Background
Sintering machine system in large-scale ferrous metallurgy enterprise, through convulsions sintering, sinter into the bulk through adding water, the good mixture of balling with iron-containing material, flux, fuel etc. for the blast furnace uses. The sintering machine is used as main equipment of a sintering system, the stable operation rate of the sintering machine directly influences the operation efficiency of the sintering system, and the air leakage rate directly influences the production quality of sintered ores.
The air leakage part of the sintering machine is mainly provided with a head and tail sealing plate, a part between a trolley and a slideway, a part between the trolley and the trolley, and a part between a briquetting pin and a trolley body. In order to ensure that the grate bars do not fall off from the trolley, the pressing block pins are arranged on two sides of the trolley breast board, gaps are reserved between the pressing block pins and the breast board for convenient installation, although the gaps are not large, each trolley is provided with 6 pressing block pins, the total air leakage area is large, and the total air leakage rate is influenced.
The traditional grate briquetting pin has the following defects in the long-term use process:
1. gaps are reserved between the grate briquetting pins and the trolley breast boards, and air leakage is generated;
2. the grate briquetting pin is seriously burnt and the gap is gradually enlarged;
3. and the material is easy to fall off after serious burning loss.
Therefore, how to treat the air leakage of the grate briquetting pin becomes a problem to be solved urgently by related technical personnel.
Disclosure of Invention
The utility model aims at providing a device that improvement sintering machine grid section briquetting leaked out through the cooperation mode between adjustment platform truck breast board and the briquetting round pin, changes briquetting round pin layering position size and briquetting round pin fixed mode, reduces grid section briquetting round pin scaling loss, reduces to leak out between briquetting round pin and the platform truck breast board, improves sintering mineral products quality, has solved the above-mentioned problem that exists effectively among the background art.
The technical scheme of the utility model is that: a device for improving air leakage of a grate briquetting of a sintering machine comprises a breast board body, a wedge-shaped briquetting pin and a locking nut, wherein a pore is formed in the outer side of the breast board body, the pore is in a circular hole shape, and a square wedge shape with an included angle of 30 degrees is formed in the inner side of the breast board body; the wedge-shaped pressing block pin is matched with the hole of the breast board body, the outer side of the wedge-shaped pressing block pin is cylindrical, the inner side of the wedge-shaped pressing block pin is in a 30-degree wedge shape, and the pressing grate bar part is in a 100mm wedge shape; the end part of the wedge-shaped pressing block pin is fixed with the breast board body through a locking nut.
The end part of the wedge-shaped pressing block pin is a bolt-shaped end part, pressing block pin outer side threads are arranged on the bolt-shaped end part, and the pressing block pin outer side threads are matched with the locking nut.
The utility model has the advantages that: by adjusting the matching mode between the trolley breast board and the briquetting pin, the size of the position of the briquetting pin pressing strip and the fixing mode of the briquetting pin are changed, the burning loss of the grate briquetting pin is reduced, the air leakage between the briquetting pin and the trolley breast board is reduced, and the sintering mineral product quality is improved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic view of the enlarged partial structure of the present invention;
in the figure: the guardrail plate comprises a guardrail plate body 1, a wedge-shaped pressing block pin 2, a bolt-shaped end portion 3, pressing block pin outer side threads 4 and a locking nut 5.
Detailed Description
In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the following will combine the drawings in the embodiment to clearly and completely describe the technical solution in the embodiment of the present invention, and obviously, the embodiment described is a small part of the embodiment of the present invention, rather than the whole embodiment, based on the embodiment of the present invention, all other embodiments obtained by the ordinary skilled person in the art without creative work belong to the protection scope of the present invention.
A device for improving air leakage of a grate briquetting of a sintering machine comprises a breast board body 1, a wedge-shaped briquetting pin 2 and a locking nut 5, wherein a pore is formed in the outer side of the breast board body 1, the pore is in a circular hole shape, and a square wedge shape with an included angle of 30 degrees is formed in the inner side of the breast board body; the wedge-shaped pressing block pin 2 is matched with a pore of the breast board body 1, the outer side of the wedge-shaped pressing block pin 2 is cylindrical, the inner side of the wedge-shaped pressing block pin 2 is in a wedge shape of 30 degrees, and the bar part of the pressing grate is in a wedge shape of 100 mm; the end part of the wedge-shaped pressing block pin 2 is fixed with the breast board body 1 through a locking nut 5.
The end part of the wedge-shaped pressing block pin 2 is a bolt-shaped end part 3, a pressing block pin outer side thread 4 is arranged on the bolt-shaped end part 3, and the pressing block pin outer side thread 4 is matched with the locking nut 5.
In practical application, the utility model discloses a working process as follows:
the first step breast board body 1 is the main structural component of the grid section, and is adjusted into the shape of a circular hole on the outer side of the breast board body from the original shape of the circular hole, and the square wedge shape with an included angle of 30 degrees on the inner side.
