TWO-PART LIQUIDS SEPARATION DEVICE AND LIQUID/SOLID SEPARATION DEVICE

PURPOSE:To provide a technology for a simple structure which can control the position of a boundary surface. CONSTITUTION:A two-part liquids separation device 1 comprises a load measuring section 3 for measuring the weight of a container 2 containing its content and a boundary surface control section 10 for receiving the measurement signals from a measurement section 3, changing the liquid discharge ratio between a first discharge pipe 5 and a second discharge pipe 6 and retaining a boundary surface 13 between first liquid 11 and second liquid 12 on the given positions. In the case the liquid of larger specific gravity is specified as the first liquid, the total weight is increased when the boundary surface is raised higher than the given position. The discharge ratio of first liquid, therefore, is increased and the boundary surface is lowered by the control section. In the case of being vice versa, the discharge ratio of second liquid is increased or the discharge ratio of first liquid is decreased.
