Example

[0023] Generally, multiple plates 13 are set between the left fixed plate 1 and the right fixed plate 12, and are assembled by locking with screws 11 and nuts 14. However, if one of the multiple plates 13 is damaged, it is extremely inconvenient to remove the specific damaged plate 13.

[0024] For this purpose, please refer to Figure 1-5 This utility model provides a detachable plate heat exchanger, which includes a left fixed plate 1. The left fixed plate 1 is fixedly connected to a right fixed plate 12 via a base plate 15. Multiple plates 13 are provided between the right fixed plate 12 and the left fixed plate 1. The bottom ends of the multiple plates 13 are movably connected to the top of the base plate 15. Multiple screws 11 are provided on both sides of the multiple plates 13 and fixed to the outer wall of the left fixed plate 1. The end of each screw 11 away from the left fixed plate 1 is movably extended to the outer side of the right fixed plate 12 and is threaded with a nut 14. A lifting assembly 2 is installed on the base plate 15. The lifting assembly 2 is used to lift a designated single plate 13.

[0025] Further as Figure 1-5As shown, it is worth noting that in order to remove a specific plate 13 among multiple plates 13, a lifting assembly 2 is provided, including a moving groove opened on the base plate 15. A moving seat 21 with an I-shaped vertical cross-section is slidably connected in the moving groove. The bottom end of the moving seat 21 is fixed to the same lifting plate 23 by two symmetrically distributed S-shaped spring pieces 22. A pulling rod 24 is fixed to the top edge of the lifting plate 23 near its front end. A connecting rod 25 is movably sleeved on the outside of the pulling rod 24. The rear end of the connecting rod 25 is fixed to the front end of the moving seat 21. Two symmetrically distributed lifting columns 26 are also movably inserted into the moving seat 21. The bottom ends of the lifting columns 26 are all fixed to the top end of the lifting plate 23. The top of 6 is flush with the top of the base plate 15, and the top of the movable seat 21 is also flush with the top of the base plate 15. The top of the pull rod 24 is fixed with a vertically cross-section inverted L-shaped block 213. The block 213 is movably connected to the top of the base plate 15. The outer wall of the pull rod 24 is also fixed with two symmetrically distributed transmission columns 28. The outer side of the two transmission columns 28 is movably fitted with the same U-shaped operating rod 29. The U-shaped operating rod 29 is rotatably connected to the support rod 210 through the rotating shaft 211. The bottom end of the support rod 210 is fixed to the top of the connecting rod 25. The two side walls of the U-shaped operating rod 29 are provided with transmission grooves 212 that cooperate with the transmission columns 28. The width of the transmission groove 212 is equal to the diameter of the transmission column 28.

[0026] The mounting block 213 is designed to be secured to the top of the base plate 15 by means of the reset action of the S-shaped spring 22, so that the lifting component 2, which is not in use at this time, can be positioned on the base plate 15, thus preventing the lifting component 2 from wobbling from side to side during the installation of the heat exchanger; the width of the transmission groove 212 is equal to the diameter of the transmission column 28.

[0027] In summary: When using this detachable plate heat exchanger, first loosen the multiple nuts 14 so that the right fixed plate 12 no longer locks the multiple plates 13 between the left fixed plate 1. Next, by moving the U-shaped operating lever 29, the moving seat 21 connected to the connecting rod 25 will move its components to the area directly below the plate 13 that needs to be lifted. Then, by manually pressing the U-shaped operating lever 29, the U-shaped operating lever 29 will rotate through the rotating shaft 211. Combined with the setting of the two transmission grooves 212, the lifting column 26 fixed to the two transmission columns 28 will pull the lifting plate 23 upward, thereby compressing the two S-shaped springs 22 and causing the two lifting columns 26 to move upward and lift the plate 13 above. This makes it convenient for manual removal of the plate 13 that needs to be removed, thereby further improving the efficiency of removing the plate 13.
