Abstract

A stator and rotor of refining machine and grinding disc of paper-making beating machine for beating fibres and cutting and fibrillating fibres uniformly is composed of grinding teeth, check ring, grinding disc and fixing screw hole, and features that the included angle between grinding teeth and grinding disc is an inclined angle (alpha is 0-90 deg). The mounting structure is respectively compatible with the grinding disc of a common beater and the stator and the rotor of a refiner. The suitable beating concentration is higher than that of a common grinding plate, the beating degree is relatively slowly increased, the beating energy consumption is low, the service life is long, and the production cost is low.

Description

Papermaking beating mill disk and jordan stator rotor

The utility model relates to beating equipment for paper making, particularly a kind ofly is used for fiber making beating and fiber is cut off and the abrasive disc of wire-dividing broom purification and stator, the rotor of jordan uniformly.

Disc pulping machine and jordan abrasive disc commonly used, its beating results is undesirable, particularly when breaking high strength fibre, suitable beating consistency lower (referring to low consistency pulping here), beating degree rises very fast, it is cut off and the effect of wire-dividing broom purification relatively poor, for the paper machine of common cloth slurry system, be difficult to the high-quality paper product of output, evenness is poor, paper is coarse as producing, the big mass defect of sex change wets.When refining pulp quality did not reach preferably effect, the measure of taking was exactly to make up by increasing the way that the making beating electric current improves the making beating load, in the hope of reaching requirement.Directly cause beating energy consumption to rise but do like this, and even more serious be roll flute wearing and tearing aggravations, the abrasive disc lost of life is changed again and again, causes production cost to rise.

The purpose of this utility model be the design a kind of can make the good cut-out of fiber can make again its better wire-dividing broom purification and can with common beater control and structure on the compatibility the papermaking beating mill disk.

The purpose of this utility model reaches by the following technical programs:

The stator rotor of papermaking beater abrasive disc and jordan mainly partly is made of roll flute, back-up ring, mill, fixing threaded hole, and the angle α that it is characterized in that roll flute and mill is an inclination angle, and angle is between 0～90 °.Because roll flute is inclined, make interlaced formation between every pair of roll flute of two abrasive discs of fast turn-around have the sword seam of the very strong power of cutting effect, when fiber during, be cut off immediately and on the flank of tooth, pressed feedback and wire-dividing broom purification by this sword seam.The mounting structure of beater abrasive disc and jordan stator rotor respectively with common beater abrasive disc and jordan stator, rotor compatibility.

The utility model compared with prior art, its advantage is: suitable beating consistency is higher relatively, beating degree rises relatively slow, and fiber is cut off and wire-dividing broom purification uniformly; In use, its cutting edge plays the effect of sharpening again when the phase attrition is examined, remain sharp state; Beating energy consumption is low, and the life-span is long.Since its mounting structure respectively with stator, the rotor compatibility of the abrasive disc and the jordan of common beater, so wide popularization and application very easily.

Fig. 1 is the disk abrasive disc structural representation in the utility model;

Fig. 2 is that disk abrasive disc A in the utility model is to local enlarged diagram;

Fig. 3 is the disk abrasive disc combination embodiment partial structurtes enlarged diagram in the utility model.

Below in conjunction with accompanying drawing the utility model is further described:

Shown in Fig. 3, during high speed rotating, fiber pumps under centrifugal action moving abrasive disc 4, runs into the back-up ring upset in the counterclockwise direction, is cut off during sword seam by roll flute 1, and is pressed feedback and wire-dividing broom purification at the interplanar of two roll flutes.3 is the stator abrasive disc among Fig. 3, and 2 is mill.

Shown in Fig. 2, the angle α between the plane of roll flute 1 and mill 2 is an inclination angle, and the size of this inclination alpha, the facewidth and tooth depth depend on the throughput of fiberizer or jordan and the requirement of refining pulp quality.

Claims

1, stator, the rotor of a kind of papermaking beater abrasive disc and jordan are made of roll flute, back-up ring, mill, fixing threaded hole, and the angle α that it is characterized in that roll flute and mill is an inclination angle, 0＜α＜90 °.
