Abstract
The invention relates to a method for mounting a dust settling flue of a sintering chamber. The method includes steps of (1), integrally manufacturing a flue body 1 and a bottom air box 3 of the flue body 1; (2), integrally mounting the flue body and the bottom air box of the flue body; (3), mounting a dust collecting hopper. The method has the advantages that the flue body and the bottom air box of the flue body are integrally manufactured by a mounting process, two mounting procedures replace the original four mounting procedures, and accordingly mounting safety risks can be reduced; the mounting procedures can be carried out alternately, and the dust collecting hopper can be mounted after a part of the flue body is completely mounted; a hole is formed in the bottom of the flue when the flue body and the bottom air box of the flue body are integrally manufactured, cut steel plates can be used on other components after being processed by a processing plant, and accordingly steel plates can be saved.
Description
Technical field
The invention belongs to flue dust's construction field, flue dust of especially a kind of agglomerating chamber installation method.
Background technology
In Sinter Machines Project, flue dust is one of capital equipment of agglomerating chamber's depositing dust recovery.The concrete frame Shang， flue dust agent structure that this flue dust is positioned at agglomerating chamber comprises bellows and the flue-dust retainer of flue body, flue body bottom.Traditional installation method step is: the installation of flue body, flue body bottom opening, flue body bottom bellows are installed, flue-dust retainer is installed, and the method continues into the present at metallurgy industry always.The weak point of the method: 1, installation procedure is many, increases the security risk of installing; 2, every procedure can not intert installation, and the whole installations of a procedure, just can carry out next process; 3, during flue body bottom opening, fabrication completes, and a large amount of steel plates that cut down do not have the place that utilizes, can only work as waste disposal; 4, construction cost is large; 5, long in time limit.
Summary of the invention
The object of the invention is to overcome prior art deficiency, flue dust of a kind of agglomerating chamber installation method is provided, the method technique is simple, reduce operation, reduce costs, the construction period is short, safe.
The present invention solves its technical problem and is achieved through the following technical solutions:
Flue dust of an agglomerating chamber installation method, the step of its installation method is as follows:
(1), flue body and bottom bellows integral manufacturing thereof: by 2 interim conduit saddles, position, super flat, check and adjust concentricity, interim conduit saddle is carried out to reinforcement of weld, then flue body is hung on conduit saddle, cross messenger wire measured center, adjust the position that checks flue body, on flue body, find out longitudinal centre line, throw the contact wheel profile of surveying bellows, throw and survey flue perforate outline line, bellows are inverted to 180 ° to be arranged on flue body, through measuring, levelling, centering, gap is adjusted, four jiaos of lock welderings, after centre is symmetrically welded and fixes, start the flue body of bellows one side to carry out gas cutting perforate,
(2), flue body and bottom bellows integral installation thereof: adopt crane to add the installation method of guide chain, by flue body, turn to, draw high, draw, parallel is to design attitude, flue body slowly lands, the axis that guarantees each axis and flue body coincides, meanwhile, with spirit level, check flue body bottom bellow port levelness, reach code requirement;
(3), flue-dust retainer installs: adopt crane to add jack and install, flue-dust retainer is lifted on the position of connection of bellows, by measuring after centering, carry out counterpart installation, flue dust of agglomerating chamber installs.
Above-mentioned gap adjustment adopts jack to draw receipts.
The distance of four jiaos of above-mentioned lock welderings is 150mm.
Advantage of the present invention and beneficial effect are:
In the present invention, the bellows of flue body and bottom thereof adopt integral manufacturing mounting process, and installation procedure is reduced to two procedures by four procedures, and the security risk of installation reduces.Installation procedure can intert and carries out, and the installation of part flue body, just can install flue-dust retainer, the bellows of flue body and bottom thereof are when integral manufacturing, and flue bottom is with regard to perforate, the steel plate cutting down, in processing factory after treatment, be used on other member, saved steel plate.The steel plate that flue bottom opening cuts down, often opens a hole by 19m
2calculate, steel plate 1.49t is saved in a hole.According to 13 sections of flue body perforates, calculate, save steel plate 19.37t.Installation period can be saved about 20 days.Construction cost is reduced greatly, and the steel plate that gas cutting gets off after treatment, is used as other positions such as lower hawk.
Accompanying drawing explanation
Fig. 1 is flue structure schematic diagram of the present invention;
Fig. 2 is flue body of the present invention and bellows assembly drawing.
The specific embodiment
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
Flue dust of an agglomerating chamber installation method, the step of its installation method is as follows:
(1), flue body 1 and bottom bellows 3 integral manufacturings thereof: on steel platform 6 by 2 interim conduit saddles 5, position, super flat, check and adjust concentricity, interim conduit saddle is carried out to reinforcement of weld, then flue body is hung on conduit saddle, cross messenger wire measured center, adjust the position that checks flue body, on flue body, find out longitudinal centre line, throw the contact wheel profile of surveying bellows, throw and survey flue perforate outline line, bellows are inverted to 180 ° to be arranged on flue body, through measuring, levelling, centering, gap is adjusted, gap adjustment adopts jack to draw receipts, four jiaos of lock welderings, the distance of four jiaos of lock welderings is 150mm, after centre is symmetrically welded and fixes, start the flue body of bellows one side to carry out gas cutting perforate 2,
(2), flue body and bottom bellows integral installation thereof: adopt crane to add the installation method of guide chain, by flue body, turn to, draw high, draw, parallel is to design attitude, flue body slowly lands, the axis that guarantees each axis and flue body coincides, meanwhile, with spirit level, check flue body bottom bellow port levelness, reach code requirement;
(3), flue-dust retainer installs: adopt crane to add jack and install, flue-dust retainer 4 is lifted on the position of connection of bellows, by measuring after centering, carry out counterpart installation, flue dust of agglomerating chamber installs.
