Technical Field

The utility model belongs to the technical field of coal mine equipment, a spraying of stopping agent is related to, specifically is a mining removal stops agent sprinkler.

Background

The existing spraying stopping agent system for the coal mine is complex in structure, multiple in pipelines and large in daily management and maintenance workload, so that messy pipelines affect the tidiness of the working environment, the labor intensity of workers is high, and the normal production of a fully mechanized coal mining face is affected.

Disclosure of Invention

The utility model aims to solve the problem that the current spraying hinders agent system architecture is complicated among the background art, and the pipeline is numerous, and daily management maintains that work load is big, provide a mining portable hinders agent sprinkler.

The technical proposal of the utility model for solving the technical problem is that: a movable stopping agent spraying device for a mine comprises a stopping agent liquid box and a stopping pump, wherein the stopping agent liquid box is arranged on a movable mine car and is provided with a water supply pipeline and a liquid outlet pipeline, a first flow meter is arranged on the water supply pipeline, the free end of the liquid outlet pipeline is connected to a liquid inlet of the stopping pump, a liquid outlet of the stopping pump is connected with a spray gun or an atomizing spray head through a liquid discharge rubber pipe, a pressure gauge and a second flow meter are arranged on the liquid discharge rubber pipe, valves are arranged on the water supply pipeline and the liquid outlet pipeline, and valves are respectively arranged on the liquid discharge rubber pipes at two ends of the pressure gauge and the flow meter; the inhibition liquid box comprises a magnesium chloride solution with the concentration of 15-20%.

A mining portable stopping agent sprinkler's operation method: one person controls a spray gun or an atomizing spray head, one person drags a liquid discharge rubber pipe, one person stirs a stopping agent in a stopping liquid tank to prevent precipitation, a stope face is covered with cloth before spraying the stopping agent, so that the stopping agent is prevented from damaging electromechanical equipment, after the equipment is checked, clear water and magnesium chloride in a certain proportion are added into the stopping agent liquid tank, and then a magnesium chloride solution with the concentration of 15-20% is stirred and prepared; before the spraying work starts, a switch of the spray gun or the atomizing nozzle is opened to enable the spray gun or the atomizing nozzle to be in a normally open state; starting the inhibition pump from low pressure, adjusting the pressure of the inhibition pump to the required pressure after the system operates normally, starting normal spraying work, and spraying to the goaf from the space between the last row of pillars of the fully mechanized mining face, wherein the spraying flow is not less than 35L/min; spraying is carried out once a day during normal stoping, and the arrangement is carried out in an overhaul class, if the conditions of production halt, fault passing, ending and the like are met, the spraying frequency must be increased for a goaf. And after spraying is finished, filling clear water into the stopping agent liquid tank, and cleaning the stopping pump, the liquid outlet pipeline, the liquid discharge rubber tube, the spray gun or the atomizing nozzle. After cleaning, a pressure regulating handle of the inhibition pump is pulled to a pressure relief position, and the machine can be stopped after the pressure is reduced; the water adding amount can be obtained through the first flowmeter, so that the proportion of the magnesium chloride solution with required concentration can be easily realized, the spraying flow of the stopping agent and the amount of the stopping agent can be accurately known through the second flowmeter, the pressure gauge can detect out the spraying pressure value of the stopping agent, and the accurate control is achieved.

The utility model has the advantages that: the volume is small, the weight is light, and the transportation and the carrying are convenient; the device can be flexibly adjusted according to the situation of a field working face, can directly spray the stopping agent to residual coal by using a spray gun, and can also be used for spraying by using an atomizing nozzle; the device is suitable for working conditions and environments with poor underground natural conditions and inconvenient operation of equipment and personnel; the labor intensity of workers can be reduced, and the management and labor cost is saved.
