AI Technical Summary

Technical Problem

Traditional crystallizers suffer from low cooling efficiency, long crystallization cycles, insufficient heat exchange, and unreasonable stirring mechanism design, all of which affect crystallization uniformity.

Method used

The fast crystallizer adopts a double-layer structure, with spiral guide vanes and a cooling jacket between the inner and outer cylinders. Combined with propeller and anchor-type stirring blades, the shaft speed is controlled by a servo motor to achieve reverse flow and secondary circulation of the liquid. With segmented temperature control, a temperature gradient is established.

Benefits of technology

It improves cooling efficiency by 50%, shortens crystallization time to 1/3 of conventional equipment, concentrates crystal particle size distribution, and reduces energy consumption by 35%, making it suitable for crystallizing heat-sensitive materials.

Abstract

The utility model discloses a quick-setting crystallizer which comprises an outer cylinder body, a spiral flow deflector is arranged between the outer cylinder body and an inner cylinder body, a cooling interlayer is fixedly installed on the inner side of the inner cylinder body, the upper end of the outer side of a shaft rod is fixedly connected with a push type stirring blade, and the lower end of the outer side of the shaft rod is fixedly connected with an anchor type stirring blade. The bottom end of the shaft rod is fixedly connected with a flow guide cone, feed liquid enters from a top feed port, a cooling medium is reversely introduced into each interlayer from top to middle to bottom, cooling water spirally moves through spiral flow deflectors, and the heat exchange coefficient is increased by more than 40%; crystal mush is guided by the flow guide cone to form secondary circulation, full-volume mixing is realized by matching with the double-structure stirring blades, and a temperature gradient of 10-25 DEG C / m is established through segmented temperature control, so that ordered growth of crystals is promoted; according to the device, the rotating speed of the shaft rod is controlled through the servo motor, the flowing speed of materials is adjusted, and the materials can be uniformly mixed, so that the cooling efficiency can be improved, the crystallization efficiency is improved, and the energy consumption is reduced.
