Description
Technical field
The invention belongs to mining machinery technical field, more particularly to a kind of annular air door of slide-open.
Background technology
Due to special work condition environment, there are very strict requirements in shaft production to underground ventilating.Methane accumulation and
Gas exceeding limit is the major hidden danger of mine safety production, and this is accomplished by by being divulged information incessantly to mine ventilating shaft, to actuate well
The flowing of lower air, so as to dilute fire damp concentration, it is to avoid the exceeded phenomena impair mine of gas occurs for local high methane area
Safety in production.Air door is mostly important in a whole set of mine ventilation system, and it controls ventilation and direction of ventilation.Mine ventilating shaft is needed
Irregularly maintenance of fan carried out using air door and fall machine and failure machine, and the method for machine is generally fallen using blowing-out at present and carries out day
The normal work of falling machine, i.e., first stop main fan ventilation, then realize the replacing of ventilation air duct by adjusting air door, then restart main fan
Draft fan, this process of falling machine generally requires the time of 5-10 minutes, is off in the meantime to underground air feed.And in ore deposit
Many highly gassy mine blowing-outs just occur that local gas is exceeded for one minute in well actual production, particularly in normally ventilation situation
Under, wind speed formed by underworkings section size, right and wrong angle are different with on-way resistance is different, distinguished and admirable inertia meeting during blowing-out
Random wind phenomenon is caused, the long time of falling machine, most of mines can not be born, therefore, occur in that several can realize not
The new-type air door of machine is fallen in blowing-out, mainly has vertical lock gate hatch, venetian blind type vane air door and vertical insertion plate door at present, this three classes wind
Although door can realize the constant ventilation during machine, we have found that vertical lock gate hatch and vertical in actual application
The lifting process of formula insertion plate door is wasted time and energy, and venetian blind type vane air door because causing rotating shaft more blade more, one during use
One rotating shaft corrosion of denier is accomplished by carrying out air door integral replacing, and to ensure the sealing of whole ventilating duct during air door closing,
Be both needed to set a set of seal assembly on each blade of venetian blind type vane air door, assembling is complicated, and cost is higher, in addition, this three
Plant air door and also all there is the problem of air intake is uneven, the uneven real-time working condition measurement that may result in ventilation blower of air intake is inaccurate,
The safety in production of mine can be threatened.
As can be seen here, prior art awaits further improving.
