The stirring mechanism 4 is driven to stir and mix the raw materials in the barrel 3 to accelerate the dissolution rate of the raw materials. The bottom of the barrel 3 is connected with a first drug outlet pipe 6 and a second drug outlet pipe 7 which are symmetrically distributed. The outer sides of the first drug outlet pipe 6 and the second drug outlet pipe 7 are both installed with electric valves 8. The raw materials dissolved in the barrel 3 can be discharged into the first drug outlet pipe 6 or the second drug outlet pipe 7 through the driving of the electric valve 8. The outer sides of the bottom ends of the first drug outlet pipe 6 and the second drug outlet pipe 7 are both connected with a filter box 9 fixedly installed on the inner side of the support 1. The filter box 9 is provided with a filter plate 10 and an activated carbon plate 11.
