Description

Technical Field

[0001] This utility model relates to the field of evaporator component technology, and in particular to an absorption water source heat pump evaporator structure with replaceable heat exchange components. Background Technology

[0002] In chemical, refrigeration, and food processing industries, evaporators are core equipment for heat exchange, and their operating efficiency directly affects the energy consumption and stability of the production system. Through heat transfer between the refrigerant and the medium, evaporators achieve material evaporation and concentration or low-temperature refrigeration, which is a key link in ensuring continuous production. As industries place increasing demands on energy efficiency and intelligence, the ease of evaporator maintenance has become a focus, especially the replacement efficiency of heat exchange components, which directly affects equipment downtime and production losses. Therefore, developing evaporator structures that facilitate quick replacement of components has significant practical value. Currently, the mainstream methods for fixing evaporator heat exchanger components are bolt fastening or welding connections. Bolt fastening uses multiple sets of bolts and nuts that penetrate the clamping plate and the plates to create axial pressure, ensuring the plates fit tightly and seal, while relying on the positioning grooves on the base plate for limiting. Some large equipment adds spring washers at the bolts to mitigate the impact of vibration on connection stability. Welding connections use high-temperature welding to fix the clamping plate and base plate, and the plates and clamping plate into a whole, utilizing the bonding force of metal molecules to ensure strength. This is suitable for high-pressure and high-viscosity media scenarios. A few evaporators use snap-fit ​​connections, which use the elastic claws on the edge of the plates and the grooves on the base plate for initial fixation, and then use a few bolts to enhance the sealing. However, existing structures present significant inconveniences during maintenance, especially when components need replacement due to scaling, corrosion, or damage, making the process time-consuming and labor-intensive. In bolted structures, plate assemblies are often composed of dozens to hundreds of stacked plates, each requiring multiple sets of bolts for fixation. Disassembly requires loosening each bolt individually, and the bolts are prone to corrosion in humid and hot environments, further increasing the difficulty. While welded structures are robust, replacement requires cutting the weld seams, followed by re-welding and sealing checks, a complex process that may damage surrounding components. Although snap-fit ​​connections are relatively easy to disassemble, the tight fit between the snap-fit ​​and the slot ensures a seal, and repeated disassembly can deform the clips, affecting subsequent installation alignment. These issues make the replacement of heat exchange components cumbersome, significantly extending equipment downtime for maintenance and failing to meet the needs of rapid industrial maintenance. Therefore, a replacement heat exchange component structure for an absorption-type water source heat pump evaporator is proposed to address these problems. Summary of the Invention

[0003] To overcome the above shortcomings, this utility model provides an absorption water source heat pump evaporator structure with replaceable heat exchange components, aiming to improve the problem of scale buildup caused by the inability to replace aging components in a timely manner in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an absorption-type water source heat pump evaporator structure with replaceable heat exchange components, including a clamping plate, a water pipe fixedly connected inside the clamping plate, a bottom plate provided at the bottom of the clamping plate, a sliding mechanism provided inside the bottom plate, and a descaling mechanism provided on the side wall of the clamping plate. The sliding mechanism includes a slider and a connecting rod. The sidewall of the slider is slidably connected to the inside of the base plate, and the sidewall of the connecting rod is fixedly connected to the sidewall of the slider. A connecting block is fixedly connected to the bottom of the clamping plate. A cavity is opened inside the base plate, and a spring is installed inside the base plate. One end of the spring is fixedly connected to the sidewall of the slider, and the other end of the spring is fixedly connected to the bottom of the cavity. A support column is rotatably connected to the sidewall of the base plate, and a torsion block is fixedly connected to the sidewall of the support column.

[0005] As a further description of the above technical solution: The connecting rod sidewall is fixedly connected to the support column sidewall, and the slider sidewall is slidably connected inside the connecting block.

[0006] As a further description of the above technical solution: The connecting rod sidewall is slidably connected inside the cavity, and the connecting block sidewall is slidably connected inside the base plate.

[0007] As a further description of the above technical solution: The descaling mechanism includes a ceramic block and a limiting block. The ceramic block is slidably connected inside the water pipe, and the limiting block is disposed inside the ceramic block. A second cavity is formed inside the ceramic block, and a second spring is disposed inside the second cavity.

[0008] As a further description of the above technical solution: One end of the second spring is fixedly connected to the bottom of the second cavity, and the other end of the second spring is fixedly connected to the bottom of the limiting block.

[0009] As a further description of the above technical solution: The limiting block is slidably connected inside the cavity two, the inner wall of the water pipe has an insertion hole, and the side wall of the water pipe is fixedly connected to a connecting ring.

[0010] As a further description of the above technical solution: A plate is provided between the two clamping plates, and the water pipe passes through the plate and is fixedly connected inside the clamping plate.

[0011] This utility model has the following beneficial effects: 1. In this utility model, when replacing heat exchange components, rotating the torsion block clockwise causes the connecting rod to move along the support column, which in turn causes the slider to slide inward. Under the action of force, the spring contracts inward into the cavity, and after the slider slides out of the connecting block, the clamping plate and the plate slide out from the bottom plate. At this time, the spring and the slider reset, causing the connecting rod and the support column to rotate counterclockwise back, completing the disassembly. This improves the problem of inconvenient replacement of evaporator components and realizes the function of easy disassembly.

[0012] 2. In this utility model, by holding the handle on the ceramic block and sliding the limiting block into the water pipe, the limiting block moves into the cavity two under force, causing the spring two to contract under force. When the limiting block slides into the insertion hole, the spring two returns to its original position, and the ceramic block is fixed inside the water pipe. This improves the problem of scale easily forming in the evaporator water pipe, which affects the heat exchange efficiency, and realizes the function of removing scale. Attached Figure Description

[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] Reference Figures 1-4This utility model provides an embodiment of an absorption-type water source heat pump evaporator structure with replaceable heat exchange components. The structure includes a clamping plate 1 for fixing water pipes 10 and plates 17, forming a stable overall structure to ensure that the components do not easily shift during operation, thus ensuring stable heat exchange. Water pipes 10 are fixedly connected inside the clamping plate 1, transporting the heat exchange medium. Heat transfer is achieved through the flow of the medium, thus achieving the heat exchange effect. A base plate 2 is provided at the bottom of the clamping plate 1, and a sliding mechanism is provided inside the base plate 2 to allow the clamping plate 1 to... The relative sliding between the base plates 2 facilitates the installation, disassembly, and replacement of the clamping plate 1 and related components. A descaling mechanism is provided on the side wall of the clamping plate 1. This mechanism removes scale from the inside of the water pipe 10, preventing scale buildup from affecting heat exchange efficiency. The sliding mechanism includes a slider 5 and a connecting rod 7. The side wall of the slider 5 is slidably connected to the inside of the base plate 2. The slider 5 slides within the base plate 2, and its movement drives the connecting block 3, thereby moving the clamping plate 1. The side wall of the connecting rod 7 is fixedly connected to the side wall of the slider 5. The connecting rod 7 transmits the force of the support column 8 to the slider 5, allowing the rotation of the support column 8 to be converted into the force of the slider 5. Sliding; A connecting block 3 is fixedly connected to the bottom of the clamping plate 1. The connecting block 3 connects the clamping plate 1 and the slider 5, so that the sliding of the slider 5 can drive the clamping plate 1 to move together, thereby realizing the relative position adjustment between the clamping plate 1 and the base plate 2. A cavity 4 is opened inside the base plate 2, and a spring 6 is installed inside the base plate 2. One end of the spring 6 is fixedly connected to the side wall of the slider 5, and the other end of the spring 6 is fixedly connected to the bottom of the cavity 4. The spring 6 is used to provide elastic restoring force for the slider 5. When the slider 5 slides under the action of external force, it can return to the initial position under the elastic force of the spring 6. A support column 8 is rotatably connected to the side wall of the base plate 2. A torsion block 9 is fixedly connected to the side wall of the support column 8. The torsion block 9 is used to facilitate the operator to rotate the support column 8. By twisting the torsion block 9, the support column 8 is driven to rotate, thereby driving the sliding mechanism to work. The side wall of the connecting rod 7 is slidably connected to the inside of the cavity 4, and the side wall of the connecting block 3 is slidably connected to the inside of the base plate 2. The side wall of the connecting rod 7 is fixedly connected to the side wall of the support column 8, and the side wall of the slider 5 is slidably connected to the inside of the connecting block 3. The slider 5 cooperates with the connecting block 3 to slide together. When the slider 5 slides into the inside of the connecting block 3, it can fix the connecting block 3 and the slider 5 together, thereby realizing the connection and fixation between the clamping plate 1 and the base plate 2, achieving a stable connection effect.

[0017] Reference Figures 3-5The descaling mechanism includes a ceramic block 12 and a limiting block 15. The ceramic block 12 is slidably connected inside the water pipe 10. The ceramic block 12 is made of ceramic, which has the characteristics of high hardness and good wear resistance. Its function is to scrape off the dirt on the pipe wall when sliding inside the water pipe 10, and it is not easily worn, ensuring the durability of the descaling effect. The limiting block 15 is set inside the ceramic block 12. The limiting block 15 is used to limit the sliding position of the ceramic block 12 inside the water pipe 10, preventing the ceramic block 12 from sliding out of the water pipe 10. At the same time, it enhances the fit between the ceramic block 12 and the inner wall of the water pipe 10 to a certain extent, improving the descaling effect. A cavity 13 is opened inside the ceramic block 12, and a spring 14 is installed inside the cavity 13. One end of the spring 14 is fixedly connected to the bottom of the cavity 13, and the other end of the spring 14 is fixedly connected to the bottom of the limiting block 15. The limiting block 15 is used to provide elastic force, so that the limiting block 15 can fit tightly against the inner wall of the water pipe 10. When the ceramic block 12 slides, it ensures that the limiting block 15 can always be in contact with the pipe wall, thereby ensuring the limiting effect and the descaling auxiliary effect. The limiting block 15 is slidably connected inside the cavity 13. The inner wall of the water pipe 10 is provided with an insertion hole 11, and a connecting ring 16 is fixedly connected to the side wall of the water pipe 10. The connecting ring 16 is used to connect adjacent water pipes 10 or other pipes to ensure the smooth flow of the medium in the pipe and avoid leakage. A plate 17 is provided between the two clamping plates 1. The water pipe 10 passes through the plate 17 and is fixedly connected inside the clamping plate 1. The water pipe 10 works with the plate 17 to exchange heat. The medium in the water pipe 10 transfers heat to the plate 17 through the pipe wall, and the plate 17 then transfers heat to the surrounding medium, achieving a high-efficiency heat exchange effect.

[0018] Working principle: When using this device, firstly, the evaporator body is fixed inside the heat pump. Then, by holding the handle on the ceramic block 12, the limiting block 15 is slid into the water pipe 10, so that the limiting block 15 is forced to move into the cavity 13, thereby causing the spring 14 to contract. When the limiting block 15 slides into the socket 11, the spring 14 returns to its original position, so that the ceramic block 12 is fixed inside the water pipe 10, thereby achieving the effect of descaling. Next, connect the connecting ring 16 to the pipe with bolts. When water enters the plate 17, it will flow in the material flow channel separated by the plate 17. At the same time, steam is formed in the adjacent heating flow channel, which transfers heat through the metal plate 17 and is discharged from the outlet. When replacing the heat exchange accessories, the connecting rod 7 moves along the support column 8 by turning the torsion block 9 clockwise, thereby driving the slider 5 to slide inward. Under the action of force, the spring-6 contracts into the cavity-4, and the slider 5 slides out of the connecting block 3, and the clamping plate 1 and the plate 17 slide out of the bottom plate 2. At this time, the spring-6 and the slider 5 reset, driving the connecting rod 7 and the support column 8 to rotate back counterclockwise, thereby completing the disassembly and replacement of the heat exchange accessories.
