Simple and efficient two-way stirring device for production of white carbon black

Abstract

The invention discloses a simple and efficient two-way stirring device for production of white carbon black. The bottom of a stirring shaft is laterally provided with a first stirring rod. The stirring shaft at the upper part of the first stirring rod is orderly and laterally provided with a second stirring rod and a third stirring rod. The first, second and third stirring rods are respectively and uniformly provided with a plurality of stirring plates. The upper part of the stirring shaft is respectively connected to first stirring blades and second stirring blades from top to bottom. The stirring shaft is provided with a plurality of rows of raised heads. Based on the existing stirring tank, the stirring shaft is improved and upper and lower materials are circulated and convected so thatthe mixing efficiency is improved and the cost is greatly reduced. The improved structure can realize forward and reverse stirring of the motor. A speed variable motor changes the stirring rate, prevents resonance at the same frequency and reduces the tank shaking.

Description

Background technique [0001] With the rapid development of my country's automobile industry, the demand for silica continues to grow. The role of silica in rubber products is as a reinforcing agent, and it also has anti-aging properties; the main methods of producing silica are gas phase method and precipitation. At present, most domestic manufacturers use the precipitation method to produce white carbon black. When producing white carbon black by the precipitation method, industrial water glass is used to react with acid, and the white carbon black is obtained through precipitation, filtration, washing, beating, and drying. During the beating process , using a stirring tank to stir the white carbon black filter cake, the stirring efficiency of the existing stirring tank is low, and there is a problem of uneven stirring and low quality. [0002] Although the publication number is: CN103752203B, a white carbon black stirring device is disclosed, which achieves the problem of makin...
