Matched high-pressure spraying box based on coal mining equipment

Abstract

The invention relates to the technical field of coal mining and discloses a matched high-pressure spraying box based on the coal mining equipment. The matched high-pressure spraying box comprises a base, wherein a connecting rod is fixedly mounted on the upper surface of the base; a water storage disc is fixedly mounted on the upper surface of the connecting rod; an electrochemical plate is fixedly embedded in the water storage disc; a fixed block is fixedly mounted in the base; a water pumping device is fixedly mounted on the left side of the fixed block; a turbine is movably installed in thefixed block; a measuring rod is slidably installed at the right side of the fixed block; a water passing pipe is fixedly installed on the upper surface of the fixed block; a water controlling plate is slidably installed in the electrochemical plate; a baffle is slidably installed at the inner right side of the electrochemical plate; and a connecting block is fixedly installed at the left side ofthe baffle. Through cooperative use of the fixed block, the water pumping device, the turbine and the measuring rod, impurities in water can be removed; so the impurities in the water are prevented from blocking the water passing pipe, and the use of the matched high-pressure spraying box is facilitated.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a matching high-pressure spray box based on coal mining equipment. Background technique [0002] The mining of mineral resources is the main way for human beings to obtain energy, and the mining industry is also one of the important raw material industries. Among them, the mining of coal mines is a traditional way of obtaining energy. One of the equipment, the coal shearer is generally composed of a cutting part, a loading part, a traveling part, an electric motor, an operation control system and auxiliary devices. [0003] At present, the main technical way of dust prevention when shearer is cutting coal is to use the low-pressure internal and external spray dust suppression system of the shearer. The principle of dust reduction is to impact the dust-producing space of the pick with mist-like pressure water jets, wet the coal body with atomized water, and capture flying dus...

AI Technical Summary

Problems solved by technology

The principle of dust reduction is to impact the dust-producing space of the pick with mist-like pressure water jets, wet the coal body with atomized water, and capture flying dust. The spray dust suppression effect of the coal machine (the total dust dust suppression efficiency is 50-60%, and the respiratory dust dust suppression efficiency is only 20-30%).
