Example Embodiment

[0062] Example 1

[0063] like figure 1 As shown, Embodiment 1 is a device for improving the purity of waste tobacco shredded tobacco, including:

[0064] Inlet shredded tobacco conveyor belt 2, outlet shredded tobacco conveyor belt 23, shredded tobacco thinning device 3, uphill variable frequency vibration transmission device 4, first electrostatic roller 7, second electrostatic roller 17, first synchronous toothed belt 6, second synchronous toothed Belt 16, first negative pressure shredding device 8, second negative pressure shredding device 18, first scraper 9, second scraper 19, positive pressure adjustable blowing device 14, negative pressure dust removal device 11, Downhill vibration transmission device 21, dust cover 5, heavy debris collection box 10, negative pressure dust removal gas pipe 12, positive pressure blowing gas pipe 13, gas distributor 20;

[0065] Wherein, the shredded tobacco thinning device 3 is arranged on the front end of the up-slope variable-freque...

Example Embodiment

[0079] Example 2

[0080] A multi-stage impurity removal method for waste tobacco cut tobacco. The waste tobacco cut tobacco mixture contains tobacco cut and non-tobacco sundries, the non-tobacco sundries include scraps of paper, dust and other sundries lighter than cut tobacco, and also includes tow, Metals, rubber blocks and other impurities heavier than shredded tobacco; the multi-stage impurity removal method is carried out using the device for improving the purity of waste tobacco shredded tobacco described in Example 1, including the following steps:

[0081] A. Thinning process of waste tobacco shredded tobacco

[0082] The waste tobacco shredded tobacco mixture is transported to the shredded tobacco thinning device 3 through the inlet tobacco shredded conveyor belt 2, and the shredded tobacco thinning device 3 acts smoothly and quickly to transition to the up-slope variable frequency vibration transmission device 4, so that the mixture of waste tobacco shredded tobacco...

Example Embodiment

[0091] Example 3

[0092] The experimental object is a waste cigarette processing line with a material flow rate of 2000kg / h in a cigarette production plant. The cigarette waste cigarettes are a certain thin cigarette with a processing capacity of 4000kg. The standard requirement for the purity of shredded tobacco for the recycled shredded tobacco is 99.90%. The waste tobacco treatment amount of the thin cigarettes of this specification is divided into two equal parts, and the waste tobacco cut tobacco is purified and impurity-removed by manual sorting and the impurity-removing method of Example 2 of the present invention.

[0093] Table 1 Comparative analysis of the results after manual sorting and the impurity removal treatment of Example 2 of the present invention

[0094]

[0095] As can be seen from Table 1, two kinds of impurity removal methods have no obvious influence on the cut tobacco quality index cut tobacco moisture content and the whole cut tobacco rate after...

Abstract

The invention belongs to the technical field of tobaccos, and particularly relates to a device for improving the purity of discard tobacco and a multi-stage impurity-removal method for the discard tobacco. The device comprises an inlet tobacco conveying belt (2), an outlet tobacco conveying belt (23), a tobacco spreading device (3), an uphill variable-frequency vibrating conveying device (4), a first electrostatic roller (7), a second electrostatic roller (17), a first negative-pressure shredded paper device (8), a second negative-pressure shredded paper device (18), a first scraper (9), a second scraper (19), a positive-pressure adjustable air-blow device (14), a negative-pressure dust removal device (11) and a downhill vibrating conveying device (21). By means of the device, three-stageimpurity-removal treatment of the discard tobacco is achieved; shredded paper scraps, tows and other impurities in the discard tobacco can be efficiently removed on the premise that the quality indexes, such as the water content of the tobacco and the tobacco structure, are basically unchanged; and the problems are solved that when the impurities are removed in the ways of hand picking, photoelectric dust removal and the like, the requirements for the quality of recycled tobacco are difficult to meet.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to a device for improving the purity of shredded waste tobacco and a multi-stage method for removing impurities from shredded waste tobacco. Background technique [0002] During the cigarette rolling process, due to various reasons, there will be some defective cigarettes that do not meet the product quality requirements, that is, waste cigarettes. Due to the high recycling value of shredded tobacco in waste cigarettes, cigarette manufacturers generally collect waste cigarettes and separate the shredded tobacco from waste cigarettes on the waste smoke treatment line for recycling, while waste paper and waste filters Other auxiliary materials with low utilization value are sent to the waste recycling station. [0003] The traditional waste tobacco treatment methods mainly include rod beating and cutting, but both of them inevitably cause the shredded tobacco to contain r...
