[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Referring to Figures 1-4 , an embodiment provided by the present invention: a centrifugal screening machine, including a support assembly. The support assembly includes a bottom plate 1, on which a support rod 2 is fixedly connected. The number of support rods 2 is four and they are arranged axially symmetrically. The upper end of the support rod 2 is fixedly connected to a top plate 3;

[0023] A collection housing 4 is arranged on the support assembly. The lower part of the collection housing 4 is funnel-shaped. The interior of the collection housing 4 has a screening chamber. The upper part of the screening chamber has a placement opening, and the bottom of the collection housing 4 has a discharge port. Two fixing seats 501 are fixedly connected to the upper surface of the collection housing 4 and are arranged axially symmetrically. An installation plate 502 is snap-connected to the fixing seats 501. A handle 504 is fixedly connected to the installation plate 502, and a screening motor 503 is fixedly installed below the installation plate 502;

[0024] A screening member 6 is arranged at the output end of the screening motor 503. The screening member 6 includes a screening upper cover 601 fixedly installed at the output end of the screening motor 503. An addition port for adding titanium dioxide is arranged on the screening upper cover 601. The screening upper cover 601 is adapted to the placement opening. A connecting edge 602 is fixedly connected to the lower part of the screening upper cover 601. A screening net 603 is threadedly connected to the connecting edge 602. A convex block 604 is fixedly connected to the outer surface of the screening net 603;
