A recess 3b1 of the rotating body 3 is formed at the tip of the rotating body 3, and the opening of the recess 3b1 of the rotating body 3 and the opening of the raw material inlet 2a are opposed to each other. In the concave portion 3b1 of the rotating body 3, a raw material introduction portion 2d is provided on the inner wall of the casing 2 so as to be tapered so that the paper raw material from the raw material inlet 2a is directed. Then, as shown in FIG. 2, the opening of the raw material introduction portion 2d and the concave portion 3b1 of the rotating body 3 face each other, and the opening of the raw material introduction portion 2d on the side of the concave portion 3b1 is formed larger than the opening of the concave portion 3b1.

When passing through the gap formed between the fixing portion 5A and the first irregularity rotating portion 4A and the first irregularity fixing portion 5A, the papermaking raw material in the second passage 2c2 is separated by the second irregularity. When passing through the gap formed between the rotating portion 4B and the second uneven fixing portion 5B, the second uneven uneven rotating portion 4B and the second uneven fixing portion 5B disintegrate.

As a result, according to the disintegrator of the present embodiment, the papermaking raw material has the uneven shape provided on both surfaces of the rotating portion 4 and the fixed portion 5 provided on the inner wall of the casing 2. Since it is disintegrated, it is possible to disintegrate a large amount of papermaking raw material without increasing the size of the rotating part in the radial direction, as compared with the conventional one in which papermaking raw material is disintegrated only on one side of the rotating part. Is disintegrated on both sides of the rotating part 4 when the rotating body 3
Without opening the rotating part 4 attached to the tip of
The opening of the recess 3b1 formed at the tip of the rotating body 3 is opposed to the opening of the raw material inlet 2a, and the opening of the recess 3b1 and the second passage 2c2 communicate with each other by the rotating body passage 3b2. 3, a large amount of papermaking raw material can be disintegrated without increasing the size of the rotating portion in the radial direction, and the papermaking raw material from the raw material inlet 2a is rotated by the rotating body 3. Of the second passage 2 which is received by the concave portion 3b1 and is located on the side far from the raw material inlet 2a.
Since the papermaking raw material can be easily introduced into c2, a large amount of papermaking raw material can be disintegrated. Further, when the papermaking raw material is disintegrated, the rotating body 3 receives opposing forces from both surfaces of the rotating section 4, so that the papermaking raw material can be disintegrated. The thrust is balanced and thrust loss is small compared to the conventional disintegrator that disintegrates only one surface of the rotating unit 4.

[0031]

According to the first aspect of the present invention, the papermaking raw material is disintegrated in the uneven shape provided on both surfaces of the rotating portion and the uneven portion provided on the inner wall of the casing. Therefore, compared to the conventional method in which the papermaking raw material is disintegrated only on one side of the rotating section, a larger amount of papermaking raw material can be disintegrated without increasing the size of the rotating section in the radial direction. When disintegrating on both surfaces, without opening the rotating part attached to the tip of the rotating body, the opening of the concave portion formed at the tip of the rotating body is opposed to the opening of the raw material inlet,
Since the opening of the concave portion and the second passage communicate with each other by the rotating body passage, the size of the rotating part in the radial direction is not increased as compared with the case where the rotating part attached to the tip of the rotating body is opened. A large amount of papermaking raw material can be disintegrated, and the papermaking raw material from the raw material inlet is received in the concave portion, and the papermaking raw material is easily introduced into the second passage located on the side far from the raw material inlet to disintegrate many papermaking raw materials. Further, when disintegrating the papermaking raw material, the rotating body receives opposing forces from both surfaces of the rotating part, so that the thrust is balanced compared to the conventional one in which the papermaking raw material is disintegrated on only one side of the rotating part. Thus, a disintegrator with a small thrust loss can be obtained.

According to the second aspect of the present invention, in addition to the effects of the first aspect of the present invention, the papermaking raw material guided from the raw material inlet is directed toward the concave portion of the rotating body by the raw material introduction section. In addition, the opening of the raw material introduction section on the side of the concave portion of the rotating body is formed larger than the opening of the concave section of the rotating body. In other words, the opening of the concave section of the rotating body is formed on the side of the raw material introduction section on the side of the concave section of the rotating body. Therefore, the papermaking raw material is guided to the first passage and the papermaking raw material guided from the raw material inlet can be efficiently divided into the first passage and the second passage.

Further, according to the disintegrator according to the third aspect, in addition to the effect of the above-described first aspect, by forming a plurality of second passages, a large number of flow passages of the second passages can be secured. Thus, a large amount of papermaking raw material can be disintegrated in the second passage.

According to the fourth aspect of the present invention, in addition to the effect of the first aspect, the papermaking raw material colliding with the bottom surface of the concave portion is guided to the rotary member passage so that the second material is formed.
Many papermaking raw materials can be disintegrated in the passage.
