Description

Technical Field

[0001] This utility model belongs to the technical field of plate heat exchangers, and specifically relates to a plate heat exchanger with a safe structure. Background Technology

[0002] Plate heat exchangers are a type of high-efficiency heat exchanger consisting of a series of metal plates with a certain corrugated shape stacked together. Thin rectangular channels are formed between the various plates, through which heat exchange occurs. Plate heat exchangers are ideal devices for liquid-liquid and liquid-vapor heat exchange. They have the characteristics of high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, and long service life. Under the same pressure loss conditions, their heat transfer coefficient is 3-5 times higher than that of tubular heat exchangers, their footprint is one-third that of tubular heat exchangers, and their heat recovery rate can be as high as 90%.

[0003] A search revealed that publication number CN 213748030 U relates to a plate heat exchanger with a protective structure. The key technical point is that, by incorporating a fixing mechanism, when the user needs to disassemble and maintain the device, the user presses a button, which moves a push rod into the slot, causing it to contact the push rod and move it into the slot. The user can then pull the fixing rod to separate it from the plate heat exchanger body. By removing the fixing rods sequentially, the user can disassemble and maintain the device, reducing the time required for disassembly, improving work efficiency, and enhancing the user experience.

[0004] The above process facilitates the use of the push-button to drive the insertion rod to abut the locking block, thereby enabling quick disassembly of the device. However, there are still some drawbacks in this process. The disassembly and assembly of plate heat exchangers is relatively troublesome and inefficient. Furthermore, the lack of buffer protection during disassembly and assembly can lead to slippage at one end. In view of this, we propose a new type of plate heat exchanger with a safe structure to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a plate heat exchanger with a safe structure. To achieve the above objectives, it solves the problems of existing plate heat exchangers being cumbersome to assemble and disassemble during use, having low efficiency, and lacking buffer protection during disassembly and assembly, which can lead to one end slipping during disassembly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plate heat exchanger with a safe structure, comprising a base plate, a fixing plate disposed on one side of the upper end of the base plate, a fastening plate disposed on the side of the base plate away from the fixing plate, a plate assembly disposed between the fixing plate and the fastening plate, a connecting plate disposed on the right side of the upper end of the base plate, a buffer mechanism connected between the base plate and the connecting plate, a track plate connected to the upper end of the inner wall of the connecting plate, a sliding groove formed on the fastening plate and the fixing plate, the track plate being slidably disposed within the sliding groove, and a fastening mechanism disposed between the fastening plate and the fixing plate.

[0007] Furthermore, the fastening mechanism includes a hexagonal nut, a sliding rod, a threaded rod, and a threaded hole. The hexagonal nut is fixedly connected to the sliding rod, the sliding rod is slidably disposed within the fixed plate, one end of the sliding rod is fixedly connected to the threaded rod, the fastening plate has a threaded hole, and the threaded rod is slidably disposed within the threaded hole.

[0008] Furthermore, eight fastening mechanisms are provided and symmetrically distributed on both sides of the fixing plate.

[0009] Furthermore, the buffer mechanism includes a rubber block, a plug rod, a limiting block, a buffer cylinder, a cavity, and a return spring. The outer wall of the fastening plate is fixedly connected to the rubber block, the outer wall of the rubber block is fixedly connected to the plug rod, the inner wall of the connecting plate is fixedly connected to the buffer cylinder, the inner cavity of the buffer cylinder has a cavity, the cavity is provided with a return spring, the top of the return spring is provided with a limiting block, and the outer end of the limiting block is connected to one end of the plug rod.

[0010] Furthermore, the insertion rod is inserted into the buffer cylinder, and the diameter of the cavity is the same as the diameter of the limiting block.

[0011] Furthermore, pipes are installed at both the upper and lower ends of the inner cavity of the fixing plate, and mounting plates are fixedly connected to the bottom two sides of the fixing plate, with mounting holes opened on the upper surface of the two mounting plates.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses a hexagonal nut to drive the sliding rod and threaded rod to achieve limit fixation, which facilitates quick assembly and disassembly of the device. The structure is simple and easy to operate. At the same time, the buffer mechanism can provide buffer protection for the fastening plate during assembly and disassembly, ensuring that it can still maintain its state after the fixed plate at one end is removed. The impact force is buffered by the insertion rod driving the internal limit block, which greatly improves the safety performance of the equipment.

[0014] 2. The present invention, through the setting of the track plate and the slide groove, can provide stable performance during the removal of the fixed plate and the plate group, and at the same time, can achieve the limiting and fixing effect on the main body of the equipment when it is removed.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: a plate heat exchanger with a safe structure, including a base plate 5, a fixing plate 1 on one side of the upper end of the base plate 5, a fastening plate 11 on the side of the base plate 5 away from the fixing plate 1, a plate assembly 6 between the fixing plate 1 and the fastening plate 11, a connecting plate 10 on the right side of the upper end face of the base plate 5, a buffer mechanism 9 connecting the base plate 5 and the connecting plate 10, a track plate 7 connected to the upper end of the inner wall of the connecting plate 10, a sliding groove 8 on the fastening plate 11 and the fixing plate 1, and the track plate 7 slidingly disposed in the sliding groove 8, and a fastening mechanism 4 between the fastening plate 11 and the fixing plate 1.

[0022] The fastening mechanism 4 includes a hexagonal nut 401, a slide rod 402, a threaded rod 403, and a threaded hole 404. The hexagonal nut 401 is fixedly connected to the slide rod 402. The slide rod 402 is slidably disposed in the fixed plate 1. One end of the slide rod 402 is fixedly connected to the threaded rod 403. The fastening plate 11 has a threaded hole 404, and the threaded rod 403 is slidably disposed in the threaded hole 404.

[0023] Among them, there are eight fastening mechanisms 4, which are symmetrically distributed on both sides of the fixing plate 1.

[0024] The buffer mechanism 9 includes a rubber block 906, a rod 905, a limiting block 904, a buffer cylinder 901, a cavity 902, and a return spring 903. The outer wall of the fastening plate 11 is fixedly connected to the rubber block 906, the outer wall of the rubber block 906 is fixedly connected to the rod 905, the inner wall of the connecting plate 10 is fixedly connected to the buffer cylinder 901, the inner cavity of the buffer cylinder 901 is provided with a cavity 902, the cavity 902 is provided with a return spring 903, the top of the return spring 903 is provided with a limiting block 904, and the outer end of the limiting block 904 is connected to one end of the rod 905.

[0025] Wherein: the insertion rod 905 is inserted into the buffer cylinder 901, and the diameter of the cavity 902 is the same as the diameter of the limiting block 904.

[0026] Among them: pipes are installed at the upper and lower ends of the inner cavity of the fixing plate 1, and mounting plates 2 are fixedly connected to the bottom two sides of the fixing plate 1. Mounting holes 3 are opened on the upper surface of the two mounting plates 2.

[0027] The working principle of the above embodiment is as follows: When the user needs to disassemble the device, the threaded rod 403 at one end can slide in the threaded hole 404 on the fastening plate 11 by using external force or tools to tighten the hexagonal nut 401. This allows the rod to slide out in conjunction with the sliding rod 402, facilitating the disassembly of the fixing plate 1. At this time, the sliding groove 8 on the top of the fixing plate 1 slides with the track plate 7, which improves stability during disassembly. Under the interference of external force, the internal fastening plate 11 can slide inward through the rubber block 906 on one side, allowing the insertion rod 905 to be inserted into the buffer cylinder 901. At this time, the limiting block 904 connected to the top of the insertion rod 905 can slide in the cavity 902 inside the buffer cylinder 901, while the return spring 903 achieves a buffering effect, which facilitates the buffering of the device and prevents tilting and falling. Conversely, the plate heat exchanger can also be fixedly installed during installation. The mounting plate 2 and mounting hole 3 facilitate the installation of the main body of the equipment, improving the installation efficiency of the equipment.
