Station self-control dust removal system

Abstract

A station self-control dust removal system comprises a fan, a dust collector, a main vent line, branch vent lines, exhaust hoods, air valves, Hall switches and magnets; the dust collector is connectedbetween the fan and the main vent line, and one branch vent line is arranged between the main vent line and each station; the end of each branch vent line is provided with one exhaust hood, and the air valves are arranged between the ends of the branch vent lines and the exhaust hoods; the magnets are fixedly installed on valve plates of the air valves, and the Hall switches are installed on casings of the air valves, and matched with the magnets; when the air valves are closed, the magnets are adjacent and opposite to the Hall switches; when the air valves are opened, the magnets are separated from the Hall switches; the start-stop of the fan is controlled through a PLC; when the air valves of all stations are in the closed state, the fan is in a shutdown state; when the air valves of all the stations are in the open state, the fan runs with the maximum operating power; when the fan is started, the fan operating power is in direct proportion to the number of the air valves opened.

Description

technical field [0001] The invention belongs to the technical field of industrial dust removal equipment, in particular to a station self-control dust removal system. Background technique [0002] At present, in metallurgical forging, mechanical processing, light industrial production and other industries, it is common to encounter different degrees of dust pollution during the production stage, and the dust generated during the production stage will directly threaten human health. When the dust falls into the rotating parts of the production equipment On the other hand, it will accelerate the wear of rotating parts, thereby reducing the operating accuracy and service life of production equipment. In addition, when the dust permeates the production workshop, it will first reduce the visibility, which will not only affect the workers' vision, but also hinder the workers' operation, thereby reducing labor productivity, and even lead to safety accidents in severe cases.

AI Technical Summary

Problems solved by technology

[0002] At present, in metallurgical forging, mechanical processing, light industrial production and other industries, it is common to encounter different degrees of dust pollution during the production stage, and the dust generated during the production stage will directly threaten human health. When the dust falls into the rotating parts of the production equipment On the other hand, it will accelerate the wear of rotating parts, thereby reducing the operating accuracy and service life of production equipment

In addition, when the dust permeates the production workshop, it will first reduce the visibility, which will not only affect the workers' vision, but also hinder the workers' operation, thereby reducing labor productivity, and even lead to safety accidents in severe cases.

[0003] Therefore, in order to avoid a series of disadvantages caused by dust pollution, manufacturers generally configure corresponding dust removal systems for production workshops. According to different dust removal principles, they can be divided into electrostatic type, cyclone type, spray type and bag type, etc. But no matter what kind of dust removal principle the dust removal system adopts, it belongs to the centralized dust removal system, which leads to the characteristics of bulky dust removal system, complicated assembly of dust removal equipment, poor installation flexibility, high operating power and high operating cost. The centralized dust removal system is more suitable for large and medium-sized enterprises, but for those small and micro enterprises, it is difficult to bear in terms of equipment purchase cost and operating cost

Since small and micro enterprises usually have the characteristics of scattered dust emission stations and unbalanced dust emission at each station, when the central centralized dust removal system faces the above situation, the waste of funds and energy will be very serious, so it is necessary to design A brand-new dust removal system to meet the dust control needs of small and micro enterprises
