Description

Technical Field

[0001] This utility model relates to the field of combustion chamber shell technology, and more specifically, to a combustion chamber shell. Background Technology

[0002] Combustion chamber shells are key components in many thermal energy devices, such as gas turbines, internal combustion engines, and rocket engines. They not only provide space for the mixing and combustion of fuel and oxidizer, but also protect internal components and transfer heat and mechanical stress. The design and material selection of the combustion chamber shell have a significant impact on the performance, efficiency, and lifespan of the equipment. In some cases, heat exchange structures need to be installed outside the combustion chamber shell to perform heat exchange, thereby achieving purposes such as discharging hot water and cooling. At the same time, excess heat is discharged through the combustion chamber shell.

[0003] Most existing combustion chamber shells are equipped with fixed exhaust pipes. During use, the hot gas after heat exchange is discharged through the fixed pipe. At this time, the hot gas still carries a certain amount of heat. During the exhaust process, the hot gas often concentrates at the bends of the pipe, resulting in more heat being applied to the joints. Depending on the material, the hot gas affects the service life of the pipe, which can easily affect the discharge of hot gas and the normal operation of other equipment.

[0004] In summary, in order to address the issue of concentrated and high-temperature exhaust gas during combustion chamber shell operation, it is necessary to ensure that the combustion chamber shell can uniformly exhaust the hot gas, facilitate cooling, and reduce the impact on other equipment. Utility Model Content

[0005] The present invention provides a combustion chamber shell, which aims to solve the problem that, in the case of existing combustion chamber shells, hot gas tends to concentrate at the bends in the pipes, which can easily affect the emission of hot gas and the normal operation of other equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a combustion chamber shell, including a first shell, a second shell disposed at the upper end of the first shell, an air guide groove opened on the inner side of the second shell, an installation bracket for auxiliary exhaust mounted on the upper end of the second shell, a first connecting plate fixedly connected to the outer sides of both the first shell and the second shell, a rotating platform rotatably connected to the inner side of the installation bracket, and an air guide plate for diverting hot gas mounted on the upper end of the rotating platform.

[0007] In a preferred embodiment, a fixed frame is installed at the upper end of the mounting frame, and an air guide frame is fixedly connected to the lower end of the fixed frame. The air guide frame is rotatably connected to the air guide plate. A thermostat body is installed at the upper end of the fixed frame, and a thermostat tube body is provided at the lower end of the thermostat body.

[0008] In a preferred embodiment, a stacked housing is provided between the first housing and the second housing, and a second connecting plate is fixed to the outside of the stacked housing.

[0009] In a preferred embodiment, connecting grooves are provided on both sides of the stacked housing, and connecting frames are fixedly connected to the front and rear ends of the stacked housing. The connecting grooves are slidably connected to the connecting frames, and mounting grooves are provided on the outer side of the connecting frames.

[0010] In a preferred embodiment, a rotating plate is rotatably connected to the inner side of the stacked housing, a limiting groove is formed on the inner side of the rotating plate, and a moving rod is slidably connected to the inner side of the limiting groove. The moving rod is slidably connected to the stacked housing.

[0011] In a preferred embodiment, a movable frame is rotatably connected to the inner side of the movable rod, the movable frame and the connecting frame are slidably connected through a mounting groove, a support frame is installed on the outer side of the mounting groove, and a support spring is installed between the support frame and the movable frame.

[0012] In a preferred embodiment, a support block is provided between the two movable frames, a movable block is installed on the outside of the support block, and a hydraulic push rod is provided on the outside of the support block. The hydraulic push rod is fixedly connected to the movable block and is used to drive the movable block to move along a predetermined path.

[0013] The beneficial effects of this utility model are as follows: This invention achieves heat exchange by installing a heat exchange structure in a first shell and a second shell. It utilizes a gas guide groove to guide the hot gas generated after combustion to concentrate and move it. The hot gas drives the gas guide plate to rotate the rotating table to divert the hot gas and assist in exhaust, thereby improving the overall exhaust effect and reducing the damage caused by the hot gas. At the same time, the gas guide frame is used to assist in diverting the hot gas, and the surface temperature of the gas guide frame is reduced by the thermostat body and the thermostat tube body, which helps to reduce the temperature of the flowing hot gas, thereby reducing the possibility of the hot gas causing damage to other structures.

[0014] This utility model connects two stacked shells by setting a connecting frame and a connecting groove, and connects the first shell and the second shell by a first connecting plate and a second connecting plate, which together form a combustion chamber. At the same time, a hydraulic push rod drives the moving block and the support block to move, thereby driving the moving frame to move. The support frame and the support spring support the moving frame to drive the moving rod to move, assisting the rotating plate to reset and thus driving the rotating plate to rotate to adjust the effect of hot air circulation.

Detailed Implementation

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Refer to the instruction manual appendix Figures 1 to 5 A combustion chamber shell includes a first shell 1, a second shell 2 at the upper end of the first shell 1, an air guide groove 3 on the inner side of the second shell 2, an auxiliary exhaust mounting bracket 4 at the upper end of the second shell 2, a first connecting plate 5 fixedly connected to the outer side of both the first shell 1 and the second shell 2, a rotating platform 6 rotatably connected to the inner side of the mounting bracket 4, and an air guide plate 7 for diverting hot gas installed at the upper end of the rotating platform 6.

[0023] It should be noted that the combustion chamber is formed by the first housing 1 and the second housing 2, and a combustion structure is set at the lower end of the first housing 1. The hot gas generated after combustion is guided to concentrate and move through the air guide groove 3. The hot gas drives the air guide plate 7 to drive the rotating table 6 to rotate, thereby diverting the hot gas and assisting in exhaust, improving the overall exhaust effect and reducing the damage of hot gas.

[0024] It is worth noting that there are multiple air guide plates 7, and gaps are provided between the air guide plates 7 to facilitate the discharge of hot air. At the same time, heat exchange structures can be provided on the outer side of the first shell 1 and the second shell 2 to facilitate normal operation, and exhaust pipes can be installed on the outer side of the mounting frame 4 to facilitate the discharge of exhaust gas.

[0025] Refer to the instruction manual appendix Figure 2 A fixed frame 8 is installed at the upper end of the mounting frame 4, and a guide frame 9 is fixedly connected to the lower end of the fixed frame 8. The guide frame 9 is rotatably connected to the guide plate 7. A thermostat body 10 is installed at the upper end of the fixed frame 8, and a thermostat tube body 11 is provided at the lower end of the thermostat body 10.

[0026] It should be noted that the hot air is diverted by the air guide frame 9, and the surface temperature of the air guide frame 9 is reduced by the thermostat body 10 and the thermostat tube body 11, which helps to reduce the temperature of the hot air flowing through it, thereby reducing the possibility of the hot air causing damage to other structures.

[0027] Refer to the instruction manual appendix Figures 4 to 5 A stacked housing 12 is provided between the first housing 1 and the second housing 2, and a second connecting plate 13 is fixedly connected to the outside of the stacked housing 12.

[0028] It should be noted that the first housing 1, the second housing 2, and the stacked housing 12 are connected by the first connecting plate 5 and the second connecting plate 13.

[0029] Refer to the instruction manual appendix Figures 4 to 5 Both sides of the stacked housing 12 are provided with connecting grooves 14, and the front and rear ends of the stacked housing 12 are fixedly connected with connecting frames 15. The connecting grooves 14 and the connecting frames 15 are slidably connected, and the outer side of the connecting frame 15 is provided with an installation groove 16.

[0030] It should be noted that the two stacked housings 12 are docked and fixed together by the connecting groove 14 and the connecting bracket 15.

[0031] Refer to the instruction manual appendix Figures 4 to 5 A rotating plate 17 is rotatably connected to the inner side of the stacked housing 12. A limiting groove 18 is formed on the inner side of the rotating plate 17. A moving rod 19 is slidably connected to the inner side of the limiting groove 18. The moving rod 19 is slidably connected to the stacked housing 12.

[0032] It should be noted that the rotating plate 17 is driven to rotate by the moving rod 19 in conjunction with the limiting groove 18, thereby guiding or blocking the movement of hot air through the rotating plate 17.

[0033] Refer to the instruction manual appendix Figures 4 to 5 The inner side of the movable rod 19 is rotatably connected to the movable frame 20. The movable frame 20 and the connecting frame 15 are slidably connected through the mounting groove 16. The outer side of the mounting groove 16 is equipped with a support frame 21. A support spring 22 is installed between the support frame 21 and the movable frame 20.

[0034] It should be noted that the movable frame 20 is supported by the support frame 21 and the support spring 22, and the movable frame 20 drives the movable rod 19 to move.

[0035] Refer to the instruction manual appendix Figures 4 to 5 A support block 23 is provided between the two movable frames 20. A movable block 24 is installed on the outside of the support block 23. A hydraulic push rod 25 is provided on the outside of the support block 23. The hydraulic push rod 25 is fixedly connected to the movable block 24. The hydraulic push rod 25 is used to drive the movable block 24 to move along a predetermined path.

[0036] It should be noted that the hydraulic push rod 25 drives the moving block 24 to move, which in turn drives the support block 23 to rise and fall to support the moving frame 20 to move, thereby driving the rotating plate 17 to rotate.

[0037] It is worth noting that the two stacked housings 12 are set as a group, and the connecting frame 15 and connecting groove 14 between the stacked housings 12 correspond one-to-one. At the same time, the hydraulic push rod 25 of the stacked housing 12 corresponds to the moving block 24 of the other stacked housing 12, and multiple hydraulic push rods 25 are controlled simultaneously by the PLC controller. The first connecting plate 5 and the second connecting plate 13 are both provided in multiple groups, which can be connected at intervals by bolts. While connecting the first housing 1, the second housing 2 and the stacked housing 12 group, the connection between the stacked housings 12 is kept stable. A telescopic rod is provided between the support frame 21 and the moving frame 20 to facilitate the normal movement of the moving frame 20.

[0038] Working principle: First, two stacked housings 12 are connected by connecting frame 15 and connecting groove 14, and the first housing 1 and the second housing 2 are connected by first connecting plate 5 and second connecting plate 13. Then, the first housing 1 and the second housing 2 form a combustion chamber, and a combustion structure is set at the lower end of the first housing 1. Then, the hydraulic push rod 25 drives the moving block 24 and the support block 23 to move, thereby driving the moving frame 20 to move, which in turn drives the rotating plate 17 to rotate to adjust the effect of hot air circulation. Finally, the moving frame 20 is supported by support frame 21 and support spring 22, and the moving frame 20 drives the moving rod 19 to move, assisting the rotating plate 17 to reset. In use, firstly, the hot gas generated after combustion is guided to concentrate and move through the air guide groove 3. Then, the hot gas drives the air guide plate 7 to rotate the rotating table 6, thereby diverting the hot gas and assisting in exhaust, improving the overall exhaust effect and reducing the damage caused by the hot gas. Next, the air guide frame 9 assists in diverting the hot gas, and the thermostat body 10 and the thermostat tube body 11 reduce the surface temperature of the air guide frame 9, thereby helping to reduce the temperature of the flowing hot gas and reducing the possibility of the hot gas causing damage to other structures. Finally, heat exchange structures can be set on the outside of the first shell 1 and the second shell 2 for heat exchange, facilitating normal operation.

[0039] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
