Abstract

The utility model relates to an aluminium alloy garland punched with one plate, comprising an inner ring and an outer ring which are integrally formed with one plate material. The inner ring and the outer ring are connected with ribs which are arranged between the inner ring and the outer ring. The utility model is characterized in that each of the ribs is composed of an upper half circular ring rib and a lower half circular ring rib. Each two contiguous ribs are formed by that upper half circular ring ribs and lower half circular ring ribs are staggeringly arranged. The utility model has the advantages of big specific surface area and light unit weight. The aluminium alloy garland punched with one plate can not be deformed the mediums below 300 DEG C. As a filler, the aluminium alloy garland punched with one plate can be used for a long time, so that mechanical water in coal gas is deprived to 7g/Nm 3. The aluminium alloy garland punched with one plate can be used for a dehydrator in cleaning blast furnace gas in iron and steel factory, and can also be used in a filler tower in a chemical plant.

Description

Aluminium alloy garland with a plate punching press system

The utility model relates to a kind of filler, is the aluminium alloy garland of a plate punching press system of a kind of usefulness specifically, is mainly used in during the steel plant blast furnace gases cleans, and removes in the dehydrator of mechanical water droplet in the coal gas and dust.

Filler in the dehydrator that blast furnace gas cleans in past and the present steel plant, all use the polypropylene garland always, it includes outer shroud and interior ring, and be connected with muscle at two interannulars, because garland is to be formed by the polypropylene material casting, therefore above-mentioned interior ring and outer shroud and muscle in same plane, are plates basically.Need during use on packing layer and below use expanded metal lath, the expanded metal lath below utilizing holds up the plastics garland, utilizes top expanded metal lath to prevent that coal gas from blowing away garland.But the temperature tolerance of this filler is poor, the temperature height can the distortion, when 60 ℃ of left and right sides of blast furnace gas, or purging system is during with purge vapor coal gas, the height and the diameter of polypropylene garland diminish, and pass the upper strata expanded metal lath thereby often carried by coal gas stream, flow out dehydrator with coal gas, this just makes dehydrator lose the function of taking off mechanical water, often causes the mechanical water content in the coal gas to reach 100g/Nm ³More than, and the coal gas that contains many like this water usually makes the refractory brick of hot-blast stove portion crack damage owing to chilling, and hot blast temperature can not burn, and also can influence blast furnace production.

The purpose of this utility model is to provide the aluminium alloy garland of a plate punching press system of a kind of usefulness, increases the intensity of filler, increases specific area, alleviate Unit Weight, corrosion-resistant, antirust, and use is indeformable in the medium temperature below 300 ℃, prolongs its service life.

The purpose of this utility model is achieved in that the aluminium alloy garland of a plate punching press system of a kind of usefulness, include by an one-body molded interior ring of sheet material and outer shroud, be connected with muscle between ring and the outer shroud in being somebody's turn to do, it is characterized in that described muscle is to be made of first annulus muscle and second annulus muscle, per two adjacent muscle are staggered by first annulus muscle and second annulus muscle.

The purpose of this utility model also can be realized that by following measure the outer ring of described outer shroud is provided with one and has the annulus of certain width, and is crest and trough shape, and this outer ring annulus is to be formed by the turnover of outer shroud edge.Thickness 1～the 1.5mm of sheet material is that it is 30mm, 50mm, 75mm, 100mm that garland has outer shroud to can be made into external diameter.

It is significant that the utility model is compared effect with prior art, because the utility model is to adopt an aluminium alloy plate to be stamped to form, therefore has fabulous mechanical strength, need not weld, and the saving material, than aluminium alloy garland labor and material saving and the smooth surface that casting is made, low cost of manufacture.And it is big to have specific area, and bulk density is light, corrosion-resistant, antirust, and use is indeformable in the medium temperature below 300 ℃, can use for a long time as the filler in the dehydrator.Experiment showed, that the utility model can be removed to 7g/Nm to the mechanical water in the blast furnace gas ³Because mechanical water content is few in the coal gas, thereby can improve the hot blast temperature of blast furnace, reduce the coke consumption of ironmaking, reduce cost, thereby reach the purpose of this utility model.

The explanation of accompanying drawing drawing:

Fig. 1 structural representation of the present utility model;

Fig. 2 A-A profile of the present utility model.

It is as follows to describe the utility model in detail below in conjunction with embodiment and accompanying drawing thereof;

See also shown in Figure 1, the utility model includes ring 1 and outer shroud 2 in one, the uniform muscle 3 that is provided with of equal angles between interior ring 1 and outer shroud 2, and the outer ring of its outer shroud 2 is provided with an annulus 21 with certain width, this outer ring annulus 21 is crest and trough shape, and not in same plane.Annulus 21 is to be formed by the turnover of the limit of outer shroud 2, thereby increases the rigidity of garland.It is 30～100mm different size that garland of the present utility model can be made into external diameter, uses with the dehydrator that is adapted to different size.

The muscle 3 of ring 1 and outer shroud 2 is made of first annulus muscle 31 and second annulus muscle 32 in above-mentioned being connected in, and per two adjacent muscle 3 are staggered by first annulus muscle 31 and second annulus muscle 32, and not in same plane.For example in the present embodiment, the label among Fig. 1 is that the muscle 3 of odd number is to be bent upwards, and presents semicircular ring 31, as shown in Figure 2; And the label among Fig. 1 is the muscle 3 of even number is to be bent downwardly, and is second annulus 32.

The utility model garland is to adopt the thick aluminum alloy plate materials integrated punching of 1～1.5mm to form.Because its structure is different from the characteristics of other filler, when it is contained in the dehydrator, be between the filler or between filler and the wall and contact, its space is even, drag losses is little, and coal gas or other gas flow are big, can not stopped up by the dust in the coal gas, available water flushing packing layer also in case of necessity has the mechanical water of collection and is the function of mechanical water water conservancy diversion; Owing to the utlity model has resistant to elevated temperatures characteristic, so also in the absorption tower or packed tower applicable to high temperature in the chemical industry, as the element of heat transfer medium.
