Description of drawings
Fig. 1 is the coal winning machine gas-water mixing external spraying system schematic that the embodiment of the present invention provides.
The specific embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.
As shown in Figure 1, coal winning machine gas-water mixing external spraying of the present invention system mainly comprises the water system that press water is provided, the air supply system that pressed gas is provided, the atomizing component that has been connected with air supply system with water system respectively.
Water system be pressure water source foremost.Pressure water source will be pressurizeed by the water source of outside access, makes it have certain pressure.Adopt pumping plant as pressure water source in the present invention, provide press water by pumping plant to water system.Press water filters by strainer 2 through after stop valve 1, filtering impurity wherein.Then, press water flows into reducing valve 3, and reducing valve 3 reduces to inlet pressure the outlet pressure of a certain needs by regulating, and relies on the energy of medium itself, makes outlet pressure automatically keep stable.The press water of adjusting through excess pressure flows into cutting motor 14.Cutting motor 14 provides power source for the driving of coal-winning machine, and powerful cutting motor needs water cooling.In order to improve the service efficiency of mine water, in the present invention, the cooling water of cutting motor 14 is provided by press water, and namely pressure flow flows out after the cooling recirculation system of cutting motor 14 again, is used for dedusting, can save the down-hole water like this on to greatest extent.In order to guarantee that the press water pressure that flows out cutting motor 14 satisfies the demand, can on the pressure water line that flows out cutting motor 14, liquid flooding valve 4 be set.Liquid flooding valve 4 has level pressure overflow effect, when system pressure increases, traffic demand is reduced, and this moment, 4 unlatchings of liquid flooding valve, can make unnecessary flow overflow back, guarantees the overflow valve inlet pressure, namely pumps the constant pressure of saliva.In addition, in order to understand at any time the hydraulic pressure of water system outflow end, water pressure gauge 5 can be set at the end of water system.
Cooling system can be in water system any part access, as the top with the end access coal-winning machine cooling system of stop valve, and the end of coal-winning machine cooling system is connected with the top of liquid flooding valve.
Air supply system be pressure gas source foremost.Pressure gas source is used for providing the gas with certain pressure to air supply system.Pressure gas source in the present invention comprises gasholder and air compressor machine.Air compressor driving motor 8 drives air compressor machine 9 and produces Compressed Gas, and Compressed Gas is saved in gasholder 10.In order to grasp the state of gas in gasholder 10, can connect gas gauge 12 and gas overflow valve 11 on gasholder 10.Be to guarantee the pressure of dedusting gas, after gas flows out from gasholder 10, can use the air pressure-adjusting valve 13 that is connected to the air supply system rear end to carry out pressure and regulate.
After this, the press water that flows out from water system and flow out the gas with specified pressure from air supply system and enter respectively atomizing component and mix.Atomizing component comprises spraying piece 6 and the nozzle for atomizing water with air 7 that is connected on spraying piece 6.The quantity of nozzle for atomizing water with air 7 can be according to using on-the-spot needs to determine.Press water and pressed gas arrive respectively liquid inlet and the air intake of nozzle for atomizing water with air 7 under the effect of spraying piece 6, press water and pressed gas mix in air cap and the liquid cap inside cavity of nozzle for atomizing water with air 7, by the breaking and clash into atomized spraying satisfactory for result of air, then through nozzle for atomizing water with air 7 ejections.
Due to ejection from steam atomizing nozzle 7 be all even fine and closely woven water smoke by atomizing, therefore have stronger dust removing effects than existing down-hole water spray system.
Be provided with respectively water pressure gauge 5 and gas gauge 12 in water system of the present invention and air supply system, can understand at any time the pressure condition of two systematic pipeline inside, regulate at any time, formed from adjusting being detected again to the operation with closed ring pattern that detects, the precision that the system that guaranteed regulates.
Simultaneously, in coal winning machine gas-water mixing external spraying of the present invention system, be provided with reducing valve 3, liquid flooding valve 4 in water system; Simultaneously be provided with gas overflow valve 11 and air pressure-adjusting valve 13 in air supply system, so just can regulate at any time the hydraulic pressure of press water and the air pressure of air supply system according to the needs of down-hole coal excavation operation, and then control the fogging degree of spraying.On the other hand, owing to being provided with air supply system in the present invention, can make that the air water spray velocity is high, far firing range, depositing dust efficient be high; Under the effect of air supply system high pressure, improve the injection air quantity, make nozzle be difficult for stopping up.One cover coal winning machine gas-water mixed aerosol of the present invention system can be set on every coal-winning machine.The quantity of spraying piece and nozzle for atomizing water with air in use is set according to the concrete needs of volume, cut scope and the underground mining of coal-winning machine, makes it cover the dust generation area fully.
The above is only preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
