Technical Field

[0001] This application relates to the field of evaporators, and more particularly to a plate evaporator. Background Technology

[0002] A plate evaporator is an evaporation device that uses a metal plate instead of a round tube as the heat transfer element. This type of evaporator is inexpensive, and the scale buildup on the plate is easy to remove.

[0004] In actual use, the plate evaporator of the aforementioned patent clamps and fixes the metal plate by rotating bolts. However, when the staff inspects the surface of the internal metal plate, the evaporator cannot fix a certain metal plate individually. The staff needs to use additional tools to fix the plate, which is a cumbersome and inconvenient process for the staff. Utility Model Content

[0009] By adopting the above technical solution, a rotating handle is fixedly installed on the top of the drive rod, which allows the operator to more conveniently drive the second pulley to rotate.

[0010] Preferably, the adjustable auxiliary mechanism further includes a guiding strip fixedly connected to the side wall of the side wall support plate. A sliding block fixedly connected to one end of the moving platform movably penetrates through the side wall of the guiding strip. One end of the sliding block away from the moving platform is fixedly connected to a connecting block. One end of the connecting block away from the sliding block is fixedly connected to a moving member. The top of the connecting block movably penetrates through the rotating rod. A first pulley is fixedly penetrated through the outer wall of the rotating rod. The top of the moving member movably penetrates through the driving rod.

[0011] By adopting the above technical solution, the moving member is arranged in a "Ji" shape, so that the structural connection is more stable and it is more convenient for the staff to operate the mechanism.

[0012] Preferably, the outer wall of the driving rod is fixedly penetrated through a second pulley. A transmission belt is sleeved between the outer wall of the second pulley and the outer wall of the first pulley. A driving gear is fixedly penetrated through the outer wall of the rotating rod. The side wall of the driving gear is meshed with a rack.

[0013] By adopting the above technical solution, the second pulley and the first pulley are at the same vertical height, so that the synchronous transmission of the transmission belt is more stable.

[0014] Preferably, a first limiting block fixedly connected to the top of the moving platform is arranged on the side wall of the rack. A gear ring is meshed with the side wall of the rack. The inner wall of the gear ring is fixedly connected to a moving strip. One side of the moving strip away from the gear ring is in contact with the outer wall of the first threaded rod. A linkage member is arranged inside the moving strip.

[0015] By adopting the above technical solution, a hole through which the rack penetrates is formed on the side wall of the first limiting block, so as to limit the rack.

[0016] Preferably, the side wall of the linkage member is fixedly connected to the first threaded rod. A supporting gear is meshed with the outer wall of the gear ring. A fixing rod fixedly connected to the top of the moving platform movably penetrates through the top of the supporting gear. The outer wall of the first threaded rod threadedly penetrates through the moving platform. A connecting slider is fixedly connected to the outer wall of the second limiting block.

[0017] By adopting the above technical solution, one side of the moving strip close to the first threaded rod is set to be arc-shaped, so that the moving strip can rotate along the surface of the first threaded rod.

[0018] Preferably, a limiting vertical plate fixedly connected to the bottom of the moving platform movably penetrates through the outer wall of the connecting slider. A sliding tube movably penetrating through the side wall of a metal plate is fixedly connected to the side wall of the side wall support plate. A second threaded rod threadedly penetrates through the side wall of the side wall support plate.

[0019] By adopting the above technical solution, the sliding tubes are symmetrically arranged at the four corners of the metal plate, so as to perform precise limiting connection on the metal plate.

[0020] Preferably, a rotating gripper is fixedly connected to one end of the second threaded rod, an extrusion plate is movably passed through the outer wall of the sliding tube, and a moving block is fixedly connected to the top of the motion platform.

[0021] By adopting the above technical solution, the end of the second threaded rod near the extrusion plate contacts the geometric center point of the extrusion plate, thereby making the movement of the extrusion plate more stable.

[0022] Preferably, the movable block has a threaded rod that is movably connected to the side wall of the side wall support plate, and a handle is fixedly connected to one end of the threaded rod. The bottom of the first threaded rod is fixedly connected to a connecting disc that is rotatably connected to the inner wall of the second limiting block.

[0023] By adopting the above technical solution, the moving block is located on the central symmetry line of the motion platform, which makes it easier for the moving block to drive the motion platform to move horizontally, thus making the force transmission more stable.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. A lead screw drives a horizontal motion platform, which in turn drives a second pulley to rotate. The second pulley then drives a rotating rod to rotate, which in turn drives a rack to move horizontally, thereby causing a moving bar to rotate. The moving bar then drives a first threaded rod to rotate. When the first threaded rod rotates, it is limited by the motion platform, causing it to move vertically. This vertical movement of the first threaded rod causes a second limiting block to move vertically as well. This allows the second limiting block to simultaneously limit the top and bottom of the metal plate. As a result, when the extrusion plate is released, the metal plate on the side of the limiting block away from the extrusion plate remains fixed. This allows workers to temporarily fix a portion of the metal plate as needed, facilitating the installation, removal, and cleaning of the metal plate surface. This reduces the workload and operational burden on workers. Attached Figure Description

[0038] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0039] This application discloses a plate evaporator.

[0040] Reference Figure 1A plate evaporator includes a support base 1, a side wall support plate 11 fixedly connected to the top of the support base 1, a side support plate 12 fixedly connected to the side wall of the side wall support plate 11, a metal plate 13 disposed on the side wall of the side wall support plate 11, and an adjustable auxiliary mechanism 2 disposed on the outer wall of the side wall support plate 11. The adjustable auxiliary mechanism 2 includes a rotating rod 25 disposed on the side wall of the side wall support plate 11, a drive rod 27 disposed on the side of the rotating rod 25 away from the side support plate 12, a second pulley 28 fixedly disposed on the side wall of the drive rod 27, a rack 211 disposed on the outer wall of the rotating rod 25, a moving bar 214 disposed on the side wall of the rack 211, a first threaded rod 216 disposed on the side wall of the moving bar 214, and a moving platform 219 disposed on the rack 211. At the bottom of bar 211, limit block 220 is set at the bottom of motion platform 219, extrusion plate 226 is set on one side of metal plate 13, screw 228 is movably passed through the side wall of side support plate 11, and adjustable auxiliary mechanism 2 also includes guide bar 21 fixedly connected to the side wall of side support plate 11. A sliding groove is opened through the side wall of guide bar 21, and sliding block 22 is slidably connected to sliding groove 1, so that sliding block 22 and guide bar 21 are slidably connected. The end of sliding block 22 near motion platform 219 is fixedly connected to one end of motion platform 219, and connecting block 23 is fixedly connected to the end of sliding block 22 away from motion platform 219, so that motion platform 219 and connecting block 23 can achieve synchronous horizontal movement.

[0041] The workers first slidably connected the metal plate 13 to the sliding tube 223. Through this connection method, they successfully stacked multiple metal plates 13 horizontally together. This step provided the foundation for subsequent operations and ensured the initial connection between the metal plates 13.

[0042] Reference Figures 2-4 The moving part 24 is fixedly connected to the end of the connecting block 23 away from the sliding block 22. A circular hole 1 is provided through the top of the connecting block 23, and the circular hole 1 movably passes through the rotating rod 25, thereby allowing the rotating rod 25 to be rotatably connected to the connecting block 23. A circular hole 22 is provided through the top of the first pulley 26, and the outer wall of the rotating rod 25 is fixedly connected through the circular hole 22, thereby allowing the rotating rod 25 to be fixedly connected to the first pulley 26. A circular hole 3 is provided through the top of one side of the moving part 24, and the circular hole 3 movably passes through the drive rod 27, thereby allowing the drive rod 27 to be rotatably connected to the moving part 24. The second pulley... The top of the drive rod 28 has a through hole four, and the outer wall of the drive rod 27 is fixedly connected to the through hole four, so that the drive rod 27 is fixedly connected to the second pulley 28, and the drive rod 27 can drive the second pulley 28 to rotate. The transmission belt 29 is sleeved between the outer wall of the second pulley 28 and the outer wall of the first pulley 26, so that the second pulley 28 and the transmission belt 29 can rotate synchronously. The top of the drive gear 210 has a through hole five, and the outer wall of the rotating rod 25 is fixedly connected to the through hole five, so that when the rotating rod 25 rotates, the drive gear 210 will rotate synchronously.

[0043] To further enhance the stability between the metal plates 13, the operator rotates the rotary gripper 225. This action causes the second threaded rod 224 to rotate, which in turn drives the extrusion plate 226 to push the metal plates 13 to move horizontally. In this way, multiple metal plates 13 are tightly extruded and fixed together to form a stable whole, providing the necessary stability and support for subsequent process steps.

[0044] Reference Figure 5 , Figure 6 The teeth on the side wall of the drive gear 210 mesh with the teeth on the rack 211 near the drive gear 210, so that when the drive gear 210 rotates, it will drive the rack 211 to move horizontally. The bottom of the limiting block 212 is fixedly connected to the top of the motion platform 219, and the limiting block 212 and the rack 211 are movable through each other, so that the rack 211 is limited by the limiting block 212. The teeth on the side wall of the rack 211 mesh with the gear ring 213, so that the drive gear 210 and the gear ring 213 are synchronized. Rotation occurs when the inner wall of the gear ring 213 is fixedly connected to the end of the motion strip 214 near the gear ring 213, and the side of the motion strip 214 away from the gear ring 213 is in contact with the outer wall of the first threaded rod 216. This causes the gear ring 213 to drive the motion strip 214 to rotate in contact with the inner wall of the first threaded rod 216. The two sides of the linkage 215 are in contact with the side walls of the motion strip 214, and the side walls of the linkage 215 are fixedly connected to the side walls of the first threaded rod 216. The outer wall of the gear ring 213 meshes with the outer wall of the support gear 217, and the top of the support gear 217 moves. A connecting hole is provided, through which a fixed rod 218 movably passes, allowing the fixed rod 218 to be rotatably connected to a support gear 217. Multiple support gears 217 stabilize the gear ring 213. The bottom of the fixed rod 218 is fixedly connected to the top of the motion platform 219. A threaded hole is provided at the top of the motion platform 219, through which the outer wall of the first threaded rod 216 is threaded. This ensures that when the first threaded rod 216 rotates, it is limited by the motion platform 219, resulting in vertical movement. The connecting slider 221 is fixed... The limiting vertical plate 222 is fixedly connected to the outer wall of the limiting block 220. The side wall of the limiting vertical plate 222 is provided with a sliding groove 2. The outer wall of the connecting slider 221 is movably connected through the sliding groove 2, so that the connecting slider 221 and the limiting vertical plate 222 are slidably connected. The bottom of the motion platform 219 is fixedly connected to the top of the limiting vertical plate 222. The side wall of the side wall support plate 11 is fixedly connected to the sliding tube 223. The side wall of the metal plate 13 is provided with a mounting hole. The mounting hole is movably connected to the side wall of the metal plate 13, so that the metal plate 13 and the sliding tube 223 are slidably connected.

[0045] When it is necessary to disassemble part of the metal plate 13 for maintenance or replacement, the staff took a meticulous operating procedure. They first turned the handle 229, which caused the lead screw 228 to rotate. Through a series of chain reactions, the motion platform 219 was finally moved horizontally to the top of the target metal plate 13. At this point, they stopped turning the handle 229 and prepared to proceed to the next step. Next, by turning the drive rod 27, they drove a series of components to rotate or move horizontally in sequence. This series of complex mechanical actions finally enabled the limit block 220 to move downward and contact the top of the target metal plate 13, thereby achieving the snap-fit ​​and fixation of the metal plate 13.

[0046] Reference Figure 7 , Figure 8 The side wall support plate 11 has a threaded hole 2 through its side wall. The second threaded rod 224 is threaded through the threaded hole 2, so that the second threaded rod 224 will move horizontally when it rotates. The rotating gripper 225 is fixedly connected to one end of the second threaded rod 224, so that the operator can easily control the rotation of the second threaded rod 224. The side wall of the extrusion plate 226 has a circular hole 6 through its side wall. The outer wall of the sliding tube 223 moves through the circular hole 6, so that the extrusion plate 226 and the sliding tube 223 are slidably connected. The top of the motion platform 219 is fixedly connected to the bottom of the moving block 227. The side wall of the moving block 227 has a threaded hole 3 through its side wall. The lead screw 228 is threaded through the hole 228. The threaded rod 228 rotates through the movable block 227, causing the movable block 227 to move horizontally when the screw rod 228 rotates. The side wall support plate 11 has a circular hole 7 through it, and the screw rod 228 moves through the circular hole 7, so that the screw rod 228 is rotatably connected to the side wall support plate 11. The handle 229 is fixedly connected to one end of the screw rod 228 to facilitate the rotation of the screw rod 228. The connecting disc 230 is fixedly connected to the bottom of the first threaded rod 216. The connecting disc 230 is rotatably connected to the inner wall of the limiting block 220. Then, the connecting slider 221 is limited by the cooperation of the limiting vertical plate 222, thereby completing the directional guidance of the vertical movement of the limiting block 220.

[0047] After the second limiting block 220 successfully engages the target metal plate 13, the operator rotates the rotating gripper 225 again, causing the pressing plate 226 to release the pressure on the metal plate 13. At this time, due to the limiting effect of the second limiting block 220, the engaged metal plate 13 is firmly fixed, while other unaffected metal plates 13 remain in their original state. This design not only allows the operator to easily disassemble and install specific metal plates 13, but also effectively prevents other metal plates 13 from being in a loose state and affecting the stability and safety of the entire system when processing a certain metal plate 13. At the same time, this also provides great convenience for daily maintenance and inspection work.

[0048] The implementation principle of a plate evaporator according to an embodiment of this application is as follows:

[0049] Workers slide the metal plate 13 and sliding tube 223 to achieve horizontal stacking. Rotating the rotary gripper 225 drives the second threaded rod 224 to rotate, which in turn pushes the extrusion plate 226 to make the metal plate 13 move horizontally and be extruded and fixed. When disassembly is required, rotating the handle 229 drives the moving block 227 to move horizontally, so that the moving platform 219 moves to the top of the target metal plate 13. Then, rotating the drive rod 27 causes the first threaded rod 216 to move vertically through a series of transmissions. The second limiting block 220 clamps the top of the metal plate 13 downwards. Rotating the rotary gripper 225 releases the extrusion on the metal plate 13. The second limiting block 220 limits and fixes part of the metal plate 13, which is convenient for disassembly, installation and daily maintenance, and prevents loosening from affecting the process.

[0050] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
