Description

In the process of manufacturing paints, inks, pharmaceuticals, cosmetics, foodstuffs, batteries, electronic components, and the like, the present invention can be applied while supplying an object to be dispersed and mixing it with media that has already been put into a container. It relates to a media-type disperser for dispersing or pulverizing.

As a conventional dispersing machine, a media-type dispersing machine is known that disperses, agitates, or pulverizes an object to be dispersed using media (for example, beads of glass, zirconia, etc.). For example, a disperser equips a rotating shaft in a container with a plurality of discs for dispersing at equal intervals. The disk has a plurality of protruding pieces on its outer circumference and a through hole penetrating in the thickness direction. The through-hole obliquely penetrates the disk in the thickness direction from the upstream side to the downstream side in the same direction as the disk rotation direction. With this configuration, the conventional disperser is configured to return part of the object to be dispersed and the media flowing downstream from between the disc and the container from the downstream surface of the through-hole to the upstream surface ( See Patent Document 1).

Patent No. 6634493

However, the dispersing machine described in Patent Document 1 has the following problems. First, since the force to return the media to the upstream side surface of the disk through the through-holes of the disk is slightly stronger than the flow of the object to be dispersed passing through the through-holes, Only the media near the opening of the through hole on the side surface can be returned to the upstream surface. Therefore, the media cannot be evenly distributed in the container unless the gap between the discs is narrowed and the media are continuously returned to the upstream side. Therefore, it is conceivable to narrow the gap between the discs. If the gap between the discs is narrowed, the frictional heat generated by the continuous shearing of the object to be dispersed by adjacent disks accumulates in the narrow gap between the container and the disk, causing a problem of altering the physical properties of the object to be dispersed. In order to solve this problem, it is necessary to ensure sufficient space between the discs.

In addition, when the supply amount of the unprocessed material to be dispersed into the container per short period of time is increased in order to process a large amount of material to be dispersed at high speed, the force for pumping the material to be dispersed increases. That is, the flow of the object to be dispersed passing through the through-holes becomes stronger than the force that returns the media to the upstream side through the through-holes. Since the motion is hindered by the stagnation, the shear (shear speed) due to the speed difference between the media and the action of atomization (dispersion) of the dispersed object due to the collision between the media cannot be obtained. That is, there is a trade-off relationship between an increase in the supply amount of the object to be dispersed and the processing capacity, and there is an inconvenience that the production efficiency cannot be improved.

SUMMARY OF THE INVENTION The present invention has been made to solve such problems, and an object of the present invention is to provide a dispersing machine capable of processing a large amount of objects to be dispersed at high speed while maintaining uniform distribution of media in a container. .

The present invention provides a dispersing machine as follows.

That is, it is a media-type dispersing machine that disperses together with the media while feeding the media in the container and the object to be dispersed, which is introduced from the charging section provided on the upstream side of the container, toward the discharging section provided on the downstream side,
a plurality of truncated conical distributed rotors;
a rotating shaft to which the plurality of distributed rotors are rotatably mounted;
Each of the plurality of dispersion rotors has an end portion with a large outer diameter facing upstream, and when the dispersion rotors are connected to the rotation shaft, the dispersion rotor on the downstream side has a smaller outer diameter than the dispersion rotor on the upstream side. A dispersing machine characterized in that it is configured so that an outer diameter with a large diameter is large.

According to this configuration, the truncated cone-shaped dispersion rotor has a higher peripheral speed at the end with a larger outer diameter than at the end with a smaller outer diameter. Therefore, apart from the centrifugal force acting on the media due to the rotation of the dispersing rotor when the object to be dispersed is dispersed, there is a force returning the media dispersing around each tapered dispersing rotor to the upstream side (a component of the centrifugal force ) acts continuously. That is, the dispersing machine having the above configuration has a plurality of dispersing rotors connected to the rotating shaft, unlike the conventional dispersing machine that intermittently applies a force to the media to return the media to the upstream side only with dispersing disks arranged at regular intervals. continuously applies a force to return the media to the upstream side. As a result, even if the supply amount of the material to be dispersed into the container is increased, the force that causes the media to return upstream continues to act, so that the media are distributed substantially uniformly within the container. Therefore, the shearing (shear speed) due to the speed difference between the media and the atomization of the dispersion target due to the collision between the media are maintained, so that the dispersion efficiency is improved and the uneven distribution of the media in the discharge section can be suppressed. Therefore, the object to be dispersed after treatment can be smoothly discharged from the discharge port. In other words, the disperser enables high-speed processing of a large amount of objects to be dispersed while maintaining a uniform distribution of media.

Furthermore, since the truncated cone-shaped dispersing rotor can increase the distance in the axial direction of the rotating shaft compared to a thin disk, the gap between the container and the dispersing rotor is the smallest, and each dispersing rotor exerts a shearing action. The distance between the large diameter ends of the can be sufficiently enlarged. Therefore, since frictional heat generated by shearing does not accumulate in the container, it is possible to avoid deterioration of the physical properties of the object to be dispersed due to the influence of heat.

In the above configuration, the distributing rotor has an outer peripheral surface, and the outer peripheral surface may include a rough surface, or a plurality of grooves are formed along the outer peripheral surface to may extend in the direction of

With this configuration, the frictional resistance between the outer peripheral surface of the dispersing rotor and the object to be dispersed increases, so the stirring efficiency increases. In particular, the medium moves to the large-diameter portion of the dispersing rotor due to the interaction between the centrifugal force acting on the medium due to the rotation of the dispersing rotor and the force returning to the upstream side. That is, the media collide with the large-diameter edge of the dispersing rotor in the area where the gap is the narrowest in the container, and this collision provides kinetic energy, which facilitates collision of the media with each other. Therefore, the disperser configured as described above can efficiently agitate, pulverize, and disperse the object to be dispersed.

Further, in the above configuration, one or a plurality of dispersing disks attached alternately with the dispersing rotor on the rotating shaft,
The dispersing disk has a larger outer diameter than the end portion of the dispersing rotor having a large outer diameter, and has a plurality of protruding pieces on its outer circumference. , preferably has one or a plurality of through-holes penetrating obliquely in the same direction as the rotating direction of the dispersion disk.

According to this configuration, a portion of the media returned to the upstream side by the tapered surface of the dispersing rotor is returned to the upstream side through the through-holes of the dispersing disk, while this return force and the centrifugal force caused by the rotation of the distributing rotor Due to the synergistic effect of the force and the pressure of the object to be dispersed that has passed through the through-holes of the dispersion disk from the upstream surface to the downstream surface, the media gathers on the projecting piece on the outer periphery of the dispersion disk that is larger in diameter than the dispersion rotor. Therefore, while the object to be dispersed is being agitated by the rotation of the dispersing disk, the media collide with the projecting pieces of the dispersing disk and actively move. It is possible to efficiently obtain the effect of microparticulation.

In the above configuration, it is preferable that each of the plurality of grooves and the plurality of through holes of the distribution disk communicate with each other on the upstream side of the distribution rotor.

According to this configuration, the object to be dispersed that has passed through the through-holes of the dispersion disk flows into the grooves of the dispersion rotor, so that the rotation resistance of the dispersion rotor increases and is strongly agitated. That is, the centrifugal force is more likely to act on the object to be dispersed and the media, and the media can be collected more reliably toward the projecting piece of the dispersion disk. Note that the term “communication” means that, when viewed from the axial direction of the rotating shaft, the downstream opening of the through-hole of the dispersion disk is formed on the outer peripheral surface of the dispersion rotor in a state in which it is in contact with the upstream end surface of the dispersion rotor. means at least partially overlapping with the groove that was created.

The present invention provides a dispersing machine capable of processing objects to be dispersed at high speed while maintaining a uniform distribution of media in a container.

<First embodiment>
An embodiment of a media-type dispersing machine according to the present invention will be described in detail below with reference to the drawings. In the dispersing machine of the present embodiment, a dispersing machine (for example, a bead mill) that mixes and disperses an object to be dispersed using, for example, zirconia beads as a medium will be described. It can also be used as a pulverizer for finely crushing the target material. Beads are an example of media, and are appropriately selected according to the type of object to be dispersed, particle hardness, particle size, viscosity and specific gravity of the solvent (raw material paste) to be added, and the like.

The dispersing machine 1 is a horizontal dispersing machine, as shown in FIG. This disperser 1 comprises a container 2 , a rotating shaft 3 and a plurality of dispersing rotors 4 attached to the rotating shaft 3 .

The container 2 is a substantially closed cylindrical tank. One end face of the container 2 has a loading part 5 into which the object to be dispersed is loaded, and the other end face opposite to this end face has a discharging part 6 .

The input part 5 is configured by connecting a supply pipe 7 that communicates with the inside of the container. The supply pipe 7 is connected to an upstream side thereof, such as a pump for pumping the object to be dispersed.

The discharge section 6 is composed of a gap separator 8 and a discharge pipe 9 . The gap separator 8 separates the media contained in the treated dispersion object that has been pumped inside the container 2 and reached the most downstream, and objects other than the treated dispersion object (for example, media fragments, etc.). belongs to. That is, the gap separator 8 is composed of a rotating rotor 10 provided on the rotating shaft 3 and a fixed stator 11 surrounding the outer periphery of the rotating rotor 10 . By adjusting the gap between the rotating rotor 10 and the fixed stator 11, media and the like are prevented from passing through the gap. Note that the gap separator 8 is an example of the present embodiment, and may be any device as long as it can separate the media and the object to be dispersed. For example, it may be a screen mechanism.

The discharge pipe 9 discharges the material to be dispersed separated by the gap separator 8 to the outside of the disperser 1 . In this embodiment, it is composed of a mechanical seal 12 that rotatably supports the rotating shaft 3 and a fixed wall 13 that fixes the mechanical seal 12 .

Note that the container 2 has a jacket 14 on its outer periphery. The jacket 14 adjusts the temperature inside the container 2 by supplying and circulating a coolant, hot water, or the like in a flow path formed inside the jacket 14 .

The rotary shaft 3 is inserted through the container 2 from the discharge section side through the mechanical seal 12 and extends to the input section side. That is, the rotary shaft 3 is cantilevered on the discharge section side. Further, the rotating shaft 3 is directly or indirectly connected to a drive source such as a motor (not shown) on the base end side, and its rotation is controlled via a controller.

The dispersing rotor 4 has a truncated cone shape, as shown in FIGS. A plurality of grooves 15 are formed on the outer peripheral surface of the dispersing rotor 4 . The groove 15 extends from upstream to downstream on the outer peripheral surface. Furthermore, the grooves 15 are formed on the outer circumference of the dispersion rotor 4 at regular intervals. Each of the plurality of dispersing rotors 4 has an end portion with a large outer diameter directed upstream, and when the dispersing rotors 4 are attached to the rotating shaft 3 in series, the dispersing rotor 4 on the upstream side has a smaller outer diameter than the distributing rotor 4 on the downstream side. The large outer diameter of the dispersing rotor 4 is configured to be large. A through hole 16 for attaching to the rotary shaft 3 is provided in the center of the dispersion rotor 4 .

<Description of operation>
Next, the operation of the dispersing machine 1 having the above configuration will be described.

An object to be dispersed is started to be introduced from the supply pipe 7 into the container 2 into which the medium has been introduced in advance. As shown in FIG. 4, the object to be dispersed, which is pumped downstream by the pump, flows downstream in the space formed by the dispersing rotors 4 and the inner peripheral wall of the container 2. In the process, the plurality of dispersing rotors 4 rotate. agitated and dispersed by At this time, since each of the dispersion rotors 4 has a tapered outer periphery whose outer diameter increases toward the upstream side, the peripheral speed increases from the end with the smaller outer diameter toward the end with the larger outer diameter. Gradually get faster. In other words, apart from the centrifugal force acting on the media M due to the rotation of the dispersing rotor 4, the force (component of the centrifugal force) that returns the media M dispersed around each tapered dispersing rotor 4 to the upstream side is continuous. effectively. Therefore, while the media M move upstream against the flow of the object to be dispersed with a slight force, the majority of the media M is displaced by the inner peripheral wall of the container 2 and the outside of each of the dispersion rotors 4 due to the centrifugal force accompanying the rotation of the dispersion rotors 4 . Move to the upstream side where the diameter is the largest. In other words, the media moves to the area where the gap between the container 2 and the dispersing rotor 4 is the narrowest (hereinafter referred to as the "distribution area" as appropriate).

In the dispersion area the object to be dispersed is sheared by the large diameter edge of each rotating dispersion rotor 4 . Also, the media collide with the edge and actively move. Due to the movement of the media, the object to be dispersed is pressure-fed downstream while being subjected to shearing (shear velocity) due to the speed difference between the media and atomization due to collision between the media. The media M existing in the dispersed area continue to rotate while spreading radially from the edge side of the large diameter portion toward the inner peripheral wall of the container 2 .

The object to be dispersed, which has undergone dispersion processing by each of the dispersion rotors 4 , is discharged from the discharge pipe 9 after the media slightly contained therein is separated by the gap separator 8 .

According to the dispersing machine 1 configured as described above, a plurality of dispersing rotors 4 having a truncated cone shape are attached to the rotary shaft 3 with the end portion having a large outer diameter facing the upstream side. Media can be returned upstream. Therefore, the dispersing machine 1 distributes the media substantially uniformly in each section of each dispersing rotor 4 while suppressing the uneven distribution of the media M toward the most downstream discharge section during the dispersing process of the object to be dispersed. Only the objects to be dispersed can be efficiently discharged from the discharge unit 6 while improving the

Further, since the dispersion rotors 4 can increase the distance in the axial direction of the rotating shaft 3, the distance to the edge of each dispersion rotor 4 having a large outer diameter can be increased. Therefore, since the frictional heat generated by the shearing of the object to be dispersed by the edge of the dispersion rotor 4 during rotation does not accumulate in the container, it is possible to avoid deterioration of the physical properties of the object to be dispersed due to the influence of heat.

<Second embodiment>
This embodiment includes a plurality of dispersing disks in addition to the dispersing rotor 4 of the first embodiment. Therefore, the different configurations will be described in detail, and the same reference numerals will be given to the same configurations as in the first embodiment.

As shown in FIG. 5, the dispersing machine 1 of this embodiment includes dispersing disks 20 alternately attached to the rotating shaft 3 and the dispersing rotors 4 .

As shown in FIG. 6, the dispersing disk 20 has a larger diameter than the outer diameter end of the dispersing rotor 4 and has a plurality of projecting pieces 21 on the outer circumference.

The projecting piece 21 has a substantially trapezoidal shape extending radially outward. The projecting piece 21 of this embodiment includes a first side 21a extending obliquely in the opposite direction to the rotation direction R of the dispersion disk 20, a second side 21b extending in the circumferential direction from the first side 21a, and a second side 21b extending from the second side 21b. It is composed of a third side 21 c extending toward the center of the dispersion disk 20 . Also, the first side 21a and the second side 21b are gently curved and smoothly continuous. Moreover, as for the adjacent projecting pieces 21, the third side 21c of one projecting piece 21 and the first side 21a of the other projecting piece 21 are smoothly continuous.

Further, through-holes 22 are formed in the distribution disk 20 at positions slightly shifted from the projecting pieces 21 toward the center of the disk.

The through-holes 22 are holes mainly for passing media and dispersion objects. The through-holes 22 of the present embodiment obliquely penetrate in the same direction as the rotation direction R of the dispersion disk 20 from the upstream surface to the downstream surface of the dispersion disk 20 . Further, each of the openings of the through holes 22 on the downstream side surface of the dispersing disk 20 is in contact with the end surface of the dispersing rotor 4 having a large outer diameter, and the plurality of grooves 15 formed on the outer peripheral surface of the dispersing rotor 4 are in contact with each other. overlap with each other. That is, the plurality of grooves 15 and the plurality of through holes 22 of the distribution disk 20 are configured to communicate with each other on the upstream side of the distribution rotor 4 .

A through hole 23 is provided in the center of the dispersing disk 20 for attachment to the rotating shaft.

<Description of operation>
Next, the operation of the dispersing machine 1 having the above configuration will be described.

An object to be dispersed is started to be introduced from the supply pipe 7 into the container 2 into which the medium has been introduced in advance. The object to be dispersed, which is pumped downstream by the pump, is agitated and dispersed by the rotation of the plurality of dispersing rotors 4 and the plurality of dispersing discs 20 in the process of flowing downstream. At this time, as shown in FIG. 7 , the object to be dispersed passes through a large flow (hereinafter referred to as “main flow”) along the inner peripheral wall of the container 2 and the through holes 22 of the dispersing disk 20 . It consists of a small stream (hereinafter appropriately referred to as a "side stream") that Here, the flow velocity of the dispersed object is faster in the main stream than in the side stream.

In this embodiment, due to the cooperation of the dispersing rotor 4 and the dispersing discs 20 during the dispersing process, the area between the inner peripheral wall of the container 2 and the outer circumference of each dispersing disc 20 in the main flow (hereinafter referred to as the "dispersion area" as appropriate) ), media M are uniformly distributed.

First, since each of the dispersing rotors 4 whose outer diameter is smaller than the outer diameter of the dispersing disk 20 has a tapered outer peripheral surface in which the outer diameter increases toward the upstream side, the outer diameter Circumferential speed gradually increases toward the end with a large . At this time, the centrifugal force acting on the objects to be dispersed and the media M due to the frictional resistance with the grooves 15 during the rotation of the dispersion rotor 4 continuously acts between the adjacent dispersion disks 20 .

In addition to the centrifugal force, a force (a component of the centrifugal force) returning the media M around each tapered dispersion rotor 4 to the upstream side is continuous due to the difference in peripheral speed caused by the tapered dispersion rotors 4 . effectively. Therefore, the media M existing between the adjacent dispersing disks 20 move upstream against the side flow of the object to be dispersed passing through the through-holes 22 of the dispersing disks 20 with a slight force, while moving upstream against the rotation of the dispersing rotor 4. The accompanying centrifugal force draws most of it in rotation to the upstream distribution area where the inner peripheral wall of the container 2 and the outer diameter of each dispersing rotor 4 are the largest. Due to the movement of the media M between the adjacent dispersion disks 20, the media M continue to rotate while spreading radially from the dispersion disks 20 toward the inner peripheral wall of the container 2 in each dispersion area. That is, the media M are uniformly distributed in each distributed area.

While most of the media M move to the dispersion area, a small number of the media M pass through the through-holes 22 of the dispersion disk 20 and are returned to the upstream side.

Therefore, only the material to be dispersed flows downstream and is discharged from the discharge pipe 9 via the gap separator 8 .

According to the dispersing machine 1 configured as described above, the cooperation of the dispersing rotor 4 and the dispersing disk 20 continuously exerts a force to return the media M to the upstream side. Therefore, it is possible to continuously perform the dispersion processing of the object to be dispersed while uniformly distributing the media M in the dispersion area on the outer peripheral side of each dispersion disk 20 without disturbing the main flow. Therefore, the dispersing machine 1 distributes the media almost evenly in each section of each dispersing rotor 4 while suppressing the uneven distribution of the media M toward the discharge part during the dispersing process of the objects to be dispersed. It is possible to efficiently discharge from the discharge section 6 .

Also, since the dispersing rotor 4 is provided between the dispersing discs 20 that actively shear the object to be dispersed, the distance between the dispersing discs 20 is increased. Therefore, since the frictional heat generated by the shearing of the rotating dispersing disk 20 is efficiently dispersed, deterioration of the physical properties of the object to be dispersed due to the frictional heat can be suppressed.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various design changes are possible within the scope of the claims.

(1) In the dispersing machine 1 configured as described above, a configuration in which a stirring rotor is provided at the tip of the rotary shaft 3 may be employed.

That is, the pins 42 of the second row are positioned between the pins 42 of the first row on the tip side of the rotary shaft 3, and the positions of the pins 42 of the first row and the pins 42 of the second row do not overlap in the axial direction. It is configured.

According to this configuration, the media M, which tends to stay at the center of rotation on the upstream side, collides with the pins 42 due to the rotation of the stirring rotor 40 and is flipped off toward the main stream flowing along the inner peripheral wall of the container 2 . Therefore, all of the media M put into the container 2 can be used for distributed processing.
