In order to achieve the purpose, the gas-film totally-enclosed coal yard gas-locking coal unloading ditch of the utility model comprises a gas-locking coal unloading ditch body, an underground belt conveyor and a gas-film totally-enclosed coal yard;
The gas-locking coal unloading ditch is internally provided with an automobile coal unloader, an impeller coal feeder and an underground coal hopper, a coal unloading grid is arranged at the opening at the top of the underground coal hopper, the automobile coal unloader is matched with a coal conveying automobile to convey coal in the coal conveying automobile into the underground coal hopper, the impeller coal feeder is matched with the outlet at the bottom of the underground coal hopper to uniformly distribute raw coal in the underground coal hopper to one side of an underground belt conveyor, and the other side of the underground belt conveyor penetrates through a gas-locking valve on a gas film totally-enclosed coal yard to be matched with a coal feeding system of a bucket wheel machine in the gas film totally-enclosed coal yard.
the gas-locking coal unloading ditch is internally provided with an automobile unloading position for parking a coal conveying automobile.
The air-locking coal unloading ditch body is provided with a worker access passage, an emergency evacuation passage and a plurality of escape doors.
A fire-fighting system, a spraying dust-settling system, a pollutant monitoring system, a control system and an illuminating system are arranged in the air-locking coal unloading ditch.
The utility model discloses following beneficial effect has:
The utility model discloses a totally closed coal yard of gas film lock gas coal unloading ditch when concrete operation, the impeller feeder cooperatees with the bottom export of underground coal scuttle and evenly distributes the raw coal in the underground coal scuttle to one side of underground belt conveyor, the opposite side of underground belt conveyor passes the lock gas valve on the totally closed coal yard of gas film and cooperatees with the last coal system of bucket wheel machine in the totally closed coal yard of gas film, in operation, totally closed coal yard of gas film and lock gas coal unloading ditch body independent layout, and adopt the enclosed construction, carry the car coal unloading to totally closed coal yard of gas film through underground belt conveyor, solved the too high problem of dust concentration that the car comes the coal and directly unloads the coal and cause in main coal yard space, the gas tightness of totally closed coal yard of gas film in the coal conveying process has the advantages such as construction convenience and construction cycle are short, satisfy the totally closed requirement of coal unloading ditch and the gas tightness requirement of gas film coal yard simultaneously, the device is convenient to operate, economical and practical, is suitable for closed transformation of the automobile coal unloading ditch of the gas film totally-closed coal yard, and has good economic and environmental benefits when being popularized in a thermal power plant.
