Description
Technical field
This utility model relates to the adnexa of waste heat boiler, the cover mounting structure of a kind of waste heat boiler.
Background technology
Waste heat boiler, as the term suggests the heat produced after referring to utilize the waste heat in waste gas, waste material or the waste liquid in various industrial process and combustible burning thereof is heated to water in the boiler of certain working medium.Have smoke box, oil burning boiler that flue residue heat recycles, gas fired-boiler, coal-burning boiler are also referred to as waste heat boiler, and waste heat boiler can produce hot water by waste heat recovery or steam supplies other workshop section and uses.
The basic functional principle of waste heat boiler is: fuel oil, combustion gas, the coal-fired burning generation high-temperature flue gas that passes through discharge heat, high-temperature flue gas is introduced into burner hearth, enter back into the waste-heat recovery device of front smoke box, subsequently enter smoke-fire-tube, finally entering the waste-heat recovery device in rear smoke box flue, high-temperature flue gas becomes low-temperature flue gas and enters air through chimney.Greatly increase the utilization rate of the heat of fuel combustion release due to waste heat boiler, there is the effect saving the energy, be therefore widely popularized use.
Its outside of existing waste heat boiler is provided with backplate more, existing cover mounting structure is as shown in Figure 3, its backplate 4 is directly connected with column 1 by angle steel 6, so in waste heat boiler running, heat on backplate directly will be transferred to column 1 by angle steel 6, so can cause overtemperature at furnace outer wall especially stove column 1, even can cause coming off of inner casing time serious, cause boiler supports structural strength to be affected；Therefore its structure is further improved.
Summary of the invention
Technical problem to be solved in the utility model is the present situation for prior art, it is provided that simple in construction, it is possible to avoid heat directly to transmit to column, it is to avoid the cover mounting structure of a kind of waste heat boiler of overtemperature at column.
The technical scheme that the above-mentioned technical problem of this utility model solution is used is:
A kind of cover mounting structure of waste heat boiler, include column, it is connected to crossbeam in two adjacent side of column, the transition piece extended internally it is respectively fixed with on crossbeam, the medial extremity of the transition piece arranged at same column connects fixing, it is fixed with backplate on the medial surface of transition piece, between backplate and described column, is formed with cavity.
The technical measures optimized also include:
The medial extremity of above-mentioned transition piece is fixed by Bolted angle connection, and the lateral surface of angle steel is close to mutually with corresponding transition piece respectively.
Gap is left between above-mentioned backplate and described angle steel.
It is provided with thermal insulation layer between side and the described crossbeam of above-mentioned column.
Above-mentioned transition piece is channel-section steel.
The cover mounting structure of a kind of waste heat boiler of this utility model, by the transition piece extended internally fixing on crossbeam, thus the installation site of backplate is extended internally, make to be formed with between backplate and column cavity by the ingehious design of this simple structure, this cavity not only avoids direct heat transmission between backplate and column, and contribute to aeration-cooling, effectively reduce the heat being transferred to column in waste heat boiler running, avoid column overheated and cause the impact on waste heat boiler structural strength, and then ensure that the stable operation of waste heat boiler and use safety.
It addition, leave gap between backplate and angle steel, not only it is reduced as far as heat transfer contact face, thus reduces the heat transmission to column, and facilitate the welding of angle steel, backplate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is A portion enlarged drawing in Fig. 1；
Fig. 3 is existing cover mounting structure.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
It is structural representation of the present utility model as shown in Figure 1 to Figure 2,
Reference therein is: column 1, thermal insulation layer 11, crossbeam 2, transition piece 3, backplate 4, gap 4a, cavity 5, angle steel 6.
As shown in Figure 1 to Figure 2,
A kind of cover mounting structure of waste heat boiler, include column 1, it is connected to crossbeam 2 in two adjacent side of column 1, the transition piece 3 extended internally it is respectively fixed with on crossbeam 2, the medial extremity of the transition piece 3 arranged at same column 1 connects fixing, it is fixed with backplate 4 on the medial surface of transition piece 3, between backplate 4 and described column 1, is formed with cavity 5.
An angle for cover mounting structure shown in Fig. 1, whole cover mounting structure is a rectangle, and the cover mounting structure at its excess-three angle is same as shown in Figure 1；Transition piece 3 and backplate 4 are mounted on the inner side of rectangular configuration.
In embodiment, the medial extremity of transition piece 3 connects fixing by angle steel 6, and the lateral surface of angle steel 6 is close to corresponding transition piece 3 phase respectively.By the fixing hermetic seal that ensure that at cavity 5 of angle steel 6, the beneficially raising of ventilation effect.
Use angle steel 6 to fix the medial extremity of transition piece 3, draw materials conveniently, low cost of manufacture；And the lateral surface of angle steel 6 can be utilized as supporting surface, by the lateral surface of angle steel 6, end face with corresponding transition piece 3 is close to mutually respectively, it is possible to be effectively improved support strength.
In embodiment, between backplate 4 and described angle steel 6, leave gap 4a.
The gap 4a reserved avoids directly contact between backplate 4 with angle steel 6, thus reduces the heat transfer between backplate 4 and angle steel 6, effectively reduces heat transfer area, further the minimizing heat transmission to column 1, it is to avoid column 1 overheated.It addition, arrange gap 4a to be also convenient for being welded and fixed between angle steel 6, backplate 4 and transition piece 3.
In embodiment, between side and the described crossbeam 2 of column 1, it is provided with thermal insulation layer 11.Thermal insulation layer 11 is set and can reduce the heat transmission to column 1 further, be more beneficial for the protection of column 1.
In embodiment, transition piece 3 is channel-section steel.Use channel-section steel as transition piece 3, draw materials conveniently, low cost of manufacture；It addition, the cross section of channel-section steel is Contraband character form structure, this structure contributes to the raising of overall construction intensity.
The cover mounting structure of this utility model waste heat boiler, by the transition piece 3 extended internally fixing on crossbeam 2, thus the installation site of backplate 4 is extended internally, make to be formed with between backplate 4 and column 1 cavity 5 by the ingehious design of this simple structure, thus avoid direct heat transmission between backplate 4 and column 1, additionally, arrange cavity 5 also have aeration-cooling effect, contribute to the reduction of column 1 temperature；While utilizing angle steel 6 to strengthen transition piece 3 bonding strength, gap 4a is left between backplate 4 and angle steel 6, avoid directly contacting between backplate 4 with angle steel 6, reduce heat transfer area, thus effectively reduce in waste heat boiler running the heat of backplate 4 to the transmission of column 1, avoid column 1 overheated and cause the impact on waste heat boiler structural strength, and then ensure that the stable operation of waste heat boiler and use safety.
Most preferred embodiment of the present utility model illustrates, those of ordinary skill in the art the various changes made or remodeling are all without departing from scope of the present utility model.
