The refining disc can prolong the retention time of materials in the disc mill, weaken the cutting function, increase the effects of conquassation, rubbing and fibrillation of fibers, and greatly improve the microfibration degree of pulp fiber.
Description
Technical field
The utility model relates to a kind of pulping equipment, is specifically related to a kind of disc mill mill of suitable preparation high-performance synthetic fiber pulp.
Background technology
In the technology, refining equipment mainly contains the disk mill in form at present, conical disc mill, cylinder mill.Wherein the disc mill of disc abrasive disc is used early, uses more extensive.Disc mill can be divided three classes according to its mill: 1 Moving plate and 1 single disc refiner that price fixing is formed; The double plate mill that the Moving plate of 2 switched in opposite is formed; The triple disc refiner that 2 price fixings and middle 1 Moving plate are formed.In various fiberizers, abrasive disc is the core component of disc mill.Disc mill has been obtained significant effect in various natural fabrics and artificial fibre application.But existing abrasive disc is not suitable for being applied to prepare high-performance synthetic fiber pulp.High-performance fiber has the resistant to elevated temperatures characteristics of high-strength and high-modulus, obtain the high high-performance pulp of specific area, requires disc mill abrasive disc material better, can be durable in use, and the abrasive disc configuration need reduce the cut-out situation of fiber, increase fiber fibrillation degree as far as possible.Existing abrasive disc can not well satisfy this requirement.
For example, Chinese patent application number " 200910192235.4 " discloses a kind of abrasive disc and manufacture method thereof that is used for disc mill, its applying date is on September 11st, 2009, open day is on February 24th, 2010, its abrasive disc comprises roll flute and the abrasive disc matrix through the machine-shaping of twice difference, central shaft around the abrasive disc matrix, it is evenly distributed on the abrasive disc matrix that roll flute is a plurality of concentrically ringed states, be provided with baffle between each roll flute, each baffle that is positioned on the same circle forms spiral helicine retaining slurry line at the abrasive disc matrix surface; The manufacture method of abrasive disc is to make the required roll flute of abrasive disc earlier and carry out surface treatment, then according to the abrasive disc form processing mould that designs, each roll flute and baffle are installed on the mould back casts in the mould that installs roll flute or vulcanizes, in the time of moulding abrasive disc matrix roll flute is fixed on the abrasive disc matrix, promptly finishes making behind the cooling withdrawing pattern.The problem that adopts above-mentioned abrasive disc to exist is: one, the corner angle of roll flute are the right angle, and roll flute causes stronger cutting action to fiber when mill is worked, and influences the pulp quality.Two, roll flute and abrasive disc matrix machine-shaping respectively is welded to roll flute on the matrix again, the manufacturing technique complexity, and easy tooth-breaking, service life is short.
For another example, China Patent No. " 200510032283.9 " discloses a kind of mill that is used for fiberizer, this mill comprises the rotary grinding disk that is installed on the fiberizer main shaft and is installed on the interior fixed millstone that matches with rotary grinding disk of fiberizer housing, be provided with concentric circles retaining dam in the teeth groove of described rotary grinding disk and fixed millstone, be between a round shear zone between per two concentric circles retaining dam, the concentric circles that every mill is provided with more than 4 comes and goes between the shear zone, the concentric circles retaining dam of rotary grinding disk and fixed millstone alternately shifts to install, cut the interval for simple shear between the concentric circles retaining dam that adjoins mutually after two mills shift to install, tooth depth and simple shear are cut and interval widely all strengthened with radius and diminish gradually, the gullet base of the first lap roll flute in the close center of circle is that the abrupt slope is skewed on the described rotary grinding disk, its stock inlet place tooth depth maximum, the straight first lap concentric circles of going up that tilts keeps off the following place of dam tooth top, and profile of tooth is positive profile of tooth.The problem that adopts above-mentioned mill to exist is: one, the profile of tooth of its roll flute is positive profile of tooth, and fiber is caused stronger cutting action, influences the pulp quality.Two, the concentric circles of rotary grinding disk and fixed millstone retaining dam alternately shifts to install, and causes material passing through easily between the shear zone under the mill centrifugal action, has reduced the time of staying of slip in mill, is unfavorable for the abundant fibrillation of fiber.
Summary of the invention
