Partition board auxiliary material screening device

The invention is suitable for the field of screening devices, and provides a partition board auxiliary material screening device. The partition board auxiliary material screening device comprises a supporting driving mechanism, and further comprises a screening cylinder, first material filtering screen plates, second material filtering screen plates and large-particle auxiliary material discharging pipes. The screening cylinder is installed on the supporting driving mechanism, and the supporting driving mechanism is used for supporting the screening cylinder and driving the screening cylinder to rotate. The multiple first material filtering screen plates are fixedly installed on the inner wall of the screening cylinder in a circumferentially distributed mode. The second material filtering screen plates are further fixedly installed at the positions, between every two adjacent first material filtering screen plates, of the side wall of the screening cylinder. The multiple large-particle auxiliary material disc
