Detailed description of the invention
In order to make content of the present invention more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation.
As shown in figures 1-6, column type paper-making paste mill combination abrasive disc of the present invention, the rotor abrasive disc 1 comprising some and the stator abrasive disc coordinated with it, rotor abrasive disc 1 quantity is 4 or 6, and stator abrasive disc is identical with rotor abrasive disc quantity.Every sheet abrasive disc comprises fine grinding district 2 and inlet region 3, and precise abrasive plate 2 comprises roll flute 4 and groove 5, and roll flute 4 coordinates by a certain percentage with the width of groove 5.Roll flute 4 shape is generally straight-tooth, inlet region 3 also comprises roll flute 6 and groove, wherein roll flute 6 is arc-shaped gear or bending tooth, its rear end is in smoothing junction with the roll flute 4 in fine grinding district 2, its front end crest top land is in smoothing junction with the base portion 7 of certain angle and its place abrasive disc, and general angle is that 20 ° ~ 60 ° suitable angles get 30 ° ~ 45 °;
Abrasive disc base portion 7 is matrixes of abrasive disc, and roll flute 4 and 6 and teeth groove thereof are formed on matrix by casting or the means such as machining or welding.
The roll flute 4 in fine grinding district 2 also can select bending tooth or arc-shaped gear, and arc or bending roll flute have better end specific pressure and refining effect than straight roll flute; And the front end crest top land of the roll flute 6 of the inlet region 3 of rotor, stator abrasive disc can be parallel be connected with abrasive disc base portion 7, if the A in accompanying drawing 2 is to enlarged diagram;
The bus of abrasive disc is the projection of axis on this abrasive disc lateral surface of column type paper-making paste mill.The entrance angle α of roll flute 4 in fine grinding district 2 be identical with runner direction of rotation, extend the angle formed to the port of export and this abrasive disc bus from fiberizer arrival end, value is 0 ° ~ 60 °, and optimum value is 15 ° ~ 45 °.The effect mainly pumping slurry of entrance angle α, controls the holdup time of slurry between abrasive disc and the frequency of defibrination.The entrance angle α ＇ of the roll flute 6 of inlet region 3 angle that to be roll flute 6 formed by the tangent line of the roll flute inner circle of the bending of fiberizer entrance end points or arc and this abrasive disc bus, its value is greater than entrance angle α, but maximum is not more than 90 °, the entrance angle α ＇ that the roll flute 6 of inlet region 3 is formed makes with the angle larger than entrance angle α that slurry is easier sooner enters fine grinding district 2, decrease the disturbance of slurry outside inlet region 3 and holdup time, improve the end specific pressure in fine grinding district 2, thicken fiber mat, improve defibrination quality, extend abrasive disc service life.The rear end of the roll flute 6 of inlet region 3 and the connection rounding off of the roll flute 4 in fine grinding district 2, the cut to lengthen of the roll flute 6 of inlet region 3 is within 80mm.
The arc of the inlet region 3 of column type paper-making paste mill combination abrasive disc of the present invention or bending roll flute 6, function class is similar to the blade in pump.Aqueous slurry enters the passage of the cylindrical, hollow of fiberizer under the effect of steam together with water at feeding screw, reach the object of finish milling slurry by getting rid of the slurry valve gap entered between rotor and stator.The thrust pumping slurry that the roll flute 4 in the fine grinding district 2 of rotor abrasive disc is formed with the certain entrance angle α formed with abrasive disc bus is to refining district 2 end feed, the arc of inlet region 3 or bending roll flute 6 make slurry faster with larger entrance angle α ＇, easier entering refines district 2, decrease the disturbance of slurry at inlet region 3 place and holdup time, improve fine grinding district 2 end specific pressure, fiber mat thickens, defibrination quality can be improved, extend abrasive disc service life, and the roll flute 4 in the fine grinding district 2 of stator abrasive disc has been detained slurry with contrary entrance angle simultaneously, make slurry by abundant grinding.
Column type paper-making paste mill combination abrasive disc of the present invention, its front end of roll flute one by one 6 of inlet region 3 is connected with arrival end abrasive disc base portion 7, or several roll flutes 6 are connected with the abrasive disc base portion 7 of inlet region 3 in groups.When roll flute 6 is connected with abrasive disc base portion 7 one by one, the cutting into position of every bar roll flute 6 is the same, and its throughput and born pressure are also the same; Such as, or can be connected with the abrasive disc base portion 7 of entrance 3 in groups by several roll flutes 6: 2,3,4,5, each group is all or part of flush parallel or be similar to flush parallel.Flush parallel or be similar to flush and several roll flutes 6 of behavior and base portion 7 link position perpendicular to be similar to perpendicular to or at an angle in the straight roll flute 4 or the roll flute 6 that refine district 2.Except closest to except the roll flute 6 of inlet region 3, follow flush other parallel roll flute not to be connected with abrasive disc base portion 7, and the open position be not connected with the base portion 7 of abrasive disc inlet region 3 forms inlet slurry stagnant area 8, inlet slurry stagnant area 8 makes the slurry outside abrasive disc base portion 7 enter more rapidly abrasive disc inlet region 3, up-to-date distribution slurry enters between roll flute again, is convenient to shorten the time that slurry enters abrasive disc fine grinding district 2.
Several roll flutes 6 in groups time, wherein at least one is arc or bending roll flute closest to inlet region 3, or simultaneously two or three, can also can spacedly walk abreast side by side, also can be that arc or bending roll flute and straight-tooth are alternately arranged, as several connected modes of accompanying drawing 6A, B, certainly also have other connected mode, those skilled in the art can be summarized by above-mentioned disclosed connected mode and obtain, and are not described in detail in this.
Above-described specific embodiment; object of the present invention, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
