[0021] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] like Figs. 1-3 As shown, a cleaning device for the inner wall of a furnace tube includes a mounting rod 1, cleaning heads 2 disposed at both ends of the mounting rod 1, and a cleaning brush 3 that can slide along the length of the mounting rod 1. The cleaning heads 2 can slide along the radial direction of the mounting rod 1 to contact the inner wall of the furnace tube. A drive assembly 4 is mounted on the mounting rod 1 to make the cleaning brush 3 slide along the length of the mounting rod 1. Fillers 5 are also mounted on the two cleaning heads 2 to form a sealed storage space between the two cleaning heads 2 and the inner wall of the furnace tube, and the cleaning liquid for cleaning the inner wall of the furnace tube is stored in the sealed storage space.

[0023] When cleaning the inner wall of the furnace tube, the mounting rod 1 is first placed inside the furnace tube, and then the mounting rod 1 is rotated to make the cleaning head 2 clean the inner wall of the furnace tube. After the inner wall of the furnace tube in contact with the cleaning head 2 is cleaned, the mounting rod 1 is rotated to make the filler 5 rotate to the bottom of the inner wall of the furnace tube and seal it in contact with the inner wall of the furnace tube. At this time, a sealed storage space is formed between the two cleaning heads 2 and the inner wall of the furnace tube. The cleaning liquid used to clean the inner wall of the furnace tube is stored in the storage space. The cleaning brush 3 is moved in the opposite direction along the length of the mounting rod 1 by the drive assembly 4 to clean the inner wall of the furnace tube.

[0024] The mounting rod 1 is a hollow rod-shaped structure. The cleaning head 2 is connected to the interior of the mounting rod 1, and the other end of the mounting rod 1 is connected to the air inflation component 6. When the cleaning head 2 needs to slide along the radial direction of the mounting rod 1, different amounts of gas are injected into the mounting rod 1 through the air inflation component 6, thereby causing the cleaning head 2 to slide different distances along the radial direction of the mounting rod 1 until the mounting rod 1 is basically concentric with the inner wall of the furnace tube. At this time, the mounting rod 1 is rotated so that the cleaning head 2 can clean the inner wall of the furnace tube.

[0025] Preferably, two cleaning heads 2 are equipped with solenoid valves 21 facing each other; when the cleaning head 2 contacts the inner wall of the furnace tube, impurities on the inner wall are cleaned. When the solenoid valve 21 is opened, the airflow pushes the impurity box between the two cleaning heads 2. When the filler 5 on the cleaning head 2 is unfolded, the filler 5 abuts against the inner wall of the furnace tube that has been cleaned by the cleaning head 2, so as to avoid impurities abutting against the filler 5 and causing the cleaning liquid to flow out.

[0026] The filling piece 5 is an air bag, which is communicated with the mounting rod 1; when the air bag is filled with gas, the air bag is inflated and contacted with the inner wall of the furnace tube, at this time, the sealed space is formed between the two air bags and the inner wall of the furnace tube, and the cleaning liquid can be filled into the sealed space and stirred on the inner wall of the furnace tube by the cleaning brush 3 to soak and clean.

[0027] Specifically, the cleaning brush 3 comprises a fixed part 31 and a cleaning part 32 sliding in the radial direction of the fixed part 31, and a screw is arranged between the cleaning part 32 and the fixed part 31; before the cleaning brush 3 enters the inner wall of the furnace tube, the cleaning part 32 is fixed at different positions of the fixed part 31 by the screw to clean the inner wall of the furnace tube with different diameters.

[0028] In other embodiments of the present application, an elastic member is arranged between the fixed part 31 and the cleaning part 32, and the elastic force applied to the inner wall of the pipeline by the elastic member is used to clean the pipeline.

[0029] Specifically, the side of the cleaning part 32 in contact with the pipeline is provided with bristles to clean the inner wall of the pipeline.

[0030] In a preferred embodiment of the present application, the driving assembly 4 is a lead screw mechanism, which comprises a lead screw, a lead screw nut and a guide, the mounting rod 1 is the guide, the cleaning brush 3 is installed on the movable end of the cleaning head 2, and a driving motor for driving the lead screw mechanism to run is installed on the lead screw mechanism; the driving motor is rotated to drive the lead screw to rotate and in turn drive the cleaning brush 3 to slide along the length direction of the inner wall of the furnace tube to clean the inner wall of the furnace tube.

[0031] The driving assembly 4 is provided with an annular support frame 41, and the driving assembly 4 rotates in the annular support frame 41; in order to ensure that the cleaning brush 3 can clean the inner wall of the furnace tube more thoroughly, a one-way bearing is arranged between the driving assembly 4 and the support frame 41, and after the driving assembly 4 is rotated by a certain angle, the driving assembly 4 and the support frame 41 can remain relatively stationary and cannot rotate relatively.

[0032] Working principle:

[0033] When the pipeline is cleaned, the pipeline is contacted with the filling piece 5 by the cleaning head 2, then the pipeline is filled by the filling piece 5, the pipeline is sealed between the two filling pieces 5, the cleaning liquid is poured between the two filling pieces 5, at this time the cleaning liquid is stored between the two filling pieces 5, then the cleaning brush 3 is driven by the driving assembly 4 to slide between the filling pieces 5 to clean the pipeline, the cleaning brush 3 is rotated by the driving assembly 4 to clean the pipeline more completely, the cleaning liquid can be stored in the pipeline for a long time, the impurities on the inner wall of the pipeline can be soaked to clean the pipeline more completely, the filling piece 5 near the outlet side of the pipeline is separated from the pipeline, the cleaning liquid after cleaning flows out of the pipeline outlet, and the impurities after cleaning are taken out of the pipeline, finally the driving assembly 4 is moved out of the pipeline, and the remaining impurities are taken out of the pipeline by another cleaning head 2, and the impurities in the pipeline do not need to be treated again.

[0034] Although the embodiments of the utility model have been shown and described above, it can be understood that the above-mentioned embodiments are exemplary, and cannot be understood as the limitation of the utility model, and the ordinary skilled in the art can change, modify, replace and transform the above-mentioned embodiments within the scope of the utility model.
