The utility model further defines the technical scheme that:

preferably, the dust fall mechanism comprises a branch pipe and a plurality of spray heads, wherein the branch pipe is arranged on the main pipe, and the spray heads are uniformly arranged on the branch pipe.

Preferably, the distance between the branch pipe and the bottom wall of the mine tunnel is 3m-5m.

Preferably, a gate valve is arranged on the main pipe, a pressure gauge is arranged behind the gate valve, a pressure reducing valve is arranged behind the pressure gauge, and the gate valve, the pressure gauge and the pressure reducing valve are all positioned in front of the branch pipe.

Preferably, the branch pipe is positioned in front of the outlet of the chamber body.

In summary, the present application includes the following beneficial technical effects: the dust content of the polluted air can be reduced by the water curtain sprayed out of the spray head, when the polluted air passes through the chamber body, the air in the chamber body can be taken out by utilizing the pressure difference caused by the air speed, the polluted air is not required to form convection into the chamber body, so that the dust in the distribution chamber can be greatly reduced, and after the water curtain sprayed out of the water curtain falls into a mine channel, the water curtain can be gradually dried under the action of the air flow, so that the mine channel is not worried about being in a wet state for a long time, and the normal passing of workers is influenced.

Description of the embodiments

The present application is described in further detail below in conjunction with figures 1-3.

The embodiment of the application discloses dust fall device of underground distribution chamber, refer to fig. 1, including mine tunnel 1, main pipe 2 and chamber body 3, chamber body 3 is installed in mine tunnel 1 one side, main pipe 2 is installed in mine tunnel 1 lateral wall, install gate valve 8 on main pipe 2, install manometer 9 behind gate valve 8, install relief pressure valve 10 behind manometer 9, gate valve 8, manometer 9 and relief pressure valve 10 all are located branch pipe 6 the place ahead, the pressure regulating scope of relief pressure valve 10 should be controlled at 0.5-1.0MPa, if the pressure is too high, shower nozzle 7 is worn out easily, the water spray volume is big, cause main ventilation blower humidity to increase, influence staff's normal work;

referring to fig. 2, a dust fall mechanism is arranged on a main pipe 2, the dust fall mechanism comprises a branch pipe 6 and a plurality of spray heads 7, the branch pipe 6 is arranged on the main pipe 2, the distance between the branch pipe 6 and the bottom wall of a mine pipeline 1 is 3m-5m, the branch pipe 6 and the spray heads 7 at the height cannot influence the normal work of workers, and the branch pipe 6 is a DN25 water pipe;

the spray heads 7 are uniformly arranged on the branch pipes 6, the branch pipes 6 are positioned in front of the outlets 4 of the chamber body 3, specifically, the branch pipes 6 and the spray heads 7 are positioned 50-80 meters away from the main ventilator (generally at half the distance from a roadway opening to the main ventilator according to the length of a roadway opening to the main ventilator), and the chamber body 3 and the main ventilator are positioned for a long time, so that the branch pipes 6 are also positioned in front of the chamber body 3;
