It is welded afterwards with air distributor, one end of discharge pipe is welded after furnace sidewall concrete-shell with collecting box；
When furnace bottom is in non-operating state, the other end of blast pipe and discharge pipe is equipped with sealing device；
When furnace bottom is in operating status, the sealing device on other end blast pipe and discharge pipe is removed, and wind will be connected
The air outlet of one end access discharge pipe in road.
The furnace bottom interlayer is the hollow passageway of laying fireproof bricks, is moved towards in serpentine, turning point is located at the one of quirk bottom
End.
The blast pipe and discharge pipe are metal riser, with boiler face with high.
The collecting box is in funnel-form, and material is heating resisting metal.
The connection air duct is inverted " u "-shaped structure, common metal material, and connection air duct one end and discharge pipe inserts when operation
Mouthful be connected, the go in ring smoke evacuation end socket of flue of the other end and stove is connected, when non-operating state the dismounting of connection air duct leave unused.
The sealing device is made of sealing cover, protection inner cover and seal receptacle, under non-operating state, sealing cover and seal receptacle
Between have refractory fibre and water seal two seals.
Due to using technical solution as described above, the utility model that there is following superiority：
A kind of open type cathode baking furnace furnace bottom described in the utility model, construction is simple, cooling effect is apparent, operation side
Just rapid, performance is stablized, and service life is high, and product quality and production capacity is made to be guaranteed, and electrical heat energy utilization rate is high, operation and
Maintenance cost is low.
