Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an integrated grinding and dispersing apparatus equipped with a multi-

The present invention relates to a pulverizing and dispersing apparatus for pulverizing and dispersing a raw material into uniform fine particles having a predetermined particle size or less and more particularly to a vertical pulverizing and dispersing apparatus which does not use a mechanical seal, The present invention relates to a single-piece grinding / dispersing device in which a plurality of battles are connected to each other so that dispersion grinding can be continuously performed using a motor or a vertical grinding / dispersing device in which multiple battles are connected.

The pulverizing and dispersing apparatus for the production of a fine powder may be used for various paste manufacturing facilities and chemical raw materials such as ink, pigment, paint, cosmetics, medicines and paints, various coating agents, abrasives, ceramic or metal powders or various electronic materials PZT, dielectric, MLCC, ferrite, display material) and the like. Various forms such as a continuous wet grinding device are known in the art.

Generally, the constitution of a pulverizing / dispersing apparatus for pulverizing a raw material and processing it into fine particles having a predetermined particle size or less includes a charging port for charging the raw material, a pulverizing chamber for pulverizing the raw material, a pulverizing medium (grinding medium) A separator device which separates the pulverized beads from the finely pulverized raw material so that only the raw material is separated from the finely pulverized raw material after being supplied in the form of a rotating rotor or pin or slurry which applies kinetic energy to beads or balls, The ball mill is used as a pulverizing medium for the material to be dispersed and ground. Specifically, the ball mill is referred to as a ball mill, and a bead When it is used, it is called a bead mill, and the generic name is called a pulverizing dispersing apparatus.

Accordingly, when the pulverizing / dispersing apparatus is driven, the rotor or the pin in the pulverizing chamber is rotated, and beads (or balls) charged in the pulverizing chamber (bubble cell) start to move. When the raw material is put in the driven state, the raw material starts to be pulverized and dispersed by the kinetic energy of the beads. The pulverized and dispersed raw material is discharged through the discharge port, and the pulverized raw material is filtered by the separator, and the beads remain in the pulverizing chamber and continue to move by the pin or the rotor.

The wet grinding and dispersing device includes a basket installed in a bather cell and a rotor connected to a rotating shaft and positioned in the basket. A disk-shaped rotor inside the basket Shear forces are applied between the rotating disk (rotor) and the fluid mixed with abrasive liquid, grinding stone (medium such as steel balls, steel beads or alumina zirconia beads), processing material (raw material slurry) The grinding stone having a large hardness and specific gravity in the fluid and the material having a large particle size collide with each other, and thereby the pulverization and dispersion of the material are continuously performed. Thereafter, the medium is efficiently separated from the slurry, And only the pulverized slurry is recovered.

FIG. 1 illustrates a conventional wet pulverizing and dispersing apparatus. Referring to FIG. 1, the conventional structure is described in more detail. The raw material slurry in a raw material tank (not shown) is conveyed along a line by a pump, Is introduced into the crushing chamber (42) through a charging port (41) for charging the crushing chamber (42). The supplied raw slurry is placed in the crushing chamber 42 which is a space for crushing the raw material and the crushing medium 42 charged in the crushing chamber 42 by the rotation of the rotor 44 mounted on the rotating shaft 43 (See the numeral 52 in Fig. 2), for example, beads 52 made of ceramic grains with good wear resistance, and beads 52 being rotated by milling fins 45 rotating while the raw material is stirred and mixed , The raw material is pulverized into small-sized particles by the beads. The rotor 44 and the milling fins 45 or the impeller continue to circulate the raw slurry and the pulverized slurry is pulverized by the kinetic energy of the beads into a separator 46 installed in the upper space in the grinding chamber 42 Is discharged from the beads through the discharge port (47) to the outside of the crushing chamber (42) and transferred to a collecting tank (not shown). The center shaft 43 is configured to be rotated by the pulleys P1 and P2 connected to the driving motor M. In the pulverizing process, the raw slurry circulates to the raw material tank through the center of the rotating shaft 43 In order to circulate the slurry, the rotating shaft 43 may be formed to have an empty hollow shape. In order to cool the heat generated during the pulverization process, the cooling water is supplied to the cooling water tank The water jacket 49 through the cooling water inlet 48 and then discharged through the cooling water outlet 50 after cooling.

The rotor 44 and the milling fins 45 that apply kinetic energy by centrifugal force to the pulverizing beads 52 receive the rotational driving force of the motor M through the pulley power transmission devices P1 and P2, (The portion extending vertically to the lower end of the pulverizing chamber as the shaft of the pulley P2) (the milling pins are mounted on the cylindrical sleeve 45a in such a manner as to project in four directions and the cylindrical sleeve 45a is rotatably supported by the rotary shaft 43 The end cap 51 is fixed to the lower end of the rotary shaft 43 so as not to be pulled out of the rotary shaft 43.

On the other hand, in order to prevent contamination of the pulverized material by the incorporation of the wear component into the raw material during the pulverizing process, the beads which are the inside and the pulverizing medium of the pulverizer are generally formed of a ceramic material which is not easily worn, When the rotor 44 and the milling fins 45 are rotated, energy is transferred to the beads, which are grinding media filled in a battcell (grinding container) 42, to cause motion (beads swirling and rotating by centrifugal force) The raw material in the form of slurry supplied by using energy is pulverized and dispersed. As the beads actively move in the batt cell 42, the effect of pulverization and dispersion of the raw material becomes better as the beads move.

However, since the rotor or the disk coupled to the conventional fine particle grinding and dispersing apparatus described above is designed to rotate in one direction by one rotation axis, when the fine particles are crushed by the rotation of one rotation axis, the momentum of the bead and the material to be crushed Because of the limitations, the grinding efficiency was also limited.

Since it is difficult to produce a fine powder satisfying a uniform particle size distribution by carrying out one kind of dispersion grinding process, the first and second pulverization processes are generally separately performed in a manufacturing factory to produce a uniform particle size distribution Powder. Here, the difference between the primary pulverization process and the secondary pulverization process is the size of the ball or the bead. Since the particle size of the fine powder is determined by the size difference between the ball and the bead, A plurality of pulverizing and dispersing apparatuses equipped with other beads are installed in parallel, and each apparatus is provided with facilities such as a pump and a tank.

As an apparatus for improving this point, Korean Patent No. 10-1035347 discloses a pulverizing and dispersing apparatus having a rotor that rotates in different directions by the present inventors. As shown in FIG. 2, The crushing unit 200 is provided with a first motor 110, a second motor 120 and a crushing unit 200. The crushing unit 200 is provided with a crusher And a bead for increasing dispersion efficiency are introduced into the crusher 200. The crusher 200 is provided with a first rotating shaft 220 and a second rotating shaft 220 receiving power through the first motor 110 and the second motor 120, And the first motor 110 transmits the power to the first rotating shaft 220 through the first power transmitting means 130 and the second motor 120 transmits the power to the second power transmitting means 140 To transmit the power to the second rotary shaft 260 through the second rotary shaft 260.

 As described above, according to the present invention, two rotary shafts are coupled to the bell-cell, two rotary shafts are coupled to the bell-cell through different directions, and the rotation directions of the two rotary shafts are opposite to each other, And has rotors rotating in different directions in such a manner as to increase the momentum of the beads and the raw material so as to increase the grinding and dispersing efficiency.

However, according to the present invention described above, the present invention provides a single grinding and dispersing apparatus having two rotary shafts 220 and 260 rotating in opposite directions and a plurality of blanks 230 and 240 for accommodating the rotary shafts 220 and 260 The bearing support and mounting structure for each of the blanks 230 and 240 forming the crushing chambers of the rotating shafts 220 and 260 becomes very complicated. In particular, the rotating shafts 220 and 260 Two power transmission means 130 and 140 including a pulley and a belt are required to be provided for each of the two motors 110 and 120 for driving the motor. It still takes a lot of parts, the installation structure is very complicated, the layout of the device is bad, and the manufacturing cost of the device is high, This further improvement has been demanded.
