Description

Technical Field

[0001] The utility model relates to the technical field of muffle tubes, and more specifically to a hanging muffle tube used in a vertical bright annealing furnace. Background Art

[0002] Vertical bright annealing furnace is widely used in metal processing, metallurgy, electronic materials and other fields. As the core component of the annealing furnace, the performance of the muffle tube directly affects the effect of the annealing treatment. However, in the vertical bright annealing furnace, the replacement process of the muffle tube often requires shutdown. The operator needs to dismantle part of the furnace structure to remove the old muffle tube and replace it with a new one. Because the muffle tube is large in size, it is generally moved by large machinery. Because it is vertical, it needs to be moved to a height higher than the distance at one end of the top of the bright annealing furnace by hoisting. Then put it into the furnace and connect it with other equipment. The muffle tube works for a long time in a high temperature environment. High temperature creep refers to the slow plastic deformation of the material under high temperature and stress. Because the oxide film on the surface of the muffle tube may be destroyed and connected to the surface of the bright annealing furnace at the oxidized part, it may become very difficult to remove the muffle tube. Extra tools and time are required to separate them, which increases the complexity and labor intensity of the replacement process.

DETAILED DESCRIPTION

[0017] The utility model is further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are merely illustrative and not limiting of the protection scope of the utility model. Example

[0018] like Figure 1-Figure 2As shown: A suspended muffle tube for a vertical bright annealing furnace, comprising: The muffle tube body 1 is usually in a tubular shape and is the core part of the whole set of equipment. It is made of special high-temperature materials to ensure that it can remain stable in a high-temperature environment and is not affected by the external environment.

[0019] At one end of the muffle body 1, we can see that a connecting plate 2 is provided. The existence of the connecting plate 2 is mainly to make a stable connection with other components to ensure the integrity of the whole set of equipment.

[0020] The lower part of the connecting plate 2 is fixedly connected to the supporting mechanism 3. This supporting mechanism not only serves to connect the bright annealing furnace, but also provides a solid support for the muffle tube body. This allows the muffle tube to remain stable in a high-temperature working environment, ensuring that it will not deform or shift due to long-term operation.

[0021] A locking mechanism 4 is specially designed in the middle of the supporting mechanism 3. The existence of this locking mechanism is mainly for connecting external lifting equipment. When the muffle tube needs to be moved or repaired, the lifting equipment can be quickly and safely connected to the supporting mechanism through this locking mechanism to achieve easy lifting of the muffle tube.

[0022] In addition to the core components mentioned above, a connecting pipe 5 is provided on one side of the supporting mechanism 3. The main function of this connecting pipe is to realize the import and export of fluid or gas. A valve 6 is installed at one end of the connecting pipe. This valve 6 can control the flow of fluid or gas to ensure that the supply and cutoff of fluid can be done accurately during production or experiment.

[0023] The muffle tube body and its related components form a complete and efficient system. Each component has its specific function and role, which together ensure the stable operation of the muffle tube in high temperature environment.

[0024] It can be understood that the core component of the support mechanism 3 is the fixed base 301, which serves as a stable foundation for the entire support mechanism and bears the weight and external force of the muffle tube. The fixed base 301 is usually made of strong and durable materials to ensure stability and reliability under high temperature and stress.

[0025] A connection hole 302 is provided on one side of the fixed base 301. The existence of these connection holes 302 allows the support mechanism to be conveniently connected to other components, such as the connection plate 2 of the muffle tube, to achieve the fixation and suspension of the muffle tube. The design and position of the connection hole 302 are determined according to specific needs and application scenarios to ensure the firmness and stability of the connection.

[0026] Going deeper into the fixed base 301, we can see the existence of the connection chamber 303. The connection chamber 303 is a cavity structure inside the support mechanism, which is used to accommodate key components such as the connection ring. The design of the connection chamber 303 can protect these components from the external environment and provide additional support and stability.

[0027] A connection ring 304 is provided inside the connection chamber 303. The connection ring 304 is one of the key connection elements of the support mechanism, and it realizes the overall stability and fixity of the support mechanism by connecting with other components. The connection ring is usually made of high-strength material to withstand tensile and compressive forces and maintain the firmness of the connection.

[0028] The support mechanism 3 forms a stable and reliable support system through the organic combination of the fixed base, connection holes, connection chamber and connection ring. The existence of this support mechanism ensures the normal operation and long-term use of the muffle tube in a high temperature environment. At the same time, this structural design also reflects the ingenuity and meticulousness of engineering technology, providing a solid support guarantee for various industrial applications.

[0029] It can be understood that one end of the connecting ring 304 is fixedly connected to the connecting tube 5. This means that one end of the connecting tube 5 is directly inserted into or firmly connected to the connecting ring by other means, ensuring that the connection between the two will not loosen or shift. This connection method ensures the transmission stability and sealing of the fluid or gas between the connecting tube 5 and the supporting mechanism 3.

[0030] On the other side of the connecting ring 304, multiple groups of telescopic rods 305 are designed. These telescopic rods 305 are not fixed in length, but can be extended or contracted as needed. This design has a certain flexibility, so that the support mechanism can adapt to different working environments and stress conditions.

[0031] One end of each of these telescopic rods 305 is fixedly connected to a sliding plate 306. The sliding plate 306 is a planar structure that can slide in a specific track or groove. When the length of the telescopic rod changes, the sliding plate 306 will also move accordingly. This sliding design not only provides a stable support for the telescopic rod, but also allows fine adjustment within a certain range to meet actual work needs.

[0032] It can be understood that the locking mechanism 4 includes two main parts, a left connecting ring 401 and a right connecting ring 402. As a part of the locking mechanism, the left connecting ring 401 is located on one side of the supporting mechanism 3. The right connecting ring 402 is provided on the side corresponding to the left connecting ring 401. The existence of these two connecting rings provides a stable framework for the locking mechanism, ensuring that it can bear and transmit external forces.

[0033] In order to further enhance the stability of the connection, both ends of the left connecting ring 401 and the right connecting ring 402 are provided with connecting ears 403. The connecting ear 403 is a structure protruding from the surface of the connecting ring, usually in the form of a sheet. Its main function is to be rotatably connected with the connecting block so that the relative position between the connecting rings can be adjusted and fixed after adjustment.

[0034] The connection block 404 is a key component in the locking mechanism, and it is connected to the connection ear 403 by rotation. This means that the connection block can be rotated on the connection ear to meet different connection angle requirements. This rotation connection method greatly increases the flexibility of the locking mechanism, allowing it to adapt to more lifting scenarios.

[0035] A connecting rod 405 is provided inside the connecting block 404. The connecting rod 405 is a solid rod-shaped structure, one end of which is fixedly connected to the inside of the right connecting ring. When the connecting block and the connecting ear are adjusted to a certain relative position, the existence of the connecting rod ensures a stable connection between them, so that the entire locking mechanism forms a complete whole.

[0036] It is understandable that the right connecting ring 402 is an important component of the locking mechanism, and a connecting groove 406 is specially designed inside the right connecting ring. The connecting groove 406 is an empty groove opened inside the right connecting ring, and has a specific shape and size. Its existence provides a stable placement space for the connecting rod.

[0037] The connection groove 406 is not just a simple space, but also has a connection rod 405 fixedly connected therein. After one end of the connection rod is inserted into the connection groove, a stable connection is formed with the connection groove through a specific fixing method, such as welding, screw fixing, etc. This design ensures that the connection rod will not fall off from the connection groove, providing additional protection for the stability of the locking mechanism.

[0038] When it is necessary to connect with external equipment, the existence of the connecting rod provides a solid support for the right connecting ring. Because the other end of the connecting rod is fixedly connected to the inside of the right connecting ring, it can withstand and transmit external forces, ensuring that the locking mechanism can remain stable when subjected to external forces.

[0039] It is understood that a chain 407 is specially designed on one side of the connecting block 404. The chain 407 is made of a solid material, has multiple links, and can be flexibly bent and stretched. One end of the chain is fixedly connected to the connecting block to form a stable connection point.

[0040] The other end of the chain 407 is fixedly connected to one end of the connecting rod 405. In this way, the connecting rod 405 and the chain 407 form a continuous connection path, further enhancing the overall stability. At the same time, the flexibility of the chain allows the connecting rod to move freely within a certain range, preventing the connecting rod 405 from accidentally falling off and causing adverse consequences, thereby adapting to different connection requirements.

[0041] First, the presence of the chain provides additional connection insurance, ensuring that the connection between the connecting block and the connecting rod will not loosen or accidentally disconnect. Second, the chain can disperse and carry external stress, protecting the connecting block and the connecting rod from damage. Finally, the flexibility of the chain provides better adaptability for the entire locking mechanism, enabling it to maintain a stable connection effect in different working environments.

[0042] The working process of the utility model is as follows: first, the fixed base is placed in a suitable position to ensure that it is stable. On one side of the fixed base, find the connection hole and ensure that it is aligned with other parts. The connection chamber is located inside the fixed base, and the connection ring is installed inside the connection chamber. When installing the connection ring, ensure that it is stable and will not shake. One end of the connection ring is fixedly connected to the connection pipe to ensure that the connection is airtight. Install the telescopic rod to the other side of the connection ring, and ensure that one end of the telescopic rod is fixedly connected to the sliding plate. These telescopic rods can be adjusted as needed to ensure the appropriate distance between the muffle tube and the annealing furnace, place the left and right connection rings in suitable positions, and ensure that the connection ears at both ends of them are rotatably connected to the connection block. The connection rod should be placed inside the connection block and form a fixed connection with the inside of the right connection ring. During the installation process, ensure that the locking mechanism can be freely connected to the external lifting equipment. Finally, fix the chain on one side of the connection block and ensure that it forms a fixed connection with the connection rod. The addition of the chain enhances the safety of the entire structure and ensures that there will be no accidental fall-off or breakage when the muffle tube is working.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
