Rotary type automatic material discharging crystallizer

Abstract

The invention discloses a rotary type automatic material discharging crystallizer. The rotary type automatic material discharging crystallizer comprises a casing, a temperature adjusting tank, a bracket and a speed reducer motor, wherein the casing comprises a casing body, a connecting pipe, a cover plate and a transmission shaft; a lower end port of the connecting pipe is connected with a top hole of the casing body; the cover plate is arranged on an upper end port of the connecting pipe; the lower end of the transmission shaft is arranged at the center of the cover plate, the upper part of the transmission shaft is arranged at the upper part of the bracket through a bearing, and a driven belt wheel is arranged at the upper end of the transmission shaft; a driving belt wheel is arranged on the speed reducer motor, and is connected with the driven belt wheel through a belt; four-end spiral type stirring material guide blades are uniformly distributed on the circumference of the inner wall of the casing body in the axial direction, and the upper ends of the four-end spiral type stirring material guide blades are respectively connected with four through holes which are uniformly distributed in the lower part of the connecting pipe; a material discharging guide plate is arranged on the four through holes; a material collecting tank is arranged on the bracket, and corresponds to the material discharging guide plate; the axis of the casing body forms an angle with the horizontal line.

Description

technical field [0001] The invention relates to a crystallizer, in particular to a rotary automatic discharging crystallizer. Background technique [0002] There are many types of existing crystallization equipment, which can be divided into two categories: stirring type and relatively static type according to the flow characteristics of materials. The existing liquid flow crystallizer mainly includes a shell and a stirrer, the shell is usually fixed on a support, and the stirrer is arranged on the shell. For the flow crystallization method of the crystallization liquid, the crystallization is mainly realized by the flow of the material in the shell driven by the paddle of the stirrer. The main disadvantage of this method is that it is difficult to achieve uniformity in the upper and lower parts, the center and the surrounding edge of the shell, resulting in uneven saturation of the upper and lower parts, the central part and the surrounding edge, long crystallization perio...

AI Technical Summary

Problems solved by technology

The main disadvantage of this method is that it is difficult to achieve uniformity in the upper and lower parts, the center and the surrounding edge of the shell, resulting in uneven saturation of the upper and lower parts, the central part and the surrounding edge, long crystallization period and poor quality.

Especially in the middle and late stages of crystallization, when a part of the crystals have been crystallized, the crystals have high density and heavy weight, and are easy to settle in the lower part, thus causing serious uneven material flow, and at the same time resulting in uneven grain size and compactness. , affecting the quality

And because the crystallized grain sinks, it is easy to block the discharge port. When the crystallization is completed, the material is often not released, and the discharge is difficult, resulting in problems such as difficulty in discharging.
