[0038] Combined with Figures 2-4As shown, the top of the uppermost screening device 1 is provided with a feeding port 12, which is connected with the interior of the uppermost screening device 1. The initial material can be introduced into the screening device 1 by injecting the initial material into the feeding port 12. The feeding port 12 can be in the shape of a funnel, and the large opening of the funnel is located at the side of the feeding port 12 away from the screening device 1.
