High-precision reduced-pressure distillation apparatus

Abstract

The invention provides a high-precision decompression distillation device, which includes an annular sealing ring, a sealing baffle, a sealing cover, a connecting rod, an exhaust pipe, an inclined pipe, a tee pipe, a rotating blade, a condensation pipe, a waterproof motor and a filter screen. The annular sealing ring is assembled on the sealing baffle, the connecting rod is installed on the sealing baffle, the annular sealing ring is assembled on the connecting rod, the sealing cover is connected to the upper end of the sealing baffle, this design can be stirred, The right end of the exhaust pipe is connected to a three-way pipe, the lower end of the three-way pipe is provided with an inclined pipe, the right end of the three-way pipe is equipped with a condensation pipe, and a rotating blade, a waterproof motor and a filter screen are installed inside the three-way pipe. The waterproof motor is connected with the rotating blade through the filter net. This design can be used for filtering and circular distillation. The invention is easy to use and easy to operate, and can be stirred, filtered and circularly distilled.

Description

technical field [0001] The invention is a high-precision vacuum distillation device, which belongs to the technical field of distillation. Background technique [0002] Distillation is a thermodynamic separation process. It utilizes the different boiling points of the components in the mixed liquid or liquid-solid system to evaporate the low-boiling components and then condense them to separate the entire components. There are two types of evaporation and condensation. A union of unit operations. Compared with other separation methods, such as extraction, filtration and crystallization, its advantage is that it does not need to use other solvents other than the system components, so as to ensure that no new impurities will be introduced. [0003] When the existing high-precision vacuum distillation device is performing distillation work, because there is no stirring device, the distillation time is too long, which increases the damage to the energy source and prolongs the w...

Problems solved by technology

[0003] When the existing high-precision vacuum distillation device is performing distillation work, because there is no stirring device, the distillation time is too long, which increases the damage to the energy source and prolongs the working time of the personnel. The existing high-precision vacuum distillation When the distillation device collects the distilled liquid, it usually does not filter again, resulting in low precision of the obtained distilled liquid, which reduces the use effect, and at the same time, it cannot perform circular distillation, and the scope of application is low.
