Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for densely and uniformly mixing liquids that are difficult to mix with each other, for example two liquids having completely different properties such as oil and water.

Conventionally, it is well known that ultrasonic vibration energy is used as a means of mixing liquids that are difficult to mix, such as oil and water. Because of the need to harness the vibrational energy of sound waves, large electrical inputs or multiple vibration systems were used.

As a result, the structure of the device becomes complicated and expensive, and the thermal stress caused by the vibration of the vibrating system causes it to break or break, resulting in a significantly shortened lifespan.

Therefore, in the present invention, even when a large volume of liquid is mixed, a vibration system is vibrated with a small electric input to mix the liquid.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a vibration amplifying horn, and one end surface of an ultrasonic vibrator 2 which is energized by an ultrasonic oscillator 4 via a conductor 3 is fixed to the other end side.

6 is a liquid supply path raised above the center axis of the vibration magnifying horn 1;
One end is the small tip surface of the vibration magnifying horn 1, that is, the atomization surface 1
', and the other end reaches a mixing volume chamber 5 formed at the center of the inner side of the large end face of the ultrasonic transducer 2, connecting the two.

One side of the mixing volume chamber 5 is formed by the radiation surface of the ultrasonic transducer 2, so that the ultrasonic transducer 2 faces the mixing volume chamber 5.

Further, a passage 7 communicating with the mixing volume chamber 5 is connected to a liquid supply pipe 8 that is connected to flow rate regulators 9 and 10 that adjust the flow rates of liquids having different properties.

Next, from an operational point of view, two liquids having different properties whose flow rates are adjusted by the flow rate regulators 9 and 10 pass through the liquid supply pipe 8 and the passage 7, and are located at the center of the large end face of the vibration magnifying horn 10. It reaches the mixing volume chamber 5 whose one side faces the tip of the ultrasonic vibrator 2, that is, the vibration radiation surface, and then passes through the liquid supply port 6 to the atomization surface 1', where a thin liquid film is formed by surface tension. , which is what is atomized here.

In this case, as an example, when a liquid that is difficult to mix such as water and oil is used, both liquids are two liquids that are temporarily stored in the mixing volume chamber 5, and the oil and water are the two liquids that are used for ultrasonic radiation. Cavitation occurs under the influence of sound pressure, and the two liquids become mixed with each other under a kind of stirring action.

In other words, the vibration radiation surface collides with the liquid, causing instantaneous mixing.

After that, the liquid passes through the liquid supply port 6 and reaches the atomizing surface 1', but the vibration form of the vibration magnifying horn 1 is such that the vibration is magnified as it goes toward the small tip side, and at the atomizing surface 1'. Since it is designed to obtain the maximum amplitude, as the two liquids previously mixed in the mixing volume chamber 5 pass through the liquid supply port 6, the mixing is further promoted.

At the atomizing surface 1', a liquid film forms and becomes fine particles that are scattered forward, but the pattern of atomization due to ultrasonic vibration depends on the vibration amplitude of the atomizing surface 1'. Depending on the selection of the ultrasonic frequency and electrical input, very uniform particles can be obtained.

That is, since the two liquids are formed in molecular form, the premixed two liquids are completely mixed in a dense state during the atomization process.

As described above, the present invention provides a mixing volume chamber facing the ultrasonic transducer, and supplies at least two types of liquid to each mixing volume chamber via a flow rate regulator. The liquid is directly vibrated by the ultrasonic vibrator and subjected to a strong mixing action, and as it passes through the liquid supply channel provided on the central axis of the vibration amplifying horn to the atomization surface side, it is further subjected to a mixing action, resulting in mixing. The result is that the different liquids are atomized in a substantially uniform state on the atomization surface.

Furthermore, the ultrasonic transducer in the mixing volume chamber is cooled by the liquid in the mixing volume chamber, making it less likely to be thermally degraded and simplifying its cooling configuration.
