Description

Technical Field

[0001] The invention relates to the technical field of plate heat exchangers, and in particular to a high-stability, impact-resistant, detachable plate heat exchanger and a preparation method thereof. Background Art

[0002] A plate heat exchanger is a device used for heat exchange. It consists of a series of thin metal plates that form multiple channels for transferring two fluids of different temperatures, thereby achieving heat transfer.

[0003] For example, a plate heat exchanger with publication number CN102980328B includes a heat exchange plate forming a first fluid channel and a second fluid channel, wherein the first fluid channel has an upstream portion of the fluid channel and a downstream portion of the fluid channel separated, and the upstream portion of the fluid channel and the downstream portion of the fluid channel are fluidically connected through a fluid connecting device. The plate heat exchanger of the present invention does not rely on a distributor to obtain uniform refrigerant distribution, and based on the relevant heat transfer mechanism of refrigerant evaporation, different heat exchange areas are set in the channel to enhance heat transfer. The distributor-free heat exchanger according to the present invention not only reduces the difficulty in production and processing, but also broadens the practical application scope and conditions of the product. In addition, since there is no distributor in the heat exchanger, the total pressure drop of the refrigerant flow path is lower than that of other products, leaving more room for the selection of the expansion valve;

[0004] Another example is a plate heat exchanger with publication number CN105066751B. The adjacent plates of the plate heat exchanger are provided with a first sealing ring and a second sealing ring. When one side cooperates, the first sealing ring forms a steam cavity, and the second sealing ring forms a seawater cavity. Steam enters the steam cavity through the heat source inlet, and seawater enters the seawater cavity through the seawater inlet. When one side is provided with a third sealing ring and a fourth sealing ring, the third sealing ring forms a seawater evaporation cavity. The device provided by this scheme uses a plate heat exchanger to replace a tube heat exchanger. The two media in the plate heat exchanger flow in reverse, and the heat exchange efficiency is high. It can economically achieve an end temperature difference of about 1°C. At this time, the plate does not need to be very long. Compared with the tube heat exchanger, the volume of the heat exchanger can be effectively reduced, thereby reducing the footprint of the seawater desalination multi-effect evaporation system.

[0005] The plate heat exchanger in the above technical solution improves the heat exchange efficiency of the plate heat exchanger by optimizing the structure of the plate heat exchanger. In actual use, the heat exchange structure of the existing plate heat exchanger has become mature. However, during the use of the plate heat exchanger, the single heat exchange plate inside it is relatively fragile. When a collision occurs during use, it is easy to cause its edge deformation and cause water leakage. In addition, when squeezing multiple layers of heat exchange plates, it is easy to cause uneven squeezing force, resulting in gaps between the heat exchange plates. Summary of the invention

[0018] A method for preparing a high-stability, impact-resistant, detachable plate heat exchanger comprises the following steps;

[0019] S1: First, multiple heat exchange plates are clamped between two clamping rods. At this time, the pressure plate and the fixed plate are brought close to each other, so that the fixed plate and the pressure plate are close to each other to squeeze the two sides of the multiple heat exchange plates, so that the multiple heat exchange plates are in contact with each other to form a whole. At this time, the cold and hot water are sent into the heat exchange plates from the two water inlets located at the upper end of the fixed plate;

[0020] S2: When hot water enters from the inside of the heat exchange plate, the hot water will enter the heat exchange chamber from the water guide port, so that the hot water is evenly spread inside the heat exchange chamber, thereby heating the metal plate as a whole. Since the two adjacent metal plates are distributed in a mirror image, the cold water will enter the adjacent heat exchange chamber from the water guide port, so that the cold water is evenly spread inside the heat exchange chamber, and the heat in the hot water is transferred to the cold water, achieving the effect of heating the cold water and cooling the hot water. The water circulated inside the heat exchange plate will be discharged through the water inlet at the lower end of the fixed plate;

[0021] S3: When the pressure plate and the fixed plate are away from each other, since the heat exchange plate has good elasticity, the heat exchange plate is bent to separate the card slot and the card slot rod from each other, thereby realizing the installation and removal of the heat exchange plate. At the same time, when the pressure plate and the heat exchange plate are away from each other, the protective ring can move inside the four positioning rods, and the position of the protective ring is adjusted until the protective ring cannot interfere with the installation and removal of the heat exchange plate. When the pressure plate and the fixed plate are close to each other until multiple heat exchange plates form a whole, the card slot and the card slot inside another protective frame are card slotted with each other, so that multiple protective rings form a whole. At this time, the whole formed by the protective ring is located on the outside of the heat exchange plate. At the same time, the two sides of the whole formed by the protective ring are respectively carded with the inside of the first positioning groove and the second positioning groove, so that the outside of the heat exchange plate is wrapped and protected when the heat exchange plate is working;

[0022] S4: When the pressure plate moves, the pressure plate will drive the synchronous shaft to move inside the positioning rod. Since the gear at the end of the synchronous shaft is meshed with the rack inside the positioning rod, the synchronous shaft will rotate inside the positioning rod. When the synchronous shaft rotates, the synchronous shaft drives the linkage shaft to rotate through the bevel gear, and the linkage shaft drives the connecting shaft to rotate through the bevel gear. The two synchronous shafts are connected to each other through the linkage shaft to achieve synchronous rotation, and the two linkage shafts are connected through the connecting shaft to achieve synchronous rotation, so that each synchronous shaft rotates synchronously, so that during the movement of the pressure plate, its four corners are connected to the synchronous shaft to form a synchronous movement, and the gear at the end of the synchronous shaft and the rack inside the positioning rod are connected to form a movement, so that the position of the internal positioning hole of the pressure plate on the outside of the four synchronous shafts is always consistent, and the synchronous shaft is driven to rotate by turning the rotating handle to adjust the position of the pressure plate inside the positioning rod;

[0023] S5: When the pressure plate and the fixed plate are close to each other until the multiple heat exchange plates form a whole, the positioning bolts are installed in the mounting grooves on both sides of the fixed plate and the pressure plate, thereby applying a force to the fixed plate and the pressure plate to move closer to each other, so that the heat exchange plates between the fixed plate and the pressure plate are connected more tightly.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The invention discloses a highly stable and impact-resistant detachable plate heat exchanger and a preparation method thereof. When the pressure plate and the fixed plate are close to each other until the multiple heat exchange plates form a whole, the snap-fitting strip is snap-fitted with the snap-fitting strip inside another protective frame, so that the multiple protective rings form a whole. At this time, the whole formed by the protective ring is located outside the heat exchange plate. At the same time, the two sides of the whole formed by the protective ring are snap-fitted with the inside of the first positioning groove and the second positioning groove respectively, so that the outer side of the heat exchange plate is wrapped and protected when the heat exchange plate is working, so as to prevent the heat exchange plate from being deformed by impact during working and causing water leakage;

[0026] Furthermore, when the pressure plate moves, the pressure plate will drive the synchronous shaft to move inside the positioning rod. Since the gear at the end of the synchronous shaft is meshed with the rack inside the positioning rod, the synchronous shaft will rotate inside the positioning rod. When the synchronous shaft rotates, the synchronous shaft drives the linkage shaft to rotate through the bevel gear, and the linkage shaft drives the connecting shaft to rotate through the bevel gear. The two synchronous shafts are connected to each other through the linkage shaft to achieve synchronous rotation, and the two linkage shafts are connected through the connecting shaft to achieve synchronous rotation, so that each synchronous shaft rotates synchronously, so that when the pressure plate moves, it always remains parallel to the fixed plate and perpendicular to the positioning rod, so that the pressure plate applies uniform pressure to the heat exchange plate to prevent the heat exchange plate from being squeezed unevenly and causing gaps;

[0027] Furthermore, during the movement of the pressure plate, its four corners are interconnected with the synchronization shaft to form a synchronous movement, and the gear at the end of the synchronization shaft and the rack on the inner side of the positioning rod are interconnected to form movement, so that the position of the internal positioning hole of the pressure plate on the outside of the four synchronization shafts is always consistent. At the same time, the synchronization shaft is driven to rotate by turning the turning handle to adjust the position of the pressure plate on the inner side of the positioning rod.

Embodiment 2:

[0051] Based on Example 1, its specific working principle is as follows:

[0052] First, multiple heat exchange plates 7 are clamped between two clamping rods 5. At this time, the pressure plate 4 and the fixed plate 1 are brought close to each other, so that the fixed plate 1 and the pressure plate 4 are close to each other to squeeze the two sides of the multiple heat exchange plates 7, so that the multiple heat exchange plates 7 are in contact with each other to form a whole. At this time, the cold and hot water are sent into the heat exchange plates 7 from the two water inlets 19 located at the upper end of the fixed plate 1;

[0053] When hot water enters from the inside of the heat exchange plate 7, the hot water will enter the heat exchange chamber 702 from the water guide port 703, so that the hot water is evenly spread inside the heat exchange chamber 702, thereby heating the metal plate 701 as a whole. Since the two adjacent metal plates 701 are distributed in a mirror image, the cold water will enter the adjacent heat exchange chamber 702 from the water guide port 703, so that the cold water is evenly spread inside the heat exchange chamber 702, and the heat in the hot water is transferred to the cold water, so as to achieve the effect of heating the cold water and cooling the hot water. The water circulated inside the heat exchange plate 7 will be discharged through the water inlet 19 at the lower end of the fixed plate 1.

[0054] When the pressure plate 4 and the fixed plate 1 are away from each other, since the heat exchange plate 7 has good elasticity, the heat exchange plate 7 is bent to separate the slot 705 and the locking rod 5 from each other, thereby realizing the installation and removal of the heat exchange plate 7. At the same time, when the pressure plate 4 and the heat exchange plate 7 are away from each other, the protective ring 6 can move inside the four positioning rods 3, and the position of the protective ring 6 is adjusted until the protective ring 6 cannot interfere with the installation and removal of the heat exchange plate 7. When the pressure plate 4 and the fixed plate 1 are close to each other until a plurality of heat exchange plates 7 form a whole, the locking strip 602 is locked with the locking strip 602 inside another protective frame 601, so that the plurality of protective rings 6 form a whole. At this time, the whole formed by the protective ring 6 is located on the outside of the heat exchange plate 7. At the same time, the two sides of the whole formed by the protective ring 6 are respectively locked with the inside of the first positioning groove 11 and the second positioning groove 21, so that the outside of the heat exchange plate 7 is wrapped and protected when the heat exchange plate 7 is working.

[0055] When the pressure plate 4 moves, the pressure plate 4 will drive the synchronous shaft 13 to move inside the positioning rod 3. Since the gear at the end of the synchronous shaft 13 is meshed with the rack inside the positioning rod 3, the synchronous shaft 13 will rotate inside the positioning rod 3. When the synchronous shaft 13 rotates, the synchronous shaft 13 drives the linkage shaft 15 to rotate through the bevel gear, and the linkage shaft 15 drives the connecting shaft 16 to rotate through the bevel gear. The two synchronous shafts 13 are connected to each other through the linkage shaft 15 to achieve synchronous rotation, and the two linkage shafts 15 are connected to each other through the connecting shaft 16 to achieve synchronous rotation, so that each synchronous shaft 13 rotates synchronously, so that during the movement of the pressure plate 4, its four corners are connected to the synchronous shaft 13 to form a synchronous movement, and the gear at the end of the synchronous shaft 13 and the rack inside the positioning rod 3 are connected to form a movement, so that the position of the internal positioning hole 8 of the pressure plate 4 on the outside of the four synchronous shafts 13 is always consistent. At the same time, the synchronous shaft 13 is driven to rotate by turning the rotating handle 14 to adjust the position of the pressure plate 4 inside the positioning rod 3;

[0056] When the pressure plate 4 and the fixed plate 1 are close to each other until the multiple heat exchange plates 7 form a whole, the positioning bolts 18 are installed in the mounting grooves 17 on both sides of the fixed plate 1 and the pressure plate 4, thereby applying a force to the fixed plate 1 and the pressure plate 4 to move closer to each other, so that the heat exchange plates 7 between the fixed plate 1 and the pressure plate 4 are connected more tightly.

7. The method for preparing a high-stability, impact-resistant, detachable plate heat exchanger according to claim 3, characterized in that: The steps include: S1: First, a plurality of heat exchange plates (7) are engaged between two engaging rods (5), and at this time, the pressure plate (4) and the fixed plate (1) are brought close to each other, so that the fixed plate (1) and the pressure plate (4) are brought close to each other to squeeze the two sides of the plurality of heat exchange plates (7), so that the plurality of heat exchange plates (7) are in contact with each other to form a whole, and at this time, cold and hot water are sent into the interior of the heat exchange plates (7) from the two water inlets (19) located at the upper end of the fixed plate (1); S2: When hot water enters from the inside of the heat exchange plate (7), the hot water will enter the inside of the heat exchange chamber (702) from the water guide port (703), so that the hot water is evenly spread inside the heat exchange chamber (702), thereby heating the metal plate (701) as a whole. Since the two adjacent metal plates (701) are distributed in a mirror image, the cold water will enter from the water guide port (703) into the adjacent heat exchange chamber (702), so that the cold water is evenly spread inside the heat exchange chamber (702), and the heat in the hot water is transferred to the cold water, thereby achieving the effect of heating the cold water and cooling the hot water. After circulating inside the heat exchange plate (7), the water will be discharged through the water inlet (19) at the lower end of the fixed plate (1); S3: When the pressure plate (4) and the fixed plate (1) are away from each other, since the heat exchange plate (7) has good elasticity, the heat exchange plate (7) is bent to separate the clamping groove (705) and the clamping rod (5) from each other, thereby realizing the installation and removal of the heat exchange plate (7). At the same time, when the pressure plate (4) and the heat exchange plate (7) are away from each other, the protective ring (6) can move inside the four positioning rods (3), and the position of the protective ring (6) is adjusted until the protective ring (6) cannot interfere with the installation and removal of the heat exchange plate (7). When the plurality of heat exchange plates (7) are brought closer to each other and the fixing plate (1) and the fixing plate (1) until the plurality of heat exchange plates (7) form a whole, the snap-fitting strip (602) and the snap-fitting strip (602) inside another protective frame (601) are snap-fitted to each other, so that the plurality of protective rings (6) form a whole. At this time, the whole formed by the protective rings (6) is located outside the heat exchange plates (7), and at the same time, both sides of the whole formed by the protective rings (6) are snap-fitted to the inside of the first positioning groove (11) and the second positioning groove (21), respectively, so that the outside of the heat exchange plates (7) are wrapped and protected when the heat exchange plates (7) are working; S4: When the pressure plate (4) moves, the pressure plate (4) will drive the synchronous shaft (13) to move inside the positioning rod (3). Since the gear at the end of the synchronous shaft (13) and the rack inside the positioning rod (3) are meshed with each other, the synchronous shaft (13) will rotate inside the positioning rod (3). When the synchronous shaft (13) rotates, the synchronous shaft (13) drives the linkage shaft (15) to rotate through the bevel gear. The linkage shaft (15) drives the connecting shaft (16) to rotate through the bevel gear. The two synchronous shafts (13) are connected to each other through the linkage shaft (15) to achieve synchronous rotation. The synchronous rotation is achieved by connection through the connecting shaft (16), and then each synchronous shaft (13) is synchronously rotated, so that during the movement of the pressure plate (4), its four corners are connected to the synchronous shaft (13) to form a synchronous movement, and the gear at the end of the synchronous shaft (13) and the rack inside the positioning rod (3) are connected to each other to form a movement, so that the position of the internal positioning hole (8) of the pressure plate (4) on the outside of the four synchronous shafts (13) is always consistent, and at the same time, the synchronous shaft (13) is driven to rotate by turning the rotating handle (14), so that the position of the pressure plate (4) inside the positioning rod (3) is adjusted; S5: When the pressure plate (4) and the fixed plate (1) are brought closer to each other until the plurality of heat exchange plates (7) form a whole, positioning bolts (18) are installed in the mounting grooves (17) on both sides of the fixed plate (1) and the pressure plate (4), thereby applying a force to bring the fixed plate (1) and the pressure plate (4) closer to each other, so that the heat exchange plates (7) between the fixed plate (1) and the pressure plate (4) are more tightly connected.
