ELECTROMAGNETIC SEPARATOR.
Specification of Letters Patent.
Patented Nov. 6, 1917.
Application filed June 20, 1914. Serial No. 846,292.
To all whom it may concern:
' Be it known that I, CLARK T. HENDERSON, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Electromagnetic Separators, of which the following is a full, clear, conclse, and exact description, reference being had to the accompanying drawing, forming a part of this specification.
This invention relates to electromagnetic separators.
One of the objects of the invention is to provide improved means for extracting free magnetic particles from flowing substances.
A further Object is to provide an improved electro-magnetic separator wherein the material treated flows in a directionparallel to the lines of magnetic flux and wherein the poles of the magnet present a large area for attracting and collecting the magnetic content.
Further objects and advantages will appear hereinafter in connection with the description of the accompanying drawing, which illustrates, partially in section, an embodiment of the invention designed more particularly for removing magnetic particles suspended in fluids, such as slip used in the manufacture of china, pottery and porcelain.
The device comprises, in general, a magnet winding 1 coiled about a tubular sleeve 2 which constitutes a passage for the material treated and which is provided with two or more transversely disposed apertured members magnetized when the winding is energized. The members 3 are Spaced along the interior of the sleeve and are provided with numerous openings extending in a direction parallel to the flow of the material treated and to the magnetic lines of force. The faces of members 3 also alternate in polarity so that, in efiect, the device includes two or more subsidiary magnets all induced by the large winding 1.
Referring more specifically to the drawing, the Same shows the winding 1 wound on a central sleeve 2 of non-magnetic material and inclosed in a magnetic iron frame 4. The frame 4 comprises similar sections bolted together and located axially of the sleeve 2 by exterior flanges on the latter. The ends of the sleeve are preferably extended beyond the ends of the winding and are provlded with threaded reducing bushmgs 5 which enable the device to be connected in a pipe line. The apertured members 3 span the, sleeve 2 and are supported therein between alternate magnetic rings 6 and non-magnetic rings 7. The rings 6, 7 and the members 3 are retained within the sleeve between a shoulder 8 at one end of the latter and a threaded tap 9 at the other. The apertured members 3 preferably comprise relatively coarse Wire screens or perforated metal plates. It is to be understood, however, that other forms of magnetic members may be employed, if desired.
The device is designed to be installed in upright position and connected with the flllld supply so that the latter enters the lower end of the sleeve 2 and emerges from the device at its upper end. In this manner the flow of the liquid is substantially uniformat all points within the sleeve, and contact of the material with some exposed portion of the screens or plates 3 is practically insured. When the winding 1 is energized the screens are strongly magnetized and attract the free magnetic particles in the material and thus separate the same from the remainder of the flowing mass.
In operation, the material may be passed through the device until the accumulation of the magnetic particles on the attracting screens or plates clogs the apertures in the latter to a degree Which impedes further passage of the material. The device may be readily cleaned, either by depriving the winding 1 of current and connecting the lower bushing 5 to a waste pipe, and then flushing the sleeve by pouring water into the upper end thereof, or by removing the tap 9 andthen taking out the screens and cleaning the same while removed.
