Abstract
The utility model relates to a sleeve relief filter, belonging to a fluidization coal injecting tank supporting device in the blast-furnace coal powder injection technique. The sleeve relief filter comprises a filer drum, a filter screen end plate 4 and an inner filter drum, wherein the filter drum consists of a mounting flange 1, a connecting drum 2 and a filter screen 3; the inner filter drum consists of an inner connecting drum 5 and an inner filter screen 6; the mounting flange 1 is provided with air inlets 11 between the filter drum and the inner filter drum; and the filter screen end plate is provided with air vents 41. When in working, coal powder and gas mixture in a coal injecting tank enter the cavity between the inner filter drum and the outer filter drum by passing through theair inlets 11, one part of the gas can be relieved by the outer filter screen 3, the other part of gas can be relieved by the inner filter screen 6 by passing through the air vents 41, and the coal powder can be left in the tank. In the utility model, the single-pipe filter drum is improved into the sleeve double-pipe filter drum, therefore, the filter area can be increased manifold, the filter effect is good, the relief and pressure releasing speed is fast, the relief bearing pressure is big, the operation is safe and reliable, the sleeve relief filter is not easy to be deformed and damaged,and the service life is long.
Description
Technical field
The utility model relates to the fluidisation winding-up jar corollary apparatus in a kind of pulverized coal injection powder craft, particularly a kind of telescopic filter that diffuses.
Background technology
In blast-furnace coal powder injection technology, when guaranteeing that fluidisation winding-up jar is diffused release, when gas is diffused away, coal dust is stayed in the jar, in order to avoid contaminated environment, wearing and tearing pipeline, increase cost, need install additional and diffuse filter, the filter that adopts is the single hose cartridge filter at present, its structure comprises cartridge filter and the screen pack end plate 4 (as shown in Figure 1) that adpting flange 1, connecting cylinder 2 and screen pack 3 are formed, its weak point is that filter area is little, weak effect, release speed is slow, bears that to diffuse pressure little, yielding damage, service life is short.
Summary of the invention
The purpose of this utility model is in order to overcome the above-mentioned weak point of prior art, and a kind of good filtration effect is provided, and it is fast to diffuse release speed, the telescopic filter that diffuses of long service life.
The purpose of this utility model is achieved in that the telescopic inner filtration tube that filter comprises cartridge filter, screen pack end plate, interior connecting cylinder and inner filtration net composition that mounting flange, connecting cylinder and screen pack are formed that diffuses; One end of cartridge filter and inner filtration tube is connected with adpting flange, and the other end is connected with the screen pack end plate, and the inner filtration tube is positioned at cartridge filter, and cavity is arranged between the two; Air admission hole is arranged on the adpting flange, and air admission hole is between cartridge filter and inner filtration tube; On the screen pack end plate steam vent is arranged, the size of the size of steam vent and inner filtration tube adapts.
Screen pack and inner filtration are respectively equipped with stiffening ring on the net.
The utility model is owing to adopt above architecture advances, the single hose cartridge filter is improved to telescopic double pipe structure, filter area is multiplied, good filtration effect, it is fast to diffuse release speed, bears that to diffuse pressure big, and add stiffening ring in inside and outside cartridge filter outside, safety and reliability is difficult for deformed damaged, long service life.
Description of drawings
Fig. 1 is the structural representation of existing single hose cartridge filter;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the left view of Fig. 2.
The specific embodiment
Now illustrated embodiment is made detailed description to the utility model in conjunction with the accompanying drawings.
Shown in Fig. 2-3, telescopicly diffuse the inner filtration tube that cartridge filter, screen pack end plate 4, interior connecting cylinder 5 and inner filtration net 6 that filter comprises that mounting flange 1, connecting cylinder 2 and screen pack 3 are formed are formed; One end of cartridge filter and inner filtration tube is connected with adpting flange 1, and the other end is connected with screen pack end plate 4, and the inner filtration tube is positioned at cartridge filter, and cavity is arranged between the two; Air admission hole 11 is arranged on the adpting flange 1, and air admission hole 11 is between cartridge filter and inner filtration tube; Steam vent 41 is arranged on the screen pack end plate 4, and the size of the size of steam vent 41 and inner filtration tube adapts; Be respectively equipped with stiffening ring 7 on screen pack 3 and the inner filtration net 6.During work, coal dust in the winding-up jar and admixture of gas are in air admission hole 11 enters cavity between the inside and outside cartridge filter, part gas diffuses away by outer screen pack 3, and another part gas diffuses away through steam vent 41 by inner filtration net 6, and coal dust is then stayed in the jar.
