Sedimentation filter box

The utility model discloses a sedimentation filter box provided with a box body, a box cover, a water inlet and a water outlet, wherein the box body is internally provided with a plurality of clapboards which divide the internal space of the box body into a plurality of sedimentation tanks; waste water flows through all the sedimentation tanks sequentially; since the waste water flows through a plurality of sedimentation tanks for sedimentation, the height of the clapboards are gradually elevated, and as the density of the gypsum is higher than that of the water, the gypsum is easy to settle and the gypsum in the waste water can be basically filtered after passing through the final sedimentation tank; the box body is internally provided with a wax blocking plate, since the density of the wax oil in the waste water is lower than that of the water, the wax blocking plate can retain the wax oil floating on the water surface; therefore, the sedimentation filter box can settle and filter both the gypsum slurry and the wax oil; the design of the floating ball component and the overflow hole ensures the sedimentation filter box not to have accidental leakage phenomenon; the first and second filter screen bags convenient for fast assembly and disassembly greatly reduce the cleaning work load of a user; and the bottom of the box body is installed with the roller, thus being convenient to move the sedimentation filter box.
