Anti-blocking suction device of winnowing and impurity removal equipment of stem screening line

Abstract

The invention provides an anti-blocking suction device of winnowing and impurity removing equipment of a stem screening line. The anti-blocking suction device comprises an impurity removal fan, a nylon-net cut-stem conveying line, a wind power circulation loop, a nylon-net impurity conveying belt, a blowing fan, a roller brush, an impurity discharging channel and an impurity collecting cloth bag;an observation window is formed in the lower part of a fan box body of the impurity removal fan; a material guide plate for obliquely collecting materials is mounted at the bottom in the fan box body;a cut stem suction cover is arranged above the lowest part of the material guide plate; the cut stem suction cover communicates with the tail end of a pipe opening of a dust suction pipe, extending into the fan box body, of a dust collector through a 90-degree elbow; and the dust collector is arranged on the outer side of the fan box body and is connected with a platform frame body of the fan boxbody into a whole. According to the device, the problems of cut stem accumulation blockage and suction discharging in the fan box body are effectively solved; the device is simple in structure, easyto implement, reliable in sealing and convenient to disassemble; cut stems accumulated in the box body can be subjected to suction discharging in a centralized and timely manner; and the device is economical, practical, labor-saving, efficient and reliable.

Description

technical field [0001] The invention belongs to the technical field of tobacco stem removal and manufacture, and in particular relates to an anti-blocking suction device for air separation and impurity removal equipment for sieve stem lines. Background technique [0002] Baoji Cigarette Factory Logistics Sub-Centre Bayu Reservoir Area Screening Line Equipment was officially put into operation in January 2019. Among them, the air separation and impurity removal process section of the screening line is the key link of the entire screening line equipment. Regarding the main structure of the air separation and impurity removal equipment for the sieve line, (such as figure 1 Shown) is to install a 18KW high-power impurity removal fan 1 at the bottom of the impurity removal equipment, which is connected with the air inlet and outlet of the impurity removal fan 1, and establishes an independent closed upward suction for the nylon mesh stem wire conveying line 2 The air circulation...
