Problems solved by technology

The currently used emulsion filtration station mainly relies on manual shutdown to perform backwashing, inspection, maintenance, etc., so that the emulsion pump station cannot operate continuously, production stops, work efficiency is low, and there is no pressure differential overload alarm and protection. If not If backwashing, cleaning or replacing the filter element in time, the resistance will increase, the filter element will be broken, and the equipment will be damaged, which will affect the safety of coal mine production.

Abstract

The invention relates to an emulsion high-pressure automatic back-flushing filtering device which comprises at least one group of filtering unit, wherein the filtering unit comprises a filtering body.The invention is characterized in that the filtering body is a flat square integral structure, the front part of the filtering body is provided with a two-way liquid inlet hole, a two-way liquid outlet hole and a two-way back-flushing drain hole which are laterally distributed, and the rear part of the filtering body is provided with at least three longitudinally distributed filtering holes. Theinvention has the advantages of no leakage, favorable rigidity, high capability of bearing high pressure, high safety, convenience in removing a filter element, compact structure and the like.

Description

technical field [0001] The invention relates to a filter device specially used for underground coal mines and installed on an emulsion delivery pipeline between an emulsion pump station and a hydraulic support, in particular to a high-pressure automatic backwash filter device for emulsion. Background technique [0002] With the advancement of science and technology and the consideration of human safety, the degree of automation of coal mine equipment continues to increase, and the requirements for the cleanliness of the emulsion are getting higher and higher. The emulsion filter device plays a certain role in ensuring the cleanliness of the emulsion. The currently used emulsion filtration station mainly relies on manual shutdown to perform backwashing, inspection, maintenance, etc., so that the emulsion pump station cannot operate continuously, production stops, work efficiency is low, and there is no pressure differential overload alarm and protection. If not If backwashing...
