Abstract
The utility model provides a sealing mechanism for sealing a rear wall exhaust tube and suspension tube water-cooling wall penetrated by a smoke deflecting corner water-cooling wall. The sealing mechanism is characterized by comprising a first sleeve and a second sleeve, the first sleeve and the second sleeve are respectively sleeved on the outsides of portions, which are penetrated by a rear wall exhaust tube and a suspension tube, of the smoke deflecting corner water-cooling wall, a first comb-shaped edge folding plate and a second comb-shaped edge folding plate are located on the left side and the right side of the rear wall exhaust tube and suspension tube water-cooling wall, one side of the first comb-shaped edge folding plate and one side of the second comb-shaped edge folding plate are connected with fins of the smoke deflecting corner water-cooling wall, the other side of the first comb-shaped edge folding plate and the other side of the second comb-shaped edge folding plate are connected with the first sleeve and the second sleeve, and a first comb-shaped plate and a second comb-shaped plate are respectively connected to two ends of the first comb-shaped edge folding plate and two ends of the second comb-shaped edge folding plate. The sealing mechanism has the advantages that 1, the problem of sealing of the rear wall exhaust tube and suspension tube water-cooling wall penetrated by the smoke deflecting corner water-cooling wall is effectively resolved, high-temperature smoke is prevented from leaking outwards or cold air is prevented from entering a boiler, and operation stability and thermal efficiency of the boiler are improved, and 2, the sealing mechanism is simple in structure and manufacture and convenient in construction.
Description
Technical field
The utility model relates to the sealing mechanism that a kind of back wall coil and column pipe water-cooling wall are worn the smoke folded angle water-cooling wall.
Background technology
In certain type boiler, smoke folded angle water-cooling wall 8 is relatively independent system, and itself and furnace wall cooling 10 concern as shown in Figure 1 with the positioned opposite that afterwards coats 9.Fig. 2 is the enlarged drawing of I part among Fig. 1, as shown in Figure 2, back wall coil 11 in a row passes smoke folded angle water-cooling wall 8 with column pipe 12 at position I place, smoke folded angle water-cooling wall 8 is jumped pipe herein and is dodged, owing to do not seal, therefore, high-temperature flue gas is outwards revealed easily at this place, and cold air also pours in down a chimney in the stove easily, brings influence for like this stability and the thermal efficiency of boiler operatiopn.
Summary of the invention
The purpose of this utility model provides a kind of structure that back wall coil and column pipe water-cooling wall are worn smoke folded angle water-cooling wall place sealing problem that solves.
In order to achieve the above object, the technical solution of the utility model has provided the sealing mechanism that a kind of back wall coil and column pipe water-cooling wall are worn the smoke folded angle water-cooling wall, it is characterized in that: comprise first sleeve and second sleeve, first sleeve and second sleeve are set in the back wall coil respectively and column pipe passes outside the position of smoke folded angle water-cooling wall, a side of the first comb shape flanged plate of the wall coil and the column pipe water-cooling wall left and right sides and the second comb shape flanged plate connects the fin of smoke folded angle water-cooling wall after being positioned at, another side connects first sleeve and second sleeve, first dredges shape plate and second dredges the two ends that the shape plate is connected to the first comb shape flanged plate and the second comb shape flanged plate, the first comb shape flanged plate, the second comb shape flanged plate, the first thin shape plate and second is dredged the shape plate and has been formed a sealing box type structure jointly.
Further, on the first comb shape flanged plate and the second comb shape flanged plate, be coated with shrouding, with the gap of sealing column pipe.
The utility model has the advantages that: 1, effectively solve back wall coil and column pipe water-cooling wall and wear the sealing problem at smoke folded angle water-cooling wall place, prevent that high-temperature flue gas from outwards revealing or cold air pours in down a chimney in the stove, improve the stability and the thermal efficiency of boiler operatiopn; 2, structure fabrication is simple, easy construction.

The specific embodiment
For the utility model is become apparent, now with a preferred embodiment, and conjunction with figs. is described in detail below.
As shown in Figures 3 and 4, the sealing mechanism that a kind of back wall coil that provides for the utility model and column pipe water-cooling wall are worn the smoke folded angle water-cooling wall, comprise first sleeve 1 and second sleeve 2, first sleeve 1 and second sleeve 2 are set in back wall coil 11 respectively and column pipe 12 passes outside the position of smoke folded angle water-cooling wall 8, a side of the first comb shape flanged plate 5 of the wall coil 11 and column pipe 12 left and right sides and the second comb shape flanged plate 6 connects the fin of smoke folded angle water-cooling wall 8 after being positioned at, another side connects first sleeve 1 and second sleeve 2, first dredges shape plate 3 and second dredges the two ends that shape plate 4 is connected to the first comb shape flanged plate 5 and the second comb shape flanged plate 6, the first comb shape flanged plate 5, the second comb shape flanged plate 6, the first thin shape plate 3 and second is dredged shape plate 4 and has been formed a sealing box type structure jointly.
Further, for prevent that the gap location of flue gas between two column pipes 12 from revealing and cold air in pour in down a chimney in the stove herein, so be covered on the first comb shape flanged plate 5 and the second comb shape flanged plate 6 with shrouding 7 herein.
Adopt sleeve in the utility model, dredge shape plate, comb shape flanged plate and shrouding, form the class structure of seal box, be arranged in each back wall coil and tube bank place of column pipe water-cooling wall, can effectively solve back wall coil and column pipe and wear the sealing problem at smoke folded angle water-cooling wall place.
