Comprehensive impurity eliminating and screening equipment for tobacco stems

Abstract

The invention discloses comprehensive impurity eliminating and screening equipment for tobacco stems. An electromagnetic roller type eliminator is arranged below a discharge end of a belt conveyor, and is formed by arranging an electromagnetic roller wrapped with a felt on a speed-adjustable driving motor; a cleaning brush is arranged on a lower part of the electromagnetic roller wrapped with thefelt and is in contact with the electromagnetic roller; an air suction inlet of a dust collection device has an arc shape similar to the electromagnetic roller, and is arranged laterally above the electromagnetic roller wrapped with the felt; an air outlet of the dust collection device is connected with a dust collection air suction pipeline; a collection box used for collecting impurities of which the specific gravity is greater than that of the tobacco stems is arranged below the inner side of a discharge port of the dust collection device; a screening machine is arranged below the outer side of a discharge port of a dust collection box device; and a front part of a screening frame of the screening machine is provided with a screen mesh used for eliminating short stems, and a rear part of the screening frame is provided with stainless steel tubes equidistantly arranged for eliminating stalks and stumps. The comprehensive impurity eliminating and screening equipment has the characteristics of elimination of various impurities, high elimination efficiency and simple equipment structure.

Description

technical field [0001] The invention relates to a screening device for the tobacco industry, in particular to a multifunctional tobacco stem screening device for removing magnetic metal impurities, particles with a large specific gravity, hair dust with a small specific gravity, special-shaped tobacco crutches and mushroom heads. Background technique [0002] At present, in the tobacco industry, tobacco stems are one of the important raw materials for cigarette production and processing. The tobacco stems used by cigarette companies come from various tobacco leaf bases, and the quality, specifications and purity of the tobacco stems after threshing and redrying are all different. Therefore, the tobacco stems put into production by the enterprise's silk thread contain more debris (such as hair, rubber strips / blocks, hemp silk, magnetic metal debris, particles with larger specific gravity, etc.), special-shaped mushroom heads and Tobacco crutches, short stems, and tobacco dus...

AI Technical Summary

Problems solved by technology

Therefore, the tobacco stems put into production by the enterprise's silk thread contain more debris (such as hair, rubber strips / blocks, hemp silk, magnetic metal debris, particles with larger specific gravity, etc.), special-shaped mushroom heads and Tobacco crutches, short stems, and tobacco dust, these substances will not only damage the equipment such as stem pressing and cutting, but also have a negative impact on product quality, especially rubber strips / blocks and other rubber debris mixed into the next process , will have a serious impact on product quality

Therefore, there are impurity removal and screening devices designed on the silk-making lines of cigarette enterprises to ensure the quality and purity of tobacco stems during processing. However, the existing screening and impurity removal equipment has a single function and requires more equipment in series to Realize the elimination of various sundries and the screening of short-stem tobacco powder, resulting in longer processing flow, complicated equipment and low production efficiency
