Description

Technical Field

[0001] This invention relates to the technical field of plate heat exchanger assembly equipment, specifically to a plate pressing and assembly equipment for plate heat exchangers. Background Technology

[0002] Plate heat exchangers are highly efficient and compact heat exchange devices widely used in various industries such as heating, refrigeration, chemical, food, and pharmaceuticals for heat transfer between liquids or between liquids and vapors. Their core structure consists of an outer frame and plates. The outer frame mainly includes a fixed frame plate, support guide rods, an upper guide rod, a lower guide rod, and a movable clamping plate. During assembly, the mounting slots at the upper and lower ends of the plates are inserted into the upper and lower guide rods respectively, making contact with the support. Then, the movable clamping plate is pushed along the upper / lower guide rods, gradually pressing all the plates together neatly. Finally, the movable clamping plate is tightened and fixed to the fixed frame plate by tightening the screws, ensuring that the plates are tightly pressed together, forming a stable sealed flow channel, allowing for efficient heat exchange between the hot and cold media through the adjacent plates.

[0003] The existing plate assembly method for plate heat exchangers has gradually revealed its shortcomings in practical applications, mainly in the following aspects:

[0004] The plate installation process is cumbersome. Specifically, the mounting slots at the top and bottom of the plates in a plate heat exchanger are recessed, while the bottom and top of the upper and lower guide rods have corresponding protruding structures. This means that the plates cannot be installed by direct insertion. Therefore, the plates must first be tilted and placed between the upper and lower guide rods, then erected and adjusted so that the bottom and top of the upper and lower guide rods can be inserted into the mounting slots at the top and bottom of the plates, respectively. This installation method requires the installer to perform complex operations of tilting, placing, erecting, and aligning each plate one by one, making the entire installation process extremely cumbersome and time-consuming, significantly reducing installation efficiency.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the technical problem to be solved by this invention is to provide a plate clamping and assembly device for plate heat exchangers. This device can simultaneously position, clamp, and install all plates to be installed. Compared with the traditional method of manual installation one by one, it simplifies the plate installation process, significantly shortens the installation cycle, and improves installation efficiency.

[0007] To address the above problems, the present invention provides the following technical solution:

[0008] A plate pressing and assembly device for a plate heat exchanger includes a base, a sliding frame slidably mounted on the top of the base, a moving plate horizontally movable at the end of the sliding frame, a plurality of rotatably mounted U-shaped clamping plates arranged side by side at the end of the moving plate, the plurality of U-shaped clamping plates being synchronously rotated, a plurality of insert posts fixedly mounted on the inner wall of the U-shaped clamping plates, a bearing plate slidably mounted on the top of the base for supporting an outer frame, a plurality of positioning posts fixedly mounted on the top of the bearing plate, a bearing assembly for supporting the plates and a positioning assembly for positioning the plates on the top of the base, and a plurality of slots provided on the opposite sidewalls of the plates.

Several insert rods are fixedly provided at the ends of the fixed plate and the sliding plates. An installation plate is fixedly provided on the side wall of the movable frame, and a pressure plate is horizontally movable at the end of the installation plate.

[0010] As an optimized solution, the end of the movable frame is vertically slidably provided with an adjustment frame, and the end of the adjustment frame is provided with a plurality of guide grooves. The vertical length of the plurality of guide grooves is the same, and the horizontal length increases sequentially from right to left. The end of the sliding plate is fixedly provided with a fixing rod, one end of the fixing rod passes through the movable frame and extends into the guide groove and makes frictional contact with the adjustment frame. The fixing rod avoids the movable frame.

[0011] As an optimized solution, the top of the mobile frame is fixedly provided with several fixed columns, which vertically penetrate the adjustment frame and are slidably connected to the adjustment frame. The top of the mobile frame is fixedly provided with a lifting telescopic cylinder, and the telescopic end of the lifting telescopic cylinder is fixedly connected to the adjustment frame.

[0012] As an optimized solution, a pneumatic telescopic cylinder is fixedly provided at the end of the mounting plate, and the telescopic end of the pneumatic telescopic cylinder passes through the mounting plate and is fixedly connected to the pressure plate.

[0013] As an optimized solution, the load-bearing component includes a fixed frame, four load-bearing columns are fixedly provided at the end of the fixed frame, and a number of T-shaped plates are evenly distributed on the outer wall of the load-bearing columns and slidably arranged along their radial direction. The top surface of the T-shaped plates has an arc-shaped structure.

[0014] As an optimized solution, the bearing column is provided with a sliding shaft that slides along its axial direction inside. The sliding shaft passes through the bearing column. Several support plates are fixedly provided on the outer wall of the sliding shaft in the circumferential direction. Several guide grooves are provided through the ends of the support plates. The bottom end of the T-shaped plate extends downward to the space between two adjacent support plates. Several guide posts are fixedly provided at the opposite ends of the T-shaped plate. The guide posts are located in the guide grooves and are in frictional contact with the support plates.

[0015] As an optimized solution, the end of the fixed frame is provided with a drive plate, and a plurality of control telescopic cylinders are fixedly provided at the end of the fixed frame. The telescopic ends of the control telescopic cylinders are fixedly connected to the drive plate, and one end of the sliding shaft passes through the fixed frame and is fixedly connected to the drive plate.

[0016] As an optimized solution, a number of sliding rods are fixedly provided at the end of the movable plate. The sliding rods pass horizontally through the sliding frame and are slidably connected to the sliding frame. A number of horizontal telescopic cylinders are fixedly provided at the end of the sliding frame. The telescopic ends of the horizontal telescopic cylinders pass through the sliding frame and are fixedly connected to the movable plate.

[0017] As an optimized solution, a rotating shaft is fixedly provided at the end of the U-shaped clamping plate. One end of the rotating shaft passes through the moving plate and is fixedly fitted with a gear. The rotating shaft is rotatably connected to the moving plate. A rack is provided at the end of the moving plate for horizontal movement. The gear meshes with the rack.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. During panel assembly, insert the corresponding number of panels into the four support columns on the fixing frame. Place the outer frame on the support plate and insert the positioning columns into the corresponding holes. Use bolts to fix the outer frame to the support plate (e.g., Figure 3 As shown), the drive plate moves horizontally, the T-shaped plate slides outward until it contacts the plate, the moving frame slides towards the fixed frame and moves to the first preset position. At this time, the insert rod is not inserted into the slot of the plate, the pressure plate moves horizontally, pressing the plate on the bearing column until adjacent plates are in contact and aligned (as shown). Figure 12 As shown), the moving frame continues to slide until the insert rod is inserted into the slot at one end of the plate. The pressure plate resets and moves aside, causing the adjusting frame to slide downwards, which in turn drives all the sliding plates to slide horizontally, thereby adjusting and positioning the corresponding plates. All the plates are arranged according to the set intervals (e.g., Figure 13 As shown), the sliding frame slides to the preset position, the U-shaped clamping plate aligns with the arranged plates one by one, and the moving plate moves horizontally until the plate is inserted into the U-shaped clamping plate. At this time, the insert pin is inserted into the slot at the other end of the plate, thereby clamping the plate (as shown). Figure 14 (As shown), then the moving frame and T-shaped plate reset sequentially, thereby releasing the restriction on the plate. The sliding frame resets, the plate separates from the bearing column, the rack moves horizontally, and under the transmission of the gear and rotating shaft, all U-shaped clamping plates rotate synchronously, thereby tilting the clamped plate (as shown). Figure 15 (As shown on the left), the bearing plate slides horizontally, conveying the outer frame to the designated position. At this time, the inclined plate is located between the upper and lower guide rods. Then, all the U-shaped clamping plates synchronously reset, thereby allowing the bottom end of the upper guide rod and the top end of the lower guide rod to be inserted into the mounting grooves at the upper and lower ends of the plate, respectively (as shown on the left). Figure 15As shown on the right), the installation of the plates is now complete. This equipment can simultaneously position, clamp, and install all the plates to be installed. Compared with the traditional manual installation method, it simplifies the plate installation process, greatly shortens the installation cycle, and improves installation efficiency.

[0020] 2. After the plates are installed, reset the support plate, push the movable clamping plate to gradually press all the plates together, and use the tightening screws to tighten and fix the movable clamping plate to the fixed frame plate. This completes the assembly of the plate heat exchanger (e.g., Figure 16 (as shown)

[0021] 3. When the adjustment frame slides downward, the guide groove enables the plates arranged in contact on the bearing column to quickly separate according to the set interval, thereby creating convenient conditions for the subsequent quick insertion and clamping operation of the U-shaped clamping plate, effectively improving the practicality of the equipment and the overall operating efficiency.

The telescopic ends of the control telescopic cylinders 43 are fixedly connected to the drive plate 42.

[0050] An electrically controlled telescopic cylinder 22 and a hydraulic telescopic cylinder 12 are fixedly installed on the top of the base 1. The telescopic end of the electrically controlled telescopic cylinder 22 is fixedly connected to the sliding frame 9, and the telescopic end of the hydraulic telescopic cylinder 12 is fixedly connected to the bearing plate 11.

[0051] Several sliding rods 23 are fixedly provided at the end of the movable plate 14. The sliding rods 23 horizontally pass through the sliding frame 9 and are slidably connected to the sliding frame 9. Several horizontal telescopic cylinders 24 are fixedly provided at the end of the sliding frame 9. The telescopic ends of the horizontal telescopic cylinders 24 pass through the sliding frame 9 and are fixedly connected to the movable plate 14.

[0052] A rotating shaft 18 is fixedly provided at the end of the U-shaped clamping plate 15. One end of the rotating shaft 18 passes through the moving plate 14 and is fixedly fitted with a gear 21. The rotating shaft 18 is rotatably connected to the moving plate 14. A rack 20 is provided at the end of the moving plate 14 for horizontal movement. The gear 21 meshes with the rack 20.

[0053] A connecting plate 19 is slidably provided at the end of the movable plate 14, and the rack 20 is fixedly connected to the connecting plate 19. A drive telescopic cylinder 17 is fixedly provided at the end of the movable plate 14, and the telescopic end of the drive telescopic cylinder 17 is fixedly connected to the connecting plate 19.

[0054] The working principle of this device is as follows:

[0055] During assembly of the plates 41, the corresponding number of plates 41 are inserted into the four support columns 34 on the fixing frame 8. The outer frame 39 is placed on the support plate 11, and the positioning columns 10 are inserted into the corresponding holes. The outer frame 39 is then fixed to the support plate 11 using bolts (e.g., ...). Figure 3 As shown), the drive plate 42 moves horizontally, the T-shaped plate 33 slides outward until it contacts the plate 41, the moving frame 2 slides towards the fixed frame 8 and moves to the first preset position. At this time, the insertion rod 28 is not inserted into the slot 40 of the plate 41, the pressure plate 25 moves horizontally, pressing the plate 41 on the bearing column 34 until adjacent plates 41 are in contact and aligned (as shown). Figure 12As shown), the moving frame 2 continues to slide until the insertion rod 28 is inserted into the slot 40 at one end of the plate 41. The pressure plate 25 resets and moves aside, and the adjusting frame 6 slides downward, thereby driving all the sliding plates 30 to slide horizontally, thus adjusting and positioning the corresponding plates 41. All the plates 41 are arranged according to the set interval (e.g., Figure 13 As shown), the sliding frame 9 slides to the preset position, the U-shaped clamping plate 15 aligns one-to-one with the arranged plates 41, and the moving plate 14 moves horizontally until the plate 41 is inserted into the U-shaped clamping plate 15. At this time, the insert post 16 is inserted into the slot 40 at the other end of the plate 41, thereby clamping the plate 41 (as shown). Figure 14 (As shown), then the moving frame 2 and T-shaped plate 33 reset successively, thereby releasing the restriction on plate 41. The sliding frame 9 resets, plate 41 separates from the bearing column 34, the rack 20 moves horizontally, and under the transmission of gear 21 and rotating shaft 18, all U-shaped clamping plates 15 rotate synchronously, thereby causing the clamped plate 41 to tilt (as shown). Figure 15 (As shown on the left), the bearing plate 11 slides horizontally, conveying the outer frame 39 to the designated position. At this time, the inclined plate 41 is located between the upper guide rod 46 and the lower guide rod 44. Then, all the U-shaped clamping plates 15 are synchronously reset, thereby allowing the bottom end of the upper guide rod 46 and the top end of the lower guide rod 44 to be inserted into the mounting grooves at the upper and lower ends of the plate 41, respectively (as shown on the left). Figure 15 As shown on the right), the installation of plate 41 is now complete. This equipment can simultaneously position, clamp and install all plates to be installed. Compared with the traditional manual installation method, it simplifies the plate installation process, greatly shortens the installation cycle and improves the installation efficiency.

[0056] After the plates 41 are installed, the support plate 11 is reset, and the movable clamping plate 47 is pushed to gradually press all the plates 41 together. The movable clamping plate 47 is then tightened and fixed to the fixed frame plate 45 using the tightening screw 48. This completes the assembly of the plate heat exchanger (e.g., Figure 16 (as shown)

[0057] When the adjusting frame 6 slides downward, under the action of the guide groove 31, the plates 41 arranged in contact on the bearing column 34 can be quickly separated according to the set interval, thereby creating convenient conditions for the subsequent quick insertion and clamping operation of the U-shaped clamping plate 15, effectively improving the practicality of the equipment and the overall operating efficiency.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them.
