Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1 and 2, the smoke exhaust device of the vertical bauxite calcining kiln comprises a furnace door 1, a baffle plate 3, a smoke hood 2, a smoke exhaust pipeline 4, a steering wheel 5, a winding roller 9, a first regulating wheel 7, a second regulating wheel 8, a furnace body 10 and a pneumatic motor 11. The baffle plates 3 are positioned on two sides of the furnace door 1; is fixed on the upper part of the furnace body; the smoke hood 2 is arranged on the inner side of the baffle 3, and the smoke exhaust pipeline 4 is arranged above the furnace door 1.
