Technical Field

[0001] The utility model relates to the technical field of turbulent plate heat exchangers, in particular to a turbulent plate heat exchanger. Background Art

[0002] Plate heat exchangers are currently widely used equipment for heat exchange between liquid and liquid, liquid and gas. Plate heat exchangers are generally composed of several stacked metal sheets with a certain corrugated shape. Thin rectangular channels are formed between the metal plates, and heat is exchanged through the plates. The structure and heat exchange principle of plate heat exchangers determine that they have the characteristics of compact structure, small footprint, high heat transfer efficiency, large operational flexibility, wide application range, and small heat loss. Turbulence is a flow state in which fluid exchanges heat in a plate heat exchanger.

[0003] During the maintenance of the existing turbulent plate heat exchanger, after the extrusion device is opened, the extrusion force between the metal plates will disappear. When one metal plate is removed, the other metal plates are likely to fall to the side without support, which will greatly increase the time of the maintenance work and affect the efficiency of the maintenance. Therefore, we proposed a turbulent plate heat exchanger to solve the above problems. Utility Model Content

[0024] The first extrusion plate 6 forms an elastic movable structure with the first spring 4 inside the limiting plate 2 in the first slide groove 3 of the limiting plate 2 through the first connecting block 5, so that the first extrusion plate 6 can always squeeze the metal plate installed in the limiting plate 2 through the elastic structure, avoiding the metal plate from tipping over when the metal plate is taken after the second extrusion plate 16 on the right side is moved away during maintenance.

[0025] The first extrusion plate 6 is connected to the block 7 through a slide groove, so that the block 7 can move up and down at the rear side of the first extrusion plate 6, and there is a certain resistance to the movement of the slide groove and the block 7, and it will not move due to its own gravity, so that the movement of the block 7 in the slide groove requires manual operation, and the first extrusion plate 6 forms a buckle fixing structure through the block 7 and the card hole 8 on the limit plate 2, thereby fixing the first extrusion plate 6 pulled by the elastic structure, so that the first extrusion plate 6 can be fixed in one position when the metal plate is installed without affecting the installation.

[0026] The telescopic rod 13 forms a rotating structure with the second connecting block 9 placed on the base plate 1 through the third connecting block 10, the connecting shaft 12, and the rotating structure can open the blocking of the turbulent plate heat exchanger by the telescopic rod 13, so that it is convenient to take it directly from the side during maintenance and installation.

[0027] The limit bolt 11 penetrates the second connecting block 9 and is connected to the card slot in the third connecting block 10, and the limit bolt 11 is a square column, so that the third connecting block 10 at the bottom is fixed by the square structure, so that the position of the telescopic rod 13 can be fixed by the limit bolt 11 after maintenance, so that the position of the telescopic rod 13 is fixed and will not rotate due to force.

[0028] The telescopic rod 13 is connected to the third slide groove 14 in the second extrusion plate 16 through the connecting slider 15, so that the length of the telescopic rod 13 can be adjusted through the third slide groove 14, which is suitable for turbulent plate heat exchangers with different layers of metal plates. At the same time, the inner side of the telescopic rod 13 is a flush structure, so that the metal plates inside the telescopic rod 13 can also be set flush when limiting, and the upper surface of the protrusion on the connecting slider 15 is arc-shaped, and the third slide groove 14 is "T"-shaped, so that the protrusion on the connecting slider 15 can be contracted through the internal second spring 17 and the arc-shaped structure when encountering the third slide groove 14, and then the side is inserted into the "T"-shaped third slide groove 14, and cooperates with the second extrusion plate 16 to move forward and backward.

[0029] Working principle: When using the turbulent plate heat exchanger, first, when assembling the turbulent plate heat exchanger, first pull the first extrusion plate 6 so that the first extrusion plate 6 is translated in the first slide groove 3 in the limiting plate 2, thereby leaving a required size between the first extrusion plate 6 and the placement base plate 1, and then press the blocks 7 on the upper and lower sides of the first extrusion plate 6 so that the blocks 7 follow the slide groove on the first extrusion plate 6 into the card holes 8 on the limiting plate 2, thereby fixing the first extrusion plate 6, and then pull up the limit bolt 11 in the second connecting block 9, and rotate the telescopic rod 13 through the connecting shaft 12. While opening, the arc-shaped protrusion on the connecting slider 15 on the right side of the telescopic rod 13 shrinks with the rotation, and is then taken out of the third slide groove 14 of the second extrusion plate 16, so that one side of the turbulent plate heat exchanger After the filling is completed, the telescopic rod 13 is rotated to limit the internal metal plate, and then the square limit bolt 11 is lowered to fix the third connecting block 10 to prevent it from rotating. The connecting slider 15 on the right side of the telescopic rod 13 enters the third slide groove 14 of the second extrusion plate 16 through the arc surface of the internal second spring 17 after rotation, and then the clamping block 7 on the rear side of the first extrusion plate 6 is pulled to be taken out from the clamping hole 8 on the limiting plate 2, and then the first extrusion plate 6 will move due to the force of the first spring 4, so as to extrude the filled metal plate, and then the outer second extrusion plate 16 is moved to extrude and fix the metal plate and the first extrusion plate 6, thus completing the assembly;

[0030] When maintenance is needed, first open the extrusion of the second extrusion plate 16, then pull up the limiting bolt 11 in the second connecting block 9, and rotate the telescopic rod 13 through the connecting shaft 12, so that the side of the turbulent plate heat exchanger is opened, and at the same time, the first extrusion plate 6 on the upper side limiting plate 2 will squeeze the metal plate between the first extrusion plate 6 and the bottom plate 1 through the action force of the first spring 4 in the limiting plate 2, thereby fixing the metal plate, which is convenient for subsequent maintenance and removal. After the maintenance, rotate the telescopic rod 13 so that the telescopic rod 13 limits the internal metal plate, and then lower the square limiting bolt 11 so that the limiting bolt 11 fixes the third connecting block 10, and then move the second extrusion plate 16 so that the second extrusion plate 16 squeezes the metal plate. At the same time, the telescopic rod 13 shrinks following the movement of the second extrusion plate 16 through the connecting slider 15 to achieve the length of the adapted metal plate layer.
