Specific embodiment
In order that present disclosure is easier to be clearly understood, it is right below according to specific embodiment and with reference to accompanying drawing
The present invention is described in further detail.
As shown in figures 1-6, column type paper-making paste mill combination grinding of the present invention, including a number of rotor grinding 1
And matched stator grinding, it is 4 or 6 that rotor is ground 1 quantity, and stator grinding is identical with rotor grinding quantity.Often
Piece grinding includes refining area 2 and inlet region 3, and refining area 2 includes roll flute 4 and groove 5, and roll flute 4 is compared with the width of groove 5 as certain
Example coordinates.The shape of roll flute 4 is generally straight-tooth, and inlet region 3 also includes roll flute 6 and groove, and 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 area 2, the base portion 7 that its front end crest top land is ground with its place at an angle
Smooth connection, general angle takes 30 °~45 ° for 20 °~60 ° suitable angles；
Grinding base portion 7 is the matrix of grinding, and roll flute 4 and 6 and its teeth groove are by casting or the means such as machining or welding
Formed on matrix.
The roll flute 4 in fine grinding area 2 can also be selected and bend tooth or arc-shaped gear, and arc or the roll flute of bending have than straight roll flute
Preferably end is than pressure and refining effect；And the front end crest top land of the roll flute 6 of the inlet region 3 of rotor, stator grinding can be with parallel
It is connected with grinding base portion 7, such as the A in accompanying drawing 2 is to enlarged diagram；
The bus of grinding is projection of the axis of column type paper-making paste mill on the grinding lateral surface.Refine the mill in area 2
The entrance angle α of tooth 4 is identical with runner direction of rotation, the port of export is extended to from fiberizer arrival end and the grinding bus
The angle of formation, value is 0 °~60 °, and optimum value is 15 °~45 °.The effect of entrance angle α is mainly pumping slurry, control slurry
Expect the frequency of the holdup time and defibrination between grinding.The entrance angle α ＇ of the roll flute 6 of inlet region 3 are entered for roll flute 6 by fiberizer
The angle that the tangent line of the roll flute inner circle of the bending or arc of mouth end points is formed with the grinding bus, its value is more than entrance angle α, but most
Big value is not more than 90 °, and the entrance angle α ＇ that the roll flute 6 of inlet region 3 is formed make slurry faster more hold with the angle bigger than entrance angle α
Easy enters fine grinding area 2, reduces disturbance and holdup time of the slurry outside inlet region 3, improves the end in fine grinding area 2 than pressure,
Fiber mat has been thickened, defibrination quality has been improve, grinding service life has been extended.The rear end of the roll flute 6 of inlet region 3 and fine grinding area 2
Roll flute 4 connection rounding off, the length of the roll flute 6 of inlet region 3 controlled within 80mm.
The arc or bending roll flute 6 of the inlet region 3 of column type paper-making paste mill combination grinding of the present invention, are functionally similar to pump
In blade.Aqueous slurry enters the logical of the cylindrical, hollow of fiberizer in the presence of feeding screw and steam together with water
Road, the purpose of finish milling slurry is reached by getting rid of slurry valve into the gap between rotor and stator.The roll flute in the fine grinding area 2 of rotor grinding
4 thrusts formed with the certain entrance angle α formed with grinding bus pump slurry to the fine grinding end feed of area 2, inlet region 3
Arc or the roll flute of bending 6 with bigger entrance angle α ＇ make slurry faster, it is easier enter fine grinding area 2, reduce slurry and exist
Disturbance and holdup time at inlet region 3, improve the fine grinding end of area 2 than pressure, and fiber mat is thickened, and defibrination quality can be carried
Height, extension grinding service life, and the roll flute 4 in the fine grinding area 2 of stator grinding simultaneously has been detained slurry with opposite entrance angle, makes
Slurry is by abundant grinding.
Column type paper-making paste mill combination grinding of the present invention, its front end of the roll flute one by one 6 of inlet region 3 is ground base with arrival end
Portion 7 connects, or several roll flutes 6 are connected with the grinding base portion 7 of inlet region 3 in groups.When roll flute 6 is connected with grinding base portion 7 one by one
When, the cutting into position of every roll flute 6 is the same, as its throughput is also with the pressure for being born；Or can be with several
Roll flute 6 is connected with the grinding base portion 7 of entrance 3 in groups, for example：2,3,4,5, each group all or
Part is flush parallel or it is flush parallel to be similar to.It is flush parallel or be similar to several roll flutes 6 of flush and behavior and the connection position of base portion 7
Put perpendicular to or be similar to perpendicular to or at an angle in fine grinding area 2 straight roll flute 4 or roll flute 6.Except closest to inlet region 3
Roll flute 6 outside, follow flush other parallel roll flutes not have and be connected with grinding base portion 7, without the base with grinding inlet region 3
The open position of the connection of portion 7 forms inlet slurry stagnant area 8, and inlet slurry stagnant area 8 makes the slurry outside grinding base portion 7 rapider
Into grinding inlet region 3, then it is newest distribution slurry enter roll flute between, be easy to shorten slurry enter grinding fine grinding area 2 time.
Several roll flutes 6 in groups when, wherein at least one closest to inlet region 3 be arc or the roll flute of bending, or simultaneously
Two or three, can side by side can also spaced parallel, or arc or the roll flute of bending with
Straight-tooth is alternately arranged, such as several connected modes of accompanying drawing 6A, B, and certainly also other connected modes, those skilled in the art are led to
Cross connected mode disclosed above and can summarize and obtain, will not be described in detail herein.
Particular embodiments described above, has been carried out further in detail to the purpose of the present invention, technical scheme and beneficial effect
Describe in detail bright, should be understood that and the foregoing is only specific embodiment of the invention, be not intended to limit the invention, it is all
Within the spirit and principles in the present invention, any modification, equivalent substitution and improvements done etc., should be included in guarantor of the invention
Within the scope of shield.
