A sliding frame 16 is provided on the outer side of the lead screw 15 and the two guide rods 13. Three connecting frames 17 are provided at the bottom of the sliding frame 16. The bottom of the connecting frames 17 is connected to the cylindrical cover 11. The stirring assembly includes a second servo motor 18, and the output end of the second servo motor 18 movably passes through the cylindrical cover 11. A stirring shaft 19 is connected to the base 1. Multiple stirring blades 20 are evenly distributed on the outer side of the stirring shaft 19. A feeding port 21 is provided on the top of the processing tank 2. A heating wire 22 is sleeved on the outer side of the inner liner 3. One end of the heating wire 22 passes through the base 1 and is connected to an electric heating controller 23. A control valve 24 is provided on the outer side of the processing tank 2.

Then, the control valve 24 is opened to allow the mixture to flow from the conveying pipe 25 into the separation chamber 26. The mixture is separated by the separation membrane 27, and the purified dichloroacetaldehyde is discharged from the discharge pipe 28. Finally, the first servo motor 14 is started to drive the lead screw 15 to rotate, causing the sliding frame 16 to slide the cylinder cover 11 and the stirring assembly upward, which facilitates the maintenance of the device.
