High speed dynamic state on-line mixing device applicable to large-scale mixing

Abstract

The invention discloses a high speed dynamic state on-line mixing device applicable to large-scale mixing. The device is characterized in that a stirring component comprises a columnar body, wherein the lower end of the columnar body is provided with a reversed frustum body, a plurality of blades are arranged on the columnar body, each blade comprises a plurality of separate blade bodies, the blade bodies are tilted upwards wholly, the lower edges of the blades are upward arc-shaped surfaces, the upper edges of the blade bodies are upward inclined planes, the width of the blade bodies gradually narrows from roots to top portion, grooves for containing material liquid are formed between neighboring blades, and the surface of the reversed frustum body is provided with vertical backflow grooves which are staggered with the blade bodies on the periphery direction. The device has high mixing efficiency and strong mixing homogeneity, and can effectively prevent the residue of mixed materialliquid in tanks.

Description

technical field [0001] The invention relates to a dynamic on-line real-time mixing device for mixing two or more resin materials, especially a device suitable for a large difference in resin viscosity (greater than 10:1) or a large difference in resin ratio (greater than 10 : 1) mixing device. Background technique [0002] Mixing devices are usually used where two or more flowable materials or components need to be mixed together completely and uniformly. [0003] In the potting and sealing machine industry, epoxy resin, polyurethane and silicone resin are used as potting materials for electronic appliances, and various additives, such as fillers, pigments, diluents, accelerators, toughening agents and curing agents, etc., need to be added to improve its performance. Tests have shown that different proportions and different mixing uniformity have a great influence on the electrical and mechanical properties of potted products. Among them, the static mixer is familiar to e...

AI Technical Summary

Problems solved by technology

Due to factors such as unreasonable rotor structure and poor sealing, the mixing efficiency is low, and the material liquid cannot be completely and uniformly mixed, and the material liquid cannot be discharged smoothly according to the first-in-first-out order, which may easily cause the solidification of the material liquid and damage the equipment.

Once the material liquid breaks through the sealing part and enters the rotor assembly, it will accelerate its wear and cause the material liquid to leak; it is also easy to cause the material liquid to stick to the rotating shaft, causing the rotating shaft to fail to rotate, and the whole machine cannot work normally
