Description

Technical Field

[0001] This utility model relates to the field of thermal insulation cover technology, and in particular to a quick-release thermal insulation cover. Background Technology

[0002] Plate heat exchangers, as key equipment for heat exchange in industrial production, are widely used in chemical, food, and HVAC industries. They transfer heat through the close contact between metal plates. During operation, the plate surface temperature is high. If exposed to air, significant heat loss occurs due to thermal radiation and convection, reducing heat exchange efficiency and increasing energy consumption. Furthermore, the high-temperature surface can cause burns to operators, and heat loss in low-temperature environments can lead to condensation and icing around the equipment, affecting equipment lifespan and the workshop environment. Therefore, insulation covers, as supporting equipment for plate heat exchangers, effectively reduce heat loss and ensure operational safety, making them essential devices for improving the economic efficiency and safety of equipment operation.

[0003] However, existing plate heat exchanger insulation covers have significant shortcomings in terms of ease of disassembly. Traditional insulation covers are mostly installed using bolt fixing or welding splicing methods, requiring tools such as wrenches for disassembly. Furthermore, the disassembly process necessitates unscrewing each bolt or disassembling the spliced ​​structure, making the operation cumbersome and time-consuming. For plate heat exchangers that require regular cleaning and maintenance, frequent disassembly of the insulation cover significantly extends maintenance time and reduces production efficiency. Utility Model Content

[0004] To address the technical problem of inconvenient disassembly of the insulation cover of existing plate heat exchangers, this utility model provides a quick-release insulation cover.

[0005] The technical solution adopted by this utility model is: a quick-release heat insulation cover, including a first heat insulation cover and a second heat insulation cover. The first heat insulation cover and the second heat insulation cover are both fixedly connected to the outside of a fixed frame. The outside of the fixed frame is provided with at least one set of positioning grooves. The two sides of the first heat insulation cover are respectively slidably connected to a first snap-fit ​​plate and a second snap-fit ​​plate. The side walls of the first snap-fit ​​plate and the second snap-fit ​​plate are fixedly connected to positioning blocks. The outside of the first snap-fit ​​plate and the second snap-fit ​​plate is also provided with a locking component.

[0006] A further feature of this invention is that guide plates are fixedly connected to all four sides of the opening end of the second heat insulation cover, and the guide plates are slidably inserted into the first heat insulation cover.

[0007] A further feature of this invention is that the top of one of the fixed frames is provided with a sliding groove, the tops of the first snap-fit ​​plate and the second snap-fit ​​plate are both fixedly connected to a connecting plate, and the bottom of the connecting plate is fixedly connected to a slider, which is slidably connected to the sliding groove.

[0008] The present invention is further configured such that the locking component includes a card seat and a fixing seat, a first connecting frame is fixedly connected to the top of the first card plate, the first connecting frame is fixedly connected to the card seat, the card seat is provided with a slot, a second connecting frame is fixedly connected to the top of the second card plate, a fixing seat is fixedly connected to the outside of the second connecting frame, an elastic plate is fixedly connected to the outside of the fixing seat, and a card plate is fixedly connected to one end of the elastic plate.

[0009] A further feature of this invention is that a spring connects the two sets of connecting plates.

[0010] A further feature of this invention is that the exterior of both the first and second insulation covers is provided with multiple sets of mounting holes.

[0016] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described below.

[0017] To address the problems existing in the background art, this application proposes the following technical solution: a quick-release thermal insulation cover, comprising a first thermal insulation cover 1 and a second thermal insulation cover 2. Thermal insulation material, such as thermal insulation foam board, is fixedly installed inside the first and second thermal insulation covers 1 and 2. Multiple sets of mounting holes are provided on the exterior of both the first and second thermal insulation covers 1 and 2. A fixing frame 5 is fixedly connected to the exterior of both the first and second thermal insulation covers 1. At least one set of positioning grooves 7 is provided on the outer side of each fixing frame 5. A first snap-fit ​​plate 3 and a second snap-fit ​​plate 4 are slidably connected to both sides of the first thermal insulation cover 1. Positioning blocks 9 are fixedly connected to the side walls of both the first and second snap-fit ​​plates 3 and 4. Both the positioning blocks 9 and the positioning grooves 7 are I-shaped structures. Locking components are also provided on the exterior of the first and second snap-fit ​​plates 3 and 4. Guide plates 8 are fixedly connected to the four sides of the opening end of the second thermal insulation cover 2, and the guide plates 8 are slidably inserted into the first thermal insulation cover 1. One of the fixed frames 5 has a sliding groove 6 at its top. A connecting plate 11 is fixedly connected to the top of both the first snap-fit ​​plate 3 and the second snap-fit ​​plate 4. A slider is fixedly connected to the bottom of the connecting plate 11, and the slider is slidably connected to the sliding groove 6. The first insulation cover 1 and the second insulation cover 2 are used together to completely enclose the equipment requiring insulation (such as a plate heat exchanger). The double-layer structure enhances the insulation effect and reduces heat loss. Multiple sets of mounting holes on the exterior of both covers can be used for pipes and wiring to pass through the equipment, ensuring that the installation of the insulation cover does not affect the normal operation of the equipment, while also preventing insulation leaks caused by pipes penetrating the cover.

[0018] The fixing frame 5 is fixed to the outside of the insulation cover, which not only enhances the structural strength of the edge of the insulation cover and prevents deformation, but also provides an installation base for the positioning groove 7. The positioning block 9 and the positioning groove 7 adopt an I-shaped structure. This shape fits together so that the two can interlock after being inserted, avoiding lateral or longitudinal loosening, ensuring that the first insulation cover 1 and the second insulation cover 2 are tightly connected, and reducing heat exchange at the gaps.

[0019] The first snap-fit ​​plate 3 and the second snap-fit ​​plate 4 slide to allow the positioning block 9 to dock or separate from the positioning groove 7, making operation convenient. The guide plate 8 of the second insulation cover 2 slides into the first insulation cover 1, serving a positioning and guiding function, allowing the two to be quickly aligned during splicing, improving installation efficiency, and further enhancing the sealing of the connection.

[0020] The sliding groove 6 at the top of the fixed frame 5 cooperates with the slider at the bottom of the connecting plate 11 to provide a track for the sliding of the first snap-fit ​​plate 3 and the second snap-fit ​​plate 4, ensuring a smooth and stable sliding process and avoiding jamming. This sliding structure allows for more flexible adjustment of the positions of the first snap-fit ​​plate 3 and the second snap-fit ​​plate 4, facilitating precise control of the fit between the positioning block 9 and the positioning groove 7 according to the splicing status of the insulation cover, ensuring a firm overall connection, and improving the installation stability and insulation effect of the insulation cover.

[0021] In this embodiment, the locking assembly includes a card holder 13 and a fixed base 16. A first connecting frame 12 is fixedly connected to the top of the first card plate 3, and the first connecting frame 12 is fixedly connected to the card holder 13. The card holder has a slot 14 inside. A second connecting frame 15 is fixedly connected to the top of the second card plate 4, and a fixed base 16 is fixedly connected to the outside of the second connecting frame 15. An elastic plate 18 is fixedly connected to the outside of the fixed base 16, and a card plate 17 is fixedly connected to one end of the elastic plate 18. A spring 10 is connected between the two sets of connecting plates 11. The card holder 13 and the fixed base 16 in the locking assembly are respectively connected to the first and second card plates 4. The locking of the two is achieved by the card plate 17 engaging with the slot 14, preventing the card plate from accidentally sliding during use and causing the positioning block 9 to disengage from the positioning groove 7, thus ensuring the stability of the insulation cover connection.

[0022] The first connecting bracket 12 and the second connecting bracket 15 fix the card seat 13 and the fixed seat 16 to the corresponding card plates, ensuring that the locking components move synchronously with the card plates and that the locking action is coordinated with the sliding of the card plates. The elastic plate 18 is elastic. When the card plate 17 is inserted into the slot 14, it can use its own elasticity to make the card plate 17 fit tightly against the inner wall of the slot 14, enhancing the firmness of the engagement. When unlocking is required, pressing the card plate 17 will compress the elastic plate 18, causing the card plate 17 to disengage from the slot 14. The operation is simple and effortless.

[0023] The spring 10 between the two sets of connecting plates 11 is stretched when the first latching plate 3 and the second latching plate 4 approach each other, storing elastic potential energy. When unlocking, the elastic force of the spring 10 pushes the latching plates apart, automatically causing the positioning block 9 to disengage from the positioning groove 7, facilitating the disassembly of the insulation cover. This elastic reset design eliminates the need for extra force during disassembly, reducing operational difficulty. Especially in scenarios where frequent disassembly of the insulation cover is required for equipment maintenance, it can significantly improve work efficiency and reduce manpower consumption.

[0024] In summary, based on the shape and dimensions of the plate heat exchanger, the first insulation cover 1 and the second insulation cover 2 are respectively fitted onto the outside of the equipment from both sides. During the installation process, ensure that the heat exchanger pipes accurately pass through the through holes on the outside of the insulation covers to avoid the pipes being squeezed or the insulation covers being misaligned. After the pipes pass through the through holes, the structure around the through holes will fit tightly against the pipe surface, reducing heat loss from gaps.

[0025] Next, the first snap-fit ​​plate 3 and the second snap-fit ​​plate 4 are pushed to slide along the slide groove 6 towards the center. As they approach each other, the positioning block 9 on the side wall gradually inserts into the positioning groove 7 of the fixed frame 5. The I-shaped positioning block 9 tightly engages with the positioning groove 7, firmly splicing the first insulation cover 1 and the second insulation cover 2 together. At the same time, the card seat 13 on the first snap-fit ​​plate 3 moves with the snap-fit ​​plate, and the fixed seat 16 on the second snap-fit ​​plate 4 moves closer. When the positioning block 9 is fully inserted into the positioning groove 7, the elastic plate 18 on the fixed seat 16 drives the card plate 17 to spring into the slot 14 of the card seat 13, completing the locking. At this time, the insulation cover forms a complete closed structure, realizing comprehensive insulation of the equipment.

[0026] When maintenance or repair of the heat exchanger is required, simply press the retaining plate 17 by hand. The retaining plate 17 compresses the elastic plate 18 and retracts into the fixed seat 16, separating from the latch 14 of the retaining seat 13, thus releasing the locking state. At this time, the spring 10 stretched between the two sets of connecting plates 11 releases its elasticity, pushing the first retaining plate 3 and the second retaining plate 4 to separate from each other along the sliding groove 6. The positioning block 9 disengages from the positioning groove 7, and the first insulation cover 1 and the second insulation cover 2 can be easily separated and removed from the equipment.

[0027] The entire installation and disassembly process requires no tools and can be completed manually. The operation steps are simple and intuitive, allowing even those unfamiliar with the equipment to quickly master the process. This quick-release design significantly reduces the installation and disassembly time of the insulation cover, making it particularly suitable for equipment requiring frequent maintenance. It ensures excellent insulation performance while improving equipment maintenance efficiency and reducing labor costs.

[0028] The usage method of this embodiment is as follows: The first insulation cover 1 and the second insulation cover 2 are fitted onto the outside of the plate heat exchanger, and the pipes of the plate heat exchanger pass through the through holes on the outside of the first insulation cover 1 and the second insulation cover 2. Subsequently, the first locking plate 3 and the second locking plate 4 are pushed closer and slid together until the positioning block 9 is inserted into the positioning groove 7. At the same time, the elastic plate 18 and the locking plate 17 are also locked into the slot 14 of the fixed seat 16, thereby completing the locking. When disassembly is required, simply press the latch plate 17 to retract it into the fixing seat 16 and disengage it from the latch 14, thus separating the latch plate 17 from the latch 14. Then, under the elastic force of the spring 10, the first latch plate 3 and the second latch plate 4 can be separated from each other.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
