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 quartz sand process, be all the basic skills adopting permanent magnet absorption magnetisable material, remove magnetisable material contained in quartz sand.The magnet used has two kinds, and one is permanent magnet, and magnet is through special making, and magnetic can keep for a long time, usually can produce the magnetic field of Medium and low intensity (3000 ~ 4000GS), no longer needs other energy during absorption magnetisable material; Another kind is electromagnet, is wrapped on iron body with solenoid, and namely energising produces magnetic, and namely power-off magnetic disappear, and can produce the magnetic field of high strength (more than 10000GS), also can produce Medium and low intensity magnetic field, needs electric flux during absorption magnetisable material
.permanent magnetism and electromagnetism respectively have feature, cannot phase trans-substitution completely.
The magnetisable material wanting removal magnet to adsorb, is easy to electromagnet, and power-off makes magnetic disappear, and magnetisable material drops naturally; But very difficult to permanent magnet, more difficult when especially magnetisable material is fine particle, by taking various mechanical means, as with permanent magnet indirect attachment magnetisable material, this can reduce de-ferrous effect greatly, can't removal is tiny completely magnetisable material particle.
Summary of the invention
Object of the present invention is exactly the problem for solving the magnetisable material removal difficulty that permanent magnet adsorbs, the complete removal method of the permanent magnet adsorbent provided.
The technical solution used in the present invention is as follows:
A kind of complete removal method of permanent magnet adsorbent, is characterized in that comprising the following steps:
A, after permanent magnet absorption magnetisable material, by the magnetisable material that electromagnet adsorb near permanent magnet, the magnetic field intensity of electromagnet is greater than the magnetic field intensity of permanent magnet, and the close polarity of holding of electromagnet and permanent magnet is contrary;
B, separation permanent magnet and electromagnet are to certain distance;
C, disconnection electromagnet power supply, the magnetisable material that electromagnet is adsorbed drops.
In technical scheme of the present invention, when permanent magnet absorption magnetisable material needs removal, the extreme of magnetisable material is adsorbed near permanent magnet with the heteropole end with larger magnetic field intensity electromagnet, by the effect of larger suction, the magnetisable material that permanent magnet adsorbs will be seized completely by electromagnet, after electromagnet is removed, disconnect the power supply of electromagnet, electromagnet magnetic is disappeared, magnetisable material on electromagnet will drop naturally, thus achieves the object of the complete removal of permanent magnet absorption magnetisable material.
The invention has the advantages that:
Given full play to the respective advantage of electromagnet and permanent magnet, make to become during fine magnetic material removal in granular material to be easy to, removal effect is greatly improved.
Accompanying drawing illustrates:
Fig. 1 is fundamental diagram of the present invention.
Detailed description of the invention:
As shown in Figure 1, the complete removal method of magnetisable material of a kind of permanent magnet absorption provided by the invention, in figure, irony cylinder 3 is supported by support, and irony cylinder 3 inwall is provided with annular permanent magnet 4, make cylinder outward for n pole, interior be s pole (also can on the contrary).An electromagnet (i.e. electromagnet) be made up of solenoid 5 and iron core 6 is set, such that the one end near cylinder 3 is s pole, the other end is n pole.
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 after the absorption of cylindrical permanent-magnet body, rotates the side to the right noncontact material.
Now the electromagnet s Ghandler motion of energising is moved near the noncontact material side, the right to permanent magnet, because the magnetic field intensity (10000GS) of electromagnet is much larger than the magnetic field intensity (3000GS) of permanent magnet, and electromagnet is contrary near the polarity of holding with permanent magnet, and the material that permanent magnet adsorbs will be seized completely by electromagnet and be adsorbed on the iron core of electromagnet.Then electromagnet is removed to certain distance, disconnect electromagnet power supply, the material that electromagnet is adsorbed drops.
Repeat said process, just can constantly the magnetisable material in cylindrical permanent-magnet body be unloaded completely.
