[0001] The utility model relates to the field of plate heat exchanger, especially to a plate heat exchanger convenient to disassemble. BACKGROUND
[0002] Plate heat exchanger is a new type of high efficiency heat exchanger which is stacked by a series of metal sheets with certain corrugated shape. The working principle of plate heat exchanger is based on heat conduction and convection. When two or more fluids with different temperatures flow through the channels between the plates, heat will be transferred from the high-temperature fluid to the low-temperature fluid due to the temperature difference.
[0003] During actual maintenance, the main body and the outer plate of the plate heat exchanger are usually fixed by screws and nuts. During disassembly and assembly, a large number of screws and nuts need to be loosened and tightened one by one, which not only consumes a lot of time, but also increases the complexity of operation. In addition, screws and nuts are easy to fall off during disassembly and assembly, which not only may cause damage or loss of parts, but also may affect the smooth progress of the next installation. Once the screw or nut is lost or damaged, additional time and resources are needed to replace it, further prolonging the maintenance cycle. SUMMARY

DETAILED DESCRIPTION
[0024] In order to make the technical means, creation features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.
[0025] As Figure 1 - Figure 5 The utility model discloses a plate heat exchanger convenient to disassemble, which mainly comprises a side plate 1, a plate heat exchanger main body 2 and connecting pipes 3. The side plate 1 is arranged at both ends of the plate heat exchanger main body 2, and the connecting pipes 3 are arranged on the end face of the side plate 1, so that the structure of the whole heat exchanger is compact and convenient to operate.
[0026] The side walls of the two side plates 1 are provided with notches, and the notches are designed for the convenience of installation and disassembly. The notch of one side plate 1 is provided with a mounting seat 4, and the end face of the mounting seat 4 is provided with a waist hole 5. The mounting seat 4 can be firmly fixed on the side plate 1 by inserting a mounting bolt 6 through the waist hole 5. The mounting seat 4 is connected with a connecting rod 8 through a hinge device 7, and the connecting rod 8 can be easily clamped into the notches of the two side plates 1 through the rotating action of the hinge device 7. The end of the connecting rod 8 is also provided with a threaded portion 10, and the threaded portion 10 is sleeved with an abutting nut 11, so that the two side plates 1 and the plate heat exchanger main body 2 can be quickly disassembled and assembled through simple operation, and the work efficiency is improved.
[0027] To further enhance the stability and safety of the structure, the side wall of the connecting rod 8 is provided with multiple through holes 9. These through holes 9 are inserted with connecting bolts 12, which are connected with protective auxiliary mounting plates 13. The protective auxiliary mounting plates 13 not only provide additional protection for the side of the plate heat exchanger body 2, but also allow the installation of various auxiliary components to meet different use requirements.
[0028] On one side of the side plate 1, three notches are provided, which are connected with rubber gaskets through adhesive to provide better sealing effect. The edges of the notches are designed in arc shape, which can effectively reduce stress concentration and prolong the service life of the heat exchanger. The upper and lower ends of the side plate 1 are also provided with protrusions, each of which is provided with a threaded hole, which can be used to install other auxiliary equipment.
[0029] To ensure the firm connection between the mounting seat 4 and the side plate 1, two waist holes 5 are symmetrically distributed on the end face of the mounting seat 4. One end of the hinge device 7 is welded on the mounting seat 4, and the waist hole 5 is opposite to the threaded hole on the end face of the side plate 1. By passing the mounting bolt 6 through the waist hole 5 and the threaded hole, the mounting seat 4 and the side plate 1 are firmly fixed, ensuring the stability and reliability of the entire heat exchanger.
[0030] To prevent sliding during disassembly, the end face of the abutting nut 11 is connected with a non-slip rubber gasket through adhesive, increasing the friction. The abutting nut 11 rotates along the threaded portion 10 to connect the connecting rod 8 to the side plate 1, and the connecting rod 8 is fixed with the hinge device 7 by welding, ensuring the stability of the structure. This design not only improves the safety of operation, but also makes the disassembly process more convenient.
[0031] To further reduce vibration and noise, multiple through holes 9 are equally distributed on the connecting rod 8, and the through holes 9 are threaded holes, which are screwed with connecting bolts 12. The connecting bolts 12 are provided with rubber gaskets, which can effectively absorb vibration and reduce noise, providing a more comfortable working environment for operators.
[0032] The end face of the protective auxiliary mounting plate 13 is provided with multiple threaded holes for the auxiliary installation of components. The edges of the protective auxiliary mounting plate 13 are also designed in arc shape to reduce stress concentration. In addition, the end face of the protective auxiliary mounting plate 13 is connected with a buffer rubber pad through adhesive, which can absorb impact force and protect the plate heat exchanger body 2, ensuring its long-term stable operation.
[0033] Place the side plate 1 in the appropriate position, ensuring that its end face is aligned with both ends of the plate heat exchanger body 2. Find the notch on the end face of the side plate 1 and insert the mounting bracket 4 into the notch. Insert the mounting bolt 6 through the waist hole 5 to secure the mounting bracket 4 to the side plate 1. Ensure that the mounting bolt 6 passes through the waist hole 5 and the screw hole in the end face of the side plate 1, and tighten the bolt to ensure a secure connection. Connect the connecting rod 8 to the mounting bracket 4 via the hinge device 7. Rotate the connecting rod 8 so that the threaded portion 10 at its end is inserted into the notch of the other side plate 1. Turn the jam nut 11 along the threaded portion 10 to secure the connecting rod 8 to the side plate 1. Ensure that the jam nut 11 is connected with the non-slip rubber washer to increase friction and prevent slipping. Connect the protective auxiliary mounting plate 13 to the protrusion on the side plate 1 via the bolt. Ensure that the rubber washer and the buffer rubber pad are installed in place to provide additional protection and absorb impact force. Connect the connecting pipe 3 to the end face of the side plate 1, ensuring good sealing effect. Check whether all connected parts are secure and ensure that there is no leakage. Perform a test run to ensure that the heat exchanger is working properly.
[0034] Loosen the jam nut 11 by rotating it counterclockwise, and then loosen the connecting bolt 12 to remove the protective auxiliary mounting plate 13. Completely loosen the jam nut 11 and remove the connecting rod 8. Rotate the connecting rod 8 via the hinge device 7 so that it is disengaged from the notch of the side plate 1.
