Patent number: 9540265Abstract: The present invention relates to a chemical feeder that includes a housing having a housing chamber, a sieve plate residing within the housing chamber, and a funnel residing on an upper surface of the sieve plate. The funnel includes upper and lower openings, an interior funnel space, and at least one funnel sidewall aperture.

Patent number: 9266757Abstract: A chemical feeder includes a support plate that is positioned within the housing chamber of the chemical feeder is described. The support plate includes a base plate having an upper surface that has one or more extensions that extend upward from the upper surface. The extensions can, with some embodiments, be in the form of arcuate extensions that can together define an impeller pattern or a spiral extension that defines a spiral channel. The upper surface of the base plate and/or the one or more extensions are adapted to support a solid chemical material thereon. The support plate further includes a plurality of arcuate channel apertures or spiral channel apertures that extend through the base plate. A feed liquid introduced into the housing chamber flows through at least one of the plurality of arcuate/spiral channel apertures and contacts the solid chemical material to form a treated liquid.Type: GrantFiled: November 5, 2014Date of Patent: February 23, 2016Assignee: AXIALL OHIO, INC.Inventor: Stanley R.

Patent number: 9260329Abstract: The present invention relates to a chemical feeder that includes a support plate that is positioned within the housing chamber of the chemical feeder, in which one or more extensions extend upward from an upper surface of the base plate of the support plate. The extensions can, with some embodiments, be in the form of peg extensions, arcuate extensions that can together define an impeller pattern, or a spiral extension. A distributor head having a plurality of distributor head apertures and at least one dome hole extends up through a support plate aperture in the base plate of the support plate, and distributes liquid horizontally and vertically relative to the base plate. The horizontally and vertically distributed liquid contacts a solid chemical material that is supported above the support plate, so as to form a treated liquid that includes dissolved chemical material.Type: GrantFiled: October 27, 2014Date of Patent: February 16, 2016Assignee: AXIALL OHIO, INC.Inventor: Stanley R.

The extensions can, with some embodiments, be in the form of peg extensions, arcuate extensions that can together define an impeller pattern, or a spiral extension. The support plate also includes a deflection plate that is positioned vertically above at least one support plate aperture that extends through the base plate. The deflection plate also includes at least one deflection plate hole therethrough. A first portion of liquid passing up through the support plate aperture is horizontally deflected by the deflection plate and interacts with the extensions. A second portion of liquid passing up through the support plate aperture passes vertically up through the deflection plate hole(s).Type: GrantFiled: October 27, 2014Date of Patent: February 16, 2016Assignee: AXIALL OHIO, INC.Inventors: Richard H.
