[0016] (Three) beneficial effects

[0017] The application provides a distillation device for ethanol reagent purification.

[0018] 1. The distillation device for ethanol reagent purification, when leakage occurs, ethanol vapor stays in the inside of the sealing sleeve, so that the operator has enough time to stop the operation of the purification equipment and subsequent repair, effectively preventing dangerous situations and improving the safety in use.

[0019] 2. The distillation device for purifying ethanol reagents, through the setting of the alarm component, under normal conditions, adjusts the air pressure in the sealing sleeve to less than the standard atmospheric pressure through the initial air pressure regulating component. At this time, the air pressure in the second shell is greater than the air pressure in the sealing sleeve, causing the elastic films in the strip openings on both sides to bulge outward. At this time, the iron sheet bulges outward synchronously, so that the iron sheet has no contact with the first contact piece, the second contact piece, the third contact piece, and the fourth contact piece. When a leak occurs in the sealing sleeve, the air pressure in the sealing sleeve returns to the standard atmospheric pressure, causing the elastic films on both sides to return to a horizontal state. At this time, the iron sheet on the right side is in contact with the first contact piece and the second contact piece, so that a path is formed for the first signal generator, and the first signal generator generates a signal. To the single-chip microcomputer, the single-chip microcomputer controls the first alarm light to light up and the buzzer to sound. When there is a gas leak at the connection between the distillation box and the first steam duct, the air pressure in the sealing sleeve is greater than the standard atmospheric pressure, causing the elastic film on the left to sink inward until the iron sheet fits with the third contact piece and the fourth contact piece, so that the second signal generator forms a passage. The second signal generator generates a signal to the single-chip microcomputer, and the single-chip microcomputer controls the second alarm light to light up. It can not only know whether there is a leak inside, but also directly judge whether the leak is from the sealing sleeve or between the distillation box and the first steam duct according to the lighting of the first alarm light and the second alarm light, which is convenient for subsequent maintenance, greatly facilitates the operation of the repairer, and is more convenient to use.
