Embodiment 1

[0048] see figure 1 , 4 As shown, as the basic structure of the present invention, the round table type high-efficiency dry magnetic separation device of the present invention includes a magnetic system 1 , a rotating magnetic medium 2 , a yoke 3 , a fluidization device 4 and a bracket 5 . The space between the rotating magnetic medium 2 and the fluidization device 4 is the sorting domain, the magnetic system 1 is a fixed magnetic system, and is located outside the rotating magnetic medium 2, that is, outside the sorting domain, and the yoke 3 is wrapped in the magnetic Outside of Department 1. The upper side of the sorting area is provided with a material inlet, and the lower side is provided with a fine material bin, a middle material bin and a tail material bin. The inside of the rotating magnetic medium 2 is provided with a protrusion of a magnetically permeable material that induces a high gradient magnetic field. The fluidization device 4 is externally connected with ...

Embodiment 2

[0052] see figure 2 and Figure 4 As shown, the enhanced air flow field is intervened alone, and the fluidization device 4 is connected to the air supply device. The fluidization device 4 is a conical air cavity or a conical annular air cavity, and the outer surface of the fluidization device 4 is a porous air distribution device. plate. The air supply device provides fluid to the air chamber of the fluidization device 4, and then disperses it into the sorting area through the porous air distribution plate, such as figure 2indicated by the arrow in . The angle of the side of the round table is greater than the accumulation angle of the material to avoid the accumulation of the material in the separation area under the condition of no air flow. Due to the absence of vibration, the interlayer thickness of the sorting domain can be further reduced. This design scheme has a simple and compact structure. The enhanced air flow not only loosens the materials on the surface of t...

Embodiment 3

[0054] see image 3 As shown, the enhanced air flow field is intervened alone, but the fluidization device 4 does not need an external air supply device, but is a truncated circular thin plate as in Embodiment 1. The airflow moves upwards through the lower side of the sorting zone. Under the action of the airflow, the material enters the sorting zone and is in a loose state. Among them, the fine-grained non-magnetic materials directly move upward with the airflow and leave the sorting zone. Coarse grains and some fine grains are non-magnetic. The material can continue to move downward and enter the tailing bin; after the competition of magnetic force, gravity and fluid drag, the fine-grained magnetic material moves upward and leaves the sorting area, and part of it is adsorbed on the rotating magnetic medium 2, and the coarse-grained and The fine-grained magnetic material can be smoothly absorbed by the rotating magnetic medium 2 . This design scheme first removes part of the...

Abstract

The invention relates to magnetic separation equipment, and discloses a circular truncated cone type efficient dry magnetic separation device which comprises a magnetic system, a rotary magnetic medium, a magnet yoke, a fluidization device and a support. The space between the rotating magnetic medium and the fluidization device is a sorting area, the magnetic system is a fixed magnetic system and located on the outer side of the rotating magnetic medium, and the magnetic yoke wraps the outer side of the magnetic system. A feeding port is formed in the upper side of the sorting area, and a concentrate bin, a middle bin and a tailing bin are arranged on the lower side of the sorting area. The inner side of the rotary magnetic medium is provided with a bulge which is made of a magnetic conductive material and induces a high-gradient magnetic field. The fluidization device is externally connected with special auxiliary equipment so as to fluidize the materials in the sorting area. By introducing a vibration force field or strengthening an air fluid force field, the materials are fluidized, and the material separation environment is improved, and by improving a magnetic system structure and a magnetic medium structure, the materials can be continuously adsorbed, desorbed and adsorbed on the basis of magnetic overturning in the separation process, so that the magnetic separation effect on fine materials is further improved.

Description

technical field [0001] The invention belongs to the technical field of magnetic separation equipment, and in particular, relates to a round table-type high-efficiency dry magnetic separation device. Background technique [0002] Magnetic separation is divided into dry type and wet type. From the analysis of flow field specificity, wet type and dry type magnetic separation occur in water and air media respectively. Water has a greater density than air, so the fluid resistance and lift force on particles in water are greater, and the agglomeration between particles is easier to be washed away by erosion; water has greater molecular polarity than air, so basically The influence of electrostatic force and van der Waals force between fine particles can be ignored; in addition, the influence of liquid bridge force between particles fully immersed in water does not need to be considered. Therefore, although dry magnetic separation has always been the preferred method for processin...
