Mining modularized dry-type dedusting system and dedusting method

Abstract

A mining modularized dry-type dedusting system and a dedusting method are used for dedusting of underground fully-mechanized roadway heading faces. The system comprises a filter tank, a pneumatic blowing device, a soft metal filter device and an automatic ash discharging device, and the pneumatic blowing device, the soft metal filter device and the automatic ash discharging device are arranged onthe upper portion, the inner portion and the bottom portion of the filter tank sequentially. The soft metal filter device is arranged in the filter tank and is a soft metal filter bag. The pneumatic blowing device is connected with a knocking hammer, the automatic ash discharging device is arranged on the lower portion of the filter tank and is a 35-degree inverted conical steel plate, and the knocking hammer is mounted on the left side of the inverted conical steel plate. When the system is in operation, dusty air is filtered through the soft metal filter device in the filter tank, and the pneumatic blowing device on the upper portion of the filter tank starts blowing to clean the soft metal filter device while the automatic ash discharging device at the bottom of the filter tank starts discharging ash. The mining modularized dry-type dedusting system and the dedusting method have advantages that great dedusting effects and convenience in ash discharging are realized, and the problemof bag sticking in conventional dry-type dedusting is avoided.

Description

technical field [0001] The invention is used for dust removal on fully mechanized excavation working faces in coal mines, and in particular relates to a modular dry dust removal system for mines, which belongs to the technical field of roadway ventilation and safety. Background technique [0002] With the improvement of the degree of mechanization of the roadway and the use of high-efficiency and high-power roadheaders, conveyors and local ventilation equipment, the dust sources and the amount of dust produced in the fully mechanized roadway have increased, resulting in a significant increase in the dust concentration in the air in the roadway. Even seriously exceeding the standard, these high-concentration and high-dispersion dust seriously affect the working environment of the roadway and endanger the health of workers. The main dust sources in the tunneling roadway include the tunneling face, the transfer points of the transportation equipment, and the secondary dust gene...

AI Technical Summary

Problems solved by technology

For this reason, engineers and technicians in this field have done a lot of research on the dust removal equipment of fully mechanized excavation working face, and developed dry dust removal equipment; The problem of filter paste bags and equipment cleaning of dry dust removal equipment is time-consuming and laborious, which leads to restrictions in the promotion and application of dry dust removal equipment
