Description

Technical Field

[0001] This invention belongs to the technical field of plate heat exchangers, specifically, it relates to an improved, high-efficiency, and energy-saving plate heat exchanger. Background Technology

[0002] Plate heat exchangers are a type of high-efficiency heat exchange equipment. The heat exchange medium flows between stacked plates, and high-temperature and low-temperature media are flowed alternately to achieve efficient heat exchange. They have the advantages of high heat exchange efficiency, compact structure and small footprint, and can be used in liquid-liquid, liquid-gas and gas-gas heat exchange operations.

[0003] Plate heat exchangers primarily use water as the heat exchange medium. When a large amount of water passes through a plate heat exchanger, the narrow flow channels between the plates and the presence of numerous corrugations designed to enhance heat exchange efficiency make it easy for scale to accumulate in the plate heat exchanger. Furthermore, the heated water is prone to forming scale, which remains in the plate heat exchanger. Scale and dirt significantly increase the thermal resistance of the plates, weakening the heat transfer effect. Moreover, the blockage of the channels also increases the energy consumption of the water pump, resulting in a certain degree of loss in both the heat exchange efficiency and energy consumption of the entire system.

[0004] In existing technologies, the internal cleaning of plate heat exchangers can be carried out using specialized chemical reagents without disassembling the unit, dissolving the dirt inside. However, when the dirt severely clogs the internal flow channels of the plate heat exchanger and chemical cleaning cannot completely remove it, physical cleaning by disassembly is required. During disassembly, multiple plates need to be separated one by one, cleaned with a high-pressure water gun, and then reassembled. The plates are relatively thin and the gaskets are relatively soft. Improper operation during disassembly and reassembly may cause the plates to deform. In addition, the process of disassembling and reassembling each plate is cumbersome, which also makes the disassembly and cleaning efficiency low. Summary of the Invention

[0005] The purpose of this invention is to provide an improved, high-efficiency and energy-saving plate heat exchanger, which solves the technical problems in related technologies where the plates of plate heat exchangers are easily damaged during disassembly and cleaning, and the disassembly process is cumbersome, resulting in low cleaning efficiency.

[0006] An improved, high-efficiency, and energy-saving plate heat exchanger includes a fixed plate and a clamping plate. Multiple plates and sealing rings are alternately arranged between the fixed plate and the clamping plate. A guide rail is provided on the fixed plate, penetrating the clamping plate. When the clamping plate is slid away from the fixed plate, the plates and sealing rings stack near the fixed plate. The guide rail penetrates the plates. The heat exchanger also includes guide posts, guide rods, and a plate-splitting mechanism. The guide posts are connected to both the fixed plate and the clamping plate. Multiple sealing rings are slidably connected to the guide posts. A gap exists between the guide posts and the plates. The guide rods are connected to the plates... On the fixed plate and the pressing plate, a slidable peeling mechanism is connected to the guide rod. When the pressing plate separates from the multiple pressed plates and the sealing ring, the peeling mechanism can separate the plates and the sealing ring that are in contact with each other. At this time, the plates and the sealing ring can be cleaned. The peeling mechanism includes a first elastic lever and a second elastic lever. The first elastic lever and the second elastic lever can contact the plates and the sealing ring respectively and drive them to slide. As the sliding distance between the plates and the sealing ring increases, the plates and the sealing ring can be cleaned.

[0007] The plate and the sealing ring are pressed together by screws between the fixed plate and the pressure plate. After the screws are released, the pressure plate is slid away from the fixed plate on the guide rail, so that there is a gap between the pressure plate and the plate. This area is used to clean the plate and the sealing ring. After the plate and the sealing ring are cleaned, they are slid to a position close to the pressure plate. At this time, the area between the cleaned plate and the uncleaned plate can be used for cleaning.

[0008] A first hanging ear is fixedly connected to the plate, and a second hanging ear is provided on the sealing ring. The sealing ring is provided between two adjacent plates, and the second hanging ear is provided on the side of the plate. The second hanging ear is slidably connected to the guide post. The first hanging ear can contact the first elastic lever, and the second hanging ear can contact the second elastic lever.

[0009] The sheet-peeling mechanism further includes a sliding frame one, a sliding frame two, a drive frame, and a linkage assembly. Sliding frame one is slidably connected to the guide rod, and an elastic lever one is rotatably connected to the side of sliding frame one near the sheet. Sliding frame two is slidably connected to the guide rod, and an elastic lever two is rotatably connected to the side of sliding frame two near the sealing ring. A linkage assembly connects sliding frame one, sliding frame two, and the drive frame. A drive component is provided on the fixed plate, which can drive the drive frame to slide. When the drive frame slides, it can sequentially drive the sliding frame 2 and the sliding frame 1 to slide through the linkage assembly. The linkage assembly includes a first link, a second link, and a slider. The first link is rotatably connected to the sliding frame 1, the second link is rotatably connected to the drive frame, and both the first and second links are rotatably connected to the slider. The slider is slidably connected to the sliding frame 2. When the drive frame moves, it can drive the first and second links to rotate. While the slider slides on the sliding frame 2, it also drives the sliding frame 2 to slide. When the first and second links rotate to their maximum angle, they can no longer rotate and directly drive the sliding frame 1 to slide.

[0010] When the drive frame slides, the linkage assembly can increase the distance between the first sliding frame and the second sliding frame, and cause the first sliding frame and the second sliding frame to slide toward the pressure plate.

[0011] A sliding rubber sleeve is designed between the sliding frame one and the guide rod. The sliding frame one slides on the guide rod through the sliding rubber sleeve. The drive frame can contact the sliding frame one. The sliding rubber sleeve can provide damping for the sliding of the sliding frame one, so that when docking with the plate and the sealing ring, the drive frame can contact the sliding frame one, maintaining a fixed distance between the elastic lever one and the elastic lever two. When driving the plate and the sealing ring to slide, a certain distance is maintained between the plate and the sealing ring, which is convenient for cleaning.

[0012] The first elastic lever and the second elastic lever are rotatably connected to the first sliding frame and the second sliding frame, respectively. When the first elastic lever slides toward the fixed plate and contacts the first hanging ear, it can rotate. When the first elastic lever slides toward the pressure plate and contacts the first hanging ear, it can push the plate to slide. When the second elastic lever slides toward the fixed plate and contacts the second hanging ear, it can rotate. When the second elastic lever slides toward the pressure plate and contacts the second hanging ear, it can push the sealing ring to slide.

[0013] When the drive frame component drives the drive frame to slide toward the fixed plate, the drive frame can come into contact with the sliding frame and push the sliding frame to slide.

[0014] When the first sliding frame contacts the second sliding frame, the distance between the first elastic lever and the second elastic lever is fixed. When the first elastic lever contacts and rotates with the first hanging ear, the second elastic lever contacts and rotates with the second hanging ear. When the first elastic lever moves to the side of the first hanging ear that is close to the fixed plate, the second elastic lever moves to the side of the second hanging ear that is close to the fixed plate.

[0015] When the driving component drives the driving frame to slide toward the pressure plate, the driving frame drives the sliding frame two to slide through the linkage assembly. At this time, the distance between the sliding frame one and the sliding frame two increases. When the distance between the sliding frame two and the sliding frame one remains constant, the sliding frame two drives the sliding frame one to slide through the linkage assembly.

[0016] When the first sliding frame and the second sliding frame slide towards the pressure plate, they respectively push the plate and the sealing ring to slide. There is a gap between the plate and the sealing ring when they slide, which allows for cleaning.

[0017] The significant technical effects of this invention are as follows: 1. By setting up two hanging ears, the positions of the plate and the sealing ring are fixed. After separation, they will slide on the guide rail and guide post. On the one hand, they will not be directly separated for cleaning. On the other hand, fixing the plate and the sealing ring at both ends can enhance their stability during the cleaning process. Compared with the traditional method of disassembling them for cleaning, this application is also easier to restore after cleaning, further improving efficiency. 2. By setting up elastic lever one and elastic lever two, the present invention does not push the plate and sealing ring when sliding towards the fixed plate, but can push the plate and sealing ring when sliding towards the pressing plate. Each time, one plate and sealing ring are pushed to move, and they are separated at the same time, which makes it convenient to clean them in sequence. 3. This invention, by setting elastic lever one and elastic lever two to cooperate with hanging ear one and hanging ear two respectively, separates multiple plates and sealing rings during the reciprocating sliding process. After separation, each plate and sealing ring can be cleaned. During cleaning, the plates and sealing rings remain in a parallel state. After cleaning, they are stacked near the pressing plate, achieving cleaning under fixed conditions, which is less likely to cause damage. At the same time, the relative stacking state remains unchanged, which also facilitates reassembly after cleaning. The positions of the plates and sealing rings correspond, which greatly improves the protection and efficiency of the plates during the cleaning and reassembly process. Attached Figure Description

[0029] like Figure 1-7The diagram illustrates an improved, high-efficiency, and energy-saving plate heat exchanger according to an embodiment of the present invention. It includes a fixed plate 1 and a pressing plate 2. Multiple plates 3 and sealing rings 4 are alternately arranged between the fixed plate 1 and the pressing plate 2. A guide rail 5 penetrates the pressing plate 2 on the fixed plate 1. When the pressing plate 2 is slid away from the fixed plate 1, the plates 3 and sealing rings 4 stack near the fixed plate 1. The guide rail 5 penetrates the plates 3. The device also includes a guide post 6, a guide rod 7, and a plate-splitting mechanism. The guide post 6 is connected to both the fixed plate 1 and the pressing plate 2. Multiple sealing rings 4 are slidably connected to the guide post 6. There is a gap between the guide post 6 and the plates 3. The guide rod 7 is connected to both the fixed plate 1 and the pressing plate 2. A plate-splitting mechanism is slidably connected to the guide rod 7. When the pressing plate 2 separates from the pressed plates 3 and sealing rings 4... The segment peeling mechanism can separate the mating plates 3 and sealing rings 4, allowing for cleaning of both. The segment peeling mechanism includes a first elastic lever 8 and a second elastic lever 9, which respectively contact the plates 3 and sealing rings 4 and drive them to slide. As the sliding distance between the plates 3 and sealing rings increases, the plates 3 and sealing rings 4 can be cleaned. This application sequentially separates the sealing rings 4 from the plates 3, without separating the sealing rings 4 from the overall frame (fixed plate 1, guide column 6, guide rail 5), allowing cleaning in a fixed state. This structure avoids deformation and damage to the plates 3 due to uneven stress or uneven placement after individual disassembly. Furthermore, cleaning without disassembly facilitates reassembly, improving overall cleaning efficiency.

[0030] The fixing plate 1 and the clamping plate 2 are pressed together by screws to clamp the plate 3 and the sealing ring 4. After releasing the screws, the clamping plate 2 is slid away from the fixing plate 1 on the guide rail 5, so that there is a gap between the clamping plate 2 and the plate 3. Figure 1-2 As shown, this area is used to clean the plate 3 and the sealing ring 4. After cleaning, the plate 3 and the sealing ring 4 slide to a position close to the pressure plate 2. At this time, the area between the cleaned plate 3 and the uncleaned plate 3 can be used for cleaning.

[0031] like Figure 3-4 As shown, a first hanging ear 10 is fixedly connected to the plate 3, and a second hanging ear 11 is provided on the sealing ring 4. The sealing ring 4 is located between two adjacent plates 3, and the second hanging ear 11 is located on the side of the plate 3. The second hanging ear 11 is slidably connected to the guide post 6. The first hanging ear 10 can contact the first elastic lever 8, and the second hanging ear 11 can contact the second elastic lever 9. The second hanging ear 11 extends to the outside of the plates 3 that are attached to each other on both sides. The second hanging ear 11 does not participate in sealing the gap between the plates 3.

[0032] The sheet-peeling mechanism also includes a sliding frame 12, a sliding frame 2 13, a drive frame 14, and a linkage assembly. Sliding frame 12 is slidably connected to the guide rod 7, and an elastic lever 8 is rotatably connected to the side of sliding frame 12 near the sheet 3. Sliding frame 2 13 is slidably connected to the guide rod 7, and an elastic lever 9 is rotatably connected to the side of sliding frame 2 13 near the sealing ring 4. A linkage assembly connects sliding frame 12, sliding frame 2 13, and drive frame 14. Figure 1-2 As shown, a driving component 15 is provided on the fixed plate 1. The driving component 15 can drive the driving frame 14 to slide. When the driving frame 14 slides, it can sequentially drive the sliding frame 13 and the sliding frame 12 to slide through the linkage assembly. In this embodiment, the driving component 15 uses screws to drive the driving frame 14 to slide. The two screws on both sides of the fixed plate 1 rotate synchronously through a motor drive, driving the two driving mechanisms to slide synchronously. Figure 5-7 As shown, the linkage assembly includes a first linkage 17, a second linkage 18, and a slider 19. The first linkage 17 is rotatably connected to the first sliding frame 12, and the second linkage 18 is rotatably connected to the drive frame 14. Both the first linkage 17 and the second linkage 18 are rotatably connected to the slider 19, and the slider 19 is slidably connected to the second sliding frame 13. When the drive frame 14 moves, it can drive the first linkage 17 and the second linkage 18 to rotate. While the slider 19 slides on the second sliding frame 13, it also drives the second sliding frame 13 to slide. When the first linkage 17 and the second linkage 18 reach their maximum rotation angle, they cannot rotate and directly drive the first sliding frame 12 to slide.

[0033] When the drive frame 14 slides, the linkage assembly can increase the distance between the sliding frame 12 and the sliding frame 2 13, and drive the sliding frame 12 and the sliding frame 2 13 to slide towards the pressure plate 2. The plate 3 and the sealing ring 4 are pushed and separated. Each time, one plate 3 and the sealing ring 4 are driven and separated, so that each plate 3 and the sealing ring 4 can be cleaned in turn. Maintaining the distance is also to provide operating space.

[0034] A sliding rubber sleeve 16 is designed between the sliding frame 12 and the guide rod 7. The sliding frame 12 slides on the guide rod 7 through the sliding rubber sleeve 16. The drive frame 14 can contact the sliding frame 12. The sliding rubber sleeve 16 can provide damping for the sliding of the sliding frame 12, so that when docking with the plate 3 and the sealing ring 4, the drive frame 14 can contact the sliding frame 12, maintaining a fixed distance between the elastic lever 18 and the elastic lever 29. When driving the plate 3 and the sealing ring 4 to slide, a certain distance is maintained between the plate 3 and the sealing ring 4 for easy cleaning. Through the damping setting, the sliding frame 12 only starts to move after both the drive frame 14 and the sliding frame 2 13 have started to move. When the sliding frame 12 slides, the distance between it and the sliding frame 2 13 or the drive frame 14 is a fixed distance. On the one hand, it ensures the distance between the separated plate 3 and the sealing ring 4, and on the other hand, it ensures simultaneous docking when docking with the lug 10 and the lug 2 11.

[0035] Elastic lever 8 and elastic lever 9 are rotatably connected to sliding frame 12 and sliding frame 23, respectively. When elastic lever 8 slides towards fixed plate 1 and contacts hanging ear 10, it can rotate. When elastic lever 8 slides towards pressure plate 2 and contacts hanging ear 10, it can push plate 3 to slide. When elastic lever 9 slides towards fixed plate 1 and contacts hanging ear 21, it can rotate. When elastic lever 9 slides towards pressure plate 2 and contacts hanging ear 21, it can push sealing ring 4 to slide. Figure 5 As shown, an elastic plate is connected between the elastic lever 8 and the slide frame 12, and an elastic plate is connected between the elastic lever 9 and the slide frame 13. These are used to maintain the rebound ability of the elastic lever 8 and the elastic lever 9 after rotation. The elastic lever 8 and the elastic lever 9 can also be kept to rebound after rotation even when they are inverted, so as to avoid the inability to rebound due to gravity. Springs or other methods can also be used.

[0036] like Figure 3-4 As shown, when the drive frame 14 component drives the drive frame 14 to slide towards the fixed plate 1, the drive frame 14 can contact the sliding frame 12 and push the sliding frame 12 to slide. When the sliding frame 12 contacts the sliding frame 13, the distance between the elastic lever 8 and the elastic lever 9 is fixed. When the elastic lever 8 contacts and rotates with the hanging ear 10, the elastic lever 9 contacts and rotates with the hanging ear 11. When the elastic lever 8 moves to the side of the hanging ear 10 closer to the fixed plate 1, the elastic lever 9 moves to the side of the hanging ear 11 closer to the fixed plate 1. Figure 5-7As shown, the first elastic lever 8 and the second elastic lever 9 are provided with arc-shaped sides, which rotate when in contact with the first hook ear 10 and the second hook ear 11. When the first elastic lever 8 and the second elastic lever 9 move to the side of the first hook ear 10 and the second hook ear 11 close to the fixed plate 1, they remain in an inclined state. The driving component 15 drives the driving frame 14 to slide towards the pressure plate 2. At this time, the first elastic lever 8 and the second elastic lever 9 rotate and extend into the side of the first hook ear 10 and the second hook ear 11, as shown. Figure 6-7 As shown, there is an angle limiting structure at the rotation point of the first elastic lever 8 and the second elastic lever 9 to support the first elastic lever 8 and the second elastic lever 9, allowing them to rotate only within a 90-degree range. At this time, the plate 3 and the sealing ring 4 can be pushed to slide.

[0037] When the drive component 15 drives the drive frame 14 to slide toward the pressure plate 2, the drive frame 14 drives the sliding frame 13 to slide through the linkage assembly. At this time, the distance between the sliding frame 12 and the sliding frame 13 increases. When the distance between the sliding frame 13 and the sliding frame 12 remains constant, the sliding frame 13 drives the sliding frame 12 to slide through the linkage assembly. When the sliding frame 12 and the sliding frame 13 slide toward the pressure plate 2, they respectively push the plate 3 and the sealing ring 4 to slide. There is a gap between the plate 3 and the sealing ring 4 when they slide, which allows for cleaning.

[0038] This embodiment provides an improved, high-efficiency, and energy-saving plate heat exchanger. When cleaning the plates 3 is required, the clamping plate 2 is first separated from the fixed plate 1. The guide column 6, guide rod 7, and screw in the drive component 15 are all slidably connected to the clamping plate 2. After the clamping plate 2 is slid away from the fixed plate 1, the drive component 15 drives the drive frame 14 to reciprocate. The drive frame 14 pushes the sliding frame 12 to slide towards the fixed plate 1. When the elastic lever 8 and elastic lever 9 contact the lug 10 and lug 11 respectively, they rotate. On the other side, the drive frame 14 rotates in the opposite direction, which in turn drives the sliding frame 12 and the sliding frame 2 13 to slide through the connecting rod 17 and the connecting rod 2 18. The sliding frame 2 13 drives the sealing ring 4 and the plate 3 to move after a certain distance. The separated plate 3 and sealing ring 4 can be cleaned. During the cleaning process, the plate 3 is limited by the guide rail 5 and the sealing ring 4 is limited by the guide post 6. Both of them remain stable and are not prone to bending of the plate 3 or damage to the gasket, which further improves the safety and efficiency of cleaning.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

An improved high-efficiency and energy-saving plate heat exchanger according to claim 7, characterized in that, When the first slide frame (12) contacts the second slide frame (13), the distance between the first elastic lever (8) and the second elastic lever (9) is fixed. When the first elastic lever (8) contacts and rotates with the first hanging ear (10), the second elastic lever (9) contacts and rotates with the second hanging ear (11). When the first elastic lever (8) moves to the side of the first hanging ear (10) close to the fixed plate (1), the second elastic lever (9) moves to the side of the second hanging ear (11) close to the fixed plate (1).

9. An improved high-efficiency and energy-saving plate heat exchanger according to claim 6, characterized in that, When the driving component (15) drives the driving frame (14) to slide toward the pressing plate (2), the driving frame (14) drives the sliding frame two (13) to slide through the linkage assembly. At this time, the distance between the sliding frame one (12) and the sliding frame two (13) increases. When the distance between the sliding frame two (13) and the sliding frame one (12) remains constant, the sliding frame two (13) drives the sliding frame one (12) to slide through the linkage assembly.

10. An improved high-efficiency and energy-saving plate heat exchanger according to claim 9, characterized in that, When the first sliding frame (12) and the second sliding frame (13) slide toward the pressure plate (2), they respectively push the plate (3) and the sealing ring (4) to slide. There is a gap between the plate (3) and the sealing ring (4) when they slide, which allows them to be cleaned.
