- the liquid mixture separation device of the present invention is a device for separating a specific substance from a liquid mixture of two or more substances having different entrainment characteristics with respect to an inner member such as a guide wall, which will be described later.
- the amount recovered from the mixed liquid is affected by the entrainment characteristics of the specific substance and the abundance/ratio of the specific substance. Viscosity, affinity, and the like are factors that affect the co-rotation characteristics. The higher the viscosity and the higher the affinity, the more difficult it is to fall off from the inner member and the easier it is to rotate. In particular, the high viscosity has a great effect on the ease of co-rotation.

Therefore, it is necessary to appropriately select the material according to the type of the liquid mixture, and for example, it is preferably made of metal or resin. Also, the sizes of the outer member and the inner member depend on the type of the mixed liquid to be separated and the amount of separation, and therefore may be determined as appropriate. Of the length in the axial direction of the inner member, the longer the portion above the liquid surface, the lower the separation speed, but the higher the separation precision.

- it preferably consists of one open end of a cylindrical member or an opening formed in the outer peripheral surface.
- the suction port is immersed in the mixed liquid, and the mixed liquid is continuously sucked from the suction port by the entrained force on the outer member and the inner member.
- the opening is preferably an opening extending in the axial direction. If the opening extends in the axial direction, when the mixed liquid separator is installed so that the axial direction intersects the liquid surface, even if the liquid surface fluctuates, the vicinity of the liquid surface will be positioned at the opening. It becomes possible to continuously inhale the liquid mixture containing the substance floating on the surface of the liquid through the opening.

By doing so, it is possible to prevent it from flowing out from places other than the specific substance discharge part. In addition, cylindrical parts are easy to process and inexpensive, so they are readily available. Furthermore, when a plate-like body is used as the transfer means in the later-described discharging means, it is preferable that the specific substance receiving portion is cylindrical. As will be described later, the plate rotates with respect to the specific substance receiving portion, so if the specific substance receiving portion is not cylindrical (for example, rectangular), there will be places where the plate cannot reach, and the specific substance will not be discharged. may occur.
- the specific substance discharge unit is not particularly limited in its form as long as it can discharge the specific substance accumulated in the specific substance receiving unit.

- the specific substance accumulated in the specific substance receiving portion can be pushed by the plate-like body and collected in the discharging portion, and can be discharged efficiently. Moreover, even if the specific substance is a substance that tends to solidify when left for a long period of time, it can be prevented from solidifying while remaining in the specific substance receiving portion because the plate-like body allows the substance to flow.
- the plate-shaped bodies there are no particular limitations on the size or number of the plate-shaped bodies, as long as they have a surface that can push a specific substance.
- the plate-like body may be a metal plate, a resin plate having a certain degree of rigidity, or an elastic body such as a rubber plate that is in elastic contact with the specific substance receiving portion.

- the centrifugal force generated at this time is as weak as about 0.002 to 0.9G. Therefore, the rotation is not so fast as to generate a strong centrifugal force that pushes the material against the inner peripheral surface of the outer member or keeps it away from the inner member.
- 30 to 120 rpm is preferable.
- the outer peripheral side of the inner member has two (n) or more helical guide walls that guide a specific substance from one end of the outer member to the other end by relative rotation of the outer member and the inner member. By relative rotation of the outer member and the inner member, the specific substance is separated by sending it along the guide wall to the other end.

- the valley width Vw is the distance between adjacent guide walls among two or more guide walls arranged side by side.
- the values of Mw and Vw can be evaluated over the entire guide wall, it is preferable to evaluate the values of the portions located near and above the liquid surface.
- the values of Mw and Vw are not the same over the range of the guide wall to be evaluated, they can be evaluated as average values.
- the values of Mw and Vw fall within the range of 50 to 150% when the average value is 100% in an arbitrary 90% or more portion of the length of the range to be evaluated in the axial direction. More preferably, it falls within the range of 50-150% over the range evaluated.
- the lower limit of this range can be 70% and 90%, and the upper limit can be 130% and 110%.

That is, it is preferable that the outer member has a cylindrical inner peripheral side and the inner member has a helical guide wall on its outer peripheral side.
- the inner member having a helical guide wall on the outer peripheral side may be a male screw, a spring, or a helically wound wire. At this time, the specific substance is entrained around the cylindrical inner peripheral surface of the outer member and the guide wall (male screw) of the inner member due to its adhesive force, frictional force, and the like.
- the inner peripheral side of the outer member or the outer peripheral side of the inner member may be formed into a raised or brush-like uneven surface.
- powder such as metal scraps is preferable because it easily adheres to the uneven surface.
- At least one of the inner peripheral side of the outer member and the outer peripheral side of the inner member may be a hydrophilic or hydrophobic surface, or may be a magnetic surface.

- cutting in the axial direction is usually cut in the radial direction.
- the cut surface 111 is oriented in a direction that hinders the flow of the inhaled liquid mixture. Therefore, the 180° opening is provided with an edge portion (not shown) having a thin tip on the side where the liquid mixture is sucked. By forming the edge portion with the axial opening end surface 111 as an inclined surface that inclines toward the inner peripheral surface side, the liquid mixture flows smoothly.

- the geared motor 30 is connected to one end of the inner member 2 and drives the inner member 2 to rotate.
- an inverter is incorporated in the circuit that controls the geared motor 30 to control the frequency of the motor and set the rotation speed of the inner member 2 arbitrarily.
- the recovery rate of a specific substance was evaluated.
- it is expected to improve the collection speed by changing the shape of the inner member. Therefore, in this embodiment, it was decided to examine the recovery speed instead of the separation speed. Since it is not essential to use a mixed liquid in order to evaluate the recovery speed, VG68 oil was used alone as a specific substance in place of the mixed liquid.
- the shape of the inner member was changed as shown in Table 1 and tested. The inner member was rotated at 60 rpm and evaluated by recovery of the specified material per 10 minutes.
- Guide walls with leads shown in Table 1 were provided at pitch intervals equal to the number of threads.
