Description

Technical Field

[0001] The invention belongs to the field of heat exchangers, in particular to a plate heat exchanger which is easy to position and install. Background Art

[0002] A plate heat exchanger is a highly efficient heat exchanger composed of a series of stacked, corrugated metal sheets. Heat is exchanged through thin, rectangular channels formed between the plates. It offers high heat transfer efficiency, minimal heat loss, a compact and lightweight structure, a small footprint, wide applications, and a long service life.

[0003] Since the plate-shaped heat exchange parts inside the traditional plate heat exchanger are in constant contact with the liquid, after a period of use, the device needs to be disassembled and the internal heat exchange parts need to be cleaned.

[0004] However, traditional plate heat exchangers have a large number of heat exchange parts. During the installation process after disassembly, the plate heat exchange parts need to be accurately placed back to their original positions, which is particularly time-consuming and has the risk of installation errors.

[0005] To this end, the present invention provides a plate heat exchanger that is easy to position and install. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: a plate heat exchanger that is easy to position and install according to the present invention includes a transmission plate and a rear pressure plate, the transmission plate and the rear pressure plate are arranged in parallel, a plurality of heat exchange plates arranged at equal intervals are arranged between the transmission plate and the rear pressure plate, two cooling valve pipes and two liquid infusion valve pipes are installed at the front end of the transmission plate, an upper movable rail and a lower movable rail are arranged between the rear pressure plate and the transmission plate, a plurality of screws are arranged on the outer side between the rear pressure plate and the transmission plate, nuts are threadedly connected to the outer sides of the screws, and a central column is provided through the middle of the transmission plate and the rear pressure plate;

[0008] Through the setting of the central column, the transmission plate and the rear pressure plate press multiple heat exchange plates in the middle, and the liquid to be cooled is input from one of the infusion valve tubes. The liquid will be discharged from the other infusion valve tube after passing through half of the heat exchange plates. At the same time, cooling water is input from one of the cooling valve tubes, and the cooling water will be discharged from the other cooling valve tube after passing through the other half of the heat exchange plates. Since multiple heat exchange plates are tightly fitted to each other, the cooling water exchanges the heat of the liquid, thereby achieving a heat exchange effect. When disassembling, unscrew the multiple nuts outward and Remove the rear pressure plate and disassemble multiple heat exchange plates for cleaning. After cleaning, put the middle part of the heat exchange plate on the central column. After all the putting is completed, use the upper and lower movable rails to limit and fix all the heat exchange plates. Finally, fix the rear pressure plate with screws and nuts to press and fix multiple heat exchange plates to complete the installation process. This setting greatly saves the time required for positioning and installation compared to the traditional method of manually placing multiple heat exchange plates one by one, and the space in the middle does not take up too much heat exchange space.

[0009] Preferably, the surface of the heat exchange plate is provided with two circulation holes that are compatible with the cooling valve tube, and the surface of the heat exchange plate is further provided with two closed holes that are compatible with the infusion valve tube. The middle of the heat exchange plate is provided with a through hole that is compatible with the central column. The through hole, closed hole, circulation hole and the edge of the heat exchange plate are all fitted with an elastic sealing strip. The sealing strip isolates the two circulation holes and the two closed holes. The arrangement of the heat exchange plate is as follows: the adjacent heat exchange plates need to be turned up and down. Under the setting of the sealing strip, the cooling valve tube and the infusion valve tube will enter different cavities. The cavity is the space formed by the sealing strip between adjacent heat exchange plates. Heat exchange is carried out by heat conduction through the main body of the heat exchange plate. The positions of the through holes do not pass liquid and do not occupy a large heat exchange space. It also facilitates the positioning and installation process of multiple heat exchange plates.

[0010] Preferably, the top and bottom of the heat exchange plate are provided with docking sockets, the material of the top and bottom of the heat exchange plate are different, and the top mass of the heat exchange plate is greater than the bottom mass. In order to facilitate the positioning and installation process of the heat exchange plate, after all the heat exchange plates are put on the center column, the upper movable rail and the lower movable rail are first moved away from the heat exchange plate, and the heat exchange plate is slightly shaken and vibrated. Due to the different masses of the top and bottom of the heat exchange plate, all the heat exchange plates will become the same direction under the action of gravity. At this time, the heat exchange plate is rotated 180 degrees for each heat exchange plate. After all are adjusted, the upper movable rail and the lower movable rail are closed to fix the heat exchange plate, and finally the rear pressing plate is used to press all the heat exchange plates to complete the installation process. This installation method not only saves time, but also all the heat exchange plates are in the same state at the beginning. There is no need to confirm the heat exchange plates in the initial state one by one. It is only necessary to adjust the heat exchange plates at intervals, which reduces observation time and reduces the problem of installation errors.

[0011] The top of the movable frame is fixed with the top of the movable frame, and the bottom of the movable frame is screwed to the upper and lower guide rails, and the movable frame can be adjusted by adjusting the screw thread.

[0012] The cam is provided with a plurality of guide wheels, and the guide wheels are connected to the front of the center column to form a circle around the center column, so that the guide wheels can rotate and move relative to each other. The other heat exchange plates are blocked on the side, and the power device drives the control disk and the center column to rotate, and then drives the unblocked heat exchange plates to rotate. The other heat exchange plates slide relative to the center column and remain in place. After rotating 180 degrees, the first heat exchange plate is in the opposite direction of the heat exchange plate behind it. Then the blocking assembly moves backward, releasing the next heat exchange plate, and allowing the center column to rotate again. At this time, the unblocked heat exchange plates will rotate together, and the second heat exchange plate will be in the opposite direction to the third heat exchange plate. Since the first and second rotate synchronously, the previous state will not change. In this way, after releasing the heat exchange plate and rotating it, it can be ensured that all adjacent heat exchange plates are in opposite directions. It should be noted that the rear pressure plate should slightly press the heat exchange plate at this time, so that the blocking assembly moves an equal distance each time. In this way, the alignment of the heat exchange plates is completed entirely by machinery, which greatly reduces the time consumed in the installation process of the heat exchanger, while ensuring the accuracy of the installation positioning and reducing the problem of installation sequence errors.

[0013] Preferably, the linkage assembly includes a hydraulic valve, a plurality of inner grooves are provided on the outer side of the center column, a top plate is slidably engaged in the inner groove, the inner side of the center column is hollow, and the inner side of the center column is connected to the hydraulic valve. By filling liquid into the hydraulic valve, the plurality of top plates are pushed outward, thereby fixing the plurality of heat exchange plates under the action of friction. After releasing the hydraulic pressure inside the hydraulic valve and the center column, the heat exchange plates become loose and can be easily removed.

[0014] Preferably, the blocking assembly includes two side pressure plates, and the front ends of the transmission plate and the rear pressure plate are each provided with two symmetrically arranged adjustment grooves, in which the side pressure plates are slidably connected, and the rear end of the rear pressure plate is provided with a power assembly for controlling the movement of the side pressure plates. The power assembly drives the two side pressure plates to move synchronously, and the moving distance is the thickness of a heat exchange plate, so that only one heat exchange plate is added each time.

[0015] Preferably, the power assembly includes two servo motors, and a transmission wheel that fits the surface of the side pressure plate is provided on one side of the servo motor. A belt is connected between the output end of the servo motor and the transmission wheel. The servo motor drives the transmission wheel to rotate through the belt. The transmission wheel rubs the side pressure plate to adjust the length of the side pressure plate blocking the heat exchange plate. At the same time, the servo motor can be removed after use, and the heat exchanger does not need the participation of the servo motor. At the same time, a series plate is fixed between the rear ends of the two side pressure plates, so that the two side pressure plates can move synchronously, so that the side pressure plates can be removed after all heat exchange plates are adjusted.

[0016] Preferably, a guide wheel is installed above the rear pressure plate, and the bottom of the guide wheel is in contact with the upper movable rail. The setting of the guide wheel facilitates the sliding process of the rear pressure plate and reduces the resistance generated during the movement.

[0017] Preferably, the length of the upper movable rail is the same as the length of the lower movable rail and the center column. The rear end of the upper movable rail is rotatably connected to a deflection arm. When removing or installing the heat exchange plate, the rear pressure plate is moved onto the deflection arm, and the deflection arm and the rear pressure plate are flipped as a whole to expose the center column, which can receive the traction equipment. In this way, the heat exchange plate can be removed or installed at will.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The plate heat exchanger of the present invention is easy to position and install. Through the setting of the central column, the transmission plate and the rear pressure plate press the multiple heat exchange plates in the middle. The liquid to be cooled is input from one of the infusion valve tubes. The liquid will be discharged from the other infusion valve tube after passing through half of the heat exchange plates. At the same time, cooling water is input from one of the cooling valve tubes. The cooling water will be discharged from the other cooling valve tube after passing through the other half of the heat exchange plates. Since the multiple heat exchange plates are tightly fitted to each other, the cooling water exchanges the heat of the liquid, thereby achieving a heat exchange effect. When disassembling, the multiple The nuts are screwed outward to unscrew them, and the rear pressure plate is removed. The multiple heat exchange plates are disassembled for cleaning. After cleaning, the middle part of the heat exchange plate is sleeved on the central column. After all the sleeves are completed, all the heat exchange plates are limited and fixed using the upper and lower movable rails. Finally, the rear pressure plate is fixed with the screws and nuts to press and fix the multiple heat exchange plates to complete the installation process. This setting greatly saves the time required for positioning and installation compared to the traditional method of manually placing multiple heat exchange plates one by one, and the space in the middle does not take up too much heat exchange space.

[0020] 2. The plate heat exchanger described in the present invention is easy to position and install. In order to facilitate the positioning and installation process of the heat exchange plates, after all the heat exchange plates are put on the center column, the upper movable rail and the lower movable rail are first moved away from the heat exchange plates, and the heat exchange plates are slightly shaken and vibrated. Since the masses of the top and bottom of the heat exchange plates are different, under the action of gravity, all the heat exchange plates will change to the same orientation. At this time, the heat exchange plates are rotated 180 degrees for each heat exchange plate. After all adjustments are made, the upper movable rail and the lower movable rail are closed to fix the heat exchange plates. Finally, the rear pressing plate is used to press all the heat exchange plates to complete the installation process. This installation method not only saves time, but also all the heat exchange plates are in the same state at the beginning. There is no need to confirm the initial state of the heat exchange plates one by one. It is only necessary to adjust the heat exchange plates at intervals, which reduces observation time and reduces the problem of installation errors. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] like Figures 1 to 4 As shown, a plate heat exchanger that is easy to position and install according to an embodiment of the present invention includes a transmission plate 2 and a rear pressure plate 1. The transmission plate 2 and the rear pressure plate 1 are arranged in parallel. A plurality of equidistantly arranged heat exchange plates 12 are arranged between the transmission plate 2 and the rear pressure plate 1. Two cooling valve tubes 9 and two liquid infusion valve tubes 10 are installed at the front end of the transmission plate 2. An upper movable rail 4 and a lower movable rail 11 are provided between the rear pressure plate 1 and the transmission plate 2. A plurality of screws 3 are provided on the outer side between the rear pressure plate 1 and the transmission plate 2. The outer side of the screw 3 is threadedly connected with a nut. A central column 13 is provided through the middle of the transmission plate 2 and the rear pressure plate 1.

[0031] During operation, traditional plate heat exchangers have internal plate-shaped heat exchange components that are in constant contact with the liquid. Therefore, after a period of use, the device needs to be disassembled and the internal heat exchange components cleaned. However, traditional plate heat exchangers have a large number of heat exchange components. During the installation process after disassembly, the plate-shaped heat exchange components need to be accurately placed back to their original positions, which is particularly time-consuming and has the risk of installation errors.

[0032] Through the setting of the central column 13, the transmission plate 2 and the rear pressure plate 1 press the multiple heat exchange plates 12 in the middle, and the liquid to be cooled is input from one of the infusion valve tubes 10. The liquid will be discharged from the other infusion valve tube 10 after passing through half of the heat exchange plates 12. At the same time, cooling water is input from one of the cooling valve tubes 9. The cooling water will be discharged from the other cooling valve tube 9 after passing through the other half of the heat exchange plates 12. Since the multiple heat exchange plates 12 are tightly fitted to each other, the cooling water exchanges the heat of the liquid, thereby achieving a heat exchange effect. When disassembling, unscrew the multiple nuts outward and Remove the rear pressure plate 1 and disassemble the multiple heat exchange plates 12 for cleaning. After cleaning, the middle part of the heat exchange plate 12 is sleeved on the central column 13. After all the sleeves are completed, use the upper movable rail 4 and the lower movable rail 11 to limit and fix all the heat exchange plates 12. Finally, fix the rear pressure plate 1 with the screw 3 and the nut to press and fix the multiple heat exchange plates 12 to complete the installation process. Through this setting, compared with the traditional method of manually placing multiple heat exchange plates 12 one by one, the time required for positioning and installation is greatly saved, and the space in the middle does not take up too much heat exchange space.

[0033] like Figures 1 to 4 As shown, the surface of the heat exchange plate 12 is provided with two circulation holes 17 adapted to the cooling valve tube 9, and the surface of the heat exchange plate 12 is also provided with two closed holes 18 adapted to the infusion valve tube 10. The middle portion of the heat exchange plate 12 is provided with a through hole 20 adapted to the central column 13. The through hole 20, the closed hole 18, the circulation hole 17 and the edge of the heat exchange plate 12 are all fitted with an elastic sealing strip 19, which isolates the two circulation holes 17 from the two closed holes 18.

[0034] During operation, the arrangement of the heat exchange plates 12 is as follows: the adjacent heat exchange plates 12 need to be turned up and down. Under the setting of the sealing strip 19, the cooling valve tube 9 and the infusion valve tube 10 will enter different cavities. The cavity is the space formed by the sealing strip 19 between the adjacent heat exchange plates 12. Heat exchange is carried out through the main body of the heat exchange plate 12 for heat conduction. The positions of the perforations 20 do not pass through liquid, and do not occupy a large heat exchange space. It also facilitates the positioning and installation process of multiple heat exchange plates 12.

[0035] like Figures 1 to 4 As shown, the top and bottom of the heat exchange plate 12 are both provided with docking bayonets 16. The material of the top and bottom of the heat exchange plate 12 are different. The mass of the top of the heat exchange plate 12 is greater than that of the bottom.

[0036] During operation, in order to facilitate the positioning and installation process of the heat exchange plates 12, after all the heat exchange plates 12 are put on the center column 13, first move the upper movable rail 4 and the lower movable rail 11 away from the heat exchange plates 12, and slightly shake and vibrate the heat exchange plates 12. Since the masses of the top and bottom of the heat exchange plates 12 are different, under the action of gravity, all the heat exchange plates 12 will change to the same direction. At this time, the heat exchange plates 12 are rotated one hundred and eighty degrees for each heat exchange plate 12. After all adjustments are made, the upper movable rail 4 and the lower movable rail 11 are closed and fixed to the heat exchange plates 12. Finally, the rear pressing plate 1 is used to press all the heat exchange plates 12 to complete the installation process. This installation method not only saves time, but also all the heat exchange plates 12 are in the same state at the beginning. There is no need to confirm the initial state of the heat exchange plates 12 one by one. It is only necessary to adjust the heat exchange plates 12 at intervals, which reduces observation time and reduces the problem of installation errors.

[0037] like Figures 1 to 4 As shown, the top of the transmission plate 2 is slidably engaged with a moving seat 5, and the moving seat 5 is fixedly connected to the upper moving rail 4. The rear pressure plate 1 is slidably engaged with the upper moving rail 4. The portion where the rear pressure plate 1 is connected to the upper moving rail 4 can also slide up and down. The bottoms of the transmission plate 2 and the rear pressure plate 1 are both provided with sliding grooves, and both ends of the lower moving rail 11 are slidably engaged with the sliding grooves.

[0038] During operation, in order to adjust the upper moving rail 4 and the lower moving rail 11, the internal rotation of the moving seat 5 is connected with a bolt, the top of the bolt is located at the top of the moving seat 5, and the bottom of the bolt is threadedly connected to the transmission plate 2. The up and down movement of the moving seat 5 can be controlled by adjusting the bolt. The adjustment method of the connection part of the rear pressure plate 1 and the upper moving rail 4 is the same, and the lower moving rail 11 can slide up and down directly, so that the upper moving rail 4 and the lower moving rail 11 can be closed to the center when needed, and the upper moving rail 4 always keeps supporting the rear pressure plate 1, so that the rear pressure plate 1 can slide on the upper moving rail 4.

[0039] like Figures 1 to 6 As shown, a control disk 8 is fixedly connected to one end of the center column 13 close to the transmission plate 2. A center hole 15 is opened at the front end of the transmission plate 2. The control disk 8 is rotatably engaged with the center hole 15. A linkage component is provided on the outer side of the control disk 8. The linkage component is used to drive the heat exchange plate 12 to rotate. A blocking component is provided between the transmission plate 2 and the rear pressure plate 1. The blocking component is used to block part of the heat exchange plate 12 from the side.

[0040] During operation, in order to facilitate the adjustment of the direction of the heat exchange plate 12, after all the heat exchange plates 12 are sleeved on the center column 13, a power device such as a power drill is used to connect with the control panel 8. Grooves are provided around the control panel 8 to facilitate the connection of the transmission equipment. At this time, the diameter of the center column 13 is smaller than the inner diameter of the through-holes 20 of the heat exchange plate 12. Therefore, when the center column 13 rotates, it will transmit a vibration effect to multiple heat exchange plates 12, so that multiple heat exchange plates 12 are unified in direction under the influence of their own center of gravity. Then, a linkage component is used to connect and transmit the center column 13 and all heat exchange plates 12. Then, a blocking component is used to block some heat exchange plates 12 from the side, starting from the direction of the transmission plate 2, leaving only one heat exchange plate 12. The blocking component blocks the other heat exchange plates 12 from the side, and the power device drives the control panel 8 and the center column 13 to rotate, thereby driving the heat exchange plates 12 that are not blocked to rotate, and the other heat exchange plates 12 and the center The column 13 slides relatively and remains in place. After rotating 180 degrees, the first heat exchange plate 12 is facing opposite to the heat exchange plate 12 behind it. Then the blocking assembly moves backward to release the next heat exchange plate 12, and the center column 13 rotates again. The heat exchange plates 12 that are not blocked at this time will rotate together. At this time, the second heat exchange plate 12 will face opposite to the third heat exchange plate 12. Since the first and second rotate synchronously, the previous state will not change. In this way, after releasing the heat exchange plates 12 and rotating them, it can be ensured that all adjacent heat exchange plates 12 face oppositely. It should be noted that at this time, the rear pressure plate 1 should slightly press the heat exchange plate 12 to allow the blocking assembly to move an equal distance each time. In this way, the alignment of the heat exchange plates 12 is completed entirely by machinery, which greatly reduces the time consumed in the heat exchanger installation process, while ensuring the accuracy of the installation positioning and reducing the problem of installation sequence errors.

[0041] like Figures 1 to 6 As shown, the linkage assembly includes a hydraulic valve 24, a plurality of inner grooves are opened on the outer side of the center column 13, a top plate 25 is slidably engaged in the inner groove, and the inner side of the center column 13 is hollow and communicated with the hydraulic valve 24;

[0042] During operation, by filling liquid into the hydraulic valve 24, multiple top plates 25 are pushed outward, thereby fixing multiple heat exchange plates 12 under the action of friction. After releasing the hydraulic pressure inside the hydraulic valve 24 and the center column 13, the heat exchange plates 12 will become loose and can be easily removed.

[0043] like Figures 1 to 6As shown, the blocking assembly includes two side pressure plates 7, and the front ends of the transmission plate 2 and the rear pressure plate 1 are each provided with two symmetrically arranged adjustment grooves 14, and the side pressure plates 7 are slidably connected in the adjustment grooves 14. The rear end of the rear pressure plate 1 is provided with a power assembly for controlling the movement of the side pressure plates 7. When working, the two side pressure plates 7 are driven to move synchronously by the power assembly, and the moving distance is the thickness of a heat exchange plate 12, so that only one heat exchange plate 12 can be added each time.

[0044] like Figures 1 to 6 As shown, the power assembly includes two servo motors 22, one side of the servo motor 22 is provided with a transmission wheel 23 that is in contact with the surface of the side pressure plate 7, and a belt is connected between the output end of the servo motor 22 and the transmission wheel 23;

[0045] During operation, the servo motor 22 drives the transmission wheel 23 to rotate through the belt. The transmission wheel 23 rubs the side pressure plate 7 to adjust the length of the side pressure plate 7 blocking the heat exchange plate 12. At the same time, the servo motor 22 can be removed after use. When the heat exchanger is working, the servo motor 22 is not required. At the same time, a series plate is fixed between the rear ends of the two side pressure plates 7, so that the two side pressure plates 7 can move synchronously. After all the heat exchange plates 12 are adjusted, the side pressure plates 7 are removed.

[0046] like Figures 1 to 6 As shown, a guide wheel 21 is installed above the rear pressure plate 1, and the bottom of the guide wheel 21 is in contact with the upper movable rail 4. When working, the setting of the guide wheel 21 facilitates the sliding process of the rear pressure plate 1 and reduces the resistance generated during the movement.

[0047] like Figures 1 to 6 As shown, the length of the upper movable rail 4 is the same as the length of the lower movable rail 11 and the center column 13. The rear end of the upper movable rail 4 is rotatably connected to the deflection arm 6. During operation, when removing or installing the heat exchange plate 12, the rear pressure plate 1 is moved onto the deflection arm 6, and the deflection arm 6 and the rear pressure plate 1 are flipped as a whole to expose the center column 13, which can receive the traction equipment, so that the heat exchange plate 12 can be removed or installed at will.

[0048] During operation, through the setting of the central column 13, the transmission plate 2 and the rear pressure plate 1 press the multiple heat exchange plates 12 in the middle, and the liquid to be cooled is input from one of the infusion valve tubes 10. The liquid will be discharged from the other infusion valve tube 10 after passing through half of the heat exchange plates 12. At the same time, cooling water is input from one of the cooling valve tubes 9. The cooling water will be discharged from the other cooling valve tube 9 after passing through the other half of the heat exchange plates 12. Since the multiple heat exchange plates 12 are tightly fitted to each other, the cooling water exchanges the heat of the liquid, thereby achieving a heat exchange effect. When disassembling, unscrew the multiple nuts outward. , and remove the rear pressure plate 1, disassemble the multiple heat exchange plates 12 for cleaning. After cleaning, the middle part of the heat exchange plate 12 is sleeved on the central column 13. After all the sleeves are completed, use the upper movable rail 4 and the lower movable rail 11 to limit and fix all the heat exchange plates 12. Finally, fix the rear pressure plate 1 with the screw 3 and the nut to press and fix the multiple heat exchange plates 12 to complete the installation process. Through this setting, compared with the traditional method of manually placing multiple heat exchange plates 12 one by one, the time required for positioning and installation is greatly saved, and the space in the middle does not take up too much heat exchange space;

[0049] Arrangement of the heat exchange plates 12: Adjacent heat exchange plates 12 need to be rotated up and down. Under the setting of the sealing strip 19, the cooling valve tube 9 and the infusion valve tube 10 will enter different cavities. The cavity is the space formed by the sealing strip 19 between adjacent heat exchange plates 12. Heat exchange is carried out through the main body of the heat exchange plate 12 for heat conduction. The positions of the perforations 20 do not pass liquid, do not occupy a large heat exchange space, and also facilitate the positioning and installation process of multiple heat exchange plates 12;

[0050] In order to facilitate the positioning and installation process of the heat exchange plates 12, after all the heat exchange plates 12 are put on the center column 13, the upper movable rail 4 and the lower movable rail 11 are first moved away from the heat exchange plates 12, and the heat exchange plates 12 are slightly shaken and vibrated. Since the masses of the top and bottom of the heat exchange plates 12 are different, all the heat exchange plates 12 will become the same direction under the action of gravity. At this time, the heat exchange plates 12 are rotated 180 degrees for each heat exchange plate 12. After all are adjusted, the upper movable rail 4 and the lower movable rail 11 are closed and fixed to the heat exchange plates 12. Finally, the rear pressing plate 1 is used to press all the heat exchange plates 12 to complete the installation process. This installation method not only saves time, but also all the heat exchange plates 12 are in the same state at the beginning. There is no need to confirm the heat exchange plates 12 in the initial state one by one. It is only necessary to adjust the heat exchange plates 12 at intervals, which reduces observation time and reduces the problem of installation errors.

[0051] In order to adjust the upper moving rail 4 and the lower moving rail 11, the internal rotation clamp of the moving base 5 is connected with a bolt, the top of the bolt is located at the top of the moving base 5, and the bottom of the bolt is threadedly connected to the transmission plate 2. By adjusting the bolt, the up and down movement of the moving base 5 can be controlled. The adjustment method of the connection part of the rear pressure plate 1 and the upper moving rail 4 is the same, and the lower moving rail 11 can directly slide up and down, so that when needed, the upper moving rail 4 and the lower moving rail 11 can be closed to the center, and the upper moving rail 4 always keeps supporting the rear pressure plate 1, so that the rear pressure plate 1 can slide on the upper moving rail 4;

[0052] In order to facilitate the adjustment of the direction of the heat exchange plate 12, after all the heat exchange plates 12 are sleeved on the center column 13, a power device such as a power drill is used to connect with the control panel 8. Grooves are provided around the control panel 8 to facilitate the connection of the transmission equipment. At this time, the diameter of the center column 13 is smaller than the inner diameter of the through-hole 20 of the heat exchange plate 12. Therefore, when the center column 13 rotates, it will transmit a vibration effect to multiple heat exchange plates 12, so that multiple heat exchange plates 12 are unified in direction under the influence of their own center of gravity. Then, a linkage component is used to connect and transmit the center column 13 and all heat exchange plates 12. Then, a blocking component is used to block some heat exchange plates 12 from the side, starting from the direction of the transmission plate 2, leaving only one heat exchange plate 12. The blocking component blocks the other heat exchange plates 12 from the side, and the power device drives the control panel 8 and the center column 13 to rotate, thereby driving the heat exchange plates 12 that are not blocked to rotate, and the other heat exchange plates 12 and the center column 1 3 slides relative to each other and remains in place. After rotating 180 degrees, the first heat exchange plate 12 is now facing oppositely to the heat exchange plate 12 behind it. Then the blocking assembly moves backward to release the next heat exchange plate 12, and the center column 13 rotates again. The heat exchange plates 12 that are not blocked will rotate together. At this time, the second heat exchange plate 12 will face oppositely to the third heat exchange plate 12. Since the first and second heat exchange plates rotate synchronously, the previous state will not be changed. In this way, after releasing the heat exchange plates 12 and rotating them, it can be ensured that all adjacent heat exchange plates 12 face oppositely. It should be noted that at this time, the rear pressure plate 1 should slightly press the heat exchange plate 12 so that the blocking assembly moves an equal distance each time. In this way, the alignment of the heat exchange plates 12 is completed entirely by machinery, which greatly reduces the time consumed in the installation process of the heat exchanger, while ensuring the accuracy of the installation positioning and reducing the problem of incorrect installation sequence.

[0053] By filling the hydraulic valve 24 with liquid, the multiple top plates 25 are pushed outward, thereby fixing the multiple heat exchange plates 12 under the action of friction. After the hydraulic pressure inside the hydraulic valve 24 and the center column 13 is released, the heat exchange plates 12 become loose and can be easily removed.

[0054] The two side pressure plates 7 are driven to move synchronously by the power assembly, and the moving distance is the thickness of one heat exchange plate 12, so that only one heat exchange plate 12 is added each time;

[0055] The servo motor 22 drives the transmission wheel 23 to rotate through the belt, and the transmission wheel 23 rubs the side pressure plate 7 to adjust the length of the side pressure plate 7 blocking the heat exchange plate 12. At the same time, the servo motor 22 can be removed after use. When the heat exchanger is working, the servo motor 22 is not required. At the same time, a series plate is fixed between the rear ends of the two side pressure plates 7, so that the two side pressure plates 7 can move synchronously. After all the heat exchange plates 12 are adjusted, the side pressure plates 7 can be removed.

[0056] The setting of the guide wheel 21 facilitates the sliding process of the rear pressure plate 1 and reduces the resistance generated during the movement;

[0057] When removing or installing the heat exchange plate 12, the rear pressure plate 1 is moved onto the deflection arm 6, and the deflection arm 6 and the rear pressure plate 1 are flipped over as a whole to expose the central column 13, which can be used to receive the traction equipment, so that the heat exchange plate 12 can be removed or installed at will.
