In-line apparatus for dissolving a solid in a liquid
First Claim
1. An apparatus for dissolving a solid in a liquid flowing in a liquid line, comprising in combination:
- a tank for holding the solid to be dissolved;
an intake line for connecting the liquid line in fluid communication with the tank for bringing liquid from the liquid line into the tank wherein the tank end of the intake line extends downwardly into the tank;
a return line for connecting the tank in fluid communication with the liquid line for returning the liquid from the tank into the liquid line wherein the tank end of the return line is inserted an adjustable depth into the tank whereby liquid passes through the tank from the intake line to the return line over the exposed surface of the solid, dissolving the solid and the rate of dissolving the solid can be adjusted by adjusting the depth of the tank end of the return line; and
a substantially vertical pipe extending from the bottom of the tank substantially to the top of the downwardly extending portion of the intake line encircling the downwardly extending portion of the intake line, restable on the bottom of the tank, the wall of the intake line forming at least one hole below the top of the encircling pipe.

Abstract
An apparatus for dissolving a solid in a liquid flowing in a liquid line is disclosed. The apparatus includes a tank for holding the solid to be dissolved, an intake line for bringing liquid from the liquid line into the tank, and a return line for returning the liquid from the tank into the liquid line. In one arrangement, the return line is inserted an adjustable depth into the tank allowing adjustment of the water flow across the solid to be dissolved within the tank. An intake connector terminates the liquid line end of the intake line. The intake connector extends into the liquid line and forms an opening facing upstream in the liquid line. A return connector terminates the liquid line end of the return line. The return connector extends into the fluid line and forms an opening facing downstream in the liquid line. A hand operable valve and a flow meter are connected in-line with the intake line. The tank end of the intake line extends downwardly into the tank and is encircled by a substantially vertical pipe which rests on the bottom of the tank. The wall of the intake line forms at least one hole below the top of the encircling pipe for venting air from the line. In an arrangement especially suited for being a swimming pool chlorinator, a removable substantially vertical cartridge pipe with a plurality of apertures along its length rests on the bottom of the tank for retaining chlorine tablets. A special lid including a groove for receiving a tool shaft across the top of the lid engages a threaded aperture above the cartridge pipe.
