Abstract
The utility model discloses the large-capacity ore furnace structure of a kind of convenient smoke evacuation, including body of heater, three electrodes it are provided with in described body of heater, periphery at body of heater is along the circumferential direction evenly equipped with three fire doors, and it is provided with smokejack between each fire door, described smokejack includes the dado extended up bottom mineral hot furnace, the oblique flue tube being arranged on described dado and extending obliquely, and is arranged at the smoke guiding cover on described oblique flue tube top.In the large-capacity ore furnace structure of convenient smoke evacuation described in the utility model, make flue gas transmission path substantially shorten by changing the set-up mode of flue, can make flue gas that ferrosilicon smelting process produces more directly, quickly derive；Extend up simultaneously as the external boundary of flue i.e. dado is the bottom from mineral hot furnace, therefore can be obviously reduced the volume of mineral hot furnace, be conducive to saving construction cost, and the execute-in-place for workman provides convenient.
Description
Technical field
This utility model relates to a kind of mineral hot furnace structure, particularly relates to the large-capacity ore furnace structure of a kind of convenient smoke evacuation.
Background technology
Mineral hot furnace is also known as electric-arc furnace or resistance electric furnace.
It is mainly used in reducing and smelting Ore, the raw material such as carbonaceous reducing agent and solvent.Mainly produce ferrosilicon, ferromanganese, ferrochrome,
The ferroalloy such as ferrotungsten, silicomangan, is the industrial chemicals such as essential industry raw material and carbide in metallurgical industry.
Its work characteristics is to use carbonaceous or magnesia refractories to make furnace lining, uses from training electrode.Electrode inserts furnace charge and enters
Row arc-covering slag operation, utilizes the energy of electric arc and electric current to pass through furnace charge, produces energy because of the resistance of furnace charge and carry out smelting metal, successively
Charging, batch (-type) goes out scum, a kind of industrial furnace worked continuously.
Mineral hot furnace mainly by furnace shell, bell, furnace lining, short net, water-cooling system, smoke evacuation system, dust pelletizing system, Electrode Fluctuation and
Jacking system and various electric equipments etc. form.
In prior art, cylindrically, and its flue protrudes out cylinder edge and is separately provided mineral hot furnace, and this results in
The overall volume of mineral hot furnace becomes big, improves construction cost, and flue gas transmission exists smooth, workman's execute-in-place there is also many not
Just.
Utility model content
This utility model is for the drawback of prior art, it is provided that the large-capacity ore furnace structure of a kind of convenient smoke evacuation.
The large-capacity ore furnace structure of convenient smoke evacuation described in the utility model, including body of heater, is provided with three in described body of heater
Individual electrode, the periphery at body of heater is along the circumferential direction evenly equipped with three fire doors, and is provided with smokejack between each fire door, described row
Flue includes the dado extended up bottom mineral hot furnace, the oblique flue tube being arranged on described dado and extending obliquely,
With the smoke guiding cover being arranged at described oblique flue tube top.
In the large-capacity ore furnace structure of convenient smoke evacuation described in the utility model, described dado is built into by masonry, and height is
Between 0.8 meter to 1.2 meters.
In the large-capacity ore furnace structure of convenient smoke evacuation described in the utility model, described oblique flue tube includes outside metal
Shell, the inwall at described metal shell is attached with flame retardant coating.
In the large-capacity ore furnace structure of convenient smoke evacuation described in the utility model, make cigarette by changing the set-up mode of flue
Gas transmission path is substantially shortened, and can make flue gas that ferrosilicon smelting process produces more directly, quickly derive；Simultaneously as cigarette
The external boundary in road i.e. dado is that the bottom from mineral hot furnace extends up, and therefore can be obviously reduced the volume of mineral hot furnace, favorably
In saving construction cost, and the execute-in-place for workman provides convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of the large-capacity ore furnace of convenient smoke evacuation described in the utility model；
Fig. 2 is another structural representation of the large-capacity ore furnace of convenient smoke evacuation described in the utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail, to make those skilled in the art with reference to explanation
Book word can be implemented according to this.
As it is shown in figure 1, the large-capacity ore furnace structure of convenient smoke evacuation described in the utility model, including body of heater 1, described stove
Being provided with three electrodes 12 in body 1, the periphery at body of heater 1 is along the circumferential direction evenly equipped with three fire doors 13, and each fire door 13 it
Between be provided with smokejack 14.
As in figure 2 it is shown, described smokejack 14 specifically includes the dado 2 extended up from the bottom of mineral hot furnace 1, and arrange
The oblique flue tube 3 and extended obliquely on described dado 2, and it is arranged at the smoke guiding cover 4 on described oblique flue tube 3 top.
This kind arranges the mode of flue makes flue gas transmission path substantially shorten, the flue gas that ferrosilicon smelting process can be made to produce is more direct,
Quickly derive；Simultaneously as the external boundary of flue i.e. dado 2 is to extend up from the bottom of mineral hot furnace 1, therefore can be bright
The aobvious volume reducing mineral hot furnace, is conducive to saving construction cost, and the execute-in-place for workman provides convenient.
In the large-capacity ore furnace structure of convenient smoke evacuation described in the utility model, described dado 2 is to be built by masonry 21
Becoming, its height, between 0.8 meter to 1.2 meter, the most both can ensure that and efficiently discharged flue gas, and can reduce again construction investment, with
Time, the most convenient with follow-up flue gas processing device is connected, and has extremely strong versatility.
In this utility model, described oblique flue tube 3 specifically includes metal shell 32, at the inwall of described metal shell 32
Being attached with flame retardant coating 31, described flame retardant coating 31 can be laid by refractory materials such as refractory brick and form.
Although embodiment of the present utility model is disclosed as above, but it is not restricted in description and embodiment
Listed utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art,
It is easily achieved other amendment, therefore under the general concept limited without departing substantially from claim and equivalency range, this reality
It is not limited to specific details and shown here as the legend with description with novel.
