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.
