PURPOSE:To rapidly, accurately and automatically prepare a large amount of various chemical solutions, by a method wherein the bottom parts of plural chemical solution tanks and nozzles are connected by connection pipes and a predetermined amount of the chemical liquids are discharged from the nozzles while said nozzles are respectively raised and fallen by a control apparatus. CONSTITUTION:The bottom parts of chemical solution tanks 1, 1', 1'' are connected to nozzles 5, 5', 5'' by hollow flexible connection pipes 2, 2', 2'' while the nozzles 5, 5', 5'' are respectively raised and fallen by rising and falling apparatuses 3, 3', 3''. when motors 7, 7', 7'' are respectively rotated in a predetermined amount by the signal of an operation control apparatus 8 and the nozzles 5, 5', 5'' are fallen to positions 25, 25', 25'', the liquid levels in the chemical solution tanks 1, 1', 1'' are fallen from positions 9, 9', 9'' to position 10, 10', 10'' and the solutions in oblique line parts A, A', A'' are discharged to a preparation tank 4 from the nozzles 5, 5', 5'' and can be stirred and mixed in a predetermined ratio. |
