Abstract

A device for delivering chemical solutions into a liquid flow within a chemical dispensing unit, where said chemical solution is created by dissolving solid chemical contained within a chemical cartridge, the unit having a base member and housing connected into a fluid flow line such that liquid flows into the base member, into the housing and back out through the base member or through the top of the housing, the chemical dispenser device having an upper conduit member, an apertured midsection, a chemical containing lower cartridge and a coaxial tube extending through the cartridge, the cartridge having an intake aperture located on the upper portion of its side wall and a dispensing aperture on its top, such that a saturated chemical solution is formed in said cartridge and passes into the liquid flow through the dispensing aperture due to the pressure differential of the liquid flowing into the apertured midsection and out through either the upper conduit or through the coaxial conduit.

Claims13

Dependent claims

A chemical dispenser for use in a liquid flow conduit line comprising a base member adapted to be incorporated into said flow conduit line, said base member having an inlet opening adapted to receive an inlet conduit, an outlet opening adapted to receive an outlet conduit, a downflow opening communicating with said inlet opening, a centrally located upflow opening communicating with said outlet opening, and mating means adapted to receive a cylindrical housing, said cylindrical housing comprising an outer wall, closed bottom and open top, and adapted to mate with said mating means of said base member;

said chemical dispenser comprising an upper conduit segment connected to an apertured midsection segment connected to a lower chemical containing cartridge member connected to a lower tube member;
a coaxial conduit extending from within said upper conduit segment through said midsection segment and said cartridge member to said lower tube member;
said upper conduit segment comprising an open top and an open bottom, said open top adapted to sealingly mate with said upflow opening of said base member;
said apertured midsection segment having at least one flow opening to allow liquid to flow into said upper conduit segment;
said cartridge member comprising a closed bottom, a side wall containing at least one intake aperture positioned in the upper portion of said side wall, and a top containing at least one dispensing aperture, said bottom, top and side wall defining an interior and containing a chemical in solid form, whereby liquid enters said cartridge member through said intake aperture and contacts said chemical to dissolve said chemical and form a saturated chemical solution within said cartridge interior, and whereby said saturated solution exits said cartridge member through said dispensing aperture in response to liquid flow through said apertured midsection and upper tube segment;
and
said lower tube member adapted to sealingly abut said closed bottom of said housing.
