Automatic water release device for pressure measuring ring of mine main ventilator

Abstract

The invention provides an automatic drain device for a pressure measuring ring of a mining main ventilator. The automatic drain device solves the problems that the water accumulation amount can not be known accurately, water is drained only when obvious influence is generated, and time and labor are consumed when the current manual drain mode is used. The automatic drain device for the pressure measuring ring of the mining main ventilator comprises an upper water storage tank and a lower water storage tank which are arranged in an upper and lower mode. The top of the upper water storage tank is provided with an upper water storage pipe. An upper cone valve is arranged in the upper water storage pipe. The upper water storage tank and the lower water storage tank are communicated through a lower water storage pipe. A lower cone valve is arranged in the lower water storage pipe. The bottom of the lower water storage tank is provided with a drain pipe. The upper water storage tank is provided with a negative pressure balance valve and a ventilation valve. The negative pressure balance valve and the ventilation valve are connected with the lower cone valve through a connecting rod. For the pressure measuring ring of the mining main ventilator, the automatic drain device which can solve the problem of water accumulation of the pressure measuring ring is designed for the first time; the automatic drain device can operate under the high negative pressure condition, and has the advantages of being small in size, accurate in operation, reliable and the like.

Description

technical field [0001] The invention belongs to the technical field of mining equipment, and relates to negative pressure equipment used in a pressure measuring ring of a mine main ventilator, in particular to an automatic water discharge device for the pressure measuring ring of a mine main ventilator. Background technique [0002] In the air duct of the inlet collector of the main ventilator in the coal mine, due to the high humidity and high negative pressure of the air flow, it will condense into a large amount of water after a period of time and gather in the pressure measuring ring. If the accumulated water cannot be released in time, the pressure measuring ring will be blocked, which will not only affect the online monitoring of the performance of the ventilator, but also affect the correct identification and judgment of the mine production ventilation status by the coal mine management unit, which will bring hidden dangers to the safe production of the coal mine.

AI Technical Summary

Problems solved by technology

This method of manually draining water cannot accurately understand the amount of accumulated water, and it is often drained only when the performance test of the fan has a significant impact. Moreover, the operating environment in the fan room is poor, and the process of manually draining water is time-consuming and laborious.
