S2, sealing: accommodating chamber is sealed using the sealing structure formed between ring type seal (206) and annular seal groove (106)
It closes, and is pulled down interlayer (108) using the negative pressure state of upper space (102), make to form negative pressure state in negative pressure trough (107),
Capping (2) is further attracted;
S3, it vacuumizes: further being vacuumized the accommodating chamber of upper space (102) and distillation still (1) using external vacuum pump,
Reduce the moisture boiling point in butanediol;
S4, heating: it is passed through steam into heating tube (3) using steam-out (SO) pipeline, butanediol is heated, in butanediol
Moisture is evaporated by thermal acceleration;
S5, stirring: steam flows and intra vane (402) is pushed to rotate, and the intra vane (402) utilizes rotary clip (401) band
Dynamic outer leafs (403) rotation, outer leafs (403) push butanediol flowing, improve being heated evenly property of butanediol and further adopt
It can push butanediol therebetween is opposite to spring up with the outer leafs (403) that a pair relatively rotates, improve mixed flow efficiency and effect;
S6, supervision: moisture is mixed through ventilative dottle pin (203) with anhydrous cupric sulfate (204), and anhydrous cupric sulfate (204) is met water and become
For blue cupric sulfate pentahydrate, becoming blue degree by transparent sealant (205) observation anhydrous cupric sulfate (204) can be appreciated that distillation effect
Fruit and progress;
S7, adjustment: anhydrous cupric sulfate (204) powder is embedded in the mode in ventilative dottle pin (203), the openable sealant in midway
(205) the ventilative dottle pin (203) containing anhydrous cupric sulfate (204) more renewed guarantees the ventilative absorption of dottle pin (203) to moisture
Effect, it is accurate to understand distillation situation.
