Problems solved by technology

In the rolling process, the stability of the dust removal negative pressure is very high. The fluctuation of the negative pressure will directly reduce the stability of the weight of the cigarette and the stability of the suction resistance of the cigarette, which will affect the sensory quality of the cigarette, resulting in empty cigarettes and end wire

Abstract

The invention relates to an air supplement device of a flat-bag dust collector and an operating method for maintaining dedusting negative pressure stability, wherein the device and the operating method are applied to fields like tobacco and foodstuff and the like. The device comprises a programmable logic controller (PLC) (1), an electric control valve (21), a diaphragm valve (31), a cylinder (41), a silencer (51), and a negative pressure sensor (61). A filter bag back flushing signal by a flat-bag dust collector, the negative pressure sensor (61), and opening feedback signal of the electric control valve (21) are accessed to an input port of the PLC (1); and an output port of the PLC (1) is accessed to an opening setting signal of the electric control valve (21) and is connected with the diaphragm valve (31). According to the invention, advantages of simple structure, convenient implementation, low cost, substantial reduction of influence on negative pressures of a main tube by blow flushing and great market popularization value.

Description

technical field [0001] The invention relates to a supplementary air device of a flat-bag type dust collector applied in the fields of tobacco, food and the like, and an operation method for maintaining the stability of the negative pressure of dust removal. Background technique [0002] Flat bag filter is widely used in tobacco, food and other fields. Tobacco production enterprises adopt a centralized process wind dust removal system in the production process of coiling. Blow into the compressed air through the flat bag, so that the flat bag is rapidly inflated, shake off the soot accumulated on the flat bag, and then discharge it through the unloader. Since the negative pressure of the main pipe of the dust removal system is kept above -10000Pa, a large amount of compressed air is instantly introduced into the dust collector when the flat bag is blown back. In the rolling process, the stability of dust removal negative pressure is very high. The fluctuation of negative pr...
