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
The present invention relates to a kind of magnetic particle separator, a kind of device that utilizes magnetic particle in the magnetic separation fluid that magnetic field produces particularly is provided.
Background technology
Magnetic particle in the fluids such as air, liquid, breeze is separated, and is the basic technology demand of environmental protection, metal recovery, ore dressing field.Environmental protection need separate the heavy metal in the waste liquid also reclaims; Magnetic metal in the industrial refuse needs to recycle; The magnetic benficiation machinery need improve the efficient of ore dressing; The air that contains the dust that is magnetic need purify and reclaim metallics.
Utilize the technology of magnetic separation magnetic particle to receive people's attention in recent years in the application of ore dressing, metal recovery and purifying exhaust air, waste liquid; Successively many innovation and creation are disclosed, like Chinese patent 200620162175,200820117746; 200610146181,200810030485 etc.The ubiquitous difficult problem of these innovation and creation is an inferior separating effect, and consumed energy is high.
Summary of the invention
The purpose of this invention is to provide a kind of mangneto fluid screening plant, the fluid bolter structure of this device can be divided into less space with large-sized magnetic pole and magnetic field, magnetic particle is effectively separated and is collected.
Mangneto fluid screening plant of the present invention; Comprise at least one pair of magnetic pole and closed magnetic circuit; Be partitioned into several in the space under magnetic pole covers and independently separate cavity; The magnetic conduction wire rod of the fluid bolter that constitutes by the multilayer screen cloth in each cavity and the short space that non-magnetic conduction wire rod is divided into the magnetic field space of its placement several high-gradient magnetic fields and magnetic equipotential; The orthogonal direction of the magnetic conduction wire rod longshore current body bolter of screen cloth and magnetic pole relative motion is placed in the fluid bolter, and non-magnetic conduction wire rod is placed along direction of relative movement, and screen plane is vertical with the direction of magnetic field magnetic induction intensity.The magnetic conduction wire rod placement direction of treating separation of the fluid longshore current body bolter gets into, and the magnetic particle after the separation is discharged along the magnetic pole direction of motion, and the non magnetic fluid after the separation is discharged along the opposite side of former direction.The discharge direction of separation back magnetic particle and the direction that separated fluid passes through are near quadrature, and the passage that both flow is relatively independent.
By the fluid bolter that the multi-disc screen cloth is formed, every screen cloth promptly is combined as the fluid bolter by magnetic conduction wire rod and welding of non-magnetic conduction wire rod intersection or bonding forming after the such screen cloth of multi-disc stacks by identical order.The fluid bolter is placed between two magnetic poles the back and forms a plurality of small spaces, produces the high magnetic field gradients space between the magnetic conduction wire rod on two adjacent screen clothes, attracts the magnetic particle in the fluid; Be under the same magnetic field gradient with the space between the magnetic conduction wire rod of the parallel placement of a slice screen cloth, get into and passing away as fluid.Flow through in each short space parallel in the fluid bolter and treat separation of the fluid with the magnetic conduction wire rod; Get into each short space between the adjacent screen mesh magnetic conduction wire rod at magneticaction magnetic particle; These two groups of spaces form relatively separately and near the fluid access way and the magnetic particle enrichment passage of quadrature; When direction relative motion that magnetic pole and fluid bolter are placed along non-magnetic conduction wire rod, magnetic particle then in pulsation magneticaction lower edge the Movement in Magnetic Field direction discharge along non-magnetic conduction wire rod placement direction.
The size of screen cloth mesh can be selected according to the size of separated fluid particle thing, and the quantity of mesh is many on the unit are, good separating effect, but should guarantee that particle can pass through smoothly in the fluid.If screen cloth should be selected the high material of resistivity, otherwise can be produced bigger eddy-current loss by magnetic conductive metal and non-magnetic conductive metal welding fabrication.When screen cloth adopted magnetic conductive metal wire rod and organic wire bonding forming, organic wire can be selected hardness and the higher fibre reinforced plastics of intensity.If the magnetic conduction wire rod of adjacent two layers screen cloth is staggeredly placed by the distance of phase difference of half grid each other, can improve the spatial distribution of fluid bolter internal magnetic field gradient, help the separation of magnetic particle and shift out.For the flowing fluid that can suspend, sludge mud for example, the fluid passage can horizontal positioned.For the mobile breeze that can not suspend, the fluid passage needs vertical the placement, relies on gravity that breeze is flowed.Be the circulation of improving fluid and the speed of controlling fluid motion, electromagnetic shaker can be installed, make the fluid bolter do whole vibrations, also help moving and collection of magnetic particle.For separating of fluid liquid and breeze, the fluid bolter should be fixed in the separating tank, moves or rotary pole; Move or the rotating fluid bolter for then selecting separating of gaseous state and fluid liquid.Adopt the motion mode of rotating fluid bolter; The centrifugal force of gas and liquid flow can be provided simultaneously; Magnetic conduction wire rod and non-magnetic conduction wire rod angle intersected with each other can suitably be adjusted according to the shape of hydromechanical principle and circumference in the screen cloth; The magnetic conduction wire rod is arranged produced the bending of camber line shape, non-magnetic conduction wire rod is arranged the angle that along the circumferential direction has a magnetropism particle output channel to tilt, and helps the collection of magnetic particle.
