Description

Technical Field

[0001] This application relates to the field of plate heat exchanger sealing structure technology, specifically a plate heat exchanger sealing structure with positioning protrusions. Background Technology

[0002] Plate heat exchangers are highly efficient heat exchange devices that achieve heat exchange between two or more fluids through heat transfer between metal plates. They are widely used in HVAC, chemical, food, and pharmaceutical industries, and are characterized by their compact structure, high heat exchange efficiency, and easy assembly and disassembly. However, current plate heat exchangers generally suffer from certain design flaws in their sealing structures. They are primarily fixed using rubber gaskets and bolts. This traditional sealing method, during actual operation, is often affected by multiple factors such as fluid pressure fluctuations, temperature changes, and mechanical vibrations, leading to varying degrees of displacement and shaking of the heat exchange plates. This unstable mechanical state not only causes uneven compression of the gaskets but also leads to relative positional shifts between the heat exchange plates, resulting in localized gaps on the sealing surface. Utility Model Content

[0003] The purpose of this utility model is to provide a plate heat exchanger sealing structure with positioning protrusions, which solves the problem that current plate heat exchanger sealing structures, which are fixed by sealing and bolts, are prone to shaking and displacement of the heat exchange plate during use, which can easily lead to leakage and poor sealing.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a plate heat exchanger sealing structure with positioning protrusions, comprising plate heat exchanger plates, mounting brackets provided on both sides of the plate heat exchanger plates, a support plate fixedly connected to the inner side of the mounting brackets, a sealing ring provided on the inner side of the plate heat exchanger plates, inclined blocks fixedly connected to both the front and back sides of the plate heat exchanger plates, a snap-fit ​​assembly provided on the outer side of the support plate, a transmission assembly provided on the top of the plate heat exchanger plates, and protrusions fixedly connected to the side walls of the plate heat exchanger plates, the protrusions snapping into the plate heat exchanger plates; The snap-fit ​​assembly is used to connect multiple plate heat exchanger plates; The transmission assembly is used to drive the snap-fit ​​assembly.

[0005] Preferably, the snap-fit ​​assembly includes a snap-fit ​​block located on the outer side of the plate heat exchanger plates. The snap-fit ​​block is slidably connected to an inclined block. A connecting plate is laterally fixedly connected to the outer side of the snap-fit ​​block. A threaded sleeve is fixedly connected to the inner side of the snap-fit ​​block. A bidirectional screw is vertically rotatably connected to the inside of the support plate. The bidirectional screw is threadedly connected to the threaded sleeve.

[0006] Preferably, the transmission assembly includes a worm gear, which is fixedly connected to the top of the bidirectional screw. There are two worm gears, and a worm gear assembly is provided on the top of the plate heat exchanger plates, which meshes with the worm gear.

[0007] Preferably, a sliding rod is vertically fixedly connected to the inner side of the support plate, and the sliding rod is slidably connected to the locking block.

[0008] Preferably, a protective frame is fixedly connected to the top of the support plate, and the protective frame is rotatably connected to the worm gear assembly.

[0009] Preferably, the number of protrusions is several, and the protrusions are evenly distributed in a rectangular shape.

[0010] Preferably, an operating block is fixedly connected to the front of the worm gear assembly, and the operating block is located on the front side of the plate heat exchanger plates.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model achieves firm fixing and precise sealing of plate heat exchanger plates through the synergistic action of the snap-fit ​​assembly and the transmission assembly. In the snap-fit ​​assembly, the bidirectional screw drives the screw sleeve to tightly engage the snap-fit ​​block and the tilting block. Combined with the multi-point limiting design of the protrusions, it effectively prevents medium leakage caused by the plate heat exchanger plates shaking due to external force or misalignment, ensuring sealing reliability. The transmission assembly, through worm gear meshing, ensures the smooth operation of the bidirectional screw, avoids shaking caused by uneven force, further improves fixing stability, and fundamentally solves the problem of poor sealing in traditional structures.

[0012] 2. This utility model avoids motion deviation by precisely guiding the locking block with a sliding rod, and the protective frame ensures the stability of the worm gear assembly's rotation trajectory, reducing the vibration risk of the transmission components. The ergonomic design of the operating block simplifies the rotation operation of the worm gear assembly and improves the user's operating experience. At the same time, the optimization of the auxiliary structure further ensures the overall system's operational reliability and ease of maintenance. Attached Figure Description

Detailed Implementation

[0015] 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.

[0016] Please see Figure 1-4 A plate heat exchanger sealing structure with positioning protrusions includes plate heat exchanger plates 1, mounting brackets 2 on both sides of the plate heat exchanger plates 1, a support plate 3 fixedly connected to the inner side of the mounting brackets 2, a sealing ring 4 on the inner side of the plate heat exchanger plates 1, inclined blocks 5 fixedly connected to the front and back of the plate heat exchanger plates 1, a snap-fit ​​assembly 6 on the outer side of the support plate 3, a transmission assembly 7 on the top of the plate heat exchanger plates 1, and protrusions 8 fixedly connected to the side walls of the plate heat exchanger plates 1, the protrusions 8 snapping with the plate heat exchanger plates 1; The snap-fit ​​assembly 6 is used to connect multiple plate heat exchanger plates 1; The transmission assembly 7 is used to drive the snap-fit ​​assembly 6.

[0017] Please see Figure 4 The snap-fit ​​assembly 6 includes a snap-fit ​​block 61, which is located on the outside of the plate heat exchanger plate 1. The snap-fit ​​block 61 is slidably connected to the inclined block 5. A connecting plate 62 is horizontally fixedly connected to the outside of the snap-fit ​​block 61, and a threaded sleeve 63 is fixedly connected to the inside of the snap-fit ​​block 61. A bidirectional screw 64 is vertically rotatably connected inside the support plate 3, and the bidirectional screw 64 is threadedly connected to the threaded sleeve 63.

[0018] Furthermore, the snap-fit ​​assembly enables effective transmission control of the snap-fit ​​block 61. When the snap-fit ​​block 61 moves under the action of transmission, it will form a tight snap-fit ​​relationship with the tilting block 5. The special inclined surface design of the tilting block 5 can generate a stable fixing force, which firmly fixes the plate heat exchanger plate 1 in the working position, thereby effectively preventing the plate heat exchanger plate 1 from shaking or tilting due to external force, and avoiding the problem of medium leakage caused by this.

[0019] Please see Figure 2The transmission assembly 7 includes a worm gear 71, which is fixedly connected to the top of the bidirectional screw 64. There are two worm gears 71. A worm gear assembly 72 is provided on the top of the plate heat exchanger plate 1, and the worm gear assembly 72 meshes with the worm gear 71.

[0020] Furthermore, the transmission component 7 transmits power through a precise mechanical structure, ensuring that the bidirectional screw 64 remains stable during operation. This significantly reduces the risk of the screw wobbling due to uneven force distribution. This stable transmission method ensures that the bidirectional screw can continuously and reliably perform transmission operations, improving the overall system reliability.

[0021] Please see Figure 4 A slide rod 9 is vertically fixed to the inner side of the support plate 3, and the slide rod 9 is slidably connected to the locking block 61.

[0022] Furthermore, through the setting of the slide bar 9 mechanism, the movement trajectory of the locking block 61 is strictly controlled by the precise guidance of the slide bar 9, ensuring that the locking block 61 remains stable during operation. This design effectively avoids unnecessary shaking of the locking block 61 due to external interference, greatly improving the convenience of operation and the stability of the system, and providing users with a smoother operating experience.

[0023] Please see Figure 2 A protective frame 10 is fixedly connected to the top of the support plate 3, and the protective frame 10 is rotatably connected to the worm gear assembly 72.

[0024] Furthermore, through the setting of the protective frame 10, the protective frame 10 ensures that the worm gear assembly 72 maintains a stable rotation trajectory during operation through precise mechanical coordination, effectively preventing the worm gear assembly 72 from deviating or shaking due to vibration or external force. This precise limiting design ensures the rotational accuracy of the worm gear assembly 72 and improves the reliability of the entire transmission system.

[0025] Please see Figure 4 There are several bumps 8, and the bumps 8 are evenly distributed in a rectangular shape.

[0026] Furthermore, by setting the protrusions 8, and by rationally arranging several protrusions 8, multiple plate heat exchanger plates 1 can be precisely limited at the same time. This multi-point limiting method not only improves the efficiency of the limiting operation, but also effectively prevents the positional misalignment of multiple plate heat exchanger plates 1 due to relative movement, thus ensuring the overall coordination and stability of the system.

[0027] Please see Figure 2 An operating block 11 is fixedly connected to the front of the worm gear assembly 72, and the operating block 11 is located on the front side of the plate heat exchanger plate 1.

[0028] Furthermore, the operation block 11, with its ergonomic shape design, allows the operator to easily rotate the worm gear assembly 72. This design not only reduces the difficulty of operation but also effectively prevents the worm gear assembly 72 from shaking during operation through a stable mechanical structure, greatly improving the user's operating experience and the reliability of the system.

[0029] The specific implementation process of this utility model is as follows: When it is necessary to fix multiple plate heat exchanger plates 1, precise alignment and fixing can be achieved by setting the protrusion 8 structure. In the specific operation process, the user only needs to manually rotate the operating block 11. The operating block 11 is connected to the worm gear assembly 72 through a mechanical linkage device, thereby driving the worm gear assembly 72 to rotate smoothly. The rotational motion of the worm gear assembly 72 is further transmitted to the worm wheel 71 system, so that the worm wheel 71 produces a precise rotational motion. The rotation of the worm wheel 71 will simultaneously drive two symmetrically arranged bidirectional screws 64. These two screws adopt a precision thread design, which can convert rotational motion into linear motion. When in use, the threaded sleeve 63 will move precisely along the screw axis. The movement of the threaded sleeve 63 will drive the connected locking block 61 assembly, causing multiple locking blocks 61 to move synchronously towards the center position. The special design of these locking blocks 61 can push the tilting block 5 to produce a clamping action. By applying force evenly at multiple points, the connection between multiple plate heat exchanger plates 1 is ensured to be both firm and stable. This linkage mechanism design makes the entire fixing process easy to operate, while effectively preventing loosening. It achieves a highly efficient and reliable positioning and sealing effect. The entire system achieves force amplification and precise motion control through multi-stage transmission, ensuring the stability and reliability of the fixing process.

[0030] 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.
