Description
Technical field
The utility model relates to the beating equipment for paper making in a kind of paper making equipment technical field, particularly a kind of abrasive disc of papermaking defibrination.
Background technology
In paper industry, grinding plate of pulping machine is the paper pulp fiber utilizing the process of abrasive disc groove mechanism to suspend in water, and makes it have adaptation and produces required characteristic on a papermaking machine, and makes produced paper can reach a kind of part of prospective quality operation.Fiberizer generally has two secondary abrasive discs, and a pair is Moving plate, drives do circumference rotation with motor, and another pair maintains static or do to rotate in the other direction, and the roll flute of two secondary abrasive discs is tangent in the plane, forms several " scissors ".People often select when choosing fiberizer that defibrination speed is fast, noise is little, the machine that life-span is long, energy consumption is low, abrasive disc is then most important parts in fiberizer, belong to consumable accessory, therefore unexpected except requiring that abrasive disc has good refining effect on producing, also require that abrasive disc must have the mechanical tenacity of good anti-wear performance and opposing certain impact load, require that abrasive disc must have longer service life simultaneously, keep pulp quality in production steady in a long-term and the object reducing pulping quality fluctuation to reach.
Conventional disc pulping machine and jordan abrasive disc, its beating results is undesirable, particularly when breaking high strength fibre, suitable beating consistency lower (referring to that low concentration is pulled an oar here), beating degree rises very fast, make it cut off with the effect of wire-dividing broom purification poor, for common cloth slurry system paper machine be difficult to the high-quality paper product of output, as produced the mass defect that evenness is poor, paper is coarse, green deformation is large.When refining pulp quality does not reach good effect, the measure taked is exactly that the way improving making beating load by increasing making beating electric current is made up, to reaching requirement.But do like this and directly cause beating energy consumption to rise, and more seriously roll flute wearing and tearing aggravation, the silent film lost of life, changes frequent, causes production cost to rise.In needing in the manufacture of high-strength box paperboard, high consistency refining is to better intensity and adhesion after realizing defibrination, but the existing abrasive disc kind of selecting of middle high consistency refining is few, and be all generally often carry out defibrination with reference to the structure of low dense abrasive disc or directly adopt original low dense abrasive disc defibrination simply, fiber entanglement degree is high, refining effect is poor.
The profile design of abrasive disc determines according to the characteristic of the qualitative requirement and fiber itself that will produce paper, instead of machine-made approved product.The shape of desirable synthesis fibrid is a kind of synthetic fiber in spider shape, and in the process of manufacturing paper with pulp of paper, wish that the wire-dividing broom purification of fiber wants good, the effect of fine fibre is wanted obviously, and the length of fiber will be grown simultaneously.
In actual production, the key factor affecting refining effect long-term stability is the roll flute quality of abrasive disc in fact, and the factor determining beating results is the degree of depth of the inclination angle of the width of the tooth of abrasive disc, tooth, groove, width and in the trench with or without baffle plate mainly.Roll flute is as the stressed member of abrasive disc, and the length in its life-span determines the life-span length of whole abrasive disc.The ubiquitous shortcoming of existing abrasive disc is that service life is short, and frangible easy fracture often need be dismantled, thus have impact on production efficiency.
Chinese patent CN202530332 discloses a kind of paper-making paste mill abrasive disc, abrasive disc is formed by monoblock type disk or by the combination of polylith fanning strip, roll flute is spaced apart is from inside to outside divided into fracture area, corase grind district, fine grinding district and fine grinding Ge Huan district of district four, relative flute position by inner ring district to outer zone in density step by step, roll flute becomes 55o-65o inclination angle with base plate basal plane.This utility model roll flute is longer to fibre length, and the fibre cutting being difficult to cut off of deflection and good toughness is made good use of, and effect is high, significantly improves for beating bamboo pulp output, and abrasive disc uses greatly improve service time, and reduces pulp beating power.
Chinese patent CN202766899 discloses a kind of abrasive disc for papermaking, is provided with multiple mill district, and multiple mill district is along the edge equidistant even setting successively of papermaking mill; Each mill district is provided with two teeth portion, be specially the first teeth portion and the second teeth portion, first teeth portion comprises many roll flutes be parallel to each other, second teeth portion comprises many two roll flutes be parallel to each other, one end of two roll flutes connects with the side in the first mill portion, and the angle of a roll flute place straight line and two roll flute place straight lines is 10 ° ~ 50 °.Compared with prior art, this utility model is improved for the angle of the roll flute of abrasive disc for papermaking, improve abrasive disc for papermaking to the ability of discongesting of fiber, improve fibrous binding force and to be beneficial to paper shaping.
Chinese patent CN202766900 discloses a kind of papermaking disc mill abrasive disc, and it is provided with multiple mill district, and mill district is provided with many protruding roll flutes, be arranged in parallel, and the gap between roll flute is 0.1mm between roll flute.Compared with prior art, gap between the roll flute of this utility model is set to 0.05 ~ 0.2mm, is conducive to improving that abrasive disc for papermaking improves fiber when defibrination discongests degree, improves the binding ability between fiber, thus be conducive to the shaping of paper, improve the intensity of paper.
German patent DE 202005007551U1 also discloses a kind of papermaking disc mill abrasive disc, and this abrasive disc is provided with roll flute and groove, can be used for papermaking defibrination.
But above-mentioned patent does not all relate to the roll flute width problem of the abrasive disc of papermaking defibrination, roll flute is as the stressed member of abrasive disc, and the length in its life-span determines the life-span length of whole abrasive disc.The operationally suffered load of the shorter roll flute of length is larger, and more frangible easy fracture, causes the ubiquitous shortcoming of existing abrasive disc to be that service life is short, often need dismantle, thus have impact on production efficiency.
