[0020] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] like Figure 1-3As shown, the utility model provides an underground sewage purification and circulation treatment device, including a sewage filter tank 1, a first filter screen 2 is provided inside the sewage filter tank 1, and a rotating block 3 is rotatably installed at the center, a plurality of scraping strips 4 are evenly provided on the top of the rotating block 3, and the scraping strips 4 are in contact with the surface of the first filter screen 2. When the rotating block rotates, it can drive each scraping strip 4 to rotate, and the scraping strips 4 can scrape off the debris generated by flocculation on the surface of the filter screen, thereby preventing the debris from sticking to the first filter screen 2. A first sewage pipe 5 is provided at the top of one side, a second sewage pipe 6 is provided at the top of one side of the first sewage pipe 5, and the other end of the second sewage pipe 6 passes through the surface of the sewage filter tank 1, and a rotating shaft 7 is provided on the top of the rotating block 3. The top end of the rotating shaft 7 passes into the first sewage pipe 5, and an auger blade 8 is provided on the surface of the rotating shaft 7. When the auger blade 8 rotates, the debris on the top of the filter screen can be twisted into the first sewage pipe 5, and after moving to the top inside the first sewage pipe 5, it enters the second sewage pipe 6 for discharge.

[0022] Among them, a motor 9 is fixedly installed on the top of the sewage filter tank 1, and the output end of the motor 9 is connected to the rotating shaft 7 through a coupling. The motor 9 can drive the rotating shaft 7 to rotate through the coupling, thereby rotating the rotating block and the auger blade 8.

[0023] Among them, the first filter screen 2 is funnel-shaped as a whole, and the center is concave. The flocculated debris intercepted by the first filter screen 2 will move toward the center of the first filter screen 2 under the action of the funnel-shaped first filter screen 2, and will be twisted by the auger blades 8 on the surface of the rotating shaft 7 located at the center of the filter screen to be discharged into the first sewage pipe 5.

[0024] Among them, the surface array of the first sewage pipe 5 is provided with a plurality of drainage grooves 10, and the inner side of each drainage groove 10 is provided with a second filter screen 11. In the process of discharging flocculated impurities from the first sewage pipe 5, the water contained therein can return to the sewage treatment tank through the drainage groove 10, and the impurities are blocked in the first sewage pipe 5 by the provided second filter screen 11.

[0025] A water inlet pipe 12 is provided at the top of one side of the sewage filter tank 1 , and a drain pipe 13 is provided at the bottom of the sewage filter tank 1 . The drain pipe 13 is used to discharge the filtered clean water.

[0026] The bottom of the sewage filter tank 1 is evenly provided with support legs 14 , which play a role of fixing and supporting the sewage filter tank 1 .

[0027] Specific working principle:

[0028] Before using the present invention, first connect the present invention to an external power supply and a control panel, and control the operation of the present invention through the external control panel. During the use of the present invention, the flocculated sewage enters the sewage filter tank 1 of the present invention from the water inlet, is filtered by the first filter screen 2, and is discharged from the drain pipe 13. During this process, the first filter screen 2 will intercept the flocculated impurities at its top, and under the action of the funnel-shaped first filter screen 2, it slides to its center. During this process, the motor 9 drives the rotating shaft 7 to rotate, and the auger blades on the surface of the rotating shaft 7 are driven by the motor 9 to rotate. The blade 8 twists the impurities near it into the first sewage pipe 5, and under the transportation of the auger blade 8, the impurities entering the first sewage pipe 5 move to the second sewage pipe 6 and are discharged from the second sewage pipe 6, thereby reducing the probability of impurities accumulating on the top of the first filter screen 2 and causing blockage of the first filter screen 2. At the same time, during the rotation of the rotating shaft 7, the rotating block 3 will be driven to rotate, and the rotating block 3 will drive each scraper 4 to rotate. The scraper bars 4 scrape the impurities on the surface of the filter screen, so that it can approach the auger blade 8 faster, thereby improving the efficiency of impurity cleaning.
