Abstract
The invention discloses a remote control type backwashing filter which comprises a filter main body, wherein the filter main body is provided with a liquid inlet, a liquid outlet, valve cores and filter cores; in a working state, the liquid inlet is communicated with the liquid outlet sequentially through the valve cores and the filter cores; the filter main body is provided with a backwashing control hole and a drain outlet, the backwashing control hole is communicated with reversing control cavities of the valve cores, and the liquid outlet is communicated with the drain outlet through the filter cores and the valves after the filter cores are reversed. The backwashing control hole is connected with a backwashing function hole of a main control valve of a bracket. The reversing of the valve cores can be remotely controlled through the backwashing control hole so as to perform backwashing, thus the labor intensity of a worker is alleviated, and the remote control type backwashing filter can be used on manual-control brackets and electrohydraulic-control brackets.
Description
Technical field
The present invention relates to a kind of coal mine underground hydraulic support frame parts, relate in particular to a kind of remote control formula backwash filter.
Background technology
At present, backwash filter is as one of critical elements in high-end hydraulic support system, in being used, down-hole obtained good effect, be substituted traditional tubular filter, can dismantle filter core, directly use counter-flush that filter element cleaning is clean, reduce labour intensity, improve production efficiency, met the highly efficient and productive needs of Modern coal mines.
Prior art one:
Down-hole manual backwashing filter device has two filter cores, during normal feed liquor, two filter cores are worked simultaneously, when impurity stops up filter core, rotate the handle of one of them filter core A, make it to communicate with the external world, the high pressure liquid of another filter core B oppositely enters filter core A, and the impurity being attached on filter core A is drained into the external world.
At least there is following shortcoming in above-mentioned prior art one:
Because backwash filter is generally contained on the linkage of hydraulic support, down-hole narrow space determined operator very easily operating grip make it recoil.And due to the high pressure that down-hole emulsion system is 31.5MPa, the moment of operating grip is very large, more having increased operator is working strength, wastes time and energy.
Prior art two:
The difference of down-hole automatic backwashing filter and manual backwashing filter device is to use electromagnetic priority valve and main valve plug to replace operating grip, to automatically recoiling after inlet outlet pressure differential automatic decision.
At least there is following shortcoming in above-mentioned prior art two:
Because automatic backwashing filter need to be used on the hydraulic support of supporting electric hydraulic control, therefore this method is only applicable to electric hydraulic control support, and has greatly increased cost.And owing to introducing electric equipment, the safety in production of down-hole has also been with to hidden danger.
Summary of the invention
The object of this invention is to provide a kind of labour intensity low, and the use remote control formula backwash filter that can make on the support of manual control and electrichydraulic control.
The object of the invention is to be achieved through the following technical solutions:
Remote control formula backwash filter of the present invention, comprise filter body, described filter body is provided with inlet, liquid outlet, spool, filter core, under duty, described inlet communicates with described liquid outlet by described spool, filter core successively, it is characterized in that, described filter body is provided with backwash and controls mouth and sewage draining exit, described backwash is controlled mouth and is communicated with the commutation control chamber of described spool, after described spool commutation, described liquid outlet communicates with described sewage draining exit by described filter core, spool successively.
As seen from the above technical solution provided by the invention, the remote control formula backwash filter that the embodiment of the present invention provides, because being provided with backwash, filter body controls mouth and sewage draining exit, backwash is controlled mouth and is communicated with the commutation control chamber of spool, after spool commutation, liquid outlet communicates with sewage draining exit by filter core, spool successively, can control a mouthful long-range hydraulic control spool by backwash commutates, carry out backwash, reduced labor strength, and can use on the support of manual control and electrichydraulic control.
Accompanying drawing explanation
The structural representation of the remote control formula backwash filter that Fig. 1 provides for the embodiment of the present invention.
The specific embodiment
To be described in further detail the embodiment of the present invention below.
Remote control formula backwash filter of the present invention, its preferably the specific embodiment be:
Comprise filter body, described filter body is provided with inlet, liquid outlet, spool, filter core, under duty, described inlet communicates with described liquid outlet by described spool, filter core successively, it is characterized in that, described filter body is provided with backwash and controls mouth and sewage draining exit, and described backwash is controlled mouth and communicated with the commutation control chamber of described spool, after described spool commutation, described liquid outlet communicates with described sewage draining exit by described filter core, spool successively.
Described filter body is provided with two spools and two filter cores.
Described backwash is controlled mouth and is connected with the counter-flush mouth of the main control valve of support.
Remote control formula backwash filter of the present invention, has reduced labor strength, and can use on the support of manual control and electrichydraulic control.
Specific embodiment:
As shown in Figure 1, when filter body 1 is installed, inlet PIN connects pumping plant feed liquor, and liquid outlet POUT connects support feed liquor, and the counter-flush mouth that mouthful KA, KB connect the main control valve of support is controlled in backwash, plays Long-distance Control effect, and sewage draining exit RA, RB are for sewage backwash.
After emulsion enters two filters 3 from inlet PIN enters two spools 2 again during normal use, from liquid outlet POUT, enter support.
When the filter core 3 in left side occurs to stop up, control liquid and enter a backwash control mouthful KA from the counter-flush mouth of the main control valve of support, 2 commutations of left side spool, a part of high pressure liquid of liquid outlet POUT enters the spool 2 of left side from filter core 3 inside in left side, from sewage draining exit RA, discharge, the impurity that is attached to filter core 3 outsides in left side is rinsed well.
When the filter core 3 on right side occurs to stop up, control liquid and enter a backwash control mouthful KB from the counter-flush mouth of the main control valve of support.
The present invention compares installation, maintenance, easy to clean, greatly reduces labour intensity with manual backwashing filter device.
The present invention compares cheap with automatic backwashing filter, widely applicable, not only can be applied on electrichydraulic control support, also can be applied on manually operated support, and security is higher.
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.
