Abstract:
1. A feeder for dissolving a chemical and mixing it with a liquid, comprising: a hopper adapted to hold the chemical; a sieve plate adapted to retain the chemical above a bottom of the hopper and allow a solution of the chemical and the liquid to drain to the bottom of the hopper; a nozzle located in a center the hopper and extending up from the bottom of the hopper and through a central hole in the sieve plate, the nozzle including a multitude of jet ports arranged circumferentially about the nozzle and the jet ports arranged in multiple rows extending up along a length of the nozzle to direct a flow of the liquid out from the center of the hopper; a supply of the liquid to the nozzle to dissolve the chemical on contact with the liquid from the nozzle to form a solution; a solution basin; a rinse nozzle jet disposed in the solution basin and configured to direct a flow of the liquid across a bottom portion of the solution basin; an inlet liquid supply solenoid configured to control a flow of the supply of the liquid into the feeder, wherein the inlet supply solenoid is configured to direct the supply of the liquid to flow to both the nozzle and the rinse nozzle jet in response to being open; a chemical feeder solenoid configured to control the flow of the liquid from the inlet liquid supply solenoid to the nozzle, wherein the flow of the liquid to the nozzle is stopped in response to the chemical feeder solenoid being closed; a drain from the hopper into the solution basin; an outlet from the solution basin having an outlet valve which opens when a solution level in the solution basin rises; and an outlet float that actuates an outlet valve configured to maintain a substantially constant solution level in the solution basin.
