Intelligent coal-mine gas extraction pump station and working method thereof

Abstract

The invention relates to an intelligent coal-mine gas extraction pump station. The intelligent coal-mine gas extraction pump station comprises a control device; the control device is connected with aplurality of frequency converter; each frequency converter is connected with a water ring type vacuum pump; a contactor is arranged between each water ring type vacuum pump and each frequency converter; a control loop of the contactor is electrically connected with the control device; the intelligent coal-mine gas extraction pump station also comprises a water tank, a water inlet pipeline, a waterdischarge pipeline, a gas discharge pipeline and a gas extraction pipeline; a circulating water inlet of the water ring type vacuum pump communicates with the water tank through the water inlet pipeline; a circulating water outlet of the water ring type vacuum pump communicates with the water tank through the water discharge pipeline; a gas extraction port of the water ring type vacuum pump communicates with a coal-mine tunnel through the gas extraction pipeline; and a gas discharge port of the water ring type vacuum pump communicates with the outside through the gas discharge pipeline. The invention also discloses a working method of the intelligent coal-mine gas extraction pump station.

Description

technical field [0001] The invention relates to a mine safety device, in particular to an intelligent coal mine gas drainage pumping station and a working method thereof. Background technique [0002] In the process of coal mining, due to the large amount of gas contained in the coal seam, explosion disasters are prone to occur, which brings great danger to mining. In order to ensure the safe production of coal mines and the personal safety of employees, and prevent gas disasters, we urgently need to design a safety device in the process of coal mining, so that it can go deep into the site and directly drain the gas, and transport the gas to the ground through pipelines for utilization . [0003] Chinese patent CN205349409U discloses a "mine-used mobile gas pumping station", which reduces labor intensity, is conducive to safe production, and saves a lot of material consumption, but it has the following problems: [0004] (1) There is only one set of water ring vacuum pump ...

AI Technical Summary

Problems solved by technology

[0004] (1) There is only one set of water ring vacuum pump in the whole pump station, which lacks redundant design, the system is not reliable enough, and needs to be shut down during maintenance, which affects continuous use

[0005] (2) The existing coal mine gas drainage pumping stations are operated manually on duty, which cannot realize intelligence and automation
