AI Technical Summary

Technical Problem

Existing reaction vessels used for optical pigment production suffer from uneven mixing. A single stirring rod is insufficient to cover all areas inside the vessel, resulting in long reaction times and poor uniformity.

Method used

The design employs a three-dimensional flow field, which incorporates uniformly distributed baffles and a stirring mechanism within the tank, including a rotating tube, rib grooves, support rods, ribs, and stirring rods. Combined with worm gear transmission and belt transmission, this achieves the circular motion of the rotating tube and the reciprocating motion of the support rods, forming a three-dimensional stirring path and eliminating mixing blind spots.

Benefits of technology

It significantly improves mixing efficiency and uniformity, accelerates the chemical reaction of pigments inside the vessel, and enhances the optical properties and hue stability of the pigments.

Abstract

This utility model discloses a reaction vessel for producing optical pigments, including a tank body. The tank body has uniformly distributed baffles inside, a support frame on its upper surface, and a stirring mechanism. The stirring mechanism includes a rotating tube, rib grooves, a support rod, ribs, and stirring rods. The rotating tube is rotatably connected to the top of the tank body via a bearing. The support rod is slidably connected inside the rotating tube. Uniformly distributed stirring rods are provided outside the support rod. Ribs are formed on the inner wall of the rotating tube, and ribs are provided on the outer side of the support rod. The ribs are slidably connected to the inner sides of adjacent rib grooves. A microcontroller is located outside the tank body, and its input is electrically connected to an external power source. This reaction vessel for producing optical pigments features three-dimensional flow field coverage, eliminating blind mixing zones inside the vessel body, significantly improving mixing efficiency and uniformity, and accelerating the chemical reaction of pigments inside the vessel body.
