US 4,784,757 A · Solid material separator

Abstract

Apparatus for the separation of solid materials of different specific gravities comprising a vertical separator tube having a material inlet port, a light material discharge port located above the inlet port, and a heavy material discharge port located below the inlet port; a holding tank having a top opening for receiving the solid materials to be separated and a bottom opening connected to the inlet port of the separator tube by a feeder tube; a pressurized water source, as by a pump; and a conduit connecting the water source to the separator tube at or below the heavy material discharge port. The holding tank is located at such a height as to allow water coming into the tank from the separator tube to reach a predetermined static level within the tank. The heavy material discharge port is located substantially below the water static level in the tank and adjacent the pressurized water intake so that heavy material may be rapidly removed by water moving at a high velocity.

Dependent claims

Apparatus for the separation of mineral ores of differing specific gravity comprising:

a vertically oriented separation tube, said separation tube provided with an unobstructed solid material inlet port;
one or more light material discharge ports located above said inlet port;
a stand pipe at its uppermost end, said stand pipe extending above the uppermost discharge port;
and one or more unobstructed heavy material discharge ports located below said inlet port for rapidly removing heavy material by means of a high velocity stream of water;
pressurized water means;
a pressurized water conduit connected to said pressurized wate means and connected to and in fluid communication with said separation tube below said material inlet port;
and
a holding tank having a top opening for introduction of solid materials and a bottom opening in unobstructed fluid communication with said solid material inlet port of said separator tube for transfer of solid material to said separator tube by gravity from said holding tank and transferring water from said separator tube to said holding tank, said top opening of said holding tank located above the top light material discharge port of said separator tube for maintaining a water level in said tank above said light material discharge port.
