DEFOAMING APPARATUS FOR HIGH-VISCOSITY PURE-CHITOSAN SPINNING SOLUTION

摘要

A degassing device for high-viscosity pure-chitosan spinning solutions having a reaction vessel and stirring device. A feed port and vacuum port are disposed at the upper part of the reaction vessel, an inner cylinder body is fixedly disposed in the center position of the reaction vessel which also has a discharge port, the upper cylinder opening of the inner cylinder body is closed and the lower cylinder opening is open, an umbrella-shaped dispersion plate is fixedly disposed at the periphery of the upper half part of the inner cylinder body, a gap is formed between the outer edge of the umbrella-shaped dispersion plate and the inner wall of the reaction vessel, and small liquid outlet holes are distributed on the part of the inner cylinder body above the umbrella-shaped dispersion plate. The stirring device has a stirring shaft with screw propeller and stirring power unit. The upper end of the stirring shaft is mounted to the stirring power unit, the stirring shaft passes through a mechanical sealing device and enters the reaction vessel with the lower end fixed on a seat-mounted bearing, the stirring shaft is superposed with the axial line of the inner cylinder body, and a gap is formed between the inner wall of the inner cylinder body and screw propeller.
