Conical solid-liquid separator

The utility model discloses a conical solid-liquid separator. The solid-liquid separator comprises a separator body, wherein a clear water collecting groove and an annular waste water collecting groove formed in the outer layer of the clear water collecting groove are formed inside the separator body, at least one layer of conical sieve is arranged above the clear water collecting groove, the upper part of the conical sieve located at the top layer is sleeved with an arc-shaped cone which is hollow inside, and the upper end of the arc-shaped cone is connected with a water inlet pipe. According to the solid-liquid separator, the at least one layer of conical sieve is arranged, waste water flows into the arc-shaped cone from the a water inlet pipe, and a water flow is dispersed by the arc-shaped cone and then enters the at least one layer of conical sieve to be filtered, so that a solid-liquid separation device and operation processes are simplified, the hydraulic loss is reduced, and the treatment efficiency is improved; and the solid-liquid separator is simple and compact in structure, and the energy consumption can be reduced substantially.
