Abstract
The utility model discloses a mine coal explosion automatic spray device, which can effectively reduce the dust and avoid the possible accidents caused by coal dust explosion. The device comprises a micro-vibration sensor (1), a controller (2), an electric ball valve (3) and a spray water curtain (6). The micro-vibration sensor (1) and the electric ball valve (3) are connected with the controller(2) through electric wires. A water supply pipe (5) and a water outlet pipe (4) are arranged on the electric ball valve (3). The spray water curtain (6) is connected with the water outlet pipe (4). The device is mainly used for coal mine under-well dust reduction and can avoid coal dust explosion.
Description
Technical field
The utility model relates to the quick-fried automatic sprayer of a kind of mine coal.
Background technology
Coal is quick-fried to be a kind of dynamic disaster of serious threat Safety of Coal Mine Production, has notable features such as sudden, instantaneous vibratility and considerable damage.Coal breaks out to be gushed out mine gas and produces a large amount of coal dusts when giving birth to, might cause the gas and dust explosion accident.Coal is quick-fried to be because the huge rock in down-hole falls suddenly, sharp pounding takes place and the coal dust that causes flies upward.When coal dust concentration reaches blast when critical, run into naked light and electrostatic spark, just can cause dust explosion accident, its extent of injury is not second to gas explosion.Coal-dust explosion frequently takes place in China's coal-mine, causes great casualties and property loss.Along with the continuous increase of the pit mining degree of depth, the deep mining impact manifests very obvious in recent years, and the quick-fried control of coal has become the common key subjects of paying close attention in the Safety of Coal Mine Production.Spray outfit such as existing down-hole is light-operated, infrared rays, acoustic control can not more can not prevent the generation of dust explosion accident at coal control spraying of quick-fried moment facility.
Summary of the invention
The coal dust that how to prevent the quick-fried generation of coal at home flies upward, and still is a technological gap at present.Artificial this difficult problem that solves of application has designed the quick-fried automatic sprayer of the utility model mine coal, the generation of dust explosion accident when it can prevent that coal is quick-fried.
The utility model is made up of little vibration sensor, controller, electrical ball valve and spraying water curtain, and a pair of little vibration sensor and electrical ball valve are connected on the controller by electric wire, and electrical ball valve is provided with water supply line and outlet conduit, and the spraying water curtain connects outlet conduit.
The utility model has following beneficial effect:
1, can monitor the quick-fried generation of coal automatically, open atomization mechanism, reach depositing dust and the purpose that prevents coal-dust explosion in the moment that coal is quick-fried.
2, volume is little, and is multiple functional, and the automaticity height is installed simply.
3, small investment, cheap for manufacturing cost, be convenient to promote the use of in coal mining enterprise.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: little vibration sensor 1, controller 2, electrical ball valve 3, outlet conduit 4, water supply line 5, spraying water curtain 6.
The specific embodiment
By accompanying drawing as can be known: the utility model is made up of little vibration sensor 1, controller 2, electrical ball valve 3 and spraying water curtain 6, a pair of little vibration sensor 1 and electrical ball valve 3 are connected on the controller 2 by electric wire, electrical ball valve 3 is provided with water supply line 5 and outlet conduit 4, and spraying water curtain 6 connects outlet conduit 4.
Use the utility model, the 127V power connection controller 2 of down-hole, feed pipe 5 is connected water sources, monitor a vibration source simultaneously by two that are installed in diverse location little vibration sensors 1 after, transmit signals to controller 2, after differentiating that its energy reaches setting value, controller 2 sends instruction, and control electrical ball valve 3 is opened, and water under high pressure is delivered to spraying water curtain 6 through electrical ball valve 3 and outlet conduit 4, form dustproof water smoke, pounce on and catch because the coal dust of the quick-fried generation of coal.
