Description

Technical Field

[0001] This invention relates to the technical field of blast furnace installation, and in particular to a cooling wall fixing structure and a blast furnace. Background Technology

[0002] Cooling walls are a common type of cooler used in blast furnaces. Installed between the brick lining and the furnace shell, they facilitate the efficient removal of heat from the furnace through surface cooling, preventing high-temperature heat from directly reaching the furnace shell. Therefore, cooling walls must withstand not only high temperatures but also wear from the furnace charge, erosion from molten slag, and scouring from the gas flow, resulting in an extremely harsh working environment.

[0003] In existing cooling wall installation processes, such as Chinese Patent No. CN218910406U, a cooling wall installation tool is disclosed, including a hanging plate, a sliding cylinder fixedly connected to the hanging plate, a sliding rod rotatably connected inside the sliding cylinder, a rotating mechanism installed on the sliding rod, a support box fixedly connected to the sliding rod, two push rods slidably connected inside the support box, each push rod is equipped with a pusher, the pusher includes a movable toothed belt, the movable toothed belt is fixedly connected to the push rod, a first motor is installed on the support box, a power gear is fixedly connected to the output end of the first motor, the power gear meshes with the movable toothed belt, and a support mechanism is installed on one of the push rods near the left end.

[0004] In the aforementioned prior art, a cooling wall pusher is mainly used to replace manual labor in holding the cooling wall, making the installation between the cooling wall and the furnace shell more secure. However, the aforementioned prior art does not take into account the need to maintain a uniform gap between the cooling wall and the furnace shell for subsequent filling and sealing. After using the pusher to push the cooling wall onto the furnace shell, it is not easy to adjust the gap between the cooling wall and the furnace shell. If there is a difference in the gap between the cooling wall and the furnace shell, it will affect the final cooling effect. On the other hand, the cooling wall is not easy to replace, on average it is about six to eight years. After years of corrosion, the fixing bolts and nuts of the cooling wall are usually rusted together, making it very difficult to loosen. They need to be cut off with a cutting machine, which is very inconvenient.

[0005] Therefore, there is still room for improvement in the aforementioned existing technologies. Summary of the Invention

[0006] To improve the safety of the cooling wall during installation, its stability after installation, and the convenience of disassembly, this application provides a cooling wall fixing structure and a blast furnace.

[0007] The cooling wall fixing structure provided in this application adopts the following technical solution: A cooling wall fixing structure includes a cooling pipe, a cooling wall, a first fixing module, a second fixing module, and an interlocking module. The cooling pipe is installed on the cooling wall. The first fixing module and the second fixing module work together to fix the cooling wall. The first fixing module, which has a safety protection function, and the second fixing module, which has a quick-release function, work together to fix the cooling wall. The interlocking module locks adjacent cooling walls together, thereby enhancing the stability of the cooling wall during use.

[0008] Preferably, the first fixing module includes a connecting rod, a connecting mechanism, and a blocking mechanism. The connecting rod consists of an end connecting rod and a tail connecting rod. The right end of the end connecting rod has a square blind hole groove, and the left end of the tail connecting rod is in sliding fit with the blind hole groove. The square blind hole groove prevents relative rotation between the tail connecting rod and the end connecting rod. The outer periphery of the tail connecting rod is threaded. The cooling wall has an installation hole for the connecting rod, and the furnace shell has a through hole corresponding to the position of the installation hole. The connecting mechanism is disposed in the end connecting rod and connects and locks the end connecting rod and the tail connecting rod. The blocking mechanism is disposed on the outer periphery of the tail connecting rod.

[0009] Preferably, the connecting mechanism includes a snap-fit ​​block, an interceptor plate, and a mating groove. The snap-fit ​​block is slidably disposed inside the blind hole groove. A spring is connected between the snap-fit ​​block and the blind hole groove. The spring always pushes the snap-fit ​​block outward. A snap-fit ​​groove corresponding to the position of the snap-fit ​​block is opened on the outer periphery of the tail connecting rod. The interceptor plate is slidably disposed inside the end connecting rod. The bottom surface of the interceptor plate is in contact with the outer end surface of the snap-fit ​​block and limits the position of the snap-fit ​​block. In the initial state, the left end of the tail connecting rod is inserted into the blind hole groove. At this time, the snap-fit ​​block is inserted into the snap-fit ​​groove, thereby locking and limiting the position of the tail connecting rod. The spring is in a compressed state. The interceptor plate is located at the outer end of the snap-fit ​​block, thereby limiting the position of the snap-fit ​​block and preventing the snap-fit ​​block from moving outward under the action of the spring and thus causing it to fall out of the snap-fit ​​groove. A mating groove is opened on the right end of the interceptor plate.

[0010] Preferably, the blocking mechanism includes a blocking plate, a telescopic member, a pressing groove, and a pressing member. The blocking plate is rotatably disposed on the outer periphery of the tail connecting rod via a rotating shaft. A second spring is connected between the blocking plate and the rotating shaft, which serves to reset and maintain the position of the blocking plate. In the initial state, the blocking plate remains perpendicular to the tail connecting rod under the action of the second spring. The telescopic member is slidably disposed in a sliding groove opened inside the blocking plate along its length direction. A third spring is connected between the telescopic member and the sliding groove, which serves to reset. The bottom end of the telescopic member is temporarily engaged with the mating groove. When the blocking plate is compressed and rotates to be parallel to the length direction of the tail connecting rod, the bottom end of the telescopic member is inserted into the mating groove to form a temporary engagement. The top end of the telescopic member is provided with a chamfered structure, and a pressing groove is opened in the middle of the telescopic member. The pressing member is installed in the sliding groove, and the positions of the pressing member and the pressing groove correspond.

[0011] Preferably, the second fixing module includes a fixing seat, a threaded component, a top support plate, and a locking component. The fixing seat is fitted onto the outer periphery of the connecting rod for use. The outer periphery of the right end of the fixing seat is hexagonal, which facilitates tightening with tools. The inner surface of the fixing seat has an insertion groove corresponding to the position of the telescopic component. The threaded component is symmetrically slidably disposed inside the fixing seat. The inner surface of the arc-shaped threaded component has threads that mate with the tail connecting rod. The top support plate is slidably disposed inside the fixing seat. The top support plate is located between the threaded component and the fixing seat and fixes the position of the threaded component. When the top support plate is located between the threaded component and the fixing seat, the threaded component cannot slide. At this time, the distance between the threaded components is minimal but they do not contact each other, avoiding the situation where the threaded components contact each other and rust together. The locking component is rotatably disposed in the top support plate.

[0012] Preferably, the locking member has a protrusion in the middle, and the fixing seat has a locking groove corresponding to the position of the protrusion. The protrusion is initially located in the locking groove, thereby locking the movement of the locking member in the front-back direction.

[0013] Preferably, the interlocking module includes interlocking component one, interlocking component two, interlocking groove, hanging groove, and interlocking plate. The interlocking components are fitted onto the outer periphery of the connecting rod. Interlocking component one has an internal cavity, in which the interlocking groove slides. The hollow interlocking groove has an inlet at one end near the interlocking plate, through which the interlocking plate slides into the interlocking groove. The upper end of the interlocking groove has a release outlet. When it is necessary to unlock the interlocking groove and interlocking plate, the interlocking plate slides vertically to release from the release outlet. The interlocking groove has anti-backlash teeth slidingly installed inside, connected to the anti-backlash teeth by a spring four, which serves a reset function. The bottom of the interlocking slot has a hook groove with an L-shaped cross-section. The hook groove consists of a vertical groove and a horizontal groove. In the initial state, the hook is engaged with the vertical groove. A spring five connects the interlocking slot to the empty cavity. The spring five always tends to push the interlocking slot outward. The structure of the second interlocking component is the same as that of the first interlocking component. The second interlocking component has a sliding interlocking plate inside. The surface of the interlocking plate has an anti-tipping groove that engages with the anti-tipping teeth. The bottom of the interlocking plate has a locking groove with the same structure as the hook groove. A spring six connects the interlocking plate to the second interlocking component. The spring six always tends to push the interlocking plate outward. The interlocking plate and the interlocking slot are in an insert-type sliding fit.

[0014] Preferably, the first interlocking component includes a pad, a positioning pin, a pressing component, and a hook component. The pad is sleeved on the outer periphery of the connecting rod. Positioning pins are evenly distributed on the bottom surface of the pad. Positioning holes corresponding to the positions of the positioning pins are provided on the cooling wall. The positioning pins are inserted into the positioning holes to position the pad. The pressing component is slidably disposed on the right side surface of the pad. The hook component is slidably disposed on the side wall of the blank cavity. A spring is connected between the hook component and the blank cavity. The spring serves to reset. The hook component and the hanging groove are temporarily engaged.

[0015] Preferably, a blast furnace has a cooling wall fixing structure provided on its furnace shell.

[0016] In summary, the beneficial technical effects of this application are as follows: The present invention discloses a cooling wall fixing structure and a blast furnace, which interlocks the cooling walls with adjacent cooling walls to form an interconnected whole, thereby enhancing the stability of the cooling walls after installation. When a cooling wall becomes loose and tends to fall off, this tendency is distributed across the overall interlocking structure to prevent it from falling off. The position of the cooling walls is also defined, ensuring that the gap between the cooling walls and the furnace shell remains uniform. Furthermore, temporary clamping protection is provided during the installation of the cooling walls to lock their position and prevent them from falling off when manpower is insufficient or insufficient support is provided. In addition, this application provides a non-cutting, easily disassembled structure to address the issue of corrosion, increasing convenience. Attached Figure Description

[0019] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0020] This application discloses a cooling wall fixing structure. By installing and protecting the cooling wall 2 and using multiple interlocking mechanisms to prevent the cooling wall 2 from falling off during and after installation, the safety is improved. The structure is also designed to be easy to disassemble to prevent severe corrosion from making disassembly impossible.

[0021] Reference Figure 1 , Figure 2 As shown, a cooling wall fixing structure includes a cooling pipe 1, a cooling wall 2, a first fixing module 3, a second fixing module 4, and an interlocking module 5. The cooling pipe 1 is installed on the cooling wall 2. The first fixing module 3 and the second fixing module 4 work together to fix the cooling wall 2, with the first fixing module 3 having a safety protection function and the second fixing module 4 having a quick release function. The interlocking module 5 locks adjacent cooling walls 2 together, thereby enhancing the stability of the cooling wall 2 in use.

[0022] During actual installation, the first fixing module 3 is inserted into the mounting hole on the cooling wall 2. Then, the interlocking module 5 is fitted onto the first fixing module 3 from the other end. After ensuring the first fixing module 3 is aligned with the through hole on the furnace shell, the cooling wall 2 is pushed towards the inner wall of the furnace shell. The first fixing module 3 passes through the through hole and provides a safety anti-drop protection for the cooling wall 2. The cooling wall 2 abuts against the inner wall of the furnace shell, triggering the interlocking module 5, locking adjacent cooling walls 2 together. Next, the second fixing module 4 is fitted onto the first fixing module 3 from the outside of the furnace shell and tightened using threads. During tightening, the second fixing module 4 disables the safety anti-drop protection of the first fixing module 3. When disassembly is required later, the second fixing module 4 is unscrewed from the first fixing module 3 (if the corrosion is severe, the second fixing module 4 is manually triggered). The easy-to-detach structure of module 4 triggers the splitting of the first fixing module 3 when the second fixing module 4 is disassembled, thus facilitating the disassembly work. After the first fixing module 3 and the second fixing module 4 are removed, the cooling wall 2 can be removed, and then the interlocking module 5 can be removed. Due to the long service time and harsh working environment, the cooling wall 2, the first fixing module 3, the second fixing module 4, and the interlocking module 5 can be replaced or repaired according to the specific situation (rust, deformation, damage, etc.). This application interlocks the individual cooling wall 2 as a whole, which enhances the stability of the cooling wall 2 after installation and prevents it from falling off. It also restricts the position of the cooling wall 2, ensuring that the spacing between the cooling walls 2 is the same, making the arrangement of the cooling walls 2 more uniform and the position more precise. In addition, a disassembly structure that does not require cutting is set for easy disassembly in case of easy rust, which increases convenience.

[0023] Reference Figure 6 As shown, this application includes a first fixing module 3 that connects the furnace shell and the cooling wall 2. The first fixing module 3 includes a connecting rod, a connecting mechanism 33, and a blocking mechanism 34. The connecting rod consists of an end connecting rod 31 and a tail connecting rod 32. The right end of the end connecting rod 31 has a square blind hole groove 311. The left end of the tail connecting rod 32 is in sliding fit with the blind hole groove. The square blind hole groove 311 prevents relative rotation between the tail connecting rod 32 and the end connecting rod 31. The outer periphery of the tail connecting rod 32 is threaded. The cooling wall 2 has an installation hole for the connecting rod. The furnace shell has a through hole corresponding to the position of the installation hole. The connecting mechanism 33 is disposed in the end connecting rod 31 and connects and locks the end connecting rod 31 and the tail connecting rod 32. The blocking mechanism 34 is disposed on the outer periphery of the tail connecting rod 32.

[0024] Reference Figure 6 , Figure 7 As shown, the connecting mechanism 33 includes a snap-fit ​​block 331, an interceptor plate 332, and a mating groove 333. The snap-fit ​​block 331 is slidably disposed inside the blind hole groove 311. A spring is connected between the snap-fit ​​block 331 and the blind hole groove 311. The spring always maintains a tendency to push the snap-fit ​​block 331 outward. A snap-fit ​​groove corresponding to the position of the snap-fit ​​block 331 is opened on the outer periphery of the tail connecting rod 32. The interceptor plate 332 is slidably disposed inside the end connecting rod 31. The bottom surface of the interceptor plate 332 is adjacent to the outer end surface of the snap-fit ​​block 331. The two parts are in contact and fit together, and limit the position of the locking block 331. In the initial state, the left end of the tail connecting rod 32 is inserted into the blind hole groove. At this time, the locking block 331 is inserted into the locking groove, thereby locking and limiting the position of the tail connecting rod 32. The spring is in a compressed state, and the intercepting plate 332 is located at the outer end of the locking block 331, thereby limiting the position of the locking block 331 and preventing the locking block 331 from moving outward under the action of the spring, thus causing it to fall out of the locking groove. The right end of the intercepting plate 332 is provided with a mating groove 333.

[0025] In actual use, the connecting rod is inserted into the mounting hole on the cooling wall 2, and then the connecting rod is aligned with the through hole on the furnace shell and inserted into the through hole to connect the cooling wall 2 and the furnace shell. At this time, the blocking mechanism 34 temporarily latches the connecting rod and the furnace shell, thereby playing a temporary safety and anti-falling role. When disassembling later, the second fixing module 4 triggers the blocking mechanism 34, causing the intercepting plate 332 to be pulled to the right. The intercepting plate 332 no longer blocks the latching block 331. Under the action of the spring, the latching block 331 is dislodged from the latching groove, and the end connecting rod 31 and the tail connecting rod 32 can slide and separate left and right. The blocking mechanism 34 can be directly removed from the outside of the cooling wall 2 along with the tail connecting rod 32.

[0026] Reference Figure 7 As shown, after the cooling wall 2 is attached to the inner wall of the furnace shell, there is a risk of it falling off if the second fixing module 4 is not used for fixation. Therefore, this application provides a blocking mechanism 34, which includes a blocking plate 341, a telescopic member 342, an extrusion groove 343, and an extrusion member 344. The blocking plate 341 is rotatably mounted on the outer periphery of the tail connecting rod 32 via a rotating shaft. A second spring connects the blocking plate 341 to the rotating shaft, and the second spring serves to reset and maintain the position of the blocking plate 341. In its initial state, the blocking plate 341 remains perpendicular to the tail connecting rod 32 under the action of the second spring. The telescopic member 342... 42 is slidably disposed in a sliding groove inside the baffle plate 341 along the length direction. A spring 3 is connected between the telescopic member 342 and the sliding groove, and the spring 3 plays a reset role. The bottom end of the telescopic member 342 is temporarily engaged with the mating groove 333. When the baffle plate 341 is squeezed and rotates to be parallel to the length direction of the tail connecting rod 32, the bottom end of the telescopic member 342 is inserted into the mating groove 333 to form a temporary engagement. The top end of the telescopic member 342 is provided with a chamfered structure. An extrusion groove 343 is provided in the middle of the telescopic member 342. An extrusion member 344 is installed in the sliding groove, and the positions of the extrusion member 344 and the extrusion groove 343 are corresponding.

[0027] During actual safety protection, the connecting rod is inserted into the through hole on the furnace shell. The baffle plate 341 gradually contacts and is squeezed against the inner wall of the furnace shell around the through hole. After being squeezed, the baffle plate 341 rotates until it is parallel to the length direction of the tail connecting rod 32, thus smoothly entering the through hole. When the baffle plate 341 is completely detached from the through hole, under the action of the second spring, the baffle plate 341 returns to a state perpendicular to the tail connecting rod 32. When the cooling wall 2 has a tendency to fall off, the baffle plate 341 is engaged with the through hole to suppress the tendency of the cooling wall 2 to fall off, providing rescue space for personnel and ensuring personnel safety. Afterwards, the second fixing module 4 is tightened on the tail connecting rod 32. The second fixing module 4 contacts and squeezes the baffle plate 341, and the baffle plate 341 is squeezed to the length direction of the tail connecting rod 32. The two parts are parallel in the direction of the angle, so as not to block the installation of the second fixing module 4 on the tail connecting rod 32. The fixing seat 41 gradually squeezes the top of the telescopic member 342, so that the telescopic member 342 is compressed. When the fixing seat 41 moves to the insertion slot and corresponds to the top of the telescopic member 342, the telescopic member 342 extends and resets and inserts into the insertion slot, thereby engaging with the fixing seat 41. When the fixing seat 41 moves to the right and disengages, the fixing seat 41 drives the telescopic member 342 to move to the right synchronously. The telescopic member 342 drives the intercepting plate 332 to move to the right. When the telescopic member 342 moves to the right and squeezes between the squeezing groove 343 and the squeezing member 344, the telescopic member 342 is compressed under the squeezing action of the squeezing member 344 and disengages from the insertion slot, so that the telescopic member 342 separates from the fixing seat 41 and does not hinder the disassembly of the fixing seat 41.

[0028] Reference Figure 8 As shown, this application includes a second fixing module 4 that cooperates with the first fixing module 3 to securely install the furnace shell and cooling wall 2. The second fixing module 4 includes a fixing seat 41, a threaded component 42, a top support plate 43, and a locking component 44. The fixing seat 41 is fitted onto the outer periphery of the connecting rod for use. The outer periphery of the right end of the fixing seat 41 is hexagonal, which facilitates tightening with tools. The inner surface of the fixing seat 41 has an insertion groove corresponding to the position of the telescopic component 342. The threaded component 42 is symmetrically slidably disposed within the fixing seat 41. The inner surface of the arc-shaped threaded part 42 is provided with threads that mate with the tail connecting rod 32. The top support plate 43 is slidably disposed inside the fixed seat 41. The top support plate 43 is located between the threaded part 42 and the fixed seat 41 and fixes the position of the threaded part 42. When the top support plate 43 is located between the threaded part 42 and the fixed seat 41, the threaded part 42 cannot slide. At this time, the distance between the threaded parts 42 is the smallest but they do not contact each other, which avoids the situation where the threaded parts 42 come into contact and rust together. The locking part 44 is rotatably disposed in the top support plate 43.

[0029] Reference Figure 8 As shown, the locking member 44 has a protrusion 441 in the middle, and the fixing base 41 has a locking groove corresponding to the position of the protrusion 441. In the initial state, the protrusion 441 is located in the locking groove, thereby locking the movement of the locking member 44 in the front-back direction.

[0030] During the actual fastening process, the fixing seat 41 is fitted onto the outer periphery, and the threaded part 42 is tightened with a tool using the thread action to complete the fastening installation. When disassembling later, if the corrosion is severe, the locking part 44 is rotated to disengage the protrusion 441 from the locking groove. Then, the top support plate 43 is pulled out to the right to unlock the position of the threaded part 42. At this time, a slight tap can be used to separate the threaded part 42 from the tail connecting rod 32.

[0031] Reference Figure 3 , Figure 4 As shown, this application includes an interlocking module 5 for interlocking the cooling walls 2. The interlocking module 5 includes an interlocking component 01R, an interlocking component 2, an interlocking slot 51, a hanging slot 512, and an interlocking plate 52. The interlocking component 01R is sleeved on the outer periphery of the connecting rod. A blank cavity is opened inside the interlocking component 01R, and the interlocking slot 51 is slidably arranged in the blank cavity. An inlet is opened at the end of the hollow interlocking slot 51 near the interlocking plate 52. The interlocking plate 52 slides into the interior of the interlocking slot 51 through the inlet. An outlet is opened at the upper end of the interlocking slot 51. When it is necessary to unlock the interlocking slot 51 and the interlocking plate 52, the interlocking plate 52 slides in the vertical direction to disengage from the outlet. An anti-backlash tooth 511 is slidably arranged inside the interlocking slot 51, and a spring is connected between the anti-backlash tooth 511 and the interlocking slot 51. Spring 4 serves as a reset mechanism. A hook groove 512 is provided at the bottom of the interlocking slot 51. The hook groove 512 has an L-shaped cross-section and consists of a vertical groove and a horizontal groove. The hook 56 is initially engaged with the vertical groove. Spring 55 connects the interlocking slot 51 to the empty cavity, and always tends to push the interlocking slot 51 outwards. The structure of interlocking part 2 is the same as that of interlocking part 1 (01R). A interlocking plate 52 is slidably fitted inside interlocking part 2. An anti-tipping groove 521 that engages with the anti-tipping tooth 511 is provided on the surface of interlocking plate 52. A locking groove with the same structure as the hook groove 512 is provided at the bottom of interlocking plate 52. Spring 6 connects interlocking plate 52 to interlocking part 2, and always tends to push interlocking plate 52 outwards. Interlocking plate 52 and interlocking slot 51 are in an insert-type sliding fit.

[0032] Reference Figure 3 , Figure 5As shown, the interlocking component 01R includes a pad 53, a positioning pin 54, a pressing component 55, and a hook component 56. The pad 53 is sleeved on the outer periphery of the connecting rod. The bottom surface of the pad 53 is evenly provided with positioning pins 54. The cooling wall 2 is provided with positioning holes corresponding to the positions of the positioning pins 54. The positioning pins 54 are inserted into the positioning holes to position the pad 53. The pressing component 55 is slidably disposed on the right side surface of the pad 53. The hook component 56 is slidably disposed on the side wall of the blank cavity. A spring 7 is connected between the hook component 56 and the blank cavity. The spring 7 plays a reset role. The hook component 56 and the hanging groove 512 are temporarily engaged.

[0033] During the actual interlocking process, the positioning pin 54 is aligned with the positioning hole and inserted, so that the pad 53 is located between the cooling wall 2 and the furnace shell. When the cooling wall 2 and the furnace shell are close together, the pressing member 55 gradually contacts the furnace shell and is squeezed into the pad 53. The pressing member 55 presses the hook member 56, causing it to slide. The hook member 56 disengages from the hanging groove 512, thereby unlocking the position of the interlocking slot member 51. Under the action of the spring, the interlocking slot member 51 is pushed out. Correspondingly, when the adjacent cooling wall 2 is installed, the interlocking plate member 52 is pushed out and inserted into the interlocking slot member 51. When the interlocking plate 52 presses against the anti-reverse tooth 511, it compresses the interlocking plate 52 and allows it to be inserted smoothly. When the anti-reverse groove 521 and the anti-reverse tooth 511 are aligned, the anti-reverse tooth 511 is reset and inserted into the anti-reverse groove 521 under the action of the spring 4, so that the interlocking plate 52 cannot retract (at this time, the interlocking plate 52 can continue to move forward, and the anti-reverse groove 521 will press against the anti-reverse tooth 511 when it moves forward, causing the anti-reverse tooth 511 to contract). When disassembling, after the second fixing module 4, the first fixing module 3 and the cooling wall 2 are disassembled at one time, the interlocking plate 52 and the interlocking groove 51 can be separated and disassembled by sliding up and down.

[0034] Reference Figure 1 As shown, a blast furnace is provided with a cooling wall fixing structure on the furnace shell.

[0035] The implementation principle of this embodiment is as follows: Step 1: Installation: A. Insert the connecting rod into the mounting hole on the cooling wall 2; B. Insert the positioning pin 54 into the positioning hole to install the pad 53; C. After aligning the connecting rod with the through hole on the furnace shell, push the cooling wall 2 toward the inner wall of the furnace shell. The connecting rod passes through the through hole and the baffle plate 341 engages with the through hole to protect the position of the cooling wall 2 from falling. At the same time, when the cooling wall 2 is in contact with the inner wall of the furnace shell, the interlocking module 5 is triggered and the interlocking slot 51 is pushed out. D. Repeat step C above. At this time, the interlocking module 5 is triggered, causing the interlocking plate 52 to be pushed out. The interlocking slot 51 and the interlocking plate 52 are engaged, so that the two adjacent cooling walls 2 are locked together. E. After the position of the cooling wall 2 is determined, put the fixing seat 41 on the connecting rod and tighten it. Step Two: Disassembly A. Rotate the locking part 44 to unlock the top support plate 43 and pull it to the right, so that the position of the threaded part 42 is unlocked. At this time, a slight tap can be used to separate the threaded part 42 from the tail connecting rod 32, and the end connecting rod 31 and the tail connecting rod 32 are unlocked. B. Remove the second fixing module 4, the first fixing module 3, the cooling wall 2, and the interlocking module 5 in sequence, and replace or repair them according to the actual situation.

[0036] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
