Abstract
The utility model provides a novel air pressure type resistance pump device which aims to avoid fire caused by coal spontaneous combustion in coal mine underground goaf. The device is utilized to spray and inject stopping agent solution into the goaf to form aerial fog falling on the surface of float coal to form a protection film, and coal spontaneous combustion is effectively stopped. The device is composed of a stopping agent material barrel, a feeding port, an air pressing pipe regulating valve, a stopping agent regulating valve, a high pressure air bag, a discharging pipe and a base frame. Compared with a motor type resistance pump, the device also achieves the effect of spraying and injecting the stopping agent solution of the motor type resistance pump. Water can be used to replace the stopping agent solution to achieve the effect of dust prevention on a backstopping work face or an excavating roadway. Air of the air pressing pipe is utilized to serve as power, so that accidents of coal mine underground electromechanical devices are reduced.
Description
Technical field
The utility model belongs to the fire prevention and the dustproof field of stope working surface of coal mines or digging laneway, a kind of specifically novel wind pressure type resistanceization pump installation.
Background technology
At present, in the actual mining process, cause fire under the coal mine in order to prevent the goaf from spontaneous combustionof coal taking place.We generally adopt electrodynamic type resistanceization pump, go into the spray of retardant solution to form the surface that aerosol drops to float coal in the goaf, form diaphragm, have stoped the spontaneous combustion of coal effectively.But, too much use electromechanical equipment to have certain drawback under the coal mine, and the power of electrodynamic type resistanceization pump is to use motor, is easy to cause the generation of dynamo-electric accident.Electromechanical equipment has an accident under the coal mine in order to reduce, and we have researched and developed a kind of novel wind pressure type resistanceization pump installation.
Summary of the invention
The utility model provides a kind of novel wind pressure type resistanceization pump installation, mainly utilizes pressure fan as power, goes into the spray of retardant solution to form the surface that aerosol drops to float coal in the goaf, forms diaphragm, has stoped the effect of spontaneous combustionof coal effectively.Having reduced electromechanical equipment has an accident.
The utility model is achieved in that this device has comprised retardant charging basket, charge door, pressure ventilation pipe control valve, retardant control valve, high pressure bellows chamber, discharge nozzle and mounting.Iron sheet is processed the retardant charging basket; On the retardant charging basket, reserve charge door, the passage below the retardant charging basket be connected the high pressure bellows chamber, the retardant control valve by at the middle part of passage; The high pressure bellows chamber is connected with pressure ventilation pipe, discharge nozzle, by last mounting.Then, the retardant charging basket adds retardant solution.
The beneficial effect of the utility model is: simple in structure, light and handy, and provide power to avoid the generation of electromechanical equipment accident without motor.Reached the effect of electrodynamic type resistanceization pump spray retardant solution equally.
Description of drawings
Be described further below in conjunction with accompanying drawing
It among the figure structural representation of the utility model
Among the figure 1, retardant charging basket 2, charge door 3, passage, 4, retardant control valve 5, airduct control valve 6, blast pipe 7, high pressure bellows chamber 8, pressure ventilation pipe 9, discharge nozzle 10, mounting 11, retardant solution
The specific embodiment
Iron sheet is processed retardant charging basket 1; On the retardant charging basket, reserve charge door 2; Passage 3 below the retardant charging basket be connected high pressure bellows chamber 7, by at the middle part of passage 3, high pressure bellows chamber 7 is connected with pressure ventilation pipe 8, discharge nozzle 9 retardant control valve 4; By last mounting 10, add retardant solution 11 then.
During use, after earlier pressure ventilation pipe 8 and blast pipe 6 being connected.Through charge door 2, pour retardant solution 11 in the retardant charging basket 1 into.Open airduct control valve 5 and open retardant control valve 4 again, press the power of wind to go into discharge nozzle 9 to 11 sprays of retardant solution through high pressure bellows chamber 7.Then, go into 11 sprays of retardant solution in the goaf through discharge nozzle 9.Like the quality of retardant solution spray effect, can use airduct control valve 5 and retardant solution control valve 4, regulate the contrast of wind and retardant solution, reached the effect of electrodynamic type resistanceization pump spray retardant solution equally.Can also make water replace retardant solution in stope or the effect of digging laneway dustproof.
