[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example: Reference Figure 1-Figure 4 The automatic dust cleaning device of a vertical tube heat exchanger shown in the figure includes two T-shaped frames 1, and the sides of the two T-shaped frames 1 close to each other are fixedly installed with a fixed plate 2. The top of the fixed plate 2 is evenly provided with two first rotation holes and multiple second rotation holes. Vertical studs 3 are rotatably installed in the two first rotation holes, and hexagonal rotation rods 4 are rotatably installed in the multiple second rotation holes. A movable plate 5 is commonly threadedly sleeved on the two vertical studs 3, and an anti-slip baffle 21 is fixedly installed at the bottom ends of the two vertical studs 3. A plurality of third rotation holes are evenly provided on the top of the movable plate 5, and hollow rotation rods 6 are rotatably installed in the multiple third rotation holes. The multiple hollow rotation rods 6 are respectively slidably sleeved on the multiple hexagonal rotation rods 4. 6, a cleaning cylinder 7 can be detachably installed at the bottom end, and the sides of the two T-shaped frames 1 are provided with mounting holes, and a driving rotary rod 8 is installed in the two mounting holes for common rotation. A driving motor 9 is fixedly provided on the side of one of the T-shaped frames 1, and the output end of the driving motor 9 is fixedly connected to one end of the driving rotary rod 8. The driving rotary rod 8 is connected to a synchronous transmission unit for making the two vertical studs 3 and a plurality of hexagonal rotating rods 4 rotate synchronously. The sides of the two T-shaped frames 1 close to each other are fixedly installed with support plates 10, and the bottoms of the two support plates 10 are both in contact with the top of the riser heat exchanger. The tops of the two T-shaped frames 1 are jointly fixedly installed with a connecting plate 19, and the top of the connecting plate 19 is fixed with a lifting ring 20.

[0024] With the above structure, when in use, the device is lifted by the lifting ring 20 and placed on the top of the vertical tube heat exchanger, and the position of the device is adjusted so that the multiple cleaning cylinders 7 are respectively aligned with the center of the multiple pipes, and then the driving motor 9 is started. The operation of the driving motor 9 will drive the driving rotating rod 8 to rotate. The rotation of the driving rotating rod 8 will drive the two vertical studs 3 and the multiple hexagonal rotating rods 4 to rotate synchronously through the synchronous transmission unit. The rotation of the two vertical studs 3 will drive the movable plate 5 to move up and down, and then drive the multiple hollow rotating rods 6 and the multiple cleaning cylinders 7 to move up and down together. In this process, the rotation of the multiple hexagonal rotating rods 4 will drive the multiple hollow rotating rods 6 and the multiple cleaning cylinders 7 to rotate together, so that the multiple cleaning cylinders 7 will automatically clean the inner wall of the pipe of the vertical tube heat exchanger while moving up and down, and during the cleaning process, the cleaning cylinder 7 will not shake in the pipe, the cleaning effect is good, and the use is simple and convenient, and the practicality is good.

[0025] like Figure 1 As shown, the synchronous transmission unit includes multiple first bevel gears 11 fixedly mounted on the driving rod 8. Second bevel gears 12 are fixedly mounted on the top ends of the two vertical studs 3 and the multiple hexagonal rotating rods 4. The multiple first bevel gears 11 are respectively meshed with the multiple second bevel gears 12. The advantage of this arrangement is that when the driving rod 8 is rotated, the multiple first bevel gears 11 are driven to rotate. The rotation of the multiple first bevel gears 11 drives the multiple second bevel gears 12 to rotate together, thereby driving the two vertical studs 3 and the multiple hexagonal rotating rods 4 to rotate synchronously, achieving the effect of synchronous transmission.

[0026] like Figure 3 As shown, the sides of the two T-shaped frames 1 are each provided with a horizontal screw hole, in which a horizontal stud 13 is threadedly installed. A clamping plate 14 is rotatably installed at the end of the two horizontal studs 13 that is close to each other. A control dial 15 is fixedly installed at the other end of the two horizontal studs 13, and a horizontal guide unit is installed on the two clamping plates 14. The advantage of this arrangement is that when the control dial 15 is rotated, the horizontal studs 13 are driven to rotate together. At this time, under the action of the horizontal screw hole, the horizontal studs 13 will move horizontally while rotating, and then drive the clamping plates 14 to move horizontally together, so that the device can be clamped and fixed on the vertical tube heat exchanger, effectively preventing the device from shaking and tipping over during cleaning, and improving stability during use.

[0027] like Figure 3 As shown, the horizontal guide unit includes two horizontal guide rods 16 fixedly mounted on the sides of the clamping plate 14. Two horizontal slide holes are provided on the sides of the T-shaped frame 1, and the two horizontal guide rods 16 are slidably mounted in the two horizontal slide holes. The advantage of this arrangement is that the horizontal guide rods 16 and the horizontal slide holes ensure that the clamping plate 14 can only move horizontally and will not rotate with the horizontal studs 13, thus providing a horizontal guide function.

[0028] like Figure 4 As shown, a mounting plate 17 is fixedly mounted on the bottom end of the hollow rotating rod 6. Multiple mounting holes are evenly formed on the top of the mounting plate 17. Fastening bolts 18 are slidably mounted in each of the mounting holes. Multiple fastening screw holes are evenly formed on the top of the cleaning barrel 7. The bottom ends of the fastening bolts 18 are threadedly mounted in each of the fastening screw holes. This arrangement has the advantage that when the fastening bolts 18 are rotated, the cleaning barrel 7 can be fixed or loosened with the cooperation of the fastening screw holes, thereby facilitating the disassembly and replacement of the cleaning barrel 7.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
