[0001] The utility model relates to the technical field of shell-and-tube heat exchangers, in particular to a sleeve-type shell-and-tube heat exchanger. Background Art
[0002] The sleeve-type shell-and-tube heat exchanger, usually also called a double-pipe heat exchanger or a shell-and-tube heat exchanger, is a heat exchange device widely used in various industrial fields. The double-pipe heat exchanger is composed of concentric sleeves made of straight pipes with different diameters and is connected by U-shaped elbows. This heat exchanger uses the wall surface of the tube bundle enclosed in the shell as the heat transfer surface to achieve heat exchange.
[0003] When the existing sleeve-type shell-and-tube heat exchanger is in use, most of them use bent pipes for heat exchange, which causes local overheating inside the heat exchanger, thus possibly resulting in a lower heat exchange efficiency. At the same time, when most of the existing sleeve-type shell-and-tube heat exchangers are connected to pipes, due to the fixed height, it is difficult to adjust during use, which may cause the connection of the sleeve-type shell-and-tube heat exchanger to be unstable and the device to be easily damaged. Summary of the Utility Model

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0017] Embodiment: As Figures 1-4 shown, the present invention provides a set-type shell-and-tube heat exchanger, including a heat exchanger main body 1 and an installation base 4. The outer surface of the heat exchanger main body 1 is fixedly connected to the top end of the installation base 4. A diverting pipe 5 is rotatably connected inside the heat exchanger main body 1. A first gear 8 is fixedly connected to the outer surface of the diverting pipe 5. A placing plate 6 is fixedly connected to the outer surface of the heat exchanger main body 1. A motor 7 is fixedly connected to the outer surface of the placing plate 6. The output shaft of the motor 7 is fixedly connected to a second gear 12. A plurality of uniformly distributed L-shaped fixing plates 9 are fixedly connected to the bottom end of the installation base 4. A height adjustment assembly is provided between the inside of the L-shaped fixing plate 9 and the inside of the installation base 4. By setting the motor 7 and the diverting pipe 5, the motor 7 can drive the diverting pipe 5 to rotate inside the heat exchanger main body 1, so as to perform uniform heat exchange inside the heat exchanger main body 1, preventing local overheating inside the heat exchanger main body 1 from resulting in low heat exchange efficiency. The number of L-shaped fixing plates 9 is multiple and they are evenly distributed in a rectangular array at the bottom end of the installation base 4, enabling the device to be stably placed on the ground. The outer surface of the second gear 12 meshes with the outer surface of the first gear 8, so that the rotation of the second gear 12 can drive the rotation of the first gear 8. A liquid inlet pipe 3 is fixedly connected and communicated inside the heat exchanger main body 1, and a liquid outlet pipe 2 is fixedly connected and communicated inside the heat exchanger main body 1, enabling liquid to be introduced into the heat exchanger main body 1 through the liquid inlet pipe 3 and enabling the liquid inside the heat exchanger main body 1 to be discharged from the liquid outlet pipe 2.
[0018] The height adjustment component includes a support leg 10. A first chute 19 is formed inside an L-shaped fixing plate 9, and a second chute 15 is formed inside an installation base 4. A fixing groove 16 is formed inside the L-shaped fixing plate 9. A fixing rod 18 is rotatably connected inside the fixing groove 16. A hand turntable 11 is fixedly connected to the outer surface of the fixing rod 18, and a third gear 17 is fixedly connected to the outer surface of the fixing rod 18. The outer surface of the support leg 10 is slidably connected to the inside of the first chute 19, and the outer surface of the support leg 10 is slidably connected to the inside of the second chute 15. A stopper 13 is slidably connected inside the L-shaped fixing plate 9. By providing the support leg 10, the support leg 10 can slide out of the L-shaped fixing plate 9 to connect the heat exchanger main body 1 to pipes of different heights, ensuring its stability and preventing damage to the device. The inside of the first chute 19 is connected to the inside of the second chute 15, and the inside of the first chute 19 is connected to the inside of the fixing groove 16. Rotating the third gear 17 can drive the support leg 10 to slide inside the first chute 19 and the second chute 15. A rack 14 is fixedly connected to the outer surface of the support leg 10, and the outer surface of the third gear 17 meshes with the outer surface of the rack 14. Rotating the third gear 17 can drive the support leg 10 to slide inside the L-shaped fixing plate 9. A through groove 20 is formed on the outer surface of the L-shaped fixing plate 9, and the outer surface of the stopper 13 is slidably connected to the inside of the through groove 20. The stopper 13 slides in the through groove 20 and enters the gap of the third gear 17, thereby fixing the third gear 17.
[0019] Working principle: When the heat exchanger main body 1 needs to be connected to a pipe, the worker can pull the stopper 13 to make the stopper 13 slide in the through groove 20 and withdraw from the gap of the third gear 17. Then the worker can rotate the hand turntable 11. The rotation of the hand turntable 11 drives the third gear 17 to rotate. The rotation of the third gear 17 makes the support leg 10 slide in the second chute 15 and the first chute 19 through the rack 14, so that the support leg 10 slides out of the L-shaped fixing plate 9 to adjust the height of the heat exchanger main body 1. When adjusted to the appropriate position, the worker can push the stopper 13 again to make the stopper 13 slide in the through groove 20 and enter the gap of the third gear 17, thereby fixing the third gear 17, enabling the heat exchanger main body 1 to be connected to pipes of different heights, ensuring its stability and preventing damage to the device. When heat exchange operation is required, the worker can start the motor 7. The rotation of the output shaft of the motor 7 drives the second gear 12 to rotate. The rotation of the second gear 12 makes the first gear 8 rotate. The rotation of the first gear 8 drives the flow-dividing pipe 5 to rotate inside the heat exchanger main body 1. Then the worker can introduce superheated liquid into the flow-dividing pipe 5. The superheated liquid can uniformly exchange heat with the liquid introduced into the heat exchanger main body 1 from the liquid inlet pipe 3 under the action of the rotating flow-dividing pipe 5, and then be discharged from the liquid outlet pipe 2, preventing local overheating inside the heat exchanger main body 1 and resulting in low heat exchange efficiency.
[0020] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and its equivalent technologies, the present utility model also intends to include these modifications and variations.
