DETAILED DESCRIPTION OF THE INVENTION

[0027] A beating method and beating device according to one embodiment of the present invention will be described with reference to FIGS.

[0028] R shown in Figure 1 is a beating device. Beating device R 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 beater 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.

[0029] 1 is the main body, 2 is a rotating shaft provided on the main body 1, and 3 is a motor that drives the rotating 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 (beaten) in the beating section 4.

[0030] 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.

[0031] 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 attached by, for example, inserting a key K21 into a key groove K22 provided in the rotary shaft 3 and the rotary disk-shaped body .

[0032] The raw material supplied from the supply unit 5 to the beating unit 4 is beaten between the adjacent rotating plate-like body 42 and fixed plate-like body 41, and the beaten raw material is discharged from the discharge unit 6. The fixed plate-side opening 41a passes through the front and back of the fixed plate-like body 41, and the rotating plate-side opening 42a passes through the front and back of the rotating plate-like body 42.

[0033] Therefore, according to the above-mentioned beating device (screening device) R [beating method (screening device refining method)], the unbeaten raw material in the beating section 4 can move between the adjacent rotating plate-like body 42 and fixed plate-like body 41 via the fixed plate-side opening 41a and the rotating plate-side opening 42a, thereby lengthening the storage time of the processed raw material in the beating section 4 and enabling efficient processing.In addition, between the adjacent rotating plate-like body 42 and fixed plate-like body 41, for example, the raw material is beaten by contact between the adjacent rotating plate-like body 42 and fixed plate-like body 41 or by a narrow gap (for example, a few μ) between the adjacent rotating plate-like body 42 and fixed plate-like body 41, and the beaten fine raw material can be obtained from the discharge section 6.

[0034] In this embodiment, the multiple fixed plate-like bodies 41 and the multiple rotating plate-like bodies 42 are arranged so that the fixed plate-like bodies 41 and the 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. Therefore, 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, and the pulp that is not beaten 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.

[0035] 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 using 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)].

[0036] 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 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 via an unbeaten discharge section 9 provided in the main body 1.

[0037] According to this beating device R, raw material that is not beaten in the beating section 4 can move between the adjacent rotating plate-like body 42 and fixed plate-like body 41 via the fixed plate-side opening 41a and the rotating plate-side opening 42a, thereby lengthening the storage time of the raw material in the beating section 4 and enabling efficient processing.In addition, between the adjacent rotating plate-like body 42 and fixed plate-like body 41, for example, the raw material is beaten by contact between the adjacent rotating plate-like body 42 and fixed plate-like body 41 or by a narrow gap between the adjacent rotating plate-like body 42 and fixed plate-like body 41, and beaten fine raw material can be obtained from the discharge section 6.Furthermore, raw material that is 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.

[0038] 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. In other words, of the beating section 4 having multiple fixed plate-like bodies 41 and multiple 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 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 raw material from the supply portion (symbol 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 (symbol 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.

[0039] The rotating plate-shaped body 42 and the fixed plate-shaped body 41 may be made of chromium-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 body 41 and rotating plate-shaped body 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)].
