Automatic liquid adding device of underground coal mine emulsified liquid

Abstract

The invention relates to an automatic liquid adding device of an underground coal mine emulsified liquid. The particular technical scheme is that the emulsified liquid adding device comprises an emulsified liquid tank, a liquid intake pipe, a liquid discharge pipe, a filter, a check valve, a liquid level switch and an emulsified liquid adding pump, wherein two ends of the emulsified liquid tank are connected with two flanges; the liquid intake pipe and the liquid discharge pipe are respectively connected to the emulsified liquid tank and the liquid adding pump; a liquid guide pipe at the other side of the liquid adding pump is connected with an emulsified liquid barrel; the liquid level switch is installed at the top of the emulsified liquid tank. The automatic emulsified liquid adding device is characterized by also comprising an automatic control system consisting of a vacuum magnetic force starter and an anti-explosion button which can be used for controlling the liquid adding pump. The automatic emulsified liquid adding device consists of simple parts, the design and manufacture are very simple, meanwhile, the use is very convenient; parts are also very convenient to replace when being damaged; the automatic emulsified liquid adding device can be adaptive to severe underground working environment, cannot generate adverse environmental influences, and is very suitable for underground coal mine working environment.

Description

technical field [0001] The invention belongs to the field of underground coal mine automation equipment, and in particular relates to an automatic liquid feeding device for underground emulsion in coal mines. Background technique [0002] In the comprehensive mechanized coal mining face, the appropriate emulsion ratio is an important condition to ensure the normal operation of the hydraulic support. At the same time, it can maximize the production efficiency of the support and reduce the maintenance cost of the support. Insufficient emulsion will lead to wear and rust of the bracket, and a large number of bacteria will corrode the equipment, causing the blockage of the system filter, causing the bracket to run slowly or even inoperable, affecting normal production. Due to the influence of roadway transportation conditions in some coal mines, after the emulsion is transported to the winch of the roadway stringer, the emulsion in the large bucket can only be manually pumped in...
