Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem wherein a conventional emulsification apparatus of a low quality oil merely agitates an oil with water, hence it is hardly judged whether a fixed proportion of oil and water is completely emulsified or not, therefore the mixture is hardly utilized effectively as an emulsion liquid. <P>SOLUTION: This emulsification apparatus for a low quality oil includes a water tank, an oil tank, an ozone generator and an agitation tank. The water tank and the oil tank are connected to the agitation tank each through a channel. The ozone generator is connected to the agitation tank through a channel, and by operating an agitator in the agitation tank, water and the oil are emulsified while feeding ozone. A return tank is connected to the agitation tank through a channel and a water sensor is disposed in the return tank. When this water sensor becomes no more detecting moisture, a signal is transmitted. <P>COPYRIGHT: (C)2007,JPO&INPIT

  However, in such a conventional low-quality oil emulsification apparatus, since water and oil are merely stirred, it is difficult to determine whether a certain ratio of oil and water is completely emulsified, It had the inconvenience that it was difficult to use effectively as an emulsion.

  An object of the present invention is to eliminate this inconvenience.

  In order to achieve this object, the inventors have intensively studied and completed this invention.

  The low-quality oil emulsification apparatus according to the present invention includes a water tank, an oil tank, an ozone generator, and a stirring tank, and connects the water tank and the oil tank to the stirring tank through flow paths, respectively. In the low-quality oil emulsification apparatus, the ozone generator and the stirring tank are connected via a flow path, and water and oil are emulsified while supplying ozone by operating the stirrer in the stirring tank. A return tank is connected to the agitation tank via a flow path, and the return tank is connected to the agitation tank via a flow path, and a water sensor is provided in the return tank so that the water sensor does not detect moisture. A signal is emitted when

  A separation tank may be interposed between the agitation tank and the return tank to separate moisture and other oil components (oil and emulsion), and these may be poured into the return tank via a flow path.

  Since the low-quality oil emulsification apparatus according to the present invention is configured as described above, water and oil are stirred in the stirring tank to form a mixture of the emulsion liquid, water and oil, and then the return tank is installed. Then, it is supplied again into the stirring tank. Repeat this action. When the water sensor in the return tank does not detect moisture, a signal can be transmitted to notify the completion of the emulsification of oil and water.

  Therefore, if this apparatus is used, it can be easily known that a predetermined amount of water and oil has been completely emulsified, and effective utilization of the low-quality oil emulsion liquid can be facilitated.

  In addition, if a separation tank is interposed between the stirring tank and the return tank to separate moisture and other oil components (oil and emulsion), these are poured into the return tank through a flow path. In the middle stage (at the stage where moisture remains in the emulsion liquid), the emulsion liquid not containing water can be taken out.

  The low-quality oil emulsification apparatus according to the present invention connects a return tank to the stirring tank via a flow path, connects the return tank to the stirring tank via a flow path, and a water sensor in the return tank. And when the water sensor does not detect moisture, the operation of the agitator is stopped.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a fluid system diagram of a low-quality oil emulsification apparatus according to the present invention, and FIG. 2 is a cross-sectional view thereof.

  In the figure, A is a low-quality oil emulsifying device, and has a water tank 10, an oil tank 20, and a return tank 30. The water tank 10 contains water, and the oil tank 20 contains light oil. The return tank 30 will be described later.

  Reference numeral 50 denotes a stirring tank, which has a stirrer 51. The agitation tank 50 is connected to the water tank 10 by a flow path S through an opening / closing valve 11 and a flow meter 12. Similarly, the oil tank 20 is also connected by a flow path S via an opening / closing valve 21 and a flow meter 22. The flow path S from the water tank 10 and the flow path S from the oil tank 20 merge on the downstream side of the on-off valves 11 and 21 and the flow meters 12 and 22, respectively.

  The flow meter 12 of the water tank 10 is for measuring the amount of water supplied to the stirring tank 50 based on the mixing ratio of the emulsion, and the flow meter 22 of the oil tank 20 is supplied to the stirring tank 50. This is for measuring the amount of light oil supplied based on the mixing ratio of the emulsion. These measurements are performed by opening the respective open / close valves 11, 21 and are closed after measuring a predetermined amount.

  The stirrer 51 has a rotating shaft 52. The rotating shaft 52 is rotatably installed in the stirring tank 50, and one end protrudes outside the stirring tank 50. A stirring blade 53 projects from the side surface of the rotating shaft 52. The stirring blade 53 rotates together with the rotating shaft 52 to stir and mix the water in the stirring tank 50 and the light oil. Reference numeral 521 denotes a magnet, which is installed inside the rotating shaft 52. When the magnet 521 is installed in this way, a stable emulsion of water and light oil can be obtained without ozone as described later.

  Reference numeral 54 denotes a gad motor, which is installed in the vicinity of the stirring tank 50. The gad motor 54 transmits its rotation to the rotary shaft 52 through gear mechanisms 55 and 56. Therefore, the stirrer 51 in the stirring tank 50 can be operated by operating the gad motor 54.

  An ozone generator 60 is connected to the agitation tank 50 by a flow path T through a compressor 61. Therefore, the ozone generated by the ozone generator 60 is pressurized by the compressor 61 and blown into the agitation tank 50 through the through holes 58, 58,. This ozone is for promoting stable emulsification of the water and light oil. Since a conventional emulsifier such as a surfactant is not used, when the formed emulsion liquid is used, the surfactant is not affected as in the prior art.

  The formed mixed liquid of emulsion liquid, water, and light oil flows into the separation tank 70 via the flow path S. On the way, a pressurizing pump 59 is installed, and this mixed liquid is pumped to the separation tank.

  Reference numeral 71 denotes a separation filter, which is installed in the separation tank 70. This separation filter 71 passes only the emulsion liquid and light oil in the mixed liquid (emulsion liquid, water and light oil), and separates these from water. The separated water and the mixed liquid of the emulsion liquid and the light oil flow into the return tank 30 by the two-way adjustment of the switching valve 73, respectively. A water sensor W is installed in the return tank 30 to detect the presence or absence of flowing water. When water is present, these mixed liquids (emulsion liquid, water and light oil) are supplied again into the agitation tank 50 via the flow path S and are emulsified by the agitator 51. At this time, it passes through the check valve 31 and the opening / closing valve 32. Then, the circulation with the separation tank 70 described above is repeated. When this circulation is started, the pressure of the compressor 61 is reduced and the pressure of the supplied ozone is lowered.

    When the water sensor of the return tank 30 does not detect moisture in the state where the circulation of the emulsification is repeated, the water sensor 30 is turned on to notify the completion of the emulsification. In addition, although this water sensor-30 determines the presence or absence of water | moisture content by measuring an electrical conductivity, the water sensor which exists conventionally can also be used.

    The cock 75 of the separation tank 70 is for taking out a mixed liquid (emulsion liquid and light oil) from which water has been separated.

    D is drainage of the flow path S.

    In this embodiment, “light oil” has been described as the oil, but it can be applied to other oils.

  Since the signal is transmitted when the emulsification is completed, the operator can easily know the completion of the emulsification. It can be used to promote effective use of low-quality oil emulsions.
