Description
Technical field
The utility model relates to ventilator field, particularly relates to a kind of ventilator for mine ventilation.
Background technique
At underground coal mine, due to the impact such as to rot of the breathing of the gushing out of gas, the flying upward of coal dust, personnel, mine timber, make to be harmful to, toxic gas constantly increases; Meanwhile, along with the increase of well depth, downhole temperature also will raise.Therefore, underground work personnel work for a long time in this environment, not only unhealthful, even also can suffocate.Particularly when the content of the biogas in air and coal dust exceedes specified value, likely cause gas that consequence is serious, coal-dust explosibility.In order to ensure that the health and safety of underground work personnel is produced, underworkings just must be made constantly to exchange with the fresh air on ground with the vitiated air in working surface, carry out centrifugal Mine Ventilator, improve working conditions.And traditional centrifugal mine ventilation machine equipment, its complex structure, ventilation effect is not good, and energy consumption is large.Coal Mine Ventilator has two kinds substantially, main air blower and booster.Main air blower is generally arranged on ground, mostly is draw-out type, and have downcast and meeting ventilating shaft, form full negative pressure ventilation system in down-hole, booster is mainly used in, in tunnelling, being arranged on down-hole, mostly is forced.Effect is mainly used for providing fresh distinguished and admirable, the dilution in down-hole and discharges down-hole harmful gas, cooling.The principle of ventilator distinguished and admirablely to be entered from wind collecting unit, obtains energy, then flow into stator by the impeller rotated, kinetic energy is transferred to rest energy by stator, distinguished and admirable by diffusion barrel, reduce flow velocity further, axial distinguished and admirable kinetic energy is converted into static energy, finally enters in air.
Model utility content
The utility model provides a kind of mine ventilator, is characterized in compact structure, sturdy and durable, use safety, easy to maintenance.
The utility model is achieved through the following technical solutions:
A kind of ventilator, comprise cylindrical shell, described cylindrical shell two ends are provided with slip ring, air draft cone mouth, described slip ring one end is provided with every stream chamber, described every stream inside, chamber be provided with the first motor, first motor is connected with the first impeller, and described air draft cone mouth place is provided with diffuser inside described in diffuser and is provided with the second motor, and described second motor is connected with the second impeller.
As optimal technical scheme of the present utility model, described cylindrical shell, slip ring, air draft cone mouth arranged outside have supporting leg.
As optimal technical scheme of the present utility model, described diffuser is the circular cone that diameter reduces gradually.
As optimal technical scheme of the present utility model, described first motor, the second motor are permanent magnet motor.
Compared with prior art, the beneficial effects of the utility model are: the position of the first impeller of the present utility model, the second impeller setting is close, first impeller, the second impeller respectively with the first motor, the second motor direct-connected, feature is compact structure, sturdy and durable, use safety, easy to maintenance.
