[0009] The pulverization apparatus 1 of this embodiment will be described in detail with reference to the drawings.

[0010] Figure 1 is a front view showing a micronizing apparatus 1 according to an embodiment of the present invention. Figure 2 is a partially enlarged view showing the blade member 10 and screw member 12 in the micronizing apparatus 1 of this embodiment. Figure 3 is a skeleton block diagram showing the entire system of the micronizing apparatus 1 of this embodiment. In this embodiment, as shown in Figure 2, the rotation direction of the rotating shaft 5 is defined as rotation direction A, with the tip of the arrow pointing to the front and the rear end pointing to the rear. The direction from upstream to downstream of the rotating shaft 5 is defined as the rotation direction axis B, with upstream and downstream being the directions in which the material moves, with the tip of the arrow pointing to the downstream and the rear end pointing to the upstream.

[0011] The pulverization apparatus 1 of this embodiment comprises a machine base 2, a cylindrical pulverization container 3 positioned horizontally on the machine base 2, a motor 8 as a drive source installed on the machine base 2, a rotating shaft 5 rotated by the motor 8, a plurality of blade members 10 arranged on the rotating shaft 5 inside the pulverization container 3, a material input section 14 for inputting material, and a screw member 12 for discharging the material input section 14 from the pulverization container 3. The material input section 14 has an upper hopper 14a and a material inlet section 14b located below the hopper 14a, flanking an opening / closing section 15.

[0012] Furthermore, the bottom wall of the pulverization container 3 is provided with an outlet cover 17 for removing the molten material. The outlet cover 17 is rotatably supported by a shaft 18, and the shaft 18 is connected to rotary cylinders 19, 19, and is configured to be opened and closed. Note that the outlet cover 17 is not limited to the bottom wall, but may also be provided on the top wall or side wall.

[0013] The motor 8 is driven by a power source (not shown). The motor 8 transmits the driving force to the rotating shaft 5 and rotates the blade member 10 and the screw member 12 via the rotating shaft 5. The motor 8 can control the rotational speed within a range where the tip peripheral speed of the blade member 10 is between 5 m / s and 50 m / s. Also, the output shaft of the motor 8 and the rotating shaft 5 are connected by a V-belt 7 that can slip so that when a sudden fluctuation in load torque occurs in the rotating shaft 5, the load torque is not transmitted to the motor 8. Note that the output shaft of the motor 8 and the rotating shaft 5 may be connected via a brake or a clutch, etc. Also, the rotating shaft 5 may be formed coaxially with the output shaft of the motor 8.

[0014] The rotating shaft 5 is horizontally supported by bearings 4, 4 and is inserted and disposed coaxially with the center of the pulverization container 3. One end of the rotating shaft 5 is rotationally connected to a motor 8 as a driving source via a pulley 6 and a V-belt 7. The rotating shaft 5 is hollow with a small-diameter hole for supplying cooling water formed in its axial center portion, and rotary joints 9 are provided at both ends thereof, and the cooling water is configured to be supplied axially into the interior of the rotating shaft 5 through the rotary joints 9.

[0015] On the outer periphery of the rotating shaft 5 disposed through the pulverization container 3, as shown in FIG. 2, there are a total of six blade members 10a to 10f whose cross-sectional shape is rectangular and whose overall shape is rectangular. They project radially at angular intervals of 180 degrees in the circumferential direction of the rotating shaft 5 with a space in the axial direction. As shown in FIG. 2, the thickness of the blade members 10a to 10f is formed such that approximately 40% of the outer peripheral side portion is thicker than the inner peripheral side, and they are configured such that pulverization is effectively performed. Note that the outer peripheral side of the blade member 10 may not be formed thicker, and the inner peripheral side and the outer peripheral side may be formed with the same width and thickness.

[0016] Of these, the blade members 10a and 10f at both axial ends are fixed to the outer periphery of the rotating shaft 5 while being inclined at an attachment angle of approximately 15 degrees from the tip to the root of the blade member 10 so that when rotating in the counterclockwise rotation direction A when viewed from the right side surface of FIG. 2, their leading edges are in almost contact with the inner surfaces of the vertical walls 11, 11 at both ends of the pulverization container 3 with almost no gap.

[0017] Furthermore, the four intermediate blade members 10b, 10c, 10d, and 10e are fixed to the outer surface of the rotating shaft 5 in a staggered pattern, inclined from the tip to the base of each blade, and are arranged so that their trailing edges face both ends of the pulverization container 3 during rotation. In other words, as shown in Figure 2, the four blade members 10b, 10d, 10c, and 10e are positioned on the rotating shaft 5 at a mounting angle (angle relative to the circumferential direction) of 15 degrees, so that they face each other in the axial direction and the distance between them narrows in the rotational direction.

[0018] In the direction of the rotating shaft 5, the side of the pulverization container 3 opposite the motor 8 is the material pulverization section 3a, and the side facing the motor 8 is the material discharge section 3b. The material pulverization section 3a surrounds the blade member 10 fixed to the rotating shaft 5. The material discharge section 3b surrounds the helical screw member 12 formed on the outer circumference of the rotating shaft 5.

[0019] A material input section 14 is provided above the material pulverization section 3a. After the material is introduced into the material input section 14, an openable / closable opening / closing section 15 is provided that can be airtightly closed during pulverization. In addition, a pair of balance wheels 16 are installed on both sides of the blade member 10 and screw member 12 of the rotating shaft 5 to ensure smooth rotation.

[0020] The material introduced into the material pulverization section 3a is pulverized by the blade member 10 within the material pulverization section 3a. The pulverized material is moved downstream by the screw member 12 within the material discharge section 3b. The material that has been pulverized in the material pulverization section 3a and moved to the material discharge section 3b is removed by opening the discharge port cover 17. Alternatively, the material may be discharged from the material pulverization section 3a by providing the discharge port cover 17 in the material pulverization section 3a, without using the material discharge section 3b and the screw member 12.

[0021] As shown in Figure 3, a continuous water passage 24 is formed in the peripheral wall of the pulverization container 3 and in the center of the rotating shaft 5, and a cooling section 22 is configured that can cool the peripheral wall of the pulverization container 3 and the rotating shaft 5 by circulating cooling water. In the cooling section 22, the water is cooled by the cooling tower 23, and the cooling water is used to cool the pulverization container 3, the rotating shaft 5, etc., and then returned to the cooling tower 23.

[0022] Furthermore, the collars 20, 20 on both sides shown in Figure 2 are for sending air to the pulverization container 3. The continuous grooves at each end are composed of right-hand and left-hand threaded helical grooves, respectively, so that air is sent to the pulverization container 3 by the rotation of the rotating shaft 5.

[0023] Furthermore, the control panel 21 shown in Figure 1 is connected to the motor 8 via a connecting cable, and the load torque of the spindle from the motor 8 is continuously input as an electrical signal. The control panel 21 may also be configured to automatically remove the pulverized material based on changes in the load torque acting on the spindle of the motor 8 according to the pulverization and drying state of the material in the pulverization container 3.

[0024] A method for pulverizing a material using the pulverizing device 1 of this embodiment will now be described. The user places the material into the material pulverization section 3a of the pulverizing container 3 via the material input section 14 of the pulverizing device 1, drives the motor 8, and rotates the rotating shaft 5, the blade member 10, and the screw member 12 to finely pulverize the material. When the blade member 10 is rotated at high speed, the inside of the pulverizing container 3 becomes a high-temperature dry state due to the movement of the material itself and the friction caused by the collision and shearing of the materials, and the material is made fine. The pulverized material is removed by opening the discharge cover 17 from the material discharge section 3b.

[0025] Next, the blade member 10 of this embodiment will be described. For the sake of ease of understanding, the rotation direction A and the rotation direction axis B will be defined as shown in the drawings in the following description of the blade member 10 of this embodiment. However, in reality, as shown in Figure 2, the blade member 10 is inclined with respect to the rotation direction A and the rotation direction axis B.

[0026] Figure 4 shows a three-view drawing of the blade member 10 of the first embodiment of the pulverization device 1. Figure 4(a) is a view from the downstream side in the rotation axis direction B, Figure 4(b) is a view from the left side of Figure 4(a), and Figure 4(c) is a view from the right side of Figure 4(a). Figure 5 shows an assembly drawing of the blade member 10 of the first embodiment of the pulverization device 1.

[0027] The blade member 10 of the first embodiment includes a blade base 100 disposed on the rotating shaft 5, a blade tip 101 that is detachably attached to the blade base 100, and a bolt 102 that serves as a retaining part for attaching the blade tip 101 to the blade base 100.

[0028] The blade base 100 is fixed to the rotating shaft 5 by welding or the like. A guide portion 100a is formed on the front side of the tip of the blade base 100 in the direction of rotation A (right side of the paper in Figure 4(a)), which is a T-shaped concave section in a cross section perpendicular to the rotating shaft 5. The upper horizontal bar of the guide portion 100a is formed along the direction of rotation axis B. A first screw hole 100b is formed on the rear side of the guide portion 100a in the direction of rotation A (left side of the paper in Figure 4(a)). The first screw hole 100b has an enlarged diameter hole portion 100b1 that houses the head 102a of the bolt 102.

[0029] The blade tip 101 is detachably attached to the end of the blade base 100 opposite to the rotation axis 5. The blade tip 101 includes a tip body 101a that contacts the material, and a projection 101b that is guided by a guide 100a when removed from the blade base 100. The tip body 101a is rectangular in shape, with a width longer parallel to the rotation direction A than the blade base 100, and a thickness greater in the rotation axis direction B. The projection 101b protrudes from the tip body 101a in a T-shape in a cross section perpendicular to the rotation axis 5. A second screw hole 101b1 is formed on the rear side of the projection 101b in the rotation direction A.

[0030] In the first embodiment of the blade member 10, as shown in Figure 5, the blade tip portion 101 is attached to the blade base portion 100. First, the user inserts the protruding portion 101b of the blade tip portion 101 into the guide portion 100a of the blade base portion 100. Next, the user moves the blade tip portion 101 in the direction of arrow C. The protruding portion 101b is fitted in until it abuts against the wall portion 100a1 of the guide portion 100a in which the first screw hole 100b is formed. Next, the user screws the bolt 102 into the first screw hole 100b and the second screw hole 101b1 from the direction of arrow D.

[0031] In the first embodiment of the blade member 10, the blade tip 101 is detached from the blade base 100 by moving it in the opposite direction of arrow C in Figure 5. First, the user removes the bolt 102 from the first screw hole 100b and the second screw hole 101b1 in the opposite direction of arrow D. Next, the user moves the blade tip 101 in the opposite direction of arrow C and detaches the protruding portion 101b of the blade tip 101 from the guide portion 100a of the blade base 100.

[0032] Thus, in the first embodiment, the blade member 10 has a structure in which the blade tip 101 is removable from the blade base 100, eliminating the need to remove the entire shaft when repairing or replacing wear, thus saving costs and time. Furthermore, by immediately replacing the blade member 10, the pulverization device 1 can operate without fluctuations in the pulverization process, shear, or friction heat generation conditions, thus preventing a decrease in reproducibility during mass production. Moreover, there is no need to restrict the materials used to suppress wear of the blade member 10.

[0033] Figure 6 shows a four-view drawing of the blade member 10 of the pulverization device 1 of the second embodiment. Figure 6(a) is a view from the downstream side in the rotation axis direction B, Figure 6(b) is a view from the left side of Figure 6(a), Figure 6(c) is a view from the right side of Figure 6(a), and Figure 6(d) is a view from the tip side of the blade member. Figure 7 shows an assembly drawing of the blade member 10 of the pulverization device 1 of the second embodiment.

[0034] The blade member 10 of the second embodiment includes a blade base 100 disposed on the rotating shaft 5, a blade tip 101 that is detachably attached to the blade base 100, and a bolt 102 that serves as a retaining part for attaching the blade tip 101 to the blade base 100.

[0035] The blade base 100 is fixed to the rotating shaft 5 by welding or the like. A notch is formed on the front side of the tip of the blade base 100 in the direction of rotation A (right side of the paper in Figure 6(a)). On the blade base 100 on the rotating shaft 5 side of the notch, a guide portion 100a is formed, which is T-shaped concave in a cross section perpendicular to the rotating shaft 5. The part of the guide portion 100a corresponding to the upper horizontal bar of the T is formed on the rotating shaft 5 side. In addition, a fitting recess 100c is formed on the rear side of the blade base 100 in the direction of rotation A of the notch. The fitting recess 100c may be a rectangular parallelepiped-shaped hole. A first screw hole 100b is formed on the tip side of the fitting recess 100c. The first screw hole 100b extends from the tip of the wing base 100 to the fitting recess 100c, and has an enlarged diameter hole 100b1 at its tip that accommodates the head 102a of the bolt 102.

[0036] The blade tip 101 is detachably attached to a notch formed on the front side of the blade base 100, opposite to the rotation axis 5 and in the direction of rotation A. The blade tip 101 includes a tip body 101a that contacts the material, a projection 101b that is guided by a guide 100a when removed from the blade base 100, and a fitting projection 101c that is fitted into a fitting recess 100c when removed from the blade base 100. The tip body 101a is rectangular parallelepiped and is formed flush with the blade base 100. The tip body 101a may protrude further forward and backward in the direction of rotation A than the blade base 100, and its thickness in the direction of rotation axis B may be greater. The projection 101b protrudes from the tip body 101a toward the rotation axis 5 in a T-shape in a cross section perpendicular to the rotation axis 5. A second screw hole 101c1 is formed at the tip of the recessed projection 101c.

[0037] In the second embodiment of the blade member 10, as shown in Figure 7, the blade tip portion 101 is attached to the blade base portion 100. First, the user inserts the protruding portion 101b of the blade tip portion 101 into the guide portion 100a of the blade base portion 100. Next, the user moves the blade tip portion 101 in the direction of arrow E. Once the protruding portion 101b is guided by the guide portion 100A, the fitting projection portion 101c is fitted into the fitting recess portion 100c. Next, the user screws the bolt 102 into the first screw hole 100b and the second screw hole 101c1 from the direction of arrow F.

[0038] In the second embodiment of the blade member 10, the blade tip 101 is removed from the blade base 100 by moving it in the opposite direction of the arrow in Figure 7. First, the user moves the bolt 102 in the opposite direction of arrow F and removes it from the first screw hole 100b and the second screw hole 101c1. Next, the user moves the blade tip 101 in the opposite direction of arrow E and removes the protruding part 101b of the blade tip 101 from the guide part 100a of the blade base 100.

[0039] Thus, in the second embodiment, the blade member 10 has a structure in which the blade tip 101 is removable from the blade base 100, eliminating the need to remove the entire shaft when repairing or replacing wear, thus saving costs and time. Furthermore, by making the replaceable blade tip 101 smaller, costs and time during replacement can be further reduced. In addition, by immediately replacing the blade member 10, the pulverization device 1 can operate without fluctuations in the pulverization conditions, shear, or frictional heat generation conditions, thus preventing a decrease in reproducibility during mass production. Moreover, there is no need to restrict the materials used to suppress wear of the blade member 10.

[0040] Figure 8 shows four views of the blade member 10 of the pulverization device 1 of the third embodiment. Figure 8(a) is a view from the downstream side in the rotation axis direction B, Figure 8(b) is a view from the left side of Figure 8(a), Figure 8(c) is a view from the right side of Figure 8(a), and Figure 8(d) is a view from the tip side of the blade member. Figure 9 shows an assembly diagram of the blade member 10 of the pulverization device 1 of the third embodiment.

[0041] The blade member 10 of the third embodiment includes a blade base 100 disposed on the rotating shaft 5, a blade tip 101 that is detachably attached to the blade base 100, and a bolt 102 that serves as a retaining part for attaching the blade tip 101 to the blade base 100.

[0042] The blade base 100 is fixed to the rotating shaft 5 by welding or the like. A notch is formed on the front side of the tip of the blade base 100 in the direction of rotation A (right side of the paper in Figure 8(a)) and on the downstream side and tip side in the direction of rotation axis B. A guide portion 100a is formed on the blade base 100 on the upstream side of the notch in the direction of rotation axis B, which is trapezoidal in shape in a cross section parallel to the direction of rotation axis B. The part of the guide portion 100a corresponding to the base of the trapezoid is formed on the upstream side of the direction of rotation axis B. A first screw hole 100b is formed in at least one of the blade base 100 on the upstream side of the notch in the direction of rotation axis B and on the upstream side of the guide portion 100a in the direction of rotation axis B (right side of the paper in Figure 8(c)).

[0043] The blade tip 101 is detachably attached to the front side of the blade base 100 in the direction of rotation A opposite to the rotation axis 5 (right side of the paper in Figure 8(a)) and downstream side in the direction of rotation axis B, as well as to the tip. The blade tip 101 includes a tip body 101a that contacts the material, a trapezoidal projection 101b that is guided by a guide part 100a when removed from the blade base 100, and a tip projection 101d that protrudes in an L-shape from the tip of the tip body 101a. The tip body 101a is formed as a planar rectangular parallelepiped. The projection 101b protrudes from the tip body 101a in a trapezoidal shape. The tip projection 101d is formed as a plate-shaped rectangular parallelepiped and protrudes from the tip of the tip body 101a in the same direction as the projection 101b. A second screw hole 101a1 is formed in the tip body 101a and the projection 101b. The second screw hole 101a1 has an enlarged diameter hole portion 101a2 that accommodates the head 102a of the bolt 102.

[0044] In the third embodiment of the blade member 10, as shown in Figure 9, the blade tip portion 101 is attached to the blade base portion 100. First, the user inserts the protruding portion 101b of the blade tip portion 101 into the guide portion 100a of the blade base portion 100. Next, the user moves the blade tip portion 101 in the direction of arrow G. The protruding portion 101b is fitted in until it abuts against the wall portion 100a1 of the guide portion 100a. Next, the user screws the bolt 102 into the second screw hole 101b1 and the first screw hole 100b from the direction of arrow H.

[0045] In the third embodiment of the blade member 10, the blade tip 101 is removed from the blade base 100 by moving it in the opposite direction of the arrow in Figure 9. First, the user removes the bolt 102 from the first screw hole 100b and the second screw hole 101b1 in the opposite direction of arrow H. Next, the user moves the blade tip 101 in the opposite direction of arrow G, and removes the protruding part 101b of the blade tip 101 from the guide part 100a of the blade base 100.

[0046] Thus, in the third embodiment, the blade member 10 has a structure in which the blade tip 101 is removable from the blade base 100, eliminating the need to remove the entire shaft when repairing or replacing wear, thus saving costs and time. Furthermore, by making the replaceable blade tip 101 small, costs and time during replacement can be further reduced. In addition, by immediately replacing the blade member 10, the pulverization device 1 can operate without fluctuations in the pulverization conditions, shear, or frictional heat generation conditions, thus preventing a decrease in reproducibility during mass production. Moreover, there is no need to restrict the materials used to suppress wear of the blade member 10.

[0047] In this embodiment, the blade base 100 has a concave guide portion 100a and the blade tip 111 has a protruding portion 101b that is guided by the guide portion 100a. However, the embodiment is not limited to this, and one of the blade base 100 or the blade tip 111 may have a concave guide portion 100a, and the other of the blade base 100 or the blade tip 111 may have a protruding portion 101b that is guided by the guide portion 100a.

[0048] The shape of the protruding portion 101b and the guide portion 100a is not limited to a T-shaped or trapezoidal cross-section, but may be any other shape. The position of the protruding portion 101b and the guide portion 100a may be anywhere, and there may be any number of protruding portions 101b and guide portions 100a.

[0049] In this embodiment, the blade tip portion 101 is preferably made of a material with multiple different hardnesses so that it can be selected based on the hardness of the material. The material of the blade tip portion 101 should be selected according to the hardness of the material. For example, for resin materials, it is preferable to use a material with a Mohs hardness of 5 or higher, such as steel. Furthermore, for harder materials, a harder material should be selected and used.

[0050] As described above, the pulverization apparatus 1 of this embodiment comprises a motor 8 that generates driving force, a rotating shaft 5 that rotates by the motor 8, a plurality of blade members 10 formed on the outer circumference of the other side in the axial direction of the rotating shaft 5, a material input section 14 into which material is introduced, and a pulverization container 3 connected below the material input section 14, through which the rotating shaft 5 passes, and for mixing and melting the material introduced into the material input section 14. The blade members 10 have a blade base 100 disposed on the rotating shaft 5 and a blade tip 101 that is detachably attached to the blade base 100.

[0051] Therefore, in this embodiment, the pulverization apparatus 1 has a structure in which the blade tip portion 101 of the blade member 10 is removable from the blade base portion 100, eliminating the need to remove the entire shaft when repairing or replacing wear, thus saving both time and money. Furthermore, by immediately replacing the blade member 10, the pulverization apparatus 1 maintains consistent pulverization conditions, shear, and frictional heat generation conditions, without reducing reproducibility during mass production. Moreover, there is no need to restrict the materials used to suppress wear on the blade member 10.

[0052] Furthermore, in the pulverization device 1 of this embodiment, the blade member 10 has a bolt 102 as a holding part for attaching the blade base 100 and the blade tip 101. Therefore, the pulverization device 1 of this embodiment can properly attach the blade base 100 and the blade tip 101.

[0053] Furthermore, in the pulverizing device 1 of this embodiment, one of the blade base portion 100 or the blade tip portion 101 has a concave guide portion 100a, and the other of the blade base portion 100 or the blade tip portion 101 has a protruding portion 101b that is guided by the guide portion 100a. Therefore, the pulverizing device 1 of this embodiment allows for smooth replacement of the blade tip portion 101.

[0054] Furthermore, in the pulverization apparatus 1 of this embodiment, if the rotation direction of the rotating shaft 5 is rotation direction A, and the direction in which the material moves from upstream to downstream of the rotating shaft 5 is rotation direction axis B, then a notch is formed on the front side of the tip of the blade base 100 in the rotation direction A, and the blade tip 101 fits into the notch. Therefore, the pulverization apparatus 1 of this embodiment can further reduce the cost and time of replacement by making the replaceable blade tip 101 smaller. In addition, the material can be properly brought into contact with the replaceable blade tip 101.
