ABSTRACT:
A centrifugal apparatus for removing salts from herbicide solutions is provided comprising an outer cylindrical casing for enclosing a vertically rotatable spin basket. The outer cylindrical casing consists of a top wall, vertical side walls and a bottom wall with open passages for throughflow of spent filter media from said spin basket. The top wall supports a means for applying filter media against the internal walls of the spin basket, a means for spraying feed slurry against the internal walls of the spin basket, a means for spraying solvent against the internal walls of the spin basket, and a vertically rotatable plowing means. The vertical side walls support an internal upper collection trough for collecting liquid overflow from the spin basket when the spin basket is rotated, and with the bottom wall of the casing forms an internal lower collection chamber for collecting filtrate which flows through the spin basket when the spin basket is rotated. The bottom wall of the centrifuge has means for supporting the spin basket within the casing.
Piping for transporting fluid collected from said upper overflow collection trough is also provided, as well as piping for transporting fluid collected from the lower collection chamber. A driving means for rotating the spin basket is also connected to the centrifugal. A method for removing salts from herbicide solutions utilizing the above apparatus is also provided.
