Automatic solvent aspirated powder feeder-dissolver

Abstract

Abstract A method for dissolving chemical powders in water to make lumpfree solutions is afforded by this invention. The invention provides a method and an apparatus whereby water solutions of chemical powders can be easily formed. The method used to accomplish these results consists of the following: 1. Supplying a quantity of water to water supply port. 2. Feeding chemical powders through an outlet and into the water supply port, said water supply port having a supply assembly and a suction assembly fitted with aspirators to prevent backsplash and to draw the chemical powder into the water through the water supply port. 3. Mixing the chemical powders in the water in the water supply port to form a premixed slurry. 4. Discharging the premixed slurry into a mixing tank. 5. Filling a mixing tank and actuating a mixing means and a timer when the tank is filled to form a chemical solution. 6. Transferring the mixed solution to a storage tank by means of a transfer pump. 7. Pumping the chemical solution from the storage tank through a discharge. The apparatus used to accomplish the above method comprises: 1. A feeding chamber having an outlet. 2. A water supply port, comprising: A. a suction assembly having ends, B. a supply assembly having ends, C. two aspirators adapted to fit said ends of said suction assembly and the supply assembly, D. an automatic valve positioned in the supply assembly, and E. a delayed actuated automatic valve positioned between the suction assembly and the supply assembly. 3. A mixing tank capable of holding a chemical solution, comprising: A. a mixing means for the tank, B. an upper liquid-level-sensing means to close the automatic valve and the delayed actuated automatic valve, C. a lower liquid-level-sensing means to open said automatic valve and said delayed actuated automatic valve, D. an inlet adapted to receive said aspirator of said supply assembly of said water supply port, and E. an outlet. 4. A transfer pump adapted to remove said chemical solution from said mixing tank through the outlet and deenergized by said lower liquid-level-sensing means of the mixing tank. 5. A storage tank adapted to receive the chemical solution from the transfer pump having a lower liquid-level-sensing means to actuate said transfer pump and having an outlet. 6. A metering pump being deenergized manually, and having an outlet for discharge of the chemical solution.
