Description

Technical Field

[0001] This application relates to the field of heat exchanger technology, specifically a detachable plate heat exchanger for waste heat recovery from desulfurization slurry. Background Technology

[0002] Detachable plate heat exchangers are high-efficiency heat exchange devices, mainly composed of heat transfer plates, gaskets, clamping devices (such as clamps and bolts), and inlet / outlet pipes. Their core feature is the flexible disassembly of the plates, facilitating cleaning, maintenance, and replacement. They are suitable for scenarios requiring frequent maintenance or handling media prone to scaling. In practical applications, to ensure normal operation and extend service life, heat exchangers must be disassembled and thoroughly inspected periodically. However, existing disassembly methods are cumbersome, requiring the removal of multiple fixing bolts one by one. This step is time-consuming and physically demanding. After all bolts are removed, the internal components of the heat exchanger must be opened individually for further detailed inspection and maintenance. Because bolt removal must be done sequentially, rapid and efficient disassembly is not possible, which affects the overall progress of maintenance work and hinders the effective improvement of heat exchanger maintenance efficiency.

[0003] Therefore, it is necessary to provide a detachable plate heat exchanger for waste heat recovery of desulfurization slurry to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a detachable plate heat exchanger for waste heat recovery of desulfurization slurry, which solves the problem that current heat exchangers need to be disassembled and inspected regularly during use. However, the current disassembly method requires removing multiple bolts and opening the internal components for subsequent maintenance. Removing the bolts one by one is time-consuming and laborious, and cannot be done quickly for disassembly and maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detachable plate heat exchanger for waste heat recovery of desulfurization slurry, comprising a detachable plate heat exchanger, a fixing plate provided on the right side of the detachable plate heat exchanger, a support rod fixedly connected to the right side of the detachable plate heat exchanger, the right side of the support rod extending through to the right side of the fixing plate, a limit frame fixedly connected to the top and bottom of the right side of the fixing plate, a clamping assembly provided inside the limit frame, and a transmission assembly provided inside the fixing plate; The clamping assembly is used to secure the support rod; The transmission component is used to drive the clamping component.

[0006] Preferably, the clamping assembly includes a bidirectional screw, which is rotatably connected to the inner side of the limiting frame. A threaded sleeve is threaded onto the surface of the bidirectional screw, and a clamping plate is fixedly connected to the side wall of the threaded sleeve. A groove for engaging with the clamping plate is provided on the inner side of the support rod.

[0007] Preferably, the transmission assembly includes a first helical gear, which is fixedly connected to the surface of a bidirectional screw, a second helical gear meshing with the outer side of the first helical gear, and a metal rod fixedly connected to the side wall of the second helical gear.

[0008] Preferably, a slide plate is fixedly connected to the inner side of the card plate, and a slide rail that engages with the slide plate is fixedly connected to the side wall of the fixed plate.

[0009] Preferably, a slip ring is fixedly connected to the outer side of the card plate, and a sliding rod is fixedly connected to the outer side of the limiting frame, with the slip ring and the sliding rod being slidably connected.

[0010] Preferably, a stabilizing ring is fixedly connected to the side wall of the fixing plate, and the stabilizing ring is rotatably connected to the metal rod.

[0011] Preferably, the number of support rods is several, and the support rods are arranged in a rectangular pattern.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention allows for the removal of the fixing plate to disassemble the detachable plate heat exchanger. When disassembling the detachable plate heat exchanger, the user rotates a metal rod, which in turn rotates a second helical gear. This second helical gear, in turn, rotates a double-ended screw, causing a threaded sleeve to move inwards. Simultaneously, the threaded sleeve moves the retaining plate inwards, disengaging it from its locking groove. The fixing plate can then be completely detached from the support rod, allowing the detachable plate heat exchanger to be removed for cleaning and maintenance. This facilitates quick and efficient disassembly. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 A detachable plate heat exchanger for waste heat recovery of desulfurization slurry includes a detachable plate heat exchanger 1, a fixing plate 2 is provided on the right side of the detachable plate heat exchanger 1, a support rod 3 is fixedly connected to the right side of the detachable plate heat exchanger 1, the right side of the support rod 3 extends through to the right side of the fixing plate 2, a limit frame 4 is fixedly connected to the top and bottom of the right side of the fixing plate 2, a clamping assembly 5 is provided inside the limit frame 4, and a transmission assembly 6 is provided on the inner side of the fixing plate 2. The clamping assembly 5 is used to fix the support rod 3; The transmission assembly 6 is used to drive the clamping assembly 5.

[0017] Please see Figure 4 The clamping assembly 5 includes a bidirectional screw 51, which is rotatably connected to the inner side of the limiting frame 4. A screw sleeve 52 is threadedly connected to the surface of the bidirectional screw 51, and a clamping plate 53 is fixedly connected to the side wall of the screw sleeve 52. A groove 54 is provided on the inner side of the support rod 3 to engage with the clamping plate 53.

[0018] Furthermore, the clamping component 5 effectively and firmly fixes the clamping plate 53, thereby ensuring that the clamping plate 53 maintains high stability during use and avoiding unstable shaking of the clamping plate 53. This greatly improves the user's ease of operation and user experience. The optimized design of the clamping component 5 makes the clamping plate 53 less susceptible to external interference after it is fixed, ensuring the stable operation of the equipment.

[0019] Please see Figure 4 The transmission assembly 6 includes a first helical gear 61, which is fixedly connected to the surface of the bidirectional screw 51. A second helical gear 62 meshes with the outer side of the first helical gear 61, and a metal rod 63 is fixedly connected to the side wall of the second helical gear 62.

[0020] Furthermore, the efficient transmission component 6 enables precise and smooth rotation of the bidirectional screw 51, significantly improving transmission efficiency and effectively reducing potential wobbling issues during rotation. This ensures the stability and reliability of the transmission process, providing users with a smooth operating experience. The precise design of the transmission component 6 ensures that the bidirectional screw 51 remains stable during rotation and is not easily affected by external factors.

[0021] Please see Figure 4 The inner side of the card plate 53 is fixedly connected to the slide plate 7, and the side wall of the fixed plate 2 is fixedly connected to the slide rail 8 that engages with the slide plate 7.

[0022] Furthermore, the design of the skateboard 7 enables efficient and smooth sliding with the slide rail 8, significantly improving sliding efficiency. At the same time, it ensures the stability of the card plate 53 during the sliding process, avoiding the inconvenience caused by the wobbling of the card plate 53, greatly facilitating the user's operation. The perfect fit between the skateboard 7 and the slide rail 8 makes the sliding process smooth and stable, enhancing the overall user experience.

[0023] Please see Figure 4 A slip ring 9 is fixedly connected to the outer side of the card plate 53, and a slide rod 10 is fixedly connected to the outer side of the limit frame 4. The slip ring 9 and the slide rod 10 are slidably connected.

[0024] Furthermore, the slip ring 9 enables smooth sliding between itself and the slide bar 10, ensuring the safety of the slide bar 10 during sliding and effectively preventing the wobbling problem of the card plate 53 due to poor sliding. This provides users with a safe and reliable operating environment. The optimized design of the slip ring 9 makes the slide bar 10 stable during sliding and less susceptible to external interference.

[0025] Please see Figure 4 A stabilizing ring 11 is fixedly connected to the side wall of the fixing plate 2, and the stabilizing ring 11 is rotatably connected to the metal rod 63.

[0026] Furthermore, the stabilizing ring 11 effectively limits the movement of the metal rod 63, ensuring its safety during use and preventing safety hazards caused by shaking. This provides users with a stable and reliable operating guarantee. The precise limiting of the stabilizing ring 11 keeps the metal rod 63 stable during use and prevents it from shaking.

[0027] Please see Figure 3 There are several support rods 3, and the support rods 3 are distributed in a rectangular shape.

[0028] Furthermore, by reasonably setting the number of support rods 3 to a certain number, the fixed plate 2 can be effectively limited, ensuring the stability between the fixed plate 2 and the limiting rod, avoiding the inconvenience of operation caused by unstable fixing, and greatly improving the user's operation convenience and user experience. The optimized configuration of the number of support rods 3 makes the connection between the fixed plate 2 and the limiting rod more solid, ensuring the stability of the overall structure.

[0029] The specific implementation process of this utility model is as follows: When performing equipment maintenance or repair, the fixing plate 2 needs to be removed first to disassemble the detachable plate heat exchanger 1. The user needs to manually rotate the metal rod 63. The metal rod 63 drives the second helical gear 62 to rotate through a mechanical connection. During the rotation of the second helical gear 62, it further drives the bidirectional screw 51 to rotate synchronously. The rotation of the bidirectional screw 51 is transmitted to the connected screw sleeve 52, causing the screw sleeve 52 to move inward while rotating. The inward movement of the screw sleeve 52 will simultaneously drive the clamping plate 53 to move inward, thereby gradually disengaging the clamping plate 53 from the limiting effect of the clamping slot 54. When the clamping plate 53 is completely disengaged from the clamping slot 54, the fixing plate 2 can be smoothly and completely detached from the support rod 3. At this time, the detachable plate heat exchanger 1 can be removed for thorough cleaning and repair. This design makes the disassembly process simple and quick, greatly improves the disassembly efficiency, achieves the effect of efficient disassembly, and provides great convenience for equipment maintenance and repair.
