Abstract

The invention relates to a tobacco stem screening tube which is characterized by consisting of a screening tube device, a transmission device and a dust removing mechanism. The screening tube device essentially consists of a screening tube body, a rolling ring on the tube body, a sealing housing and a discharging port and a feeding cover and a discharging cover at two ends of the tube body; the screening tube body is welded by a feeding port section, a tobacco dust screen tube section, a short stem screen tube body, a middle and long stem screen tube body and a stem head outlet tube section. The dust removing system consists of a dedusting fan and a dedusting pipe that are installed on the feeding cover. The invention optimizes the stem screening technique and is integrated with stem screening and dust removing, thus solving the problems of poor screening effect and product quality resulting from manual screen cleaning due to screen blockage by tobacco stem, ensuring good product quality, preventing dust from flying through dust collecting, maintaining cleanness of the on-site production environment and saving energy and equipment occupation area as a plurality of original devices are integrated into one device.

Description

Technical field [0001] The invention relates to a tobacco stalk screening and dust removal equipment for a threshing and redrying line in the tobacco industry, in particular to a tobacco stalk screening drum. Background technique [0002] In the tobacco industry threshing and redrying line tobacco stem processing and production process, the tobacco foam and stem heads in the tobacco stems need to be screened out, and short-stem, medium-stem and long-stem products are screened out and packaged separately. At present, most of the tobacco stem screening processes used online use a stem head vibrating screening machine and a tobacco foam, short stem, medium stem, and long stem vibrating screening machine. On the one hand, it is easy to cause blockage of the screen mesh and must be carried out by a dedicated person. On-site manual screen surface cleaning, and after cleaning the screen surface for many times, it is easy to cause deformation of the screen surface, which seriously affect...

AI Technical Summary

Problems solved by technology

Most of the tobacco stem screening processes currently used online use a stem head vibrating screening machine and a smoke, short stem, medium stem, and long stem vibrating screening machine. On the one hand, it is easy to cause blockage of the screen holes, and special personnel must be appointed On-site manual cleaning of the screen surface, and after cleaning the screen surface many times, it is easy to cause deformation of the screen surface, which seriously affects the screening effect and cannot guarantee product quality; The site is dusty and the production environment is poor
