Solid liquid mixing device for preparing superfine slurry

Abstract

The invention discloses a solid liquid mixing device for preparing superfine slurry. The solid liquid mixing device comprises a liquid mixing feeding device, a solid pulverizing feeding device, a primary solid liquid mixing device, a conveying pump, a secondary solid liquid mixing device, a material return pipe and the like, wherein a pulverizing device performs primary pulverizing on solid particles, so that the mixing speed is accelerated; through the arrangement of a baffle plate and a blast blower, the solid particles are prevented from flying into air; a stirring paddle is arranged into aspiral paddle shape, so that mixed materials can be easily driven to rotate in an advancing way; a screen mesh type framework is arranged at the periphery of a tube body, so that the solid particlescan conveniently go in or out; the mixing speed is accelerated; an included angle of a stirring blade and a stirring shaft forms a certain angle, so that the pulverizing and mixing effects are reinforced. The solid liquid mixing device disclosed by the invention has the advantages that the air dust pollution cannot be caused; the mixing efficiency is high; the mixing speed is high; the continuousoperation can be realized; the goal of preparing the superfine slurry through solid liquid mixing can be fast and efficiently achieved.

Description

technical field [0001] The invention relates to a solid-liquid mixing device, in particular to a solid-liquid mixing device for preparing ultrafine slurry, and belongs to the technical field of material mixing equipment. Background technique [0002] In the manufacturing process of functional slurry products such as water-based color paste and coal-water slurry, it is an important process to disperse powdery or granular solids in liquids. At present, the common method of solid-liquid mixing is to add solid particles and liquid materials into the container according to a certain ratio, and mix them by mechanical stirring. However, when solid particles with smaller particle sizes are added to the liquid, the solid particles are easy to agglomerate, and the liquid can only wet the surface of the solid particle agglomerates, and cannot penetrate into the interior of the solid particles, so the solid particles cannot be fully absorbed. , Evenly dispersed in the liquid, prone to ...
