Abstract
The invention discloses a mining hydraulic double-rotation pulse local ventilator for mine gas control and mine local ventilation, which adopts emulsion as a power source, a hydraulic motor 1 and a hydraulic motor 5 drive an impeller 2 and a machine body to generate double-rotation pulse airflow, and a reticular spiral protective cage 6 covers the outside.
Description
The present invention relates to a kind of hydraulic, double rotary and pulsation type ventilator for local parts for mining use that is used for mine gas prevention and control and mine local ventilation, be specially adapted to administer the methane accumulation of coal mining face upper corner angle, guarantee Safety of Coal Mine Production.
The methane accumulation of coal mining face upper corner angle is one of fundamental cause of colliery generation gas explosion accident, the methane accumulation of U type ventilation coal-face upper corner is the global problem that Coal Production often takes place and is difficult to administer, in the work of administering methane accumulation, because method is improper, it is improper particularly to equip, the serious accident that a lot of generation burning things which may cause a fire disaster cause gas explosion took place, and therefore, was studying both at home and abroad always and can effectively administer the equipment of coal-face upper corner methane accumulation.In recent years, in the method for ventilation of administering the methane accumulation of coal-face upper corner, have two classes to enjoy people's attention: a class is with no-spark (no electrical spark, no static spark, no friction spark) mining partial ventilator, another kind of is the distinguished and admirable booster of mining pulse, by retrieval, given priority to mining partial ventilator the beginning of the nineties abroad with no friction spark, for example French DV pneumatic booster of developing of series and the double dynamical booster of EST series wind-powered electricity generation, the WLP pneumatic booster of series of Poland's development and the double dynamical booster of WLEP series wind-powered electricity generation, the double dynamical local ventilation function of this wind-powered electricity generation is driven by pressure wind when ventilator has a power failure immediately, to guarantee that ventilator uninterruptedly turns round, avoid gas accident occurring because of ventilator has a power failure.The beginning of the nineties, coal academy of sciences Chongqing branch also succeeds in developing and presses the wind booster, it is by air motor, composition such as plastic impeller and silencing apparatus, to press the wind source that is used as power, no electrical spark danger, after fixing a silencer, noise descends significantly, succeeds in developing FSQD-18.5 type mining multifunctional booster in 99 years again, it is with German EST series, the booster of Poland WLEP series is similar, all be to have the wind-powered electricity generation dual power source, difference is that wind motor and impeller are not direct-connected mechanisms, but connects by clutch, during electric drive, wind motor disconnects voluntarily and not rotating, so the motoring resistance is little, the efficient height.More than the body of all booster all maintain static moving, the distinguished and admirable of generation all is axially permanent distinguished and admirable, be that wind direction, air quantity are constant basically, time to time change not, the no-spark performance of power source is by motor being taked flame proof or power source for pressing wind, no-spark performance own realizes, no-spark and the no static spark performance of moving friction are to realize by the material that changes impeller or interior cover, as using anti-electrostatic fire retardant engineering plastics or " Sparkless " aluminum alloy impeller, the interior cover of beryllium copper etc.
The distinguished and admirable right and wrong of pulse are permanent distinguished and admirable, distinguished and admirable speed is cyclically-varying in time, be that wind speed raise before this, descend then, raise again, descend again, so repeatedly, the more permanent distinguished and admirable high several times of this distinguished and admirable diffusion coefficient can make fresh distinguished and admirablely mix with gas consumingly, destroy methane accumulation state in the mine effectively, eliminate the methane accumulation in its effective range.At present, people such as the K.Z. Wu Shakefu of Moscow, Russia mining industry university professor and doctor Liao Guifa are in the research of carrying out distinguished and admirable theory of direct current (without spin) pulse and generating means thereof, to press wind or electrical actuation power, drives impeller produces distinguished and admirable, maintain static the opposite outlet air draft of air-out direction from two then, the open and close that hocket, it is distinguished and admirable to obtain DC pulse, but that its blower fan structure is not seen so far is open.
The objective of the invention is to design a kind of high safety reliability, distinguished and admirable EFFECTIVE RANGE is long, diffusion strength is high, produce the distinguished and admirable hydraulic, double rotary and pulsation type ventilator for local parts for mining use of dual rotary pulse, it can eliminate the methane accumulation in its effective range safely fast.
The objective of the invention is to realize by following technical solution: this hydraulic, double rotary and pulsation type ventilator for local parts for mining use comprises impeller rotary hydraulic motor, body rotary hydraulic motor, impeller, impeller chimney, swivel joint, protection cage and hydraulic control valve group.The employing pressure emulsified liquid is a power source.The impeller rotary hydraulic motor is fixed on the impeller chimney, connect drives impeller by axle, the rotary part of impeller chimney and swivel joint is fixed, swivel joint is fixed on the supporting frame, there are feed liquor pipeline and fluid pipeline to be connected on the swivel joint with the impeller rotary hydraulic motor, the body rotary hydraulic motor connects the rotary part of rotary driving joint by axle, thereby driving fan sweeps as hoop, the whole machine body outside is netted screw type protection cage, a protection cage part is netted protection, a part is the iron plate protection of spiral outlet, the hydraulic control valve group comprises two groups of Pressure Reducing Governor Valves, one-way valve, selector valve and connection pipe fitting are used for supplying with and control impeller rotary hydraulic motor and body rotary hydraulic motor power source and size thereof.
The present invention compared with prior art, be characterized in: 1. this device adopts pressure emulsified liquid aspect power, do not produce spark in itself, this liquid source that is used as power, better than the lubricity of water, the rustless property height, viscosity is big slightly, energy conversion efficiency is higher, and coal-face just has this pressure source, convenience, economic; 2. the distinguished and admirable of this equipment generation is that the dual rotary pulse is distinguished and admirable, it is compared to distinguished and admirable with stationary axle with non-rotating pulse is distinguished and admirable, it is long to have axial (vertically) EFFECTIVE RANGE, water down the diffusion coefficient height of gas, and hoop (laterally) sweeps adjustable-speed and have flexible discharging effect etc. to be suitable for administering the good characteristic of coal-face upper corner methane accumulation to the gas warehouse district; 3. netted screw type protection cage has not only improved the effect of pulse ventilation, and operating personnel's safety and health is had protective action.
