Apparatus and method for installation of a fluid dispenser in wastewater

Apparatus for installing a fluid dispenser within wastewater of a wastewater compartment in submerged relation, the fluid dispenser having an electrical motor, a shaft driven by said motor, a propeller on the end of said shaft, a vacuum tube about said shaft, a collar about said vacuum tube adjacent said propeller, an orifice between said collar and propeller for dispersal of a treating fluid therefrom upon rotation of said propeller, and sharp opposed cutting edges on said propeller and said collar on opposed sides of said orifice for cutting solid particles entering said orifice;

• said apparatus comprising:
• a generally vertically extending post mounted within said wastewater compartment for extending above the level of wastewater in said compartment;
• a sliding support bracket mounted on said post for sliding movement and having said fluid dispenser mounted thereon for sliding movement with said support bracket;
• a stop on said post to block the downward sliding movement of said sliding support and fluid dispenser;
• and
• pivot means on said sliding support to effect pivoting of said sliding bracket and fluid dispenser to a desired direction of said fluid dispenser upon contact of said support bracket with said stop.

A fluid dispenser for dispensing a treating agent within wastewater in a wastewater compartment;

• said fluid dispenser comprising:
• a body having a generally cylindrical housing;
• an electric motor within said housing;
• a shaft driven by said motor;
• a propeller on the end of said shaft;
• a vacuum tube about said shaft;
• a collar about said vacuum tube adjacent said propeller;
• an orifice between said collar and propeller for dispersal of a treating agent therefrom upon rotation of said propeller;
• and
• sharp opposed cutting edges on said propeller and said collar on opposed sides of said orifice for cutting solid particles entering said orifice, at least one of said cutting edges being serrated for cutting of said solid particles.

A method for installing a fluid dispenser in a submerged relation in wastewater within a wastewater chamber for dispersing a fluid treating agent within the wastewater;

• said method comprising the following steps:
• mounting a generally vertical support post within the wastewater chamber;
• mounting a fluid dispenser on a sliding bracket for sliding movement of the fluid dispenser and bracket along said post;
• constructing said sliding bracket of a pair of spaced parallel side plates and mounting a support angle on one of the side plates for the fluid dispenser;
• mounting the fluid dispenser on the support angle for movement with the sliding bracket;
• mounting said sliding bracket and fluid dispenser on the upper end of the post above the level of wastewater in the wastewater chamber with the post being received by the bracket in telescoping sliding relation;
• lowering said sliding bracket and fluid dispenser in sliding relation downward along said post to a stop on said post at a desired location of the fluid dispenser for blocking further downward sliding movement of said bracket and fluid dispenser;
• and
• pivoting said sliding bracket and fluid dispenser when said bracket engages said stop into a desired direction of said fluid dispenser for dispensing the treating agent within the wastewater.
