For achieving the above object, the technical solution of the utility model is as follows:
A kind of smoke evacuation exhaust duct, described pipe main body is that outer wall is that rectangle, inwall are circular or oval-shaped cavity channel, four jiaos of places of the tube wall of described pipeline are equipped with through hole longitudinally, the outside of each through hole is equipped with and strengthens muscle one, be provided with one deck and strengthen net one between described through hole and enhancing muscle one, the inwall edge, two ends of described pipe main body respectively is provided with a circle concave edge groove.
Preferably, the outer wall of described pipe main body is square or rectangular.
A kind of connection set of the exhaust duct of discharging fume, the connecting sleeve that comprises hollow shape, the two ends of described connecting sleeve all are connected with the interface that can embed in the described concave edge groove, described connecting sleeve is provided with the carrying limit, described connecting sleeve central axis is provided with cyclone guide plate core pipe, is connected with the guide plate blade on the described cyclone guide plate core pipe.
Preferably, be provided with the enhancing angle steel in the described carrying limit.
Preferably, be provided with enhancing muscle two and enhancing net two in the described connecting sleeve.
By technique scheme, the smoke evacuation exhaust duct outer wall that the utility model provides is that rectangle, inwall are circular or oval, can reduce resistance of air, is provided with through hole longitudinally at the Si Jiaochu of tube wall, can alleviate the weight of pipeline, can also save cost; Strengthen muscle and strengthen net by setting up in inside, expose the problem of net in can solving, can also gain in strength, alleviate four jiaos breakage.
The concave edge groove of the interface of connection set and pipe ends is supporting, and effectively waterproof does not misplace, and makes simple and convenient; Be provided with cyclone guide plate blade in the hole, utilize air-flow when rising, can rotate during by each layer cyclone guide plate blade, thereby reach better smoke evacuation exhaust effect.
