The present invention relates to a kind of ventilation installation, particularly relate to a kind of coal mining machine roller ventilation installation.
Background technology
Coal-winning machine is the nucleus equipment of fully-mechanized mining working, mainly completes the coal breakage of coal-face and coalings.Coal-winning machine can produce a large amount of dust and gas in the process of work.Because down-hole coal excavation face-airing situation is poor, gas can be gathered in coal mining machine roller rib side.In order to suppress dust from flying, avoiding cylinder spark to cause gas explosion, and improving coal miner's working environment, during coal-winning machine work, cooling spray system must be had.
At present, cooling spray system is divided into internal spraying system and outer spray system, and internal spraying system is that water under high pressure is directly flowed to cylinder nozzle, sprays, and forms spraying water curtain.Pick cooling and dust cleaning are mainly carried out in the effect of the spraying water curtain formed, but not obvious to the effect of dispersing of gas.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of dirt effect and disperse the coal mining machine roller ventilation installation of gas of cylinder of going out that can improve spraying system.
In order to solve the problems of the technologies described above, coal mining machine roller ventilation installation provided by the invention, rocking arm is provided with hollow shaft, described hollow shaft is through adopts sky side and rib side, one end of described hollow shaft is provided with cylinder, in described cylinder, internal spraying system is installed, central water tube is axially arranged with in described hollow shaft, described central water tube one end is connected with described internal spraying system, the other end is connected with the second water pipe, cavity is formed between described central water tube and described hollow shaft, first water pipe to enter in described cavity from adopting sky side and to install nozzle in the end of the first described water pipe.
Described central water tube is located on the longitudinal center line of described hollow shaft.
The water inlet end of described hollow shaft is connected by bearing with bearing gland, described bearing gland is fixed on end cap, install oil sealing in described bearing outer end, and give described bearing axial location with back-up ring, described central water tube is connected with the second described water pipe by water seal.
The first described water pipe and the second water pipe are fixed on described rocking arm by pipeline fixed block.
The water side of described hollow shaft is connected by attachment screw with support set, described support set is fixed on gland, described gland is fixed on cylinder coupling sleeve, described cylinder coupling sleeve is fixedly connected with described cylinder, add the first sealing ring at described support set and described hollow shaft, add the second sealing ring at described support set and described end cap.
Described central water tube one end is fixed in described hollow shaft, and the other end is connected with the second described water pipe by described water seal.
Adopt the coal mining machine roller ventilation installation of technique scheme, the central axis of rocker arm of coal mining machine drum segment is hollow structure, be located at hollow structure center and load a larger-diameter hollow shaft, and pass into the less central water tube of a diameter at this hollow shaft center, provide press water by this central water tube to internal spraying system.Peripheral hollow parts is formed between inner wall of hollow shaft and central water tube outer wall wall, peripheral hollow parts then sprays high-velocity flow by another root water pipe by nozzle, high-velocity flow drives rapid air movement in hollow shaft, Venturi effect is utilized (can low pressure to be produced around flow at high speed gas, thus produce suction-operated) make to form negative pressure in hollow shaft, thus make air suck hollow shaft from the goaf side of rocking arm, and go out from rib side spray with high-velocity flow, reaching ventilates dispels the effect of gas.
The beneficial effect that the present invention produces is:
1, by the water atomization ejection in central water tube, thus the effect of adsorption of dust is reached.
2, the air sucked can dispel the gas accumulating in rib side cylinder, prevents gas explosion.
In sum, the present invention is a kind of dirt effect and disperse the coal mining machine roller ventilation installation of gas of cylinder of going out that can improve spraying system.
