Embodiment Construction

[0018] Combine figure 1 , The non-magnetic conductive wire 1 and the magnetic conductive wire 2 are stacked close to orthogonally, and are welded or bonded at the intersection 3 to form the screen of the fluid separation screen. The magnetic conductive wire and the non-magnetic conductive wire in the screen are in their respective planes. The magnetic wire is made of a magnetic metal material, and the non-magnetic wire can be a non-magnetic metal material or a non-metal material, such as fiber reinforced plastic. When selecting metal materials, materials with high resistivity should be selected, otherwise large eddy current losses will occur. in figure 2 , image 3 , Figure 4 , Figure 5 Among them, the magnetic path of the magnetic conductive material 8 provides the magnetic potential with the excitation coil 9, and the multiple screens stacked in the separation cavity 5 of the non-magnetic shell under the magnetic pole form the fluid separation screen 4, and the plane of ea...

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 by using magnetic force generated by a magnetic field. Background technique [0002] Separating the magnetic particles in air, liquid, mineral powder and other fluids is a basic technological 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 mineral processing machinery needs to improve the efficiency of mineral processing; air containing magnetic dust needs to be purified and recycled metal substances. [0003] In recent years, the application of magnetic particle separation technology in mineral processing, metal recovery and purification of waste gas and waste liquid has attracted people's attention. Many inventions have been discl...
