Vacuum filtering machine for indissoluble sulfur solid and liquid separation

Abstract

The invention provides a vacuum filtering machine for indissoluble sulfur solid and liquid separation. The vacuum filtering machine can improve the suction filtration effect and the solid and liquid separation efficiency, can reduce the integrated large-scale investment cost and the generation cost of the insoluble sulfur, and can guarantee the suction filtration and separation effects of the soluble sulfur. The vacuum filtering machine comprises a shell, a discharging scraping plate, a driving mechanism and a suction filtration mechanism; a slurry inlet, a washing liquid inlet, a balance gasinlet, a solid outlet and a mother liquid suction filtration port are formed in the shell; the suction filtration mechanism comprises a suction filtration pipe, a filtering disk and a cover shell; thefiltering disk hermetically covers the opening at the upper end of the cover shell to form a separation chamber; the separation chamber is integrally sealed in the shell; and one end of the suction filtration pipe stretches into the separation chamber and the other end of the suction filtration pipe is connected with the mother liquid suction filtration port. The vacuum filtering machine is characterized in that the filtering disk can be driven by the driving mechanism to rotate; a slurry distributing tank, a washing liquid distributing tank and the discharging scraping plate are arranged above the filtering disk; and the slurry distributing tank and the washing liquid distributing tank are communicated with the corresponding slurry inlet and the washing liquid inlet.

Description

technical field [0001] The invention relates to process equipment for the preparation of insoluble sulfur, in particular to a vacuum filter for solid-liquid separation of insoluble sulfur. Background technique [0002] Vacuum filter for solid-liquid separation of insoluble sulfur Separation of insoluble sulfur solids from carbon disulfide liquid and soluble sulfur dissolved in carbon disulfide liquid, which is separated by vacuum filtration, the separation effect is good, and can obtain The powdery insoluble sulfur avoids the crushing operation of the insoluble sulfur filter cake in the later stage and can simplify the process. [0003] The existing vacuum filter 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 cut off, and then suction filtration is performed. The filter cake formed by in...
