Description
Affiliated field
The utility model relates to the half stuff treatment facility in the field of papermaking, particularly is used for the cutter that the long stuff making beating is handled in the half stuff treatment facility.
Background technology
In the paper-making pulping process, need to use half stuff equipment, referring to shown in Figure 1, be the fundamental diagram of half stuff equipment.Slurry is put in the stock tank by feeding carriage, pass through cutter, for example hold in the palm the rotation of those many fly cuttves, slurry is circulated in stock tank, and near fly cutter, stationary knife, by the gap of fly cutter, stationary knife, the return pipe of flowing through returns in the stock tank some slurry by " suction ", the circulation that does not stop like this makes slurry all be discongested, cut off when the gap by stationary knife, fly cutter.This half stuff equipment adopts permanent power to be controlled at and guarantees the uniformity of that multitool of holder to the slurry effect.
In order to make the paper of special papery, the three grades of cottons and the cotton linter of need be to three grades of cottons or mixing be mutually handled, but present half stuff equipment can not adapt to three grades of cottons or the three grades of cottons mixing mutually and the processing of cotton linter, being particularly useful for fibre length is the processing of the above slurry of 20mm, exist and handle the slurry overlong time, slurry stops up, shortcomings such as the slurry expansion difference after the processing.Mainly being of these shortcomings:
1, because fibre length increases, is difficult for gap, causes the be commissioned stirring action of that many rotors cutter of slurry, in stock tank, be wound in huge " a slurry group ", influenced normally discongesting of slurry by original equipment rotor cutter;
2, because the raising of fibre strength and length, existing equipment is handled three grades when cotton, and the flowability of slurry is poor, and the time ratio of processing has prolonged nearly one times when handling short flannel, the influence balanced production;
3, owing to the raising of fibre strength and length, slurry is easy to twine behind that many rotors knife back of holder.
4, because the cutter tooth of stator cutter and rotor cutter is upright straight-tooth, the collision between two cutters tooth is the forward collision, and is very big to the damage of cutter tooth.
Cause the reason of these shortcomings to be that the cutter structure of existing half stuff equipment is unreasonable.In the existing cutter structure, the cutter tooth of stator cutter and rotor cutter all is upright straight-tooth, the cutter tooth of stator cutter or rotor cutter and cutter shaft between angle be 0 °, promptly do not have the oblique angle, the structural representation of oblique angle θ as shown in Figure 4; And the cutter tooth of stator cutter or rotor cutter and tool surface tangent plane is 90 °, does not promptly have the inclination angle, and the structural representation of inclination alpha as shown in Figure 5.
Think that on traditional theory the angle between the cutter tooth of the cutter tooth of stator cutter and rotor cutter is 0 °, when promptly not having the oblique angle also not have the inclination angle, the shearing force maximum between two cutters tooth, the intensity of cutter structure are best.But in fact, since the stator cutter with the rotor cutter in the whole axial space of sealing that formed, the straight knife tooth of the vertical type of stator cutter and rotor cutter particularly, formed " wall " together, as Fig. 6 and shown in Figure 8, can not effectively pulp fiber be cut off, simultaneously slurry is passed through preferably, reduced the flowability of slurry, made the slurry layer thickening between stator cutter and the rotor cutter, when especially handling long stuff, because fiber is longer, fiber is difficult for forming bigger fibre bundle, fibrous mass by causing fiber to twine mutually, has weakened shear action on the contrary.
Because the wrong understanding of traditional theory, making the angle of the cutter tooth of the cutter tooth of stator cutter and rotor cutter be 0 ° in the structure of existing cutter overlaps, as Fig. 6 and shown in Figure 8, thereby cause unreasonable, therefore, existing half stuff equipment is not applicable to the slurry processing of three grades of cottons, and a kind of cutter that the long stuff making beating is handled that is used for need be provided.
Summary of the invention
The purpose of this utility model is to provide a kind of cutter that the long stuff making beating is handled that is used for, and this cutter can overcome shortcoming of the prior art, overcomes the part shortcoming at least or alleviates these shortcomings, to improve the slurry of three grades of cottons is handled.
The further purpose of the utility model is, improves the long stapled shear effect of cutter to slurry.
The utility model further another purpose is, improves the flowability of slurry when making beating is handled.
The utility model further another purpose is, improves the problem that slurry twines behind the rotor knife back, improves the trafficability characteristic of slurry.
