Summary of the invention
The present invention provides a kind of flue wall structure for anode baking furnaces in order to solve the problems of the technologies described above, purpose be solve that filling Jiao that the straight-through upright crack structure of existing anode roasting fire path wall laid dry brings enters easily that quirk, scaling loss are big, hopper inserts cover layer attenuate, cooling air easily suck hopper and cause the oxidation of anode product and difficulty of construction big, the wide seam defect of formation such as is difficult for remedying at problem.
Be achieved in that a kind of flue wall structure for anode baking furnaces for reaching above-mentioned purpose the present invention, comprise quirk body of wall, quirk wall special form brick, it is characterized in that being provided with between the adjacent quirk wall special form brick on the same horizontal plane the upright brickwork joint of broken line shape, the brickwork joint of neighbouring quirk wall special form brick is provided with high-temperature agglomerant.
Described quirk wall special form brick top and bottom are respectively equipped with rim of the mouth and female mouth.
The upright brickwork joint of described broken line shape has consistent incline direction on quirk wall plane, this direction is consistent with the airflow direction of flue gas in the quirk.
The upright brickwork joint of described broken line shape is made up of two end seams and a middle part seam.
The direction of described end seam is perpendicular to quirk wall surface.
The direction of described middle part seam then is the α angle with quirk wall surface, and the scope of α angle is 0.5～90 °.
Described high-temperature agglomerant is the high temperature clay.
The present invention has the following advantages:
1, the quirk special form brick that has adopted two ends to have broken line shape end face is built the quirk wall by laying bricks or stones, can form the upright seam of broken line shape laid dry as the fugitive constituent passage on each layer brick masonary.
2, the broken line shape fugitive constituent passage of being made up of the upright seam of numerous broken line shape laid dry can stop and fill the burnt quirk burning that sucked in a large number, effectively reduces and fills burnt scaling loss consumption.
3, can effectively keep the hopper top to fill the thickness of the bed of material, prevent that fresh air from entering hopper and the antianode goods produce oxidation, improve anode goods yield rate.
4, can reduce the anode goods oxidation that produces in the cooling procedure to enter the air generation retardation of hopper in the cooling furnace chamber by quirk.
5, in case take place because the overshoot of quirk wall special form brick error causes the upright brickwork joint width of laid dry to exceed standard, can do the trace swing to the quirk special form brick when building by laying bricks or stones, reach the purpose of limited adjustment, effectively solve the difficulty of building construction.
6, simple in structure, easy to implement.
