[0007] As a further technical solution of this utility model, the enamel disc and the card block are an integral structure, and the number of card blocks is twice the number of enamel discs, and the mounting slot is compatible with the card block.

[0008] As a further technical solution of this utility model, the slot penetrates the middle of the enamel disc, and the inner edge of the enamel disc has an arc-shaped structure. The enamel disc is adapted to the outer side of the exchange tube, and the liquid inlet and liquid outlet are both connected to the liquid inlet.

[0009] As a further technical solution of this utility model, the number of rotating columns is two sets and they are symmetrically distributed. The heat exchanger support has a through hole in the middle that matches the rotating columns. A bearing is provided at the connection between the rotating columns and the heat exchanger support. The limiting strip is fixedly connected to the rotating columns.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 This utility model provides a technical solution for an enamel disc heat exchanger for compound preparation: an enamel disc heat exchanger for compound preparation includes a heat exchanger support 1, an enamel disc 2 is disposed inside the heat exchanger support 1, an installation groove 11 is provided on the inner wall of the heat exchanger support 1, a locking block 21 is provided on the outer side of the enamel disc 2, a locking groove 22 is provided in the middle of the enamel disc 2, an exchange tube 3 is provided in the middle of the heat exchanger support 1, and an inlet 4 and an outlet 5 are connected to both ends of the exchange tube 3, and a disassembly assembly 6 is provided between the heat exchanger support 1 and the enamel disc 2;

[0023] The disassembly assembly 6 includes a rotating column 61, a limit strip 62 on the outer side of the rotating column 61, a support base 63 connected to the end of the rotating column 61, a hand-held block 64 on the outer side of the support base 63, a limit groove 65 on the outer side of the enamel disc 2, a moving hole 66 and a compression groove 67 in the middle of the support base 63, a positioning column 68 inside the moving hole 66, a positioning groove 69 on the outer side of the heat exchanger bracket 1, a connecting block 610 on the outer side of the positioning column 68, a compression spring 611 on one side of the connecting block 610, and a protrusion 612 connected to one end of the positioning column 68.

[0024] like Figure 1-4As shown, the enamel disc 2 and the locking block 21 are an integral structure, and the number of locking blocks 21 is twice the number of enamel discs 2. The mounting groove 11 is adapted to the locking block 21. The locking groove 22 passes through the middle of the enamel disc 2, and the inner edge of the enamel disc 2 has an arc-shaped structure. The enamel disc 2 is adapted to the outer side of the heat exchange tube 3. The outer side of the enamel disc 2 is coated with an enamel glaze layer, which can resist strong acid and strong alkali media (such as sulfuric acid, hydrochloric acid, etc.) and is suitable for corrosive environments such as chemical and pharmaceutical industries. The liquid inlet 4 and the liquid outlet 5 are connected to the liquid inlet 4, which facilitates the insertion of the enamel disc 2 into the heat exchanger bracket 1 and facilitates contact with the outer surface of the heat exchange tube 3.

[0025] like Figure 3-6 As shown, there are two sets of rotating columns 61, symmetrically distributed. The heat exchanger support 1 has a through hole in the middle that matches the rotating columns 61. A bearing is provided at the connection between the rotating columns 61 and the heat exchanger support 1. The limiting strip 62 is fixedly connected to the rotating columns 61. The limiting strip 62 is matched with the limiting groove 65, and the limiting groove 65 has an arc-shaped structure, which facilitates the limiting strip 62 to be driven into the limiting groove 65 during the rotation of the rotating columns 61, thereby fixing the enamel disc 2. The support base 63 is fixedly connected to the rotating columns 61. The outer side of the hand block 64 is provided with an anti-slip strip. The moving hole 66 is connected to the compression groove 67, which facilitates the subsequent movement of the positioning column 68.

[0026] like Figure 3-6 As shown, the positioning pins 68 and positioning grooves 69 are adapted to each other, and the number of positioning grooves 69 is twice the number of positioning pins 68. The protrusions 612 and connecting blocks 610 are fixedly connected to the positioning pins 68. The compression spring 611 is wrapped around the outside of the positioning pins 68, and its two ends are connected to the connecting blocks 610 and the compression grooves 67 respectively, which is conducive to the positioning of the support base 63, and further positions the rotating pins 61 and the limiting strips 62 to prevent them from shifting their positions.

[0027] The working principle of this utility model is as follows: During the use of the heat exchanger, the enamel disc 2 is inserted into the interior of the mounting slot 11 through the locking block 21, and contacts the outside of the exchange tube 3 through the locking slot 22. Then, the remaining enamel discs 2 are inserted in the same way as described above. Finally, the disassembly assembly 6 is used to position them. At the same time, when the enamel disc 2 needs to be disassembled individually, the disassembly assembly 6 is also required to release the limiting position of the enamel disc 2.

[0028] It should be noted that, through the setting of disassembly component 6, when the enamel disc 2 needs to be disassembled, the user pulls the protrusion 612, causing the positioning pin 68 to move along the inside of the moving hole 66 and the positioning groove 69, so that the connecting block 610 moves along the inside of the compression groove 67, and at the same time, the compression spring 611 is compressed until the positioning pin 68 is disengaged from the inside of the positioning groove 69. Rotating the hand block 64 causes the support base 63 and the rotating pin 61 to rotate, thereby causing the limiting strip 62 to rotate out along the inner side of the limiting groove 65, thus... Release the limiting position on the enamel disc 2. When rotated 90 degrees, the positioning pin 68 corresponds to another set of positioning grooves 69. Release the protrusion 612. Under the elastic potential energy of the compression spring 611, the positioning pin 68 is inserted into the interior of the other set of positioning grooves 69, positioning the support base 63, the rotating pin 61, and the limiting strip 62, thereby facilitating the disassembly of the enamel disc 2. Similarly, the other set of disassembly components 6 is also positioned using the above operation, thereby allowing the enamel disc 2 to be quickly disassembled, facilitating the replacement and cleaning of the enamel disc 2.

[0029] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
