Problems solved by technology

[0004] Water softening method When the resin adsorbs calcium and magnesium ions to a certain degree of saturation, the hardness of the effluent will increase continuously. This method does not work well for a long time, and cannot completely change the water quality, and consumes a large amount of water softener; the artificial pickling method requires Shutting down and dismantling the pump consumes manpower and material resources, causing corrosion damage to equipment, and waste liquid pollutes water quality and the environment
The high-pressure water washing method cannot completely remove the scale attached to the deep layer, wasting water and manpower; the electronic water treatment method consumes energy, and the electromagnetic environment is not convenient for use in coal mine gas pumping stations and other environments

Abstract

The invention discloses an online automatic descaling device of a movable type water ring vacuum pump for a coal mine. The device comprises an intrinsic safety control box, a control box, a heating starter, a filter starter, a filter motor, a second-stage filter, a first-stage filter, a circulation pump, a pump motor, a steel ball valve, a hose, and a liquid medicinal case; the intrinsic safety control box, a pump starter, the heating starter and the filter starter are connected with the control box through a cable, a water quality detection module is arranged on a circulation pipeline betweenthe second-stage filter and a first-stage filter through the steel ball valve, and the two-stage filter, a liquid level sensor, a temperature sensor and the water quality detection module are connected with the control box through a cable. The device has the beneficial effects that the descaling aim of coal mine water ring vacuum pumps and other devices is achieved, water scales deposited on theinner wall of the water ring vacuum pump, an impeller, a distribution disc and the like can be thoroughly removed, automatic descaling and autonomous and accurate judgment of the descaling effect canbe achieved, manpower cost is reduced, and the pump station use efficiency is improved.

Description

technical field [0001] The invention relates to the field of cleaning and descaling devices for water ring vacuum pumps, in particular to an online automatic descaling device for movable water ring vacuum pumps used in coal mines. Background technique [0002] In the coal mine gas drainage system, the fouling of equipment such as water ring vacuum pumps is a serious problem that plagues coal mines. After the water ring vacuum pump has been running for a period of time, the inner surface of the pump casing and the impeller are covered by a hard scale layer. If the treatment is not timely, a pump jam accident will occur, and there is a danger of twisting the pump shaft or burning the motor, which will affect the efficiency of the vacuum pump. Increase the number of unplanned shutdowns, endangering the gas drainage system and mine safety. [0003] At present, the existing descaling methods in coal mines mainly include softened water, artificial pickling or high-pressure water ...
