The beating method and beating device of one embodiment of the present invention will be described with reference to Figures 1 to 7.

R shown in Figure 1 is a beating device, which can beat raw materials (e.g., pulp) more finely. For example, pulp adjusted to a concentration of approximately 2.0% to 6.0% by weight can be beaten in the beating device R to obtain cellulose nanofibers.
The beating device R of this embodiment defibrates and refines the raw material (for example, pulp), and therefore can also be called a screening device.

Reference numeral 1 denotes a main body, 2 denotes a rotary shaft provided on the main body 1, and 3 denotes a motor that drives the rotary shaft 2.
Reference numeral 4 denotes a beating section provided within the main body 1, 5 denotes a supply section that supplies raw material to the beating section 4, and 6 denotes a discharge section that discharges the raw material that has been beaten (thawed) in the beating section 4.

The beating section 4 has a plurality of fixed plate-shaped bodies 41 and a plurality of rotating plate-shaped bodies 42 (e.g., rotating disk-shaped bodies), and the plurality of fixed plate-shaped bodies 41 have fixed plate-side openings 41a and are attached so as to allow longitudinal movement of the rotating shaft 3, and movement of the rotating shaft 2 in the rotational direction is regulated by a main body-side regulating member K1 attached to the main body 1.
For example, the rotation of the fixed plate-shaped body 41 is prevented by the main body side regulating member K1 at the protrusion 41b of the fixed plate-shaped body 41.

In addition, each of the multiple rotating disk-shaped bodies 42 has a rotating disk-side opening 42a and is attached so as to allow longitudinal movement of the rotating shaft 3, and movement of the rotating shaft 2 in the rotational direction is regulated by a rotating shaft-side regulating member K2 attached to the rotating shaft 3.
The rotary shaft side restricting member K2 can be secured by, for example, inserting a key K21 into a key groove K22 provided in the rotary shaft 3 and the rotary disk-shaped body 42.

The raw material supplied to the beating section 4 from the supply section 5 is beaten between the adjacent rotating platen-shaped body 42 and fixed platen-shaped body 41, and the beaten raw material is discharged from the discharge section 6. The fixed platen-side opening 41a penetrates the front and back of the fixed platen-shaped body 41, and the rotating platen-side opening 42a penetrates the front and back of the rotating platen-shaped body 42.

Accordingly, according to the above-described beating device (screening device) R [beating method (screening device refining method)], unbeaten raw material in the beating section 4 can move between the adjacent rotating disks 42 and fixed disks 41 via the fixed disk side opening 41a and the rotating disk side opening 42a, thereby lengthening the storage time of the raw material in the beating section 4 and enabling efficient processing. Furthermore, the raw material can be beaten between the adjacent rotating disks 42 and fixed disks 41, for example, when the adjacent rotating disks 42 and fixed disks 41 come into contact with each other or through a narrow gap (e.g., a few microns) between the adjacent rotating disks 42 and fixed disks 41, and the beaten fine raw material can be obtained from the discharge section 6.

In this embodiment, the multiple fixed plate-like bodies 41 and multiple rotating plate-like bodies 42 are arranged so that the fixed plate-like bodies 41 and rotating plate-like bodies 42 are alternately positioned, and adjacent fixed plate-side openings 41a and rotating plate-side openings 42a are connected in the longitudinal direction of the rotating shaft 2. As a result, the pulp is beaten when adjacent rotating plate-like bodies 42 and fixed plate-like bodies 41 come into contact with each other or through narrow gaps between adjacent rotating plate-like bodies 42 and fixed plate-like bodies 41. Unbeaten pulp is beaten through narrow gaps between adjacent rotating plate-like bodies 42 and fixed plate-like bodies 41 via the rotating plate-side openings 42a. Sequentially, the pulp is beaten through narrow gaps between adjacent rotating plate-like bodies 42 and fixed plate-like bodies 41 via the rotating plate-side openings 42a, and beaten cellulose nanofibers can be obtained from the discharge section 6.

In addition, among the beating section 4 having a plurality of fixed plate-like bodies 41 and a plurality of rotating plate-like bodies 42, a pressing means (e.g., an air cylinder) 7 is provided which abuts against the fixed plate-like body 41 located on the side farthest from the motor 3 and presses it toward the motor 3, and a pressing force adjustment means 8 is provided which adjusts the pressing force of this pressing means 7.
Therefore, it is possible to obtain a fine raw material beaten to a desired value by adjusting the pressing force of the pressing means 7 using the pressing force adjusting means 8. For example, if fine cellulose cannot be obtained with the current beating method, the pressing force of the pressing means 7 can be adjusted to be stronger using the pressing force adjusting means 8 [Fig. 3(a)]. Conversely, if the current beating method results in cellulose that is too fine, the pressing force of the pressing means 7 can be adjusted to be weaker using the pressing force adjusting means 8 [Fig. 3(b)].

Of the beating section 4, which has multiple fixed plate-like bodies 41 and multiple rotating plate-like bodies 42, the innermost fixed plate-like body X (41) is located closest to the motor 3, and the multiple fixed plate-like bodies 41 and multiple rotating plate-like bodies 42 are arranged side by side so as to be perpendicular to the rotation axis 2, and the outer surfaces of the multiple side by side fixed plate-like bodies 41 and multiple rotating plate-like bodies 42 on the side farther from the rotation axis 2 are outer surface portion Y, and the raw material from the supply section 5 is supplied toward the innermost fixed plate-like body X (41), and the raw material beaten from the beating section 4 flows from outer surface portion Y toward the discharge section 6 (see Figures 2 and 3).
Raw material that is not beaten in the beating section 4 is discharged to the outside of the beating section 4 through an unbeaten discharge section 9 provided in the main body 1.

With this beating device R, unbeaten raw material in the beating section 4 can move between the adjacent rotating platen 42 and fixed platen 41 via the fixed platen side opening 41a and the rotating platen side opening 42a, thereby extending the storage time of the raw material in the beating section 4 and enabling efficient processing. Furthermore, the raw material is beaten between the adjacent rotating platen 42 and fixed platen 41, for example, when the adjacent rotating platen 42 and fixed platen 41 come into contact with each other or through a narrow gap between the adjacent rotating platen 42 and fixed platen 41, and fine beaten raw material can be obtained from the discharge section 6. Furthermore, raw material not beaten in the beating section 4 can be discharged from the unbeaten discharge section 9 provided in the main body 1, improving beating efficiency.

Although the raw material supply section 5 and discharge section 6 shown in FIG. 1 are not shown, the supply section 5 and discharge section 6 may be configured in reverse.
That is, of the beating section 4 having a plurality of fixed plate-like bodies 41 and a plurality of rotating plate-like bodies 42, the innermost fixed plate-like body X (41) is located on the side closest to the motor 3, and the plurality of fixed plate-like bodies 41 and the plurality of rotating plate-like bodies 42 are arranged side by side so as to be perpendicular to the rotation axis 2, and the outer surfaces of the arranged plurality of fixed plate-like bodies 41 and the plurality of rotating plate-like bodies 42 on the side farther from the rotation axis 2 are outer surface portion Y, and raw material from the supply portion (reference number 6 in Figure 2) is supplied toward outer surface portion Y, and the raw material beaten from the beating section 4 flows from the fixed plate side opening 41a of the innermost fixed plate-like body X (41) toward the discharge portion (reference number 5 in Figure 2), and the raw material that is not beaten in the beating section 4 is discharged outside the beating section 4 through the unbeaten discharge portion 9 provided in the main body 1.

The rotating plate 42 and the fixed plate 41 may be made of chrome-nickel steel, but are preferably made of wear-resistant ceramics.
If the rotating plate-shaped body 42 and the fixed plate-shaped body 41 are made of wear-resistant ceramics, even if adjacent rotating plate-shaped bodies 42 and 41 come into contact with each other, it is possible to prevent metal pieces such as chromium-nickel steel from being mixed into the raw material being processed.
The multiple outer peripheral shapes of either one of the adjacent fixed plate-shaped bodies 41 and rotating plate-shaped bodies 42 may be replaced with those shown in Figure 6(a) and formed into an uneven portion 42b along the outer periphery of the plate-shaped body [in this embodiment, the rotating plate-shaped body 42 shown in Figure 7(a)].
