[0023] Reference Figure 1 , Figure 2 and Figure 3As shown, a disc-type microporous aerator comprises an aerator shell 1 and a membrane cover 2, wherein the membrane cover 2 is mounted on the aerator shell 1 and the membrane cover 2 is sealed and fixedly connected to the aerator shell 1, an air inlet pipe 3 is mounted at the center of the lower end of the aerator shell 1, the air inlet pipe 3 is integrally formed with the aerator shell 1, and a check valve is mounted at the head of the air inlet pipe 3, a rotary scraper assembly 4 is also mounted in the air inlet pipe 3, the rotary scraper assembly 4 comprises a rotating part 41 and a side scraper part 42, the rotating part 41 is rotatably mounted in the air inlet pipe 3, the side scrapers 42 are symmetrically mounted on both sides of the rotating part 41, and the side scrapers 42 are slidably connected to the rotating part 41 in a radial direction, and a support spring 420 is also mounted between the side scraper part 42 and the rotating part 41. By installing the membrane cover 2 on the aerator shell 1, it is convenient to exhaust and supply oxygen through the micropores on the membrane cover 2. At the same time, the setting of the air inlet pipe 3 facilitates the connection of the air pipe for blowing air. The installation of the check valve makes it convenient to close the air inlet pipe 3 in time after stopping the fan to prevent backflow. The structural setting of the rotary scraper assembly 4 ensures that the rotating part 41 is installed in the air inlet pipe 3 for rotation. During the air intake process, the rotating part can drive the side scraper 42 to scrape the inner wall of the air inlet pipe 3 to prevent impurities from adhering to the inner wall of the air inlet pipe 3 and affecting the normal blowing of air into the air inlet pipe 3. By installing a support spring 420 between the side scraper 42 and the rotating part 41, it is ensured that the outer end of the side scraper 42 can fit tightly against the inner wall of the air inlet pipe 3 to ensure more thorough cleaning.

[0024] Reference Figure 4 and Figure 5 As shown, the rotating part 41 includes a central axis rod 411, a guide shell 412 on which the side scraping part 42 is slidably mounted, and a cyclone wheel 43. The guide shell 412 is symmetrically arranged on the outer surface of the central axis rod 411, and the guide shell 412 and the central axis rod 411 are integrally formed, and the cyclone wheel 43 is fixedly mounted on the lower end of the central axis rod 411. The structural setting of the rotating part 41 ensures that the guide shell 412 and the cyclone wheel 43 are installed on the central axis rod 411. The setting of the guide shell 412 facilitates the sliding installation and use of the side scraping part 42, and the setting of the cyclone wheel 43 facilitates the rotation of the central axis rod 411 when gas flows through.

[0025] Reference Figure 4 and Figure 5 As shown, the side scraper 42 includes a slide plate 421 and a triangular plate 422. The slide plate 421 is slidably mounted in the guide shell 412, and the triangular plate 422 is integrally formed and arranged at the outer end of the slide plate 421. The structural setting of the side scraper 42 ensures that the triangular plate 422 can be stably mounted in the guide shell 412 through the slide plate 421, and the pointed structure at the outer end of the triangular plate 422 makes it easier to scrape and clean the inner wall.

[0026] Reference Figure 3 and Figure 5As shown, the cyclone wheel 43 includes rotor blades 431 and an outer ring sleeve 432. The rotor blades 431 are evenly arranged on the inner side of the outer ring sleeve 432 along the circumferential direction, and the rotor blades 431 and the outer ring sleeve 432 are integrally formed. The structural setting of the cyclone wheel 43 ensures that a plurality of rotor blades 431 are stably arranged in the outer ring sleeve 432, so that when air is blown in, the gas flows through the rotor blades 431 to generate a rotational force, thereby driving the cyclone wheel 43 to rotate as a whole.

[0027] Reference Figure 3 and Figure 5 As shown, a positioning frame 31 for mounting the middle shaft rod 411 is provided in the air intake pipe 3, and mounting arc plates 301 are provided at both ends of the positioning frame 31, and the mounting arc plates 301 are integrally formed with the positioning frame 31. The positioning frame 31 includes a middle sleeve 311 and an outer plate 312, and the outer plate 312 is symmetrically arranged at both ends of the middle sleeve 311, and the outer plate 312 is fixedly connected to the middle sleeve 311. An auxiliary bearing 313 is installed in the middle sleeve 311, and the outer ring of the auxiliary bearing 313 is fixed to the middle sleeve 311, and the outer ring of the auxiliary bearing 313 is sleeved and fixed on the middle shaft rod 411. The auxiliary bearing 313 is installed in the middle sleeve 311 through the structural setting of the positioning frame 31, and then the middle axis rod 411 is inserted and installed in the auxiliary bearing 313, so that the middle axis rod 411 can be stably rotated and installed in the intake pipe 3. At the same time, by setting the installation arc plate 301 at the outer end of the outer plate 312, the positioning frame 31 can be stably fixed on the inner side of the intake pipe 3 through the arc plates 301 at both ends, so as to achieve stable installation and use.

[0028] Working principle: When needed, the air inlet pipe is connected to the external fan through a pipeline, so that when the fan is started, the air can be blown into the aerator shell through the air inlet pipe, and finally discharged into the sewage through the membrane cover. When the air continuously flows through the air inlet pipe, it can drive the cyclone wheel to rotate, and then the cyclone wheel can drive the rotating part and the side scraping part to rotate synchronously, ensuring that the side scraping part can scrape the inner wall of the air inlet pipe in real time during the ventilation process, which can effectively reduce the occurrence of impurities adhering to the inner wall of the air inlet pipe.

[0029] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes.
