Description
Technical field
The utility model relates to a kind of go out coal mining unit of dirt and height-regulating device of airborne clear water high pressure that has.
Background technology
At present, in the coal industry field, in the coal mining unit cut coal mining engineering, often take distinguished and admirable the cleaning by the surface, coal seam of coal mining unit cut under the coal mining unit, this distinguished and admirable dust that causes tends to influence operating personnel's breathing.If the gas bearing capacity in the mine is big, then need to adopt bigger air distribution amount with the gas bearing capacity in the dilution mine, but the increase of air distribution amount can be quickened flying upward of dust, dust concentration in the working environment can increase thereupon, for this reason, existing coal mining unit adopts from pressing the mode that supplies water to reduce the concentration of dust.
Yet, because the pressure that supplies water is less from pressing, the water smoke that produces under the effect of this pressure is also less, while water smoke is the static electrification lotus not, thereby make water smoke not adsorb effectively and the humidifying dust to increase the weight of dust, can not satisfy the requirement of depositing dust far away so only rely on, and water supply volume is bigger from pressing to supply water; In addition, the height-regulating device of existing coal mining unit is to adopt hydraulic oil to heighten mode, makes the bigger with oil mass of coal mining unit like this, and because the seepage of hydraulic oil can cause greasy dirt to dye.
Therefore, be necessary in fact to design and a kind ofly be applied to have airborne clear water high pressure and go out the coal mining unit of dirt and height-regulating device to overcome above-described defective.
The utility model content
The purpose of this utility model is to provide a kind of go out coal mining unit of dirt and clear water height-regulating device of airborne clear water hydraulic pressure that has, make water smoke that airborne go out dirt and clear water height-regulating device eject have electrostatic charge and come dust in effective absorbed air, thereby under guaranteeing the less prerequisite of water supply volume, effectively reduce the dust content in the coal-winning machine working environment, and reduce the grease contamination that the coal mining unit causes.
To achieve these goals, of the present utility model to have the go out coal mining unit of dirt and height-regulating device of airborne clear water high pressure be design like this: this has the go out coal mining unit of dirt and height-regulating device of airborne clear water high pressure and comprises coal-winning machine and be installed on airborne clear water high pressure on the coal-winning machine go out dirt and height-regulating device, wherein airborne clear water high pressure go out hydraulic pressure height-regulating device that dirt and height-regulating device comprise booster pump, connect with booster pump, with the sprayer of hydraulic pressure height-regulating device parallel connection and be connected the transmission pipeline of these assemblies.
Of the present utility model have airborne clear water high pressure and go out the coal mining unit of dirt and height-regulating device by utilizing said structure, can be under the less prerequisite of water supply volume, water smoke by the static electrification lotus that generates effectively reduces the dust content in the coal-winning machine working environment, and in the usefulness oil mass that reduces the coal mining unit, reduce the grease contamination that the coal mining unit causes.
Description of drawings
Fig. 1 has a go out schematic diagram of coal mining unit of dirt and height-regulating device of airborne clear water high pressure for of the present utility model.
The specific embodiment
Of the present utility model have the go out coal mining unit 1 of dirt and height-regulating device of airborne clear water high pressure and comprise coal-winning machine 3 and be installed on airborne clear water high pressure on the coal-winning machine 3 go out dirt and height-regulating device 2.And coal-winning machine 3 is provided with coal-cutting drum 30 in its two ends, and go out dirt and height-regulating device 2 of wherein airborne clear water high pressure comprises cooler 20, airborne pressurized pump station 22, hydraulic pressure height-regulating device 24, sprayer 26, pressure regulator valve 28 and connect the transmission pipeline of these assemblies.Wherein cooler 20 and airborne pressurized pump station 22 are one another in series by pipeline, and hydraulic pressure height-regulating device 24 and sprayer 26 are connected by the pipeline realization with airborne pressurized pump station 22 by the pipeline back that is connected in parallel to each other.Wherein airborne pressurized pump station 22 comprises booster pump 220 and the adjusting control valve 222 that is in series with booster pump 220.
In a preferred implementation of the present utility model, booster pump 220 adopts existing in the industry at present horizontal three-stage plunger reciprocating pump, select explosion separation motor, gear, bent axle, connecting rod slider, plunger and hydraulic cylinder for use, wherein the output shaft of motor passes through primary gear speed reducing, drive the crankshaft rotating of crank throw, it is reciprocating to drive plunger through connecting rod slider again, makes water suck and discharge through liquid suction valve in pump head, thereby make electric energy be converted into the hydraulic pressure energy, thereby improve the hydraulic pressure that comes water; The hydraulic pressure height-regulating device then adopts hydraulic pressure to heighten jack to replace prior oil pressure and heighten jack, thereby reduces the grease contamination of coal mining unit 1.
Of the present utility modelly have airborne clear water high pressure and go out in the process of coal mining unit 1 of dirt and height-regulating device using, come current to go out behind the parts of the needs cooling on the coal mining unit 1 of dirt and height-regulating device through having airborne clear water high pressure, it enters the distributing valve (not shown) again through water intaking valve reducing valve (not shown), liquid mechanism is used in each cooling of dispensing, comes water at first to enter cooler 20 through piping then.Come water to enter airborne pressurized pump station 22 in the device 20 cooling backs that are cooled by pipeline: at first, come water to enter booster pump 220, hydraulic pressure increase water afterwards enters control valve 28, can control the hydraulic pressure of water by this control valve 28.Then, come water to enter hydraulic pressure height-regulating device 24 and sprayer 26 respectively through piping, wherein sprayer 5 surfaces have some spray orifice (not shown).Through behind the airborne pressurized pump station 22, come the hydraulic pressure of water stronger, during current process spray orifice, owing to the effect that is subjected to big frictional force produces electrostatic charge, its electrostatic charge of dependence can effectively be adsorbed the dust in the mine after current were ejected, thereby was guaranteeing that the less prerequisite of water supply volume is issued to the purpose of high-effective dust-removing.Simultaneously, the carried charge of the electrostatic charge that produces behind the current process spray orifice is less, and the water yield is also very limited, does not become potential safety hazard so can not cause gas explosion.
