Abstract
The utility model relates to a sealing device for head and tail segments of a hot wind cover of a sintering machine. The sealing device is characterized by comprising a seal angle steel connected by a bolt assembly and a rack of hot wind cover of the sintering machine, a seal baffle plate arranged on the lower part of the seal angle steel, a hinged support connecting the seal angle steel and the seal baffle plate and a wear-resisting block arranged on the lower part of the seal baffle plate. The hinged support is formed by an upper connecting plate and a lower connecting plate rotationally connected with the upper connecting plate via a pin roll; the upper part of the pin roll is provided with a fixed pin; the lower part of the pin roll is provided with a spacing block; the seal angle steel is welded with the upper connecting plate; the seal baffle plate is welded with the lower connecting plate; and the seal baffle plate is rotationally connected with the seal angle steel via the pin roll on the hinged support. The sealing device for head and tail segments of hot wind cover of sintering machine is advantageous in that with the above sealing device, a sealed cavity is formed between the hot wind cover and a trolley, so air leakage rate is greatly reduced and sintering production capacity is increased.
Description
Technical field
The utility model belongs to metallurgy industry raw material sintering machine field, relates in particular to a kind of sintering machine air bells cap section sealing device end to end.
Background technology
Hot gas sintering technology is mainly to utilize the high-temp waste gas of central cooler, and the heat-agglomerating bed of material carries out sintering.In normal thick bed of material sintering process, auto accumulation heat effect is stronger, and material layer lower part heat is superfluous, top heat inadequate natural endowment.And hot gas sintering passes through to introduce the hot waste gas on cooler top, hot waste gas is transported in the air bells cap above chassis by pipeline, makes to raise by the gas flow temperature of the bed of material, the sintering temperature of the top bed of material is raise, and then reduce the temperature difference of upper and lower layer.Meanwhile, all right solid-fuelled combustion heat of Substitute For Partial, reduces solid fuel consumption, makes solid fuel more even in the distribution of sinter bed upper and lower part.Therefore air bells cap end to end the sealing of section the quality of sintering deposit is played to very important effect with saving production cost.
Existing sintering machine air bells cap sealing device is near sintering pallet place, to fix a block plate at air bells cap, fixing mode is that bolt connects or welding, along chassis traffic direction, on steel plate, be bolted heat resistance fiber plate again, make fiberboard as far as possible near trolley breast plate edge, with this, reach sealing effectiveness.In order to prevent damaged fiber plate in chassis running, must guarantee that fiberboard and trolley breast plate leave certain interval, so this kind stays apertured sealing means, its sealing effectiveness is not fine, the air leak rate of air curtain of sintering machine air bells cap is relatively large, thereby increases main exhauster energy consumption, reduces energy utilization rate, fiberboard is also easily damaged by operating chassis simultaneously, and maintenance workload is large.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and the sintering machine air bells cap that provide a kind of easy access, long service life, can reduce air leak rate of air curtain is section sealing device end to end.
The purpose of this utility model realizes by following technical proposals:
Sintering machine air bells cap of the present utility model is section sealing device end to end, it is characterized in that by the sealing angle steel being connected with sintering machine air bells cap support by bolt assembly, be arranged on the sealing baffle of this sealing angle steel bottom, the hinged-support that connects described sealing angle steel and sealing baffle forms with the wear-resistant block that is arranged on sealing baffle bottom, described hinged-support is comprised of the upper junction plate being rotationally connected by bearing pin and lower connecting plate, on described bearing pin top, be provided with steady pin, in described bearing pin bottom, be provided with positive stop, described sealing angle steel and upper junction plate welding, described sealing baffle and lower connecting plate welding, described sealing baffle is rotationally connected by the bearing pin on hinged-support and sealing angle steel.
Compared with prior art, advantage of the present utility model is just: owing to having adopted above-mentioned sealing device, the top layer sliding-contact of the sintered material on sealing catch and chassis, between air bells cap and chassis, formed annular seal space, can reduce greatly air leak rate of air curtain, improve sintering deposit production capacity, in addition because sealing device and air bells cap support are for being rotationally connected, by the material on chassis, promoting baffle plate rotates a certain angle, under baffle plate, along taking all the time, contact with sintering deposit upper surface slide, thereby sealing that can maintaining heat fan housing, and there is durability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, sintering machine air bells cap of the present utility model is section sealing device end to end, it is characterized in that by the sealing angle steel 3 being connected with sintering machine air bells cap support 1 by bolt assembly 2, be arranged on the sealing baffle 9 of these sealing angle steel 3 bottoms, the hinged-support that connects described sealing angle steel 3 and sealing baffle 9 forms with the wear-resistant block 10 that is arranged on sealing baffle 9 bottoms, described hinged-support is comprised of the upper junction plate 4 being rotationally connected by bearing pin 6 and lower connecting plate 8, on described bearing pin 6 tops, be provided with steady pin 5, in described bearing pin 6 bottoms, be provided with positive stop 7, described sealing angle steel 3 and upper junction plate 4 welding, described sealing baffle 9 and lower connecting plate 8 welding, described sealing baffle 9 is rotationally connected by the bearing pin 6 on hinged-support and sealing angle steel 3.
The utility model air bells cap end to end section be respectively provided with a sealing device, described sealing baffle 9 is subject to can rotate with respect to hinged-support under External Force Acting, the steady pin 5 on bearing pin 6 is used for limiting the position of sealing baffle 9 and hinged-support, prevents horizontal looseness.When material promotes after sealing device sealing baffle 9, sealing baffle 9 turns an angle, and 9 times wear-resistant blocks 10 of sealing baffle ride on sintering deposit, now between air bells cap and chassis, form the annular seal space of a sealing, air leak rate of air curtain greatly reduces, and is conducive to improve the intensity of sintering deposit, cost-saving.
The utility model is simple in structure, and processing installation accuracy requires low, has reduced gas consumption, is conducive to reduce production costs, and increases production and improves productivity.
