Abstract
The utility model discloses a small-sized pneumatic local fan, which is characterized by adopting a pneumatic motor, with an anti-explosion housing and taking air pressure used for production in a mine as a power source, wherein fixed brackets are mounted in the anti-explosion housing; and the pneumatic motor, with fan blades mounted on the output shaft, is fixedly arranged on the fixed brackets. The small-sized pneumatic local fan provided by the utility model is used in a coal roadway, a half coal roadway, an excavation roadway and a drill site, in which an electrically-driven local fan can not be used for ventilation. In addition, the small-sized pneumatic local fan has the advantages that air can be stably provided for a long time; the small-sized pneumatic local fan is convenient to mount, debug, use and maintain; and gas accumulation can be effectively prevented.
Description
Technical field
The utility model relates to a kind of booster that is applied in the mine, especially is applied in the pneumatic booster in the occasion that can't use electronic booster in the mine in coal road, half coal road, digging laneway, the drill site.
Background technique
In the process of under coal mine, constructing, can produce a large amount of coal petrography dust and gas, the safety in production of serious threat mine and harm worker's is healthy.
The electronic local fans of high-power explosion-proofs in mine, have been adopted at present in a large number; But the terrian conditions such as other tunnels to some special producing place of mine such as drill site, non-getting working face are special; Conditions of manufacture, complicated geological condition; Can't use electric fan in the special tunnel, and the volume of Electric Explosion-proof fan is big, the transhipment difficulty, line arrangement is loaded down with trivial details.
The model utility content
The utility model is for avoiding above-mentioned existing in prior technology deficiency; Provide a kind of in light weight, be easy to carrying, move conveniently, not high to the air duct quality requirement, wind supply quantity big, save cost, the small-sized fast pneumatic booster of dismounting; Terrian conditions such as other tunnels to some special producing place of mine such as drill site, non-getting working face are special; Conditions of manufacture, complicated geological condition; Can't use the occasion of electronic local fan in the special tunnel,, guarantee construction safety to prevent gas exceeding limit.
The utility model technical solution problem adopts following technological scheme:
The structural feature of the small-sized pneumatic booster of the utility model is to adopt pneumatic motor; Said pneumatic motor is to press wind to be power source to produce in the mine to use; Explosion-resistant enclosure is set; Mounting and fixing bracket in said explosion-resistant enclosure, pneumatic motor are fixedly installed on the fixed support, on the output shaft of said pneumatic motor, fan blade are installed.
Compared with present technology, the utility model beneficial effect is embodied in:
1, the utility model volume is little, and is not high for the air duct quality requirement, is easy to carrying, moves, easy for installation.
2, the utility model adopts downhole production with pressing wind, takes conveniently, and wind supply quantity is stable.
3, the utility model is simple in structure, and convenient for maintaining is saved cost.

Label among the figure: 1 explosion-resistant enclosure; 2 fixed supports; 3 fan blades; 4 pneumatic motors; 5 pneumatic motor air intake pipes.
Embodiment
Referring to Fig. 3; Small-sized pneumatic booster in the present embodiment is to adopt pneumatic motor 4; Pneumatic motor 4 is to press wind to be power source to produce in the mine to use, and explosion-resistant enclosure 1 is set, and mounting and fixing bracket 2 in explosion-resistant enclosure 1; Pneumatic motor 4 is fixedly installed on the fixed support 2, and fan blade 3 is installed on the output shaft of pneumatic motor 4.
Referring to Fig. 1 a, Fig. 1 b, and Fig. 2 a and Fig. 2 b, in the practical implementation, explosion-resistant enclosure 1 can directly adopt at present the generally shell and the fan blade of the local fan of the anti-explosion electric of use with fan blade 3; Fixed support 2 is that three supporting legs are 120 degree distributions for two groups, every group of laterally arranging; Pneumatic motor 4 adopts mining BQF-IV type pneumatic sump pump pneumatic motor, produces in the mine to be connected with pneumatic motor air intake pipe 5 with air line, and fan blade 3 is arranged evenly by circumference by ten cast alumin(i)um leaves and constitute that fan blade 3 is installed in the axle head of pneumatic motor 4.
The utility model is taken to produce in the mine to use and is pressed wind to be the drive power source pneumatic motor, for the production scene provides stable wind regime.To produce during use with air line and be connected with the pneumatic motor air intake pipe, Open valve promptly drives small-sized pneumatic booster and devotes oneself to work.
