Description

[0001] APPARATUS FOR CRASHING FLUID [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid collision apparatus for colliding particles contained in a fluid by colliding a high-pressure fluid into a chamber.

BACKGROUND ART [0002] A conventional fluid collision apparatus is a device for pulverizing particles in a fluid by impinging a high-pressure fluid injected from an injection nozzle into a chamber to atomize the particles.

The fine particles produced from such a fluid collision apparatus are widely used for materials in a wide range of fields such as foods, cosmetics, paints, ceramics, and electronic materials.

For example, in cosmetics, the foundation material is made into fine particles to improve the skin covering power and the absorbability of the secretions, thereby further improving the properties desired as cosmetics. Further, in ceramic materials, the mechanical strength is improved in accordance with the formation of fine particles. In addition, it is required to improve the affinity between the compositions by emulsification such as various foods including beverages, emulsions of paints and cosmetics, and uniform dispersion of the medium.

However, in the conventional fluid collision apparatus, there is a problem that the fluid collision surface in the chamber is locally worn and the durability of the chamber is deteriorated. Furthermore, when a large amount of fluid is targeted, there is a problem that the chamber needs to be replaced and the maintenance cost increases.

Hereinafter, a fluid collision apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Prior to this, terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary terms, and the inventor should appropriately interpret the concepts of the terms appropriately It should be interpreted in accordance with the meaning and concept consistent with the technical idea of the present invention based on the principle that it can be defined.

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention, and not all of the technical ideas of the present invention are described. Therefore, It should be understood that various equivalents and modifications may be present.

1, a fluid impact device according to an embodiment of the present invention includes a hopper 110 to which a high-pressure fluid F containing particles is supplied, and a hopper 110 to which the hopper 110 is mounted A supply pipe 130 connecting the hopper 110 and the chamber 120a to supply the high-pressure fluid F, and a gas supply pipe 130 connecting the chamber 120a to the chamber 120a. A spray nozzle 160 installed at an end of the supply pipe 130 to increase the speed of the high-pressure fluid F supplied to the end of the supply pipe 130, And a discharge unit 170 mounted on the lower portion of the discharge pipe 120 and discharging the fluid including the microparticles.

The chamber main body 120 is provided at one side thereof with an inclined discharge end portion 120b for slidably colliding with the inner surface of the chamber 120a with a high-pressure fluid F communicated with the discharge nozzle 160, And a discharge hole 120c communicating with the discharge portion 170 is formed on the lower side thereof.

The supply pipe 130 is formed by boring the chamber cover 150 and the chamber body 120 in a state where the chamber cover 150 is coupled to the chamber body 120, And the sealing member S is inserted into the outer portion of the waste oil path.

The fluid impingement apparatus of the present invention may further include a rigid body 140 inserted into the chamber 120a of the chamber body 120 but colliding with the high pressure fluid F ejected therefrom. In this case, the rigid body 140 may be detachable if necessary, and may be formed of any one of ceramics, cemented carbide, summit, and hardened steel to preserve the durability of the chamber body 120. In addition, the hard body 140 has a cylindrical or square pillar-shaped inner surface. Needless to say, the rigid body 140 is not an essential component of the fluid collision apparatus, and the inner surface of the chamber 120a may be formed as a cylinder or a quadrangular prism.

2, the spouting end portion 120b is formed by controlling the crushing strength of the particles in the fluid and the impact surface 141 of the hard body 140 or the chamber 120a by the flow velocity v of the fluid, Is positioned at a certain height (e) to minimize internal wear.

That is, the height (e) of the blowing end 120b can be specified by the following formula.

[Equation]

e = R? cos? (?: collision angle, R: radius)

When the fluid collides within the chamber 120a designed to have the design rule of the above formula, it can have the same performance as the following table.

[table]

Referring to the table above, each performance factor can be calculated for the collision angle (θ) and the flow velocity (v). If water is used for classification, the density (p) is 1000 Kg / m ³ , d = 120 x 10 ^-6 m, 40 ° <collision angle (θ) <90 °, 300 <flow velocity (v) <3300 m / s As shown in FIG. 3.

Referring to FIG. 3, it can be seen that the impact force F is very sensitive to the impact force F about 1600 m / s when the impact surface 141 bends perpendicularly (θ = 90 °) have. That is, when the fine particles are simply treated with only a strong impact force, they are exposed to the risk of deterioration of physical properties even with only a single impact, so that it is preferable to perform the treatment gradually over 100 to 300 times.

As described above, the fluid collision apparatus according to the present invention can be flexibly manufactured by the design rule of the above formula. In the present invention, the design is made such that the collision angle θ is 79 °, the radius R is 16.57 mm, and the height e is 3.16 mm. If the height e is changed, Can be changed to the design rule of "formula".

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. It is to be understood that various changes and modifications may be made without departing from the scope of the present invention.

An example will be described with reference to FIG. However, only the portions different from the above-described embodiment will be described so that the recesses can be clearly grasped (names are the same, and reference numerals are assigned to the 200th segment).

The fluid impact device according to another embodiment of the present invention is formed in a pair such that the supply pipe 230 is symmetrical to both sides of the chamber body 220. In this case, inter-fluid collision occurs primarily at the point C where the ejected high-pressure fluid F intersects, and subsequently, the secondary surface of the impact surface 241 of the rigid body 240 or the inner surface of the chamber 220a So that the collision between the metal and the fluid can be induced.
