Description

Grinding and dispersing equipment for processing fine particles of raw materials

The present invention relates to a vertical or horizontal pulverizing and dispersing apparatus for pulverizing the raw material into fine particles of a certain particle size or less, and more particularly, a pulverizing chamber for pulverizing and dispersing the raw material using a plurality of grinding media; The present invention relates to a pulverizing and dispersing apparatus having a separate chamber equipped with a separator for separating raw materials from a pulverizing medium.

Grinding and dispersing equipment is used for manufacturing various kinds of pastes and chemical raw materials, such as inks, pigments, paints, cosmetics, pharmaceuticals and paints, various coatings, abrasives, ceramic or metal powder or various electronic materials (PZT, dielectric, MLCC, Ferrite, display material) and the like are used to finely grind or disperse, for which various forms such as a continuous wet mill are known in the art.

In general, the structure of a grinding / dispersing device for grinding raw materials into fine particles of a certain particle size or less is composed of an inlet for inputting raw materials, a grinding chamber for grinding raw materials, and beads as a grinding media staying in the grinding chamber. Separator device that separates beads, which are grinding media from finely pulverized raw materials, after being supplied in the form of a rotary rotor or pin that applies kinetic energy to beads, and allows only the raw materials to exit. It is equipped with the structure which can grind the raw material continuously.

As a result, when the grinding and dispersing device is driven, the rotor or the pin in the grinding chamber rotates, and the beads filled in the grinding chamber start to move. When the raw material is put in the driving state, the raw material begins to be crushed and dispersed by the kinetic energy of the beads. The pulverized and dispersed raw materials are discharged through the discharge port. At this time, the pulverized raw materials are filtered out, and the beads remain in the grinding chamber to continue the motion by the pin or the rotor.

As such, the wet grinding disperser generates a shear force between a fluid mixed with abrasive liquid, abrasive stone, processing materials, etc. and a rotating disk while a disk-shaped rotor in the cylinder rotates, thereby causing hardness and specific gravity in the fluid. The large abrasive stone and the large particle size collide with each other, so that the material is crushed and dispersed continuously.

FIG. 5 illustrates a typical wet grinding and dispersing apparatus known in the related art. Referring to FIG. 5, the prior art structure will be described in more detail. The raw material slurry in the raw material tank (not shown) is transported along a line by a pump to feed the raw material. Through the inlet 41 for injecting is put into the grinding chamber 42. Accordingly, the supplied raw material slurry is located in the grinding chamber 42, which is a space for grinding the raw materials, and is a grinding medium filled in the grinding chamber 42 by the rotation of the rotor 44 having the central axis 43, For example, the particles are pulverized into small particles by the beads through the action of being squeezed out by the rotating pins 45 while being stirred and mixed with the beads. The rotor 44 and the pin 45 or impeller continuously circulate the raw material slurry and the slurry pulverized by the kinetic energy of the beads is discharged from the beads through a separator 46 installed in the upper space in the grinding chamber 45. Separated and discharged to the outside of the grinding chamber 42 through the discharge port 47 is transported to a collection tank (not shown). Here, the central axis 43 is configured to be rotated by the pulleys (P1, P2) connected to the drive motor (M), the raw material slurry is circulated to the raw material tank through the center of the central axis 43 during the grinding process It is also possible to be configured to be, the rotation axis 43 for the circulation of the slurry may be formed so that the hollow hollow form, the cooling water to cool the heat generated during the grinding process in a separate cooling water tank It is configured to repeat the circulation process introduced into the water jacket 49 through the coolant inlet 48 from the chiller and discharged through the coolant outlet 50 after cooling.

However, when the beads leave the grinding chamber 42 during the operation of the conventional grinding and dispersing apparatus, and the filling amount of the beads in the grinding chamber 42 decreases, the grinding and dispersing effect drops sharply. Accordingly, the shape of the separator 46, which allows the beads to remain in the grinding chamber 42 and discharges only the pulverized raw material slurry, determines the performance of the grinding and dispersing apparatus. According to the current technology, it is known that beads having diameters of about 0.1 mm can be used in the grinding and dispersing apparatus depending on the structure of the separator used.

Various types of separators have been developed that can be used in the grinding and dispersing apparatus, and the types of separators listed below are representative.

1) A structure that adjusts the gap between the rotating disk and the fixed disk so that the raw material pulverized by the gap is passed (Gap Separator: suitable for the use of beads of 0.3 mm or more in diameter) (Fig. 4 (C), (D)). Reference),

2) A structure for mounting a screen of a dense wire mesh form (Screen Separator: beads up to 0.1 mm in diameter can be used) (see Fig. 4 (B)),

3) Slit hole Separator to pass raw material through multiple gaps

4) The structure that rotates the cylinder with a large number of wings to pass the beads, and passes only the raw material slurry (centrifugal separation Separator: to maintain a constant speed, suitable for low viscosity raw material) (see Fig. 4 (A)) .

Conventional particulate separators (separators) used to separate particulates as described above use screens (micro nets), spiral slit grooves, or small gaps between discs and cylinders. Centrifugal separation type is used to squeeze out beads using centrifugal force.

However, since the fine net is fixed to the hole through which fine particles are discharged by soldering or welding, it is difficult to replace the fine net when it is damaged, and when the fine net is clogged by the particles, there is a problem that a defect occurs in the fine net during cleaning.

In addition, the separation of the fine particles using the spiral slit groove has the advantage of high separation efficiency and long life.However, when processing a high hardness material, the slits are damaged and the fine particles are not separated smoothly. There is a disadvantage to be exchanged.

In addition, the fine particle separation method using a small gap between the disk and the cylinder has a problem that the separation performance is significantly reduced when the powder is stuck in the wear or gap of the disk. In addition, the separation methods except for the centrifugal separation are difficult to apply to the separation of ultra-fine particles having a diameter of about 0.3 mm or less, and the separator should be selected according to the conditions.

As described above, the conventional crushing and dispersing apparatus employs different separators for separating raw materials and beads in various forms. However, as shown in FIG. It has a common point that it is structured in one single space.

Accordingly, the kinetic energy of the beads to be concentrated in the raw material slurry is also transmitted to the separator 46 to impact or wear the separator parts, causing breakage, thereby causing the beads to break out, that is, external leakage. In addition, scraps of broken and worn parts are mixed with raw materials (slurry) to reduce the purity of raw materials, and mixed with crushed raw material slurry, the spilled beads cause a fatal defect in the machine, and also result in a lack of beads, which leads to a lack of Cause degradation.

In addition, the existing grinding and dispersing device is a separator 46, the rotor 44 and the pin 51 is coupled to one rotary shaft 43, and rotates at the same speed with the pin 51 and the rotor 44 at the same speed Because of this, over-pulverization may occur, and the properties of the raw material may change due to thermal energy, or reaggregation of the pulverized raw material may occur.

In order to prevent this phenomenon, if the rotating shaft 43 is rotated at a low speed, in the case of the centrifugal separator, the beads are not diffused outward due to lack of centrifugal force and are discharged to the outside together with the raw materials pushed out by extrusion, thereby reducing the grinding effect or Can damage the.

In addition, the centrifugal separator has a large discharge space (slit groove) between the wings, so the filling amount of the beads is limited in order to prevent the beads from escaping, and if it is not rotated beyond the critical speed (that is, if the centrifugal force is small), In the horizontal grinding and dispersing system in which beads are mixed with sludge raw material and leaked to the outside, the beads are filled with centrifugal separators and the external leakage of beads through the large discharge space between the initial wings of the device There is a problem that can not be used in the horizontal device as an inevitable problem.

Due to these problems and the viscosity characteristics of the raw materials, centrifugal separators that can separate and finely grind sludges of relatively high viscosity are applicable only to vertical type, and are applicable to both horizontal and vertical devices. If the sludge has a high viscosity, it will not close a small gap, so the gap cannot be smaller than a certain size.Therefore, there is a limit to the use of fine beads. Each raw material, there is a problem that there is a restriction to use to replace the type of separator in accordance with the properties of the raw material.

In addition, it is impossible to adjust the rotational speed of the rotating pin 45, which is mounted on the same rotary shaft together with the separator, causing a problem of causing over-crushing or reducing the grinding effect. It is pointed out that while the grinding efficiency increases due to the increase in the kinetic energy, the thermally sensitive raw materials can cause deformation of properties.

In addition, in the case of the conventional apparatus, when there is no movement space of beads, pulverization dispersion can not be performed, and the filling amount of beads in the grinding chamber is only up to 85% of the grinding chamber capacity, and the grinding efficiency is lowered because the apparatus is overloaded. There was.

Accordingly, the present invention has been proposed in view of the problems of the prior arts, and a pulverizing and dispersing apparatus for processing fine particles of a raw material having a structure capable of preventing over-crushing in a grinding chamber and preventing deformation of raw materials by heat. The purpose is to provide.

Another object of the present invention is to provide a raw material having a structure that can be used by mounting a variety of separator parts in accordance with the properties of the raw material supplied for grinding, such as high viscosity raw material and low viscosity raw material, and to use beads of various diameters. The present invention provides a grinding and dispersing device for processing fine particles.

Another object of the present invention is to prevent the overload on the device, and to increase the filling amount of beads in the grinding chamber to generate more kinetic energy, thereby improving the grinding speed and efficiency of the raw material of the structure for the processing The purpose is to provide a grinding and dispersing device.

Another object of the present invention is to provide a grinding and dispersing apparatus for processing the fine particles of the raw material that can be installed freely according to the characteristics of the raw material without regard to the structure of the grinding chamber, such as vertical or horizontal type have.

Grinding and dispersing apparatus for processing the fine particles of the raw material for achieving the above object of the present invention, the grinding chamber containing a grinding medium for grinding the slurry continuously supplied from the slurry raw material tank through the raw material supply pipe and ; A grinding means installed in the grinding chamber to be rotated by a rotating shaft to stir and grind the slurry and the grinding media by giving kinetic energy to the media; Motor driving means for driving the rotating shaft; A separation chamber communicating with the pulverization chamber through a connection pipe and transferring the slurry and pulverization medium pulverized in the pulverization chamber to be collected; A separator installed to be rotated by a rotating shaft in the separation chamber to filter out a grinding medium contained in the slurry, and to discharge only the slurry to the outside through the center of the rotating shaft; A motor for driving a rotating shaft equipped with the separator; It is configured to include; a return pipe is formed so that the excess slurry remaining in the separation chamber containing the grinding media without being discharged to the outside through the separator is circulated to the grinding chamber side.

According to the present invention, the return pipe is a pipe connecting the return slurry to the grinding chamber side via the raw material supply pipe, the circulation of the sludge containing the grinding medium from the separation chamber side to the raw material supply pipe side A check valve that permits only movement is provided in the middle of the return pipe.

According to the invention the separation chamber is characterized in that it is installed above the grinding chamber.

According to the present invention, the separator is any one selected from a centrifugal separator, a gap separator using a gap between a fixed and a rotating disk, a screen separator, a slot hole separator, a grid ring separator and a grid shim ring separator. It is characterized in that the interchangeable mounting on the rotating shaft.

Further, according to the present invention, the grinding chamber and the rotating shaft to which the rotor and the pin are mounted are installed vertically or horizontally.

In addition, according to the present invention, the slurry passing through the separator is characterized in that it is configured to be discharged to the outside through the hollow hollow portion of the rotating shaft.

In addition, according to the present invention, the motor for driving the grinding means and the motor for driving the separator are characterized in that the driving speed is individually controlled.

In addition, according to the present invention, the separator is characterized in that to control the size of the desired particle size through the rotational speed control.

And, the grinding and dispersing device is characterized in that it is applicable to both wet and dry.

The present invention as described above can be obtained by separately separating the grinding chamber and the separation chamber to obtain the following effects.

1) The separator rotates at high speed through the rotating shaft installed separately in the separation chamber, so the rotating shaft with the rotor and pin of the grinding chamber can be freely adjusted according to the raw material characteristics.

-. The rotation axis of the grinding chamber can be rotated at low speed to prevent over-crushing for soft dispersion, and, if necessary, can be rotated at a higher speed than the rotation axis of the separator.

-. While turning the rotary shaft of the grinding chamber at high speed has the advantage of transferring a lot of kinetic energy to the grinding media beads, thermal energy is generated in the process of grinding the raw materials, which leads to deformation of properties in the case of heat sensitive raw materials. In this case, the present invention can solve this problem by adjusting the temperature of the grinding chamber by adjusting the rotational shaft speed of the grinding chamber.

2) Separator is installed separately so that the rotation speed can be set and adjusted freely according to the situation, so that the gap separator, screen separator, slot hole separator and centrifuge Various types of components, such as separators, can be selected and mounted.

-. Since various types of parts can be interchangeably installed, they can be used according to the properties of raw materials such as high viscosity raw materials and low viscosity raw materials.

-. By replacing the separator parts, beads of diameters such as 0.03 mm in diameter that cannot be used in existing grinding and dispersing devices can be used. The smaller the diameter of the beads, the smaller the particle size of the pulverized raw material.

* 3) The filling amount of the grinding chamber beads of the existing grinding and dispersing device did not fill up to 85% of the grinding chamber capacity. The reason is that the machine can be overloaded and the grinding and dispersion cannot be done without the motion space of the beads. However, the present invention allows 100% bead filling in the grinding chamber because the beads move between the grinding chamber and the separation chamber. Accordingly, the filling amount of beads can be increased than in the prior art, thereby generating more kinetic energy, thereby increasing the grinding speed and grinding efficiency.

4) The shape of the grinding chamber can be selected according to the characteristics of the raw materials regardless of the vertical or horizontal structure.

5) Although the centrifugal separator has many advantages, it cannot be used in the horizontal structure (the grinding chamber is installed horizontally) due to the external leakage problem of beads, and the vertical structure (the grinding chamber is installed in the vertical direction). It was possible to use only in the grinding and dispersing device of the present invention. However, in the present invention, the external leakage problem of the beads disappears by applying a separate separation chamber that separates the grinding chamber and the separation chamber, so that it can be applied even in the horizontal type. This is greatly increased.

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

In Fig. 1, the grinding chamber 220 is filled with a grinding medium, for example, beads having a diameter of about 0.05 to 0.5 mm in size (which is a numerical value adjusted as necessary) (conventionally, up to 85% filling). In this state, the raw material in the tank (in the form of slurry, which contains particles to be ground) is continuously supplied into the grinding chamber 220 through the supply line 280 through a pump operation.

At the same time, when the motor 130 is driven and the rotation shaft 120 starts to rotate, the rotor 230 and the fins 240 rotate to stir and disperse the slurry and beads, thereby forming a high metal or ceramic. Beads of hardness receive fine kinetic energy by centrifugal force and start to crush into fine particles by friction with the slurry. At this time, a part of the slurry continuously pushed into the grinding chamber 220 is separated through the connection pipe 210. Since it is continuously transferred to 300, overload of the rotary shaft 120 is prevented, and since the beads move between the grinding chamber 220 and the separation chamber 300, problems in movement and grinding and dispersion of the beads are prevented. none.

The slurry pulverized in the grinding chamber 220 (including beads) is introduced into the separation chamber 300 forming a separate room through the connection pipe 210, and the rotating shaft 190 in the separation chamber 300 is The rotational speed is driven by a separate drive motor 200, and the separator 320 rotates accordingly so that the beads having a large specific gravity are pushed outwards and separated, and the slurry from which the beads are separated is subjected to the extrusion force of the pump to separate the separator. Through the narrow slit groove (gap, 430) of (320a or 320b or 320c) is forcibly discharged to the hollow portion 410 of the rotating shaft 190 (in this case, the beads are larger than the slit groove in the case of the screen type) In the case of the centrifugal type in which the discharge gap is large enough to pass through the slit groove or the beads can be pulled out, when the beads approach the separator, the beads are bounced outward by the rotating wing to be separated), the hollow part 410 By ship The slurry is being transported along the pipeline 400 recovered in the recovery tank (not shown).

On the other hand, the excess slurry remaining in the separation chamber without passing through the beads and slit grooves separated from the slurry is crushed chamber side through the return line 340 by the supply pressure of the slurry continuously introduced, or in the embodiment shown By being pushed toward the supply line 280, the circulation process, which is introduced into the grinding chamber 220 together with the slurry supplied from the raw material tank, is repeated, and the check permits flow in only one direction during the return line 340. There is a valve 340, and the slurry and beads on the raw material supply pipe 280 side do not flow back into the separation chamber 300.

rotary shaft

120, 190 is independently controlled by the motor (130, 200) Since these are respectively provided, the rotational speeds of both rotating

shafts
