[0028] The feed pipe 3 is connected to the side wall of the distillation tower body 1 to facilitate the transportation of liquid raw materials from the outside into the distillation tower body 1;

[0029] The discharge port 4 is connected to the upper wall of the distillation tower body 1 to facilitate the outflow of the distillation gas in the distillation tower body 1;

[0030] The reflux pipe 21 is connected to the side wall of the distillation tower body 1, so as to facilitate the external reboiler to vaporize the liquid raw material and transport it to the distillation tower body 1;

[0031] The sewage outlet 5 is connected to the lower wall of the distillation tower body 1, so as to facilitate the discharge of impurities or pollutants in the distillation tower body 1 to the outside of the distillation tower body 1;

[0032] The plates 2 are arranged in a staggered manner in the distillation tower body 1. The plates 2 are welded in the distillation tower body 1 so that the liquid raw material can flow downward from each plate and contact with the steam below the distillation tower body 1.

[0033] The rotating shaft 6 is arranged in the distillation tower body 1 and penetrates the tower plate 2. The rotating shaft 6 is rotatably installed in the distillation tower body 1;

[0034] There are several n-shaped frames 7, all of which are connected to the rotating shaft 6. The n-shaped frames 7 are welded to the rotating shaft 6 so that the rotating shaft 6 can drive the n-shaped frames 7 to rotate;

[0035] The bristles 8 are arranged on the surface of the n-shaped frame 7 and are in contact with the inner wall of the distillation tower body 1 and the surface of the tower plate 2. The bristles 8 are fixedly installed on the surface of the n-shaped frame 7. When the rotating shaft 6 drives the n-shaped frame 7 to rotate, the bristles 8 brush and clean the inner wall of the distillation tower body 1 and the surface of the tower plate 2.

[0036] Specifically, an annular tube 9 is provided on the upper wall of the distillation tower body 1, and two pairs of connecting tubes 10 are connected to the annular tube 9. The connecting tubes 10 are fixedly connected to the annular tube 9, and the lower ends of the connecting tubes 10 are connected to a plurality of water outlet pipes 12. A water inlet hole 13 connected to the water outlet pipe 12 is formed on the upper wall of the distillation tower body 1, and an electric valve 14 is installed on the water outlet pipe 12.

[0037] Specifically, a water pump 15 and a box body 16 are installed on the side wall of the distillation tower body 1. The water inlet end of the water pump 15 is connected to an external water source. The water pump 15 and the box body 16 are fixedly installed on the side wall of the distillation tower body 1. The water outlet end of the water pump 15 passes through the lower wall of the box body 16. The annular tube 9 is connected to a delivery pipe 17. The end of the delivery pipe 17 away from the annular tube 9 passes through the upper wall of the box body 16. The water pump 15 pumps external water into the box body 16, and then the delivery pipe 17 delivers it to the annular tube 9 and the connecting pipe 10. The staff opens the electric valve 14 to allow the water in the connecting pipe 10 to flow from the outlet pipe 12 and the water inlet hole 13 to the distillation tower body 1, so that the interior of the distillation tower body 1 can be cleaned conveniently.

[0038] Specifically, a filter frame 18 is provided inside the box body 16, and the inner wall of the box body 16 is symmetrically welded with limit blocks. The outer wall of the filter frame 18 is formed with a sliding opening that is slidably connected to the conveying limit block, so that the filter frame 18 can be easily disassembled. A filter screen 19 is provided inside the filter frame 18, and the filter screen 19 is fixedly installed in the filter frame 18, so that the water at the water outlet of the water pump 15 can be filtered to prevent impurities from entering the distillation tower body 1. A sealing door is hinged on the box body 16, and the sealing door can seal the box body 16 to prevent water leakage. At the same time, it is also convenient for the staff to take out the filter frame 18 for cleaning.

[0039] Specifically, a reducer 20 is installed on the upper wall of the distillation tower body 1. The reducer 20 is fixedly installed on the upper wall of the distillation tower body 1. The output end of the reducer 20 is connected to one end of the rotating shaft 6. The upper end of the reducer 20 is connected to a driving member 11. The driving member 11 is a motor and is fixedly installed on the upper end surface of the reducer 20 and is relatively fixed to the reducer 20. The output end of the driving member 11 is connected to the input end of the reducer 20. The reducer 20 can reduce the rotation speed of the driving member 11 and drive the rotating shaft 6 to rotate.

[0040] Working principle: After the distillation tower body 1 has finished distilling the raw materials, raw material impurities remain on the inner wall of the distillation tower body 1 and the surface of the tower plate 2. At this time, the staff starts the water pump 15 to pump the external water source into the box 16. At this time, the filter screen 19 filters the water source and then transports it to the annular pipe 9 and the connecting pipe 10 through the delivery pipe 17. At this time, the staff opens the electric valve 14 to allow water to flow from the outlet pipe 12 and the water inlet hole 13 into the distillation tower body 1. At this time, the staff starts the driving member 11 to drive the driving member 11 to drive the driving member 11. The output end of the moving member 11 drives the input end of the reducer 20 to rotate, and the reducer 20 reduces the speed of the driving member 11, and then the output end of the reducer 20 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the n-shaped frame 7, and the rotation of the n-shaped frame 7 drives the bristles 8 to brush and clean the inner wall surface of the distillation tower body 1 and the surface of the tower plate 2. With the cooperation of the bristles 8 and water, the inner wall surface of the distillation tower body 1 and the surface of the tower plate 2 are cleaned, and at the same time, the sewage generated after cleaning is discharged from the sewage outlet 5, which brings convenience to people.
