Abstract
The invention discloses an extracting device for mine gas, comprising an electric cabinet, a gas meter, a sensor and a gas discharging mechanism, wherein the gas meter and the sensor can extend into the deep part of a mine. The gas discharging mechanism comprises a pneumatic jet pump, a conveying pipeline, an air storage tank and an air compressor connected with the electric cabinet, wherein the pneumatic jet pump extends to the sides of the gas meter and the sensor, the conveying pipeline is communicated with the pneumatic jet pump, a communicated compressed air pipeline is arranged between the pneumatic jet pump and the air storage tank, and the air compressor is connected with the air storage tank. By adopting the structure, the extracting device for mine gas can greatly improve the speed of extracting the gas and the safety factor of the mine, and is convenient to installed and use.
Description
Technical field
The present invention 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 the gas output 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.
Summary of the invention
Technical problem to be solved by this invention 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, technical scheme of the present invention 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 a kind of mine gas of the present invention 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 a kind of mine gas of the present invention is done explanation in further detail;
Fig. 1 is the draw-out device structural representation of a kind of mine gas of the present invention;
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.
