Abstract

The invention discloses a wind-magnetic dry separation device and a magnetic bead recovery method for improving the utilization rate of fly ash. The wind-magnetic dry separation device is used for screening magnetic beads from magnetic materials and comprises a transmission assembly, a magnetic assembly and an air draft assembly; the transmission assembly comprises a conveying part, and the conveying part conveys the magnetic materials to a magnetic separation area corresponding to the magnetic assembly; and when the air draft assembly generates negative pressure in the magnetic separation area, the magnetic assembly keeps the magnetic beads on the conveying part based on the magnetic force of the magnetic beads and the magnetic force of the magnetic assembly, and the air draft assembly sucks away excess materials, so that the conveying part conveys the magnetic beads to a designated area. According to the technical schemes, the technical problem that the grade of iron extracted from solid waste is low in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of resource recovery equipment, in particular to a wind-magnetic dry separation device and a magnetic bead recovery method for improving the utilization rate of fly ash. Background technique [0002] Coal-fired plants generate large amounts of solid waste (fly ash). Solid waste (such as fly ash) contains more iron ore. Screening magnetic beads from these solid wastes is beneficial to the effective recycling of iron resources. [0003] Taking fly ash as an example, my country's fly ash is mostly used in traditional projects such as burning bricks, building roads, and making cement and concrete admixtures. Only a few domestic power plants have installed fly ash dry separation and iron extraction facilities. The fly ash is treated with iron extraction and enrichment, but due to the simple process, only rough concentrate with an iron grade of about 45% can be produced, which cannot be directly used as a sinteri...
