Abstract
The utility model provides a seal structure arranged between a furnace arch and the front wall of a rear flue, which is characterized by comprising a seal plate arranged between a furnace arch water-cooling wall and the front wall of the rear flue. Two ends of the seal plate are connected with the furnace arch water-cooling wall and the front wall of the rear flue respectively through a seal fixing device. The seal structure arranged between the furnace arch and the front wall of the rear flue has the advantages that 1 the seal structure effectively resolves the seal problem existing between the furnace arch water-cooling wall and the front wall of the rear flue; and 2 the seal plates can deform to absorb expansion between the furnace arch water-cooling wall and the front wall of the rear flue when relative displacements occur between the furnace arch water-cooling wall and the front wall of the rear flue.
Description
Technical field
The utility model relates to the sealing mechanism between a kind of boiler smoke folded angle and back cigarette well front wall.
Background technology
In certain type boiler, smoke folded angle water-cooling wall 1 is relatively independent system, itself and furnace wall cooling 3 concern as shown in Figure 1 with the positioned opposite that the back coats, Fig. 2 is the enlarged drawing of I part among Fig. 1, in conjunction with Fig. 1 and Fig. 2 as can be known, there is the gap, not sealing between smoke folded angle water-cooling wall 1 and the back cigarette well front wall 2.And, in the actual motion of boiler, have relative displacement between smoke folded angle water-cooling wall 1 and the back cigarette well front wall 2.
Summary of the invention
The purpose of this utility model provides the structure of sealing problem between a kind of thorough solution smoke folded angle and back cigarette well front wall.
In order to achieve the above object, the technical solution of the utility model has provided the sealing mechanism between a kind of smoke folded angle and back cigarette well front wall, it is characterized in that: comprise the sealing plate of being located between smoke folded angle water-cooling wall and the back cigarette well front wall, the two ends of sealing plate link to each other with back cigarette well front wall with the smoke folded angle water-cooling wall by a sealed fixing device respectively.
Further, described sealed fixing device is a comb plate, comb joint, and the end of described sealing plate is connected on the comb plate, comb joint.
Sealing plate is the flanged plate of two lateral bucklings, and two side edgefolds of flanged plate link to each other with a described fixture respectively.
Described flanged plate is a thin plate.
The utility model has the advantages that: 1, effectively solved the sealing problem between smoke folded angle water-cooling wall and the back cigarette well front wall; 2, when between smoke folded angle water-cooling wall and back cigarette well front wall relative displacement taking place, sealing plate can deform thereupon, absorbs therebetween to expand.
Description of drawings
Fig. 1 is the positioned opposite graph of a relation of smoke folded angle water-cooling wall and furnace wall cooling and back coating;
Fig. 2 is the I part enlarged drawing among Fig. 1;
Sealing mechanism schematic diagram between a kind of smoke folded angle that Fig. 3 provides for the utility model and back cigarette well front wall.
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 Figure 3, sealing mechanism between a kind of smoke folded angle that provides for the utility model and back cigarette well front wall, comprise the flanged plate 4 that is arranged on two lateral bucklings between smoke folded angle water-cooling wall 1 and the back cigarette well front wall 2, on smoke folded angle water-cooling wall 1 and back cigarette well front wall 2, a comb plate, comb joint 5 is installed respectively, two side edgefolds of flanged plate 4 link to each other with a comb plate, comb joint 5 respectively, and smoke folded angle water-cooling wall 1 and back cigarette well front wall 2 are close in the distribution of the flanging of flanged plate 4.
Because smoke folded angle water-cooling wall 1 is the membrane type structure with back cigarette well front wall 2, connects into pipe row by band steel between the pipe, therefore adopts comb plate, comb joint 5 can realize fitting tightly, thereby reaches the purpose of sealing, flanged plate 4 is connected on the comb plate, comb joint 5 again.Flanged plate 4 is a thin plate, and when smoke folded angle water- cooling wall 1 and 2 generations of back cigarette well front wall relative displacement, the flanged plate 4 that thin plate is made can deform thereupon, absorbs therebetween to expand.
Claims (4)
