AI Technical Summary

Technical Problem

Traditional conical ribbon screw mixers suffer from uneven mixing when processing highly viscous materials, making it difficult to effectively reduce the viscosity of the materials. This results in low mixing efficiency and can easily lead to energy waste and equipment damage. Furthermore, existing technologies struggle to accurately identify high-viscosity areas and effectively heat and mix them, affecting the quality control of the mixing process.

Method used

The design employs a combination of primary and secondary stirring units. The reciprocating motion of magnets and the magnetic field changes of electromagnets drive the rotation of the moving plate and rotating box, achieving multiple stirring of materials and scraping of the inner wall. Combined with the detection of high viscosity areas by piezoresistive resistors and adjustment of stirring parameters, the mixing uniformity and efficiency are improved.

Benefits of technology

It achieves uniform mixing of highly viscous materials, improves mixing efficiency, reduces material waste, enhances the ability to handle high-viscosity areas, and ensures the stability of mixing quality and the safety of the equipment.

Abstract

A conical ribbon-screw mixer, comprising a stirring barrel (1), a first-stage stirring unit (2), and a second-stage stirring unit (3), wherein the stirring barrel (1) is used for mounting and fixing the first-stage stirring unit (2) and the second-stage stirring unit (3); the first-stage stirring unit (2) is used for uniformly stirring materials in the stirring barrel (1); the second-stage stirring unit (3) is used for scrapping off high-viscosity materials attached to the inner wall of the stirring barrel (1) while uniformly stirring the materials in the stirring barrel (1); when the materials enter the stirring barrel (1), the materials are preliminarily stirred and mixed by means of the first-stage stirring unit (2), and when the second-stage stirring unit (3) encounters a locally high-viscosity material mixing region during stirring, the second-stage stirring unit performs secondary stirring and mixing on the materials.
