Description
Technical field
This utility model relates to a kind of mine safety device, specifically a kind of mining portable gas draw-off pump station.
Background technology
In process of coal mining, owing to coal seam being contained substantial amounts of methane gas, disaster of easily blasting, bring considerable risk to exploitation.For ensureing the personal safety of Safety of Coal Mine Production and worker, preventing Gas Disaster, we are badly in need of designing a kind of safety equipment in process of coal mining so that it is can directly go deep into scene and directly draw out methane, and by pipeline, methane gas is transported to ground and is used, change harmful to treasure.
Summary of the invention
The purpose of this utility model is to solve above-mentioned problems of the prior art, and provides a kind of mining portable gas draw-off pump station.
This utility model is achieved by the following technical solution:
A kind of mining portable gas draw-off pump station, including chassis, and it is located at the fire-proof motor in chassis, decelerator, water ring vacuum pump and moisture trap, the output shaft of fire-proof motor is connected with water ring vacuum pump by decelerator, and Water-ring vacuum delivery side of pump is connected with the entrance of moisture trap by exhaust pipe.
Operation principle of the present utility model is that fire-proof motor drives water ring vacuum pump to rotate, and forms negative, positive pressure chamber in the pump housing, and carry out inhaling, exhaust work.Moisture trap is used for water ring vacuum pump exhaust port side, owing to water ring vacuum pump forms annular seal space air-breathing by water ring, therefore containing a certain amount of moisture in air vent gas, accordingly, it would be desirable to water is separated from gas.Moisture trap is constant by its internal control linkage guaranteed water level, reaches automatic draining function.
Further; also include vacuum electromagnetic starter, microswitch, long-range cutoff instrument, methane transducer, cut off the water power-off protection apparatus and orifice flowmeter; wherein; vacuum electromagnetic starter is connected with power input and motor wiring chamber respectively; long-range cutoff instrument is connected with vacuum electromagnetic starter by microswitch; methane transducer and power-off protection apparatus of cutting off the water are connected with long-range cutoff instrument respectively, and orifice flowmeter is installed in exhaust pipe.
Long-range cutoff instrument and methane transducer composition gas exceeding limit power-off protection apparatus, for monitoring movable pump station working environment methane concentration in real time, when methane concentration exceedes warning line (1%), methane transducer sends out sound and light alarm；When methane concentration is more than 1.5%, long-range cutoff instrument controls vacuum electromagnetic starter power-off by control circuit, to guarantee the security reliability that gas pump station works.
When supply channel is cut off the water supply, power-off protection apparatus of cutting off the water starts, microswitch action, controls pumping plant automatic power-off shutdown by long-range cutoff instrument, thus reaching protection purpose.
Orifice flowmeter, in order to measure the gas flow in exhaust pipe, when gas is by the road by orifice plate, produces pressure reduction, can calculate the flow of gas in pipeline by pressure reduction in orifice plate both sides.
Popularizing application prospect of the present utility model is as follows: 1) owing to its volume is little, mobile flexibly, those are not possessed and set up ground gas drainage system or the remote mine of working, the motility of available movable gas pumping station, carry out relay-type extraction；2) owing to its investment is little, instant effect, there is good safety and economy benefit, in local, small coal mines there is stronger captivation；3) due to sudden problem may result in ground gas draw-off pump station can not run well time, now can adopt movable pump station that down-hole main region carries out gas drainage under suction, ensure mine safety production；4) for gas scientific research and testing, draw out methane before pumping plant setting up ground, carry out down-hole examination with movable pump station and take out, test determine best drainage method and gas drainage parameter, reliable foundation is provided, it is to avoid blind investment causes waste for setting up permanent ground pump station drainage system.
The use of this utility model mining portable gas draw-off pump station, transfinite for highly gassy mine improvement local gas and provide theory and practice knowledge, and gas drainage under suction carries out in closing pipe line, the aspects such as the safety in production founded a capital in ore deposit, safety management play a significant role, it is also equipped with following advantage: alleviate labor strength simultaneously, is conducive to safety in production, saves lot of materials consumption, promote gas control general layout, be widely used.
