The walls are distributed at equal intervals, and two groups of rotating shafts 12 are arranged inside the concentration chamber 3. The two groups of stirring shafts 13 are staggered inside the concentration chamber 3. When in use, sodium formate solution is added to the inside of the concentration chamber 3 through the feed port 4, and then the heating block 6 is started to heat the inside of the heating block 6, and then the sodium formate solution is evaporated and concentrated, and the steam is discharged from the gas outlet 7. At this time, the first servo motor 9 is started to drive the pulley structure 8 to rotate. Therefore, under the transmission of the pulley structure 8, the pulley structure 8 is used to drive the first bevel gear 10 to rotate. Since the first bevel gear 10 and the second bevel gear 11 are meshed with each other, the second bevel gear 11 is used to drive the rotating shaft 12 to rotate, and then the stirring shaft 13 is driven to rotate, and the sodium formate solution is stirred, so that the evaporation and concentration effect of the sodium formate solution is better, thereby greatly improving the practicality of the device when in use.
