Abstract

The invention discloses a bismaleimide continuous recrystallization device and a use method thereof. The device comprises a dissolving kettle for dissolving a recrystallization material into a recrystallization liquid; a recrystallization kettle used for realizing recrystallization, connected with a recrystallization liquid discharge port of the dissolving kettle through a solution conveying pipe, and provided with a recrystallization liquid discharge port and a recrystallization material discharge port; a solvent buffer tank connected with the recrystallization liquid discharge port of the recrystallization kettle through a solution conveying pipe, and used for collecting, controlling the temperature and retreating the recrystallization liquid, and returning the recrystallization liquid to the dissolving kettle through the solution conveying pipe under the action of a metering pump. The continuous recrystallization device is reasonable in design, ingenious in structure, used for continuous recrystallization of bismaleimide, easy to use, high in crystallization efficiency and smooth in operation, the solvent can be recycled, the working efficiency of workers is high, the labor intensity is low, and automatic control is convenient.

Description

technical field [0001] The invention relates to the field of bismaleimide recrystallization methods, in particular to a bismaleimide continuous recrystallization device and a use method. Background technique [0002] The existing industrial-grade bismaleimide product has relatively low purity, and if a product with higher purity is required, it needs to be recrystallized in a recrystallization kettle. The traditional recrystallization kettle operation process is intermittent operation, the disadvantage is that the material is not continuous, the material is easy to block, the circulation is not smooth, the recrystallization solvent cannot be recycled, the operation process needs to be intermittently operated, it consumes a lot of manpower and time, and the work efficiency is low. Contents of the invention [0003] Therefore, in order to solve the above-mentioned deficiencies, the present invention provides a kind of reasonable design here, ingenious structure, the device f...
