Description
Technical field
The utility model relates to technical field of ferrous metallurgy, more specifically to a kind of totally-enclosed board-like furnace of active face
Preceding air draught cover structure.
Background technique
With the continuous requirement of converter producing efforts at environmental protection, flue dust of the converter producing in fire door side must be collected place
Reason, wherein the main collecting device at fire door is stokehold suspended hood.Suspended hood mainly uses before smelter Converter at present
Two kinds of structure types, one is water-cooleds, and one is welded types.A generally existing problem is service life and using effect
It can not be adapted with converter.Under heat radiation effect of the water-cooled stokehold suspended hood by hot metal charging and blowing flame, water cooling tube
There is cracking water leakage fault and takes place frequently in road, and drastically influences the production at scene.Although the stokehold suspended hood of welded type avoids leak
Failure, but it is not perfect to make steel the stokehold welded type air draught cover structure design used at present, especially stokehold side, because it is contemplated that converting
The space of material, often air draught skin plate uses open by design, in practical smelt production, shows there are flue dust is excessive
As the metal chaining of the bead curtain type of some settings is basic without acting on and will burn quickly.
Utility model content
1. utility model technical problems to be solved
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of board-like stokehold of totally-enclosed active face
Air draught cover structure, the device effectively promote the service life of stokehold suspended hood, improve suspended hood dust removing effects.
2. technical solution
In order to achieve the above objectives, technical solution provided by the utility model are as follows:
A kind of totally-enclosed board-like stokehold air draught cover structure of active face of the utility model, including air draught cover body, it is described
It is provided with drop front at the center of air draught cover body, hinge, drop front are provided between air draught cover body and drop front
It is assembled by hinge and the activity of air draught cover body.
Further, the hinge is arranged at the side interval of air draught cover body.
Further, one end of the hinge is fixedly connected with air draught cover body, the other end and drop front of hinge
It is flexibly connected.
Further, the air draught cover body is made up of welding, and surfaces externally and internally is coated with refractory material.
3. beneficial effect
Using technical solution provided by the utility model, compared with prior art, have the following beneficial effects:
The utility model by setting can swing drop front, drop front can be according to ladle and steel scrap bucket
Corresponding swing occurs for physical location, can complete the totally enclosed demand of suspended hood body construction, nor affect on hot metal charging, stokehold
Side is totally-enclosed, and fire door side is open institution, increases the dust removal ability of air draught cover body, the flue dust for the spilling that blows can be rapidly by two
Secondary dedusting siphons away, and mitigates the Persistent Effect to sealing plate and air draught cover body, and air draught cover body is made up of welding, interior appearance
Face is coated with refractory material, to improve the service life of single unit system, improves dust removing effects.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1, air draught cover body；2, hinge；3, drop front.
Specific embodiment
The utility model will be further described with reference to the accompanying drawings and examples:
Embodiment 1
It will be seen from figure 1 that a kind of totally-enclosed board-like stokehold air draught cover structure of active face of the present embodiment, including suspended hood
Ontology 1 is provided with drop front 3 at the center of air draught cover body 1, is provided with hinge between air draught cover body 1 and drop front 3
2, hinge 2 is arranged at the side interval of air draught cover body 1, and one end of hinge 2 is fixedly connected with air draught cover body 1, hinge 2 it is another
One end is flexibly connected with drop front 3, and drop front 3 is assembled by hinge 2 and the activity of air draught cover body 1, drop front 3 can before
After swing, when inclining hot metal charging and steel scrap, drop front 3 can according to ladle it is corresponding with the generation of the physical location of steel scrap bucket pendulum
It is dynamic, it avoids influencing to incline to convert raw material, after the completion of inclining and converting, the flue dust generated in normal productive process is inhaled inside air draught cover body 1
Enter system, flue dust effectively can be limited in 1 inner cavity of air draught cover body by drop front 3, avoid excessive, can complete suspended hood sheet
The totally enclosed demand of 1 structure of body nor affects on hot metal charging, and stokehold side is totally-enclosed, and fire door side is open institution, increases suspended hood
The flue dust of the dust removal ability of ontology 1, the spilling that blows can be siphoned away by final dusting rapidly, be mitigated to sealing plate and air draught cover body 1
Persistent Effect, air draught cover body 1 by welding is made, surfaces externally and internally is coated with refractory material, to improve whole dress
The service life set improves dust removing effects.
Schematically the utility model and embodiments thereof are described above, description is not limiting, attached drawing
Shown in be also one of the embodiments of the present invention, actual structure is not limited to this.So if this field
Those of ordinary skill enlightened by it, without deviating from the purpose of the present invention, not inventively design
Frame mode similar with the technical solution and embodiment, all should belong to the protection range of the utility model.
