Description
Technical Field
The utility model belongs to the technical field of quercetin recrystallization processing, and particularly relates to liquid phase suction filtration equipment for recrystallization.
Background
Recrystallization is a process in which a substance is dissolved in a solvent or melted and then recrystallized from the solution or melt. Recrystallization may allow purification of impure materials or separation of materials mixed together from one another. The solid material can be purified by recrystallization. Some metals or alloys may be recrystallized to refine the grain or to alter the crystallization of the crystal, thereby altering its properties.
In the recrystallization process, the solubility of the solid mixture in the solvent is closely related to temperature. Generally at elevated temperatures, the solubility increases. When the solution is saturated in a hot solvent, the solubility decreases upon cooling, and the solution becomes supersaturated to precipitate crystals. The solvent has different solubilities for the purified substance and impurities, so that the purified substance can be separated out. And the impurities are fully or mostly remained in the solution (if the solubility in the solvent is extremely small, the solution is prepared into a saturated solution and then filtered and removed), thereby achieving the aim of purification.
In the processing of quercetin, recrystallization is an indispensable step, and in the course of recrystallization, the following steps are generally included: (1) selecting a suitable solvent to prepare a hot saturated solution; (2) removing insoluble impurities; (3) cooling, crystallizing, filtering and removing; and (4) washing and drying to remove attachments and solvents. The following disadvantages still exist in the suction filtration process:
1. in the traditional recrystallization process, the temperature is mostly adopted to precipitate crystals in the solution, the liquid phase in the solution is pumped out after the crystals are precipitated, in the liquid pumping process, the internal solution is pumped out but the crystals are not pumped out in the pumping mode, so that the quality of the finally precipitated crystals is ensured, but the conventional pumping mode is far less efficient and is easy to block a filtering part, so that the pumping efficiency is greatly reduced, and the pumping area is usually smaller;
2. the suction filtration is to extract liquid phase and filter, but in the recrystallization process, the solution in the crystallization tank can be separated out to a certain degree, and the crystallization is realized completely depending on the cooling of the crystallization tank, so the temperature of the solution in the middle of the crystallization tank can be insufficient, the crystals can not be completely separated out, the solution still contains the required substances, and waste is caused, so the suction filtration operation can be performed after the crystallization is fully cooled.
