Abstract
A dispense device includes a dispense head and threaded canister. A chemical container assembly disposed within the canister includes a support column which telescopically receives a chemical container. The chemical container includes inlet and outlet holes to allow a flow through the container to come into contact and subsequently dissolve chemical treatment material disposed within the container. The support column engages the dispense head to aid in defining the separation distance between the dispense head and the outlet hole of the chemical container.
Claims28
Apparatus for insertion into a liquid flow line for dispensing a soluble chemical into the liquid flowing through the flow line comprising:
- a dispense head member including an inlet and an outlet and defining a flow passageway coupling the inlet and the outlet;
- a canister engageable with said dispense head member defining a hollow interior cavity;
- said dispense head flow passageway including flow entry means for directing fluid flow into said hollow interior cavity and flow exit means for directing fluid flow out of said hollow interior cavity;
- the dispense head member and the canister having cooperating means for removably attaching the dispense head to the canister;
- a chemical holding container adapted to fit within said canister;
- said chemical holding container having opposed upper and lower ends and defining inlet and outlet flow pathways at its upper end;
- and
- said chemical holding container further including a cap consisting essentially of a unitary monolithic body that includes both a center portion defining socket means for connection to said dispense head and an outer portion that substantially covers the entire upper end of the chemical holder container so as to bring said outlet flow pathway of said chemical holding container in flow communication with the flow passageway of said dispense head.
A dispensing device for dispensing a chemical agent into a fluid flow, comprising:
- a dispense head having inlet and outlet means for coupling to said fluid flow and defining a flow passageway coupling said inlet and said outlet means;
- a canister engageable with said dispense head and defining a hollow interior cavity;
- said flow passageway in said dispense head including flow entry means for directing fluid flow into said hollow interior cavity and flow exit means for directing fluid flow out of said hollow interior cavity of said canister;
- a chemical holding container within said hollow interior cavity of said canister, in contact with the fluid flow;
- said chemical holding container having a tubular body with opposed upper and lower ends and defining a hollow, chemical-receiving interior and said chemical holder container further defining inlet and outlet flow pathways at its upper end;
- said tubular body including an inlet aperture portion adjacent its upper end;
- and
- a cap enclosing the upper end of said tubular body, said cap consisting essentially of a unitary monolithic body that includes both a center portion defining socket means extending into said tubular body hollow interior and providing at least one outlet aperture for flow connection to said flow exit means and a second outer portion that substantially covers the entire upper end of the chemical holder container.
