Abstract
The utility model discloses a remote-control type backwashing filter. The remote-control type backwashing filter comprises a filter main body, wherein the filter main body is equipped with a liquid inlet, a liquid outlet, a valve element and a filter element; in a working state, the liquid inlet passes through the valve element and the filter element in sequence to be communicated with the liquid outlet; the filter main body is equipped with a backwashing control opening and a drain outlet; the backwashing control opening is communicated with a reversing control cavity of the valve element; after the valve element is reversed, the liquid outlet passes through the filter element and the valve element in sequence to be communicated with the drain outlet. The backwashing control opening is connected with a backwashing functional opening of a main operating valve of the bracket. The valve element can be hydraulically controlled to reverse by the backwashing control opening to carry out backwashing, so that labor intensity of workers is alleviated; moreover, the remote-control type backwashing filter disclosed by the utility model can be used on manual-control and electrohydraulic-control brackets.
Description
Technical field
The utility model relates to a kind of coal mine underground hydraulic support frame parts, relates 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 obtains 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, when normal feed liquor, two filter cores are worked simultaneously, in the time that 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 use 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 is also with to hidden danger.
Utility model content
It is low that the purpose of this utility model is to provide a kind of labour intensity, and the use remote control formula backwash filter that can make on the support of manual control and electrichydraulic control.
The purpose of this utility model is achieved through the following technical solutions:
Remote control formula backwash filter of the present utility model, 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 control mouth and sewage draining exit, described backwash control mouth communicates 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.
The technical scheme being provided by above-mentioned the utility model can be found out, the remote control formula backwash filter that the utility model embodiment provides, because filter body is provided with backwash control mouth and sewage draining exit, backwash control mouth communicates with the commutation control chamber of spool, after spool commutation, liquid outlet communicates with sewage draining exit by filter core, spool successively, can be by the long-range hydraulic control spool commutation of backwash control mouth, carry out backwash, reduce 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 utility model embodiment.
The specific embodiment
To be described in further detail the utility model embodiment below.
Remote control formula backwash filter of the present utility model, 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 control mouth and sewage draining exit, and described backwash control mouth communicates 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 control mouth is connected with the counter-flush mouth of the main control valve of support.
Remote control formula backwash filter of the present utility model, 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 backwash control mouth KA, KB connect the counter-flush mouth of the main control valve of support, play 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 when normal use, enter support from liquid outlet POUT.
In the time that the filter core 3 in left side occurs to stop up, control liquid and enter backwash control mouth KA from the counter-flush mouth of the main control valve of support, left side spool 2 commutates, a part of high pressure liquid of liquid outlet POUT is from filter core 3 inside in left side enter left side spool 2, discharge from sewage draining exit RA, the impurity of filter core 3 outsides that are attached to left side is rinsed well.
In the time that the filter core 3 on right side occurs to stop up, control liquid and enter backwash control mouth KB from the counter-flush mouth of the main control valve of support.
The utility model installation compared with manual backwashing filter device, maintenance, easy to clean, greatly reduce labour intensity.
The utility model is cheap compared 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; it is only the preferably specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
