Scraper type molecular distillation device

Abstract

The invention discloses a scraper type molecular distillation device, which comprises a body and a condenser; the body is provided with a partition, the partition is disc-shaped, and the partition divides the interior of the body into an upper cavity and a lower cavity; Two strip-shaped scrapers are installed symmetrically on the left and right sides of the bottom of the partition. The scraper is composed of a mounting plate and a number of scraping blocks, and the scraping blocks are fixed on the outer surface of the scraper through the mounting plate; The scrapers are equidistantly arranged, and the scrapers are close to the inner wall of the body, and the corresponding positions of each scraper are provided with through holes that can communicate with each other; the condenser is fixedly installed inside the lower cavity, and the condenser It consists of a filter screen and a condensation funnel. In the present invention, a scraper with several scrapers is arranged on the scraper, and each scraper is provided with a through hole that can communicate with each other at the corresponding position, so as to reduce the flow velocity of the mixed solution and make the mixed solution evenly spread on the device. On the inner wall, the distillation effect is improved.

Description

technical field [0001] The invention relates to a distillation device, in particular to a scraper type molecular distillation device. Background technique [0002] The molecular distillation process is a special liquid-liquid separation technology. Compared with the traditional separation technology, it has the advantages of low process operating temperature, high vacuum degree, short heating time, and high separation efficiency. It is especially suitable for high boiling point, heat sensitivity, and easy oxidation. The advantages of material separation. [0003] The existing scraper-type molecular distillation device adopts an integrated structure. There is a certain gap between the scraper and the inner wall of the device. After the mixed liquid flows into the gap, the scraper spreads the mixed liquid in the gap on the inner wall of the device, but when the mixed liquid flows into the gap , it is easy to directly flow to the bottom of the inner wall of the device, and the...

[0003] The existing scraper-type molecular distillation device adopts an integrated structure. There is a certain gap between the scraper and the inner wall of the device. After the mixed liquid flows into the gap, the scraper spreads the mixed liquid in the gap on the inner wall of the device, but when the mixed liquid flows into the gap , it is easy to flow directly to the bottom of the inner wall of the device, and then flow out from the liquid outlet, which not only causes waste of the mixed liquid, but also causes the uneven spreading of the mixed liquid on the inner wall surface of the device, reducing the distillation effect
