Continuous crystalizer

Abstract

The invention discloses a continuous crystallizer, which is characterized in that: the continuous crystallizer comprises an upper end socket 1, an outer barrel body 2, a lower conical body 3 and a lower end socket 10, wherein an inner conical body 4 is arranged in the outer barrel body 2 at a part which is close to the connection part of the inner side of the outer barrel body 2 and the upper end socket 1, and the lower edge of the inner conical body 4 is connected with an inner barrel body 5; a guide cylinder 7 is arranged in the inner conical body 4 and the inner barrel body 5; an upward pushing-type stirrer 6 is arranged in the guide cylinder 7; an external recirculated material outlet 8 is arranged below the connection part of the outer barrel body 2 and the inner conical body 4, an external recirculated material inlet 9 is arranged at the central part of the lower end socket 10 and is provided with a sleeve 12, and the sleeve 12 extends into the inner part of the guide cylinder 7; and the lower end socket 10 is also provided with a crystal mush outlet 11. The invention provides the continuous crystallizer which is used for the cold crystallization process of chemical products, can realize continuous crystallization, and improves the production efficiency and product quality.

Description

technical field [0001] The invention belongs to special chemical equipment, and in particular relates to a continuous crystallizer used in the cold crystallization process of chemical products, which can realize continuous crystallization and improve production efficiency and product quality. Background technique [0002] Existing chemical products generally adopt single-pot batch operation during cold precipitation and crystallization. The heat transfer efficiency of the equipment is low, the number of occupation is large, the investment is large, the production efficiency is low, and the particle size control of the product is difficult. Although the ordinary external circulation continuous crystallizer has obvious improvement in heat transfer efficiency and production capacity, there are no special components for enhancing mass transfer inside the crystallizer. Improves the crystallization process. Using the existing crystallization kettle, the crystallization is slow, t...
