Description

TECHNICAL FIELD [0001] The present invention relates to a high viscous fluid dispersion apparatus,

The present invention relates to a high viscosity fluid dispersion emulsifying apparatus, and more particularly to a high viscosity fluid dispersion emulsifying apparatus which is capable of charging a powder of a predetermined particle size in advance into an apparatus without contamination of the periphery thereof by suction force by rotation of the impeller, Viscosity fluid dispersing and emulsifying apparatus having improved structure so as to improve working efficiency and quality by uniformly dispersing the particles in a liquid even more finely.

Recently, the basic materials industry has been in the important process of fineness and uniformity such as dispersion and emulsification of particles ranging from foods, cosmetics, ink, paint, adhesives, coatings, fine chemicals and nano- To this end, various types of dispersing and emulsifying devices have been developed and used.

Dispersion is a state in which a solid is uniformly dispersed in a liquid or a liquid and exists in a stable state. Depending on the object, a suspension in which a solid is dispersed in a liquid and an emulsion in which a liquid and an interface are mixed are mixed Can be divided.

The mixture containing the liquid or solid dispersion medium and the liquid dispersion medium is stirred and rotated at a high speed using a rotary type stirring device and the dispersion medium is dispersed into the dispersion medium by a shear force to produce a dispersion system such as an emulsion (emulsion) or suspension A dispersing and emulsifying device is widely known.

In the production process of such a dispersion system, a surfactant is usually added to promote the dispersion of the dispersion medium in the dispersion medium or to stabilize the dispersion system. In the production process of such a dispersion system, the dispersion degree Dispersibility) is improved as the amount of the surfactant added increases, and the shearing force applied to the dispersion of the raw material mixture from the stirring device becomes better. Therefore, when the degree of dispersion is to be achieved, the shear force may be weaker as the amount of the surfactant added increases, but a stronger shearing force is required as the amount of the surfactant added is smaller. Generally, in a dispersion system, it is preferable that the content of the surfactant is small from the viewpoint of the quality thereof. When a surfactant is used in the production process of the dispersion system, the surfactant is inevitably contained in the wastewater discharged from the production process The wastewater containing a surfactant is difficult to be purified by a common wastewater treatment method such as, for example, an activated sludge process. Therefore, it is desirable to reduce the addition amount of the surfactant as much as possible in the production process of the dispersion system.

As an example of a dispersion emulsification apparatus for this purpose, International Publication No. WO 2003/103819 (International Publication, Dec. 18, 2003) discloses a stirring apparatus comprising a rotary impeller and a multi-stage screen member for preventing the generation of eddy currents, There is disclosed a dispersion apparatus such as a homogenizer in which a dispersion system is formed by dispersing a dispersion medium in a dispersion medium.

However, in such a conventional dispersion-type emulsifying apparatus, there is a problem that when the solid dispersed powder in the form of a pulverized powder is charged into a container containing the liquid dispersion medium, the powder is scattered and the periphery is contaminated. When the solid dispersion is added to the dispersion medium and then stirred There is a need for a dispersion and emulsification apparatus which can obtain a more efficient and homogeneous dispersed phase because it takes a long time to obtain a uniform dispersion by aggregation of the solid dispersion material.

In addition, when the emulsion has a high viscosity, the rotation speed of the rotor is significantly lowered and dispersion and emulsification of the dispersion material are not smooth, resulting in a long operation time, and it is difficult to obtain a high quality emulsion.

The first rotor 120 includes a plurality of spokes 121 formed in the illustrated embodiment at the same height as the rim between the hub 122 and the rim 123, 120 are each formed to be inclined at 5 to 20 degrees in a clockwise direction between the rim and the hub, and preferably at an angle of 10 degrees. If the inclination of the spokes is less than 5 degrees, the dispersion quality during dispersion and the load due to the dispersion medium become too large. If the inclination is larger than 20 degrees, the suction force is reduced.

The first stator 130 includes an annular boss 131 fixed to an outer circumferential surface of a drive shaft connected to an output shaft of a motor, a rim 132, and a plurality of spokes 133 integrally connecting the boss and the rim, The first and second rotors 120 and 132 are disposed on the inner side of the rim 132 and the spokes 133 on the lower side thereof.

The first rotor 120 is installed such that the spokes 121 thereof are spaced apart from the spokes 133 of the first stator 130 by 0.1 to 0.3 mm, The spokes 121 of the first rotor 130 pass through the spokes 133 of the first stator 130 to crush the solid-dispersed particles between the spokes 133 so that the solid dispersion is uniformly dispersed in the dispersion medium do.

The smaller the distance between the spokes 121 of the first rotor and the spokes 133 of the first stator 130 is, the larger the shearing force becomes, so that the aggregation of the solid dispersion material can be crushed and dispersed uniformly. And the fluidity of the emulsion is lowered. If the interval is larger than 0.3 mm, the fluidity of the emulsion is increased, but the aggregation of the solid dispersion material may occur.

The second rotor 220 and the stator 230 are disposed adjacent to the front side of the first rotor 120 and the stator 130 installed inside the main body 107 in order to disperse the solid dispersion material in the dispersion medium. Is provided inside the body guide portion (108).

As a result, the dispersion medium and the dispersion medium flow backward in a vortex state, and the dispersion medium is uniformly dispersed and emulsified by the second rotor.

It is preferable that the dispersing vanes 224 are formed to be inclined at a range of 25 ° to 40 ° with respect to the diameter of the boss. When inclined at an angle of less than 25 °, dispersibility becomes better but rotation resistance is increased. The larger the angle, the lower the rotational resistance but the better the dispersibility. Also, by the rotation of the second rotor 220, a suction force is generated which pushes the fluid backward so as to allow the dispersion medium and the dispersion medium to flow into the housing.

The dispersing and emulsifying apparatus of the present invention is suitable for dispersing and emulsifying emulsions having a viscosity of, for example, 1,000 to 5,000 cps, for example. To this end, the motor 160 includes the first rotor 120 and the second rotor 220 ) Is rotated at 500 rpm to 3,000 rpm to cause the dispersoid to be dispersed in the dispersion medium between the first and second rotors and the stator together with the suction of the dispersion medium and the dispersion medium and to pulverize the aggregation of the dispersion medium, .

It is difficult to obtain the required degree of dispersion of the solid dispersion material in the dispersion medium and the rotation speed higher than 3,000 rpm causes a problem in that the load of the motor load for rotating the rotors in the high viscosity emulsion is excessively large The motor rotation speed in the above-mentioned range is suitable.

Reference numeral 109, which is not shown in the drawing, is an inlet for the case of using, for example, a plurality of liquid dispersion media.

When the first rotor 120 and the second rotor 220 are rotated, the fluid flow in the housing is moved backward so that the pressure in the housing is lowered. As a result, the nano- Into the housing 101. [0035]

Particularly, by placing the dispersion liquid in the dispersion liquid storage vessel through a hose connected to the solid dispersion liquid inlet 103, the solid dispersion liquid is introduced into the housing by the pressure difference between the pressure in the housing and the atmospheric pressure in the reservoir, And quickly flows into the housing 101 without scattering.

The solid dispersion material introduced into the housing 101 through the solid dispersion type inlet 103 flows into the housing through the pipe connected to the dispersion medium storage container 170 and the dispersion medium introduced into the housing from the liquid dispersion medium inlet 104, Particularly, the agglomerated solid dispersion material consisting of nano-sized fine particles is mixed and dispersed by the shear action between the first rotor 120 and the stator 130 by the rotor 120, 220 / stator 130, It breaks down.

In the dispersion medium storage vessel 170, a dispersion medium such as water or a liquid phase emulsion for mixing and emulsifying is mixed with the solid dispersion medium and dispersed uniformly in the dispersion emulsion system. Then, . This dispersion emulsification process can be repeated several times as needed.

A nipple is provided in the solid dispersion containing inlet 103 of the housing to connect a flexible hose and the liquid dispersion medium inlet 104 is connected to a dispersion medium storage container 170, such as water, via a pipe.

During the rotation of the first rotor 120 and the second rotor, the air flow in the housing is moved backward so that the pressure in the housing is lowered, whereby the nano-sized finely pulverized dispersion medium and dispersion medium are separated from the respective storage containers, And the emulsion thus formed is discharged to the dispersion medium storage container and then introduced into the emulsification device again to be dispersed and emulsified repeatedly to disperse and emulsify to a required degree.

Particularly, the solid dispersion liquid is introduced into the dispersion-type storage container through the hose connected to the solid dispersion-type inlet 103 and the solid dispersion-type material is directly introduced into the housing by the pressure difference between the pressure in the housing and the atmospheric pressure in the storage container, And quickly flows into the housing without scattering in the workplace.

Then, the second rotor 220 disposed in the guide portion 108 in front of the housing rotates, and the dispersion medium and the dispersion medium are flowed in the vortex state radially outward by the dispersion vane 224, and the second stator 230 so as to crush the aggregation of the dispersion material and to disperse the dispersion material in the dispersion medium.

The spokes 121 of the first rotor 130 then sweep over the spokes 133 of the first stator 130 by the rotation of the first rotor 120 disposed at the rear, And further pulverized to obtain an emulsion in which the solid dispersion is more uniformly dispersed in the dispersion medium.

The thus-dispersed emulsion is discharged into the dispersion medium storage container 170 and then introduced into the emulsification apparatus through the inlet port and repeatedly subjected to a dispersion emulsification process for several times, for example, so that an emulsion having a required degree of dispersibility .

FIGS. 6 to 10 show an emulsifying apparatus according to another embodiment of the present invention, and the suction rotor 110 is provided in the guide portion 108 of the housing 101 to promote the introduction of the solid dispersion medium and the liquid dispersion medium.

The suction rotor 110 is fastened to the drive shaft 162 connected to the output shaft 161 of the motor 160 by bolts by an extension portion 115 extending rearward of the hub 111. The second stator 230 is fixed to the inside of the rear end of the guide portion 108 of the housing and the second rotor 220 is rotatably disposed inside the second stator 230.

The first stator 130 is fixed to the inside of the front end of the housing main body 106 flanged to the guide portion 108 and the first rotor 120 is rotatably disposed inside the first stator 130.

The suction rotor 110 and the first and second rotors 120 and 220 are fitted and fixed to the outer circumferential surface of the end portion of the driving shaft 162 connected to the output shaft of the motor, whereby the suction rotor 110, (120, 130) are rotated together.

The suction rotor 110 is connected to the hub 111 by four spokes 114 having the same height as the rim 116 in the illustrated embodiment and the first rotor 120 In the illustrated embodiment, six spokes 121 are formed at the same height as the rim between the hub 122 and the rim 123 and are connected.

The spokes 112 and 121 of the suction rotor 110 and the first rotor 120 are each formed to be inclined at an angle of 5 to 20 degrees in a clockwise direction between the rim and the hub and are preferably inclined at 10 degrees. If the inclination of the spoke is smaller than 5 DEG, the load during rotation becomes too large, and when it is larger than 20 DEG, the attraction force is decreased.

The first and second rotors 120 and 220 and the suction rotor 110 cooperate with each other by disposing the suction rotor 110 on the front side of the second rotor 220 according to the present invention to increase the viscosity of the emulsion with the increased suction force, In the example, the flowability of the dispersion is lowered during dispersion and emulsification by the suction force of the first and second rotors, thereby enabling smooth flow of the high viscosity emulsion, thereby enabling to obtain a high-quality high viscosity emulsion quickly.

Fig. 11 shows a structure in which the discharging rotor 220 'is further disposed adjacent to the discharging side from the rear of the first stator 130 for the dispersion emulsifying apparatus of another embodiment of Fig. The discharging rotor 220 'may have a structure having a plurality of dispersing vanes on a disc like the second rotor 220 having a plurality of dispersing vanes 224 on a disc 223 And is spaced rearwardly from the first rotor / stator 120/130 and disposed rearward adjacent the outlet.
