Abstract
The utility model discloses an automatic gas-water spraying device for an underground cannon area, wherein a gas-water spray head and an acoustic-control electric switch are installed at the cannon area, the gas-water spray head is connected onto a dustproof water pipe and a pressure ventilation pipe, a water-supplying electromagnetic valve and a wind-supplying electromagnetic valve are respectively arranged on the dustproof water pipe and the pressure ventilation pipe, the dustproof water pipe is then communicated with a metering pump for providing a dust capturing agent, and the acoustic-control electric switch is electrically connected with the water-supplying electromagnetic valve, the wind-supplying electromagnetic valve and a metering-pump electric switch. During underground blasting, shock-wave acoustic-pressure signals generated by blasting are transferred to the acoustic-control electric switch, the acoustic-control electric switch is switched on to supply power for the metering-pump electric switch, the water-supplying electromagnetic valve and the wind-supplying electromagnetic valve, the metering pump works, the water-supplying electromagnetic valve and the wind-supplying electromagnetic valve are simultaneously turned on, and pressure wind and pressure water which contains the dust capturing agent are sprayed out of the gas-water spray head to form a gas-water mixture, so that the whole cross section of a laneway is closed to achieve the purpose of dust removal.
Description
Technical field
The utility model relates to dust suppression in mine equipment.
Background technology
When down-hole large section roadway explosion at present, produce a large amount of dust and toxic and harmful, bring great threat to site operation personal security, purling enters other tunnels, down-hole with the wind simultaneously, and therefore after explosion, dedusting immediately, smoke abatement are the keys that solves down-hole toxic and harmful.
Summary of the invention
The utility model, for addressing the above problem, designs big gun district, a kind of down-hole air water automatic sprayer.
Big gun district, a kind of down-hole air water automatic sprayer, it is characterized in that, Ta Shibao district is provided with air water fog-spray nozzle and acoustic control electric switch, air water fog-spray nozzle is connected on dustproof water pipe and pressure ventilation pipe, on dustproof water pipe and pressure ventilation pipe, be respectively equipped with water supply electromagnetic valve and air feed electromagnetic valve, dustproof water pipe is connected with the measuring pump that dust agent for capturing is provided again, and acoustic control electric switch is electrically connected with water supply electromagnetic valve, air feed electromagnetic valve and measuring pump electric switch.
According to operating principle, explanation the utility model has the advantages that below: in the time of underground blasting, the shockwave sound pressures signal that explosion produces is delivered to acoustic control electric switch, acoustic control electric switch is connected, give measuring pump electric switch, water supply electromagnetic valve and air feed solenoid valve, measuring pump work, water supply electromagnetic valve and air feed electromagnetic valve are opened simultaneously, pressure wind and the press water that contains dust agent for capturing spray from air water fog-spray nozzle, form air-water mixture, seal whole drift section, form a dust agent for capturing air water spraying curtain, minimum dust be captured agent merge water droplets and with blasting fume in NO
2, NO, CO
2formation nitric acid, carbonic acid are deposited in roadway floor, eliminate the infringement to human body, after time delay spraying official hour, automatically stop.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
In figure, 1-air water fog-spray nozzle, the 2-water pipe that prevents dust, 3-pressure ventilation pipe, 4-water supply electromagnetic valve, 5-air feed electromagnetic valve, 6-measuring pump, 7-measuring pump electric switch, 8-acoustic control electric switch.
Detailed description of the invention
Big gun district, down-hole air water automatic sprayer as shown in Figure 1, Ta Shibao district is provided with air water fog-spray nozzle 1 and acoustic control electric switch 8, air water fog-spray nozzle 1 is connected on dustproof water pipe 2 and pressure ventilation pipe 3, on dustproof water pipe 2 and 3, be respectively equipped with water supply electromagnetic valve 4 and air feed electromagnetic valve 5, dustproof water pipe 2 again with 6 connecting that dust agent for capturing is provided, acoustic control electric switch 8 is electrically connected with water supply electromagnetic valve 4, air feed electromagnetic valve 5 and measuring pump electric switch 7.
