Abstract
Description
Technical Field
[0001] This invention relates to the field of gasket connection technology for plate heat exchangers, and specifically to an anti-detachment gasket for heat exchange plates. Background Technology
[0002] The most common mechanical attachment method for gaskets and plates in plate heat exchangers is the hook-and-loop fastener system. The hook's claws extend from the outer edge of the plate, securing it to the outer edge and thus fixing the gasket. However, current technology mostly uses a single hook-and-loop fastener system. In applications requiring frequent disassembly and cleaning of plate heat exchangers, this structure is prone to damage and detachment; especially with long plate-type fasteners and during plate assembly clamping, it is extremely easy for them to fall off, causing leaks during pressure testing and affecting production efficiency.
[0003] Therefore, we designed a new type of double hook pad. Each hook assembly includes two connecting arms and three hooks. By enhancing the adhesion strength to the pad, we prevent the connecting arms from deforming and breaking due to pressure and lack of deformation space during the clamping process of the plate assembly. At the same time, the clamping of the plate assembly also presses and fixes the connecting arms to prevent the pad from deviating during the clamping process. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides an anti-detachment pad for heat exchange plates, which can solve the problems of low strength and easy detachment of existing pads and plates through mechanical adhesion, and improve the stability of the pad under frequent disassembly and high-pressure conditions.
[0005] In a first aspect, the present invention provides an anti-detachment pad for a heat exchange plate, comprising: an anti-detachment pad body and a plate body; the plate body is disposed on the anti-detachment pad body and is used to cooperate with a hanging groove on the heat exchange plate; the anti-detachment pad body is provided with a first connecting arm and a second connecting arm; wherein the first connecting arm and the second connecting arm are both disposed on one side of the anti-detachment pad body; the plate body is provided with a pad groove, a first peak, a first trough, a first connecting arm groove, a second peak, a second trough, a second connecting arm groove, and a third peak; the pad body is connected to the first connecting arm and the second connecting arm; the pad body is disposed in the pad groove; the first connecting arm groove and the second connecting arm groove are both disposed on the outside of the pad groove; and the thickness of the pad groove is the thickness of the first connecting arm and the second connecting arm after compression; the first peak, the first trough, the second peak, the second trough, and the third peak are sequentially arranged along the outer edge sidewall of the plate body.
[0006] Furthermore, it also includes an outer connecting arm, one side of which is provided with a first hook, a second hook, and a third hook. In practical applications, the purpose of this design is to further enhance the connection effect and effectively ensure the connection stability between the anti-detachment pad body and the plate body.
[0007] Furthermore, one side of the outer connecting arm is smooth and fits snugly against the main body of the plate. In actual design, this smooth surface increases the contact area between the outer connecting arm and the main body of the plate, effectively improving stability and reducing displacement of the anti-detachment pad.
[0008] Furthermore, the first hook is installed between the first crest and the first trough; the second hook is installed between the second crest and the second trough; and the third hook is installed between the second trough and the third crest. In practical applications, when the anti-detachment pad body is placed and attached to the pad groove, it serves to fix the pad. The single-group multiple hook configuration provides a stronger fixing effect and a higher tolerance for errors. It also serves to fix the pad even if one hook fails or breaks. Simultaneously, the outer connecting arm mainly connects the first and second connecting arms to the first, second, and third hooks, thus fixing the pad and preventing longitudinal and lateral displacement of the anti-detachment pad body. Furthermore, the outer connecting arm is also equipped with two fixing blocks. One fixing block is located between the first and second hooks and engages with the first and second wave crests; the other fixing block is located between the second and third hooks and engages with the second and third wave crests. In practical applications, the purpose of this design is to achieve a secure engagement with the three hooks on both sides, thereby further ensuring connection stability.
[0009] Furthermore, both the first and second connecting arms are located on the mating protrusion, which abuts against one side of the outer connecting arm. In practical applications, the purpose of this design is to achieve reinforcement and ensure stability.
[0010] As can be seen from the above technical solution, the beneficial effects of the anti-detachment pad for heat exchange plates provided by the present invention are as follows: (1) High-strength fixing: The three-claw redundant design ensures that the overall fixing is not affected by the failure of a single point; (2) Anti-displacement: The groove and compression space design of the connecting arm prevent the rubber pad from shifting during the clamping process; (3) Low maintenance cost: suitable for frequent disassembly scenarios, reducing maintenance frequency and cost; (4) High production efficiency: Reduces the failure rate of the machine and improves the assembly efficiency of the heat exchanger.

Detailed Implementation
[0013] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.
[0014] The basic implementation examples are as follows: Figures 1 to 5 As shown: like Figure 1 - Figure 5 As shown in the figure, the anti-detachment pad for heat exchange plates provided in this embodiment can solve the problems of low strength and easy detachment of existing pads and plates through mechanical adhesion, and improve the stability of the pad under frequent disassembly and high pressure conditions.
[0015] In a first aspect, the present invention provides an anti-detachment pad for a heat exchange plate, comprising: an anti-detachment pad body 1 and a plate body 16; the plate body 16 is disposed on the anti-detachment pad body 1 and is used to cooperate with a hanging groove on the heat exchange plate; the anti-detachment pad body 1 is provided with a first connecting arm 2 and a second connecting arm 3; wherein the first connecting arm 2 and the second connecting arm 3 are both disposed on one side of the anti-detachment pad body 1; the plate body 16 is provided with a pad groove 8, a first crest 9, a first trough 10, a first connecting arm groove 11, a second crest 12, and a third connecting arm groove 13. The system includes a second trough 13, a second connecting arm groove 14, and a third peak 15; the rubber pad body is connected to the first connecting arm 2 and the second connecting arm 3; the rubber pad body is disposed within the rubber pad groove 8; the first connecting arm groove 11 and the second connecting arm groove 14 are both located on the outside of the rubber pad groove 8; and the thickness of the rubber pad groove 8 is the thickness of the first connecting arm 2 and the second connecting arm 3 after compression; the first peak 9, the first trough 10, the second peak 12, the second trough 13, and the third peak 15 are sequentially arranged along the outer edge sidewall of the plate body 16. High-strength fixing: redundant three-claw design, single-point failure does not affect overall fixing; anti-displacement: connecting arm groove and compression space design prevent rubber pad displacement during clamping; low maintenance cost: suitable for frequent disassembly scenarios, reducing maintenance frequency and cost; high production efficiency: reduces installation failure rate and improves heat exchanger assembly efficiency.
[0016] In this embodiment, an outer connecting arm 4 is also included, and a first hook 5, a second hook 6, and a third hook 7 are respectively provided on one side of the outer connecting arm 4. In practical applications, the purpose of this design is to further enhance the connection effect and effectively ensure the connection stability between the anti-detachment pad body 1 and the plate body 16.
[0017] In this embodiment, one side of the outer connecting arm 4 is smooth and fits against the plate body 16. In actual design, this smooth surface increases the contact area between the outer connecting arm 4 and the plate body 16, effectively improving stability and reducing displacement of the anti-detachment pad body 1.
[0018] In this embodiment, the first hook 5 is installed between the first crest 9 and the first trough 10; the second hook 6 is installed between the second crest 12 and the second trough 13; and the third hook 7 is installed between the second trough 13 and the third crest 15. In practical applications, when the anti-detachment pad body 1 is placed and attached to the pad groove 8, it serves to fix the pad. The single-group multiple hooks have a stronger fixing effect and fault tolerance. When a hook in a single group of hooks fails or breaks, it can also serve to fix the pad. At the same time, the outer connecting arm 4 mainly connects the first connecting arm 2 and the second connecting arm 3 with the first hook 5, the second hook 6 and the third hook 7; it serves to fix the pad and prevent the anti-detachment pad body 1 from shifting longitudinally or laterally. In this embodiment, the outer connecting arm 4 is further provided with a fixing block 17. The fixing block 17 has two locations: one is located between the first hook 5 and the second hook 6, and engages with the first wave crest 9 and the second wave crest 12; the other fixing block 17 is located between the second hook 6 and the third hook 7, and engages with the second wave crest 12 and the third wave crest 15. In practical applications, the purpose of this design is to achieve a secure engagement with the three hooks on both sides, thereby further ensuring connection stability.
[0019] In this embodiment, both the first connecting arm 2 and the second connecting arm 3 are disposed on the fitting protrusion 18, which abuts against one side of the outer connecting arm 4. In practical applications, the purpose of this design is to achieve reinforcement and ensure stability.
[0020] In summary, this anti-detachment pad for heat exchange plates is not only reasonably designed and easy to operate, but also improves structural fixing strength and achieves resistance to longitudinal and lateral displacement deflection. At the same time, it has low overall maintenance costs and high production efficiency. Therefore, this device is suitable for industry promotion.
