Three-section double-motor stirring device applied to white carbon black production

Abstract

The invention relates to a three-section double-motor stirring device applied to white carbon black production. A first stirring shaft and a second stirring shaft are each provided with three sections of stirring rods, the lengths of the three sections of the stirring rods arranged on the first stirring shaft are reduced in sequence from top to bottom, the lengths of the three sections of the stirring rods arranged on the second stirring shaft are increased in sequence from top to bottom, and multiple smooth arc-shaped protruding blocks are longitudinally arranged on the inner side wall of a tank. The three-section double-motor stirring device has the advantages that on the condition that double motors reach the same stirring speed, shaking of the tank can be greatly reduced; meanwhile, when one motor is used, increase of a load on the motor can be reduced, the service life of the motor is prolonged, by means of the second motor, when slurry is stirred, deposition of the partial slurry can be prevented, when stirring blades of the second stirring shaft rotate, the slurry can be made to overcome part of the gravity to be mixed with the slurry on the upper portion by means of centrifugal force, the speed is increased, and deposition is prevented.

Description

technical field [0001] The invention relates to a stirring device, in particular to a three-stage double-motor stirring device used in the production of white carbon black. Background technique [0002] With the rapid development of China'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 existing stirring tank has low stirring efficiency, and there is a problem of uneven sti...
