Problems solved by technology

[0002] Traditional multi-stage screening equipment mainly includes multi-layer plane screens, circular vibrating screens, etc., and its structure is a plane composite body. Due to its small screening surface and vibration as the power source, the classification and screening noise is large, It is easy to pollute the environment with dust, low efficiency and high energy consumption. At the same time, it also has certain harm to the structure of the equipment. Generally, the screen of the vibrating screen is easily damaged, and the welds of the structure are easy to fatigue and burst.

Abstract

The present invention belongs to the field of material screening machinery, and is one kind of multi-layer coaxial rotary sieve for screening metallurgical slag. The multi-layer coaxial rotary sieve includes a multi-layer coaxial cylindrical screen rotating around one shaft inside the outer tank, with the screen layers having gradually increased diameters and gradually decreased mesh size; an outer tank with one material inlet in the top and several material outlets corresponding to different screen layers in the bottom; spiral pushing boards inside the screen layers with size matching the diameter of the cylindrical frame separately; and screen fixing rack to connect the screen layers and to connect the spiral pushing boards. The present invention may be used in screening metallurgical slag into several grades of different sizes.

Description

technical field [0001] The invention belongs to the field of material sorting and processing machinery, and relates to a rotary sieve for screening metallurgical slag. Background technique [0002] Traditional multi-stage screening equipment mainly includes multi-layer plane screens, circular vibrating screens, etc., and its structure is a plane composite body. Due to its small screening surface and vibration as the power source, the classification and screening noise is large, It is easy to pollute the environment with dust, low efficiency and high energy consumption. At the same time, it also has certain harm to the structure of the equipment. Generally, the screen of the vibrating screen is easily damaged, and the welds of the structure are easy to fatigue and burst. However, because the single-layer rotary screen adopts a continuous screening method from coarse to fine, most of the materials are always in the process of repeated screening, so there are always problems su...
