Abstract:
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; andsaid lower tube member adapted to sealingly abut said closed bottom of said housing.
