Abstract
Method of adjusting a concentration of oil in a water-containing oil material which comprises determining a change in buoyancy exerted on a plummet suspended in the oil material and controlling the amount of water being supplied to the oil material according to the change in buoyancy, and apparatus therefor.
Claims19
An apparatus for adjusting the concentration of oil in a water-containing oil material, comprising:
- a tank for holding a water-containing oil material;
- stirring means in said tank for stirring said oil material in said tank;
- a plummet suspended in said oil material in said tank;
- a protective cylinder around said plummet in said tank, said protective cylinder being imperforate at the portions thereof opposite said plummet;
- a detector coupled to said plummet for detecting a change in buoyancy exerted on said plummet by said oil material in said tank;
- a water supply means coupled to said tank;
- a water supply-control valve coupled to said water supply means for controlling the supply of water to said tank via said water supply means;
- and
- signal generating means coupling said detector to said control valve for opening and closing said control valve responsive to said detecting of said change in buoyancy of said plummet, to thereby control said supply of water to said tank to adjust the oil concentration of said oil material in said tank.

- a tank for holding a water-containing oil material;
- stirring means in said tank for stirring said oil material in said tank;
- a plummet suspended in said oil material in said tank;
- baffle means provided adjacent said plummet in said tank for isolating said plummet from movements generated in said oil material in said tank during supplying of said water to said tank, or during stirring of said oil material by said stirring means, said baffle means being imperforate at the portions thereof opposing said plummet;
- a detector coupled to said plummet for detecting a change in buoyancy exerted on said plummet by said oil material in said tank;
- a water supply means coupled to said tank;
- a water supply-control valve coupled to said water supply means for controlling the supply of water to said tank via said water supply means;
- and
- signal generating means coupling said detector to said control valve for opening and closing in buoyancy of said plummet, to thereby control said supply of water to said tank to adjust the oil concentration of said oil material in said tank.
