An inflammable and explosive dust absorption and dedusting system

Abstract

An inflammable and explosive dust absorption and dust removal system, including a dust suction cover set on the polishing grinding head and a PLC central control system that controls the operation of the entire system. The dust removal system has a reasonable structure design, small space occupation, and convenient installation and maintenance; The dust removal system effectively utilizes the Venturi effect. The Venturi tube is equipped with a water mist spray device, a water nozzle is installed behind the fan, and a water sprinkler is installed in the dust collection box to suppress and absorb sparks and dust generated by polishing at multiple levels, effectively Eliminate sparks and dust dispersion, high dust removal efficiency, and significantly improve the working environment. The dust removal system adopts a PLC integrated control system to realize online dynamic monitoring of sparks and dust concentration inside the air duct; the PLC control program realizes the safety interlock of the water sprinkler, fan, water nozzle, water mist injector and polishing grinding head. Avoid the risk of deflagration caused by grinding sparks and increased dust concentration when water sprinklers and water mist injectors are not turned on or malfunction due to human negligence.

Description

technical field [0001] The invention belongs to the dust removal technology in the field of mechanical processing and equipment, and in particular relates to a treatment system for inflammable and explosive metal dust. Background technique [0002] In the process of machining and manufacturing, when grinding and polishing the surface of raw materials or parts, a large amount of metal dust (such as titanium, aluminum magnesium, stainless steel, rust, etc.), dust, sand dust, and resin dust will be generated. , fiber dust, etc. When the combustible dust cannot be collected in time, handled or handled improperly, it will permeate the air and reach a certain dust concentration. If sparks or sparks are encountered, dust deflagration may occur. At the same time, it will cause the operators to face the occupational health and safety hazards of inhaling a large amount of dust. Existing vacuum dust collector technology, there are many types of dust collectors, often only focus on du...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide an inflammable and explosive dust absorption and dedusting system to solve the problems in the existing dust removal system that explosion accidents are easily induced due to the existence of sparks and the equipment cannot be automatically detected and prone to malfunctions that affect the dust removal effect.
