Description
Technical field
The utility model belongs to mining equipment technical field, is specifically related to a kind of coal mine ground main fan air door.
Background technology
Coal mine main fan has important function to Safety of Coal Mine Production, which is responsible to delivered downhole fresh air, discharges the critical function of dirty wind and dust, guarantee safety in production.Country's safety regulations in coal mine requires each mine main ventilator the using and the reserved.Conveniently two Fans run and switch, and all install dissimilar air door and do airtight switching and use between every Fans and wind cave.Present air door is all only installed a butterfly valve to do airtight switching, therefore, when its air door existed breaks down in running, must stop the technical problem that main fan just can be fixed a breakdown.
Summary of the invention
Do not shut down the technical problem that cannot fix a breakdown when the purpose of this utility model is breaking down in running of the existing air door existence of solution, a kind of coal mine ground main fan air door is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of coal mine ground main fan air door, comprise tunnel joint, butterfly valve and the first air duct, wherein: it also comprises laterally opened air door and the second air duct, one end of described tunnel joint is connected with the air intake of ventilating duct, the other end of tunnel joint is connected with the first air duct, butterfly valve is located between tunnel joint and the first air duct, the other end of the first air duct is connected with the air outlet of laterally opened air door, the air intake of laterally opened air door is connected with one end of the second air duct, and the other end of the second air duct is connected with the air outlet of blower fan.
Anti-explosion heating band is provided with on half section, a left side for the inner-outer door frame bottom of described laterally opened air door, base plate is provided with on half section, the right side of inner-outer door frame bottom, the upper face of base plate is provided with heating tube, below the lower face of base plate, be provided with the waste tank of band heater, the water inlet of waste tank is connected by pipeline with the delivery port of base plate.
Described butterfly valve is manual, electric dual-purpose butterfly valve.
The utility model adopts above technical scheme, a butterfly valve and a laterally opened air door are set between ventilating duct and blower fan, this laterally opened air door does standby air door and uses, laterally opened air door is in normally open, flow passage resistance force of waterproof does not increase, when butterfly valve break down need overhaul time, this laterally opened air door can be closed and overhaul.Solve existing air door exist break down in running time do not shut down the technical problem that cannot fix a breakdown.Therefore, compared with background technology, the utility model have not blowing-out state lower wind door break down easily get rid of and structure design simple, rotate flexibly and the advantage of good seal performance.
