Abstract

The invention discloses a white carbon black stirring device which comprises a tank body with the hollow interior, wherein a stirring shaft is arranged in the tank body; a plurality of first vanes, which are centrosymmetric about the axis of the stirring shaft, are arranged at the upper section of the stirring shaft; a plurality of second vanes, which are centrosymmetric about the axis of the stirring shaft, are arranged at the lower section of the stirring shaft; the outer diameters of the first vanes are larger than those of the second vanes; a bracket is also arranged outside the tank body; a groove is formed in the bracket; the tank body is rotatably arranged in the groove; a turntable is arranged at the bottom of the groove and drives the tank body to rotate on the bracket; during stirring, the rotation direction of the bracket is opposite to that of the stirring shaft. The white carbon black stirring device is high in stirring efficiency and stable in stirring.

Description

technical field

[0001] The invention relates to the field of white carbon black production, in particular to a white carbon black stirring device. Background technique

[0002] White carbon black, also known as hydrated precipitated silica, is a white amorphous fine powder, and has a series of advantages such as high temperature resistance, non-combustibility, and good electrical insulation. It is mainly used as a reinforcing agent for rubber and is an important silicon It is an inorganic functional powder material. Most of them are prepared by traditional precipitation method in China. They use sodium silicate (sodium silicate) solution and sulfuric acid as raw materials, adjust the pH value at a certain temperature to obtain silica precipitation, and then press the slurry from the reactor. The filter is filtered and washed to remove sodium sulfate and impurities, and then the obtained filter cake is liquefied into a paste slurry by high-speed stirring, which is called bea...
