Abstract

This utility model proposes a pressure-bearing plate-tooth heat exchanger structure, particularly relating to the technical field of plate-tooth heat exchangers. The structure includes a plate-tooth heat exchanger. In use, after the plates are installed and fixed, a first bolt is used to sequentially penetrate the first and second side plates, then secured with a nut. Next, a sleeve plate on a limiting frame is slidably fitted onto the outside of one end of the first bolt. During this fitting process, the fixing plate is pulled, causing it to deform. Once one side of the sleeve plate is tightly fitted against the outside of the nut, the fixing plate is released, and a locking block on the fixing plate engages in a slot on one side of the limiting frame, thus pre-fixing the limiting frame. Then, a second bolt is used to penetrate the limiting frame and threadedly connect to the second side plate, thereby installing and fixing the limiting frame. The sleeve plate can limit the nut, preventing it from detaching, ensuring the first bolt has sufficient pre-tightening force to resist the tendency of the plates to separate due to internal pressure, resulting in better pressure bearing.

Description

Technical Field

[0001] This utility model relates to the field of plate-tooth heat exchanger technology, and in particular to a pressure-bearing plate-tooth heat exchanger structure. Background Technology

[0002] A plate-tooth heat exchanger is a highly efficient and compact heat exchange device, typically composed of baffles, fins, seals, and guide vanes. Its core structure includes a set of rectangular metal plates pressed within a frame. These plates are usually embossed with corrugated protrusions and have distribution holes at the four corners. Rubber or fluororubber gaskets are placed between adjacent plates, forming narrow and long fluid channels. Since the frame needs to withstand the overall pressure of the plate assembly, sufficient preload is required via bolts to resist the tendency for plate separation caused by internal pressure. Therefore, a pressure-bearing plate-tooth heat exchanger structure is necessary. Utility Model Content

[0003] The purpose of this invention is to propose a pressure-bearing plate toothed heat exchanger structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a plate-tooth heat exchanger, comprising a first side plate and a second side plate, with a pressure-bearing mechanism between the first and second side plates. The pressure-bearing mechanism includes a first bolt, a fixing plate, a locking block, a limiting frame, a sleeve plate, a locking groove, a through hole, and a second bolt. The first bolt is inserted through the outer sides of the first and second side plates, with a nut threaded onto one end of the first bolt. A fixing plate is fixedly connected to one side of the second side plate, and a locking block is integrally formed on one side of the fixing plate. A sleeve plate is fitted onto the outer side of one end of the first bolt, and a limiting frame is integrally formed on one side of the sleeve plate. A locking groove is formed on one side of the limiting frame, and a through hole is formed on the outer side of the limiting frame. A second bolt is inserted into the inner side of the through hole.

[0005] Preferably, three sleeve plates are provided, and one side of the sleeve plate is tightly fitted to the outer side of the nut.

[0006] Preferably, the second bolt is threaded to the second side plate, and the limiting frame is fixedly connected to the second side plate by the second bolt.

[0007] Preferably, a support mechanism is provided at the bottom of the first side plate and the second side plate. The support mechanism includes a first threaded post, a first base plate, an end plate, a third bolt, a second threaded post, a second base plate, a groove, and a fourth bolt. The first threaded post is inserted through one side of the first side plate, and the first base plate is welded and fixed to one end of the first threaded post. An end plate is integrally formed at one end of the first base plate. The second threaded post is inserted through one side of the second side plate, and the second base plate is fixedly connected to one end of the second threaded post. A groove is provided at one end of the second base plate, and the fourth bolt is inserted through the top of one end of the second base plate.

[0008] Preferably, one end of the fourth bolt is threaded to the end plate, and nuts are threaded to the outer sides of both the first and second threaded posts.

[0009] Preferably, the outer wall of the end plate is adapted to the inner wall of the groove, and the end plate is slidably inserted into the groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, after the plates are installed and fixed, a first bolt is used to sequentially penetrate the first and second side plates, and then a nut is used to lock and fix them. Next, the sleeve plate on the limiting frame is slidably fitted onto the outside of one end of the first bolt. During the fitting process, the fixing plate is pulled, causing it to deform. After one side of the sleeve plate is tightly fitted with the outside of the nut, the fixing plate is released, and the locking block on the fixing plate engages in the slot on one side of the limiting frame, thus pre-fixing the limiting frame. Then, a second bolt is used to penetrate the limiting frame and threadedly connect to the second side plate, thereby installing and fixing it. The limiting bracket and the sleeve plate can limit the nut to prevent it from coming loose, so that the first bolt has sufficient preload to resist the tendency of the plates to separate due to internal pressure, thus achieving a better pressure bearing effect. The first threaded post is inserted through and connected to the first side plate, and then tightened with a nut to fix it, thereby installing and fixing the first base plate. The second base plate and the second side plate are installed and fixed in the same way, so that the end plate slides into the groove. Then, the fourth bolt is inserted through the second base plate and threaded to connect the end plate, thereby fixing the two base plates. Finally, the two base plates are fixed to the ground with the third bolt. The support of the two base plates can ensure that the support of the plate tooth heat exchanger is more stable.

[0018] Example

[0019] Please see Figure 1-4This utility model discloses a pressure-bearing plate-tooth heat exchanger structure, comprising a plate-tooth heat exchanger 1, which includes a first side plate 2 and a second side plate 3. A pressure-bearing mechanism is provided between the first side plate 2 and the second side plate 3. The pressure-bearing mechanism includes a first bolt 4, a fixing plate 5, a locking block 6, a limiting frame 7, a sleeve plate 8, a locking groove 9, a through hole 10, and a second bolt 11. The first bolt 4 is inserted through the outer sides of the first side plate 2 and the second side plate 3, and a nut is threaded to one end of the first bolt 4. The fixing plate 5 is fixedly connected to one side of the second side plate 3, and a locking block 6 is integrally formed on one side of the fixing plate 5. A sleeve plate 8 is fitted on the outer side of one end of the first bolt 4, and a limiting frame 7 is integrally formed on one side of the sleeve plate 8. A locking groove 9 is opened on one side of the limiting frame 7, and a through hole 10 is opened on the outer side of the limiting frame 7. A second bolt 11 is inserted into the inner side of the through hole 10. When using bolt 11, after the plates are installed and fixed, the first bolt 4 is used to pass through the first side plate 2 and the second side plate 3 in sequence, and then the bolt is locked with a nut. Then, the sleeve plate 8 on the limiting frame 7 is slidably fitted onto the outside of one end of the first bolt 4. During the fitting process, the fixing plate 5 is pulled to deform the fixing plate 5. After one side of the sleeve plate 8 is tightly fitted with the outside of the nut, the fixing plate 5 is released. The locking block 6 on the fixing plate 5 is engaged in the locking groove 9 on one side of the limiting frame 7, thereby pre-fixing the limiting frame 7. Then, the second bolt 11 is used to pass through the limiting frame 7 and threadedly connected to the second side plate 3, thereby installing and fixing the limiting frame 7. The sleeve plate 8 can limit the nut and play an anti-loosening role, so that the first bolt 4 has sufficient pre-tightening force to resist the tendency of the plates to separate due to internal pressure, and play a better pressure-bearing role.

[0020] Furthermore, there are three sleeve plates 8, one side of which fits tightly against the outside of the nut.

[0021] Furthermore, the second bolt 11 is threadedly connected to the second side plate 3, and the limiting frame 7 is fixedly connected to the second side plate 3 by the second bolt 11.

[0022] For ease of installation, a support mechanism is provided at the bottom of the first side plate 2 and the second side plate 3. The support mechanism includes a first threaded post 12, a first base plate 13, an end plate 14, a third bolt 15, a second threaded post 16, a second base plate 17, a groove 18, and a fourth bolt 19. The first threaded post 12 is inserted through one side of the first side plate 2, and the first base plate 13 is welded and fixed to one end of the first threaded post 12. The end plate 14 is integrally formed at one end of the first base plate 13. The second threaded post 16 is inserted through one side of the second side plate 3, and the second base plate 17 is fixedly connected to one end of the second threaded post 16. The groove 18 is provided at one end of the second base plate 17. A fourth bolt 19 is inserted through the top of one end of plate 17. A third bolt 15 is inserted through the top of both the first base plate 13 and the second base plate 17. The first threaded post 12 is inserted through the first side plate 2 and tightened with a nut to fix it, thereby installing and fixing the first base plate 13. The second base plate 17 and the second side plate 3 are installed and fixed in the same way, so that the end plate 14 slides into the groove 18. Then, the fourth bolt 19 is inserted through the second base plate 17 and threaded to connect the end plate 14, thereby fixing the two base plates. Then, the two base plates are fixed to the ground with the third bolt 15. The support of the two base plates can ensure that the support of the plate tooth heat exchanger 1 is more stable.

[0023] Furthermore, one end of the fourth bolt 19 is threaded to the end plate 14, and nuts are threaded to the outer sides of both the first threaded post 12 and the second threaded post 16.

[0024] Furthermore, the outer wall of the end plate 14 is adapted to the inner wall of the groove 18, and the end plate 14 is slidably inserted into the groove 18.

[0025] Working principle: In use, after the plates are installed and fixed, the first bolt 4 is used to pass through the first side plate 2 and the second side plate 3 in sequence, and then the bolt is tightened with a nut. Then, the sleeve plate 8 on the limiting frame 7 is slidably fitted onto the outside of one end of the first bolt 4. During the fitting process, the fixing plate 5 is pulled, causing the fixing plate 5 to deform. After one side of the sleeve plate 8 is tightly fitted with the outside of the nut, the fixing plate 5 is released, and the locking block 6 on the fixing plate 5 engages in the locking groove 9 on one side of the limiting frame 7, thereby pre-fixing the limiting frame 7. Then, the second bolt 11 is used to pass through the limiting frame 7 and threaded onto the second side plate 3, thereby installing and fixing the limiting frame 7. The sleeve plate 8 can limit the nut, which can prevent it from falling off, so that the first bolt 4 has sufficient pre-tightening force to resist... The plate separation tendency caused by internal pressure provides better pressure resistance. The first threaded post 12 is inserted through and connected to the first side plate 2, and tightened with a nut to fix it, thereby installing and fixing the first base plate 13. The second base plate 17 and the second side plate 3 are installed and fixed in the same way, so that the end plate 14 slides into the groove 18. Then, the fourth bolt 19 is inserted through the second base plate 17 and threaded to connect the end plate 14, thereby fixing the two base plates. Then, the two base plates are fixed to the ground with the third bolt 15. The support of the two base plates can ensure that the support of the plate toothed heat exchanger 1 is more stable. The plate toothed heat exchanger 1 is manufactured by Wuxi Meijing Heat Exchange Equipment Co., Ltd., and the model is MJ032. Its structure and working principle are existing technologies and will not be described in detail here.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
