Abstract
The invention relates to a method for completely removing substances adsorbed by a permanent magnet. The method is characterized by including the following steps: a, enabling an electromagnet to be close to the permanent magnet adsorbing magnetic substances after the permanent magnet adsorbs the magnetic substances, wherein the magnetic field intensity of the electromagnet is larger than that of the permanent magnet, and the polarities of the ends at which the electromagnet is close to the permanent magnet are opposite; b, separating the permanent magnet from the electromagnet for a certain distance; and c, powering off the electromagnet to enable the magnetic substances adsorbed by the electromagnet to fall off. The method has the advantages that advantages of the electromagnet and the permanent magnet are fully played, so that small magnetic substances in powder materials can be removed easily, and the removing effect is improved substantially.
Description
Technical field
The present invention relates to the screening technique of industrial circle material, particularly the screening technique of powdery, granular material.
Background technology
In many industrial occasions, all must remove the magnetisable material in material, as the quartz sand process, be all the basic skills that adopts permanent magnet absorption magnetisable material, remove magnetisable material contained in quartz sand.The magnet used has two kinds, and a kind of is permanent magnet, and magnet is through special making, and magnetic can keep for a long time, and the magnetic field of low-intensity (3000～4000GS) in usually can producing no longer needs other energy during the absorption magnetisable material; Another kind is electromagnet, with solenoid, is wrapped on the iron body, and energising produces magnetic, and outage magnetic disappear, and can produce the magnetic field of high strength (more than 10000GS), and low-intensity magnetic fields in also can producing needs electric flux during the absorption magnetisable material
.permanent magnetism and electromagnetism respectively have characteristics, fully the phase trans-substitution.
The magnetisable material of wanting the removal magnet to adsorb, be easy to electromagnet, and outage disappears magnetic, and magnetisable material drops naturally; But very difficult to permanent magnet, more difficult when especially magnetisable material is fine particle, take various mechanical means by meeting, as with permanent magnet, indirectly adsorbed magnetisable material, this can reduce de-ferrous effect greatly, the magnetisable material particle that removal is tiny fully.
Summary of the invention
Purpose of the present invention is exactly that the permanent magnet adsorbent provided unloads eliminating method fully in order to solve the problem of the magnetisable material removal difficulty that permanent magnet adsorbs.
The technical solution used in the present invention is as follows:
A kind of permanent magnet adsorbent unloads eliminating method fully, it is characterized in that comprising the following steps:
A, after permanent magnet absorption magnetisable material, the magnetisable material by electromagnet near permanent magnet absorption, the magnetic field intensity of electromagnet is greater than the magnetic field intensity of permanent magnet, and electromagnet is contrary near the polarity of holding with permanent magnet;
B, separation permanent magnet and electromagnet are to certain distance;
C, disconnection electromagnet power supply, drop the magnetisable material of electromagnet absorption.
In technical scheme of the present invention, when permanent magnet absorption magnetisable material needs removal, adsorb the extreme of magnetisable material with the heteropole end with larger magnetic field intensity electromagnet near permanent magnet, be subject to the effect of larger suction, the magnetisable material adsorbed on permanent magnet will be seized fully by electromagnet, after electromagnet is removed, disconnect the power supply of electromagnet, electromagnet magnetic is disappeared, magnetisable material on electromagnet will drop naturally, thereby has realized the purpose of the complete removal of permanent magnet absorption magnetisable material.
The invention has the advantages that:
Given full play to the advantage separately of electromagnet and permanent magnet, while making in granular material tiny magnetisable material removal, become and be easy to, the removal effect is greatly improved.
The accompanying drawing explanation:
Fig. 1 is fundamental diagram of the present invention.
The specific embodiment:
As shown in Figure 1, the magnetisable material of a kind of permanent magnet absorption provided by the invention unloads eliminating method fully, and in figure, irony cylinder 3 is by stent support, and irony cylinder 3 inwalls are provided with annular permanent magnet 4, make cylinder outward for the n utmost point, interior be the s utmost point (also can on the contrary).An electromagnet be comprised of solenoid 5 and iron core 6 (being electromagnet) is set, and making the end near cylinder 3 is that the s utmost point, the other end are the n utmost point.
When cylinder 3 and permanent magnet 4 are rotated counterclockwise, will flow to granular material that glassware 1 sends here and fall to the side, upper left of cylinder 3, the magnetisable material in granular material by the absorption of cylindrical permanent-magnet body after, rotation is to a side of the right noncontact material.
Now that the electromagnet s Ghandler motion of energising is moving near the noncontact material side, the right to permanent magnet, due to the magnetic field intensity (10000GS) of the electromagnet magnetic field intensity (3000GS) much larger than permanent magnet, and electromagnet is contrary near the polarity of end with permanent magnet, and the material adsorbed on permanent magnet will be seized on the iron core that is adsorbed on electromagnet fully by electromagnet.Then electromagnet is removed to certain distance, disconnects the electromagnet power supply, the material of electromagnet absorption is dropped.
Repeat said process, just can be constantly by the magnetisable material complete discharge in the cylindrical permanent-magnet body.
