A drum screening machine for screening out nickel residual anodes is mainly composed of a tank (1), a drum (2), a gear reducer (3), a towing wheel (4), a chain (5), a feeding hopper (6), an oversize material discharge hopper (7), an undersize material discharge hopper (8) and a base (9). The drum screening machine for screening out the nickel residual anodes is characterized in that all the components are linked in a mechanical, screwed and welding manner, the drum driving manner of the drum screening machine is sprocket driving, and a driving device is composed of the gear reducer (3), the chain (5) and a chain fixing pin (11). Anode mud is screened out of screen holes in the drum and discharged out of the undersize material discharge hopper (8), and the nickel residual anodes are discharged out of the oversize material discharge hopper (7) at the terminal end of the drum as undersize materials. In the rotating process of the drum, six sets of lifting boards lift the nickel residual anodes alternately, so that the material stacking probability is fully decreased, and the phenomenon of discharge blocking caused by interwinding of copper wires on the nickel residual anodes is avoided; and due to the fact that the two corners of each lifting board are made to be round, the situation that copper wires are wound around and stacked on the lifting boards when hung on the lifting boards is avoided.
