Apparatus and method for mixing solid and liquid

Abstract

The invention is applicable to the field of devices for mixing solids and liquids, and especially relates to an apparatus for mixing an ultrafine powder with a liquid to form a high-viscosity or high-concentration liquid. The apparatus comprises: at least one solid supply device; at least one liquid supply device; a liquid distribution chamber, wherein a supplied liquid is distributed in the liquid distribution chamber at a predetermined flow rate; a solid conveying chamber for conveying the solid from the solid supply device to a mixing chamber by a screw feeding device; the mixing chamber used for mixing the supplied solid with the liquid to form a suspension; and a rotor chamber, wherein the suspension is rotated in the rotor chamber and is output from an outlet of the rotor chamber inorder to generate a suction effect in an inlet area of the rotor chamber, and the suction effect makes air on the surface of the supplied solid surface substantially discharged. The invention providesthe mixing apparatus having the advantages of simple structure, low energy consumption, simplicity in control, and no blockage or leakage.

Description

technical field [0001] The invention relates to a field of equipment for mixing solids and liquids, in particular to equipment for mixing superfine powders and liquids to generate high-viscosity or high-concentration liquids. The invention also relates to a method for mixing solids and fluids. Background technique [0002] In the process of dispersing and mixing the powder into the liquid, with the development of powder technology and nanotechnology, the specific surface of the powder is large, and a large amount of gas is adsorbed on the surface, resulting in the infiltration of these ultrafine powder and liquid and the infiltration of the powder Difficult to disperse in liquid. [0003] In the patent ZL 02816085.1 "Apparatus and method for mixing solids and liquids" (hereinafter referred to as "Patent No. 851"), this patent uses a compression chamber that is equivalent to the action of a jet pump, and generates a suction effect through the rotor, combining the two A ball ...

AI Technical Summary

Problems solved by technology

When the rotor of the No. 607 patent sucks powder and liquid into the processing chamber, due to the uncontrollable liquid flow rate and powder delivery rate, it will cause the liquid to be discontinuous and cause cavitation (cavitation) effect or large pieces of powder to be crushed. The problem of inhalation, both of which can cause the liquid and powder to not fully infiltrate and mix, and may even cause agglomeration and blockage; of course, too much liquid suction and too little powder suction can also cause mixing The unevenness; at the same time, the discharge of the mixed liquid will also cause failure due to the above reasons

In addition, one component of the rotor realizes the work of suction, mixing and discharge, which consumes a lot of energy and requires a lot of mechanical strength, especially in the case of high viscosity and high concentration liquid, the problem is greatly magnified
