Continuous separating and drying system for wet-process production of insoluble sulfur

Abstract

The invention provides a continuous separating and drying system for wet-process production of insoluble sulfur. The technical problem that existing vacuum drying devices are limited in treatment capacity, thereby being incapable of being matched with working efficiency of vacuum filtering devices can be solved effectively. The system comprises a vacuum filtering device, a conveying device and a vacuum drying device. The system is characterized in that the vacuum filtering device comprises a filter shell, a discharging scraper, a turntable driving mechanism and a suction filtering mechanism, the suction filtering mechanism comprises a suction filtering pipe, a filtering disc and a housing, the filtering disc hermetically covers an upper-end opening of the housing to form a separation chamber which is arranged in the filter shell, the filtering disc is driven by the turntable driving mechanism, and a slurry distribution tank, a washing liquid distribution tank and the discharging scraper are arranged above the filtering disc; the conveying device comprises a conveyor shell, a shaftless screw conveyor and a screw conveyor driving mechanism, the conveyor shell is provided with more than two feeding and discharging ports, each discharging port is sequentially connected with a valve and the vacuum drying device, and the screw conveyor is shaftless.

Description

technical field [0001] The invention relates to the technical field of insoluble sulfur production equipment, in particular to a continuous separation and drying system for wet production of insoluble sulfur. Background technique [0002] The existing vacuum filtration device for solid-liquid separation of insoluble sulfur adopts intermittent operation. First, the slurry containing insoluble sulfur, soluble sulfur and carbon disulfide is quantitatively injected into the body, then the supply of the slurry is disconnected, and then suction filtration is performed. The filter cake formed by insoluble sulfur is scraped off and collected. In order to consider the overall process efficiency, the amount of slurry injected each time is relatively large, and the filter cake of insoluble sulfur produced is thicker. A thicker filter cake not only affects the efficiency of suction filtration and solid-liquid separation, but also affects the overall scale of insoluble sulfur Investment...
