[0027] The entire device is supported by installing the support column 1, and the motor 5 is installed to provide power for the operation of the entire device.

[0028] In order to achieve the purpose of injecting sewage into the device and filtering the sewage for the first time, Figure 2 As shown, the filter group 7 includes a three-way pipe 71, and a filter auger 2 72 is rotatably connected to the middle part of the inner cavity of the three-way pipe 71. The upper end of the filter auger 2 72 passes through the middle part of the top wall and the middle part of the upper end of the inner cavity of the three-way pipe 71 in sequence and is fixedly connected to a transmission wheel 3 73. The inner cavity of the transmission wheel 3 73 is wound and connected to the right part of the inner surface of the belt 1 6.

[0029] It should be particularly noted that a number of holes are provided on the filtering auger 2 72. First, by starting the motor 5, with the cooperation of the stirring mechanism 4, the belt 1 6 is driven to rotate. The belt 1 6 rotates, driving the transmission wheel 3 73 to rotate.

The larger sediment or garbage in the sewage is transmitted to the upper part of the three-way pipe 71 by the filtering auger 2 72 and discharged from the front end, thereby achieving the purpose of injecting the sewage into the interior of the device and filtering the sewage for the first time.

[0030] In order to achieve the purpose of further treating sewage and automatically discharging sediment, such as Figure 3 As shown, the sewage treatment tank 2 includes a tank body 21, and a sludge discharge groove 22 is provided at the front of the inner cavity and the front of the upper end of the tank body 21.

The upper end of the filter auger 23 passes through the top wall of the inner cavity of the sludge discharge groove 22 and the front of the upper end of the tank body 21 in sequence and is fixedly connected to a transmission wheel 25. A sludge discharge pipe 24 is fixedly connected to the right front end of the tank body 21, and the inner cavity of the sludge discharge pipe 24 is communicated with the upper part of the inner cavity of the sludge discharge groove 22. A dosing port 26 is fixedly connected to the left part of the upper end of the tank body 21. The four corners of the lower end of the tank body 21 are respectively fixedly connected to the upper ends of four support columns 1 in the vertical direction. The upper right part of the tank body 21 is fixedly connected to the left end of the three-way pipe 71. The middle part of the upper end of the tank body 21 is fixedly connected to the lower end of the motor 5. The inner cavity of the transmission wheel 25 is wound and connected to the right part of the inner surface of the belt 28. The middle part of the lower end of the tank body 21 is fixedly connected to the upper end of the sewage treatment tank 2.

[0031] First, the sewage enters the tank body 21 through the filter group 7, and a proper amount of medicine is added through the dosing port 26. The motor 5 is started and the sewage and the medicine are fully reacted with the cooperation of the stirring mechanism 4 to produce precipitation. The precipitation enters the lower part of the inner cavity of the silt discharge trough 22 with the cooperation of the stirring mechanism 4. At the same time, the transmission wheel 25 is driven by the belt 28 to rotate, and then the filtering auger 23 is rotated in the inner cavity of the silt discharge trough 22, so that the precipitation in the lower part of the inner cavity of the silt discharge trough 22 is transmitted to the upper part of the silt discharge trough 22 by the filtering auger 23 and discharged through the silt discharge pipe 24, thereby achieving the purpose of further treating the sewage and automatically discharging the precipitation.

[0032] In order to achieve the purpose of making the sewage react with the reagent quickly and removing the stains remaining on the inner wall of the tank body 21, as Figure 4 As shown, the stirring mechanism 4 includes a roller 42, two transmission wheels 41 are fixedly connected to the upper portion of the outer surface of the roller 42, a wall scraper 43 is fixedly connected to the middle portion of the outer surface of the roller 42, a filter group 44 is slidably connected to the inner cavity of the roller 42, the upper end of the roller 42 is fixedly connected to the output end of the motor 5, the upper portion of the outer surface of the roller 42 is rotatably connected to the upper portion of the inner cavity of the tank body 21, the inner cavity of the upper transmission wheel 41 is wound and connected to the left portion of the inner surface of the belt 1 6, and the inner cavity of the lower transmission wheel 41 is wound and connected to the left portion of the inner surface of the belt 2 8.

[0033] First, by starting the motor 5, the motor 5 drives the roller 42 to rotate, and drives the two driving wheels 41 to rotate at the same time, and the two driving wheels 41 cooperate with the belt 1 6 and the belt 2 8 to drive the filter group 1 7 and the belt 2 8 to work at the same time, which plays a role in energy saving. The roller 42 rotates and drives the wall scraper 43 to stir the sewage and the agent, accelerate the reaction of the sewage and the agent, and at the same time scrape off the stains remaining on the inner wall of the tank body 21, and pass through the filter group 2 44 to make the generated precipitate enter the silt discharge trough 22 and finally be discharged, thereby achieving the purpose of making the sewage and the agent react quickly and removing the stains remaining on the inner wall of the tank body 21.

[0034] Further explanation, such as Figure 5 As shown, the filter group 2 44 includes a connecting block 441, the lower end of the connecting block 441 is fixedly connected to an arc scraper 442, the inner cavity of the arc scraper 442 is slidably connected to an arc filter cover 443, the lower part of the outer surface of the arc filter cover 443 is fixedly connected to the middle part of the oblique cone surface of the inner cavity of the tank body 21, and the outer surface of the connecting block 441 is slidably connected to the inner cavity of the roller 42.

[0035] The first produced sediment is retained on the upper surface by the arc-shaped filter cover 443, and the treated water flows into the bottom of the inner cavity of the tank body 21 through the arc-shaped filter cover 443 and is discharged through the drain pipe 3. The roller 42 rotates, and with the cooperation of the connecting block 441, the arc-shaped scraper 442 rotates on the upper part of the outer surface of the arc-shaped filter cover 443 and scrapes off the sediment thereon, and discharges it into the lower part of the inner cavity of the silt discharge trough 22, thereby achieving the purpose of assisting the sewage treatment tank 2 to discharge the sediment.

[0036] The working principle of the utility model is as follows: first, the motor 5 is started to rotate through the stirring mechanism 4, and the driving wheel 3 73 and the driving wheel 1 25 are driven to rotate respectively through the belt 1 6 and the belt 2 8, and then the sewage is injected through the right end of the three-way pipe 71, and the sewage passes through the holes on the filtering auger 2 72 and enters the inner cavity of the tank body 21 from the outlet at the left end of the three-way pipe 71. The larger sediment or garbage in the sewage is transmitted to the upper part of the three-way pipe 71 by the filtering auger 2 72 and discharged from the front end, and an appropriate amount of medicine is added through the dosing port 26, and the wall scraper 43 is driven by the rotation of the roller 42 to stir the sewage and the medicine, so as to accelerate the reaction of the sewage and the medicine and at the same time clean the tank body 21. The stains remaining on the inner wall are scraped off, and the resulting sediment is retained on the upper surface by the arc-shaped filter cover 443. The treated water flows into the bottom of the inner cavity of the tank body 21 through the arc-shaped filter cover 443 and is discharged through the drain pipe 3. The roller 42 rotates, and with the cooperation of the connecting block 441, the arc-shaped scraper 442 rotates on the upper part of the outer surface of the arc-shaped filter cover 443 and scrapes off the sediment thereon, and discharges it into the lower part of the inner cavity of the silt discharge trough 22. At the same time, the transmission wheel 25 is rotated, thereby rotating the filter auger 23 in the inner cavity of the silt discharge trough 22, so that the sediment in the lower part of the inner cavity of the silt discharge trough 22 is transmitted to the upper part of the silt discharge trough 22 by the filter auger 23 and discharged through the silt discharge pipe 24.
