AI Technical Summary

Technical Problem

Existing ceramic slurry mixing devices tend to form dry clumps when ceramic powder is added rapidly, making it difficult for the powder to be wetted by the solvent. This severe agglomeration affects the fineness and uniformity of the slurry.

Method used

The design employs a combination of a vessel module, a feeding module, and a dispersing module. Quantitative feeding is achieved through alternating movement of valve plates. Combined with the extrusion of the pressure screw and the conical pressure cylinder, the low-speed release of the bottom dispersing hole, and the scraping of the reflux component and the spraying of the jet nozzle, the agglomerated powder is broken up, increasing the contact area with the solvent.

Benefits of technology

It effectively prevents powder from clumping in the solvent, refines the particle size distribution, improves the uniformity and dissolution efficiency of the slurry, and improves the subsequent molding effect.

Abstract

This invention discloses a slurry mixing device for ceramic production, belonging to the field of ceramic production technology. It includes a reactor module, a feeding module, and a dispersing module. The feeding module is movably mounted on the reactor module and connected to the dispersing module, driving the dispersing module to rotate continuously within the reactor. The feeding module contains two sets of alternating valve plates for quantitatively feeding ceramic powder into the mixing reactor. The bottom of the dispersing module's slurry shell is provided with several bottom-mounted dispersing holes for slowly releasing ceramic powder into the mixing reactor. This invention uses the feeding module to quantitatively feed the ceramic powder to be mixed in batches into the dispersing module for dispersion, reducing powder agglomeration in the solvent, refining powder particles, improving particle size distribution, and making the mixed product more uniform.
