Description

[Technical Field]

[0001] The present invention relates to a nano-dispersion device and a nano-dispersion method thereof, and more particularly to a nano-dispersion device and a nano-dispersion method thereof, which can efficiently disperse a dispersed phase by providing ultrasonic waves to a dispersion medium while simultaneously providing a dispersed phase, thereby enabling large-scale dispersion, shortening the time required for dispersion, and improving process efficiency. [Background technology]

[0002] With the development of nanotechnology, nanopowder can be produced by various methods, such as arc discharge method, gas evaporation method, sputtering method, and cryo-grinding method.

[0003] However, these nanoparticles tend to aggregate with each other, and therefore, they must be properly dispersed during or after the manufacturing process, which is particularly important when nanoparticles are mixed into a particular fluid, such as paint, ink, shampoo, beverage, or polish.

[0004] Therefore, one method for dispersing nanoparticles in a fluid is to use ultrasonic waves, which are classified into bath type, horn type, and focusing type.

[0005] Of these, the focusing method has the advantage of being able to obtain a more uniform dispersion effect, but has the limitation that it is difficult to disperse in a large volume due to the characteristics of the equipment, and the optimum dispersion effect may not be obtained.

[0006] A nanopowder dispersion device according to one conventional embodiment may comprise a fluid pipe through which a fluid containing nanopowder passes, a housing structure that surrounds the fluid pipe and has holes through which cooling water is injected and discharged, and an ultrasonic vibrator that generates ultrasonic waves to disperse the nanopowder.

[0007] However, such conventional nanoparticle dispersion devices are of a central focusing type and can disperse nanoparticles, but can only disperse nanoparticles in one section, which means that a considerable amount of time is required to disperse nanoparticles and they are less efficient.

[0008] Therefore, there is a need to develop a new nano-dispersion device and method that can accurately disperse nanoparticles while shortening the time required for dispersion and increasing the efficiency of the process.

[0030] The advantages and / or features of the present invention, and methods for achieving them, will become apparent from the following detailed description of the embodiments in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, and may be embodied in various forms. The present embodiments are provided to fully disclose the present invention and fully convey the scope of the invention to those skilled in the art. The present invention is defined only by the claims. The same reference numerals refer to the same elements throughout the specification.

[0031] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0032] Figure 1 is an oblique view of a nanopowder dispersion device according to one embodiment of the present invention, Figure 2 is a partially cross-sectional oblique view to explain the internal structure of the device shown in Figure 1, Figure 3 is a front view of the cross section of the device in Figure 1, and Figure 4 is a diagram to explain the process of dispersing a dispersed phase into nanoparticles that takes place within the device in Figure 1.

[0033] As shown in these figures, the nano dispersion device 100 according to one embodiment of the present invention forms a body having an inlet 112 through which the dispersion medium flows in and an outlet 113 through which the dispersion medium flows out after the dispersion process, and may include an apparatus housing 110 having a cooling water moving section 130 through which cooling water moves and a dispersed phase moving section 140 through which the dispersed phase flows, and an ultrasonic wave forming section 150 attached to the apparatus housing 110 for generating ultrasonic waves to disperse the dispersed phase in the dispersion medium as nanoparticles.

[0034] The device 100 of this embodiment may also include a dispersion concentration section 160 that is mounted within the device housing 110 and that accelerates the dispersion of the dispersed phase by the ultrasonic forming section 150 .

[0035] With this configuration, ultrasonic waves are applied to the dispersion medium while the dispersed phase is simultaneously supplied through the dispersion concentration unit 160, thereby allowing the dispersed phase to be dispersed efficiently.

[0036] To explain each component, the device housing 110 of this embodiment forms the basic frame of the device, and as shown in Figures 1 to 3, may include a cylindrical main body 111 that is formed in a hollow cylindrical shape overall, a pair of disc-shaped blocking plates 116 that block both openings opened by the cylindrical main body 111, and a fixing member 117 that connects the pair of blocking plates 116 and fixes the pair of blocking plates 116 to the cylindrical main body 111.

[0037] Here, the fixing members 117 are attached at three locations, for example, at intervals of 120 degrees, so that the pair of blocking plates 116 can be firmly joined to the cylindrical main body 111.

[0038] As shown in FIG. 1, the cylindrical body 111 may be provided with an inlet 112 through which the dispersion medium flows in and an outlet 113 through which the dispersion medium after dispersion flows out, and as shown in FIG. 2, the inlet 112 and the outlet 113 may be interconnected by an internal space of the cylindrical body 111.

[0039] That is, the dispersion medium that flows into the inlet 112 moves together in a fluid state along the movement path formed within the cylindrical body 111, and after the dispersed phase is dispersed in the dispersion medium at nanoparticle size by the ultrasonic forming section 150 and the dispersion concentration section 160 described later, the dispersion medium containing the dispersed phase can flow out to the outside through the outlet 113.

[0040] In this embodiment, the specific gravity of the dispersion medium may be different from that of the dispersed phase, and the material of the dispersion medium may be different from that of the dispersed phase, thereby allowing the dispersed phase to disperse the dispersion medium to the size of nanoparticles.

[0041] To elaborate, the inlet 112 and the outlet 113 of the cylindrical body 111 of this embodiment may have a circulation structure, which allows the dispersion medium flowing in through the inlet 112 to circulate.

[0042] Furthermore, the dispersed phase and the dispersion medium may be liquids, and the device according to the present invention may be used as a device for producing an emulsion in which one liquid is atomized and dispersed in another liquid.

[0043] Then, the dispersed phase having a different specific gravity from the dispersion medium enters the dispersion medium through the dispersion concentration unit 160 described later. At this time, ultrasonic waves are irradiated through the ultrasonic forming unit 150 at the point where the dispersion medium and the dispersed phase having different specific gravities meet, thereby enabling efficient dispersion of the dispersion medium.

[0044] Although not shown, for example, a pump may be provided on a path connected to the outlet 113, and a flow from the inlet 112 to the outlet 113 may be formed by the force provided by the pump. As described above, the structure may or may not be a circulation structure.

[0045] A cooling water moving part 130 through which cooling water flows may be provided at the center, i.e., the axial center, of the cylindrical main body 111 of the device housing 110. Although not shown, cooling water may be continuously supplied from a cooling water supply part to the cooling water moving part 130, thereby cooling the dispersion medium flowing into the cylindrical main body 111 and enabling the nanoparticle dispersion process to be carried out more efficiently.

[0046] In particular, the cooling water moving part 130 is provided at the axial center of the cylindrical body 111, and the ultrasonic wave forming part 150 is provided at a distance from the cooling water moving part 130. Through this, the ultrasonic waves provided from the ultrasonic wave forming part 150 are provided directly into the dispersion medium without passing through the cooling water moving part 130, thereby improving the dispersion efficiency of the dispersed phase.

[0047] Furthermore, the cylindrical main body 111 may be provided with a dispersed phase transfer section 140 that is provided parallel to the cooling water transfer section 130 at a position slightly spaced apart from the cooling water transfer section 130, as shown in FIGS.

[0048] A dispersed phase, such as oil, moves along the internal path of the dispersed phase transfer section 140, and through the dispersion concentration section 160 described later, the dispersed phase moved through the dispersed phase transfer section 140 may be divided into fine particles and provided to the dispersion region 110S where dispersion in the dispersion medium is taking place.

[0049] On the other hand, as shown in Figures 1 to 3, the ultrasonic forming section 150 of this embodiment is arranged in the cylindrical main body 111 of the device housing 110 so as to surround the central portion of the cooling water moving section 130, and can generate ultrasonic waves to disperse the dispersed phase passing through the dispersion region 110S between the ultrasonic forming section 150 and the dispersion concentration section 160 described later within the cylindrical main body 111 into fine particles in the dispersion medium.

[0050] In more detail, the ultrasonic wave generator 150 can convert electrical energy into ultrasonic energy in a focused manner to provide the ultrasonic energy to the nanopowder. The ultrasonic wave generator 150 of the present embodiment may be, for example, a PZT vibrator, but is not limited thereto.

[0051] 1, the ultrasonic wave forming unit 150 of this embodiment has a cylindrical shape and may be provided in the center of the cylindrical body 111. Referring to Fig. 3, the internal space of the cylindrical body 111 to which the ultrasonic wave forming unit 150 is attached has a hollow cylindrical shape as a whole, but there is a difference in the inner diameter of the cylindrical body 111 between sections 111a and 111c in which the inlet 112 and the outlet 113 are provided and section 111b in which the ultrasonic wave forming unit 150 is provided.

[0052] That is, the inner diameter of the cylindrical body 111 in sections 111a and 111c where the inlet 112 and outlet 113 are provided is smaller than the inner diameter of the cylindrical body 111 in section 111b where the ultrasonic forming unit 150 is provided, and the interconnected sections are provided at an incline, so that the dispersion medium flowing in through the inlet 112 can diffuse in the internal space of the cylindrical body 111 where the ultrasonic forming unit 150 is provided, and then the dispersion medium containing the dispersed phase that has undergone the dispersion process can pass through the internal section of the cylindrical body 111, which becomes relatively smaller, and flow out through the outlet 113.

[0053] In this manner, the ultrasonic forming unit 150 of this embodiment provides ultrasonic waves to the dispersion medium moving along the path formed within the cylindrical body 111, allowing the dispersion phase to be dispersed into nanoparticles.

[0054] However, in order to accelerate the dispersion of the dispersed phase into the dispersion medium, i.e., to enable the dispersion process from the dispersed phase into the dispersion medium to be carried out in a concentrated manner, the device of this embodiment may further include a dispersion concentration unit 160.

[0055] 2 and 3, the dispersion concentration unit 160 of this embodiment is provided so as to partially enclose the cooling water movement unit 130 within the cylindrical main body 111, and by providing the dispersed phase, for example, oil, which moves through the dispersed phase movement unit 140 in the same manner as in this configuration to the dispersion region 110S where the process of dispersing the dispersed phase in the dispersion medium is being carried out by the ultrasonic wave forming unit 150, the dispersion process in the dispersion medium can be accelerated. In other words, the dispersion process can be carried out intensively.

[0056] Referring to Figures 2 and 3, the dispersed phase transfer section 140, which is installed adjacent to the cooling water transfer section 130, penetrates the dispersion concentration section 160, thereby allowing the dispersed phase that has moved through the dispersed phase transfer section 140 to be provided to the dispersion concentration section 160.

[0057] The dispersion concentration unit 160 injects the dispersed phase received from the dispersed phase transfer unit 140 into the dispersion region through the mesh structure formed on the side, thereby facilitating the dispersion acceleration as well as the fine particle size of the dispersed phase.

[0058] In this embodiment, the dispersion concentration portion 160 may be made of a material containing pores 160h. For example, it may be made of a nano-structured mesh. Therefore, the dispersed phase moving along the dispersed phase movement portion 140 can pass through the pores 160h formed on the side of the dispersion concentration portion 160 and spread evenly throughout the dispersion region 110S.

[0059] The pores 160h provided in the dispersion concentration portion 160 may have a uniform size, for example, between 10 μm and 100 μm, which allows the dispersed phase to be dispersed evenly.

[0060] Furthermore, as mentioned above, the dispersion medium and the dispersed phase, which are liquids having different specific gravities but different types, are located in the pores 160h provided in the dispersion concentration section 160, thereby increasing the residence time, thereby enabling the dispersion of the dispersion medium by the dispersed phase to be more efficiently carried out.

[0061] However, the structure and pore size of the dispersion concentration portion 160 are not limited to this, and it goes without saying that other structures can be applied as long as they can evenly disperse the dispersed phase.

[0062] Meanwhile, the dispersion of the dispersed phase in the dispersion medium by the configuration of the device 100 described above will be roughly described below with reference to FIG.

[0063] First, the dispersion medium is introduced through the inlet 112 of the device housing 110. At this time, cooling water is supplied through the cooling water moving unit 130 in the direction of arrow A or the opposite direction to cool the introduced dispersion medium.

[0064] As the dispersion medium moves in the direction of arrow B along the internal path of the cylindrical body 111, an electric current is applied to the ultrasonic generator 150 to generate ultrasonic waves. The generated ultrasonic waves are provided in the direction of arrow C, and energy is transmitted to the dispersed phase through the dispersion medium passing through the dispersion region 110S, causing the dispersed phase to disperse in the dispersion medium.

[0065] At the same time, the dispersed phase provided through the dispersed phase transfer section 140 can be provided to the dispersion region in the direction of arrow D through the dispersion concentration section 160, thereby further accelerating the dispersion of the dispersed phase into the dispersion medium.

[0066] Meanwhile, a nano-dispersion method using the nano-dispersion device 100 according to one embodiment of the present invention will be described below with reference to FIG.

[0067] FIG. 5 is a flowchart of a nano-dispersion method of a nano-dispersion device according to one embodiment of the present invention.

[0068] As shown, the nano-dispersion method of this embodiment may include an inflow step S100 of inflowing a dispersion medium into the inlet 112 of the device housing 110, a dispersion step S200 of activating the ultrasonic forming unit 150 to generate ultrasonic waves on the movement path of the dispersion medium formed within the device housing 110 and dispersing the dispersed phase into the dispersion medium, and an outflow step S300 of outflowing the dispersion medium containing the dispersed phase dispersed by the ultrasonic forming unit 150 from the outlet 113 of the device housing 110.

[0069] Here, in the dispersion step S200, the dispersed phase transferred through the dispersed phase transfer unit 140 is provided to the dispersion medium through the dispersion concentration unit 160, and the dispersion of the dispersed phase into the dispersion medium by the ultrasonic forming unit 150 can be accelerated.

[0070] In the present embodiment, in the inflow step S100, cooling water is supplied through the cooling water moving unit 130, so that the dispersion medium dispersed within the device housing 110 in the dispersion step can be cooled.

[0071] As described above, according to this embodiment, ultrasonic waves are applied to the dispersion medium through the ultrasonic wave forming unit 150 while the dispersed phase is simultaneously applied through the dispersed phase transfer unit 140, thereby enabling efficient dispersion of the dispersed phase in the dispersion medium, thereby shortening the time required for dispersion and improving process efficiency. Furthermore, this configuration makes it possible to disperse the dispersed phase in a large volume of dispersion medium, enabling the capacity of the device to be increased.

[0072] While specific embodiments of the present invention have been described above, it goes without saying that various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the following claims and their equivalents.

[0073] Although the present invention has been described above with reference to limited embodiments and drawings, the present invention is not limited to the above embodiments, and various modifications and variations can be made by those skilled in the art based on such descriptions. Therefore, the spirit of the present invention should be understood only by the scope of the claims set forth below, and all equivalent or similar modifications are also within the spirit of the present invention.
