rod 52 is fixedly connected to a threaded rod 56. By providing the control motor 51, the rotating rod 52 can be controlled to drive the threaded rod 56 to rotate. The rotating rod 52 is rotatably connected to the inner wall of the housing 1, so that while not affecting the rotation of the rotating rod 52, the stability of the rotation of the rotating rod 52 can be ensured as much as possible.
[0035] Two threaded plates 57 are sleeved on the surface of the threaded rod 56, and two limiting rings 58 are fixedly connected to the surface of the threaded rod 56. The two threaded plates 57 are fixedly connected to the side close to the scraper 54 with the connecting rod 53, and the other end of the connecting rod 53 is fixedly connected to the scraper 54. Two opposite threads are provided on the surface of the threaded rod 56, so that the rotation of the threaded rod 56 can control the two threaded plates 57 to move away from or close to each other. By setting the limiting ring 58, the movement of the threaded plates 57 can be limited. The movement of the threaded plates 57 can drive the connecting rod 53 to move, thereby controlling the movement of the scraper 54.
[0036] Working principle: When using the rotary screen cleaner, first install the shell 1 to the position where the rotary screen cleaner is needed, then start the drive motor 21 of the drive mechanism 2 to drive the rotating rod 22 to rotate, and the rotation of the rotating rod 22 can drive the first pulley 23, so that the second pulley 25 rotates under the action of the transmission belt 24, and the rotation of the second pulley 25 can drive the transmission tooth roller 26 to rotate, thereby driving the tooth rake 3 to move on the surface of the transmission tooth roller 26, and the position of the tooth rake 3 can be limited by the limiting roller 27. Before using the rotary grille dirt remover, first pull the circular plate 47 to drive the plug rod 46 to slide on the inner wall of the fixed plate 45, so that the circular plate 47 moves away from the fixed plate 45, and then move the filter plate 42 to make the plug plate 43 move close to the bottom plate 41, loosen the circular plate 47, and under the action of the elastic force of the spring 48, the plug rod 46 moves close to the arc plate 44 to complete the installation of the filter plate 42. By setting the plug plate 43, it is convenient to install and disassemble the filter plate 42, thereby facilitating the cleaning of the filter plate 42 and avoiding the filter plate 42 as much as possible. When the rotary screen dirt remover is used, the solid debris picked up by the tooth rake 3 is not collected and passes through the screen. Under the obstruction of the filter plate 42, it is retained on the side of the filter plate 42 close to the tooth rake 3, thereby avoiding the solid debris from being mixed in the sewage as much as possible. By setting the blocking device 4, when the solid debris picked up by the tooth rake 3 is not collected and passes through the screen, the solid debris can be blocked, thereby avoiding the solid debris from being mixed in the sewage as much as possible and affecting the next step of sewage treatment.
[0037] When the rotary screen dirt remover is used, the control motor 51 is started, and the control motor 51 drives the rotating rod 52 to rotate, so that the threaded rod 56 rotates. The rotation of the threaded rod 56 causes the two threaded plates 57 on the surface of the threaded rod 56 to move toward each other. The movement of the threaded plate 57 can drive the scraper 54 to move on the surface of the filter plate 42 through the connecting rod 53, thereby cleaning the surface of the filter plate 42. By controlling the forward or reverse rotation of the control motor 51, the threaded plate 57 can be controlled to move closer to or away from the limit ring 58, so as to achieve comprehensive cleaning of the filter plate 42 as much as possible. By setting the limit card plate 55, the position of the scraper 54 can be limited. By setting the cleaning device 5, the surface of the filter plate 42 can be scraped while the filter plate 42 blocks solid debris, thereby avoiding the solid debris from adhering to the filter plate 42 as much as possible and affecting the passage of sewage through the filter plate 42.
