Description

Technical Field

[0001] The utility model mainly relates to the technical field of heat exchangers, and specifically relates to a wound tube heat exchanger. Background Art

[0002] As an efficient heat exchange device, the wound tube heat exchanger has been widely used in many industrial fields such as chemical industry, petroleum, and pharmaceuticals. Its core technology lies in achieving efficient heat transfer between fluids through a unique wound tube structure. However, with the continuous development of industrial technology and the increasing requirements for energy conservation and emission reduction, traditional wound tube heat exchangers are difficult to meet the needs of modern industrial production in some aspects. Although existing wound tube heat exchangers already have relatively high heat transfer efficiency, their heat transfer efficiency still needs to be improved under some working conditions with high loads and large temperature differences. This is mainly because there are certain limitations in the traditional design in terms of increasing the heat transfer area and optimizing the fluid flow path. Due to the relatively complex structure of the wound tube heat exchanger, which is mainly reflected in its inner and outer double-layer pipe structure, the design of spherical wound elbows, the arrangement of support frames and inlet and outlet pipes, and the existence of various structural forms, these complexities make it often consume a large amount of manpower and time once a failure occurs or cleaning and maintenance are required while achieving efficient heat transfer.

[0022] Please refer to Figure 1-6 A coiled tube heat exchanger, comprising a cylinder body 1. A cover 2 is movably clamped at the top of the cylinder body 1.

A telescopic block 1701 is slidably arranged between the rotary cover 17 and the clamping block 19. One end of the telescopic block 1701 is arranged on the top of the rotary cover 17. Before the clamping block 19 is inserted into the card slot 1801, it is contracted through the negative pressure of the second spring 21, so that it is contracted with the telescopic block 1701 through the auxiliary rod 20. Then, after being inserted into the card slot 1801 and sliding to the end of the card slot 1801, through the resilience of the second spring 21, a thrust is formed between it and the chuck 18, so that the chuck 18 and the rotary cover 17 are fixedly closed.

[0025] Please refer to Figure 2 Inside the cylinder body 1, a multi-stage coiled tube 5 is arranged. The multi-stage coiled tube 5 is composed of an inner coiled tube and an outer coiled tube. The outer coiled tube is nested with the inner coiled tube. A fixing part 6 is fixedly connected to the bottom inner wall of the cylinder body 1. A latching block fixed to the fixing part 6 is arranged at the bottom of the multi-stage coiled tube 5.

[0026] Please refer to Figure 2 and Figure 3 , the adjusting structure 7 includes a sliding rod 9, a sealing ring 10, a control board 11, a lever 12, a pushing block 1201, a support rod 13, a trigger 14 and a hydraulic end 15. A through block is arranged in the housing 3. The heat input port 8 is located on the right inner wall of the through block. The sealing ring 10 is arranged on the left outer wall of the through block and communicates with the cylinder body 1. The control board 11 is rotatably arranged on the left inner wall of the through block. The sliding rod 9 is fixedly connected to the inner wall of the through block and is positioned directly above the heat input port 8. The end of the lever 12 is fixedly connected to the pushing block 1201. The pushing block 1201 is slidably arranged on the sliding rod 9.

[0027] A first spring 16 is arranged between the pushing block 1201 and the sealing ring 10. The first spring 16 is sleeved on the sliding rod 9. A cavity is arranged between the housing 3 and the through block. The top outer wall of the through block is fixedly connected to the support rod 13. A rotating shaft 1301 is rotatably arranged on the support rod 13. The rod body of the lever 12 is sleeved on the rotating shaft 1301. The trigger 14 is arranged on the left inner wall of the housing 3. The trigger 14 is electrically connected to the temperature sensor 4. The top of the trigger 14 is electrically connected to the hydraulic end 15. The end of the hydraulic end 15 abuts against the top of the lever 12.

[0028] The specific operation process of this utility model is as follows: Cold water enters the cylinder body 1 through the cold input port 102, while hot water enters the adjustment structure 7 through the hot input port 8. The adjustment structure 7 is located directly above the cold input port 102. The temperature sensor 4 monitors the fluid temperature in the cylinder body 1 in real time through the sensing end 401 and transmits the temperature information to the adjustment structure 7 to achieve intelligent adjustment. When the fluid temperature in the cylinder body 1 reaches or exceeds the preset value, the temperature sensor 4 transmits a signal to the trigger 14. After receiving the signal, the trigger 14 activates the hydraulic end 15, and the hydraulic end 15 generates a thrust to push the lever 12 to move. The movement of the lever 12 drives the push block 1201 to slide on the slide rod 9 and simultaneously compresses the first spring 16. During this process, the push block 1201 pushes the control board 11 to control the opening size of the sealing ring 10, thereby adjusting the hot water flow rate entering the cylinder body 1. A decrease in the flow rate means a reduction in heat input, which helps to control the temperature in the cylinder body 1. As the hot water flow rate is adjusted, the temperature in the cylinder body 1 gradually stabilizes within the preset range. At this time, the cold water is heated to the required temperature and is output through the water inlet 201 on the cover 2. If the temperature in the cylinder body 1 is lower than the preset value, the temperature sensor 4 will increase the hot water flow rate again through the adjustment structure 7 to maintain a stable heat exchange effect. When drainage or maintenance is required, the drain port 101 can be opened to drain the fluid in the cylinder body 1. At the same time, gently press the top of the rotary cap 17 by hand to compress the second spring 21, thereby reducing the friction force between the clamping block 19 and the clamping groove 1801. While maintaining the compressed state of the second spring 21, gently rotate the rotary cap 17. As the rotary cap 17 rotates, the clamping block 19 will slide along the track of the clamping groove 1801 and gradually withdraw from the clamping groove 1801. When the clamping block 19 completely withdraws from the clamping groove 1801, the clamping connection between the rotary cap 17 and the chuck 18 is released. At this time, the cover 2 can be disconnected from the cylinder body 1 to facilitate cleaning and inspection of internal components such as the multi-stage wound tube 5.

[0029] The above has made an exemplary description of the present utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as this non-substantial improvement is made by adopting the method concept and technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
