The invention discloses a cyclone sedimentation filter separator. According to the cyclone sedimentation filter separator, suspended solids rotate in the cyclone sedimentation filter separator to generate an eccentric force, solid-phase particles with relatively large liquid-solid density contrast perform relative movement for primary separation sedimentation, and separated liquid with particles having relatively small density is filtered and separated to realize liquid-solid separation. The cyclone sedimentation filter separator shell comprises a conical tube (2), a cylinder (3) and a top end socket (12), wherein a center tube (5) and an inner conical tube (6) are arranged in the cylinder (3); the inner conical tube (6) is fixed on the inner wall of the cylinder (3); the center tube (5) is connected with the inner conical tube (6); a filter tube component (7) and a fixed plate (8) are arranged at the upper part of the inner conical tube (6); the filter tube component (7) is arranged on the fixed plate (8) through a bolt (10) and a nut (11); a vomit pipe (1) is arranged at the bottom of the conical tube (2); a liquid inlet pipe (4) is arranged in the middle of the cylinder (3); and a clear liquid outlet pipe (9) is arranged at the upper part of the cylinder (3). The cyclone sedimentation filter separator has a relatively wide particle range for separating suspended solids, so that the defect of low efficiency of traditional filter separation and sedimentation separation can be overcome, and the production efficiency can be greatly improved.
