Abstract
The invention discloses an anode roasting furnace for aluminum in the field of non-ferrous metallurgical field, in particular to a wall body structure of the anode roasting furnace for aluminum, which is used to replace a thick wall body which is formed by a concrete casing and thick masonries. The invention reduces the heat storage loss of the furnace, and effectively reduces the width of the furnace, and has the advantages of saving heat energy, saving refractory and insulating material and plant area, enlarging furnace productivity, increasing furnace yield and quality and practicability.
Description
Technical field
The present invention relates to anode roasting furnace for aluminum, the wall body structure that particularly relates to a kind of anode roasting furnace for aluminum, basis and thickness of wall body in order to the attenuate anode roasting furnace for aluminum, alleviate the wall weight of anode roasting furnace for aluminum, improve the heat insulation effect of anode-baking furnace, reduce the accumulation of heat loss and the radiation loss of anode-baking furnace, the purpose that reaches energy savings, saves anode roasting furnace for aluminum floor space and minimizing refractory consumption rate.
Background technology
Body of wall around the anode roasting furnace for aluminum is this kind type of furnace primary structure, also is the main region of heat radiation of this kind type of furnace and accumulation of heat loss, its institute's material of using and masonry construction, not only influence the thermal efficiency of stove, and directly influence the body of heater width, and then influence the span of factory building.
Body of wall around the existing anode roasting furnace for aluminum is the insulation material that adopts various unlike materials, builds by laying bricks or stones to form in the shell of concrete basis.The body of wall of this structure has the shortcoming of following several respects: 1, in order to protect concrete basis shell internal surface temperature not exceed code requirement, must adopt thicker wall body structure, be passed to temperature on the shell of concrete basis in order to reduce quirk, cause that body of wall is thick, weight is big; 2, owing to employing concrete basis shell supports all around as stove, and the thickness of basic shell has caused the overall width of stove to increase considerably generally at 500mm, and then has increased the span of factory building, has improved the factory building cost, and the while has also been improved the cost of technology overhead traveling crane; 3, because thick and heavy body of wall and concrete foundation structure causes the heat loss of stove bigger.The stove of this periodical operation particularly, its accumulation of heat loss senior general is fatal shortcoming, serious retardation the speed of stove intensification, cooling, reduced the thermal sensitivity of stove, realization for the roasting technique curve has brought adverse effect, and then has reduced the production capacity of product quality and stove; 4, the smoke evacuation system of stove adopts annular flue, has taken a large amount of width spaces of factory building, as smoke evacuation in the middle of will changing into, the caused ad hoc installing space of concrete basis shell structure again basic neutralisation the width spaces of being saved.
Summary of the invention
It is to solve existing anode roasting furnace for aluminum body of wall and the thick and heavy caused accumulation of heat loss of basic concrete structure is big, energy-saving effect is poor, body of heater occupies that the factory building width spaces is big, smokejack is arranged unreasonable, the refractory material wasting of resources, the unfavorable problem of stove processing performance that the present invention is exactly to provide in order to solve the problems of the technologies described above a kind of anode roasting furnace for aluminum wall body structure, purpose.
In order to solve the problems of the technologies described above, the present invention is achieved in that a kind of wall body structure of anode roasting furnace for aluminum, it comprises furnace shell, building wall structure, and wherein furnace shell is a metal structure, and the building wall structure that is provided with in the furnace shell all adopts lightweight flame-proof thermal insulation material to build by laying bricks or stones and forms.
Described shell adopts steel to make.
Described shell is provided with to flue and stays installing space and the supporting base of establishing.
Anode roasting furnace for aluminum wall body structure of the present invention has the following advantages:
1, adopt steel construction stove shell, will effectively reduce the thickness of stove shell, only this item can dwindle body of heater width 1m.Also alleviate simultaneously the huge workload of basic shell construction, and can increase substantially the stove residual value.
2, behind the employing lightweight wall body structure, body of wall is attenuate obviously, and only this item can dwindle 1.7 meters m of body of heater width.
3, above-mentioned 2 points can reduce the stove accumulation of heat and lose about 16%.
4, can realize the ring-like flue of stove is changed into the straight type flue of middle smoke evacuation, only this item can dwindle body of heater width 2.3m.
5, above-mentioned total is saved furnace widths 5m.Stove production capacity 25% can be improved if increase to hopper in this space; If consider to reduce the factory building span, then can save plant area 75m
2/ ten thousand tons of production capacities also can obviously reduce the overhead traveling crane cost simultaneously.
6, can improve the thermal sensitivity of anode roasting furnace for aluminum, for optimizing the anode baking process curve and then providing the space for improving anode product quality and output.
Description of drawings
Attached 1 is the wall body structure schematic diagram of anode roasting furnace for aluminum of the present invention.
Among the figure, 1, furnace shell; 2, building wall structure; 3, supporting base.
The specific embodiment
Below embodiments of the invention are described in detail in conjunction with the accompanying drawings, but protection scope of the present invention is not limit by embodiment.
As shown in Figure 1, the wall body structure of anode roasting furnace for aluminum of the present invention is as follows: furnace shell 1 is a steel construction, and the building wall structure 2 that is provided with in the furnace shell 1 all adopts lightweight flame-proof thermal insulation material to build by laying bricks or stones and forms.On shell 1, be provided with to flue and stay installing space and the supporting base of establishing 3.
