Description

Technical Field

[0001] The utility model relates to the technical field of solvent recovery, in particular to a vacuum unit for desolventizing and solvent recovery processes. Background Art

[0002] Desolventization refers to a chemical reagent used to remove and separate solvents contained in certain substances. In some scientific experiments, in order to separate one or several organic compounds from a mixture, desolventization is required to separate them from other substances. In laboratories or industrial production, desolventization is also widely used. Solvent is a liquid that can dissolve solid, liquid or gaseous solutes. The most common solvent in daily life is water, and the so-called organic solvent is an organic compound containing carbon atoms. Solvents usually have a relatively low boiling point and are easy to volatilize.

[0003] However, it still has some disadvantages. For example, during the recycling process, the solvent is easily attached to the surface of the machine, causing corrosion to the inside of the machine and affecting its service life. During recycling, due to the single recycling method, part of the solvent decomposes and is lost, thus affecting the recovery rate and quality of the solvent.

[0004] In order to solve the above problems, the present application proposes a vacuum unit for desolventizing and solvent recovery processes. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model has good sealing performance through the sealing ring, which can avoid the volatilization of the solvent. Through the heating component above the fixed base, the boiling point difference between the solvent and the garbage is utilized to evaporate the solvent after heating by the heating component.

At the same time, the impurities attached to the inner wall of the recovery barrel after evaporation can be cleaned by a cleaning ring, so as to avoid the impurities adhering to the inner wall of the recovery barrel and causing rust on the inner wall of the recovery barrel.
