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
The present invention relates to a kind of ore deposit mining face under mine water filtration device, relate in particular to a kind of coal mine underground water inlet filter station.
Background technology
Clean for guaranteeing colliery mining face under mine water, the job stability of raising force piece hydraulic system according to the theory of " multistage filtering system ", has been introduced water inlet filter plant under coal mine.
The filter great majority that use are at present dispersed filter, the filter meeting water quality and water amount requirement is set at each watering equipment place, although can meet like this requirement of equipment to water quality and quantity, but maintenance and the maintenance of many polydisperse, different models and the filter of specification, bring inconvenience to daily production.
Summary of the invention
The coal mine underground water inlet filter station that the object of this invention is to provide a kind of stable, easy to operate, good filtration effect.
The object of the invention is to be achieved through the following technical solutions:
Coal mine underground water inlet filter station of the present invention, comprise with one for one two cover filtration systems, every cover filtration system comprises two set filter assemblies parallel with one another, two set filter assemblies are located on same fluid proportion plate, the outlet of every set filter assembly is provided with back liquid cutout valve, and the fluid proportion plate of every set filter assembly is provided with blowoff valve.
As seen from the above technical solution provided by the invention, the coal mine underground water inlet filter station that the embodiment of the present invention provides, due to comprise with one for one two cover filtration systems, every cover filtration system comprises two set filter assemblies parallel with one another, two set filter assemblies are located on same fluid proportion plate, the outlet of every set filter assembly is provided with back liquid cutout valve, and the fluid proportion plate of every set filter assembly is provided with blowoff valve.Through the test of time more than a year, the Reliability of Microprocessor of underground hydraulic element significantly improves, and Hydraulic Elements spoilage significantly reduces.This filter station is stable, easy to operate, good filtration effect, is adapted at colliery mining face under mine and uses.

The specific embodiment
To be described in further detail the embodiment of the present invention below.
Coal mine underground of the present invention water inlet filter station, its preferably the specific embodiment be:
Comprise with one for one two cover filtration systems, every cover filtration system comprises two set filter assemblies parallel with one another, two set filter assemblies are located on same fluid proportion plate, and the outlet of every set filter assembly is provided with back liquid cutout valve, and the fluid proportion plate of every set filter assembly is provided with blowoff valve.
The import of two cover filtration systems is located on same feed liquor integrated package, and the outlet of two cover filtration systems is located on same fluid integrated package.
Described filter assemblies comprises filter, in described filter, is provided with filter core, and described filter top is provided with cylinder cap.
Coal mine underground water inlet filter station of the present invention, in the situation that not affecting the normal work of working face, filters the work impurity in hydraulic pressure clean water system, improves the cleannes of clear water, extends the service life of fully-mechanized mining equipment, keeps efficient production efficiency.
Specific embodiment:
As shown in Figure 1, Figure 2, Figure 3 shows, in order not affect the normal work of mining face under mine, in specific embodiment, adopt and hydraulic pressure clean water system is filtered for one pattern with one.First filter 4 and cylinder cap 5 are threaded connection, make it fixing.Then two set filter assemblies are threaded connection on same fluid proportion plate, realize parallel connection, improve filter efficiency.In order to reach with one for one object, so two fluid proportion plates are installed on bracing frame 1, for switching feed flow, be convenient to daily inspection and maintenance.In order to prevent that the filter on same fluid proportion plate from mutually interfering in blowdown, so be equipped with one in the exit of single filter, return liquid cutout valve 11, finally the clean liquid after filtering is supplied with to hydraulic system.
The operation principle of specific embodiment is:
As shown in Figure 3, first open any one in ball valve Q7 (1) and Q7 (2), highly pressurised liquid enters fluid proportion plate through ball valve Q7 (1) or Q7 (2), in fluid proportion plate, be divided into two-way, give two filter feed flows simultaneously, highly pressurised liquid in two filters pass through back respectively liquid cutout valve H11(1 through after filtering) and H11(2) or H11(3) and H11(4), then flock together, finally pass through fluid integrated package 10 to working face feed flow.
When two manometric numerical value difference on same filter surpass specified value, just should implement blowdown, turn on the corresponding Blowoff ball valve Q2(1 of this filter), Q2(2), Q2(3), Q2(4), by being attached to impurity in cartridge surface, get rid of.
When two filter cores of water inlet filter station are worked, adopt same fluid proportion plate directly to distribute feed liquor, so just avoided because too much fluid pressure line annex connects the caused pressure loss, contribute to the accurate pressure of importing and exporting of judging, blowdown in time; The outlet of each filter for molten is all equipped with one and is returned liquid cutout valve, and each filter is not interfered at mutual when working, prevents when blowdown simultaneously, and sewage is counter to flow, and affects the normal work of filter station.
The present invention can carry out from hydraulic system source initial one-level working media and filter, from source, control the inherent cleannes of hydraulic work system medium, for hydraulic system provides comparatively desirable clean working media, alleviate each element filters medium live load of subsystem, further carry the job stability of high comprehensive mining hydraulic system, reduce each class component sealing maintenance engineering, improve unit efficiency, reduce system failure incidence, extend the service life of each class component of hydraulic system.
The above; be only the present invention's specific embodiment preferably, but protection scope of the present invention is not limited to this, is anyly familiar with in technical scope that those skilled in the art disclose in the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
