A screening and dust removal machine

Abstract

The present application relates to the technical field of herbal dedusting, in particular to a drug screening and dedusting machine. The main points of the technical solution are as follows: including a dedusting screen cylinder and a dedusting box sleeved on the outside of the dedusting screen cylinder; The first dust removal pipe is connected internally, and the first dust removal pipe is connected with a cyclone separator; the air outlet end of the cyclone separator is connected with a second dust removal pipe; the air outlet end of the second dust removal pipe is provided with a sealed purification box, and the second dust removal pipe runs through The side wall of the purification box extends toward the interior of the purification box; the second dust removal pipe is provided with a purification bag that communicates with the inside of the second dust removal pipe, and the purification bag can pass air and prevent dust from passing through; It achieves the purpose of further purifying and dedusting the air output by the cyclone separator, so as to further reduce the dust impurities in the air and reduce the harm to the health of workers.

Description

technical field [0001] The present application relates to the technical field of herbal dedusting, in particular to a drug screening and dedusting machine. Background technique [0002] There are still a lot of dust impurities in Chinese herbal medicines after drying, which requires dust removal and filtration of Chinese herbal medicines. [0003] Authorized announcement number CN205816160U discloses a drum drug screening machine, which includes a frame and a drum with openings at both ends; the drum body is surrounded by a screen, and the drum can rotate in a fixed axis inside the frame; the drum is connected with a dust channel , the dust channel is connected with a cyclone separator; a fan is connected between the dust channel and the cyclone separator; the dust raised inside the drum enters the cyclone separator through the dust channel under the action of the fan, and under the action of the cyclone separator, large Part of the dust is separated from the air, and relat...
