[0002] Urban centralized heating is an important part of urban municipal administration, in which the heating station is a bridge connecting the urban heating network and the user's heating network. The plate heat exchange unit has a compact structure, reliable operation, and simple and intuitive operation. It is the preferred high-efficiency energy-saving equipment for the heating station. The plate heat exchanger unit is a type of heat exchanger unit. Its characteristic is that it uses a plate heat exchanger. Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of a tube heat exchanger, and the floor area is one-third of that of a tube heat exchanger. The heat recovery rate can be as high as 90% or more.

[0003] At present, a Chinese utility model with announcement number: CN202021491789.2 discloses a plate type heat exchange unit, including a plate heat exchanger, a circulating pump, a hot water tank, a water heater, multiple groups of water pipes, a base, an air pressure pump, an inflation pipe, an air bag, a pressure plate, a buffer spring, a positioning block, an adjusting bolt, a pressure reducing valve and a pressure block. A pressure reducing chamber and a hot water chamber are provided in the hot water tank, and the pressure reducing chamber and the hot water chamber are communicated. The pressure plate is located in the pressure reducing chamber, and the top of the pressure plate is tightly attached to the bottom end of the air bag. The side wall of the air bag is provided with an air inlet, and the top of the air bag is provided with an exhaust port. The output end of the air pressure pump is connected to the air inlet through the side wall of the hot water tank through the inflation pipe, and the exhaust port is connected to the pressure reducing valve. A working chamber is provided in the pressure reducing valve, and the pressure block is located at the lower part of the working chamber, and the top of the pressure block is connected to the bottom end of the buffer spring, and the top of the buffer spring is connected to the bottom end of the positioning block.

[0004] However, the above device still has certain defects. For example, when the plate heat exchanger is blocked and cannot work properly, it must be disassembled and cleaned to remove the impurities inside the plate heat exchanger. This disassembly and reassembly method takes a lot of time and is labor-intensive. If errors occur during assembly, such as leakage, it is necessary to disassemble and reassemble, which is easy to repeat work. In addition, when replacing the heat exchange plates of traditional plate heat exchangers, they are generally fixed with screws. It is troublesome to replace them and requires special tools. At the same time, since the screws are stored separately after disassembly, they are easy to lose. Based on the above problems, we provide an intelligent plate heat exchange unit.

[0027] The fixing mechanism 15 includes a mounting seat 151, a partition plate 152 is bolted to the middle of the inner cavity of the mounting seat 151, through grooves 153 are provided on both the top and bottom sides of the mounting seat 151, a triangular block 154 is slidably connected to the inner side of the through groove 153, a spring 155 is bolted to the outer side of the partition plate 152, and the other end of the spring 155 is bolted to the inner side of the triangular block 154. By arranging the mounting seat 151, the partition plate 152, the through groove 153, the triangular block 154 and the spring 155, the mounting seat 151 can be made It serves as the outer shell and mounting frame of the fixing mechanism 15, and the space in the inner cavity of the mounting seat 151 is separated by a partition plate 152. The triangular block 154 extends to the outside of the mounting seat 151 through the through groove 153, and the connecting plate 17 and the filter screen 16 are fixed by the triangular block 154. The spring 155 will shrink after the triangular block 154 moves into the inner cavity of the mounting seat 151. After the triangular block 154 loses the limit or external force control, the spring 155 will reset the triangular block 154 by its own elastic force.

[0028] The support plate 11 and the movable pressure plate 8 are provided with fixing holes 19 on the front and rear sides, and the inner sides of the fixing holes 19 are provided with first limiting rods 20.

[0029] Brief description of the use process: When replacing the heat exchange plate 12, first turn on the servo motor 5, so that the servo motor 5 is used as a driving source to drive the screw 3 to rotate. During the rotation of the screw 3, the threaded sleeve 4 will drive the horizontal axial movement of the threaded sleeve 4 on its surface. Since the threaded sleeve 4 and one end of the slider 7 are evenly connected to the connecting rod 6, when the threaded sleeves 4 on both sides move in opposite directions, the two sides of the connecting rod 6 are driven and pull the slider 7 to move in opposite directions on the surface of the slide rod 10. At this time, the movable clamping plate 8 is driven and gradually moves toward the inside of the fixed clamping plate 1. Since the extrusion limit of the movable clamping plate 8 on the heat exchange plate 12 fails, the heat exchange plate 12 can be taken out from between the movable clamping plate 8 and the support plate 11, and finally the replacement is completed.

[0030] Embodiment 2:

By setting the third limiting rod 23, the third limiting rod 23 can assist the movable pressure plate 8 to move horizontally axially on the left side of the fixed pressure plate 1, thereby providing horizontal support and limitation for the movable pressure plate 8.

[0034] Brief description of the usage process: after the filter screen 16 inside the heat exchange slot 13 of the heat exchange unit is blocked, the user only needs to press the triangular blocks 154 on both sides of the mounting seat 151. After the triangular blocks 154 shrink inward, they will squeeze the springs 155 in the inner cavity of the mounting seat 151. At this time, the connecting plate 17 and the mounting slot 18 lose the fixed limit of the triangular blocks 154. The user can take out the connecting plate 17 and the filter screen 16 in the heat exchange slot 13 and replace them. After putting the filter screen 16 into the heat exchange slot 13 again, align the mounting slots 18 on both sides of the connecting plate 17 with the mounting seat 151 on the left side of the mounting plate 14, and insert the mounting slot 18 and the triangular blocks 154 into the mounting slot 18. When the triangular blocks 154 pass through the mounting slot 18, the triangular blocks 154 lose their limit, and the springs 155 will push the triangular blocks 154 to move outward through their own elastic force, and finally the triangular blocks 154 on both sides of the mounting seat 151 will fix the connecting plate 17 and the filter screen 16 again.
