Carbon black pelletizer

Abstract

The invention provides a carbon black pelletizer. The carbon black pelletizer comprises a coextrusion section pelletizer body and a rolling drying section pelletizer body which are connected with eachother, and a pore plate is arranged at the junction of the coextrusion section pelletizer body and the rolling drying section pelletizer body; the coextrusion section pelletizer body is provided witha carbon black inlet and a pelletizing water inlet, and the rolling drying section pelletizer body is provided with a carbon black outlet; the two pelletizer body sections are internally provided with high-speed shafts, the high-speed shaft located in the coextrusion section pelletizer body is provided with a low-speed shaft, and the low-speed shaft is provided with stirring teeth and a packing auger; the high-speed shaft located in the rolling drying section pelletizer body is provided with a rolling cylinder, and the end face, facing the pore plate, of the rolling cylinder is provided witha blade. By means of the carbon black pelletizer, the uniformity of carbon black particles can be improved, fine powder generated during carbon black pelletizing can be reduced, and the particle sizeof carbon black particles can be controlled.

Description

technical field [0001] The invention relates to chemical production equipment, in particular to a granulator used in carbon black production. Background technique [0002] At present, carbon black production enterprises mostly use wet granulators for granulation, but the wet granulators in the prior art only rely on the stirring of the stirring teeth and the adsorption of carbon black, so the carbon black particles produced are uneven and fine powder. If the content is large, the quality of carbon black products will decline, thereby restricting the influence of carbon black production abroad. Contents of the invention [0003] In order to improve the uniformity of carbon black particles and reduce the fine powder produced by carbon black granulation, the invention provides a carbon black granulator. [0004] A carbon black granulator provided by the invention comprises a connected mixing extrusion section body and a spheronizing drying section body, an orifice is arrange...
