The feed hood 3 is used to put the dust collected from the iron area, and the dust falls on the vibrating screening plate 8 for screening. The waste residue remains on the screening plate 8, and the dust falls into the dust collecting port 5 through the screening plate 8. Then the waste residue rolls through the screening plate 8 to the recovery port 6 to be collected and recycled. The dust suction pipe 4 is used for an external dust suction device, which can recover the dust raised in the screening box 1 during screening to prevent it from spreading to the outside.
[0024] The interior of the screening box 1 is plugged with a No. 1 frame 10, and the No. 1 frame 10 is located between the dust suction pipe 4 and the dust collecting port 5.
