Abstract

The invention discloses a production method for insoluble sulfur. The method comprises the steps of: sulfur melting and heating; quenching; conveying and solidification; coarse crushing; curing and fine crushing; and sieving, washing, drying, and oil charging. The invention also discloses a production apparatus of insoluble sulfur. The production apparatus consists of: a sulfur melting groove, a liquid sulfur pump, an electric heater, a reaction pot, a conveyer belt, a screw conveyer, aging pots, colloid mills, screen meshes, a rake dryer, a vacuum pump, a distillation tower, a condenser, a naphthenic oil storage tank, a submerged pump, a carbon disulfide storage tank, a metering pump and a sulfur purifier. Through the components, the process of sulfur melting, heating, quenching, conveying, solidification, coarse crushing, curing, fine crushing, sieving, washing, drying, and oil charging can be finished. The method and apparatus for production of insoluble sulfur provided by the invention can realize whole process closed production, completely eradicate dust, and achieve the purpose of environment-friendly and clean production.

Description

technical field [0001] The invention relates to an insoluble sulfur production method and equipment, in particular to a fully enclosed insoluble sulfur production method and production equipment. Background technique [0002] Insoluble sulfur is a polymer of sulfur, so named because it is insoluble in solvents such as carbon disulfide and tetrachloroethylene, and is widely used in the tire industry as a vulcanizing agent. With the radialization of tires, the demand for insoluble sulfur is increasing rapidly. Therefore, in recent years, more and more attention has been paid to the research on insoluble sulfur, and some production methods have also been developed, but there are some quality stability, safety, and environmental protection issues. [0003] For example, the invention patent with the patent number "ZL 200810073695.0" discloses a production method of insoluble sulfur, including melting sulfur, extraction, drying and crushing, and continuously producing insoluble s...
