Abstract
The invention discloses grid section of loop wheel machine of sintering machine that can improve work efficiency and prevent falling from the loop wheel machine of sintering machine. The grid section comprises grid section itself, air intake end above grid section, air outlet end below the grid section, both ends are mounting ends, and the air intake end of the said grid section is equipped with slant plane in favor of the gas flow move downwards from the both side of the grid section.
Description
Technical field
The present invention relates to sintering machine equipment, relate in particular to sintering machine bogie grates.
Background technology
Sintering pallet is one of vitals of sintering machine, and its quantity is a lot, work under bad environment.Chassis is filled mixing material (containing grate-layer material) back to the afterbody operation at head, and mixing material outer surface is burnt knot in the ignition furnace lower point, and under the effect of exhausting negative pressure, the mixing material is sintered and extends downwards, finishes and unload sintering feed in sintering machine afterbody sintering process.Chassis upset under tail star gear drives is returned along lower tracks again, and the charging of head feed place is returned in upset once more under the head star-wheel drives.The mixing stockpile is placed on bogie grates, and in sintering process, the sintering hot blast passes from being installed between a plurality of grid sections that are arranged side by side on the chassis beam, so the structure of bogie grates and arrange that the operating efficiency to sintering machine has bigger influence.The shortcoming of existing sintering machine bogie grates has: the one, and wind-guiding is poor, and exhausting efficient is low, causes the inefficiency of sintering machine; The 2nd, the ventilative property in grid section two ends is poor, and the sintering feed that is positioned at place, grid section two ends exists the wind-guiding dead band to influence sintering efficient; The 3rd, after the sintering pallet discharging, when lower tracks was returned, chassis upset and grid section also happened occasionally from the phenomenon that chassis falls down; The 4th, grid section and chassis beam contact area are big, and be also very big to the trolley body heat output, and the working environment of trolley body is caused harmful effect.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, provides a kind of and can improve the sintering machine operating efficiency, can prevent the sintering machine bogie grates that falls from sintering pallet.
Sintering machine bogie grates of the present invention, comprise the grid section body, the grid section upper part of body is an air intake, the bottom is an outlet air end, both ends are installation end, the air intake of described grid section body is provided with and is beneficial to the inclined plane that air-flow moves downward from grid section body both sides, and the installation end of described grid section body is provided with anti-fall muscle; Anti-fall muscle is the rib to grid section body both sides projection, and this rib one end extends to the grid section air intake, and the other end extends to the grid section outlet air end.
The installation end of described grid section body is provided with the side direction wind-guiding face that the air-flow that is beneficial to grid section body both ends moves downward, and the initiating terminal of side direction wind-guiding face is positioned at the end points below on inclined plane.
The installation end of described grid section body is provided with boss, and the boss bottom is the strip supporting surface, and the width of described strip supporting surface is less than the width of grid section body.
The below on described inclined plane is provided with the Attrition Reserve face adjacent with the inclined plane, and the Attrition Reserve face is a vertical plane.
Compared with prior art, advantage of the present invention just is: the air intake at the grid section body is provided with the inclined plane, makes flowing of air more smooth, and exhausting efficient is higher, thereby has improved the operating efficiency of sintering machine; Be provided with anti-fall muscle at installation end, when sintering pallet upset and when lower tracks is returned, anti-fall muscle can prevent effectively that grid section from falling down from chassis; Be provided with side direction wind-guiding face at installation end, the air at grid section two ends also can be fully mobile during from the chassis downdraft, avoids occurring the wind-guiding dead band, guarantees that the sintering feed near the grid section end also can be fully burned on the chassis; The width of the strip supporting surface of installation end makes the contact area of grid section and chassis beam littler less than the width of grid section body, reduces the heat output of grid section to the chassis beam, helps improving the working environment of trolley body; The below on inclined plane is provided with the Attrition Reserve face adjacent with the inclined plane, under the situation of inevitable sintering feed to the grid section wearing and tearing, makes the wear-resisting phase on inclined plane longer, improves grid section service life.

The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 and shown in Figure 7, sintering machine bogie grates of the present utility model comprises grid section body 1, the top of grid section body 1 is air intake, the bottom is an outlet air end, and both ends are installation end, and a plurality of grid section bodies 1 are installed on the chassis beam 8 side by side, the air intake of grid section body 1 is provided with and is beneficial to the inclined plane 2 that air-flow moves downward from grid section body 1 both sides, inclined plane 2 makes flowing of air more smooth, and exhausting efficient is higher, and air-flow direction is shown in arrow among Fig. 5.The installation end of grid section body 1 is provided with anti-fall muscle 4, and in the switching process of chassis backstroke, but the setting of anti-fall muscle 4 makes the grid section body 1 after the upset bigger with the contact area of chassis beam 8, can prevent effectively that grid section body 1 from deflecting, and falls down from chassis.The installation end of grid section body 1 is provided with side direction wind-guiding face 5, the initiating terminal 51 of side direction wind-guiding face 5 is positioned at the end points below on inclined plane 2, the clearing end 52 of side direction wind-guiding face 5 links to each other with anti-fall muscle 4, side direction wind-guiding face 5 is the low inclined-plane of the high clearing end of initiating terminal, the air at grid section two ends direction shown in arrow Fig. 1 flows during from the chassis downdraft, guarantees that the sintering feed near the grid section end also can be fully burned on the chassis.The installation end of grid section body 1 is provided with boss 6, and boss 6 bottoms are strip supporting surface 7, and the width L of strip supporting surface 7 is less than the width D of grid section body.Make grid section body 1 littler, reduce the heat output of 1 pair of chassis beam 8 of grid section body, help improving the working environment of trolley body with the contact area of chassis beam 8.The below on inclined plane 2 is provided with the Attrition Reserve face 3 adjacent with inclined plane 2, Attrition Reserve face 3 is a vertical plane, because sintering feed is difficult to avoid to grid section wearing and tearing when exhausting, Attrition Reserve face 3 is set in the case can makes the wear-resisting phase on inclined plane 2 longer, improve grid section service life.
