Abstract

The invention discloses a pulping tank for preparing white carbon black. Stirring blades of the pulping tank comprise at least one first blade and at least one second blade, the at least one first blade is perpendicular to a stirring shaft, the at least one second blade is inclined relative to the stirring shaft, and the inclination angle is larger than or equal to 40 degrees and smaller than or equal to 48 degrees; the first and second blades are arranged alternately along the stirring shaft, projections are evenly distributed at intervals of 90 degrees in the axis direction of the stirring shaft, upper and lower layers of pulp form turbulent flows by the aid of the stirring blades adopting the structures during stirring, so that the pulping uniformity is increased, and the pulping effect is improved.

Description

technical field [0001] The invention relates to the technical field of nanometer white carbon black production equipment, in particular to a beating tank for preparing white carbon black. Background technique [0002] White carbon black is the general term for white powder X-ray amorphous silicic acid and silicate products, mainly refers to precipitated silica, fumed silica and ultrafine silica gel, and also includes powdered synthetic silicic acid aluminum and calcium silicate etc. Silica is a porous substance whose composition can be SiO 2 nH2O means that nH2O exists in the form of surface hydroxyl groups. Soluble in caustic alkali and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid). High temperature resistance, non-combustible, tasteless, odorless, with good electrical insulation. [0003] In the production process of silica, the pulping (ie beating) of silica filter cake is an important link. First of all, the silica filter cake ...
