Abstract
The present invention provides a kind of beating mill disk of fiberizer, including abrasive disc and the roll flute on abrasive disc, teeth groove is formed between the roll flute and roll flute, the roll flute is 15-25 degree with the angle of abrasive disc radius, the abrasive disc is divided into Nei Moqu, Zhong Moqu and Wai Moqu from inward flange to outward flange, roll flute between adjacent mill area disconnects, and the teeth groove in each mill area is insertion from the inward flange in the mill area to outward flange.Three Ge Mo areas of abrasive disc play respective effect respectively to slurry, make the defibrination quality of paper pulp more uniform, and conquassation and wire-dividing broom purification effect are more preferable；Strengthen beating effect, increase the throughput of paper pulp, so as to improve overall beating efficiency, reducing power consumption of the fiberizer in pulping process.
Description
Technical field
The present invention relates to pulping technology for paper-making field, and in particular to the beating mill disk of fiberizer in a kind of paper making equipment.
Background technology
Abrasive disc is the core parts of fiberizer in paper industry defibrination workshop section, directly paper pulp fiber is produced the active forces such as shearing, conquassation, stretching, friction to change fibre morphology, meets suitability of manufacturing paper with pulp.Paper pulp is after steaming and decocting or mechanical grinding, screening and bleaching, must also be able to discongest, moderately cut off and wire-dividing broom purification through the fiber during defibrination can just make paper pulp, more importantly fiber absorbs water swollen in beating, it is allowed to higher elasticity and plasticity, meet the requirement of paper machine production, so that the paper of production can reach expected quality index.
True qualities needle slurry is processed using double plate mill series connection beating typically in defibrination workshop section, to guarantee paper machine for slurry needs, abrasive disc adopts big throughput profile of tooth, but as with beating wet stock class abrasive disc, because its throughput it is little, Production requirement can not be met, stock volume can not be still met after increasing throughput, and excessive throughput makes the relative reduction of beating effect that fiber is subject to, beating degree is low, weight in wet base is difficult to be declined, and beating efficiency and quality are not ideal enough.And the shortcomings of refining pulp quality is uneven, effect is poor, power consumption is high is caused using through-type abrasive disc.
The content of the invention
The present invention seeks to solve above-mentioned deficiency, there is provided a kind of beating is uniform, the grinding plate of pulping machine of efficiency high, and has saved power consumption, improves the throughput of paper pulp.
In order to reach the effect above, the present invention provides a kind of beating mill disk of fiberizer, including abrasive disc and the roll flute on abrasive disc, teeth groove is formed between the roll flute and roll flute, the roll flute is 15-25 degree with the angle of abrasive disc radius, the abrasive disc is divided into Nei Moqu, Zhong Moqu and Wai Moqu from inward flange to outward flange, and the roll flute between adjacent mill area disconnects, and the teeth groove in each mill area is insertion from the inward flange in the mill area to outward flange.
The preferred version of such scheme is that the extended line of each roll flute in Nei Moqu, Zhong Moqu and Wai Mo area is misaligned.
The preferred version of such scheme is that the area ratio in Nei Moqu, Zhong Moqu and Wai Mo area is 2: 5: 3.
The beating mill disk of the present invention, abrasive disc are divided into three Ge Mo areas, and Nei Mo areas active area for total contribution area 20% is mainly discongested fiber and improves the slurry pressure into Mo Qu chambers；Zhong Mo areas account for the 50% of total contribution area, act primarily as cutting fibre effect；Wai Mo areas account for the 30% of total contribution area, main to strengthen the brooming effect to fiber；Its total throughput improves more than 10%, hence it is evident that improve the beating uniformity, and beating degree improves 8-10 ° of SR, and weight in wet base drops to appropriate criteria；Make a day beating time save 3 hours or so, slurry guarantee is provided for paper machine.In addition, according to statistics, it is 6 fiberizers by a paper production line, every defibrination acc power is calculated for 90kw, then save electricity is daily：3*90*6*80%=1296kw/h, business efficiency are considerable, and have substantially carried out avoiding apex filling vale power mode.
The present invention is had the benefit that compared with prior art：
1st, the teeth groove increase between roll flute, then increase the throughput of paper pulp, so as to improve overall beating efficiency；
2nd, three Ge Mo areas of abrasive disc play respective effect respectively to slurry, make the defibrination quality of paper pulp more uniform, and conquassation and wire-dividing broom purification effect are more preferable.
3rd, the extended line of the roll flute in three Ge Mo areas is misaligned, then illustrate that roll flute has certain angle of inclination, and on the abrasive disc of same size, its roll flute accordingly increases, then beating effect strengthens, and effectively suppresses the chopped fiber of cut-out paper pulp；
4th, improve production efficiency, reduces power consumption of the fiberizer in pulping process.
5th, illustrate
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural representation of abrasive disc of the present invention；
In figure：1- abrasive discs, 2- roll flutes, 3- teeth groove, A- Nei Mo areas, B- Zhong Mo areas, C- Wai Mo areas.
Specific embodiment
Embodiment one：
As shown in Figure 1, a kind of beating mill disk of fiberizer, including abrasive disc 1 and the roll flute 2 on abrasive disc 1, teeth groove 3 is formed between the roll flute and roll flute, the roll flute is 20 degree with the angle of abrasive disc radius, the abrasive disc is divided into Nei Mo areas A, Zhong Mo area B and Wai Mo areas C from inward flange to outward flange, and the roll flute between adjacent mill area disconnects, and the teeth groove in each mill area is insertion from the inward flange in the mill area to outward flange.The extended line of each roll flute in Nei Mo areas A, Zhong Mo area B and Wai Mo areas C is misaligned, and the area ratio of Nei Mo areas A, Zhong Mo area B and Wai Mo areas C is 2: 5: 3.
Embodiment two：
Identical with one structure of embodiment, it is 24 degree which differs only in roll flute with the angle of abrasive disc radius.
Abrasive disc is divided into three Ge Mo areas by the new beating mill disk of fiberizer, and Nei Mo areas active area for total contribution area 20% is mainly discongested fiber and improves the slurry pressure into Mo Qu chambers；Zhong Mo areas account for the 50% of total contribution area, act primarily as cutting fibre effect；Wai Mo areas account for the 30% of total contribution area, main to strengthen the brooming effect to fiber.Three Ge Mo areas of abrasive disc play respective effect respectively to slurry, make the defibrination quality of paper pulp more uniform, and conquassation and wire-dividing broom purification effect are more preferable.Teeth groove increase between roll flute, then increase the throughput of paper pulp, so as to improve overall beating efficiency；The extended line of the roll flute in three Ge Mo areas is misaligned, then illustrate that roll flute has certain angle of inclination, and on the abrasive disc of same size, its roll flute accordingly increases, then beating effect strengthens, and effectively suppresses the chopped fiber of cut-out paper pulp；And improve production efficiency, reduce power consumption of the fiberizer in pulping process.
Above example is not limited only to protection scope of the present invention, all basic thoughts based on the present invention and modify or change belong to protection scope of the present invention.
