An exhaust fan is disposed in the exhaust line and inside the box. A filter net is also disposed inside the box. A cooling spray port is arranged inside the exhaust fan. A plurality of cold storage packs are disposed inside the box between the intake line and the filter net. The low-temperature exhaust device according to the manner above enables effective exhaustion and is high in safety coefficient, simple in structure and safe and reliable.
Description
Technical field
The present invention relates to mining equipment field, particularly relate to a kind of coal mining low-temperature extractor fan.
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 a kind of coal mining low-temperature extractor fan, 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 coal mining low-temperature 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 induced draft fan inside is provided with cooling spray mouth, described box house is provided with multiple cold-storage bag, and described cold-storage bag is between air inlet pipeline and screen pack.
In a preferred embodiment of the present invention, described cold-storage bag uniform intervals is distributed on the inwall of casing, and described cold-storage bag is ice bag.
In a preferred embodiment of the present invention, described bottom half is provided with collecting tank, and described collecting tank is connected with the lower end of induced draft fan by fluid pipeline.
In a preferred embodiment of the present invention, the bottom of described collecting tank is provided with leakage fluid dram, and described fluid pipeline is connecting hose.
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, and described casing is hermetic type rectangular box.
The invention has the beneficial effects as follows: coal mining low-temperature extractor fan of the present invention, can effectively air draft, safety factor is high, and structure is simple, safe and reliable.
