On the basis of existing technology, the invention provides a kind of novel magnetic plant, it possesses magnetic-particle simultaneously and separates, washs, sieves three kinds of functions.
Electromagnetic sieve of the present invention comprises that the magnetic connection utmost point that closely is arranged in horizontal same polarity magnetic patch by opposed polarity interleaves the magnetic system that forms by certain interval.Raw material feed hopper, the system that connects material, frame and other parts are shown in figure ().It is characterized in that other parts are: (1) is positioned at the magnetic side of fastening, and the iron hydraulic pressure that links together with the magnetic connection utmost point permeates case; (2) be attached at the magnetic pole strength of the magnetic conduction pure iron clamping plate of each magnetic connection utmost point lower end as the magnetic connection utmost point; (3) do tangential motion along magnetic pole strength, closely contact with magnetic pole strength, having magnetic is the rotary screen of width; (4) can extremely descend moving linearly in the splaying at the magnetic connection, in order to collect the drawing mechanism of thin matter magnetic-particle.
Electromagnetic sieve of the present invention adopts to be upside down under the steel plate of hydraulic pressure infiltration case bottom surface and constitutes magnetic system to repeat to interleave each other the N and the S magnetic connection utmost point that are arranged in parallel.And leave the gap, parallel space of same distance between them.Each magnetic connection utmost point lower end all fixedly lastblock magnetic conduction pure iron clamping plate as the magnetic pole strength of the magnetic connection utmost point.This arrangement mode is considered from structural behaviour, permeate case bottom surface steel plate by hydraulic pressure between every pair of two adjacent magnetic connection utmost points, and the widely different road of magnetic of two pure iron magnetic pole strength formations semi-closed, this structure concentrates on very little magnetic separation space to magnetic energy product (being equivalent to the energy of position in the circuit) easily, is convenient to the magnetic energy acting.The following part of rotary screen is close on the magnetic pole strength.When moving at a slow speed in rotary screen is done, the water in the magnetic side of the fastening hydraulic pressure infiltration case just strip hole by the water tank bottom surface dashes and is mapped on the rotary screen compass screen surface material to be separated (if with kerosene replacement water better effects if).Because rotary screen and material to be separated are to be close on the magnetic pole strength or extremely hithermost local tangential the moving of doing of N utmost point S.At this moment, the magnetic force that makes progress that paramagnetic particle to be separated is suffered is adjusted to the power of penetrating of dashing of infiltration hydraulic pressure less than the suffered magnetic force of paramagnetic particle to be separated (accomplishing easily) greater than self downward gravity again.Like this, paramagnetic particle to be separated is under the effect of three kinds of power (magnetic force, from gravity and infiltration water impulse force).And non-magnetic particle only is subjected to the effect of downward self gravitation and infiltration water impulse force.Just non-magnetic particle and the very fast flushing of non magnetic dust that simply sticks on the paramagnetic particle get off.This cans be compared to catches paramagnetic particle with staff, will rinse out attached to the dirt on the paramagnetic particle.In addition, rotary screen is done on magnetic pole strength in tangential the moving.Paramagnetic particle can affect jump (spur paramagnetic particle with rotary screen in magnetic field, be easy to generate magnetic energy accumulation and releasing magnetic energy, make paramagnetic particle jump occur affecting on rotary screen) between different N and S magnetic pole strength.With rotary screen the chance of individual relative motion is arranged.When the diameter of paramagnetic particle less than the rotary screen compass screen surface on the aperture time, under the effect of magnetic force upwards, just, reach the purpose of sieving by the rotary screen compass screen surface.
The present invention compared with prior art can not only make paramagnetic particle to be separated obtain magnetic simply and separate, and by hydraulic pressure infiltration flushing with sieve.Make paramagnetic particle in separation, can choose the high fine-grained material of high-purity by specification requirement.
