Chemical feeder
First Claim
1. Apparatus for feeding liquid soluble treatment matter into a liquid circulating system comprising means defining a container, a partition dividing said container internally into an upper compartment and a lower compartment, said upper compartment receiving a supply of said liquid treatment matter supported upon said partition, means for introducing liquid solvent within said lower compartment, orifice-defining means in said partition through which liquid introduced into said lower compartment rises into said upper compartment for dissolving said treatment matter and through which means the developed liquid solution flows into said lower compartment, a vertically presented liquid-solution discharge conduit open at the upper and lower ends thereof provided in said lower compartment, said lower compartment having a bottom opening, said conduit engageable in the lower end portion thereof within said last mentioned opening, and means effecting communication between the lower compartment and the upper end of said conduit.

Abstract
A chemical feeder comprising a container having an internal divider for developing an upper compartment for supporting a supply of treatment chemical and a lower compartment for receiving the liquid solvent with orifices in said divider for permitting the liquid to rise upwardly for dissolution of the treatment material. First and second weirs of different heights are provided in said container for controlling the level of liquid in the upper compartment and, hence, the concentration of the solution formed with control means for permitting optional usage of said weirs. A housing retaining a float valve supportingly receives the lower portion of said container and is in communication therewith for accepting the formed solution; there being a discharge outlet in said housing controlled by a needle valve integral with said float valve. Control for the level of liquid in said container is provided.

- 1. Apparatus for feeding liquid soluble treatment matter into a liquid circulating system comprising means defining a container, a partition dividing said container internally into an upper compartment and a lower compartment, said upper compartment receiving a supply of said liquid treatment matter supported upon said partition, means for introducing liquid solvent within said lower compartment, orifice-defining means in said partition through which liquid introduced into said lower compartment rises into said upper compartment for dissolving said treatment matter and through which means the developed liquid solution flows into said lower compartment, a vertically presented liquid-solution discharge conduit open at the upper and lower ends thereof provided in said lower compartment, said lower compartment having a bottom opening, said conduit engageable in the lower end portion thereof within said last mentioned opening, and means effecting communication between the lower compartment and the upper end of said conduit.
- 12. Apparatus for feeding liquid soluble treatment matter into a liquid circulating system comprising means defining a container, a partition dividing said container internally into an upper compartment and a lower compartment, said upper compartment receiving a supply of said liquid treatment matter supported upon said partition, means for introducing liquid solvent within said lower compartment, orifice-defining means in said partition through which liquid introduced into said lower compartment rises into said upper compartment for dissolving said treatment matter and through which orifice-defining means the developed liquid solution flows into said lower compartment, adjustable means permitting discharge of the developed liquid solution from the lower compartment after the liquid solution has risen to a predetermined level within said upper compartment, and a tubular weir provided within said container in surrounding relationship to said adjustable means allowing discharge of the liquid solution from the upper compartment and having its upper end terminating in immediate proximity to the upper end of said container.
- 14. Apparatus for feeding liquid soluble treatment matter into a liquid circulating system comprising means defining a container, a partition dividing said container internally into an upper compartment and a lower compartment, said upper compartment receiving a supply of said liquid treatment matter supported upon said partition, means for introducing liquid solvent within said lower compartment, orifice-defining means in said partition through which liquid introduced into said lower compartment rises into said upper compartment for dissolving said treatment matter and through which orifice-defining means the developed liquid solution flows into said lower compartment, said lower compartment having a bottom opening, said partition having an opening aligned with said lower compartment bottom opening, a vertically disposed open-ended conduit engaged in said lower compartment bottom opening and adapted for selected vertical positioning with respect to said last mentioned opening, an elongated weir provided within said container in encircling relationship to said conduit, the upper end of said weir being located spacedly above the upper end of said conduit in proximity to the upper end of said container, said weir having an aperture adjacent the upper end thereof for flow therethrough of liquid solution when the level of such within said upper container reaches such height, and means provided within said lower compartment above, and concentric with said lower compartment bottom opening engaging the lower end of said weir.
- 16. Apparatus for feeding liquid soluble treatment matter into a liquid circulating system comprising means defining a container, a partition dividing said container internally into an upper compartment and a lower compartment, said upper compartment receiving a supply of said liquid treatment matter supported upon said partition, means for introducing liquid solvent within said lower compartment, orifice-defining means in said partition through which liquid introduced into said lower compartment rises into said upper compartment for dissolving said treatment matter and through which orifice-defining means the developed liquid solution flows into said lower compartment, said lower compartment having a bottom opening, an open-ended conduit engaged within said last mentioned opening for vertical adjustability relative to said lower compartment permitting discharge of the developed liquid solution from the lower compartment after the liquid solution has risen to a predetermined level within said upper compartment, a tubular weir provided within said container for projection upwardly therein, means engaging the lower portion of said weir within said lower compartment, said weir being in surrounding relationship to said conduit, thereby shielding same from direct contact with ambient solution being formed in said upper compartment, the upper end portion of said weir terminating in relative proximity to the upper end of said container whereby liquid solution from the upper end portion of said upper compartment may discharge into said weir for alternate flow into said conduit.
