Abstract:
PROBLEM TO BE SOLVED: To provide a cistern adapted so that the liquid stored therein may not form a vortex when the liquid is stirred to uniformize its concentration or temperature distribution.
SOLUTION: The cistern 1 is partitioned with a partition 11 of a specified height into a liquid storage tank 12 for storing a liquid L and a stirring tank 13 for stirring the liquid L. During the operation of the cistern 1, a stirrer 15 held in the stirrer holder 16 of the tank 13 is rotated to stir the liquid L stored in the tank 13, while the liquid L flowing from the tank 13 into the holder 16 is delivered to a liquid feed passage 17 by rotating the stirrer 15. The liquid L delivered to the passage 17 flows into the tank 12 through a liquid feed port 14.
