Technical field
The present invention relates to air duct technical field, more particularly to a kind of fire smoke extraction duct.
Background technology
Often to use the exhaust tube in ventilation air draft air duct, colliery within coal mines includes cylinder, and cylinder includes skeleton
Layer and be affixed on casing play surfaces externally and internally inner and outer surfaces layer, its cylinder for straight barrel type, i.e. cylinder two ends port diameter with
The diameter of cylinder is identical.It is not dedicated as the air duct of fire control smoke exhausting now, and air duct of the prior art its fire resistance property
It is poor, it is difficult to undertake smoke evacuation work after there is the condition of a fire.
The content of the invention
The invention aims to solve that there is unsuitable fire control smoke exhausting in the prior art, and the one kind proposed
Fire smoke extraction duct.
To achieve these goals, present invention employs following technical scheme：
A kind of fire smoke extraction duct, including cylinder are designed, the cylinder includes the basal layer of circular tube shaped, the appearance of the basal layer
Face is provided with fireprotection layer, and the inside of the basal layer is provided with the enhancement layer of circular tube shaped, sky is left between the basal layer and enhancement layer
Gap, is connected with multiple pull bars between the basal layer and enhancement layer, the inner surface of the enhancement layer is glued with refractory layer, the cylinder
The two ends of body are equipped with terminal pad, and the terminal pad is connected with basal layer, and the middle part of the terminal pad is provided with circular hole, the reinforcement
The end of layer is inserted into circular hole, and space is left between the terminal pad and enhancement layer.
It is preferred that, the outside of the fireprotection layer is equidistantly provided with the flap seat of multiple ring-types, and the top of the flap seat is provided with two
Suspension ring, the flap seat is made up of aluminium alloy, and the suspension ring are stainless steel ring.
It is preferred that, the edge of the terminal pad is evenly equipped with connecting hole along its circumference, and the terminal pad is made up of aluminium alloy.
It is preferred that, the refractory layer is silicon carbide layer, and the fireprotection layer is boron nitride layer.
It is preferred that, the enhancement layer is iron wire stratum reticulare.
A kind of fire smoke extraction duct proposed by the present invention, beneficial effect is：The present invention sets fire prevention respectively inside and outside
The structure of layer and refractory layer, can undertake and also leave space between the smoke evacuation work during condition of a fire, ectonexine, can play stop heat
Measure the effect propagated, additionally it is possible to obstruct the noise produced during work, inside set basal layer and enhancement layer, add the overall knot of air duct
Structure intensity, improves the service life of air duct.
Brief description of the drawings
Fig. 1 is a kind of structural representation of fire smoke extraction duct proposed by the present invention.
