Abstract
The utility model discloses a pressure-release air door. A pressure-release hole is formed on a door leaf of the conventional air door; and a pressure-release fan is mounted on the pressure relief hole. The air door has the advantages that the pressure-release hole is firstly opened before the air door to ventilate part of air, and the air door can be easily opened after the pressure is released.
Description
Technical field
The utility model relates to the coalmine ventilation facility, relates in particular to air door.
Background technology
Along with the raising of coal winning technology and the continuous increase of Coal Production scale, to the also corresponding increase of the required air quantity in colliery, the result who brings is the local tunnel in colliery, and the connection roadway of particularly total air intake and total return air has wind speed height, air quantity is big, blast is big characteristics.If at the common air door of these local installations, because blast is big especially, air door is difficult to open, even two or three people is difficult to open.This has not only influenced production, but also can be with potential safety hazard, and traditional way is a design and installation power-assisted handle on air door, though obtained some effects, in the big place of blast, because the air door local pressure is excessive, air door still is not easy to open.
Summary of the invention
For addressing the above problem, the utility model has designed a kind of pressure release type air door.
A kind of pressure release type air door, it comprises existing air door, it is characterized in that, has pressure relief opening on the door leaf of original air door, and the pressure release fan is installed on the pressure relief opening.
Above-mentioned pressure relief opening has two kinds of forms: a kind of is the observation port formula, and pressure relief opening is located at door leaf top as window, is used to observe mine car operating condition in the tunnel of track is arranged simultaneously.Another kind is little gate-type, and pressure relief opening is located at position, door leaf middle and lower part as wicket, can open wicket, only is used for the pedestrian and passes through.In the tunnel that does not have locomotive to pass through, visual window is originally used pressure relief opening instead and is replaced.
The utility model has the advantages that: before opening air door, open pressure relief opening earlier and allow the part wind circulation, treat that pressure is laid down after, just be easy to open air door.
Description of drawings
Fig. 1 is the front view of observation port formula relief damper;
Fig. 2 is the front view of wicket formula relief damper.
Marginal data: 1-door leaf; 2-pressure release sash; 3-pressure release door leaf.
The specific embodiment
As shown in Figure 1, be provided with pressure relief opening, pressure release sash 2 is installed on the pressure relief opening on the top of door leaf 1.
As shown in Figure 2, door leaf 1 the position, middle and lower part be provided with pressure relief opening, pressure release door leaf 3 is installed on the pressure relief opening.
Claims (2)
1. pressure release type air door, it comprises air door, it is characterized in that, has pressure relief opening on the door leaf of air door, and the pressure release fan is installed on the pressure relief opening.
2. pressure release type air door as claimed in claim 1 is characterized in that described pressure relief opening is located at door leaf top as window.
3
.Pressure release type air door as claimed in claim 1 is characterized in that, described pressure relief opening is located at position, door leaf middle and lower part as wicket.
