The utility model provides a waste heat collection device for ultra -temperature shaft kiln discharge end, the device has installed the casing that plays surplus heat collecting effect additional in the shaft kiln lower extreme discharge gate department of conventionality, makes material after the shaft kiln is fired flow through earlier on the casing falls the conveyer again, and this casing plays surplus heat collecting effect as surplus heat collecting room. On this basis, set up surplus hot air duct on the casing end cover, utilized the fan induced air that makes progress, made the outside air flow into the casing via the clearance between casing and the conveyer, then upwards carried to the outside via surplus hot air duct, helped alleviating the obstructed problem of material dust. In addition, the wrap -around insulating layer of casing periphery can play the heat preservation effect, promote waste heat recovery rate, improves the drying efficiency, the utility model discloses technological improvement with the novelty has realized good technological effect, promotes broad prospect.
