Abstract
The utility model relates to a mine application device, especially relates to an inflatable ventilation wall for tunnel air quantity control. The inflatable ventilation wall for tunnel air quantity control comprises an air bag which is arch-shaped. The periphery of the air bag is provided with hooks, and the middle part of the air bag is provided with a sealing door, and the air bag is provided with a charge valve. The inflatable ventilation wall is small in volume, light in weight, and convenient in carrying.
Description
Technical field
The utility model relates to a kind of mine application apparatus, relates in particular to a kind of air filling type tunnel air quantity adjusting brattice that tunneling face air feed is regulated usefulness that is used for.
Background technology
Mine ventilation is an important step of down-hole Mine Safety in Production, and is reasonable, stable
,Mine ventilation system is the basis that guarantees that mine safety is produced reliably, along with the increase of the pit mining degree of depth, the increase of mining rate, must make that the mine air channel increases, the ventilation circuit extends, flowing resistance strengthens, and mine air-required volume also increases considerably.Suspend stope or other work plane that uses through intercepting, can reduce mine air-required volume, effectively improve the efficient of giving wind system, keep stable air quantity.The method that adopts at present is to intercept through the wall of laying bricks, and dismantles brick wall when needing to use again, and this method efficient is low, cost is high, also causes unnecessary waste.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art; The utility model provide a kind of can be effectively obstruct or half through the tunnel intercept and reach air quantity and regulate; Reduce unnecessary air quantity and run off, and simple in structure, easy for installation, can use repeatedly and volume is little, light weight, air filling type tunnel air quantity easy to carry are regulated brattice.
The utility model solves the technical method that its technical problem adopted: a kind of air filling type tunnel air quantity is regulated air baffle wall, comprises air bag, and this air bag is arch door shape, around air bag, is provided with hook; Middle part at air bag is provided with hermatic door, and said air bag is provided with charge valve.
The beneficial effect of the utility model is: the mode of gas production capsule is used for the shutoff in tunnel, and the irregular surface in the hoistway can filled and be close to the air bag surrounded surface after the inflation pressurization, have good sealing property and applicability naturally.And assembling is easy, inflationtime is short, it is fast to prop up speed, can accomplish the installation or the recovery of product in general 15 minutes, has very high operating efficiency.Also water injection hole in the air bag in the past during use injects the water that the degree of depth is no more than 500mm, can strengthen the stability of air filling type brattice.In the middle of air bag, be provided with the hermatic door in passageway, the staff can free pass from the centre, does not influence the sealing of brattice.The utlity model has that volume is little, light weight, characteristics such as easy to carry, a people is a portability, is fit to the working environment in mine, down-hole.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-air bag, 2-hook, 3-hermatic door, 4-charge valve.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Referring to Fig. 1, a kind of air filling type tunnel air quantity is regulated air baffle wall, comprises air bag 1, and this air bag 1 is arch door shape, around air bag 1, is provided with hook 2; Be provided with hermatic door 3 at the middle part of air bag 1, said air bag 1 is provided with charge valve 4, in practical application; Be placed in the tunnel that needs shutoff through linking up with 2 air bags 1; Airduct is connected the charge valve 4 of air bag, airbag aeration is expanded automatically form a stifled brattice, after filling around the brattice and being close to the tunnel; Adjust suitable soft durometer according to field condition, shut charge valve then and accomplish inflation.Also water injection hole in the air bag 1 in the past during use injects the water that the degree of depth is no more than 500mm, can strengthen the stability of air filling type brattice.The utlity model has that volume is little, light weight, characteristics such as easy to carry, a people is a portability, is fit to the working environment in mine, down-hole.And assembling is simple, inflationtime is short, it is fast to prop up speed, can accomplish the installation or the recovery of product in general 15 minutes, has very high operating efficiency.The irregular surface in the hoistway can filled and be close to air filling type brattice surrounded surface after the inflation pressurization, have good sealing property and applicability.
