Description

Technical Field

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

[0002] As a highly efficient heat exchange device, coiled-tube heat exchangers are widely used in a variety of industrial fields, including chemical, petroleum, pharmaceutical, and food industries. They primarily transfer heat through heat exchange between the fluid within the coiled tube and the shell-side fluid. Traditional coiled-tube heat exchangers often lack an effective flow rate regulation mechanism, making it impossible to flexibly adjust the fluid flow rate according to operating conditions in actual applications, thereby affecting heat exchange efficiency. Furthermore, since the coiled tube is typically fixed inside the heat exchanger and is restricted by the flange structure, replacing and cleaning the coiled tube often requires gradually disassembling the bolts at the flange connection. This is not only time-consuming and labor-intensive, but can also damage the equipment and increase maintenance costs. Utility Model Content

[0022] See also Figure 1-5 A coiled tube heat exchanger includes a heat exchanger body 1. The water inlet and outlet of the heat exchanger body 1 are both sleeved with a collar 5. An adjusting ring 4 is slidably provided on the outer wall of the collar 5. A gear plate 6 is rotatably provided at the center of the collar 5. The outer wall of the gear plate 6 is provided with a plurality of teeth. The inner walls on both sides of the adjusting ring 4 are fixedly connected with racks 401. These teeth are engaged with the racks 401 fixedly connected to the inner walls on both sides of the adjusting ring 4. Therefore, when the adjusting ring 4 is slid, the rack 401 will drive the gear plate 6 to rotate. The inner wall of the gear plate 6 is rotatably provided with adjusting teeth 801 distributed in a circular array. The rotation of the gear plate 6 drives the multiple adjusting teeth 801 to swing synchronously toward the axis to adjust the water supply diameter of the inlet and outlet.

[0023] See also Figure 2 The center of the collar 5 is fixedly connected with a sleeve disc 7, and the gear disc 6 is placed on the sleeve disc 7.

[0024] One end of each adjusting tooth 801 is fixedly connected to an adjusting member 8, and the adjusting member 8 is installed inside the ring 5 or on the sleeve disc 7 connected thereto through the rotating shaft 802, so that the adjusting tooth 801 can swing around the rotating shaft 802, and the bottom of the adjusting tooth 801 is provided with a driven tooth that meshes with the teeth on the inner wall of the gear plate 6 to ensure that the adjusting tooth 801 can be synchronously driven to swing when the gear plate 6 rotates.

[0025] See also Figure 1 The two ends of the heat exchanger body 1 are fixedly connected with connecting flanges 3, and the connecting flanges 3 are movably connected with flange covers 2.

[0026] See also Figure 3 、 Figure 4 and Figure 5 The flange cover 2 is provided with an adapting groove 201, which matches the contour of the connecting flange 3 to achieve a snap-on connection. The flange cover 2 is provided with connecting grooves 9 distributed in a circular array, and the connecting flange 3 is provided with a slide groove 301. A fixing bolt 11 is provided in the connecting groove 9 of the slide groove 301, and the fixing bolt 11 is adapted to the slide groove 301.

[0027] A clamping groove 302 is defined on the connecting flange 3 . The clamping groove 302 is located at one end of the sliding groove 301 and is in communication with the sliding groove 301 .

[0028] The fixing bolt 11 is slidably engaged with the card slot 302 to enable the connecting flange 3 and the flange cover 2 to be movably engaged. A tension spring 10 is provided at one end of the fixing bolt 11, and one end of the tension spring 10 is connected to the inner wall of the connecting groove 9. A sealing ring 12 is provided at the center of the inner wall of the connecting flange 3. By rotating the flange cover 2, the fixing bolt 11 in the flange cover 2 slides from the card slot 302 to the slide groove 301, and then slides out of the slide groove 301, and then the adapter groove 201 is disengaged from the connecting flange 3. At this time, the flange cover 2 can be removed to expose the winding pipe, thereby facilitating the user to replace or clean the winding pipe.

[0029] The specific operation process of this utility model is as follows: according to the flow rate to be adjusted, the adjusting ring 4 on the manual sliding collar 5 is engaged with the teeth on the outer wall of the gear plate 6, so the movement of the rack 401 drives the gear plate 6 to rotate, and the rotation of the gear plate 6 meshes with the driven teeth at the bottom of the adjusting teeth 801 through the teeth on its inner wall, driving the multiple adjusting teeth 801 to swing toward or away from the axis synchronously, thereby adjusting the water delivery diameter of the water inlet and outlet, realizing the adjustment of the flow rate, and when it needs to be replaced or cleaned, the water inlet and outlet are adjusted. When winding the pipe in the heat heater body 1, rotate the flange cover 2 to make the fixing bolt 11 slide from the card slot 302 into the slide groove 301. At this time, the tension spring 10 will maintain a certain tension, but the fixing bolt 11 is no longer restricted by the card slot 302. Then the fixing bolt 11 slides out of the slide groove 301, so that the adapter groove 201 and the connecting flange 3 are gradually disengaged. When the adapter groove 201 is completely disengaged from the connecting flange 3, the flange cover 2 can be easily removed, exposing the internal winding pipe and the winding pipe can be taken out for cleaning.
