[0026] Example 1:

[0027] A high-temperature heat exchanger includes a heat exchanger body 1, with both ends of the heat exchanger body 1 fixedly mounted on a fixed support frame 5. A left detachable shell 2 and a right detachable shell 3 are respectively provided at both ends of the heat exchanger body 1 via connecting flanges 4. A spiral heat exchange tube 8 is centrally disposed within the inner cavity of the heat exchanger body 1. A stirring mechanism 11 is centrally disposed within the inner side of the spiral heat exchange tube 8. The stirring mechanism 11 is used to stir the hot liquid within the inner cavity of the heat exchanger body 1 to improve heat exchange efficiency.

[0028] A moving mechanism 12 is provided between the bottom of the left disassembly shell 2 and the fixed support frame 5. The moving mechanism 12 facilitates the disassembly and assembly of the spiral heat exchange tube 8 and the stirring mechanism 11 in the inner cavity of the heat exchanger body 1, thereby improving the disassembly and assembly efficiency.

[0029] The top and bottom of the left disassembly shell 2 are respectively provided with a cold liquid inlet pipe 6 and a cold liquid outlet pipe 7, which are respectively connected and fixed to the two ends of the spiral heat exchange tube 8 through connecting parts. By providing the cold liquid inlet pipe 6 and the cold liquid outlet pipe 7, and the cold liquid inlet pipe 6 and the cold liquid outlet pipe 7 are respectively connected and fixed to the two ends of the spiral heat exchange tube 8 through connecting parts, the spiral heat exchange tube 8 is centrally positioned, connected and fixed, which facilitates the disassembly and assembly of the spiral heat exchange tube 8.

[0030] A hot liquid inlet pipe 9 is provided above one end of the heat exchanger main body 1 , and a hot liquid outlet pipe 10 is provided at the bottom of the right detachable shell 3 .

[0031] The moving mechanism 12 includes a moving support plate 121, a moving wheel 122 and a positioning slide 123. The moving support plate 121 is fixedly installed at the bottom end of the left disassembly shell 2. The moving wheel 122 is provided at the bottom of the moving support plate 121. The positioning slide 123 is symmetrically arranged on both sides of the moving support plate 121, and the positioning slide 123 is symmetrically connected to the inside of the fixed support frame 5.

[0032] The moving mechanism 12 further includes a sliding groove 124 provided inside the fixed support frame 5 , and the sliding groove 124 is slidably connected to the positioning slide rod 123 .

[0033] Lifting rings are fixedly installed above both ends of the heat exchanger body 1, and the lifting rings facilitate the lifting of the heat exchanger.

[0034] In this embodiment, the left disassembly shell 2 and the right disassembly shell 3 are detachably provided at both ends of the heat exchanger body 1, so as to facilitate the disassembly and assembly of the heat exchanger as a whole. A moving mechanism 12 is provided between the bottom of the left disassembly shell 2 and the fixed support frame 5. The moving mechanism 12 is used to realize the horizontal movement of the positioning of the left disassembly shell 2 and the spiral heat exchange tube 8 and the stirring mechanism 11 provided inside the left disassembly shell 2, so as to facilitate the disassembly and assembly of the spiral heat exchange tube 8 and the stirring mechanism 11, thereby facilitating the subsequent disassembly and maintenance. During the disassembly process, first remove the bolts on the connecting flange 4 between the heat exchanger body 1 and the left disassembly shell 2, and then directly pull the left disassembly shell 2 to one side. Due to the moving wheel 122 at the bottom of the movable support plate 121 at the bottom of the left disassembly shell 2, the left disassembly shell 2 and the structure thereon are moved horizontally to one side, and are moved out of the inner cavity of the heat exchanger main body 1.

[0035] Example 2:

[0036] Based on the first embodiment, the stirring mechanism 11 mentioned in the first embodiment is described as follows:

[0037] The stirring mechanism 11 includes a servo motor 111 and a stirring rod 112. The servo motor 111 is fixedly installed at the center of the end of the left disassembly shell 2, and the output end of the servo motor 111 is connected and fixed to one end of the stirring rod 112 through a coupling. The stirring rod 112 is arranged at the center of the inner side of the spiral heat exchange tube 8 and is located in the inner cavity of the heat exchanger body 1.

[0038] In this embodiment, a stirring mechanism 11 is provided in the inner cavity of the heat exchanger body 1, and the stirring mechanism 11 is provided at the center of the inner side of the spiral heat exchange tube 8. The stirring mechanism 11 is driven to stir the liquid in the inner cavity of the heat exchanger body 1. The stirring rod 112 is driven by the servo motor 111 to rotate, and the rotation of the stirring rod 112 is used to stir the liquid, thereby achieving sufficient heat exchange of the liquid, avoiding the occurrence of local uneven heat exchange, and ensuring the heat exchange effect of the liquid.

[0039] Working principle: First, cold liquid is added through the cold liquid inlet pipe 6, and then flows out from the cold liquid outlet pipe 7 through the spiral heat exchange tube 8. Hot liquid is added to the inner cavity of the heat exchanger body 1 through the hot liquid outlet pipe 9. After the hot liquid exchanges heat with the cold liquid in the spiral heat exchange tube 8, the hot liquid is discharged through the hot liquid outlet pipe 10. In the heat exchange process, the operation of the stirring mechanism 11 can fully stir the hot liquid in the inner cavity of the heat exchanger body 1, avoiding the occurrence of local uneven heat exchange of the liquid during the heat exchange process, thereby ensuring the heat exchange effect of the liquid, thereby achieving sufficient heat exchange of the liquid;

[0040] When it is necessary to clean and maintain the inner cavity of the heat exchanger main body 1 or the spiral heat exchange tube 8, first remove the bolts on the left connecting flange 4, and then pull the left disassembly shell 2 to one side through the moving mechanism 12 to move the left disassembly shell 2 and the spiral heat exchange tube 8 on the left disassembly shell 2 and the stirring mechanism 11 as a whole, so that the spiral heat exchange tube 8 is removed from the inner cavity of the heat exchanger main body 1, thereby facilitating the disassembly and maintenance of the heat exchanger and improving the convenience of disassembly and assembly.
