[0051] During operation, a worker throws wastewater into the mixing barrel 3 from the water inlet 31. After the wastewater is put in, the dosing mechanism 4, the stirring mechanism 5 and the scraping mechanism 7 are started. The medicine taking component 42 in the dosing mechanism 4 takes medicine from the medicine box 41. When the medicine in the medicine spoon 425 moves to the top of the water inlet 31, the dosing component 43 works to throw the medicine in the medicine spoon 425 into the mixing barrel 3 from the water inlet 31. When the amount of medicine put in reaches the required amount, the dosing mechanism 4 stops working. The stirring blades 55 in the stirring mechanism 5 stir during the process of dosing in the mixing barrel 3 of the dosing mechanism 4, so that the medicine can react with the wastewater faster. When the stirring is completed, the stirring mechanism 5 stops working. When the wastewater is stirred, it enters the filter box 6 from the first water outlet 32 ​​and flows out from the second water outlet 63. In the process of wastewater flowing out, the filter screen 61 will filter out impurities in the wastewater. The scraper 73 in the scraping mechanism 7 can scrape the impurities on the filter screen 61 and push them to the collection box 8. In the process of pushing them to the collection box 8, the baffle plate 742 in the baffle assembly 74 can ensure that the water inside the filter box 6 will not leak in the process of scraping the impurities into the collection box 8. Through the setting of the scraping mechanism 7, the movable scraper 73 in the scraping mechanism 7 can timely scrape the impurities on the filter screen 61 to avoid excessive impurities on the filter screen 61 affecting the filtering effect of the filter screen 61.

One end of the push rod 744 is connected to the scraper 73, and the other end of the push rod 744 can abut and cooperate with the spoiler plate 742.

[0055] When the scraper 73 moves, the scraper 73 drives the push rod 744 to move. When the push rod 744 touches the baffle plate 742, the push rod 744 pushes the baffle plate 742 out of the opening on the filter box 6. After the baffle plate 742 is pushed out by the push rod 744, the scraper 73 is just located in the opening on the filter box 6, thereby ensuring that waste water does not flow out of the opening on the filter box 6. The compression spring 743 can ensure that the baffle plate 742 can be reset in time when the scraper 73 is reset, thereby preventing waste water from flowing out of the opening on the filter box 6.

The medicine box 41 is arranged on the second bracket 2, and the medicine outlet of the medicine box 41 can cooperate with the medicine spoon 425.

[0059] When it is necessary to put medicine into the stirring barrel 3, the second rotating motor 421 is started to drive the first gear 422 to rotate, the rotation of the first gear 422 drives the second gear 423 to rotate, and the rotation of the second gear 423 drives the medicine spoon 425 to rotate. When the medicine spoon 425 moves below the medicine outlet of the medicine box 41, the medicine inside the medicine box 41 will fall into the medicine spoon 425. When the medicine spoon 425 is not below the medicine outlet of the medicine box 41, the top of the second gear 423 will block the medicine outlet of the medicine box 41 to prevent leakage of the medicine box 41. When the medicine spoon 425 that has taken the medicine moves to above the water inlet 31, the dosing mechanism 4 will drive the medicine box 41 to flip over and put the medicine into the stirring barrel 3.

[0060] Reference Figure 5 and Figure 6 As shown, the dosing assembly 43 includes a half-width gear 431 and a bevel gear 432. The half-width gear 431 is fixedly arranged on the base 424.
