Description

Technical Field

[0001] This utility model relates to the field of annealing furnaces, and in particular to a furnace body rapid cooling device. Background Technology

[0002] In steel production, the annealing furnace is a crucial processing piece of equipment. Its main function is to eliminate internal stress in the steel and improve its microstructure by precisely controlling the heating and holding processes, thereby enhancing the material's toughness, ductility, and other mechanical properties, making it easier for subsequent processing and meeting usage requirements. However, after annealing, the furnace interior and walls remain at high temperatures. If not cooled promptly, this not only reduces the equipment's lifespan but may also pose a threat to the surrounding environment and the safety of operators due to high-temperature radiation and heat conduction.

[0003] Traditional rapid cooling methods for furnace bodies typically employ natural cooling or forced air cooling. Natural cooling is less efficient and difficult to adapt to the fast-paced demands of modern continuous production. While forced air cooling can accelerate the cooling process, uneven airflow distribution can lead to excessively rapid cooling in certain areas, generating significant thermal stress and consequently affecting the stability of the furnace structure. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of low efficiency in existing rapid furnace cooling equipment, and to propose a rapid furnace cooling device.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution: A rapid cooling device for a furnace body includes an annealing furnace body. Multiple concave heat exchange plates are movably spliced ​​on the outer wall of the annealing furnace body. Multiple heat dissipation fins are evenly distributed on the outer wall of the heat exchange plates. Guide plates are provided at the intersection of the vertical and horizontal directions of the heat dissipation fins. Air blowing components are symmetrically installed at the lower end of the heat exchange plates. The airflow generated by the air blowing components flows along the space between the heat dissipation fins. The guide plates guide the vertical airflow into horizontal airflow.

[0006] Preferably, the blowing assembly includes a fan and a blower head movably mounted on the outer wall at the lower end of the heat exchange plate. The fan is fixedly mounted on a support of the annealing furnace body. Two conveying pipes are fixedly provided on the fan, and the ends of the conveying pipes are fixedly connected to the blower head. The airflow from the blower head covers the entire heat dissipation fins.

[0007] Preferably, a fixing column is fixedly provided on the side of the support of the annealing furnace body, and an installation block is slidably inserted into the groove of the fixing column. The upper end of the installation block is fixedly connected to the lower end of the heat exchange plate, and a stop block is inserted into the groove end of the fixing column. The installation block is in contact with the inner wall of the groove of the fixing column.

[0008] Preferably, the mounting block has two L-shaped locking blocks symmetrically arranged on its side, and the fan is locked between the locking blocks and the heat exchange plate.

[0009] Preferably, the guide plate has multiple slots on its inner side, and the slots are fitted to the ends of the heat dissipation fins.

[0010] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the airflow generated by the blowing assembly is evenly distributed across the surface of the heat dissipation fins under the guidance of the guide plate, allowing heat to dissipate rapidly and preventing localized overheating or uneven cooling, thus effectively reducing the impact of thermal stress on the furnace body. Simultaneously, the modular heat exchange plate design facilitates installation and maintenance, and the heat dissipation area can be flexibly adjusted according to actual needs, improving energy utilization.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] Example: This example provides a rapid cooling device for the furnace body. See [link to example]. Figure 1-3 Specifically, the furnace body 1 is equipped with multiple concave heat exchange plates 11 that are movably spliced ​​on the outer wall of the furnace body 1. Multiple heat dissipation fins 12 are evenly distributed on the outer wall of the heat exchange plates 11. Guide plates 13 are provided at the intersection of the vertical and horizontal directions of the heat dissipation fins 12. Air blowing components 2 are symmetrically installed at the lower end of the heat exchange plates 11. The airflow generated by the air blowing components 2 flows along the heat dissipation fins 12. The guide plates 13 guide the vertical airflow into the horizontal airflow.

[0017] In this embodiment, the heat exchange plate 11 is made of aluminum alloy and is attached to the outer wall of the furnace body to increase the heat dissipation area and improve the heat exchange efficiency; the heat dissipation fins 12 increase the heat dissipation surface area and enhance air convection heat dissipation; the guide plate 13 changes the airflow direction, turning the airflow from vertical to horizontal, ensuring that the airflow evenly covers all the heat dissipation fins 12; the high-temperature furnace body heat is conducted to the heat exchange plate 11, the heat dissipation fins 12 increase the heat dissipation area, the airflow carries away the heat when flowing between the fins, and the guide plate 13 optimizes the airflow distribution to avoid local overheating.

[0018] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the air blowing assembly 2 includes a fan 21 and an air blowing head 23 movably installed on the outer wall of the lower end of the heat exchange plate 11. The fan 21 is fixedly installed on the bracket of the annealing furnace body 1. Two conveying pipes 22 are fixedly provided on the fan 21. The ends of the conveying pipes 22 are fixedly connected to the air blowing head 23. The airflow from the air blowing head 23 covers the entire heat dissipation fins 12.

[0019] In this embodiment, the fan 21 provides forced convection airflow to accelerate heat dissipation. The delivery pipe 22 connects the fan 21 and the blower head 23 to ensure stable airflow delivery. The blower head 23 guides the airflow into the gaps between the heat dissipation fins 12, covering the entire heat dissipation area. After the fan 21 starts, the airflow enters the blower head 23 through the delivery pipe 22. The blower head 23 evenly delivers the airflow into the gaps between the heat dissipation fins 12, and the guide plate 13 adjusts the airflow direction to make the airflow lateral, maximizing the heat dissipation efficiency.

[0020] In the specific implementation process, such as Figure 1 and Figure 2 As shown, a fixing column 3 is fixedly provided on the side of the support of the annealing furnace body 1. An installation block 31 is slidably inserted into the groove of the fixing column 3. The upper end of the installation block 31 is fixedly connected to the lower end of the heat exchange plate 11. A stop block 32 is inserted into the end of the groove of the fixing column 3. The installation block 31 fits against the inner wall of the groove of the fixing column 3. Two L-shaped locking blocks 4 are symmetrically provided on the side of the installation block 31. The fan 21 is locked between the locking block 4 and the heat exchange plate 11.

[0021] In this embodiment, the fixing column 3 provides an installation groove, facilitating the modular assembly and disassembly of the heat exchange plate 11. The mounting block 31 connects the heat exchange plate 11 to the fixing column 3, ensuring stable fixation. The stop block 32 prevents the mounting block 31 from slipping off, enhancing structural stability. The clamping block 4 assists in fixing the fan 21, preventing vibration displacement. The mounting block 31 slides along the groove of the fixing column 3 to adjust its position. After the stop block 32 is locked to the end of the fixing column 3 with bolts, the heat exchange plate 11 is firmly fixed. The clamping block 4 cooperates with the heat exchange plate 11 to clamp the fan 21, ensuring the overall structural stability.

[0022] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the guide plate 13 has multiple slots 5 on its inner side, which fit against the ends of the heat dissipation fins 12. The slots 5 precisely position the heat dissipation fins 12, ensuring a tight fit between the guide plate 13 and the heat dissipation fins 12. The guide plate 13 is made of a flexible metal material. After the slots 5 are connected to the heat dissipation fins 12, the friction is greater than the airflow from the blower head 23. After the airflow moves vertically from the heat dissipation fins 12 and contacts the inner arc surface of the guide plate 13, the airflow moves along the arc surface along the horizontal heat dissipation fins 12. Since the heat exchange plate 11 has blower components 2 on both sides, the airflow on both sides finally contacts the middle of the horizontal heat dissipation fins 12, and the airflow leaves the heat dissipation fins 12 after the collision.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
