Description
Technical field
The utility model relates to emulsion liquid recovering system, especially relates to the hydraulic system reclaiming emulsion for coal-face.
Background technology
In mechanical coal mining work plane, hydraulic support common configuration has backwash filter (manual or electromagnetic pilot backwash), backwash filter carries out back flush filter core according to some cycles with automatic or manual mode of operation, the impurity filtered in backwashing filter core is washed away by high-pressure emulsion, to improve the application life of backwash filter filter core, the emulsion after backwash is drained in work plane goaf in a large number by sewage backwash pipe.Meanwhile, when hydraulic support normally works, the safety valve that hydraulic support column, the jack supporting with hydraulic support configure will carry out unloading pressure and discharge emulsion when reaching rated pressure, this emulsion flows in work plane equally.The mode of above two kinds of discharge emulsions all causes the waste of a large amount of emulsion.Further, the chemical addition agent contained in emulsion also causes the pollution of underground water and environment.
Summary of the invention
The utility model object is to provide a kind of hydraulic system reclaiming emulsion for coal-face.
For achieving the above object, the utility model takes following technical proposals:
The hydraulic system reclaiming emulsion for coal-face described in the utility model, comprise the multiple hydraulic support hydraulic control unit being arranged in down-hole coal excavation work plane, described each hydraulic support hydraulic control unit includes hydraulic vertical prop, hydraulic jack reversible lock and the hydraulic test supporting with hydraulic support, and for controlling described hydraulic vertical prop, hydraulic jack reversible lock, the hydraulically operated valve group of the hydraulic test supporting with hydraulic support, the backwash emulsion import of described hydraulically operated valve group is communicated with backwash filter liquid outlet, the leakage fluid dram of described backwash filter is communicated with liquid back pipe road by blow-off line, the inlet of backwash filter is communicated with high pressure water influent pipeline by stop valve, described liquid back pipe road is passed through back liquid filter and is communicated with emulsion pump box inlet, described emulsion pump box liquid outlet is communicated with described high pressure water influent pipeline by emulsion power pack, the backwash emulsion liquid return hole of described hydraulically operated valve group is communicated with liquid back pipe road by cutout valve, the column safety valve water conservancy diversion interface of described hydraulic vertical prop, the jack safety valve water conservancy diversion interface of hydraulic jack reversible lock are communicated with liquid back pipe road respectively by pipeline.
The utility model beneficial effect is: coupled together by the liquid interface pipeline that unloads of safety valves all on coal face hydraulic support, backwash filter leakage fluid dram is connected, finally be linked in liquid back pipe road, between liquid back pipe road and emulsion pump box, liquid filter is set back, emulsion after backwash is returned the contaminant filter in liquid, emulsion is recycled, thus reach the object reclaiming whole coal-face backwash emulsion, reduce the consumption of backwash emulsion, save mining costs, decrease the pollution of backwash emulsion to environment simultaneously.
Accompanying drawing explanation
Fig. 1 is Hydraulic System Principle schematic diagram described in the utility model.
Detailed description of the invention
As shown in Figure 1, the hydraulic system reclaiming emulsion for coal-face described in the utility model, comprise the multiple hydraulic support hydraulic control unit 1 being arranged in down-hole coal excavation work plane, described each hydraulic support hydraulic control unit 1 includes hydraulic vertical prop 2, hydraulic jack reversible lock 3 and the hydraulic test 4 supporting with hydraulic support, and for controlling described hydraulic vertical prop 2, hydraulic jack reversible lock 3, the hydraulically operated valve group 5 of the hydraulic test 4 supporting with hydraulic support, the backwash emulsion import of described hydraulically operated valve group 5 is communicated with backwash filter 6 liquid outlet, the leakage fluid dram of described backwash filter 6 is communicated with liquid back pipe road 8 by blow-off line 7, the inlet of backwash filter 6 is communicated with high pressure water influent pipeline 10 by stop valve 9, described liquid back pipe road 8 is passed through back liquid filter 11 and is communicated with emulsion pump box 12 inlet, described emulsion pump box 12 liquid outlet is communicated with described high pressure water influent pipeline 10 by emulsion power pack 13, the backwash emulsion liquid return hole of described hydraulically operated valve group 5 is communicated with liquid back pipe road 8 by cutout valve 14, the column safety valve 15 water conservancy diversion interface of described hydraulic vertical prop 2, the jack safety valve 16 water conservancy diversion interface of hydraulic jack reversible lock 3 are communicated with liquid back pipe road 8 respectively by pipeline.
