May 1, 1923. AA-3,699 OVBROPHY METHOD FOR SEPARATING MAGNETIC MATERIALS Filed Sept. 28, 1921 USUW/W Patented May 1, 1923.
Umllm rim;-
OSCAR BBOPHY, O1? PHILADl-ELPHIA, PENNSYLVANIA.
METHOD FOR SEPARATING- IlIlTAGllllETIC MATERIALS.
Application filed September To (/11 whom t may cormcra zen ot the United States, residing: at Phila- (.lelphia, in the county oi? Philadelohia and State of Pennsylvania, have invented certain now and useful ljniprorenients in the lllethod For Soparatinp, lllagnetic Materials, of which i the tiollorving is a specification.
My invention relates to the separation oi material by means cl a magnetic separator, and my iljxBllillOD y iarticularly relates to the method oil? separating magnetic llflQilc ls having; different critical temperatures, by heating the metals suiliciently to render one of the metals temporarily non-ma netic and passing the metals through the 1; parator in this state, whereby the separator will cause the magnetic and HOIl YIiL, zetic metals to he deflected into diiii'r-vrent chazmels in the usual manner.
The object of my invention is to provide a method for separating metals, such as Monel metal from iron, whereby the loose particles of different materials in the -Form of borings, filings, lathe burnings and. the like, may be readily separated; and a further object of my invention is to provide an apparatus for carrying out the ZLlJOTB mentioned method of separating materials, comprising a heating device for heating the metals in Which exhaust steam may be utilized for this purpose at a low cost oi operating the apparatus.
In carrying out my invention, sufiicient heat may be derived from steam pipes, or a steam heated jacket, to render the Monel metal non-magnetic, as this metal ceases to be magnetic at two hundred and five degrees F., approximately.
Referring to the accompanying drawing, Fig, 1. is a vertical sectional view of a mag netic aerator embodying a heating: device, and F2 is a plan view of Fig, 1.
In the acconmanyinp; drawings in which like reference characters refer to like part 11. represents one form of a magnetic sepa tor, now in general use, Which comprises a frame 2 on which is mounted pulleys 3 and 4t, rotated in any suitable manner and around the pulleys extends an endless belt 5. The pulley l is a magnetic pulley and contains any suitable form of magnets 6, adapted to attract magnetic material, carried by the belt 5, around said pulley 4, sutlicient distance to cause it to be drawn out of the ve'a tioal line or path through, which the non 1921. Serial No. 503,883.
mage notic material. will fall from the bolt 5 and thus separate the two materials and deposit them in separate compartments 7 and 8,
i hopper 10 is positioned above the belt 5 for rec ring); the mingled n'iaterii-ll and (listriluitino' the same upon the belt V out my invention, I construct the hopper 11.0, with a jacket 12, which forms a chaml'ier 1 around the hopper 10. A steaul supply pipe i land an outlet pipe 15 are connected with the chan'lber ill of the hopper, whereby steam may be circulated through the chamber for heating the hopper l0, and the material as it passes through the hopper.
The hopper is positioned close to the mannctic pulley l so that the material will pass over the pulley before it cools.
lllonol metal, consisting essentially of copper and nickel, is new extensively used in the various manufactures, and it is desirable to save the large amount of Waste of this material in the form of borings and turninos, which have heretofore been discarded, due to the presence of the iron and steel min ed therewith, which rendered the Monel metal, containing such scrap metal, uneven in texture and diflicult to machine, due to the hard spots therein caused by the high percentage of iron.
By my novel method. of separating metals; Monel m eta], and metals of similar character, may be reclaimed from scrap containing iron and steel by heating the same sufiiciently to render one of the metals temporarily nonmagnetic and passing the mingled substances through a magnetic separator While heated,
I do not confine myselt to heating by ex haust steam, but may use any oi the Well known methods for heating.
Having; thus described my invention, I claim and desire to secure by Letters Patent:
1, The method of separating two magnetic substances by means of a magnetic separator, comprising the heating of the sub stances to a sufficient temperature to render one or? said substances non-magnetic with out change of composition and passing the substances through the separator While heated.
2. The method of separating two mag netic substances by means of a magnetic separator, comprising the heating of the substances to a suiiicient temperature to l DU HIS
render one of said substances temporarily non-magnetic Without change of composition, and passing the substances through the separator While heated.
3. The method of separating magnetic metals, comprising the heating of the mingled metals to a temperature which will render one of the metals non-magnetic without changing the composition and passing and passing the same through a magnetic separator While heated.
'5. The method of separating a substance composedof essentially copper and nickel from another metal such as iron, comprising the heating of the mingled substances without changing the composition to a temperature which will temporarily render the first named substance non-magnetic and passing the mingled substances through a magnetic separator whereby the iron will be acted upon by the magnet of the separator, and the first named substance will pass through the separator without being affected by the said magnet.
6. The method of separating two substances having different magnetic critical te nperatures, comprising heating the mingled substances withoutchanging the composition to a temperature which will render one of the substances non-magnetic without affecting the magnetic state of the other substance, and passing the mingled substances through a magnetic separator for separating the magnetic substance from the substance rendered temporarily non-magnetic by the increase of temperature.
In testimony whereof I aflix my signature.
