第２図中Ａ部の既略斜視図である。Furthermore, since the inner cylinder 8 is provided with a coarse-grained layer 10 using packing, the oil-water separation capacity is doubled. Although the present invention has been specifically explained above based on one embodiment, the liquid to be separated is not limited to oil and water, but any liquid can be used in order to separate a mixture of liquids with different specific gravities. It is available. That is, in the present invention, an inner cylinder and an outer cylinder are arranged concentrically, and the space between the inner cylinder and the outer cylinder is divided into upper and lower parts by a partition plate to form an upper separation chamber and a lower separation chamber, and the mixing A liquid inlet is provided in the circumferential direction of the outer cylinder of the lower separation chamber, an outlet for a liquid with a lighter specific gravity is provided above the upper separation chamber, an outlet for a liquid with a higher specific gravity is provided below that, and an outlet for a liquid with a higher specific gravity is provided in the upper part of the inner cylinder. forming a coarse layer of liquid droplets with a light specific gravity, and forming a gravity separation layer between the inner cylinder and the outer cylinder of the upper separation chamber by a plurality of inclined plates installed in a spiral shape. The present invention provides a mixed liquid separation device characterized by the fact that the inner cylinder is equipped with a coarse grain layer, which doubles the mixed liquid separation capacity, and the mirror swash plate is separated from the inner cylinder and the outer cylinder. Since it is installed in a spiral shape between the tube and the cylinder, the distance is long, so the mixed liquid separation effect is increased.Since the mixed liquid inlet is installed in the circumferential direction, it has the function of separating suspended solids, and the range of applications is widened. Since the forehead swash plate is attached in a spiral shape, there is no dead space, and the device can therefore be made more compact.
