Description

Technical Field

[0001] This utility model relates to the field of plate evaporator technology, specifically a plate evaporator. Background Technology

[0002] A plate evaporator is an evaporation device that uses metal plates instead of round tubes as heat transfer elements. These evaporators are inexpensive and the scale buildup on the plates is easy to remove, but the rigidity and strength of the plates are far lower than that of round tubes. To improve the rigidity and strength of the metal plates, various heating elements with different structures have emerged, such as spiral heating elements and expanded plate heating elements. Some existing plate evaporators require operators to install the rising and falling films on the equipment and then push a moving plate to stack and fix multiple rising and falling films together.

[0003] A plate evaporator (publication number: CN219423728U) is disclosed in the prior art, including a base plate and a first support rod disposed on the base plate. The first support rod has an mounting portion, which includes a lifting film, a limiting portion, and a fixing portion. The mounting portion includes a convex crossbar and a fixing plate disposed on the convex crossbar. The convex crossbar is mounted on the first support rod, and a fixing rod is disposed between the fixing plate and the first support rod. The plate evaporator provided by this utility model can organize multiple lifting films and achieve more even compression and fixing of multiple lifting films.

[0004] However, the above technical solutions and existing technologies still have the following drawbacks:

[0005] In the process of using this utility model, since the "convex" shaped crossbar is installed on the first support rod, and a fixing rod is provided between the first support rod and the fixing plate, the fixing rod and the "convex" shaped crossbar are used for the installation of the lifting membrane. First, the top of the lifting membrane is placed on the "convex" shaped crossbar, and the bottom of the lifting membrane is placed on the fixing rod. Since the fixing rod and the "convex" shaped crossbar are installed on the first support rod, the first support rod needs to be disassembled from the fixing rod and the "convex" shaped crossbar before the lifting membrane can be disassembled and assembled. This makes the disassembly and assembly process cumbersome and reduces the efficiency of the lifting membrane disassembly and assembly. Utility Model Content

[0006] The purpose of this invention is to provide a plate evaporator to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A plate evaporator includes a first fixed plate and a second fixed plate. An upper sleeve rod and a lower sleeve rod are fixedly installed at the center of the top and bottom ends of the first fixed plate, respectively. The upper sleeve rod and the lower sleeve rod are used for the installation of a lifting film. Three positioning slide rods are fixedly installed between the first fixed plate and the second fixed plate by a first nut. The three positioning slide rods are slidably connected to the interior of a moving plate. The interior of the moving plate is slidably connected to the upper sleeve rod and the lower sleeve rod. A moving component is provided between the center of the back of the moving plate and the second fixed plate. The moving component is used to drive the moving plate to move left and right, which facilitates the installation and removal of the lifting film.

[0009] Preferably, a first through groove is provided at the center of the top and bottom of the movable plate, and the first through groove is slidably connected to the upper sleeve rod and the lower sleeve rod.

[0010] Preferably, the top and bottom sides of the movable plate are provided with second through grooves, and the second through grooves are slidably connected to the positioning slide rod.

[0011] Preferably, the movable component includes a mounting base, a T-slot, a T-shaped rotating block, a screw, and a threaded groove. The mounting base is fixedly installed on the center of the back of the movable plate, and a T-slot is provided inside the mounting base. The T-slot is rotatably connected to one end of the T-shaped rotating block, and the other end of the T-shaped rotating block is fixedly connected to one end of the screw. The screw is threadedly connected to a threaded groove provided inside the second fixed plate, and a gripping part is provided at the other end of the screw.

[0012] Preferably, the first fixed plate and the movable plate have corresponding through slots at the center of their two sides, and the through slots are used for the installation of the side limiting components.

[0013] Preferably, the side limiting assembly includes a limiting side rod and a second nut. The limiting side rod is slidably connected to the through groove, and both ends of the limiting side rod are threadedly connected to the second nut. The second nut is used to fix the limiting side rod in the through groove for limiting the side of the lifting membrane.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting a moving component between the back of the moving plate and the second fixed plate, the moving component drives the moving plate to move left and right, thereby facilitating the assembly and disassembly of the lifting membrane and improving the convenience and efficiency of the assembly and disassembly. First, the moving plate is slidably connected to three positioning slide rods. The T-shaped groove inside the mounting seat in the center of the back of the moving plate is rotatably connected to the T-shaped rotating block fixedly connected to one end of the screw. The screw is threadedly connected to the threaded groove inside the second fixed plate. By holding the gripping part at the other end of the screw, the screw is rotated. The left and right movement of the screw in the threaded groove drives the moving plate to move left and right, thereby adjusting the gap between the moving plate and the sleeve rod and adjusting the installation gap of the lifting membrane, thus facilitating the assembly and disassembly of the lifting membrane.

[0016] 2. By setting through slots and side limiting components, the side of the lifting membrane is limited and fixed to ensure the overall stability of the lifting membrane. After the moving plate moves closer to the lifting membrane and is limited and fixed, the two ends of the limiting side rod are inserted into the through slots on the first fixed plate and the moving plate respectively. After the limiting side rod is limited and fixed to both sides of the lifting membrane, the second nut is used to connect with the threaded connection of the two ends of the limiting side rod. Tightening the second nut fixes the limiting side rod between the first fixed plate and the moving plate, thereby achieving the stability of the limiting side rod. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] Example 1:

[0025] A plate evaporator includes a first fixed plate 1 and a second fixed plate 5. An upper sleeve rod 2 and a lower sleeve rod 3 are fixedly installed at the center of the top and bottom ends of the first fixed plate 1, respectively. The upper sleeve rod 2 and the lower sleeve rod 3 are used for the installation of a lifting film 4. Three positioning slide rods 6 are fixedly installed between the first fixed plate 1 and the second fixed plate 5 by a first nut 7. The three positioning slide rods 6 are slidably connected to the interior of a moving plate 8. One positioning slide rod 6 is located above the upper sleeve rod 2, and the two bottom positioning slide rods 6 are located on the lower sides of the lower sleeve rod 3. The upper positioning slide rod 6 is located above the lifting film 4, and the two bottom positioning slide rods 6 are located below the lifting film 4, which does not affect the installation and removal of the lifting film 4 and facilitates the installation and removal of the lifting film 4. The interior of the moving plate 8 is slidably connected to the upper sleeve rod 2 and the lower sleeve rod 3, and a moving component 9 is provided between the center of the back of the moving plate 8 and the second fixed plate 5. The moving component 9 is used to drive the moving plate 8 to move left and right, which facilitates the installation and removal of the lifting film 4.

[0026] The top and bottom of the movable plate 8 are provided with a first through groove 13. The first through groove 13 is slidably connected to the upper sleeve rod 2 and the lower sleeve rod 3. As the movable plate 8 moves along the positioning slide rod 6 toward the lifting membrane 4, the upper sleeve rod 2 and the lower sleeve rod 3 pass through the second through groove 14, so that the movable plate 8 also moves along the sleeve rod toward the lifting membrane 4, thereby limiting and fixing the lifting membrane 4.

[0027] The top and bottom sides of the movable plate 8 are provided with second through grooves 14, which are slidably connected to the positioning slide rods 6, so that the movable plate 8 can move left and right along the three positioning slide rods 6, ensuring the stability of the movable plate 8 during the movement.

[0028] The movable component 9 includes a mounting base 901, a T-slot 902, a T-shaped rotating block 903, a screw 904, and a threaded groove 905. The mounting base 901 is fixedly installed on the back center of the movable plate 8, and the mounting base 901 has a T-slot 902 inside. The T-slot 902 is rotatably connected to one end of the T-shaped rotating block 903, and the other end of the T-shaped rotating block 903 is fixedly connected to one end of the screw 904. The screw 904 is threadedly connected to the threaded groove 905 inside the second fixed plate 5, and the other end of the screw 904 is provided with a gripping part.

[0029] In this embodiment, a moving component 9 is provided between the back of the moving plate 8 and the second fixed plate 5. The moving component 9 drives the moving plate 8 to move left and right, thereby facilitating the assembly and disassembly of the lifting membrane 4 and improving the convenience and efficiency of the assembly and disassembly of the lifting membrane 4. First, the second through groove 14 opened on the moving plate 8 is slidably connected to three positioning slide rods 6, so that the moving plate 8 moves left and right along the positioning slide rods 6, ensuring the stability of the left and right movement of the moving plate 8. In addition, the T-shaped groove 902 inside the mounting base 901 at the center of the back of the moving plate 8 is rotatably connected to the T-shaped rotating block 903 fixedly connected to one end of the screw 904. The screw 904 is threadedly connected to the threaded groove inside the second fixed plate 5. The gripping part at the other end of the screw 904 rotates the screw 904, causing the screw 904 to be threadedly connected to the threaded groove 905. This also causes the T-shaped rotating block 903 at one end of the screw 904 to rotate in the T-shaped groove 902 inside the mounting base 901. During the rotation of the screw 904 in different directions, the screw 904 moves left and right along the threaded groove 905. When the screw 904 rotates to the right, it pushes the moving plate 8 to move towards the sleeve rod to limit and fix the lifting membrane 4 on the sleeve rod. When the screw 904 rotates to the left, it drives the moving plate 8 to move backward, exposing the installation ends of the upper sleeve rod 2 and the lower sleeve rod 3, which facilitates the installation and removal of the lifting membrane 4.

[0030] Example 2:

[0031] Based on Embodiment 1, the difference from Embodiment 1 is:

[0032] The first fixed plate 1 and the movable plate 8 have corresponding through slots 10 at the center of both sides, which are used for the installation of the side limiting components.

[0033] The side limiting assembly includes a limiting side rod 11 and a second nut 12. The limiting side rod 11 is slidably connected to the through groove 10, and both ends of the limiting side rod 11 are threadedly connected to the second nut 12. The second nut 12 is used to fix the limiting side rod 11 in the through groove 10 for limiting the side of the lifting film 4.

[0034] In this embodiment, by setting the through slot 10 and the side limiting component, the side of the lifting membrane 4 is limited and fixed, ensuring the overall stability of the lifting membrane 4. After the moving plate 8 moves closer to the lifting membrane 4 for limiting and fixing, the two ends of the limiting side rod 11 are inserted into the through slot 10 on the first fixed plate 1 and the moving plate 8 respectively, so that the limiting side rod 11 is limited and fixed to both sides of the lifting membrane 4. Then, the second nut 12 is threadedly connected to the two ends of the limiting side rod 11. Tightening the second nut 12 fixes the limiting side rod 11 between the first fixed plate 1 and the moving plate 8, thereby achieving the stability of the limiting side rod 11.

[0035] Working principle: When the lifting membrane 4 needs to be installed, since the moving plate 8 is far away from the ends of the upper sleeve rod 2 and the lower sleeve rod 3, the lifting membrane 4 is installed on the sleeve rod through the disassembly and assembly gap between the ends of the upper sleeve rod 2 and the lower sleeve rod 3 and the moving plate 8. The top and bottom ends of the lifting membrane 4 are respectively sleeved on the upper sleeve rod 2 and the lower sleeve rod 3. After multiple lifting membranes 4 are installed, the screw 904 is rotated to the right, which pushes the moving plate 8 to move the upper sleeve rod 2 and the lower sleeve rod 3. The upper sleeve rod 2 and the lower sleeve rod 3 pass through the first through groove 13. The moving plate 8 moves towards the lifting membrane 4 on the sleeve rod, which can drive multiple lifting membranes 4 to be stacked together, and limit and fix the installation of the lifting membrane 4. The threaded connection between the screw 904 and the threaded groove 905 ensures the stability of the moving plate 8. Then, the installation of the side limiting component is used to squeeze and tidy up the two sides of the lifting membrane 4 to ensure the stability of the lifting membrane 4, thereby completing the installation.
