A uniform mixing device for preparing resin powder with high liquid content and its application

Abstract

The invention discloses a uniform mixing device for preparing high-liquid-content resin powder and the application of the uniform mixing device. The uniform mixing device comprises at least two mixing cylinders. Each mixing cylinder comprises an inner cylinder body, an outer cylinder body, a temperature detecting element, a liquid-powder co-feeding feeder, stirring blades, a motor I and a discharge port, wherein an interlayer is formed between the inner cylinder body and the outer cylinder body; a water inlet and a water outlet are formed in the outer cylinder body; the temperature detecting part of the temperature detecting element is located inside the inner cylinder body; the liquid-powder co-feeding feeder is arranged at the top of the mixing cylinder; the stirring blades are located at the bottom of the interior of the mixing cylinder; the motor I is connected with the stirring blades; the discharge port is formed in the bottom of the mixing cylinder. According the uniform mixing device, liquid can be in full contact with the powder and gradually permeate into the powder, so that uniform distribution is achieved. In this way, the uniform mixing device can be widely applied to the high polymer material modification field.

Description

technical field [0001] The invention relates to a mixing device, in particular to a uniform mixing device for preparing resin powder with high liquid content and its application. Background technique [0002] Many kinds of resin materials are often used in the modification of polymer materials, in the form of solid, powder, liquid and so on. Some materials can be directly fed into the extruder by adding them in proportion and converging at the discharge port, but some materials, such as powder and liquid, can be pre-mixed with suitable mixing equipment to achieve uniform material. Especially for resin powder materials with high liquid content, the liquid does not only adhere to the surface of the powder, but penetrates into the interior of the resin powder, and the liquid distribution must be uniform. Once the liquid is unevenly distributed, the powder with different liquid content will cause different feeding rates due to different densities, resulting in unstable product ...

AI Technical Summary

Problems solved by technology

The mixing device can solve the problems of uneven mixing of liquid and resin powder in the prior art, the powder absorbs less liquid, and is easy to agglomerate, etc.
