[0020] When in use, the water inlet end of the water pump 2 is connected to the previous process device of sewage treatment, and the water outlet pipe 9 is connected to the next process device of sewage treatment. By setting the quantitative mechanism 7, the electric telescopic rod 702 is started to control the height of the quantitative plate 703 in the quantitative cylinder 701, so that the volume of the weighing cavity in the quantitative cylinder 701 meets the volume of the required pharmaceutical powder. After the quantitative cylinder 701 is full, the quantitative plate 703 is controlled to descend by the electric telescopic rod 702 until the guide block 710 extends from the bottom of the quantitative cylinder 701, and then the powder is evenly scattered on the surface of the impeller 10 through the guide block 710. The water pump 2 continuously pumps the sewage after impurities removal to the surface of the impeller 10 to drive the impeller 10 to rotate, and at the same time, the powder is quickly dissolved under the impact of the sewage, thereby improving the adequacy of the powder dissolution. By setting the impeller 10 and the metering cylinder 701 to be fixedly connected, as the impeller 10 rotates, the metering cylinder 701 is driven to rotate synchronously through the connecting shaft 707, and the steel balls 705 inside the metering cylinder 701 roll irregularly in the metering cylinder 701, so that the agglomerated powder is fully crushed, and a plurality of convex strips 704 are provided to block the steel balls 705, so that the steel balls 705 intermittently hit the metering plate 703 during the rolling process, so that the powder can pass through the filter holes of the metering plate 703 more smoothly, and then enter the mixing cylinder 1, thereby improving the utilization rate of the powder.

[0021] In this embodiment, a servo motor 4 and a controller 5 are fixedly installed on the top of the chemical powder barrel 3, and a second stirring mechanism 14 is provided in the chemical powder barrel 3. The second stirring mechanism 14 is used to assist the powder to flow downward and smooth the top of the powder, so as to facilitate observation of the precise remaining amount of the powder. The second stirring mechanism 14 includes a second main shaft 1401, which is rotatably installed in the chemical powder barrel 3 and the bottom end of the second main shaft 1401 passes through the first blocking block 16 and is fixedly installed with the top rotation center of the unloading switch 15. A plurality of second stirring shafts 1402 adapted to the inner wall of the chemical powder barrel 3 are fixedly installed near the bottom surface of the second main shaft 1401. A retaining ring 1409 is fixedly sleeved on the surface of the shaft 1401, two limiting convex rafters 1403 are provided on the surface of the second main shaft 1401, a counterweight block 1405 is slidably sleeved on the surface of the second main shaft 1401, a sliding groove matching the limiting convex rafter 1403 is provided on the inner ring surface of the counterweight block 1405, a second scraper 1404 is fixedly installed on one side of the counterweight block 1405, a fourth groove is provided on the top of the counterweight block 1405, a magnet 1406 is fixedly installed in the fourth groove, a sealing cover 1407 matching the fourth groove is fixedly installed on the surface of the magnet 1406, and an electromagnetic device 1408 is fixedly installed on the top of the chemical powder tube 3.

[0022] When in use, the controller 5 is provided with a PLC control system for controlling the operation of the servo motor 4, the electric telescopic rod 702 and the electromagnetic device 1408.

As the second main shaft 1401 rotates, it drives the multiple second stirring shafts 1402 to stir the powder, making the unloading smoother. At the same time, the second scraper 1404 arranged on the top of the powder moves along with the second main shaft 140 1 rotates, and slides downward along the second main shaft 1401 as the powder is lowered, thereby smoothing the top of the powder. The surface of the second scraper 1404 is arranged to be uneven so that a greater friction is formed between it and the powder, thereby preventing the second scraper 1404 from being buried in the powder, making it easier for the staff to clearly observe the remaining amount of the powder, thereby improving the convenience of using the equipment. When loading the powder, the electromagnetic device 1408 is first started to generate suction to the magnet 1406, thereby bringing the second scraper 1404 to the top of the chemical powder tube 3, thereby preventing the powder from burying it.

[0023] In this embodiment, a first stirring mechanism 12 is provided in the mixing barrel 1, and the first stirring mechanism 12 includes a first main shaft 1201 and two first scrapers 1203.

A plurality of through holes for filtering solid reactants are opened at the bottom of the filter box 11, and the bottom of the filter box 11 is flush with the top of the cleaning block 17.

[0024] When in use, by setting up the first stirring mechanism 12, solid reactants will be produced as the chemical reaction between the medicine powder and the sewage occurs. The filter box 11 can be set to isolate the solid reactants in the mixing barrel 1 to prevent them from entering the next process. The impurities accumulated on the inner wall of the mixing barrel 1 can be scraped off by the first scraper 1203 and dropped into the slag collecting box 8 below, which is convenient for centralized processing later. As the first scraper 1203 rotates, it can also drive the cleaning block 17 to clean the impurities accumulated at the bottom of the filter box 11 to keep it unobstructed, and as the first stirring mechanism 12 operates, the reaction between the medicine powder and the sewage can be further accelerated.

It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
