Description
Technical field
The present invention relates to coal mine machinery field, particularly relate to the explosion-proof extractor fan of a kind of underground mine use.
Background technology
During the driving coal work of colliery, work plane is blind alley, owing to constantly having Gas when driving is mined, now adopt bottom access lane, bobbin road of keeping watch and will blow out containing gas air with blasting method, to ensure worker safety, this method is net air due to what be blown into, fan blade and coal dust do not contact and do not rub, meet production safety code, but this method has broken up return air channel coal dust, make work plane air severe contamination, increase with the probability causing workman to suffer from anthraco-silicosis, as adopted existing induced draft fan exhausting, dirty wind will be discharged from air duct pipeline, work plane becomes clean wind passage, but fan blade will not meet production safety code with coal dust friction.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the explosion-proof extractor fan of a kind of underground mine use, can effectively air draft, and safety factor is high, and structure is simple, safe and reliable.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of underground mine use explosion-proof extractor fan, comprise: casing, one end of described casing is provided with air inlet pipeline, the other end is provided with air outlet pipeline, induced draft fan is provided with in described air outlet pipeline, box house is located at by described induced draft fan, also screen pack is provided with in the middle part of described casing, described casing top is provided with multiple cooled nozzle, described cooled nozzle is located between induced draft fan and screen pack, multiple water jet is also provided with in described casing, described water jet is arranged between air inlet pipeline and screen pack.
In a preferred embodiment of the present invention, the quantity of described cooled nozzle is 6, and described cooled nozzle is symmetricly set on the two ends up and down of casing.
In a preferred embodiment of the present invention, the quantity of described water jet is 2, and described water jet is symmetricly set on the two ends up and down of casing and setting skewed with screen pack.
In a preferred embodiment of the present invention, described screen pack comprises coarse strainer and fie screen, and described coarse strainer is arranged on the outside of fie screen.
In a preferred embodiment of the present invention, described casing is hermetic type rectangular box.
The invention has the beneficial effects as follows: the explosion-proof extractor fan of underground mine use of the present invention, can effectively air draft, safety factor is high, and structure is simple, safe and reliable.
