Abstract
A device for delivering chemical solutions into a liquid flow, where the chemical solution is created by dissolving solid chemical contained within a chemical dispenser cartridge, the dispenser cartridge having an intake aperture located on the upper portion of its side wall and a dispensing aperture on its removable cap member, such that a saturated chemical solution is formed in the cartridge and passes into the liquid flow through the dispensing aperture due to the pressure differential of the liquid flowing through a tubular filter, the dispenser cartridge being mounted within the tubular filter.
Claims20
A device for introducing a chemical solution into a flow of liquid, said device comprising a dispenser cartridge, cartridge retainer means and a tubular filter means;
- said dispenser cartridge comprising a closed bottom, a side wall containing at least one intake aperture positioned in the upper portion of said side wall, and a removable cap member containing at least one dispensing aperture, said bottom, cap member and side wall defining an interior and containing a chemical in solid form, whereby liquid enters said dispenser cartridge through said intake aperture and contacts said chemical to dissolve said chemical and form a saturated chemical solution within said dispenser cartridge interior, and whereby said saturated solution exits said dispenser cartridge through said dispensing aperture in response to liquid flow around said dispenser cartridge;
- said cartridge retainer means adapted to retain said dispenser cartridge within said tubular filter means and in fixed position relative to said tubular filter means.
A device for introducing a chemical solution into a flow of liquid within a filter apparatus, said filter apparatus comprising a tubular filter means, 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 conduit 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, and said device comprising:
- dispenser means comprising a dispenser cartridge and cartridge retainer means for retaining said dispenser cartridge, said dispenser cartridge comprising a closed bottom, a side wall containing at least one intake aperture positioned in the upper portion of said side wall, and a removable cap member containing at least one dispensing aperture, said bottom, cap member and side wall defining an interior and containing a chemical in solid form, whereby liquid enters said dispenser cartridge through said intake aperture and contacts said chemical to dissolve said chemical and form a saturated chemical solution within said dispenser cartridge interior, and whereby said saturated solution exits said dispenser cartridge through said dispensing aperture in response to liquid flow through said tubular filter means.
A device for introducing a chemical solution into a flow of liquid within a filter apparatus, said filter apparatus comprising a tubular filter means and a housing adapted to be incorporated into a flow conduit line, said housing having an inflow end with an inflow conduit adapted to receive an inlet conduit and an opposing outflow end with an outflow conduit adapted to receive an outlet conduit connected to a main body, such that liquid flow through said housing is generally in a single direction, said device comprising;
- dispenser means comprising a dispenser cartridge and cartridge retainer means for retaining said dispenser cartridge, said dispenser cartridge comprising a closed bottom, a side wall containing at least one intake aperture positioned in the upper portion of said side wall, and a removable cap member containing at least one dispensing aperture, said bottom, cap member and side wall defining an interior and containing a chemical in solid form, whereby liquid enters said dispenser cartridge through said intake aperture and contacts said chemical to dissolve said chemical and form a saturated chemical solution within said dispenser cartridge interior, and whereby said saturated solution exits said dispenser cartridge through said dispensing aperture in response to liquid flow through said tubular filter means.
