Description

Technical Field

[0001] This application relates to the field of heat exchanger manufacturing technology, specifically a heat exchanger positioning device and its usage method. Background Technology

[0002] Plate heat exchangers are common heat exchange devices typically used in industrial production processes for heat transfer. They consist of a series of metal plates held together by gaskets and frames, forming a set of parallel fluid channels. When hot and cold fluids flow through opposite sides of the plate heat exchanger, heat exchange occurs at the boundaries between the metal plates. Heat from the hot fluid is transferred to the cold fluid, achieving a balance in heat transfer; therefore, the installation of the metal plates is crucial.

[0003] The current plate heat exchanger installation is all done manually, requiring the cooperation of multiple workers. In order to fix the metal plates between the fixed plates, the grooves on the metal plates are used to cooperate with the fixing rods for positioning. During the installation process, the metal plates need to be slightly bent before being placed between the fixing rods. Then, the elasticity of the metal plates will allow them to return to a straight state, and the fixing rods will be inserted into the grooves. Since there are a large number of metal plates and they are not fixed until all are installed, one person needs to hold down the metal plates while another person installs them, which is quite labor-intensive and resource-intensive.

[0004] Therefore, it is necessary to provide a heat exchanger positioning device to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a heat exchanger positioning device that solves the problem of labor and material costs in installation.

[0007] The technical solution adopted by this application to solve its technical problem is: a heat exchanger positioning device, including a front end plate, a support frame, and a rear end plate; the support frame includes an upper crossbeam and a lower crossbeam; the upper crossbeam and the lower crossbeam are arranged in parallel, the front end plate is fixedly installed at one end of the upper crossbeam and the lower crossbeam, and the rear end plate is located between the upper crossbeam and the lower crossbeam and is slidably connected to the upper crossbeam and the lower crossbeam.

[0008] The upper crossbeam has a vertical moving groove on its inner side and sliding grooves on both sides, with one end of the sliding groove communicating with the vertical moving groove. An upper clamping plate is slidably installed in the vertical moving groove, and sliding keys are provided on both sides of the upper clamping plate. The end of the sliding key away from the upper clamping plate is slidably engaged with the sliding groove. The lower crossbeam has a horizontal moving groove on its inner side, with the long side of the horizontal moving groove parallel to the long side of the lower crossbeam. A lower clamping plate is fixedly installed on the side of the rear end plate near the front end plate, with the long side of the lower clamping plate parallel to the long side of the lower crossbeam. The bottom of the lower clamping plate is located in the horizontal moving groove and is slidably disposed. Multiple heat exchange plates are provided, and the multiple heat exchange plates are vertically placed between the upper and lower clamping plates. The end face of the heat exchange plates is parallel to the end face of the front end plate, and the heat exchange plates are arranged alternately in a positive and negative direction.

[0009] Therefore, before installation, the rear end plate is moved to the end of the horizontal sliding groove away from the front end plate, so that the lower clamping plate and the upper clamping plate are misaligned. At this time, the sliding key is located at the bottom of the sliding groove, and the upper clamping plate is moved down to the lowest point. The worker places the heat exchange plate diagonally between the upper and lower clamping plates. After multiple heat exchange plates are placed, the rear end plate is pushed closer to the front end plate, and the lower clamping plate pushes the heat exchange plate to gradually become vertical. At the same time, the heat exchange plate pushes the upper clamping plate to move up. When the heat exchange plate is vertical, the upper clamping plate is located at the top of the vertical sliding groove, and the sliding key is located at the top of the sliding groove. Thus, the heat exchange plate can be quickly installed by one worker, solving the problem of labor and material consumption in installation.

[0010] Furthermore, multiple slots are respectively provided on the opposite side of the upper and lower plates, and the slots of the upper and lower plates correspond one-to-one; the slots correspond one-to-one with the heat exchange plates, and the heat exchange plates are installed on the upper and lower plates through the slots; thus, the slots can ensure that the heat exchange plates do not wobble when they are aligned, reducing the chance of misalignment.

[0011] Furthermore, the heat exchange plate has a first opening and a second opening on its end face, and the first opening and the second opening are arranged side by side; the first opening is provided in a pair and arranged side by side; the second opening is provided in a pair and arranged side by side.

[0012] A sealing gasket is provided on the front side of the heat exchange plate, and a heat exchange zone is provided inside the sealing gasket. The opening is located inside the sealing gasket and communicates with the heat exchange zone. The opening is located outside the sealing gasket and does not communicate with the heat exchange zone.

[0013] A second sealing gasket is provided on the reverse side of the heat exchange plate, and a second heat exchange zone is provided inside the second sealing gasket; the second opening is located inside the first sealing gasket and communicates with the second heat exchange zone; the first opening is located outside the first sealing gasket and does not communicate with the second heat exchange zone.

[0014] Thus, after the heat exchange plates are arranged alternately in front and back, the sealing gaskets of adjacent heat exchange plates are in contact with each other, so that the entire heat exchange plate group forms a cold and hot staggered arrangement, thereby realizing the heat exchange of the heat exchange plates.

[0015] Furthermore, flow-limiting protrusions are uniformly arranged between heat exchange zone one and heat exchange zone two; thereby, the flow rate of the medium can be slowed down, ensuring the efficiency of heat exchange.

[0016] Furthermore, the support frame also includes a vertical beam, which is fixedly installed on the upper and lower crossbeams at the ends away from the front end plate and located on the side of the rear end plate away from the front end plate. A mounting plate is provided on the side of the vertical beam away from the rear end plate, and a pushing assembly is fixedly installed on the side of the mounting plate away from the vertical beam. The pushing assembly includes four pushing rods arranged diagonally and slidably with the mounting plate. The axis of each pushing rod is parallel to the long side of the lower crossbeam, and one end of each pushing rod is fixedly connected to the rear end plate. Thus, by synchronously moving the pushing rods, the rear end plate will not sway when moving on the lower crossbeam, thereby reducing the impact on the alignment of the heat exchange plate.

[0017] Furthermore, the pushing assembly also includes a first transmission device; one side of the first transmission device is fixedly connected to the mounting plate, and the two ends of the first transmission device are respectively connected to a second transmission device; one side of the second transmission device is fixedly connected to the mounting plate, and the two ends of the second transmission device are respectively connected to a control seat, the control seat corresponds to the push rod one by one, and is slidably sleeved on the corresponding push rod.

[0018] A stepper motor is installed on one side of the first transmission device, and a spur gear is installed inside the control seat. The center of the spur gear is fixedly connected to the corresponding second transmission device. Multiple teeth are axially arranged on one side of the push rod, and the tooth surface of the spur gear meshes with the teeth. Thus, the first and second transmission devices synchronously transmit the power of the stepper motor to the control seat, so that the four push rods move synchronously, thereby realizing the stable movement of the rear end plate.

[0019] Furthermore, the transmission device 1 is internally equipped with a ring gear, and a frame is fixedly installed on the inner side of the ring gear; an intermediate shaft is fixedly installed in the center of the frame; the axis of the intermediate shaft is perpendicular to the end face of the ring gear, and the two ends of the intermediate shaft are located at the two ends of the ring gear, with bevel gears fixedly installed at the ends.

[0020] The stepper motor has an input shaft at its output end. One end of the input shaft is rotatably mounted inside the transmission unit, and a drive wheel is fixedly installed at the end. The teeth of the drive wheel mesh with the ring gear. Thus, the stepper motor drives the ring gear to rotate through the drive wheel, and the ring gear drives the intermediate shaft to rotate through the frame, thereby causing the bevel gears at both ends to rotate synchronously.

[0021] Furthermore, the end of the intermediate shaft furthest from the frame is located inside the transmission device two and is mounted via a bearing; a driven gear disk is rotatably mounted on the inner side of the transmission device two, and the tooth surface of the bevel gear meshes with the driven gear disk; an output shaft is fixedly mounted in the center of the driven gear disk, with both ends of the output shaft passing through the driven gear disk, and the end of the output shaft being fixedly connected to a spur gear in the corresponding control seat; thus, the bevel gear drives the output shaft to rotate through the driven gear disk, thereby causing the spur gear in the control seat to rotate synchronously, thereby realizing the synchronous movement of the push rod.

[0022] Furthermore, a fixing rod is installed between the front end plate and the rear end plate through a clearance fit, and the axis of the fixing rod is not on the same straight line as the push rod; one side of the fixing rod is provided with a thread; therefore, after the heat exchange plate is installed, the front end plate and the rear end plate are fixedly connected by a nut after the fixing rod is installed.

[0023] Furthermore, the end face of the front end plate is provided with a pair of heat medium inlets and outlets, and the end of the heat medium inlets and outlets near the rear end plate is connected to the opening of the adjacent heat exchange plate; the end face of the front end plate is provided with a pair of cold medium inlets and outlets, and the end of the cold medium inlets and outlets near the rear end plate is connected to the opening of the adjacent heat exchange plate; the heat medium inlets and outlets and the cold medium inlets and outlets are arranged symmetrically.

[0024] Furthermore, the method of using the above-mentioned heat exchanger positioning device includes the following steps:

[0025] S1. Start the stepper motor to rotate forward, pushing the component control rear end plate closer to the vertical beam; the rear end plate moves to the end of the transverse groove away from the front end plate, so that the lower clamping plate and the upper clamping plate are misaligned, and then lock and push the component;

[0026] S2. Workers arrange the heat exchange plates alternately, one facing forward and the other backward, and place them diagonally in the slots of the upper and lower clamping plates.

[0027] S3. After all heat exchange plates are placed, start the stepper motor to reverse and push the component to control the rear end plate to move closer to the front end plate; the lower clamping plate pushes the heat exchange plates to gradually become vertical, while the heat exchange plates push the upper clamping plate to move up; when the heat exchange plates are vertical, the upper clamping plate is located at the top of the vertical sliding groove, and the sliding key is located at the top of the sliding groove; then lock and push the component.

[0028] S4. The worker passes one end of the fixing rod through the front plate and the rear plate in sequence, and then fixes it with a nut, thus completing the assembly of the heat exchanger.

[0029] The beneficial effects of this application are as follows: The heat exchanger positioning device provided by this application, by setting an upper clamping plate and a lower clamping plate, before installation, moves the rear end plate to the end of the horizontal sliding groove away from the front end plate, so that the lower clamping plate and the upper clamping plate are misaligned; at this time, the sliding key is located at the bottom of the sliding groove, and the upper clamping plate moves down to the lowest point; the worker places the heat exchange plate obliquely between the upper and lower clamping plates. After multiple heat exchange plates are placed, the rear end plate is pushed closer to the front end plate, the lower clamping plate pushes the heat exchange plate to gradually become vertical, and at the same time the heat exchange plate pushes the upper clamping plate to move up; when the heat exchange plate is in a vertical state, the upper clamping plate is located at the top of the vertical sliding groove, and the sliding key is located at the top of the sliding groove. Thus, the heat exchange plate can be quickly installed by one worker, solving the problem of labor and material consumption in installation.

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0045] like Figures 1-8 As shown, this application provides a heat exchanger positioning device, including a front end plate 1, a support frame 2, and a rear end plate 3; see reference... Figures 1-3 The support frame 2 includes an upper crossbeam 22 and a lower crossbeam 23. The upper crossbeam 22 and the lower crossbeam 23 are arranged in parallel. The front end plate 1 is fixedly installed at one end of the upper crossbeam 22 and the lower crossbeam 23. The rear end plate 3 is located between the upper crossbeam 22 and the lower crossbeam 23 and is slidably connected to the upper crossbeam 22 and the lower crossbeam 23.

[0046] Reference Figure 2 , Figure 3A vertical moving groove 221 is provided on the inner side of the upper crossbeam 22, and sliding grooves 222 are provided on both sides of the upper crossbeam 22. One end of the sliding groove 222 is connected to the vertical moving groove 221. An upper clamping plate 24 is slidably installed in the vertical moving groove 221. Sliding keys 241 are provided on both sides of the upper clamping plate 24. The end of the sliding key 241 away from the upper clamping plate 24 is slidably engaged with the sliding groove 222. A horizontal moving groove 231 is provided on the inner side of the lower crossbeam 23. The long side of the horizontal moving groove 231 is parallel to the long side of the lower crossbeam 23. A lower clamping plate 31 is fixedly installed on the side of the rear end plate 3 near the front end plate 1. The long side of the lower clamping plate 31 is parallel to the long side of the lower crossbeam 23. The bottom of the lower clamping plate 31 is located in the horizontal moving groove 231 and is slidably set. Multiple heat exchange plates 4 are provided. Multiple heat exchange plates 4 are placed vertically between the upper clamping plate 24 and the lower clamping plate 31. The end face of the heat exchange plate 4 is parallel to the front end plate 23. The end faces of the plates 1 are parallel, and the heat exchange plates 4 are arranged alternately, one facing forward and one facing backward. Therefore, before installation, the rear end plate 3 is moved to the end of the horizontal sliding groove 231 away from the front end plate 1, so that the lower clamping plate 31 and the upper clamping plate 24 are misaligned. At this time, the sliding key 241 is located at the bottom of the sliding groove 222, and the upper clamping plate 24 is moved down to the lowest position. The worker places the heat exchange plates 4 diagonally between the upper and lower clamping plates 31. After multiple heat exchange plates 4 are placed, the rear end plate 3 is pushed closer to the front end plate 1, and the lower clamping plate 31 pushes the heat exchange plates 4 to gradually become vertical. At the same time, the heat exchange plates 4 push the upper clamping plate 24 to move upward. When the heat exchange plates 4 are vertical, the upper clamping plate 24 is located at the top of the vertical sliding groove 221, and the sliding key 241 is located at the top of the sliding groove 222. Thus, the heat exchange plates 4 can be quickly installed by one worker, solving the problem of labor and material consumption in installation.

[0047] The upper plate 24 and lower plate 31 each have multiple slots on opposite sides, with each slot corresponding to a different heat exchange plate 4. The upper plate 24 and lower plate 31 are fitted with the heat exchange plate 4 via these slots. This ensures that the heat exchange plate 4 does not wobble when aligned, reducing the chance of misalignment. (Refer to...) Figure 3 When the heat exchange plate 4 is tilted, the central axis of the cross section intersects with the vertical line of the slot of the upper plate 24. When the heat exchange plate is vertical, the central axis of the cross section of the heat exchange plate 4 when it is tilted is on the same straight line as the vertical line of the slot of the upper plate 24.

[0048] Reference Figure 4 The heat exchange plate 4 has a first opening 401 and a second opening 402 on its end face. The first opening 401 and the second opening 402 are arranged side by side. There is a pair of first openings 401 arranged side by side. There is a pair of second openings 402 arranged side by side.

[0049] Wherein: A sealing gasket 41 is provided on the front side of the heat exchange plate 4, and a heat exchange zone 1 is provided inside the sealing gasket 41; a through-hole 401 is located inside the sealing gasket 41 and communicates with the heat exchange zone 1; a through-hole 402 is located on the outside of the sealing gasket 41 and does not communicate with the heat exchange zone 1; A sealing gasket 42 is provided on the back side of the heat exchange plate 4, and a heat exchange zone 2 is provided inside the sealing gasket 42; a through-hole 402 is located inside the sealing gasket 41 and communicates with the heat exchange zone 2. The opening 401 is located outside the sealing gasket 41 and is not connected to the heat exchange zone 2. Therefore, after the heat exchange plates 4 are installed alternately in front and back, the sealing gaskets 41 or 42 of two adjacent heat exchange plates 4 are in contact with each other, so that the entire heat exchange plate group 4 forms a cold and hot staggered arrangement, thereby realizing the heat exchange of the heat exchange plates 4. The flow-limiting protrusions 43 are uniformly arranged between the heat exchange zone 1 and the heat exchange zone 2. Therefore, the flow rate of the medium can be slowed down to ensure the efficiency of heat exchange.

[0050] Reference Figure 1 , Figure 5 The support frame 2 also includes a vertical beam 21, which is fixedly installed on the upper crossbeam 22 and the lower crossbeam 23 at the end away from the front end plate 1, and located on the side of the rear end plate 3 away from the front end plate 1. A mounting plate is provided on the side of the vertical beam 21 away from the rear end plate 3, and a pushing assembly 5 is fixedly installed on the side of the mounting plate away from the vertical beam 21. The pushing assembly 5 includes four pushing rods 55, which are arranged diagonally and slidably with the mounting plate. The axis of the pushing rod 55 is parallel to the long side of the lower crossbeam 23, and one end of the pushing rod 55 is fixedly connected to the rear end plate 3. Thus, by moving the pushing rods 55 synchronously, the rear end plate 3 will not swing when moving on the lower crossbeam 23, thereby reducing the impact on the alignment of the heat exchange plate 4.

[0051] Reference Figures 5-8 The pushing component 5 also includes a first transmission device 51; one side of the first transmission device 51 is fixedly connected to the mounting plate, and the two ends of the first transmission device 51 are respectively connected to a second transmission device 53; one side of the second transmission device 53 is fixedly connected to the mounting plate, and the two ends of the second transmission device 53 are respectively connected to a control seat 54, the control seat 54 corresponds to the push rod 55 one by one, and is slidably sleeved on the corresponding push rod 55.

[0052] A stepper motor 52 is installed on one side of the first transmission device 51, and a spur gear is installed inside the control seat 54. The center of the spur gear is fixedly connected to the corresponding second transmission device 53. Multiple teeth 551 are axially arranged on one side of the push rod 55, and the tooth surface of the spur gear meshes with the teeth 551. Thus, the first transmission device 51 and the second transmission device 53 synchronously transmit the power of the stepper motor 52 to the control seat 54, so that the four push rods 55 move synchronously, thereby realizing the stable movement of the rear end plate 3.

[0053] Reference Figure 7The transmission device 51 has a rotating ring gear 511 inside, and a frame 512 is fixedly installed on the inner side of the ring gear 511. An intermediate shaft 513 is fixedly installed in the center of the frame 512. The axis of the intermediate shaft 513 is perpendicular to the end face of the ring gear 511, and the two ends of the intermediate shaft 513 are located at the two ends of the ring gear 511, and a bevel gear 514 is fixedly installed at the end.

[0054] The output end of the stepper motor 52 is provided with an input shaft 521. One end of the input shaft 521 is rotatably disposed inside the transmission 51, and a drive wheel 522 is fixedly installed at the end. The tooth surface of the drive wheel 522 meshes with the ring gear 511. Thus, the stepper motor 52 drives the ring gear 511 to rotate through the drive wheel 522. The ring gear 511 drives the intermediate shaft 513 to rotate through the frame 512, and then the bevel gears 514 at both ends rotate synchronously.

[0055] Reference Figure 8 One end of the intermediate shaft 513 away from the frame 512 is located inside the transmission device 53 and is mounted via a bearing. A driven gear disk 531 is rotatably mounted on the inner side of the transmission device 53, and the tooth surface of the bevel gear 514 meshes with the driven gear disk 531. An output shaft 532 is fixedly mounted in the center of the driven gear disk 531, and both ends of the output shaft 532 pass through the driven gear disk 531. The end of the output shaft 532 is fixedly connected to the spur gear in the corresponding control seat 54. Thus, the bevel gear 514 drives the output shaft 532 to rotate through the driven gear disk 531, thereby causing the spur gear in the control seat 54 to rotate synchronously, thereby realizing the synchronous movement of the push rod 55.

[0056] In addition, refer to Figure 1 A fixing rod 13 is installed between the front plate 1 and the rear plate 3 through a clearance fit. The axis of the fixing rod 13 is not on the same straight line as the push rod 55. A thread is provided on one side of the fixing rod 13. Therefore, after the heat exchange plate 4 is installed, the front plate 1 and the rear plate 3 are fixedly connected by nuts after the fixing rod 13 is installed.

[0057] The end face of the front plate 1 is provided with a pair of heat medium inlet and outlet 11, and the end of the heat medium inlet and outlet 11 near the rear plate 3 is connected to the opening 401 of the adjacent heat exchange plate 4; the end face of the front plate 1 is provided with a pair of cold medium inlet and outlet 12, and the end of the cold medium inlet and outlet 12 near the rear plate 3 is connected to the opening 402 of the adjacent heat exchange plate 4; the heat medium inlet and outlet 11 and the cold medium inlet and outlet 12 are arranged symmetrically.

[0058] The method of using the above-mentioned heat exchanger positioning device includes the following steps:

[0059] S1. Start the stepper motor 52 to rotate forward, push the component 5 to control the rear end plate 3 to approach the vertical beam 21; the rear end plate 3 moves to the end of the transverse groove 231 away from the front end plate 1, so that the lower clamping plate 31 and the upper clamping plate 24 are misaligned, and then lock the push component 5.

[0060] S2. The worker arranges the heat exchange plates 4 alternately, one facing forward and the other backward, and places them diagonally in the slots of the upper and lower clamping plates 31.

[0061] S3. After all heat exchange plates 4 are placed, start the stepper motor 52 to reverse and push the component 5 to control the rear plate 3 to move closer to the front plate 1; the lower clamping plate 31 pushes the heat exchange plates 4 to gradually become vertical, and at the same time the heat exchange plates 4 push the upper clamping plate 24 to move upward; when the heat exchange plates 4 are in a vertical state, the upper clamping plate 24 is located at the top of the vertical moving groove 221, and the sliding key 241 is located at the top of the sliding groove 222; then lock the pushing component 5.
