Abstract
The utility model provides a sealing mechanism between forge pieces at a junction of a smoke deflecting corner water-cooling wall and a hearth back wall water-cooling wall, which is characterized in that the sealing mechanism comprises a flanged plate; the flanged plate covers at least one non-fire-facing surface or a fire-facing surface at the junction of the smoke deflecting corner water-cooling wall and the hearth back wall water-cooling wall; the shapes of two side flanged edges of the flanged plate adapt to the shape of the non-fire-facing surface or the fire-facing surface; and the two side flanged edges of the flanged plate are respectively connected with the smoke deflecting corner water-cooling wall and the hearth back wall water-cooling wall by a sealing fixing device. The sealing mechanism has the advantages that the sealing problem between the forge pieces at the junction of the smoke deflecting corner water-cooling wall and the hearth back wall water-cooling wall is effectively solved, so that high-temperature fume is prevented from being leaked outwards or cold air is prevented from being inversely infused into a boiler, and the running stability and the heat efficiency of the boiler are improved.
Description
Technical field
The utility model relates to the sealing mechanism between a kind of smoke folded angle water-cooling wall and burner hearth rear water wall infall forging.
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 afterwards coats 2, Fig. 2 is the enlarged drawing of I part among Fig. 1, in conjunction with Fig. 1 and Fig. 2 as can be known, adopt forging to realize intersecting mutually between smoke folded angle water-cooling wall 1 and the burner hearth rear water wall 3, there is the gap between the forging, can cause high-temperature flue gas outwards to reveal like this or cold air pours in down a chimney in the stove, the stability of boiler operatiopn and the thermal efficiency be caused have a strong impact on.
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 water-cooling wall and burner hearth rear water wall infall forging.
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 water-cooling wall and burner hearth rear water wall infall forging, it is characterized in that: comprise flanged plate, flanged plate covers at least one non-side towards the fire or side towards the fire of smoke folded angle water-cooling wall and burner hearth rear water wall infall, two side edgefold shapes of flanged plate adapt with the shape of this non-side towards the fire or side towards the fire, and two side edgefolds of flanged plate link to each other with smoke folded angle water-cooling wall and burner hearth rear water wall by a sealed fixing device respectively.
Further, described sealed fixing device is a comb plate, comb joint.
The utility model has the advantages that: effectively solve the sealing problem between smoke folded angle water-cooling wall and burner hearth rear water wall infall forging, 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.
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;
A kind of smoke folded angle water-cooling wall that Fig. 3 provides for the utility model and the sealing mechanism schematic diagram between burner hearth rear water wall infall forging.
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, a kind of smoke folded angle water-cooling wall that provides for the utility model and the sealing mechanism between burner hearth rear water wall infall forging, comprise flanged plate 5, flanged plate 5 covers at least one non-side towards the fire or side towards the fire of smoke folded angle water-cooling wall 1 and burner hearth rear water wall 3 infalls, in the present embodiment, flanged plate 5 covers respectively on three faces, two side edgefold shapes of flanged plate 5 adapt with the shape of this non-side towards the fire or side towards the fire, and two side edgefolds of flanged plate 5 link to each other with smoke folded angle water-cooling wall 1 and burner hearth rear water wall 3 by a comb plate, comb joint 4 respectively.
Because smoke folded angle water-cooling wall 1 is the membrane type structure with burner hearth rear water wall 3, connect into pipe row by band steel between the pipe, therefore adopt comb plate, comb joint 4 can realize fitting tightly, thereby reach the purpose of sealing, again flanged plate 5 is connected on the comb plate, comb joint 4.
Claims (2)
1. the sealing mechanism between smoke folded angle water-cooling wall and burner hearth rear water wall infall forging, it is characterized in that: comprise flanged plate (5), flanged plate (5) covers at least one non-side towards the fire or side towards the fire of smoke folded angle water-cooling wall (1) and burner hearth rear water wall (3) infall, two side edgefold shapes of flanged plate (5) adapt with the shape of this non-side towards the fire or side towards the fire, and two side edgefolds of flanged plate (5) link to each other with smoke folded angle water-cooling wall (1) and burner hearth rear water wall (3) by a sealed fixing device respectively.
2. the sealing mechanism between a kind of smoke folded angle water-cooling wall as claimed in claim 1 and burner hearth rear water wall infall forging is characterized in that: described sealed fixing device is comb plate, comb joint (4).
