Description

Technical Field

[0002] The fully mechanized mining face of the mine adopts high-pressure filters to process solid particles in the underground emulsion, protect downstream equipment, and avoid clogging of pipelines and equipment. In order to adapt to the complex environment underground, the high-pressure filter is usually designed to be compact and easy to install. The pump box adds the mine water to the emulsion and pumps it to the high-pressure filter. Due to the different water quality of the mine water in each mine, solid particles are easily mixed in the mine water, which leads to the problem that the pump box and the high-pressure filter are easily blocked and the mine water is not thoroughly filtered. The mine water output by the high-pressure filter enters the hydraulic support. The incompletely filtered mine water is likely to cause problems in the hydraulic support pipeline. Therefore, the high-pressure filter element needs to be replaced frequently. The high-pressure resistant materials and design make the cost relatively high. Manual replacement of the high-pressure filter element delays other operations on site, affects production efficiency, and increases operating costs. Therefore, a filtering device that can prevent the high-pressure filter from being blocked is needed. Utility Model Content

[0036] The filtering accuracy of the mine water filter 20 is lower than that of the high pressure filter 30 .

[0037] According to the present solution, the mine water filter 20 and the high-pressure filter 30 are installed on the base 10. The mine water filter 20 performs preliminary filtering on the mine water, filters solid particles and dirt in the mine water, and prevents solid particles from clogging the high-pressure filter 30.

[0062] The principle of the utility model is:

[0063] The mine water of the fully-mechanized working face is filtered by the filter device and then delivered to the hydraulic support for use. The filter screen of the mine water filter 20 filters solid particles and other substances in the mine water. According to the different water quality of the mine water of different fully-mechanized working faces, the filter screen can be double-layer or multi-layer. The mine water filtered by the filter screen enters the filter element of the mine water filter 20, and the filter element further filters the mine water.

[0064] The mine water is initially filtered through the mine water filter 20 to substantially remove solid particles in the mine water.

[0065] The mine water filtered by the mine water filter 20 is delivered to the pump box, and the pump box adds emulsion to the mine water output by the mine water filter 20, so that the mine water meets the use requirements of the hydraulic support.
