The present invention provides a separator device which is used for separating the solid matter from the fluid containing the solid matter. The separator device comprises the following components: sieving devices (240, 242) which are installed in a container (206) and comprises a box body (204) and at least one sieve (240, 242) that is positioned in the box body (204) or on the box body; a vibrating device (230) used for vibrating the at least one sieve; a main conveying device (208) which is positioned under the at least one sieve (240, 242) for eliminating the solid matter comprising liquid in the container (206); an auxiliary treating device (220) which is used for further treating the solid matter comprising liquid; and a moving device (210) which is used for receiving the solid matter that comes from the main conveying device (206) and comprises liquid and moving the solid matter comprising liquid to the auxiliary treating device (220). The material to be treated can flow into at least one sieve (240, 242). The liquid in the material can flow into and through at least one sieve (240, 242). At least one part of the container (206) is installed below at least one sieve (240, 242).
