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.
