Abstract
The utility model discloses a special -shaped grid section of shaft furnace stoving bed, it includes that the angle is hung to comb board, bleeder vent, grid section and the grid section side is protruding, the utility model provides a special -shaped grid section of shaft furnace stoving bed, novel structure, according to dry bed and little water bar's structure, the shape of change grid section, it is firm to make grid section and little water bar combine, forms occlusal relationship between the upper and lower grid section, prevent because of the working of a furnace not up time the phenomenon of grid section takes place, the structure at both ends about the change grid section increases the grid section ventilation at both ends from top to bottom, enlarges effective draught area of stoving bed to effective reduce because of the working of a furnace not up time the probability of grid section takes place, effective draught area about 30% of expansion stoving bed reaches and improves the pellet quality, improves the purpose of pellet output.
Description
Technical field
This utility model is related to pellet production equipment field, specifically a kind of Shaft Furnace Drying Bed abnormity grid section.
Background technology
At present, known grid section front rectangularity.Surrounding is wrapped up by wallboard, in addition first air vent in upside almost by
Little water beam blocks, and causes ventilation effect poor, is unfavorable for the drying of green-ball.Extend the drying time of green-ball, directly restrict pelletizing
The yield of ore deposit；Grid section becomes 50 60 degree of angles to ride on the upside of little water beam, when blast wandering collapses the production accidents such as material, material spray.
Grid section easily drops.Grid section own wt is larger, increases the heavy burden of little water beam.Because grid section is stuffy on the upside of little water beam, easily
Cause temperature on the upside of little water beam more lower slightly than downside temperature；Make the upper and lower both sides of the little water beam expansion rate that expands with heat and contract with cold inconsistent, little water
Beam is yielding.
Utility model content
The purpose of this utility model is to provide a kind of Shaft Furnace Drying Bed abnormity grid section, to solve to carry in above-mentioned background technology
The problem going out.
For achieving the above object, this utility model provides following technical scheme：
A kind of Shaft Furnace Drying Bed abnormity grid section, it includes grate plate, air-vent, grid section hangs angle and grid section side is convex, described grate plate
Parallelogram shape, grate plate is evenly arranged with air-vent, and it is convex that described grate plate right-hand member side is provided with grid section side, described grate plate
It is provided with grid section below left end and hang angle；Multiple abnormity grid sections become 50 to sextants symmetrically to ride over formation shaft furnace on the upside of little water beam
Drying Bed supporting construction, hangs angle by grid section between upper and lower two special-shaped grid sections and coordinates lacing wire to form occluding relation, upper and lower two abnormity
Grid section, due to the parallelogram like of its end, forms space, and the special-shaped grid section of the top left and right sides is connected by ridge grid section.
As further program of the utility model：The end hypotenuse direction setting of the parallel grate plate of air-vent.
As this utility model further scheme：It is the cambered extension angle of inner band that described grid section hangs angle.
As this utility model further scheme：Described ridge grid section triangular shape, left and right side is provided with
Pore.
Compared with prior art, the beneficial effects of the utility model are：This utility model provides a kind of Shaft Furnace Drying Bed different
Shape grid section, structure is novel, according to the structure of Drying Bed and little water beam, changes the shape of grid section, makes grid section and little water beam combine jail
Gu, between upper and lower grid section, form occluding relation；The phenomenon of grid section is fallen when preventing because of blast wandering；Change grid section upper and lower ends
Structure, increase grid section upper and lower ends ventilation, expand Drying Bed available ventilation area, thus effectively reducing because of blast wandering
Shi Fasheng falls the probability of grid section；Expand the available ventilation area 30% about of Drying Bed, reach and improve pellet quality, improve ball
The purpose of nodulizing yield.
Brief description
Fig. 1 is the structural representation of Shaft Furnace Drying Bed abnormity grid section；
Fig. 2 is that Shaft Furnace Drying Bed abnormity grid section constitutes Shaft Furnace Drying Bed supporting construction schematic diagram；
In figure：1- grate plate, 2- air-vent, 3- grid section hang that angle, 4- grid section side be convex, 5- ridge grid section, 6- lacing wire, 7- little water beam.
Specific embodiment
With reference to specific embodiment, the technical scheme of this patent is described in more detail.
Refer to Fig. 1-2, a kind of Shaft Furnace Drying Bed abnormity grid section, it includes grate plate 1, air-vent 2, grid section extension angle 3 and combs
Bar side convex 4, described grate plate 1 parallelogram shape, grate plate 1 is evenly arranged with air-vent 2, the end of the parallel grate plate 1 of air-vent 2
Portion hypotenuse direction is arranged, and described grate plate 1 right-hand member side is provided with grid section side convex 4, is provided with grid section and hangs below described grate plate 1 left end
Angle 3, it is the cambered extension angle of inner band that described grid section hangs angle 3, and multiple abnormity grid sections become 50 60 degree of angles symmetrically to ride over little water beam 7
Upside forms Shaft Furnace Drying Bed supporting construction, coordinates lacing wire 6 to form occlusion by grid section extension angle 3 and close between upper and lower two special-shaped grid sections
System, upper and lower two special-shaped grid sections, due to the parallelogram like of its end, form space, are conducive to divulging information, the top left and right sides
Special-shaped grid section is connected by ridge grid section 5, described ridge grid section 5 triangular shape, and left and right side is provided with air-vent 2.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment party
Formula, in the ken that one skilled in the relevant art possesses, can also be on the premise of without departing from this patent objective
Make a variety of changes.
