Description

  The present invention relates to a three-dimensional ball mill that rotates three-dimensionally.

  Until now, there has been no three-dimensional ball mill that rotates three-dimensionally. As a ball mill having a single mill pot, for example, there is a ball mill disclosed in Patent Document 1 (hereinafter referred to as “conventional ball mill”). The conventional mill pot has a cylindrical shape and is installed in parallel and horizontally on a pair of rollers. The rotation of both rollers is configured to rotate the cylindrical mill pot two-dimensionally in the circumferential direction. On the other hand, the inner surfaces of both end faces of the mill pot are bulged inwardly of the mill pot. This is to complicate the movement of the internal ball during rotation of the mill pot so as to efficiently perform pulverization (see Patent Document 1).

  On the other hand, Patent Literature 2 discloses a clino stud provided with a three-dimensional rotation mechanism. In the first place, the ball mill rotates at random at a low speed of 10 rpm or less in order to create a pseudo weightless state, and the purpose, configuration and operational effect of the ball mill are completely different from those of a ball mill that does not include a mill pot. For this reason, it is needless to mention as a prior art, but the three-dimensional rotation mechanism has a slight similarity to that of the present invention, so it will be described just in case.

Japanese Patent Laying-Open No. 2007-196117 (see paragraphs 0014 and 0025, FIG. 1) JP 2008-273276 A (see paragraphs 0011 and 0012, FIGS. 1 and 2)

  However, since the rotation of the mill pot is only in the circumferential direction, the ball receiving the centrifugal force by the rotation moves toward the cylindrical inner wall above the mill pot. For this reason, there are not necessarily many opportunities to collide with the said bulging part. For this reason, there are few opportunities for the ball which received the effect to contribute to crushing. Therefore, a sufficient milling effect cannot be obtained with a cylindrical mill pot that rotates two-dimensionally. The problem to be solved by the present invention is to provide a three-dimensional ball mill capable of improving this point and obtaining a sufficient grinding effect.

  In order to solve the above-described problems, the present invention has the following configurations. It should be noted that the definitions of terms used to describe the invention described in any claim are applicable to the invention described in other claims as far as possible regardless of the description order.

(Characteristics of the invention of claim 1)
A three-dimensional ball mill according to the first aspect of the present invention (hereinafter referred to as “the mill of the first aspect” as appropriate) rotates around a first axis centered on the first axis and the first axis. A first rotating body attached to the first shaft and a second shaft centered on a second axis attached to the first rotating body and extending in a direction different from the direction of the first axis. A second rotating body attached to the second shaft so as to rotate about the first axis, a mill pot that rotates integrally with the second rotating body, the first rotating body, and the second rotating body. And a driving device for rotating the rotating body. In addition, although it is common to make a 1st rotating shaft and a 2nd rotating shaft orthogonal, it does not stick to this.

  According to the mill of the first aspect, the first rotating body rotates around the first axis that is the center of the first axis. The second rotating body rotates around the second axis that is the center of the second axis attached to the first rotating body. The driving source of these rotations is a driving device. Here, paying attention to the mill pot that rotates integrally with the second rotating body, the mill pot also rotates around the first axis while rotating around the second axis. That is, it rotates three-dimensionally. By the three-dimensional rotation, the mill pot contents repeat a complicated movement compared to the two-dimensional rotation, so that more efficient stirring and crushing (crushing) is realized.

(Characteristics of the invention described in claim 2)
The ball mill according to the invention of claim 2 (hereinafter referred to as “the mill of claim 2” as appropriate) is the mill of claim 1, wherein the inner wall surface of the mill pot has a substantially spherical space surrounding it. Is formed.

  According to the mill of the second aspect, in addition to the operational effect of the mill of the first aspect, by forming the inner wall surface of the mill pot as described above, the crushed material can be smoothly run up. That is, the object to be crushed that receives the centrifugal force rises along the inner wall surface against gravity, but the inner wall surface can be used evenly and effectively by smoothing the rise. As a result, the grinding efficiency can be increased.

(Characteristics of Claim 3)
The ball mill according to the invention described in claim 3 (hereinafter, appropriately referred to as “mill of claim 3”) is configured as follows on the premise of the configuration of the mill of claim 2. That is, a part of the inner wall surface of the mill pot is formed on a curved surface or a flat surface having a smaller curvature than the curvature of the inner wall surface.

  According to the mill of claim 3, in addition to the effects of the mill of claim 2, the object to be crushed is kicked away in a direction away from the curved surface or plane by the curved surface or plane related to a part of the inner wall surface. Changes the direction of movement of the material to be crushed. Due to the change in the direction of motion, the pulverization effect of the object to be crushed can be improved compared to the case where there is no change.

(Feature of the invention of claim 4)
The ball mill according to the invention described in claim 4 (hereinafter, appropriately referred to as “mill of claim 4”) is configured as follows on the premise of the configuration of any one of claims 1 to 3. In other words, the mill pot includes an inner pot that accommodates the object to be crushed and an outer pot that protects and surrounds the inner pot. The inner pot and the outer pot may be made of different materials or the same material.

  According to the mill of the fourth aspect, in addition to the operational effects of the mill of any one of the first to third aspects, the safety of the inner pot and thus the entire mill pot can be further enhanced by the protective surrounding of the outer pot. In the first place, it is unthinkable that the mill pot itself will be damaged, but it is a safety measure that takes into consideration. Furthermore, it also has the meaning of protecting the inner pot itself from external forces.

(Feature of the invention of claim 5)
In a ball mill according to the invention described in claim 5 (hereinafter referred to as “mill of claim 5” as appropriate), the inner pot is made of zirconia on the premise of the configuration of the mill of claim 4.

  According to the mill of claim 5, in addition to the action and effect of the mill of claim 4, contamination of the inner pot can be prevented by using zirconia.

(Characteristics of the invention described in claim 6)
A ball mill according to a sixth aspect of the present invention (hereinafter, appropriately referred to as a “mill of the sixth aspect”) is based on the configuration of any one of the first to fifth aspects. A driving source that rotates the driving source, and a driving force transmission device that rotates the second rotating body around the second axis by the rotating force of the first rotating body.

  According to the mill of the sixth aspect, in addition to the function and effect of the mill of any one of the first to fifth aspects, the driving source rotates the first rotating body, and the rotation of the first rotating body is performed via the driving force transmission device. The second rotating body is rotated. That is, according to the above configuration, the entire mill can be driven by one drive source. If there is only one drive source, no complicated control is required.

(Feature of the invention of claim 7)
According to a seventh aspect of the present invention, the ball mill according to the seventh aspect of the present invention (hereinafter, appropriately referred to as “the seventh aspect of the mill”) is based on the configuration of the sixth aspect of the mill. And a driven disk fixed coaxially and a driven disk fixed coaxially to the second axis so as not to rotate. The second axis has an axis perpendicular to the axis of the first axis. It is arranged in such a manner that the peripheral edge of the driven disk is pressed against (pressed on) the plate surface of the driven disk.

  According to the mill of claim 7, in addition to the function and effect of the mill of claim 6, the function and effect of the driving force transmission device are as follows. That is, the main disk rotates integrally with the first shaft. The rotation of the driven disk due to the integral rotation is transmitted to the plate surface of the driven disk whose peripheral edge is press-contacted, thereby rotating the driven disk. The rotation of the driven disk rotates the second shaft, and the second rotating body (mill pot) is rotated by the rotation of the second shaft. Although not intended to prevent the driving source for the second rotating shaft from being provided separately from the driving device for the first rotating shaft, three-dimensional rotation can be performed by a single driving device by forming the above-described main driven relationship. Therefore, it can be very simple structurally.

(Characteristics of the invention described in claim 8)
The ball mill according to the invention described in claim 8 (hereinafter, appropriately referred to as “mill of claim 8”) is configured as follows on the premise of the structure of claim 7. That is, the pressure contact between the driven disk and the driven disk is provided on either the peripheral edge of the driven disk or the driven disk plate surface, or both the peripheral edge of the driven disk and the driven disk plate surface. It is configured so as to be performed via the elastic body (elastomer material).

  According to the mill of claim 8, in addition to the function and effect of the mill of claim 7, the following function and effect are produced. In other words, compared with the case where the pressure contact of the peripheral edge of the main disk with the driven disk surface is not performed through the elastic body, the pressure contact force and the frictional force increase due to the elastic deformation of the elastic body. Loss of transmission is reduced. That is, it is transmitted efficiently. The elastic body may be provided only on the peripheral edge of the main disk or only on the surface of the driven disk, or may be provided on both of them. Needless to say.

(Feature of the invention of claim 9)
The ball mill according to the ninth aspect of the invention (hereinafter referred to as “the mill of the ninth aspect” as appropriate) is configured as follows on the premise of the configuration of the mill according to any one of the first to fifth aspects. That is, the drive device includes a first drive source that rotates the first rotator and a second drive source that rotates the second rotator.

  According to the mill of the ninth aspect, in addition to the function and effect of the mill of any one of the first to fifth aspects, the drive source is made separate so that the first rotary body and the second rotary body can be individually driven. become. Although the control is more complicated than a single drive source, variations (for example, changing the rotational speed of one and the other) can be added to the rotation of the first rotating body and the second rotating body by individually driving. . The rotation variation enables mill pulverization according to the properties of the object to be crushed (hard and soft) and the pulverized state (coarse and fine pulverization).

  According to the present invention, the pulverization effect can be improved as compared with a cylindrical mill pot that rotates two-dimensionally.

It is a right view of the ball mill shown in FIG. In the ball mill shown in FIG. 1, it is a front view which takes out and shows a 1st rotary body, a 2nd rotary body, and a mill pot. It is a figure which shows the relationship between a main disk and a driven disk. It is the front view which used the modification of the drive device for the ball mill shown in FIG. It is a figure which shows the modification of a mill pot.

  A mode for carrying out the present invention (hereinafter, referred to as “the present embodiment” as appropriate) will be described with reference to FIGS. 1 and 3.

(Schematic structure of ball mill)
This will be described with reference to FIGS. The ball mill 1 according to the present embodiment connects a rectangular parallelepiped base portion 51 installed on a floor surface, two support columns 53 and 55 standing on the base portion 51, and top portions of the support columns 53 and 55. An outer appearance is formed by the transfer plate 57 to be used. Further, the ball mill 1 includes a first shaft 3, a second shaft 9, a first rotating body 5, a second rotating body 11 provided inside the first rotating body 5, and a driving device 7 (for example, an electric motor). ) As a main part. Here, in FIG. 2, the base 51 and the support column 55 are indicated by solid lines, and in FIG. 3, these are indicated by two-dot chain lines in order to show the internal structure.

(Shaft structure)
The reference drawings are FIGS. The first shaft 3 of the present embodiment extends in the horizontal direction around the first shaft core 3L. The first shaft 3 includes a fixed shaft 3a fixed to the support column 53 and a rotation shaft 3b fixed to the support column 55 so as to be rotatable. In this specification, when the whole axis | shaft is shown, it represents as the 1st axis | shaft 3, and when showing an axis | shaft separately, it will describe as the fixed axis | shaft 3a or the rotating shaft 3b (the 2nd axis | shaft 9 is the same). On the other hand, the second shaft 9 of the present embodiment extends in the vertical direction with the second axial core 9L as the center. The 2nd axis | shaft 9 is comprised by a pair of rotating shaft 9a and the rotating shaft 9b. The rotating shafts 9a and 9b are fixed to the first rotating body 5 so as to be rotatable as will be described later. In addition, although the 1st axis | shaft 3 and the 2nd axis | shaft 9 of this embodiment are mutually orthogonally crossed, it does not prevent making this cross | intersect at a different angle.

(Structure of rotating body)
As shown in FIGS. 1 to 4, the first rotating body 5 is a rectangular frame body, which is attached to the first shaft 3 (fixed shaft 3 a and rotating shaft 3 b), and around the axis 3 </ b> L of the first shaft 3. Is configured to rotate. The mounting position of the first shaft 3 is approximately the center in the longitudinal direction of the first rotating body 5. The reason for selecting the rectangle is only that because it is convenient in relation to the driving force transmission device 21 described later. For example, there is no problem in selecting a circular shape or other shapes. One of the first rotating bodies 5 is supported so as to be rotatable with respect to the fixed shaft 3a via a bearing 5a. The other of the first rotating body 5 is fixed to one end side of the rotating shaft 3b so as to rotate integrally. The rotating shaft 3b is rotatably supported with respect to the support column 55 via the bearing 5b, and the other end protrudes outside the support column 55. As described above, the first rotating body 5 can be rotated around the axis 3 </ b> L of the first shaft 3. Here, FIG. 4 omits the base 51, the support columns 53 and 55, the transfer plate 57, and the like shown in FIG. 1, and shows the first rotating body, the second rotating body, and the mill pot.

  A bearing 11a and a bearing 11b are provided in the center of the first rotating body 5 in the lateral direction. The rotating shaft 9a and the rotating shaft 9b are supported by the first rotating body 5 so as to be rotatable via the bearing 11a and the bearing 11b. The rotating shaft 9a and the rotating shaft 9b protrude toward the inner side of the first rotating body 5, and the protruding ends of the protrusions are fixed to the second rotating body 11 so as not to rotate. As described above, the second rotating body 11 can be rotated with respect to the first rotating body around the axis 9 </ b> L of the second shaft 9.

  The other end of the rotating shaft 3b protruding from the support column 55 is belted between the shaft of the motor (driving device) 7 and the rotating shaft 3b and the first rotating body 5 are pivoted by the rotational force of the motor 7. It is designed to rotate around 3L.

  The second rotating body 11 has a basic structure of a rectangular frame 11c having a size capable of rotating in the space partitioned by the first rotating body 5. The second rotating body 11 further includes two support plates 11d and 11d fixed with screws so that both sides of the frame 11c can be easily sandwiched and removed. Each support plate 11d, 11d is formed with a circular support hole 11h, 11h penetrating in the center. The support hole 11h is formed smaller than the diameter of the mill pot 31 to be supported, and rubber ring packings 11p and 11p are fitted around the periphery thereof. As described above, the second rotating body 11 is supported by the first rotating body 5 so as to be rotatable by the rotating shaft 9a and the rotating shaft 9b. The drive source for the second rotating body 11 will be described later.

(Mill pot shape)
As shown in FIGS. 1 to 4, the mill pot 31 has a substantially spherical appearance. Specifically, the flanges 31b and 31b of the hemispheres 31a and 31a with the stainless steel flanges 31b and 31b are overlapped to form the mill pot 31 (see FIGS. 3 and 4). The ball for grinding and the material to be ground are put in the mill pot 31 before this superposition. As with the appearance of the mill pot 31, the inner wall surface and the space surrounded by the inner wall surface are substantially spherical. Although it is not intended to obstruct shapes other than the spherical shape, by making it spherical, the efficiency of running along the wall surface of the object to be pulverized due to rotation is better than other shapes. Since it runs up efficiently, the material to be crushed can be crushed efficiently. In order to produce a kicking effect in addition to this running-up effect, the mill pot 31 of this embodiment forms a part of the inner wall surface on a flat surface (planar portion 3f) having a smaller curvature than the inner wall surface curvature. That is, a part is flattened. The object to be crushed is kicked up by the rotation of the flat portion, and the pulverization efficiency can be further increased.

(Attaching the mill pot)
As shown in FIGS. 1, 3 and 4, the spherical mill pot 31 is sandwiched and fixed between the support plates 11d and 11d. That is, with one support plate 11d attached to the frame 11c, the mill pot 31 is placed in the support hole 11h of the support plate 11d. At this time, the flanges 31b and 31b are inserted between the support plates 11d and 11d. When inserted in such a manner, the ring packing 11p abuts against the mill pot 31 and is supported in one piece. If an attempt is made to attach the other support plate 11d to the frame 11c while maintaining this state, a part of the mill pot 31 protrudes from the other support hole 11h and is supported by the other ring packing 11p. Here, if the other support plate 11d is screwed to the frame 11c, the mill pot 31 can be attached to the rotating body 11.

(Structure of driving force transmission device)
The driving force transmission device 21 serving as a driving source for the second rotating body 11 has, for example, the following structure. First, the driving force transmission device 21 mentioned as a first example first includes a driving disk 23 that is coaxially fixed so as not to rotate so as to rotate integrally with the first shaft 3 (horizontal shaft). Further, a driven disk 25 is provided which is non-rotatable on the second shaft 9 (vertical shaft) and is mounted perpendicular to the second axis. The second shaft 9 is arranged such that its axis (second axis) is orthogonal to the first axis of the first shaft 3, and the peripheral edge 24 of the main disk 23 is pressed against the plate surface 26 of the driven disk 25. It is configured to As a result, the rotational force of the first rotating body 5 rotating around the first shaft 3 (around the axis of the first shaft 3) by the driving device 7 is transmitted to the second rotating body 11 and transmitted to the second shaft 9 (vertical). Around the axis) (around the axis of the second axis 9).

  In the present embodiment, an elastic body 27 is provided on the peripheral edge 24 of the main disk 23. The elastic body 27 is for increasing the pressure contact force and the frictional force with respect to the plate surface 26 of the driven disk 25 by the elastic deformation, thereby reducing the loss of driving force transmission. An elastic body (not shown) may be provided on the plate surface 26 together with the peripheral edge 24, or an elastic body (not shown) may be provided only on the plate surface 26 without being provided on the peripheral edge 24. However, if it is determined that the elastic body 27 is not essential and is not necessary, the elastic body 27 is omitted and the peripheral edge 24 is directly pressed against the plate surface 26.

(Auxiliary disk)
In FIG. 1, the auxiliary disk 29 is indicated by a two-dot chain line. The auxiliary disk 29 is a small disk that is rotatably attached to the fixed shaft 30 fixed to the first rotating body 5. The auxiliary disk is disposed substantially parallel to the main disk 23 and at a position opposite to the main disk 23 with the second shaft 9 interposed therebetween. When the main rotating disk 23 is in contact only at one end of the second rotating body 11 (assuming that there is no auxiliary disk 29), the balance of the second rotating body 11 (driven disk 25) is lost and smooth rotation is achieved. There is also a risk that it will not be possible. In order to prevent this from happening and to balance the force applied to the second rotating body 11 from the main rotating disk 23, to ensure smooth rotation, the auxiliary disk 29 that comes into pressure contact with the second rotating body 11 and makes rolling contact. Was provided. However, if this is considered unnecessary, the auxiliary disk 29 can be omitted.

(Operational effect of this embodiment)
The effects of the present embodiment will be described with reference to FIGS. The rotation of the motor 7 rotates the rotating shaft 3b via the belt 8. The rotation of the rotating shaft 3b rotates the first rotating body 5 integrated therewith. At this time, the first rotating body 5 is also rotated with respect to the fixed shaft 3a. Thus, the first rotating body 5 rotates around the first axis 3L. The driving disk 23 coaxially fixed to the fixed shaft 3a does not rotate even when the first rotating body 5 rotates (FIGS. 5 (1) to (4)). The driven disk 25 rotates coaxially with the second shaft 9, and the second shaft 9 rotates with respect to the first rotating body 5. In addition to this, the driven disk 25 rotates around the first axis 3 </ b> L together with the first rotating body 5.

  Here, as shown in FIG. 5, when the driven disk 25 rotates around the first axis 3L (this rotation is referred to as “revolution”), the plate surface 26 of the main disk 23 with which it is in pressure contact is provided. Rolling contact with the peripheral edge 24 (elastic body 27) and rotating around the second axis 9L (this rotation is referred to as “autorotation”). In other words, as can be seen by looking at the positions of the black dots added to the main disk 23 and the driven disk 25 for marking, the driven disks that revolve while rotating without changing the positions of the black dots of the main disk 23. The position of the 25 black spots changes. Accordingly, the second rotating body 11 (mill pot 31) integrated with the driven disk 25 also revolves while rotating.

(Modification of drive device)
The first rotating body 5 can control (variable) the rotation speed by controlling the driving device 7. However, in the driving force transmission device 21 configured as described above, the rotational speed (V2) of the second rotating body 11 must always have a constant relationship with the rotational speed (V1) of the first rotating body 5. For example, V2 = kV1 (k is a constant). On the other hand, although the control is more complicated than a single drive source, variations (for example, changing the rotation speed of one and the other) are added to the rotation of the first rotating body 5 and the second rotating body 11 by individually driving. can do. The rotation variation enables mill pulverization according to the properties of the object to be crushed (hard and soft) and the pulverized state (coarse and fine pulverization). That is, the ball mill 1 ′ shown in FIG. 6 rotates the driven disk 23 ′ fixed so as to rotate coaxially with the rotating shaft 3′a by rotating the motor 7 ′, and the driven disk 25 is rotated by the rotational force. It is configured to rotate around the second axis 9L. The other points are the same as the structure of the ball mill 1.

(Modified mill pot)
A modification of the mill pot will be described with reference to FIG. The mill pot 60 is configured to include an inner pot 61 that accommodates an object to be crushed and an outer pot 71 that protects and surrounds the inner pot 61. The inner pot 61 is formed of a cylindrical pot body 63 having an upper opening and a lid 65 that closes the upper opening, and the former flange portion 63f and the latter flange portion 65f are overlapped and fixed with screws. It comes to be sealed. Any material can be used for the inner pot 61 as long as it can be used physically and chemically. In the present embodiment, it is zirconia. The reason for adopting zirconia is that it is convenient to prevent contamination.

  The outer pot 71 is formed of a cylindrical pot body 73 having an upper opening and a lid body 75 that closes the upper opening, and the former flange portion 73f and the latter flange portion 75f are overlapped and then screwed. It comes to be sealed. Any material can be used for the outer pot 71 as long as it can be used physically and chemically. In the present embodiment, the material is stainless steel. The reason for adopting stainless steel is that it is suitable for protecting the inner pot 61.

The reason why the mill pot 60 has a double structure is to further increase the safety of the inner pot 61 and thus the entire mill pot by the protective surrounding of the outer pot 71. In the first place, it is unthinkable that the mill pot itself will be damaged, but it is a safety measure that takes into consideration. Furthermore, it also has the meaning of protecting the inner pot itself from external forces.
