素子に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refiner element that is highly efficient in refining or beating fibrous materials.

て好ましい抄紙特性及び製品特性を獲得する。 In the paper manufacturing process, mechanical processing steps called beating and refining are very important steps, and it is no exaggeration to say that paper is made by mechanical processing. In this process, the fibers are subjected to actions such as disintegration, swelling, fibrillation, cutting, etc., and gradually become flexible, thereby acquiring desirable paper-making properties and product properties.

る。 Among mechanical treatments, beating generally refers to the mechanical treatment of fibers that have already been defibrated by chemical treatment, etc., and the pulp concentration is usually 10% or less. The concept of refining is relatively new and was introduced after the introduction of disk refining, and it has a defibrating action as well as a defibrating action. Another feature of this treatment is that the pulp concentration during treatment can be increased to about 50%. However, it is common to use disc refining in the mechanical treatment of chemical pulp in the low concentration range, and in this case, refining and beating are synonymous. Therefore, at present, refining is often used in a meaning that includes the general mechanical treatment of fiber raw materials or fibers for paper manufacturing, and hereinafter, refining will be interpreted and used in a broad sense.
リフアイナーを大別するとデイスク型、コニカ
ル型、ドラム型の３種がある。デイスク型リフア

間の狭い間隙を通過する際に前記動作面によつて
リフアイニングされる。 There are three types of refiners: disc type, conical type, and drum type. A disc-type refiner usually consists of two opposing discs, to which are attached a metal working surface constituted by a blade and a groove. One or both of the disks rotate and the fiber suspension is refined by the working surfaces as it passes through the narrow gap between the two disks.
コニカル型リフアイナーはシエルとシエルの内
側で回転するローターから成り、シエルとロータ
ーの両方に金属製動作面を有する。 A conical refiner consists of a shell and a rotor that rotates inside the shell, with both the shell and rotor having metal working surfaces.

るとされており特殊な用途に使用されている。 The drum type refiner differs from the first two in that it has a metal operating surface, and is a cylindrical refiner consisting of a stone shell and a rotor, and the blade is formed by cutting a number of grooves into the rotor. Ciel is generally divided into four parts, each with a stone attached to it, each of which can be pressed against a rotor using water pressure. Since the material of the stone is basalt or lava, the refining action is gentler than that of a metal working surface, and it is said to have the characteristic of sufficiently improving the strength of the fibers as there is less cutting or damage to the fibers. . On the other hand, since it is a natural material, it is difficult to obtain a homogeneous material, the material is easily worn out, and there are problems with quality control and maintenance, so it is used for special purposes.

と耐磨耗性が要求される。 Although much knowledge has been obtained regarding the effects of refining on fibers, such as external fibrillation, internal fibrillation, and fiber cutting, there is very little knowledge regarding the refining mechanism. A.J.
Pearson et al. (Paperi ja Puu No. 4a, 241
(1978)), it is thought that the internal cavity of the fiber is crushed by compressive force, and then the refining progresses due to the force that rotates the flattened fiber. Regarding the interaction between the fibers and the operating surface of the refiner,
Emphasis is placed on the interaction between the fibers and the blades, especially the edges of the blades, and the effects of the grooves are only recognized as fiber passages. For example, Goncharov (Bumazh.
Pro. No. 5, 12-14 (1971)) actually measured the pressure applied to the blade by refining unbleached sulfite pulp with a disc ironer, but it was found that It is acknowledged that there is a strong force between them. The pressure at the tip of the blade under optimal refining conditions reaches 35 Kg/cm 2 , which is 13 times greater than the pressure per total contact area of the blade. It is recognized that in this maximum pressure region, fibers are intensively subjected to actions such as defibration, crushing, and cutting. In this way, the mechanical treatment by the blade on the operating surface of the refiner is quite localized, and moreover, the treatment is quite severe in that area. For this reason, the fibers have a strong tendency to be cut, and the material of the blade part is also required to have high strength and abrasion resistance.

て種々検討されている（例えば特公昭47−23321
号公報、特開昭51−109310号公報参照）が、まだ
十分満足いくものとはなつていない。 When fibers are treated with a refiner, the fibers have various shapes and physical properties due to the different shapes of the blades and grooves on the operating surface of the refiner, which greatly affects the properties of the paper product. For this reason, various studies have been conducted on the shapes of the blades and grooves on the operating surface of the refiner (for example, Japanese Patent Publication No. 47-23321
(see Japanese Unexamined Patent Application Publication No. 109310/1983), but it is still not fully satisfactory.

作面が破損するなど、その耐用時間が著しく短い
ものとなりコスト高となる。 It is also known that the material of the disk working surface has a large effect on the morphology of the fibers. For example, the entire operating surface of the refiner has an elastic modulus of approximately 0.7×10 2 to approx.
1.4×10 3 Kg/mm 2 material, especially synthetic resin (Japanese Unexamined Patent Publication No. 117701/1983, U.S. Patent No.
3880368) shows an increase in long fiber content and improvement in pulp quality, but because the material is weak, the working surface of the disk may be damaged due to foreign matter such as metal pieces, and its service life may be shortened. This results in a significantly shorter length and higher cost.
又リフアイナー類による繊維の機械的処理の基
本的な問題点はエネルギー効率が極端に低く、多
大の電力を消費する点である。 A fundamental problem with mechanical treatment of fibers using refiners is that they have extremely low energy efficiency and consume a large amount of power.

耐久性を要求され、更に加工上、保守上の問題点
があるために実用化されていない。 The power required for refining is 200 yen for chemical pulp.
~800KWh/T, but when producing mechanical pulp, it is 1400~1800KWh/T in RMP and 1,400 to 1800KWh/T in TMP.
It reaches over 2000KWh/T. Therefore, energy saving in the refining process is a very important issue for the pulp and paper industry. A related technology is a method in which the blade portion of the operating surface of the refiner is made of a porous material made of sintered metal particles, and the required power is reduced by processing fibers on the operating surface of the refiner (US Pat. No. 3,160,355). (see specification)
However, since it is a blade, it requires great strength and durability, and there are also problems in processing and maintenance, so it has not been put into practical use.
本発明は、上記現状に鑑みてなされたもので、

複雑な流動をするものと推定される。 The present inventors focused on the grooves on the operating surface of the refiner and studied their role in detail. The operating surface of a refiner is generally divided into a pre-crushing (coarse) region, an intermediate (medium-crushing) region, and a peripheral (refining) region in the order of the flow of raw material fibers toward the outer circumference, depending on the shape and arrangement of the blades and grooves. The groove portion occupies a considerable proportion of the operating surface of the refiner, and its function is to serve as a passageway for the fibers undergoing the refining action to exit to the outer periphery of the operating surface of the refiner by the centrifugal force caused by the rotation of the disk or by the pushing pressure of the raw fibers. It is believed that In particular, in double-disc cliff eyeners, the centrifugal force of the raw material fibers on the operating surface is canceled by the action of the disc rotating in the opposite direction.
It is said that fibers move along the grooves, but
It is presumed that the fibers flow in a complicated manner due to the difference in the shape of the refiner operating surface.

ぼすために必要であることが考えられる。 The refining action on the fibers on the operating surface of the refiner is such that the fibers are subjected to compressive force by the opposing blades and the edges of the blades, and the fibers are subjected to shearing force by the opposing blades and the upper surface of the blades, so that the refining progresses. Although it is generally said, according to the experiments of the present inventors, the phenomenon of clogging of fibers in the grooves indicates that not only the action of the blades and the blades, but also the fibers of the grooves of the blades and the opposing operating surface, the grooves. It is thought that the action of the fibers in the grooves on the opposing working surface is also necessary to exert an effective refining action.
