Abstract

The present invention is to obtain a high dispersion effect and the highest fineness of the liquid disperser used to disperse the selected compositions in a solution to produce a mixture of the solution and the composition. More specifically, 85% of the practical volume of the dispersion container of the liquid disperser is diameter Filled with 0.2m / m ceramic beads, the center of the container is equipped with several sprocket type impellers on the drive shaft for powerful composition forced circulation and the baffle ring on the inner wall of the dispersion container. Dispersion vessels as the compositions and beads circulate between the baffle ring and the sprocket type impellers mounted on the central drive shaft by centrifugal force due to the high speed rotation of the central drive shaft (1200 rpm). The baffle ring mounted on the inner wall prevents free circulation of the bead group and the composition so that the bead group and the composition naturally The long stay inside the acid container results in a longer time and distance for the compositions to pass between the beads, resulting in a high dispersion effect and a very small particle size (average particle size of 0.17 micron), as well as maximum spacing between the sprocket wing and the baffle. Narrow the sprocket-shaped blade to the same peripheral speed (peripheral speed M / Sec = 15M / Sec) as possible within the dispersion vessel. It means that the peripheral speed of both is the same as the sprocket type impeller's movement distance is 15 meters per second (15M / Sec), and the movement of the baffle ring is necessary to obtain more excellent ultra-dispersion effect. The distance is also 15 meters per second (15M / Sec), which greatly reduces the variation in the particle size of the composition, enabling ultra-dispersion of uniform particles, and the capacity of the dispersing vessel is 4 liters (Litre). The dispersion effect reached the average particle size of 0.17 micron or less, and the hourly output was shown to be comparable to that of 30-50 liters of conventional liquid disperser and baffle ring mounted on the inner wall of the disperser. ) And a high performance fanshape disc separator, and the capacity of the dispersing vessel is greatly reduced. This greatly reduces required horsepower and is characterized in that the ratio is significantly reduced.

Description

Equipment for accelerating dispersion and Disc separator for fine particle size of liquid type materials}

The present invention is an essential technology in the chemical, food, pharmaceutical, pigment, paint, paper and cosmetic industries that require liquid dispersion and relates to a liquid disperser used to disperse selected compositions into a solution to produce a mixture of the solution and the compositions. The volume and size of the dispersing vessel of the liquid disperser were greatly reduced, and a baffle ring was installed on the inner wall of the liquid disperser to prevent the flow and circulation of the beads and compositions. The driving shaft installed in the driving shaft is equipped with a sprocket type impeller specially designed to flow the bead group and the composition strongly, thereby strengthening the circulation of the bead group and the composition and continuously repeating the movement. The sprocket blades mounted on the drive shaft allow the beads and compositions to Strong vortexing and flow, and the baffle interferes with the flow of the fluid (beads / compositions) trying to flow only in the direction of the outlet (11) while the composition and the beads are placed in a constant space between each baffle ring. By inducing to stay evenly filled with the same amount of beads and compositions in the narrow space between the baffle ring and the baffle, there is almost no dead zone. The baffle ring also controls the flow of beads and compositions and prevents the final compositions from tipping in the direction of the outlet of the bead group when they are discharged, thereby making the compositions and beads baffle ring and baffle ( Since almost the same amount always stays in a certain space between the baffle rings, the centrifugal force by the strong rotation of the sprocket type impeller blades mounted on the drive shaft increases the uniform dispersion efficiency and the ultra fine dispersion in the dispersion container. The uniform particle size distribution as well as the hourly output increase significantly. In order to satisfy the above conditions, a powerful cooling system is required, and a spiral type cooling system is applied outside the dispersion vessel of the liquid dispersion machine, and the outer surface of the driving shaft is also spiral. It is composed of) type cooling system and strong cooling effect is possible to disperse heat sensitive composition. The miniaturization of the liquid disperser is easy due to the color exchange, and it is easy to change the beads easily, to wash the dispersion container and the beads easily, to consume a small amount of the cleaning solvent, and to reduce the amount of used beads and to greatly reduce the power cost. Manufacturing cost is reduced. 1 and 2 are structural diagrams showing the structure of a general liquid disperser. As shown in FIGS. 1 and 2, the flow of beads in a dispersion container of a general vertical and horizontal liquid disperser in operation is as follows. In Figure 1, in the case of a vertical mill (Vertical mill) it can be seen that the beads are bent down due to the weight of the beads (Weight). In this case, the lower part of the dispersion vessel in which the bead is concentrated, the dispersion is well achieved, and the higher the upper, the better the dispersion. As a result, there is a problem that the horsepower of the driving motor is increased due to the overload at the lower end. Horizontal liquid disperser (Horizotal mill) of Figure 2 is to design the dispersing vessel of the liquid disperser in the horizontal shape to improve the phenomenon that the beads in the vertical liquid disperser is concentrated at the lower end and to obtain a better dispersing effect, this also inhale the composition during operation Due to the phenomenon that beads are oriented in the direction of the composition outlet (filtration device) by pressure (1 kg / cm2), dispersion is not uniform and fine, and due to the nature of many dead zones between the wing and the wing and the general liquid disperser Dispersion effect is not excellent due to the generation of dead zones, which account for more than 30% of the total volume of the dispersion vessel due to the use of large diameter beads (1.6-2.5m / m). Dyna mill / Pearl mills have large capacity of dispersion vessel, simple cylinder, large diameter of dispersion vessel and short length. Impeller also has a structure that itself is not a type that can circulate the composition and beads strongly. It is a circular disc and has four R-shaped grooves in a clockwise direction. The four ends of the disc are cut in a straight line and the blade consists of four elliptical grooves in the middle of the disc. More than 30% of the dispersing zone in the dispersing vessel of the liquid disperser is a blind spot ( Dead zone), and the disc separator is also composed of two circular discs, one stator and one rotor, and the two discs are stacked on top of each other to form a gap between the two discs. Gap) That is, one slot can be adjusted within 1.0-2.0m / m, so that the composition is filtered through only one gap, so the discharge amount of the final composition is very small, and a wide slot of 1.0m / m or more Vented to) Particle size distribution is not uniform and sub-micron particle size is impossible due to the discharge of large particles, and earthen enamel paint must pass at least 5 times to obtain 15 micron particle size, which is inefficient. The cooling effect is greatly decreased by the application of the phosphorus cooling system, and the composition itself passes through the dispersion vessel five times or more at a high temperature inside the dispersion vessel, resulting in overheating of 90 ℃ -120 ℃ due to the strong friction between the beads and the blades. Dispersion of sensitive compositions is absolutely impossible.

The present invention is a problem of the prior art as described above bead (bead) in the direction of the outlet (filtration device) direction and the large diameter and short dispersion vessels and bead (Bead) and wings that do not circulate strongly In order to solve the problems such as the shape of the field and also the dead zone in the dispersion container, which occupies more than 30%, and the filtration device lacking in performance and function, the size of the dispersion container of the liquid dispersion machine was greatly reduced. A baffle ring is fitted to impede the circulation and flow of beads and compositions so that the beads and compositions stay evenly in a constant space between the baffle ring and the baffle, thereby allowing Sprocket type wings disperse vessels with strong flow of beads and compositions in a constant space between the baffle and the baffle ring It is designed to achieve smooth friction and vortex movement of the composition and beads in the composition and to obtain ultra-dispersion effect by minimizing dead zone due to the installation of baffle rings and the use of fine beads. It is an object of the present invention to provide a fanshape disc separator composed of minute slots. In order to achieve this purpose, the present invention is equipped with a baffle ring to help the bead group and the composition of the composition spiral on the inner wall of the liquid disperser to greatly increase the strong flow and vortex of the composition and bead group It has several sprocket type impellers mounted on the drive shaft to create a strong fluidized bed, and allows the composition to pass evenly between the beads and the beads. The contact point and friction area between the beads and the beads were greatly improved, and the purpose of ultra fine dispersion was achieved by the application of the fanshape disc separator of FIG. 4 composed of 0.15m / m sized minute slots. There is a characteristic.

Figure 3 is a horizontal mill (Horizontal mill) of the present invention, the principle is that as shown in Figure 3 the flow of the bead group and compositions initially hit the right side of the protrusion 15 of the sprocket-shaped wing (4) By impinging on the left side of the protrusion 16 of the baffle 2, the compositions are moved by zigzag movement between the baffle and the sprocket-like wing as shown by the arrow shown in the Detail of "A" figure of FIG. By circulating the beads evenly and using fine beads with a diameter of 0.2m / m, the dead zone between the beads 11 and the beads in the dispersing vessel is extremely small, so that the contact point and the friction area between the beads and the beads are different. As shown in FIG. 3, a baffle ring 2, which is a composition dispersing promoting device having a predetermined interval, is mounted on the inner wall of the dispersing container 1 of the liquid disperser, which is a bead group and a bath. It serves to force the water through the dispersion zone 12 repeatedly and the momentum of the bead group 11 and the composition 13 between the baffle (2) and the sprocket-shaped wing (4) and the wings Keep it the same. This prevents beading of beads in the direction of the Fanshape disc separator 7, which is the outlet of the compositions, and leads to uniform particle size distribution and very fine dispersion of the compositions. In addition, the gap between the sprocket wing 4 and the baffle 2 is narrowed, so that the peripheral speed M / Sec = 15 M / Sec of the sprocket wing in the dispersion vessel is increased by 15 meters per second (15 M / s). Sec) and the permissible baffle Peripheral speed M / Sec = 15 / Sec is also equal to 15 meters per second (15M / Sec), resulting in a strong vortex and flow caused by the sprocket-type wing. The power greatly reduces the particle size variation of the compositions, so that the particles can be uniformly ultra-dispersed. The above-mentioned processes have the capacity of the liquid disperser significantly smaller than the existing liquid disperser, and the dispersing effect cannot be compared. The discharge rate is estimated to be comparable to that of a large liquid dispersion machine (30-50 litre). FIG. 4 is designed to be suitable for various liquid dispersers requiring ultra fine dispersion as a composition filtration device. The principle is a tungsten having excellent abrasion resistance as a circular disc, as shown in FIG. It consists of 24 slots cut in 24 equal parts from the center, and one slot width is 0.15m / m to enable the use of fine beads. It is also possible to increase the number of parts, and it is mounted on the right rear of the drive shaft in the dispersing vessel, and the shaft rotates at high speed with the shaft when it is driven, and it filters and discharges the composition. Disc) It is composed of 24 slots with a gap width of 0.15m / m on the surface, and the final compositions by centrifugal force and internal pressure (1kg / cm2) by high-speed rotation when the drive shaft rotates And that the filtration device by discharging a composition may consist of a very uniform and fine particle size distribution and the second structure obtained an excellent dispersing effect by being filtered / discharged through a fine 24 gaeteum (Slot).

As described above, the present invention greatly reduces the size of the dispersion vessel of the liquid dispersion machine, mounts a baffle ring on the inner wall of the dispersion vessel, and also has a sprocket type in a driving shaft installed in the center of the dispersion vessel. (Sprocket type impeller) It is equipped with multiple wings and the peripheral speed of the sprocket type impeller blades in the dispersing container by narrowing the distance between the sprocket type impeller and the baffle ring to the extent possible. Peripheral speed M / Sec = 15M / Sec, i.e. 15 meters per second (15M / Sec), and the peripheral speed of the possible baffle ring (Peripheral speed M / Sec = 15M / Sec) The movement distance of the ball is also equal to 15 meters (15M / Sec), which makes the bead and the compositions flowing in a constant space between the baffle and the baffle ring more powerful. By reducing the particle size variation of the composition, the particle size variation of the compositions can be greatly reduced.The uniform particle size distribution and the finer fineness (0.17 Micron) can be obtained. It is evaluated equally.
