[0044] During use, since in actual applications, the thickness of impurities on the inner wall of the reactor tower may be uneven, thick in some places and thin in others, if the length of the cleaning brush 29 is fixed, it may not be able to effectively clean impurities in all areas. Specifically, if the impurities in a certain area are thicker, the user can pull the hanging ear 35 to move the adjustment seat 34, thereby reducing the extended length of the cleaning brush 29 in the area. In this way, the cleaning brush 29 can contact and clean the outer wall of the impurities, and then gradually increase the extended length to achieve more effective cleaning. On the contrary, if the impurities in a certain area are thinner, the user can increase the length of the cleaning brush 29 accordingly. The extended length allows the cleaning brush 29 to contact impurities. The adjustable cleaning brush 29 design enables the cleaning device to adapt to impurities of different thicknesses, thereby improving cleaning efficiency and effectiveness. When the adjustment seat 34 moves, the set slide bar 43 correspondingly slides continuously in the slide groove 40, providing guidance and support for the movement of the adjustment seat 34, thereby improving the smoothness and directionality of the movement of the adjustment seat 34. A number of evenly distributed adjustment holes 44 are opened to allow for a variety of distance adjustments, thereby improving practicality. The setting of the spring 41 allows the limit rod 38 to be connected to the stirring rod 28 during adjustment, thereby avoiding the loss of the limit rod 38.

[0045] In actual use, when the inner wall of the tower kettle needs to be cleaned, the stud bolts on the upper plate ring 31 and the lower plate ring 32 need to be removed first, thereby releasing the connection between the cover plate 14 and the kettle tower body 6, and then by starting to drive the first motor 1, the output end of the first motor 1 will drive the first sprocket 19 to rotate, and then under the transmission action of the chain 20, the second sprocket 21 will be driven to rotate, and then the rotating drum 22 will be driven to rotate, so that the threaded rod 18 screwed with the rotating drum 22 can be raised, thereby driving the connecting plate 15, the bottom drum 24 and the cover plate 14 to rise, so as to realize the extraction of the rotating shaft 27 from the inside of the kettle tower, and the staff can operate the stirring rod 28 on the rotating shaft 27 by climbing the climbing frame 8 to the handrail 13. Specifically: at this time, the adjusting seat 34 is located at the innermost part of the inner groove 36, and the cleaning brush 29 is located in the inner groove 36. By removing the nut 37 and then pulling the firmware 42, the limiting rod 38 will be driven to be extracted from the through hole 39. At this time, the spring 41 will be stressed Stretch and store elastic potential energy, and pull the hanging ear 35 to drive the adjustment seat 34 to move, so as to control the extension length of the cleaning brush 29. Since the thickness of impurities on the inner wall of the reactor tower is different in actual conditions, the length of the cleaning brush 29 at different positions can be adjusted according to actual needs to achieve more effective cleaning of impurities. After adjustment, the appropriate adjustment hole 44 and the through hole 39 are matched. At this time, the pulling force on the firmware 42 is cancelled.
