Utility model content
The purpose of this utility model is to provide a kind of a kind of mounting structure of inlaying brick cast-iron cooling wall fast simple in structure, easy for installation.
For achieving the above object, technical scheme provided by the utility model is a kind of mounting structure of inlaying brick cast-iron cooling wall, edge brick cast-iron cooling wall is positioned at the inner side of furnace shell, cooling stave water pipe on edge brick cast-iron cooling wall is through the perforate on furnace shell, it is characterized in that: it comprises the first set collar and coal gas seal closure, on the protective casing of described the first Fixing shrink ring on cooling stave water pipe, the outer wall seal welding of the first set collar and protective casing and furnace shell; On every edge brick cast-iron cooling wall, there is more than one pair of cooling stave water pipe, wherein at least one cooling stave water pipe, described the first set collar is installed; On other cooling stave water pipes, all cover has coal gas seal closure, the outer wall seal welding of coal gas seal closure and cooling stave water pipe and furnace shell.
On every edge brick cast-iron cooling wall, have four pairs of cooling stave water pipes, the distribution of cooling stave water pipe two row four row, is wherein provided with described the first set collar on two cooling stave water pipes in the middle of lower row.
It also comprises the second set collar, on the protective casing of the second Fixing shrink ring on cooling stave water pipe, and is positioned at coal gas seal closure; Described the second set collar and protective casing welding, and contact with the outer wall of furnace shell.
Described the first set collar and the second set collar are a doughnut-shaped steel plate, and it has suitable internal diameter, external diameter and thickness, and possess enough intensity.
In technique scheme, the outer wall seal welding of the first set collar and protective casing and furnace shell is in order to prevent that in stove, coal gas leaks.
In technique scheme, the outer wall seal welding of coal gas seal closure and cooling stave water pipe and furnace shell is in order to prevent that in stove, coal gas leaks.
The second described set collar only with protective casing firm welding, the second set collar and furnace shell do not weld; Can free expansion after being heated to guarantee to inlay brick cast-iron cooling wall and furnace shell, and unlikelyly cause cooling stave water pipe to be cut off to occur run-down phenomenon.
The beneficial effects of the utility model:
1, the utility model has been cancelled the nut that is cast into of edge brick cast-iron cooling wall, has reduced the casting difficulty of cooling stave; Cooling stave by the first set collar and the second set collar directly and furnace shell carry out fasteningly, without additionally offer a large amount of bolt mounting holes on furnace shell, improved the resistance to overturning of furnace shell; Of the present utility model simple in structure, easy for installation quick;
2, in the utility model the second set collar only with protective casing firm welding; edge brick cast-iron cooling wall and furnace shell are not retrained and free expansion each other after being heated, can from basic solution, because inlaying, brick cast-iron cooling wall is different from the temperature difference between furnace shell to be caused water pipe to be cut off occurring run-down phenomenon.
