Embodiment Construction

[0018] combine figure 1 , the non-magnetic conductive wire 1 and the magnetic conductive wire 2 are nearly orthogonally stacked, and the screen mesh of the fluid separation screen is formed after welding or bonding at the intersection point 3 . The magnetically conductive wires and the non-magnetically conductive wires in the screen are in their respective planes. The magnetically conductive wires are made of magnetically conductive metal materials, and the nonmagnetically conductive wires can be made of nonmagnetic metal materials or non-metallic materials, such as fiber reinforced plastics. When selecting metal materials, materials with high resistivity should be selected, otherwise large eddy current losses will occur. exist figure 2 , image 3 , Figure 4 , Figure 5 Among them, the magnetic circuit of the magnetically conductive material 8 provides a magnetic potential by the exciting coil 9, and the multi-sheet screens stacked in the non-magnetically conductive she...

Abstract

The invention relates to a magnetic fluid sieving device, which mainly comprises a fluid separation sieve and a magnetic loop. The device is characterized in that magnetic wires and nonmagnetic wires in the fluid separation sieve formed by multiple layers of screen meshes in a plurality of independent fluid separation cavities under magnetic poles divide a magnetic field space into several minimal spaces of high gradient magnetic potentials and an equal magnetic potential; magnetic particles in a fluid are enriched in the high gradient magnetic field spaces under the action of magnetic force when the fluid flows through the fluid separation sieve; and when the magnetic poles relatively move along the direction of the nonmagnetic wires, the magnetic particles are acted by the magnetic force of the magnetic poles, move with the magnetic poles along a direction nearly orthogonal to a fluid flow channel, and are separated out. The magnetic fluid sieving device of the invention has the advantages of realization of continuous and efficient separation of the magnetic particles from the fluid, low operation energy consumption, and simple maintenance, and can be used for environmental protection, magnetic metal recovery, and magnetic mineral sorting.

Description

technical field [0001] The invention relates to a magnetic particle separation device, in particular to a device for separating magnetic particles in a fluid using magnetic force generated by a magnetic field. Background technique [0002] Separating magnetic particles from fluids such as air, liquid, ore powder is a basic process requirement in the fields of environmental protection, metal recovery, and mineral processing. Environmental protection needs to separate and recycle heavy metals in waste liquid; magnetic metals in industrial waste need to be recycled; magnetic beneficiation machinery needs to improve the efficiency of ore beneficiation; air containing magnetic dust needs to be purified and metal substances recovered. [0003] In recent years, the technology of using magnetic force to separate magnetic particles has attracted people's attention in the application of ore dressing, metal recovery, and purification of waste gas and waste liquid. Many inventions have ...
