Description

Multi-Modular Inline Homogenizer Using Vortex {MODULAR INLINE TYPE HOMO MIXER USING VORTEX}

The present invention relates to a multi-modular inline homogeneous mixer using a vortex, and more particularly, it is easy to adjust the discharge pressure, to ensure a high discharge pressure can be easily transported to a long distance as well as high floor height. A multimodal inline homogeneous mixer using vortex.

As is well known, a mixer is a mixer or stirrer used for mixing two or more types of powders or soluble liquids, mixing two types of insoluble liquids, dispersing and dissolving solids in the liquid, dispersing from the solid surface into the liquid and contacting gas-liquid. Say.

Among these mixers, a homo mixer is used to homogeneously stir the stirred material.

Several types of homo mixers have been disclosed, such as the Centrifugal Pump Type and Toothed Gear Type, that is, the currently market-leading type.

By the way, in the case of the centrifugal pump type because it is configured to discharge agitated in the radial direction by using the centrifugal force generated by the rotation in the screen state, the discharge pressure is low, the pumping height (head) is not high, In addition, there is a disadvantage that the long distance transfer is difficult. For example, the leading manufacturers have revealed that the head lift is only 4-6 m (discharge pressure: 0.4-0.6 kgf · cm 2).

Therefore, to increase the discharge pressure is required to use a high-power motor is expensive, and also has a high power limit has been required to solve this problem.

In addition, the gear tooth type is a screw type using a kind of inclination angle, and has a disadvantage similar to that of the centrifugal pump type, so that there is a limit in increasing the discharge pressure.

Therefore, the applicant has applied for a core discharge pump using a vortex, but the patent is registered in the patent No. 0918808. By applying the concept of vortex, the discharge pressure can be significantly increased, and the discharge pressure can be easily adjusted. Therefore, even in the case of high-viscosity treated material, it was inferred that it could be transported to a high height and a long distance, and had a homogeneous stirring ability, and thus started research and development, and the present invention can be considered as part of the result.

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

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

As shown in FIG. 1, the multi-modular inline homogeneous mixer using a vortex according to the present invention includes a motor 100 as a driving source, a coupling 110 to which a rotating shaft of the motor 100 is connected, and a mixing chamber ( And a mixing chamber 122 for mixing the material introduced through the flange 120 into a homogeneous slurry.

In this case, the mixing chamber 122 is a casing in which the cylindrical member is flanged, the first supply 130 for supplying the first raw material for mixing to the flange 120 is connected through a pipe, for mixing on the other outer peripheral surface The second supplier 140 for supplying the second raw material is connected and installed through the pipe.

In addition, the circulation tube 150 is connected to the center of the front surface of the mixing chamber 122, the end of the circulation pipe 150 is extended upwardly and is arranged in the open upper portion of the second feeder 140 homogeneously. Allowing continuous mixing while circulating the mixed slurry.

On the other hand, inside the mixing chamber 122 is a module 300 including a plurality of the most important disk of the present invention shown in Figs.

The module 300 includes an impeller 302, a limiter 310, a concentrator 330, and a housing 320. The spacer S may be disposed between the impeller 302 and the limiter 310 to maintain a gap. May be interposed.

In addition, when the stirring disk 400 is further installed as described below, spacers S and S 'are interposed between the impeller 200 and the stirring disk 400, the stirring disk 400, and the limiter 310. At the end of the shaft 160 is provided an end cap (C) and a fixing bolt (B), which are configurations that are typically required to be equipped.

At this time, the impeller 302 is assembled to the shaft 160, which is a rotation shaft of the motor 100, as shown in Figure 4, the disc-shaped cover 220 is coupled to one side of the centrifugal pump disk 210 It has a structure made up of.

More specifically, as shown in Figure 5, the impeller 302 is provided with a cutting piece 232 having the same shape spaced apart from each other in the radial direction, such as a substantially Y-shaped protruding on one surface, Between the 232, the suction discharge passage (R) of a predetermined size is formed.

In addition, the top surface of the cutting piece 232 is provided with a vacuum guide groove 238 consisting of a vertical surface 234 and the inclined surface 236.

Thus, when the impeller 302 rotates counterclockwise, the fluid introduced into the center through the suction discharge flow path R is scattered to the inner wall of the housing by centrifugal force, and flows on the vertical surface 234 and the inclined surface 236. Due to the difference in flow velocity of the fluid, the vacuum phenomenon occurs in the vacuum induction groove 238 instantaneously. As a result, the surrounding fluid is attracted to the vacuum induction groove 238, causing a strong rotational flow and scattering again with collision. The fluid is sucked out and discharged repeatedly.

In particular, the suction discharge flow path (R) is to maximize the homogeneous stirring and dispersion effect by performing a function of cutting so that the agglomeration of the processed material is sucked or crashed and broken.

As such, the impeller 302 induces suction while diffusing and discharging the fluid circulated from the first and second supplies 130 and 140 in the direction of the inner wall of the housing 320.

In addition, although the module 300 may have various forms, as described above, the impeller 302, the limiter 310 spaced apart from the impeller 302, and the limiter 310 may be provided with minimal requirements. It includes a housing 320 to be inserted, and a concentrator 330 formed in the form of a plurality of divided pieces along the inner circumferential surface of the housing 320.

Thus, the concentrator 330 converges again the concentrated fluid radially scattered through the centrifugal force generated by the impeller 302, thereby discharging through the discharge hole 322 through the strong discharge pressure. Done.

When the module 300 is composed of a plurality of stages, for example, two stages, three stages, and four stages as shown in FIG. 3, the discharge pressure is further increased. It can be increased up to 2kgf · cm2 (when the speed of 24m / sec), which is about 5 times higher than the discharge pressure 0.4-0.6kgf · ㎠, and can be transported to a long distance. It can be said that the effect is huge.

In this case, the impeller 302 is also preferably embedded in the housing 320.

The limiter 310 is provided as a vortex isolator to smoothly and effectively induce vortex generation by blocking a swirl, that is, a protrusion formed when the fluid rotates.

The limiter 310 has a circular disk shape, and has a structure in which a plurality of air discharge holes 312 are formed in a radial direction toward the center.

Thus, the limiter 310 discharges the air introduced when the disks rotate inside the housing 330 to agitate the slurry, thereby preventing a sudden drop in the rotational flow rate by the air and maximizing the dispersion effect. That is, by blocking (disconnecting) the vortex of the fluid, the vortex generation is effectively induced.

At this time, the introduced air is removed through the air discharge hole (312) to eliminate the idling of the disk, and with the air discharge hole (312) to finely grind the slurry, even in the case of a somewhat high viscosity raw material Smooth and homogeneous mixing agitation is possible.

For this reason, the dispersibility is improved by that much, and the homogenization is increased.

In addition, the concentrator 330 is formed in a fan shape, and is provided inside the housing 320 where one surface except the discharge hole 322 is clogged to partially spread the rotated slurry toward the inner circumferential surface by centrifugal force, The other part acts to increase the discharge pressure by steadily repeating the diffusion and convergence that converge toward the discharge hole 322 because of the vortex.

Here, the module 300 may include an impeller 302 inserted into the housing 320, a limiter 310, and a concentrator 330 integrally formed in the housing 320, but FIG. 4 and 6 (b) it may be further provided with a stirring disk 400.

The stirring disk 400 is preferably disposed between the limiter 310 and the impeller 302 as shown in FIG. 4, and may comprise one module including the stirring disk 400.

In addition, the above-described disks are all assembled to the shaft 160, the shaft 160 is formed in a quadrangular shape so that it can rotate together, the center of the disk is preferably formed in a rectangular hole.

In addition, although the illustrated disks are drawn tightly inside the housing 320 for convenience of description, the disks are actually configured to have a smaller diameter than the housing 320 so that the slurry can be smoothly discharged. Since the diameters of the disks may vary, the detailed description is omitted here.

In addition, although not shown, it is possible to configure one module by further including additional disks to enhance the function if necessary, of course, in the present invention, the module 300 as shown in FIG.

Therefore, it should be seen that all the modules added or modified based on the module 300 are included in the scope of the present invention.

At this time, the stirring disk 400 is to enhance the automation function, it may be made of any one of the forms (a), (b) of Figure 4 or a combination thereof.

For example, in the case of (a), a rectangular hole is drilled in the plate surface of the disc, which also rotates counterclockwise.

In the case of (b), a plurality of circular rather than rectangular holes are formed in the shape as shown in (a), which also rotates counterclockwise.

As such, the homogeneous mixer according to the present invention can freely adjust the discharge pressure of the slurry according to the number of modules 300, and the power of the motor is significantly less than that of the conventional, while the discharge pressure and the discharge height are improved by 4-5 times or more. It is very suitable for long distance transport and high-rise transport, and it is expected that its utilization will be very large because homogenous mixing is possible even for high viscosity raw materials.
