Abstract

A magnetic separator apparatus having a configuration of barium ceramic magnets impregnated into polypropylene bars interspersed onto a conveyor belt which passes through an aqueous solution containing unwanted magnetic particulate. A plurality of spaced-apart magnet pairs embedded in each polypropylene bar are configured to provide maximum field penetration and holding strength of the magnets. Particulate attracted to the plurality of magnet pairs are scraped from the conveyor belt into a collection drawer.

Claims

1. An apparatus for separating unwanted magnetic particulate from an aqueous solution, said apparatus comprising:

a plurality of spaced-apart magnetic means disposed upon a conveyor belt means for attracting said magnetic particulate;

said conveyor belt means disposed within said aqueous solution and configured for movement therethrough;

each of said plurality of magnetic means constructed of polyproylene impregnated with a like plurality of pairs of magnetic bars disposed on each side of a longitudinal axis of said conveyor belt means; and

scraper means fixedly attached to said conveyor belt means for removing said particulate from said plurality of magnetic means for deposit into collection means.

2. The apparatus recited in claim 1, wherein each of said plurality of pairs of magnetic bars comprises:

a first barium ceramic magnet having a top and bottom surface;

a second barium ceramic magnet having a top and bottom surface; and

with said bottom surface of said first barium ceramic magnet disposed abutably of said top surface of said second barium ceramic magnet, so that the South Pole of said first barium ceramic magnetic is aligned and contiguous with the South Pole of said second barium ceramic magnet.

3. The apparatus recited in claim 2, wherein said plurality of spaced-apart magnetic means are disposed uniformly upon said conveyor belt means.

4. The apparatus recited in claim 2, wherein each of said sets of pairs of said plurality of pairs of magnetic bars embedded in each of said plurality of spaced-apart magnetic means is disposed symmetrically of said longitudinal axis of said conveyor belt means.

5. An apparatus for separating unwanted magnetic particulate from an aqueous solution, said apparatus comprising:

a plurality of uniformly spaced-apart magnetic means disposed upon a conveyor belt means for attracting said magnetic particulate;

said conveyor belt means disposed within said aqueous solution and configured for movement therethrough;

each of said plurality of magnetic means constructed of polypropylene impregnated with a like plurality of pairs of magnetic bars disposed on each side of a longitudinal axis of said conveyor belt means;

each of said plurality of pairs of magnetic bars having;

a first barium ceramic magnet having a top and bottom surface;

a second barium ceramic magnet having a top and bottom surface; and

with said bottom surface of said first barium ceramic magnet disposed abutably said top surface of said second barium ceramic magnet, so that the South Pole of said first barium ceramic magnetic is aligned and contiguous with the South Pole of said second barium ceramic magnet; and

scraper means fixedly attached to said conveyor belt means for removing said particulate from said plurality of magnetic means for deposit into collection means.

6. The apparatus recited in claim 5, wherein said plurality of spaced-apart magnetic means are disposed uniformly upon said conveyor belt means.

7. The apparatus recited in claim 5, wherein each of said sets of pairs of said plurality of pairs of magnetic bars embedded in each of said plurality of spaced-apart magnetic means is disposed symmetrically of said longitudinal axis of said conveyor belt means.

8. An apparatus for separating unwanted magnetic particulate from an aqueous solution, said apparatus comprising:

a plurality of spaced-apart magnetic means uniformly disposed upon a conveyor belt means for attracting said magnetic particulate;

said conveyor belt means disposed within said aqueous solution and configured for movement therethrough;

each of said plurality of magnetic means constructed of polypropylene impregnated with a like plurality of pairs of magnetic bars disposed on each side of a longitudinal axis of said conveyor belt means;

each of said plurality of pairs of magnetic bars having;

a first barium ceramic magnet having a top and bottom surface;

a second barium ceramic magnet having a top and bottom surface; and

with said bottom surface of said first barium ceramic magnet disposed abutably of said top surface of said second barium ceramic magnet, so that the South Pole of said first barium ceramic magnetic is aligned and contiguous with the South Pole of said second barium ceramic magnet;

each of said sets of pairs of said plurality of pairs of magnetic bars impregnated in each of said plurality of spaced-apart magnetic means is disposed symmetrically of said longitudinal axis of said conveyor belt means; and

scraper means fixedly attached to said conveyor belt means for removing said particulate from said plurality of magnetic means for deposit into collection means.
