A Permanent Magnet Induction High Gradient Disk Drive

Abstract

The invention discloses a permanent-magnet-induction-type high-gradient magnetic disk device. The device comprises a transmission device, induction-type magnetic disks, magnetic systems, a rack, a separation groove body, a magnetic material hopper and the like. The magnetic systems are located at the two sides of the separation groove body respectively, the induction-type magnetic disks are located between the magnetic systems, connected with the transmission device through a transmission disc and a supporting mechanism and suspended in the separation groove body, the magnetic material hopperis located on the upper portion of the separation groove body, the appearance of the magnetic material hopper is in a dustpan shape, and a bottom flow port and an overflow port are formed in the lowerportion of the separation groove body. Magnetic materials with cross sections in a pair of semicircles and a magnetic conduction baseplate are adopted for being spliced to provide a background magnetic field for the magnetic systems, honeycomb-shaped annular mediums are evenly embedded in the induction-type magnetic disks to generate a high-gradient induction magnetic field, the contact area of the induction-type magnetic disks and ore pulp is large, the magnetic field is evenly distributed, water spraying flushing is adopted for discharging finished ore, and the finished ore is gathered intothe magnetic material hopper through blocking strips on the surfaces of the magnetic disks. The device is reasonable in design, separation of heavy mediums and tailings is achieved, the recycling rate of the heavy mediums is increased, and the production cost of a coal preparation plant is lowered.

Description

technical field [0001] The invention belongs to the technical field of coal separation, and specifically relates to a permanent magnet induction high-gradient magnetic disk machine, in particular to an induction-type high-gradient dense-medium magnetic separator used for heavy-medium coal separation in the process of heavy-medium coal separation, and is especially suitable for rare Secondary recovery of medium or heavy medium in slime water. Background technique [0002] Dense medium separation is the core separation process of the current coal preparation plant production technology, and medium consumption is the main production cost of the current coal preparation plant. In addition, the magnetite powder lost in the tailings of the magnetic separator will affect the slime water treatment system to varying degrees. Improving the recovery rate of heavy medium and reducing loss is an effective way to reduce the cost of washing. [0003] The drum magnetic separator and the r...
