Abstract
The utility model discloses an extraction device of mine gas, which comprises an electric control box, a gas instrument, a sensor and a gas discharge mechanism, wherein the gas instrument stretches into the deep of a mine, the gas discharge mechanism comprises a pneumatic injector pump, a transfer piping, a gas storage tank and an air compressor which is connected with the electric control box, the pneumatic injector pump stretches into the sides of the gas instrument and the sensor, the transfer piping is communicated with the pneumatic injector pump, compressed air piping which are communicated are arranged between the pneumatic injector pump and the gas storage tank, and the air compressor is connected with the gas storage tank. The extraction device of mine gas using the structure can greatly increase the speed of extracting gas, increases the safety factor of a mine, and has convenient installment and use.
Description
Technical field
The utility model relates to a kind of draw-out device of mine gas.
Background technology
Mine must use the draw-out device of mine gas down at present, to guarantee that gas density under the mine is in safe range, the draw-out device of existing mine gas comprises electric control box, extend into the gas instrument of mine depths and sensor, the gas output mechanism, after the gas density under the mine reaches or surpasses permissible value, electric control box starts gas and extracts mechanism, but the speed of the draw-out device gas extraction of present mine gas is slower, and the safety factor of mine is lower.
The utility model content
Technical problem to be solved in the utility model is: a kind of draw-out device of mine gas is provided, and the draw-out device of this kind mine gas can increase substantially the speed of gas extraction, thereby can improve the safety factor of mine.
Solve this technical problem, the technical solution of the utility model is: a kind of draw-out device of mine gas, comprise electric control box, extend into the gas instrument of mine depths and sensor, the gas output mechanism, described gas output mechanism comprises Pneumatic injection pump, conveyance conduit, gasholder and is connected to the air compressor machine of electric control box, described Pneumatic injection pump extend into gas instrument and sensor side, conveyance conduit is communicated with Pneumatic injection pump, have the compressed air piping that is communicated with between Pneumatic injection pump and the gasholder, described air compressor machine links to each other with gasholder.
The draw-out device of the utility model mine gas adopts such structure, can increase substantially the speed of gas extraction, has improved the safety factor of mine, and is easy to install.
Description of drawings
Below in conjunction with accompanying drawing the draw-out device of the utility model mine gas is done explanation in further detail;
Fig. 1 is the draw-out device structural representation of the utility model mine gas;
In Fig. 1,1, air compressor machine; 2, gasholder; 3, compressed air piping; 4, conveyance conduit; 5, cable; 6, electric control box; 7, gas instrument and sensor; 8, Pneumatic injection pump; 9, mine.
The specific embodiment
As shown in Figure 1, a kind of draw-out device of mine gas comprises Pneumatic injection pump 8, conveyance conduit 4, gasholder 2, air compressor machine 1, electric control box 6 and gas instrument and sensor 7, Pneumatic injection pump 8 extend into mine 9 depths, conveyance conduit 4 is communicated with Pneumatic injection pump 8, Pneumatic injection pump 8 is communicated with by compressed air piping 3 with gasholder 2, air compressor machine 1 links to each other with gasholder 2, air compressor machine 1 is connected to electric control box 6 by cable, gas instrument and sensor extend into the side of Pneumatic injection pump, gas instrument and sensor 7 are wired to electric control box 6, electric control box 6, gasholder 2 and air compressor machine 1 are arranged on the ground of mine.The structure of Pneumatic injection pump is on the books on the CN1912399 at the Chinese patent publication number, this kind Pneumatic injection pump comprises suction pipe, the pump housing, efferent duct, be the mass transport direction by suction pipe to the order of efferent duct on the pump housing, on the same axis between suction pipe and the efferent duct, nozzle overcoat, mixing tube, diffusion pressurizing pipe are set, be enclosed within that nozzle on the suction pipe is enclosed between the end of inner conical surface and suction pipe outward, the nozzle ring of shape taper, the shrinkage direction of its taper points to efferent duct by suction pipe, puts to establish air jet pipe outside nozzle.
Open electric control box 6, draw the gas density that is contained under the mine, after the gas density under the mine reaches or surpasses permissible value, electric control box starts air compressor machine, compressed air enters Pneumatic injection pump, with gas and water by conveyance conduit row from, the pit zone gas density that can guarantee gas instrument and sensor 7 places is in safe range.Use Pneumatic injection pump 8, owing to Pneumatic injection pump 8 both movement-less part, also non-transformer only has sensor to use light current, avoids producing electric spark, and is safe in utilization; Pneumatic injection pump places the mine depths, and by pneumatically operated, and air compressor machine and electric control box can be arranged in the grass top, can realize far distance automatic controlling, handling safety; Pneumatic injection pump when work, stone, water, block and gas can by conveyance conduit fast row from, improved the safety factor of mine.
