Impurity and dust removal device for front and back surfaces of waste tobacco shreds and impurity and dust removal method thereof

Abstract

The invention belongs to the technical field of tobacco processing, and discloses an impurity and dust removal device for front and back surfaces of waste tobacco shreds and an impurity and dust removal method thereof. The device comprises a front-section variable-frequency vibration conveying device, a rear-section variable-frequency vibration conveying device, an electrostatic plate I, a conveying belt I, a baffle, an electrostatic plate II, a conveying belt II, an electrostatic emitter I, an electrostatic emitter II, an electrostatic sending machine I and an electrostatic sending machine II. The front-section variable-frequency vibration conveying device and the rear-section variable-frequency vibration conveying device are arranged front and back through a rack. The electrostatic plateI and the electrostatic plate II are placed on the conveying belt I and the conveying belt II respectively. Based on an electrostatic adsorption impurity removal principle, the electrostatic plates are adopted to adsorb impurities and flying dust in the front face and the back face of the incoming waste tobacco shreds, under the condition that physical quality indexes of the tobacco shreds are kept unchanged as much as possible, the impurities, tobacco powder and the flying dust in the waste tobacco shreds can be thoroughly removed, the purity of the recycled tobacco shreds is improved, the use value of waste tobacco shred recycling is effectively improved, and economic benefits of enterprises are enhanced.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a device for removing impurities and dust from the front and back sides of waste tobacco cut tobacco and a method for removing impurities and dust. Background technique [0002] In the process of cigarette waste treatment, cigarette auxiliary materials such as cigarette paper and tow are inevitably shredded and mixed into recycled shredded tobacco, which are regarded as sundries; similarly, shredded tobacco will also be shredded, resulting in less than 1.0 mm also contains more tobacco powder or fly ash; therefore, the shredded tobacco obtained after waste smoke treatment needs to remove impurities and fly ash before it can be further blended into normal shredded tobacco for use. [0003] At present, domestic tobacco companies mainly use manual picking or image recognition-based photoelectric impurity removal and vibration screening and dust removal methods...

AI Technical Summary

Problems solved by technology

However, it is difficult to completely pick out the shredded paper scraps and other sundries in shredded tobacco by manual picking and removing impurities, and the picking quality is difficult to guarantee. At the same time, there are defects such as labor-intensive and high labor intensity; there are false pickings by using photoelectric impurity removal methods, It is often necessary to sacrifice a certain proportion of shredded tobacco to ensure the removal rate of debris, which in turn affects the yield of shredded tobacco; the use of vibration screening to remove tobacco dust or fly ash has the disadvantages of affecting the processing environment and shredded tobacco again, which affects the yield of shredded tobacco. risk
