Fire channel separating apparatus of anode baking stove

Abstract

The invention discloses an anode roasting furnace belonging to the production field of carbon used for aluminum, in particular to a flame path partition device of an anode roasting furnace. The structure of the flame path partition device of the anode roasting furnace is as flows: a plurality of furnace face function holes are arranged on the channels of the intersection of cross walls and flame paths among a plurality of furnace chambers and between the two rows of location pulling bricks; isolation positions are arranged on the channels among the furnace chambers underneath the furnace face function holes; a plurality of pressure bladders are arranged in the isolation positions; and the pressure bladders are communicated with a plurality of charging connectors arranged in the function holes. The invention has the advantages of simple structure, less weight, easy operation when being installed and discharged, low operation cost, high product quality, energy saving and good sealability even if the isolation positions are distorted at the high temperature.

Description

technical field [0001] The invention relates to an anode roasting furnace in the field of aluminum carbon production, in particular to an anode roasting furnace fire channel partition device. Background technique [0002] Anode roasting furnace will produce a large amount of flue gas during the production process of anode roasting. In order to discharge these flue gases, the anode roaster needs to be equipped with an annular flue outside the furnace body, and a smoke exhaust fan is installed at the general outlet of the annular flue to provide the required negative pressure for the exhaust of the flue gas. On the exhaust hole of the last low-temperature furnace chamber of the flame system running in the anode roaster, a special smoke exhaust device is provided to connect the furnace fire channel with the ring-shaped general flue channel, and at the same time, the flue gate is used to keep the smoke that does not enter the flame system The fire passages in the furnace room t...
