Abstract:
1. An adjustable chemical dispensing device for introducing a chemical solution into a flow of liquid, said device adapted to be received within a base member adapted to be incorporated into a 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 , adjustable chemical dispensing device comprising: an upper tube connected to a lower chemical dispensing chamber, said upper tube comprising an apertured midsection segment and 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 multiple flow openings to allow liquid to flow into said upper tube; said chemical dispensing chamber comprising a closed bottom, a top wall, at least one side wall, multiple intake refilling apertures, and multiple dispensing apertures, said bottom, top and at least one side wall defining an interior and containing a dissolvable chemical in solid or granular form, whereby refill liquid enters said chemical dispensing chamber through said intake apertures and contacts said chemical to dissolve said chemical and form a saturated chemical solution within said chemical dispensing chamber, and whereby said saturated solution exits said chemical dispensing chamber through said dispensing apertures in response to liquid flow through said apertured midsection and upper tube; said adjustable chemical dispensing device further comprising means for adjusting the rate of main liquid flow through said upper tube; means for adjusting the inflow rate of refill liquid into said chemical dispensing chamber; and means for adjusting the outflow rate of said saturated chemical solution into said upper tube and said main liquid flow.
