Thereafter, the to-be-treated liquid formed by the puffing can be pressurized and sent to the outside. As a result, the bubble can be subjected to pressure fluctuations and shocks to effectively perform the bubble treatment.

According to a fifth aspect of the present invention, in the expanded body according to any one of the first to fourth aspects, the hole of the lower disk is brought into contact with the foam on the liquid to be treated, And is disposed at a position where air above the treatment liquid is sucked.

According to the fifth aspect of the present invention, by arranging the hole of the lower disk of the endoplasmic reticulum in contact with the foam on the liquid to be treated and further inserting the hole of the upper disk at a position where the air above the liquid to be processed is sucked, The air sucked from the hole of the upper disk can be collected in the foam sucked from the hole of the disk and centrifugal force can be applied to the foam in this state. As a result, it is possible to surely disperse the light foam which is generated by the incorporation of the surfactant.

According to the above aspect of the present invention, there is provided an endoplasmic reticulum comprising a plurality of blades provided between a rotating upper disk and a lower disk to form a compartment at a predetermined pitch in a circumferential direction, And a hole communicating with the center of the compartment was formed on the lower disk. Thereby, for example, when the lower disk is brought into contact with the foam on the liquid surface of the liquid to be treated and the upper disk is placed in the air, when the upper and lower disks are rotated, the bubble is sucked from the hole of the lower disk , And air is sucked from the holes of the upper disk. At this time, the air sucked from the hole of the upper disk can be collected in the foam sucked from the hole of the lower disk, and in this state, the centrifugal force is applied to the foam. As a result, the air-entrained foam bubbles in the compartment and the surface area of the foam increases, so that partial cracks are generated in the foam, and the depressions tend to occur.

In other words, according to the embodiment of the present invention, the air bubbles sucked from the holes of the lower disk are combined with the air sucked from the holes of the upper disk, and centrifugal force is applied to the bubbles, It is also possible to reliably release light foam. In addition, economical vesicle treatment which does not require additional treatment such as addition of additives for vesicles or water spraying becomes possible.

The rotary shaft 12 is provided so as to be movable up and down on the mounting table 11 along the axis 12A so that the rotary shaft 12 is moved from the upper position indicated by the two- . ≪ / RTI >

Next, the elastomer 20 according to the first embodiment of the present invention, which is mounted on the tip of the motor rotation shaft 12 of the defoaming device 10, will be described with reference to a plan view of Fig. 2A and a front sectional view of Fig. 2B .

The vesicle 20 has a plurality of blades (not shown) that form a compartment 23 at a predetermined pitch along the circumferential direction between an upper disk 21 and a lower disk 22 provided in a positional relationship parallel to each other 24 are provided. These blades 24 are arranged at a constant pitch so as to divide the space in the vertical direction in the figure so as to connect the upper and lower disks 21 and 22 so that the compartment 23 is formed between the blades 24 have.
