Specifically, when the chemical raw material separation cavity separates the chemical raw material, the chemical raw material separation cavity can be sealed at this time, and the water pump 33 is started to perform negative pressure suction in the chemical raw material separation cavity, so that the solid-liquid separation speed of the chemical raw material can be accelerated, and the chemical liquid can permeate to the liquid collecting hopper 31 on the annular filter plate 21 and the conical filter cylinder 22, so that the chemical liquid is discharged and collected outwards by the water pump 33.

It should be noted that, when the flat pressing roller 54 rolls and removes the liquid from the solid matters on the annular filter plate 21, the horizontal scraping plate 92 pushes the solid matters on the annular filter plate 21 to achieve the turning effect, so that the flat pressing roller 54 rolls the solid matters more uniformly and thoroughly, and the liquid removal rate can be improved;
in addition, when the driving rod 4 drives the inclined outer plate 8 and the solid stripping component 9 to rotate, both can stir the chemical raw materials for solid-liquid separation in the chemical raw material separation cavity, and the stirring mode acts on the chemical raw materials for solid-liquid separation, so that the passing rate of the chemical raw materials on the basis of the solid-liquid separation component 2 can be quickened, and the solid-liquid separation efficiency of the chemical raw materials can be improved.

Specifically, when solid matters need to be removed, the material taking cover plate 102 on the solid plate 101 can be removed, the solid matters are pushed and scraped by the horizontal scraping plate 92 which moves annularly on the annular filter plate 21, so that the solid matters scraped by the inclined outer plate 8 on the conical filter cylinder 22 can be mixed into the solid matters on the annular filter plate 21, the solid matters on the annular filter plate 21 are pushed annularly together by the horizontal scraping plate 92 until the solid matters are positioned at the discharge hole, the discharging can be realized, and the technical problem that the solid matters separated by the solid matters and the liquid cannot be taken out from equipment quickly can be effectively solved, so that inconvenience is brought to the solid-liquid separation operation.
Referring to fig. 3, the liquid collecting hopper 31 is provided with an avoiding port for avoiding discharging materials at the position of the discharging port; thus, the scraped solid matters can be effectively discharged from the discharge hole.
Sealing valves are arranged on the feed pipe 13 and the collecting pipe 32; the design of the sealing valve on the feeding pipe 13 can be used for realizing sealing treatment on the chemical raw material separation cavity, namely, when the chemical raw material separation cavity is filled with chemical raw materials and needs to carry out solid-liquid separation operation, the feeding pipe 13 can be closed by the sealing valve, so that the efficiency and the solid-liquid separation quality of the chemical raw materials can be improved by the water pump 33 in a negative pressure suction mode conveniently, and the sealing valve on the collecting pipe 32 can be opened and closed for the corresponding water pump 33 to work.
