Description

The present invention relates to a nanobubble generator formed by connecting a plurality of blades.

When a large number of chips, such as a fan or rhombus, are arranged in a spiral in a casing and a liquid is flowed between them, the liquid collides with the tip of the chip and the direction in which it flows suddenly changes. The clusters collide violently, and the flow velocity increases rapidly and a strong swirling flow is generated, thereby subdividing the cluster state of the liquid.
As a result, the liquid can easily enter the narrow gap between the objects.

Such a phenomenon is sometimes called a nanobubble phenomenon and can be applied in various fields. For example, a nanobubble generator can be used for household or commercial showers to create a moisturizing effect on the skin, to make it easier to remove dirt, or as a coolant for cutting parts of machine tools or as a coolant for engine radiators. It is possible to increase the cooling effect by using it, or to increase the fuel efficiency of the engine by providing the same generator in the fuel injection part of the engine and allowing liquid fuel to pass through the generator.

The nanobubble phenomenon has already been disclosed in many patent documents (for example, Japanese Patent Application Laid-Open No. 2009-247950), and the structure for generating the nanobubble phenomenon also includes a “flip-flop phenomenon generating shaft” in the casing. A fixing structure for fixing and generating a swirling flow with respect to a passing liquid is already known (Patent Document 1).
However, the structure of the above-mentioned nanobubble generator known as a “flip-flop phenomenon generating shaft” is complicated, and when it is actually manufactured, a commercially available metal bar or plastic bar is gradually cut using a machine tool. In many cases, it is finished to a desired shape while being processed, and it takes a long time for processing, and the processing cost tends to be expensive. In fact, a commercially available shower incorporating a nanobubble generator is also expensive.

Therefore, a new structure of a nanobubble generator capable of generating the nanobubble phenomenon inexpensively and easily has been desired.

Provided is a nanobubble generator fixing structure for easily and inexpensively generating nanobubbled liquid.

The inventor of the present invention does not cut the material of the nanobubble generator, but injection-molds a plurality of individual blades A constituting the nanobubble generator, and then connects these blades A individually. Using this structure, we discovered that nanobubble generators can be manufactured quickly and easily outside of the desired structure and adopted as a means for solving problems.

Specifically, a liquid inlet and a liquid outlet are provided in the casing, and the nanobubble generator is configured by fixing the nanobubble generator on the liquid flow path ([FIG. 6]).
The nanobubble generator is formed by injection-molding a blade A consisting of a large number of protrusions, such as a sector, rhombus, hexagon, etc., with plastic, and connecting the plurality of blades onto a stacking fitting shaft. It is characterized by.

By incorporating a nanobubble generator according to the present invention into a cylindrical casing, a nanobubble effect can be obtained for a liquid that has passed through the generator.

Furthermore, the present invention adopts a structure in which a plurality of plastic-shaped blades A are connected to the laminated incorporation fitting shaft for the nanobubble generator, and is fixed inside the casing provided with a liquid inlet and a liquid outlet at both ends. As a result, a nanobubble generator having the same function as the “flip-flop phenomenon generating shaft” can be obtained easily and extremely inexpensively, and the nanobubble generator can be mass-produced at low cost.

This makes it possible to easily and inexpensively form a large amount of liquid, such as domestic water and industrial water, which can be easily produced at a low cost, and can bring about great effects in terms of water saving and cleaning.

Hereinafter, the present invention will be described with reference to FIGS.

As shown in FIG. 1 and FIG. 2, the blade A is provided with a hole 5 through which the shaft passes in the center, and the blade A is connected to another blade A in a portion adjacent to the outer peripheral portion of the hole 5. A plurality of fitting holes 6 and convex portions 7 are provided. A plurality of rhombus or fan-shaped protrusions are provided outside the fitting hole to form the blade A.

  Furthermore, you may form so that each center part of the boss | hub of the fitting hole 6 and the fitting convex part 7 may shift | deviate by a fixed angle [FIG. 8]. When the nanobubble generator 4 is formed by sequentially connecting, for example, about 10 to 20 blades A, the center portions of the bosses of the fitting hole 6 and the fitting convex portion 7 are 4.5 to 4.8 degrees. It is desirable to form the blades A so as to deviate to some extent. As described above, when a plurality of blades A formed so that the center portions of the bosses of the fitting hole 6 and the fitting convex portion 7 are deviated from each other by a certain angle, the protrusions on the outer peripheral portion are deviated by the angle between adjacent blades A. , The outer peripheral portion of the nanobubble generator formed by adjoining a plurality of blades A has a spiral shape, and further enhances the swirl flow in which the liquid passing through the generator is generated.

  The blade A having the shapes shown in [0013] to [0014] is manufactured by plastic molding.

The nanobubble generator 4 ([FIG. 6]) is configured by successively connecting, for example, about 10 to 20 blades A to a shaft for stacking and fitting that has a conical shape on the liquid inlet 2 side.

The connecting method may be any method, and the blades A may be bonded with an adhesive or may be ultrasonically welded. Further, a blade B ([FIG. 4] [FIG. 5]) from which only convex portions are removed from a blade A shaped as in [FIG. 1] to [FIG. After fitting to A, the center of the blade B may be bolted to the shaft for stacking and fitting ([Fig. 7]), or the blade B is bonded to the connected blade A with an adhesive. Or ultrasonic welding.

Note that the present invention is not limited to the above-described embodiment, and the dimensions of the blade A and the blade B change depending on the nature of the liquid passing through the nanobubble generator 4 and the difference in fluid hydraulic pressure. The number of A used also increases or decreases.

It is the perspective view which looked down at the blade | wing A which is one Embodiment of this invention from the fitting hole 6 side. It is the perspective view which looked down at the blade | wing A from the fitting convex part 7 side. 3 is a side view of a blade A. FIG. As a means for connecting a plurality of blades A, when the blades A are fitted together and bolted with a plurality of blades A from the outside of the blades A, a perspective view of the blade B inserted between the blades A and the bolts is there. FIG. 5 is a rear perspective view of FIG. It is the side view which incorporated the nano bubble generating body by this invention in the cylindrical casing 1, and was completed as a fixed structure of a nano bubble generating apparatus. It is the side view which showed the state of the shaft before connecting the blade | wing A sequentially. It is a perspective view of the state manufactured by shape | molding the blade | wing A which is one Embodiment of this invention by plastic molding.
