specific Embodiment approach

[0013] Underground water inlet filter station for coal mine of the present invention, its preferred embodiment is:

[0014] Including two sets of filter systems, one for the other, each filter system includes two sets of filter assemblies connected in parallel, the two sets of filter assemblies are arranged on the same liquid distribution plate, and the outlet of each set of filter assemblies is equipped with a liquid return A circuit breaker valve, and a drain valve is provided on the liquid distribution plate of each set of filter assemblies.

[0015] The inlets of the two sets of filtration systems are set on the same liquid inlet manifold, and the outlets of the two sets of filter systems are set on the same liquid outlet manifold.

[0016] The filter assembly includes a filter, a filter core is arranged inside the filter, and a cylinder cover is arranged on the upper part of the filter.

specific Embodiment

[0018] Such as figure 1 , figure 2 , image 3 As shown, in order not to affect the normal operation of the downhole working face, the hydraulic cleaning water system is filtered in a mode of using one for one in specific embodiments. Firstly, the filter 4 and the cylinder head 5 are screwed together to fix them. Then connect the two sets of filter components to the same liquid distribution plate through threads to realize parallel connection and improve the filtration efficiency. In order to achieve the purpose of using one as a backup, two liquid distribution plates are installed on the support frame 1 for switching liquid supply, which is convenient for daily inspection and maintenance. In order to prevent the filters on the same liquid distribution board from interfering with each other during sewage discharge, a liquid return cut-off valve 11 is provided at the outlet of each filter, and finally the filtered clean liquid is supplied to the hydraulic system.

Abstract

The invention discloses an underground inlet water filtering station for a coal mine, which comprises two sets of filtering systems, wherein one set of filtering system is used and the other set of filtering system is standby; each set of filtering system comprises two groups of filter assemblies which are connected in parallel; the two groups of filter assemblies are arranged on the same liquid distribution plate; an outlet of each group of filter assembly is provided with a return liquid shut-off valve; and a blowdown valve is arranged on the liquid distribution plate of each group of filter assembly. The underground inlet water filtering station for the coal mine stably operates, is convenient to operate, has a good filtering effect and is suitable to use on an underground working surface of the coal mine; the action reliability of an underground hydraulic element is obviously improved; the damage rate of the hydraulic element is greatly reduced.

Description

technical field [0001] The invention relates to a water filtering device for underground working faces in mines, in particular to an underground water inlet filtering station for coal mines. Background technique [0002] In order to ensure clean water in the underground working face of the coal mine and improve the working stability of the hydraulic system of the support of the working face, according to the concept of "multi-stage filtration system", the inlet water filtration equipment is introduced in the underground coal mine. [0003] Most of the filtering devices currently used are distributed filters, that is, filters that meet the requirements for water quality and water flow are installed at each water-using equipment. Although this can meet the requirements of equipment for water quality and quantity, many scattered and different The maintenance and overhaul of filters with models and specifications brings a lot of inconvenience to daily production.
