[0027] The liquid level meter 4 is an ultrasonic liquid level meter.

[0028] In this embodiment, a stirring mechanism is provided inside the distillation tank body 2, and the stirring mechanism includes a driving motor 5, which is fixedly mounted on the top of the distillation tank body 2. A spline shaft 6 is fixedly mounted on the output shaft of the driving motor 5, and a rotating shaft 7 is fixedly connected to the lower end of the spline shaft 6. The spline shaft 6 and the rotating shaft 7 extend to the inside of the distillation tank body 2, and a stirring blade 8 is fixedly connected to the outer wall of the rotating shaft 7. By starting the driving motor 5, the spline shaft 6 is driven to rotate, and the rotating shaft 7 is driven to rotate, thereby driving the stirring blade 8 to rotate. The stirring blade 8 can be used to evenly stir the raw materials inside the distillation tank body 2, so that they are evenly heated, thereby improving the distillation efficiency.

[0029] It should be noted that the number of the stirring blades 8 is set to four, and the four stirring blades 8 are symmetrically distributed on the left and right sides of the stirring blade 8 .

[0030] In this embodiment, a defoaming component is provided on the outside of the spline shaft 6, and the defoaming component includes a sleeve 9, and a steel wire strip 10 is fixedly connected to the left and right sides of the sleeve 9. A plurality of sharp cones 11 are equidistantly provided on the outer wall of the steel wire strip 10, wherein the sleeve 9 is sleeved on the outer wall of the spline shaft 6, and the inner wall of the sleeve 9 is matched with the outer wall of the spline shaft 6. When the spline shaft 6 rotates, the sleeve 9 can be driven to rotate synchronously, thereby driving the steel wire strip 10 to rotate, and the steel wire strip 10 can be used to break the foam on the upper surface of the liquid, and the set sharp cones 11 can improve the foam breaking effect of the steel wire strip 10, so that the foam is automatically broken while the operation is in progress, and the foam can be prevented from overflowing without using a defoaming agent, thereby saving costs for the enterprise and improving production efficiency.

The annular plate 15 slides with the inner side of the annular groove, so that the sleeve 9 can rotate along the inner side of the annular sleeve 14 through the annular plate 15.
