In order to clean these impurities, a device for cleaning the inner wall of the distillation kettle is needed to prevent the residual impurities from affecting the next use. The cleaning device provided by the utility model is convenient for disassembly and replacement of the cleaning brush 13, so that when the cleaning brush 13 is damaged later, it can be quickly replaced, which is more convenient.

[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a device for cleaning the inner wall of a distillation kettle, comprising a mounting frame 1, a telescopic rod 2 is fixed to the top of the mounting frame 1, a top plate 3 is fixed to the telescopic end of the telescopic rod 2, a rotating column 5 is rotatably connected to the bottom end of the top plate 3, a motor 4 is fixed to the top of the top plate 3, an output end of the motor 4 passes through the top plate 3 and is fixed to the rotating column 5, a first connecting shell 8 is fixed to the outer wall of the rotating column 5, a second connecting shell 9 is fixed to the bottom end of the rotating column 5, first plugging rods 10 are slidably connected to the inner walls of both ends of the first connecting shell 8, second plugging rods 11 are slidably connected to the inner walls of both ends of the second connecting shell 9, and the first plugging rod 10 and the second plugging rod 11 are located at the same end. A connecting piece 12 is fixed between 11, and a slot is provided at the end of the connecting piece 12 away from the rotating column 5, in which a plug-in 14 is inserted, and a cleaning brush 13 is fixed at the end of the plug-in 14, and multiple connecting grooves 15 are provided on the outer walls of both sides of the plug-in 14. The connecting piece 12 is located on both sides of the slot and has installation grooves inside, and a moving plate 17 is slidably connected in the installation groove, and a plug-in column 18 is fixed on the side of the moving plate 17 close to the slot, and the plug-in column 18 is inserted into the connecting groove 15, and a moving column 16 is fixed on the other side of the moving plate 17. After the moving column 16 passes through the connecting piece 12, a pull plate 20 is fixed at its end, and a spring 19 is fixed between the other side of the moving plate 17 and the installation groove.

[0021] It should be noted that by pulling the pull plate 20 outward, the movable column 16 drives the movable plate 17 and the plug 18 to move outward, so that the plug 18 is no longer located in the slot, so that the plug 14 at one end of the cleaning brush 13 can be inserted into the slot, and then the pull plate 20 is released, and the spring 19 drives the movable column 16, the movable plate 17 and the plug 18 to move inward, so that the plug 18 can be inserted into the connecting groove 15, and the plug 14 is limited, thereby fixing the cleaning brush 13, so that when the cleaning brush 13 is damaged later, it is convenient to replace the cleaning brush 13.

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, two fixing plates are fixed to the inner wall of the second connecting shell 9, and a double-headed screw 21 is rotatably connected between the two fixing plates. The second plug rod 11 is screwed to the outer walls of both ends of the double-headed screw 21. A first gear 22 is fixed to the outer wall of the double-headed screw 21, and a rotating rod is rotatably connected to one side of the second connecting shell 9. After the rotating rod passes through the second connecting shell 9, a second gear 23 is fixed to the outer wall of the rotating rod, and the second gear 23 is meshed with the first gear 22. A first connecting block is fixed to the outer wall of the first plug rod 10, and the first connecting block slides in the first connecting shell 8.

A push rod 6 is installed at one end of the mounting frame 1, and a plurality of universal wheels 7 are fixed to the bottom end of the mounting frame 1. A controller is installed at the top of the mounting frame 1.

[0023] It should be noted that by rotating the rotating rod, the rotating rod drives the second gear 23 to rotate, the rotation of the second gear 23 drives the first gear 22 to rotate, and the rotation of the first gear 22 drives the double-headed screw 21 to rotate, which can drive the two second plug rods 11 to move to both ends, thereby causing the connecting piece 12 and the cleaning brush 13 to move to both ends, and when the connecting piece 12 moves, the first plug rod 10 also moves to both ends, and finally the cleaning brush 13 contacts the inner wall of the distillation kettle, which is convenient for cleaning the inner wall of the distillation kettle.

[0024] Working principle: When the cleaning brush 13 needs to be disassembled, the pull plate 20 is pulled outward, so that the movable column 16 drives the movable plate 17 and the plug-in column 18 to move outward, so that the plug-in column 18 is no longer located in the slot, and the cleaning brush 13 can be taken out. Subsequently, the plug-in 14 at one end of the replaced cleaning brush 13 is inserted into the slot, and the pull plate 20 is released. The spring 19 drives the movable column 16, the movable plate 17 and the plug-in column 18 to move inward, so that the plug-in column 18 can be inserted into the connecting groove 15, and the plug-in 14 is limited, thereby fixing the cleaning brush 13.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
