Abstract
The invention discloses a sintering machine trolley combined type integration nodular cast iron grate device. The sintering machine trolley combined type integration nodular cast iron grate device comprises a grate upper body and a grate lower body, wherein the grate upper body is combined with the grate lower body through a groove buckle to form a whole grate. A clamp table is arranged at the lower end of the grate upper body, a clamp groove is formed in the upper end of the grate lower body, and the grate upper body is fixed into the clamp groove of the grate lower body in a clamped mode through the clamp table. The clamp table is a forked-tail table or a T type table, and the clamp groove is correspondingly formed to be a forked-tail groove or a T type groove. By means of sintering machine trolley combined type integration nodular cast iron grate device, the manufacturing cost of grates with the same number can be reduced, the whole ventilation rate and the rigidity of the grate are improved, the service life of the grate is prolonged, meanwhile, the sintering machine trolley combined type integration nodular cast iron grate device can be quickly disassembled and assembled on a sintering trolley, a large amount of time is saved, and the labor intensity is reduced.
Description
Technical field
The present invention relates to bogie body of sintering machine, specifically a kind of sintering pallet combined type integrated spheroidal graphite cast-iron grid section device.
Background technology
In metallurgy industry, sintering deposit has important function as the upstream process of ironmaking, and whether the burning of sintering feed fully directly has influence on energy consumption during smelting, therefore must ensure the sufficient combustion of sintering feed; Now metallurgy industry popular imitation frosted glass method be that sintering feed is carried out cloth on sintering pallet, then flame combustion is carried out by sintering machine, utilize air blast to carry out cross-ventilation at sintering pallet bottom simultaneously, allow the upper pyrometer gas of sintering feed carry out convection current from chassis top through pallet bottom, thus drive the sintering feed Thorough combustion of chassis bottom.
Grid section is as the significant components on sintering pallet, can burn smoothly to sintering feed and play an important role, grid section is covered with on sintering pallet, plays carrying effect to sintering feed, leaves 5mm gap between two grid sections simultaneously, the effect of ventilation by forced draft mouth is played in this gap, ensure hot blast from top to down through sintering feed, in actual production process, for improving cross-ventilation effect, need to increase the overall gap between grid section while reducing leakage material, improve ventilative rate.Therefore need to take a kind of design newly, when not affecting pallet and running, improve the ventilative rate of grid section, improve the service life of grid section simultaneously, reduce the loss amount of sintering feed.
Through retrieval, do not find constructed open source literature in the art.
Summary of the invention
The object of the present invention is to provide a kind of sintering pallet combined type integrated spheroidal graphite cast-iron grid section device, identical number grid section cost of manufacture can be reduced, improve overall ventilation rate and the rigidity of grid section, extend the service life of grid section, simultaneously can on pallet fast assembling-disassembling, save the plenty of time, reduce labour intensity.
In order to reach above-mentioned purpose, present invention employs following technical scheme, a kind of sintering pallet combined type integrated spheroidal graphite cast-iron grid section device, comprises castor bar upper body and castor bar lower body, and it is overall that described castor bar upper body and castor bar lower body are combined into castor bar by groove button each other.
Lower end, described castor bar upper body arranges chuck, and draw-in groove is offered in castor bar lower body upper end, and castor bar upper body is fixed in the draw-in groove of castor bar lower body by chuck.
Described chuck is forked tail platform or T stage, and what described draw-in groove was corresponding offers as dovetail groove or T-slot.
Compared to prior art, the present invention has following beneficial effect:
The mould of multiple single grid section is improved by combination, be designed to a kind of combined type integrated cast iron grid section mould, in this design, grid section is designed to upper body and lower body two entirety, castor bar upper body entirety is connected with thicker grid section two ends by dovetail groove, form a whole, its installation dimension is consistent with former single grid section, lower body only retains the hook contacted with chassis at two ends, the hook of mid portion grid section is cancelled, and under the prerequisite improving the overall ventilative rate of grid section, reduces the cost of spare part casting, reduce spare part weight, reduce labour intensity.

Detailed description of the invention
Detailed description for the present invention and technology contents, coordinate accompanying drawing to be described as follows, but accompanying drawing only provides with reference to the use with explanation, is not used for being limited the present invention.
According to Fig. 1-4, a kind of sintering pallet combined type integrated spheroidal graphite cast-iron grid section device, comprises castor bar upper body 1 and castor bar lower body 2, and it is overall that described castor bar upper body and castor bar lower body are combined into castor bar by groove button 3 each other.Lower end, described castor bar upper body arranges chuck, and draw-in groove is offered in castor bar lower body upper end, and castor bar upper body is fixed in the draw-in groove of castor bar lower body by chuck.Described chuck is forked tail platform or T stage etc., and what described draw-in groove was corresponding offers as dovetail groove or T-slot etc.
In grid section cast sections, the mould of multiple single grid section is improved by combination, be designed to a kind of combined type integrated cast iron grid section mould, in this design, grid section is designed to upper body and lower body two entirety, upper body entirety is connected with thicker grid section two ends by dovetail groove, form a whole, its installation dimension is consistent with former single grid section, lower body only retains the hook contacted with chassis at two ends, the hook of chassis mid portion grid section is cancelled, as shown in Figure 3, under the prerequisite improving the overall ventilative rate of grid section, reduce the cost of spare part casting, reduce spare part weight, reduce labour intensity.
Step one, casts thin integrated grid section upper body 1 and grid section lower body 2 respectively
Step 2, is connected by groove button 3, and namely grid section upper body 1 snaps in the dovetail groove offered castor bar lower body 2 upper end by the chuck that self lower end is arranged, and forms groove button and connects, and both are installed together and form combined type castor bar.
Step 3, combined type grid section is arranged on sintering pallet
This kind of design is that multiple single grid section is combined into a combined type grid section is integrated, this design is not simply connected by single grid section, but design on the whole, under the prerequisite improving the ventilative effect of identical number grid section, improve the stability of grid section on pallet, stop because chassis both sides grid section fixture block drops, and cause the problem that grid section drops from chassis, reduce the loss of the sintering feed therefore caused.
The foregoing is only preferred embodiment of the present invention, be not used to limit the scope of the claims of the present invention, other use the equivalence of patent spirit of the present invention to change, and all should all belong to the scope of the claims of the present invention.
