[0026] For examples, please refer to Figures 1-4 This utility model provides a technical solution:

[0027] A plate positioning structure for a plate heat exchanger includes a mounting plate 1, a positioning plate 2 on the side of the mounting plate 1, a fixing rod 3 and an auxiliary rod 5 fixedly connected to the side of the positioning plate 2 respectively, the auxiliary rod 5 being located at the bottom of the fixing rod 3, the positioning plate 2 being slidably connected to the fixing rod 3 and the auxiliary rod 5 respectively, a heat exchanger plate 6 being disposed between the mounting plate 1 and the positioning plate 2, positioning grooves 10 being opened on the side of the mounting plate 1 and the positioning plate 2 respectively, a positioning rod 11 being disposed between the two positioning grooves 10, the two ends of the positioning rod 11 extending to the side of the mounting plate 1 and the positioning plate 2 respectively, fixing nuts 17 being threaded to the two ends of the positioning rod 11 respectively, mounting gaskets 18 being abutted between the two fixing nuts 17 and the mounting plate 1 and the positioning plate 2 respectively, a connecting strip 12 being fixedly connected to the bottom of the fixing rod 3, a connecting groove 13 being opened on the top of the heat exchanger plate 6, the connecting strip 12 extending into the connecting groove 13 and slidably connected to the connecting groove 13, and two mounting top plates 14 being fixedly connected to the top of the positioning plate 2.

[0028] Among them, the fixing rod 3 and the auxiliary rod 5 play a role in strengthening and stabilizing. When the heat exchanger plate 6 is displaced during use, the fixing nut 17 and the positioning rod 11 work together to tightly connect the mounting plate 1 and the positioning plate 2 together.

[0029] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, two mounting top plates 14 are rotatably connected to mounting rollers 15 via rotating rods 16. Mounting rollers 15 are located at the top of fixed rods 3 and are in rolling connection with fixed rods 3. The sides of mounting plate 1 are respectively fixedly connected to a first connecting pipe 7 and a second connecting pipe 9. Both the first connecting pipe 7 and the second connecting pipe 9 communicate with the heat exchanger plate 6. The sides of the first connecting pipe 7 and the second connecting pipe 9 are respectively fixedly connected to connecting flanges 8. The ends of fixed rods 3 and auxiliary rods 5 are fixedly connected to connecting rods 4. The bottom of connecting rods 4 is fixedly connected to a protective pad. Mounting plate 1 and positioning plate 2 are the same size and are both made of stainless steel. Positioning rod 11 is located on the side of heat exchanger plate 6 and is made of alloy steel. Fixed rods 3 and auxiliary rods 5 are the same length and are coated with anti-corrosion solution on their outer surfaces.

[0030] The connecting strip 12 at the bottom of the fixing rod 3 is slidably connected to the connecting groove 13, which not only simplifies the installation steps but also ensures the precise positioning between the heat exchanger plates 6.

[0031] The working process of this utility model is as follows: When using the plate heat exchanger plate positioning structure designed in this scheme, first check whether the device is working properly and ensure that all components are intact. Place the heat exchanger plate 6 on the side of the mounting plate 1. Through the cooperation of the positioning plate 2 and the positioning groove 10, the heat exchanger plate 6 is initially positioned. Then, the heat exchanger plate 6 is further fixed by the fixing rod 3, the auxiliary rod 5 and the connecting rod 4. The auxiliary rod 5 plays a supporting and stabilizing role, enhancing the stability of the entire structure. At the connection of the first connecting pipe 7 and the second connecting pipe 9, a tight connection is achieved through the connecting flange 8 to prevent medium leakage. The positioning rod 11 and the connecting strip 12 are used to strengthen the connection between the heat exchanger plates 6, improving the strength and stability of the overall structure. The design of the connecting groove 13 makes the connection between the components more convenient and firm. On the mounting top plate 14, the mounting rollers 15 can easily move and adjust the position of the positioning plate 2, improving work efficiency to adapt to different working environments and needs. The mounting gasket 18 plays a wear-resistant and buffering role, protecting the mounting plate 1 and the positioning plate 2 from damage.

[0032] Throughout the entire process, the components work together to achieve precise positioning and fixation of the plate heat exchanger plates, thereby improving heat exchange efficiency and operational stability.
