Description
Technical field
The present invention relates to a kind of magnetic particle separator, in particular, provide the device of magnetic particle in a kind of magnetic separation fluid utilizing magnetic field to produce.
Background technology
Being separated by magnetic particle in the fluids such as air, liquid, breeze, is the basic technology demand of environmental protection, metal recovery, ore dressing field.Environmental protection needs be separated by the heavy metal in waste liquid and reclaimed; Magnetic metal in industrial refuse needs to recycle; Magnetic concentrator tool needs the efficiency improving ore dressing; Air containing magnetic dust needs purification and Footwall drift material.
The technology of magnetic separation magnetic particle is utilized to receive the concern of people in the application of ore dressing, metal recovery and purifying exhaust air, waste liquid in recent years, successively disclose many innovation and creation, as Chinese patent 200620162175,200820117746,200610146181,200810030485 etc.The ubiquitous difficult problem of these innovation and creation is inferior separating effect, and consumed energy is high.
Summary of the invention
The object of this invention is to provide a kind of mangneto fluid screening plant, large-sized magnetic pole and magnetic field can be divided into less space by the fluid bolter structure of this device, makes magnetic particle be effectively separated and be 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 space under magnetic pole covers and be independently separated cavity, the magnetic field space that the magnetic conduction wire rod of the fluid bolter be made up of multilayer screen cloth in each cavity and non-magnetic wire rod are placed is divided into the short space of several high-gradient magnetic fields and magnetic equipotential, in fluid bolter, the magnetic conduction wire rod of screen cloth is placed along the orthogonal direction of fluid bolter and magnetic pole relative motion, non-magnetic wire rod is placed along direction of relative movement, screen plane is vertical with the direction of magnetic field magnetic induction.Fluid to be separated enters along the magnetic conduction wire rod placement direction of fluid bolter, and the magnetic particle after separation is discharged along the magnetic pole direction of motion, and the non-magnetic fluid after separation is discharged along the opposite side in former direction.After being separated, the discharge direction of magnetic particle is with the direction that separated fluid passes through close to orthogonal, and both passages of flowing are relatively independent.
The fluid bolter be made up of multi-disc screen cloth, every sheet screen cloth, by magnetic conduction wire rod and non-magnetic wire rod cross weld or bonding forming, is namely combined as fluid bolter after the such screen cloth of multi-disc stacks by identical order.Form multiple small space after fluid bolter is placed between two magnetic poles, produce high magnetic field gradients space between the magnetic conduction wire rod on two adjacent screen clothes, attract the magnetic particle in fluid; With the parallel placement of a slice screen cloth magnetic conduction wire rod between space be in same magnetic field gradient under, as fluid inlet and outlet passage.Fluid to be separated is flow through in each short space parallel with magnetic conduction wire rod in fluid bolter, each short space between adjacent screen mesh magnetic conduction wire rod is entered at magneticaction magnetic particle, these two groups of spaces are formed relatively separately and close to orthogonal fluid access way and magnetic particle enrichment channel, when magnetic pole and fluid bolter are along the direction relative motion that non-magnetic wire rod is placed, magnetic particle is then discharged along Movement in Magnetic Field direction along non-magnetic wire rod placement direction under pulsation magneticaction.
The size of screen cloth mesh can be selected according to the size of separated fluid particle thing, and in unit are, the quantity of mesh is many, good separating effect, but should ensure that in fluid, particle can pass through smoothly.If screen cloth by magnetic conductive metal and non-magnetic metal solder shaping, the material that resistivity is high should be selected, otherwise larger eddy-current loss can be produced.When screen cloth adopts magnetic conductive metal wire rod and organic wire bonding forming, organic wire can select 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 differing half grid each other, the spatial distribution of fluid bolter internal magnetic field gradient can be improved, be conducive to the separation of magnetic particle and shift out.For the fluid of the flowing that can suspend, such as sludge mud, fluid passage can horizontal positioned.For the breeze of the flowing that can not suspend, fluid passage needs vertical placement, relies on gravity that breeze is flowed.For improving the circulation of fluid and controlling the speed of fluid motion, electromagnetic shaker can be installed, make fluid bolter do overall vibrations, be also conducive to movement and the collection of magnetic particle.For being separated of fluid liquid and breeze, fluid bolter should be fixed in a separating tank, mobile or rotary pole; Then can optional m igration or rotating fluid bolter with being separated of fluid liquid for gaseous state.Adopt the motion mode of rotating fluid bolter, the centrifugal force of gas and liquid flow can be provided simultaneously, in screen cloth, magnetic conduction wire rod and non-magnetic wire rod angle intersected with each other suitably can adjust according to the shape of hydromechanical principle and circumference, make magnetic conduction wire arrangement produce arc line shaped to bend, the angle that non-magnetic wire arrangement along the circumferential direction has a magnetropism particle output channel to tilt, is conducive to the collection of magnetic particle.
