A shaft tube 30 is provided, and both ends of the shaft tube 30 are rotatably connected to the end shaft 1 202 and the end shaft 203 through a sealing shaft, and the interior of the shaft tube 30 is a hollow structure. A plurality of high-pressure nozzles 301 are provided at the bottom of the shaft tube 30 along its length direction. One end of the shaft tube 30 passes through the end shaft 1 202 and the outside of the cleaning box 10 and is fixed on the cleaning box 10. A roller brush 40 is provided at an oblique lower part of the drum 20, and the roller brush 40 is installed on the shaft tube 30 through a supporting structure. At the same time, the roller brush 40 is driven by a driving device to rotate axially.

[0022] Furthermore, a positioning block 60 for fixing the shaft tube 30 is also provided on the outside of the cleaning box 10. The shaft tube 30 is positioned firmly by the positioning block 60. The positioning method can be thread locking, snap locking, etc., which are not limited here. After the shaft tube 30 is fixed, it can prevent the drum 20 from rotating when it rotates, so that the high-pressure nozzle 301 can always flush the lower parts in the drum, and at the same time, the roller brush 40 can also brush the lower parts.

[0023] Furthermore, a multi-way connector 302 is provided at one end of the shaft tube 30 located on the outside of the cleaning box 10, and the multi-way connector 302 is externally connected to a tube pump.

During the rotation process, irregular parts will be continuously rolled and turned over, and the shaft tube 30, in cooperation with the tube pump, performs close-range high-pressure washing and flushing of the parts below through the high-pressure nozzle 301, thereby greatly improving the cleaning efficiency of the parts. At the same time, during the flipping process, some parts will alternately move to the oblique upper side of the bottom of the cylinder. At this time, the waterproof motor 402 will drive the roller brush 40 to rotate quickly and continuously brush the parts in contact with it, further accelerating the cleaning efficiency of the parts, which is simple and efficient, saving time and effort. In addition, the high-pressure nozzle 301 can also flush the rotating roller brush 40 to achieve a self-cleaning effect.

[0028] In summary, in the present embodiment, a cleaning device for petrochemical tower internals can be used to guide the parts into the drum 20 by opening and closing the arc door panel 204 and the chamber door 101 during cleaning. During cleaning, the servo motor 50 drives the drum 20 to rotate clockwise through the end shaft (see Figure 3 ), during the rotation process, irregular parts will be constantly rolled and turned over, and the shaft tube 30, with the cooperation of the tube pump, uses the high-pressure nozzle 301 to perform close-range high-pressure washing and flushing on the parts below, thereby greatly improving the cleaning efficiency of the parts. At the same time, during the flipping process, some parts will alternately move to the upper side of the bottom of the tube.
