Axially extending bore in.
Due to the adoption of the above technical scheme, the utility model has following superiority:
1, by the way that flue bottom surface is set as arcuate structure, flue bottom stress concentration is avoided, the prior art is prevented
In flat flue stress deformation cause to contact with agitating paddle, destroy entire flue bottom, in turn result in the damage to whole equipment
It is bad;
2, protection pedestal is set in flue bottom, it, can be by protecting the drainage trough on pedestal will once leakage occurs in side
The leakage of possible appearance is discharged in the diversion trench in furnace body, and is discharged outside furnace body by spout hole, prevents leakage from flowing to bottom
Portion's corrosion and damage heater at the same prevent the equipment burning being likely to occur damage flue;
3, heater assembly can pass in and out flue by way of pulling and pushing, and facilitate the inspection, replacement, dimension of bottom heater
Shield.
