The present invention relates to a stirrer for stirring a mixture (bunker oil + water) according to the production of emulsified fuel oil, and more specifically, the vortex phenomenon of the impeller provided in the cone-shaped stirring tank and The present invention relates to an agitator for producing an emulsified fuel oil, which can greatly improve the stirring performance through the activity of the mixture by ultrasonic vibration.

Emulsion fuel oil (emulsion fuel oil) is prepared through the process of mixing water in a suitable proportion of water to the bunker oil, which is a waste fuel resource, by adding an appropriate amount of an emulsifier additive to agitate and emulsify so that oil and water separation does not occur.

In particular, in the process of manufacturing the emulsified fuel oil, the most important thing is, first of all the work to stir through the stirrer while adding the emulsifying additive so that oil and water separation of the bunker oil and water constituting the mixture does not occur.

Therefore, although the stirrers for stirring the mixture according to the manufacture of the emulsified fuel oil are conventionally manufactured to have various structures, in the case of the stirrers used in the prior art, a structural problem occurs that the stirring efficiency is significantly lowered. Here is an example:

 Looking at the structure of a conventional stirrer, the stirrer used for the production of refined oil using waste oil, the production of alternative fuel oil, etc., the inner circumferential surface of the stirring tank is composed of a columnar shape of the same diameter up and down, Impeller equipped with a stirring blade is a configuration installed rotatably mandrel.

In the case of such a conventional stirrer, the inner diameter of the stirring vessel is the same up and down, and since the stirring is performed only depending on the stirring blades of the mandrel impeller, the stirring time naturally takes a lot of time. For example, since the flow direction of the stirring object (fluid) accommodated in the stirring tank during the rotation of the impeller and the rotation direction of the stirring blade act in the same way, the mixing of the stirring liquid is made only by the centrifugal force and friction of the stirring object by the stirring blade. It is an inefficient structure that the agitation efficiency is inevitably deteriorated.

In addition, there is a manufacturing problem that requires a plurality of impellers, if necessary, in order to prevent excessive operation costs due to the delay of the stirring time, thereby preventing a decrease in the stirring efficiency as well as the production delay of the rapid mixture.

Therefore, the present invention was devised in view of the above-mentioned general problems, and an object of the present invention is to form a conical shape of the internal structure of the agitator tank, and to provide a spiral rotation control piece so that the natural vortex of the agitator when the impeller rotates is rotated. As a result of the stable stirring of the mixture through a swirling stream, the stirring mixture is more finely broken and agitated by the ultrasonic vibration generated by the ultrasonic vibrator provided in the stirring vessel, and thus the stirring efficiency of the mixture is increased through the stirring activity. It is to provide an agitator for producing an emulsified fuel oil having an improved structure to be improved.

In order to achieve the object of the present invention, the stirrer for producing an emulsified fuel oil comprises a stirrer for stirring a mixture (water + bunker oil + emulsifier additive) according to the production of emulsified fuel oil: the stirrer, the mixture is accommodated A stirring tank made of a conical inner circumferential surface; A spiral rotation control piece installed on an inner circumferential surface of the stirring vessel to control a rotation flow of the mixture; An impeller installed on an inner circumferential surface of the stirring tank and provided with a plurality of stirring wings; Drive means for rotating the impeller; And an ultrasonic vibrator provided on the wall surface of the stirring vessel to generate ultrasonic waves for the mixture to be stirred in the stirring vessel to activate the mixing.

According to the present invention, it is preferable that the ultrasonic vibrator is configured to generate ultrasonic waves at various angles by being disposed on a proper element of the stirring vessel.

According to the present invention, it is preferable that the ultrasonic vibrator comprises a metal vibrating body, a piezoelectric body and a fixture fixedly detachably mounted and fixed to a wall surface of a stirring tank by a screw coupling method or the like by integrally accommodating the metal vibrating body and the piezoelectric body. .

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention in detail as follows.

1 is a side view for explaining a schematic structure of a stirrer according to the present invention.

As shown therein, the stirrer 1 according to the present invention includes a stirring tank 10 in which a mixture according to the production of emulsified fuel oil, for example, waste fuel bunkerish oil, water, and an emulsifying additive is received and stirred. The bunker oil constituting the mixture may be another alternative raw material.

The stirring vessel 10 is in the form of a cone that narrows from the top to the bottom, and the inlet 12 and the outlet 14 for the injection and discharge of the stirring material is provided up and down.

In addition, the inner circumferential surface of the stirring vessel 10 having a conical shape is provided with a spiral rotating control piece 20 for forcibly suppressing the rotating flow of the stirring substance while colliding with the stirring substance.

The spiral rotation control piece 20 is preferably formed to be disposed on the inner circumferential surface of the stirring vessel 10 as a whole, and can be designed in various forms, such as arranged in a plurality of rows or crossing shapes.

In addition, the helical rotation control piece 20 may be integrally bent to the inner circumferential surface of the stirring vessel 10, or may be assembled to be disassembled and assembled.

In the inside of the stirring vessel 10, an impeller 30 for stirring the mixture is rotatably provided on the rotating shaft 32. In the titration element of the rotating shaft 32 is arranged a plurality of stirring blades 34 for stable stirring of the mixture.

Here, the stirring blade 34 of the impeller 30 is different from the conical stirring tank 10, and is configured to have the same circumferential diameter as a whole with respect to the rotating shaft 32, but it is most preferable to vary the vertical rotation speed of the mixture, but if necessary Therefore, of course, it may have a circumferential diameter that narrows to the same inclination angle as the inner peripheral surface of the stirring vessel (10).

In addition, a driving means 40 for rotating the impeller 30 is provided at the upper portion of the stirring vessel 10. The drive means 40 includes a motor 42 mounted on the frame 41 and a belt 44 for transmitting the power generated from the motor 42 to the rotary shaft 32.

Here, the motor 42 may include a motor capable of forward and reverse rotation.

According to the present invention, it is preferable that the impeller 30 by the motor 42 is designed to stir the mixture while rotating at about 300 to 600 RPM.

The stirring vessel 10 is equipped with an ultrasonic vibrator 50 for activating the mixture to be crushed finely to enable easy mixing. The ultrasonic vibrator 50 is preferably arranged on the appropriate element of the stirring vessel 10 having a conical shape so that the ultrasonic wave is generated at various angles.

The ultrasonic vibrator 50 is a structure in which high frequency power is converted into mechanical vibration, and transmitted to the medium through a vibrating body that transmits and amplifies the mechanical vibration. For example, as electrical energy is converted into vibration energy by a vibrating body, minute and numerous cavitations occur and disappear tens of thousands of times every second. Ultrasonic waves transmitted to the medium may be generated in various ways such as 28 Hz, 45 Hz, 100 Hz, and multiple frequencies. An example of such a frequency oscillation is shown in FIG.

The state of stirring the mixture (water + bunker oil + emulsifier additive) according to the emulsion fuel oil production using the stirrer 1 of the present invention configured as described above will be described.

When the stirring water is put into the stirring tank 10 and the motor 42 is driven to rotate the impeller 30 at a predetermined speed, the mixture is forcibly centrifugally rotated by the stirring blade 34 installed on the rotating shaft 32. , The rotating stirring is forcibly rubbed against the spiral rotating control piece 20 formed as the inner circumferential surface of the stirring vessel 10, and the rotation is prevented.

Therefore, the stirring speed of the upper and lower portions of the mixture in the stirring tank 10 is changed by the stirring blades 34 of the impeller 30 in which the stirring tank 10 has the same circumferential diameter as a cone. 10) Forced collision with the helical rotational control piece 20 provided on the inner circumferential surface of the upper and lower sides naturally freely and at the same time generates a swirling stream through the forced friction, and the occurrence of this swirling phenomenon Through this, the stirring is naturally faster and even mixing is possible.

In addition, the mixture in the stirring vessel 10 is stirred evenly by the stirring blade 34 and at the same time is activated to mix well by the ultrasonic waves generated from the plurality of ultrasonic generators 50 provided in the stirring vessel 10. For example, as illustrated in FIG. 4, the mixture to be agitated in the stirring vessel 10 by ultrasonic waves transmitted at various angles may be broken more finely, thereby enabling activation according to mixing.

According to the present invention as described above, the stirring vessel is formed in a conical shape, and also provided with a helical rotation control piece as its inner peripheral surface, so as to vary the rotational speed up and down during stirring of the mixture by the impeller and at the same time the spiral rotation control piece Due to the vortex phenomena through the forced friction due to the rapid and accurate mixing of the stirring material is provided at the same time it is provided with the effect that the mixing activity of the mixture is made easier by the ultrasonic waves generated in the ultrasonic vibrator.
