AI Technical Summary

Technical Problem

Existing powder-liquid mixing devices are characterized by large footprint, inconvenience in relocation, and high cost, making it difficult to meet the needs of miniaturization and rapid mixing of large quantities of liquids.

Method used

A powder-liquid mixing chamber was designed. Through an annular compartment and a multi-inlet structure, the overflow and vortex effects are used to achieve rapid dispersion and uniform mixing of powder materials. Combined with a screw conveyor and metering sensors, the mixing accuracy and flexibility are ensured.

Benefits of technology

It achieves rapid dispersion and uniform mixing of powders, reduces equipment size, adapts to different proportion requirements, improves mixing efficiency and accuracy, and meets the requirements of making and using on the spot.

Abstract

The powder-liquid mixing bin comprises a tank body provided with an annular partition bin and a first liquid inlet, the annular partition bin comprises an outer peripheral wall and a conical inner peripheral wall which are sleeved with each other, the first liquid inlet is formed in the outer peripheral wall, and a discharging opening is formed in the middle of the upper side of the conical inner peripheral wall and is higher than the upper end face of the conical inner peripheral wall; an outlet is formed in the lower end of the conical inner peripheral wall and connected with a top inlet of a tee joint, an axial inlet of the tee joint serves as a second liquid inlet, and an axial outlet of the tee joint is used for being connected with a mixing pump; liquid entering from the first liquid inlet fills the annular gap between the outer peripheral wall and the conical inner peripheral wall and overflows into the conical inner peripheral wall through the upper end face of the conical inner peripheral wall, so that a circular-truncated-cone-shaped concave part is formed, and powder falls into the circular-truncated-cone-shaped concave part to form a primary mixture; liquid enters the second liquid inlet to take away the primary mixture and convey the primary mixture outwards; the powder-liquid mixing bin achieves the purpose of mixing and is beneficial to mixing and miniaturization at the same time.
