The utility model relates to leaching device, concretely relates to scrape flat compaction's
solid -liquid separation
discharge leaching device. Including leaching ware, leaching ware is by the fixed cylinder wall of outside, the rotating shaft of inside center and is divided a plurality of leaching grid by separating plate and is formed, leaching ware bottom is equipped with the oil collecting hopper, the oil collecting hopper is by the grid plate and is separated into feed grid, a plurality of oil collecting grid, liquid supplementing grid, overflow grid, scraping flat grid,
discharge grid in turn along the rotating direction of rotating shaft, leaching grid bottom is equipped with fixed false bottom,
discharge grid connects
solid discharge conveying device,
solid discharge conveying device opens
branch line solid conveying device, and the discharge end of solid conveying device is located above the leaching grid corresponding to overflow grid, and the scraping flat mechanism is equipped above the leaching grid above scraping flat grid. The utility model discloses through setting up scraping flat mechanism and compacts the
solid material scraping flat, further reduces the gap between solids, makes
solvent overflow as far as possible, reduces the pressure of subsequent solid -liquid separation.
