Description

Technical Field

[0001] The utility model relates to the technical field of recrystallization, in particular to a recrystallization device. Background Art

[0002] Recrystallization is the process of dissolving crystals in a solvent or melting them and then re-crystallizing them from the solution or melt. Recrystallization can purify impure substances or separate mixed substances from each other.

[0003] Sodium benzenesulfinate is white crystal or white powder, with a melting point of 300℃. It is stable at room temperature and pressure, avoids contact with oxides, and is easily oxidized by light. It is used in medicine, electroplating industry and synthesis of photosensitive materials; polymer adhesion enhancer, plasticizer, used for plasticization and modification of polyamide, epoxy resin, phenolic resin, used in ink, adhesive, nail polish, coating; used in food, feed preservatives, etc.

[0004] The utility model patent with the publication (announcement) number: CN220257210U solves the problem that the current recrystallization method is inefficient in purifying sodium benzenesulfinate by a recrystallization method in the current production. The utility model patent adopts a solvent and sodium benzenesulfinate to be added to a crystallization kettle, and the stirring motor and the stirring fan blade group are lifted and lowered simultaneously by the extension and retraction of the electric telescopic rod to accelerate the dissolution of sodium benzenesulfinate, and finally quickly form a saturated sodium benzenesulfinate solution. A filter barrel is provided inside the crystallization kettle, and a heating ring is installed in the filter barrel. The heating ring is installed to heat the solution and finally the solvent is boiled and distilled. As the solvent decreases, sodium benzenesulfinate crystals will precipitate from the saturated solution. The filter barrel will be lifted out of the crystallization kettle by the extension of the hydraulic cylinder, and the filter barrel will be crystallized and dumped by the servo motor to complete the recrystallization and extraction of sodium benzenesulfinate. However, in actual use, the precipitated sodium benzenesulfinate crystals will adhere to the inner wall of the filter barrel and cannot be discharged by dumping. Therefore, it is necessary to design and transform the recrystallization device to effectively prevent the phenomenon of inconvenience in unloading. Utility Model Content
