Abstract
The utility model discloses a dust control device of a positive pressure spiral air curtain. The dust control device is used for limiting dust diffusion generated by underground coal mine production. Through the adopted technical scheme, crossed supports (4) are arranged on the left side and the right side of a cylindrical frame (1); bearing seats (5) are arranged at the central parts of the crossed supports (4) on the two sides; a rotating shaft (3) is matched with bearings in the bearing seats (5); a spiral impeller (2) is fixed on the rotating shaft (3). Unlimited dust flying in an underground excavating face can be controlled, dust is conveniently collected in an inlet of a dust collector in a concentrated mode, and the device is beneficial to the protection of underground environment and the health of workers.
Description
Technical field
The utility model relates to a kind of positive-pressure spiral air curtain dust control device.
Background technology
At present, a large amount of dusty gas that fully mechanized workface produces in producing under coal mine, workman sucks its health of infringement, is discharged into contaminated environment in air.
Summary of the invention
The technical problems to be solved in the utility model is, provide a kind of can be by dust Control in desired face, positive-pressure spiral air curtain dust control device.
For solving the problems of the technologies described above, the arranged on left and right sides of cylinder shape frame of the present utility model is provided with cross bracket, and bearing support is located at the centre of the cross bracket of both sides, the bearing fit in turning cylinder and bearing support, and helical runner is fixed on turning cylinder.
Adopt the utility model, can control unconfined dust from flying in used on down-hole mining surface, be convenient to concentrate the entrance that dust is sucked to deduster, be conducive to the healthy of the environmental protection of down-hole and workman.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
In figure: cylinder shape frame 1, helical runner 2, turning cylinder 3, cross bracket 4, bearing support 5.
The specific embodiment
From accompanying drawing: the arranged on left and right sides of cylinder shape frame 1 of the present utility model is provided with cross bracket 4, and bearing support 5 is located at the centre of the cross bracket 4 of both sides, the bearing fit in turning cylinder 3 and bearing support 5, helical runner 2 is fixed on turning cylinder 3.
Use the utility model, the right-hand member of this device is connected on the steel ring sleeve of the positive pressure wind pipe termination of using down-hole, then hangs up.Malleation straight line is distinguished and admirable to be blown on helical runner 2, and this helical runner 2 will automatic rotation, and malleation straight line is distinguished and admirable will change the flow direction, sees through cylinder shape frame 1 and forms spiral air curtain, has stopped dust to diffusion at a distance, is convenient to the dust suction of deduster.
