Abstract
The utility model discloses a kind of shoes, it includes air preheater pipe, air preheater tube sheet, fixing pipe, Antiwear casing.It is characterized in that fixing pipe is welded on the tube sheet of air preheater, then Antiwear casing is inserted directly into fixing pipe during the installation process, this structure installation is fairly simple, mainly Antiwear casing replacement is more convenient, since Antiwear casing is very more in the quantity of boiler, Antiwear casing is replaced after boiler operatiopn for a period of time, therefore, rapidly Antiwear casing can be extracted out from fixing pipe in this shoe replacement process, it does not need to remove castable refractory, as long as the Antiwear casing of replacement is inserted into.The structure of this shoe significantly shortens the problem of replacement Antiwear casing, reduces the labor intensity of site examining and repairing work, can improve the economic benefit of power plant in a short time by boiler startup.
Description
Technical field
The utility model relates to a kind of air preheater accessories, and in particular to a kind of shoe.
Background technique
In the structure of the abrasionproof of conventional boiler air preheater, the Antiwear casing of boiler is all to put in air preheater
Pipe in, then directly by Socket welding on air preheater tube sheet, one layer of refractory concrete is poured on tube sheet top again.It is detailed in figure
The Antiwear casing of 1 this structure, as the vulnerable part in boiler, quick abrasion, replacement is more frequent, and casing once needs replacing,
It has to all dig out the refractory concrete on upper layer, then Antiwear casing is cut out, by new Antiwear casing insertion, welding, most
One layer of refractory concrete is poured again on top afterwards.
Summary of the invention
In order to solve the above-mentioned technical problem, the utility model provides a kind of shoe, solves boiler due to replacement
Casing and the boiler operation time delayed, reduce the labor intensity of site examining and repairing work, can in a short time by boiler startup,
Improve the economic benefit of power plant.
The utility model adopts the following technical solution: a kind of shoe, including air preheater pipe, air preheater
Tube sheet, fixing pipe, Antiwear casing, air preheater tube sheet intermediate point weld fixing pipe, and fixing pipe inner sleeve connects Antiwear casing, wearing bush
Air preheater pipe is connect below pipe, refractory concrete is poured in air preheater tube sheet two sides air preheater tube sheet upper end,
The refractory concrete is poured not to be spilt in fixing pipe two sides.
The diameter of the fixing pipe is 60mm, thick 4mm.
The diameter of the Antiwear casing is 51mm, thick 2mm.
The utility model has the advantage that: installation is fairly simple, and mainly Antiwear casing replacement is more convenient, due to abrasionproof
Casing is very more in the quantity of boiler, to replace to Antiwear casing after boiler operatiopn for a period of time, therefore, this abrasionproof
Device does not need to remove castable refractory, as long as the Antiwear casing after abrasion is extracted out from fixing pipe, by the wearing bush of replacement
Pipe insertion.The structure of this shoe has well solved the replacement problem of Antiwear casing, greatly reduces boiler
The time is repaired, the labor intensity of site examining and repairing work is reduced, the warp of power plant can be improved in a short time by boiler startup
Ji benefit.
Detailed description of the invention
Fig. 1 is place where troops were originally stationed mill structural schematic diagram.
Fig. 2 is the structural schematic diagram of the utility model.
Description of symbols: 1. air preheater pipes, 2. air preheater tube sheet, 3. fixing pipe, 4. Antiwear casings, 5.
Refractory concrete.
Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
Please refer to attached drawing 1, Fig. 2, a kind of shoe, including air preheater pipe (1), air preheater tube sheet (2),
Fixing pipe (3), Antiwear casing (4), air preheater tube sheet (2) intermediate point weld fixing pipe (3), and fixing pipe (3) inner sleeve takes over control mill
Casing (4), Antiwear casing (4) lower section connect air preheater pipe (1), air preheater tube sheet (2) the two sides air preheat
Device tube sheet (2) upper end is poured refractory concrete (5), and the refractory concrete (5) is poured not to be spilt in fixing pipe (3) two sides.
The diameter of the fixing pipe (3) is 60mm, thick 4mm.
The diameter of the Antiwear casing (4) is 51mm, thick 2mm.
The utility model has the advantage that: installation is fairly simple, and mainly Antiwear casing (4) replacement is more convenient, due to
Antiwear casing (4) is very more in the quantity of boiler, to replace to Antiwear casing (4) after boiler operatiopn for a period of time, because
This, this shoe does not need to remove castable refractory, as long as the Antiwear casing (4) after abrasion is taken out from fixing pipe (3)
Out, the Antiwear casing of replacement (4) are inserted into.The structure of this shoe has well solved Antiwear casing (4) more
Change problem, greatly reduce boiler maintenance and repair the time, reduce the labor intensity of site examining and repairing work, can in a short time by
Boiler startup improves the economic benefit of power plant.
Not limited to this, any change or replacement expected without creative work should all be covered in the utility model
Protection scope within.Therefore, the protection scope of the utility model should be determined by the scope of protection defined in the claims.
