Abstract
The utility model provides a sintering machine grate strip and aims at solving the problem in the prior art. The sintering machine grate strip comprises a grate strip body which is provided with a limit block and a limit column nail. Hooks are arranged at the lower end of the grate strip body symmetrically. The length of the grate strip body is 490-493 mm, and the middle width of the grate strip body is 25 mm. The sintering machine grate strip has the advantage that the middle width of the grate strip body is reduced, a gap between adjacent grate strips in the same row is increased, venting area is increased, and ventilation rate and sintering efficiency of the surface of a trolley are improved. Vertical distances between the grate strips in adjacent rows, between adjacent grate strips in the same row and between the upper end of the grate strip and the hooks are increased. In a return stroke process, moving among the grate strips is flexible, loose materials fall freely in a free moving process of the grate strips, the materials are not adhered onto the grate strips or collected on the grate strips, and a sintering process is relatively stable. The vertical distances between the grate strips in adjacent rows, between adjacent grate strips in the same row and between the upper end of the grate strip and the hooks are increased so that the weight of the grate strip body is reduced, and the weight borne by the hooks is correspondingly reduced.
Description
Technical field
The utility model belongs to technical field of metallurgical equipment, particularly a kind of sintering machine grid section.
Background technology
Sintering machine grid section is mounted on the pallet, in order to supporting material, and utilizes the grate interspace to ventilate, and finishes the critical component of material sintering process.The basic structure of the grate strip that present domestic sintering pallet adopts comprises grate bar body substantially, limited block, banking pin, the hook of grate bar bottom, in normal production, the grate bar is complete to be arranged on the chassis, forms sintering exhausting working face, the limited block of its facade limits adjacent grate stripe pitch, guarantees that reasonable clearance is as draught area; During backhaul, the grate bar hangs on the chassis girder, prevents that the grate bar from coming off, and is movable by the backlash freedom of adjacent row's grate bar simultaneously, or by the rapping apparatus cleaning the gapped bulk cargo that is mingled with, guarantee free draught area; Though but present grate bar can satisfy basic production requirement, but Shortcomings: adjacent row's grate interspace, all too small with the vertical range between the adjacent grate interspace of row, grate bar grate bar upper end and the bottom hook, draught area is restricted, and mutual close-packed arrays, free limitation of activity, on the one hand ventilative rate is not high, and the grate bar can't be freely movable when backhaul on the other hand, grate bar sizing phenomenon is serious, forms the vicious circle that draught area is progressively dwindled.
The utility model content
The purpose of this utility model provides a kind of sintering machine grid section, to solve problems of the prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of sintering machine grid section comprises grate bar body, and described grate bar body is provided with limited block and spacing stud, and grate bar body lower end is arranged with hook, and the length of described grate bar body is 490～493mm, and the intermediate width of grate bar body is 25mm.
The thickness of described limited block is
2.75～3.25mm
Vertical range between grate bar body upper end and the hook
71～73mm
The beneficial effects of the utility model are:
Compare with former use grate bar structure, the effect of three aspects is arranged: 1. grate bar body intermediate width reduces greatly, increases with the adjacent grate interspace of row, and draught area increases, and has improved the ventilative rate of trolley surface, thereby has improved sintering efficient; 2. adjacent row's grate bar, the together vertical range increase between the adjacent grate bar of row, grate bar upper end and the hook, the grate bar is mutually flexible movements in the backhaul process, and bulk cargo is free dropping in the free active procedure of grate bar, and the grate bar is not stained with material, no backup, draught area is guaranteed, and sintering process is relatively stable; 3. adjacent row's grate bar, the together vertical range increase between the adjacent grate bar of row, grate bar upper end and the hook, the weight saving of grate bar body, the grate bar of equal rigidity is made in the corresponding reduction of weight that hook bears, and the weight of comparable former use grate bar has certain amplitude to reduce.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the left view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As Figure 1-3, the utility model sintering machine grid section comprises grate bar body 1, and grate bar body 1 is provided with limited block 2 and spacing stud 3, and grate bar body 1 lower end is arranged with hook 4, the length of grate bar body 1 is 490～493mm, the intermediate width 25mm of grate bar body 1.
Vertical range between grate bar body 1 upper end and the hook 4
71～73mm
The utility model is compared with former grate bar structure, and adjacent row's grate bar, the vertical range of arranging between adjacent grate bar, grate bar upper end and the hook together all increase, and draught area strengthens on the one hand, improved the ventilative rate of trolley surface, thereby improved sintering efficient, reduced energy consumption, increased output; The grate bar moves relatively flexibly in the backhaul process on the other hand, and bulk cargo is free dropping in the free active procedure of grate bar, and the grate bar is not stained with material, no backup, and draught area is guaranteed, thus the stable sintering process; Moreover, the weight saving of grate bar body, the grate bar of equal rigidity is made in the corresponding reduction of weight that hook bears, and the weight of comparable former use grate bar has certain amplitude to reduce.
