step four: the sealing cover (2) at the top end of the filtering box body (1) is opened, the material taking hand wheel (18) is rotated by hands, so that the threaded connecting parts (19) at the top ends of the primary filter hopper (4), the secondary filter hopper (5) and the tertiary filter hopper (6) are separated from the threaded lantern ring (20), the primary filter hopper (4), the secondary filter hopper (5) and the tertiary filter hopper (6) are taken out, and the raw material filtering and recovering work is completed.
