[0046] The overall working principle is that during the long-term use of the plate heat exchanger, the heat exchange plate 3 in the heat exchanger will need to be disassembled and replaced to maintain the entire heat exchanger. At this time, the rotating rods 402 on both sides of the mounting frame 1 are rotated to allow the rotating rods 402 to be clamped with the fixed frames 404 on both sides of the auxiliary frame 2, and then the limit frame 407 is plugged into the card slots 406 opened on the surfaces of both sides of the fixed frame 404, and then the connecting plate 408 is plugged into the positioning column 409, and then the two ends of the connecting plate 408 are plugged and fixed to the rotating rod 402, and finally the rotating shaft 410 is threadedly connected with the positioning column 409, so that the rotating shaft 410 squeezes and fixes the entire connecting plate 408, thereby effectively and conveniently performing the disassembly operation on the mounting frame 1 and the auxiliary frame 2 in the entire heat exchanger.

[0047] When installing and fixing the position of the entire plate heat exchanger, in order to facilitate the horizontal movement and fine-tuning of the heat exchanger, the slide plate 51 and the support frame 52 fixed at the bottom of the mounting frame 1 and the auxiliary frame 2 are slid, and then the fixing plate 54 made of elastic material on one side of the mounting frame 1 is used to allow the block 56 at the bottom of the fixing plate 54 and the rack 58 fixed on one side of the support frame 52 to be engaged and limited, thereby effectively and conveniently adjusting the position of the entire heat exchanger.

[0048] During the disassembly of the entire heat exchanger, the heat exchange plate 3 in the heat exchanger will be replaced and fixed. At this time, in order to facilitate the protective limit of the position of the heat exchange plate 3, first rotate the rotating column 803 on the surface of the auxiliary frame 2, and let the rotating column 803 drive the limit frame 801 to slide along the limit column 802, and then use the sliding rod 804 and the slider 805 on the inner wall of the limit frame 801 to slide, and at the same time, let the positioning frame 807 on the lower surface of the slider 805 to clamp and limit the position of the heat exchange plate 3, with the help of the baffle 810 rotating at the upper end of the slider 805, the baffle 810 and the inlay frame 811 on one side of the limit frame 801 are plugged and fixed, so that the position of the heat exchange plate 3 can be fixed quickly and efficiently.

[0049] When the butt-jointed tube 10 and the connecting tube 6 are docked and fixed, in order to guide and limit the butt-jointed tube 10 and the connecting tube 6, the limiting ring 902 on the surface of the butt-jointed tube 10 is first plugged into the arc surface of the connecting tube 6, and then the limiting ring 902 is docked with the fixing ring 904, and then the moving rod 907 that slides through the surface of the arc surface positioning plate 905 of the fixing ring 904 is pulled to allow the limiting block 909 at the bottom of the moving rod 907 to be plugged and fixed into the limiting hole 903 opened on the surface of the limiting ring 902, and at the same time, the moving rod 907 is subjected to the tensile force generated by the spring 908 to squeeze and fix the position of the limiting block 909 to prevent the limiting block 909 from falling off, thereby allowing the entire butt-jointed tube 10 and the connecting tube 6 to be quickly guided for docking and limiting.

[0050] Water is generally used as the medium in the connecting pipe 6 for cooling. After a certain period of use, scale will form on the inner wall of the connecting pipe 6, thereby reducing the heat transfer coefficient and the heat exchange efficiency. At this time, the inner wall of the connecting pipe 6 can be cleaned with the help of the cleaning device 11. First, the mounting plate 1101 is abutted against the position of the mounting frame 1 corresponding to the connecting pipe 6, and the adjusting rod 1104 on the surface of the adjusting plate 1103 is rotated at the same time, so that the adjusting rod 1104 drives the adjusting plate 1103 and the surface of the mounting frame 1 to squeeze and limit, and then pull the mounting plate 1101 to the mounting frame 1. After the movable plate 1107 in the surface connecting block 1105 reaches the specified position, the positioning shaft 1106 on the upper surface of the connecting block 1105 is rotated to allow the positioning shaft 1106 to squeeze and limit the position of the movable plate 1107. The driving motor 1108 at the bottom of the movable plate 1107 drives the rotating shaft 1109 to rotate, so that the cleaning cloth 1110 on the surface of the rotating shaft 1109 and the connecting strip 1111 made of cemented carbide can use the rotation force to clean the inner wall of the connecting pipe 6, which is convenient for better operation and use of the entire plate heat exchanger.
