Medicine experiment filtering device for preventing medicine adhesion

Abstract

The invention discloses a medicine experiment filtering device capable of preventing medicine adhesion. The device comprises a filter box, a support plate and a base, wherein a coarse filter screen and a fine filter screen are fixed in the filter box in a horizontal state, cleaning push plates are arranged on the coarse filter screen and the fine filter screen, the cleaning push plates are connected with driving air cylinders installed on the outer wall of the filter box through piston rods, slag discharging openings are formed in the side walls of the ends, close to the coarse filter screen and the fine filter screen, of the filter box, a flushing pipe is hung on the top wall of the inner cavity of the filter box, and flushing spray heads distributed at equal intervals are arranged at thebottom of the flushing pipe. According to the invention, all the structures are matched with each other, so that medicine residues filtered out from the filter screen can be cleaned away in time, thesituation that the medicine residues are stuck to the filter screen due to long-term retention is avoided, the filter screen does not need to be removed from the filter box and then cleaned, the cleaning difficulty of the filter screen is lowered, and the filtering effect of the filter screen is guaranteed.

Description

technical field [0001] The invention relates to the technical field of filtering equipment, in particular to a filtering device for drug experiments that prevents drug adhesion. Background technique [0002] Before analyzing the composition of some medicinal liquids made of boiled Chinese herbal medicines and experimenting with their medicinal properties, it is necessary to use a filter device to filter the medicinal liquids to avoid the influence of fixed drug residues mixed in the medicinal liquids on the experiments. In the existing filter device, after filtering the liquid medicine, a large amount of drug residues will stay on the filter screen. If these drug residues are not cleaned from the filter screen in time, the drug residues will stick to the filter screen after staying for a long time, affecting the filtration. In order to improve the filtering effect of the net, it is necessary to manually remove the filter net from the filter box before cleaning, which is time...
