Abstract

The utility model discloses a grinding disc with grooves on grinding gears for beating in a paper making process. The grinding disc is characterized in that: a plurality of parallel grooves are formed on the grinding gears; an included angle alpha between each grinding gear and each groove is more than 0 and less than 90 DEG; and the width of each groove is between 1 and 4mm. The grinding disc is suitable for beating at low concentration, can cut fibers uniformly, and can separate and broom the fibers at the cutting positions to ensure that the fibers are not fractured frequently; and effective grinding areas are increased during beating, and a large amount of energy consumption is reduced.

Description

The papermaking beating mill disk of with groove on a kind of roll flute

Technical field

The utility model relates to beating equipment for paper making, the papermaking beating mill disk of with groove on particularly a kind of roll flute.

Background technology

Disc pulping machine and jordan abrasive disc commonly used; Its beating results is undesirable, particularly when breaking high strength fibre, and suitable beating consistency lower (referring to the low concentration making beating here); Beating degree rises very fast; It is relatively poor that it is cut off with the effect of wire-dividing broom purification, for the paper machine of common cloth slurry system, is difficult to the high-quality paper product of output, like the generation mass defect that evenness is poor, paper is coarse, green deformation is big.When refining pulp quality did not reach preferably effect, the measure of taking was exactly to make up through 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 frequently, causes production cost to rise.

The utility model content

The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of at this and can make the papermaking beating mill disk that fiber well cuts off, wire-dividing broom purification also can cut down the consumption of energy.

The utility model is achieved in that the papermaking beating mill disk of with groove on a kind of roll flute of structure, it is characterized in that: contain many grooves that are parallel to each other on the roll flute, an angle a is arranged, 0＜a＜90 between roll flute and groove ⁰, said groove width 1-4mm.At the abrasive disc roll flute flank of tooth, process many parallel grooves along certain orientation.Groove width 1-4mm is advisable, and is advisable not deposit slurry, makes slurry after getting into the mill district, further shunted by refinement, and is cut off and wire-dividing broom purification by sharp edges on the groove, thereby reach even making beating purpose.

The advantage of the utility model is: the utility model is suitable for the low concentration making beating, can make uniform cut-out of fiber and wire-dividing broom purification and seldom conquassation of fiber, and wire-dividing broom purification all is at cut-off part.Effectively grind the district during making beating and increase considerably, saved mass energy consumption.

Fig. 1 is abrasive disc 1/4 structural representation in the utility model.

Fig. 2 is an abrasive disc partial structurtes enlarged diagram in the utility model.

Fig. 3 is the fiber orientation sketch map.

Among the figure: 1, roll flute, 2, groove, 3, roller seating space.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is made detailed description:

In order to overcome the deficiency of prior art, the utility model provides the papermaking beating mill disk of with groove on a kind of roll flute, and is as shown in the figure: contain many grooves that are parallel to each other 2 on the

roll flute

1,2 of roll flute 1 and grooves have an angle a, 0＜a＜90 ⁰, said groove width 1-4mm is advisable not deposit slurry.

Shown in Fig. 3, during the abrasive disc high-speed rotation, fiber pumps under centrifugal action; A fiber part flows out from roller seating space 3; Another part flows into along groove 2, and the fiber in the roller seating space 3 is cut off by the main tooth edge edge of a knife or divides silk, and the fiber in the groove 2 is by the cut-out of the slot wedge edge of a knife or divide silk; Thereby improved making beating efficient and uniformity coefficient greatly, thereby reached the purpose that reduces beating energy consumption.

Claims

1. the papermaking beating mill disk of with groove on the roll flute is characterized in that: contain many grooves that are parallel to each other (2) on the roll flute (1), an angle a is arranged, 0＜a＜90 between roll flute (1) and groove (2) ⁰, said groove (2) width 1-4mm.
