Abstract
The utility model discloses a kind of electric spraying device for tunnel coal dust, this device comprises down-hole supply channel, several electromagnetic valves, several arc arms, several fog-spray nozzles be arranged on arc arm, described down-hole supply channel is arranged on the sidewall in tunnel, described down-hole supply channel is uniformly distributed several arc arms, each arc arm is provided with an electromagnetic valve; Described arc arm is arranged on the top in tunnel, and radian mates with the radian at top, tunnel.The utility model be applicable to all mines install atomizing de-dusting tunnel in, explosion-proof solenoid valve as opening and closing automatically spraying main device, easy maintaining; By controlling the start-stop of lighting signal comprehensive protector power supply, the start-stop function of whole piece tunnel internal spraying can be realized.
Description
Technical field
The utility model belongs to plant engineering technical field, is specifically related to a kind of electric spraying device for tunnel coal dust.
Background technology
In prior art, underground coal mine is by carrying out unlatching spray valve manually, tunnel coal dust compared with hours artificial manually close down spray valve comparatively bother and due to tunnel long, closing spray time can be very long, causes a large amount of spraying trickle to be sprayed on roadway floor, causes roadway floor pucking.
Utility model content
In view of this, main purpose of the present utility model is to provide a kind of electric spraying device for tunnel coal dust.
For achieving the above object, the technical solution of the utility model is achieved in that
The utility model embodiment provides a kind of electric spraying device for tunnel coal dust, this device comprises down-hole supply channel, several electromagnetic valves, several arc arms, several fog-spray nozzles be arranged on arc arm, described down-hole supply channel is arranged on the sidewall in tunnel, described down-hole supply channel is uniformly distributed several arc arms, each arc arm is provided with an electromagnetic valve; Described arc arm is arranged on the top in tunnel, and radian mates with the radian at top, tunnel.
In such scheme, the power sources in parallel of several electromagnetic valves described is on the power supply of flame-proof mine lighting signal comprehensive protector.Compared with prior art, the beneficial effects of the utility model:
The utility model be applicable to all mines install atomizing de-dusting tunnel in, explosion-proof solenoid valve as opening and closing automatically spraying main device, easy maintaining; By controlling the start-stop of lighting signal comprehensive protector power supply, the start-stop function of whole piece tunnel internal spraying can be realized.
Accompanying drawing explanation
Fig. 1 provides a kind of structural representation of the electric spraying device for tunnel coal dust for the utility model embodiment.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model embodiment provides a kind of electric spraying device for tunnel coal dust, as shown in Figure 1, this device comprises down-hole supply channel 4, several electromagnetic valves 1, several arc arms 2, several fog-spray nozzles 3 be arranged on arc arm 2, described down-hole supply channel 4 is arranged on the sidewall in tunnel, described down-hole supply channel 4 is uniformly distributed several arc arms 2, each arc arm 2 is provided with an electromagnetic valve 1; Described arc arm 2 is arranged on the top in tunnel, and radian mates with the radian at top, tunnel.
The power sources in parallel of several electromagnetic valves 1 described is on the power supply of flame-proof mine lighting signal comprehensive protector.
Described down-hole supply channel 4 pressure of supply water is greater than 0.8MPa, when coal dust is larger, opens illumination sign comprehensive protection device power supply and can realize opening spraying function, when coal dust is less, closes illumination sign comprehensive protection device power supply and can realize closing spraying function.
The above, be only preferred embodiment of the present utility model, is not intended to limit protection domain of the present utility model.
