Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further detail.
As it is shown in figure 1, a kind of flat-taper grinding disc of high consistency refining machine structure, including can mutually overlap
The static cutting disk 1 connect and movable grinding disc 2, described static cutting disk 1 includes that the static cutting disk of its lower circumference is thick
The static cutting disk fine grinding district 4 of mill district 3 and upper circumference, described static cutting disk corase grind district 3 and static cutting disk
Fine grinding district 4 is surrounded by eight abrasive disc unit 5 respectively；
As in figure 2 it is shown, movable grinding disc 2 is made up of fracture area, corase grind district and fine grinding district, guiding gutter
The adjacent abrasive disc of two panels forms diversion groove 9.Fracture area and groove gradient thick, fine grinding district are
15 °, mill, when rotating, produces pumping effect to material, because the fracture area roll flute facewidth is wider,
Spacing is relatively big, and the pumpability therefore produced is higher, material via guiding gutter quickly to corase grind district
With the flowing of fine grinding district, and the discharge of beneficially steam.
Described movable grinding disc 2 includes barrel 11, and barrel 11 is provided with spacing ring 15, institute
Vertically-mounted at the bottom of barrel 11 interior barrel stated have main shaft 17, is provided with support on main shaft 17
Frame 16 is also connected with spacing ring 15；Described spacing ring 15 is divided into outside barrel 11
Circumference up and down, the lower circumference at barrel 11 is corase grind district, described corase grind district is provided with thick
Mill district abrasive disc 7, the upper circumference at barrel 11 is fine grinding district, and described fine grinding district is provided with
Fine grinding district abrasive disc 8；Lower guiding gutter, fine grinding district abrasive disc is formed between described corase grind district abrasive disc 7
Between 8, formation above guiding gutter, upper guiding gutter and lower guiding gutter are on same vertical curve, upper water conservancy diversion
Groove forms diversion groove 9 with lower guiding gutter；Fracture area mill is installed bottom described barrel 11
Sheet 6.
Described fracture area abrasive disc 6, corase grind district abrasive disc 7 pass through spiral shell respectively with fine grinding district abrasive disc 8
Bolt 1, bolt 2 13 and bolt 3 12 are arranged on barrel 11.
As it is shown on figure 3, fracture area abrasive disc 6 is fixed on barrel 11 by fracture area bolt 1
On, when changing fracture area abrasive disc, only need to pull down fixing bolt, change abrasive disc.Corase grind district
Corase grind district abrasive disc 7 is fixed on barrel 11 by bolt 2 13, when changing corase grind district's abrasive disc 7,
Only need to pull down fixing bolt, change abrasive disc.Fine grinding district bolt 3 12 will fine grinding district abrasive disc
8 are fixed on barrel 11, when changing fine grinding district's abrasive disc, only need to pull down fixing bolt, change
Abrasive disc.
As shown in Figure 4, spacing ring 15 is divided into four, is fitted around outside barrel 11, uses
In limiting corase grind district abrasive disc 7 and fine grinding district abrasive disc 8 owing to being carried by the impact of axial force and steam
Lotus is produced to slide, and increases the integral rigidity of movable grinding disc 2.
As it is shown in figure 5, bracing frame 16 is installed on main shaft 17 and coordinates with spacing ring 15,
Spacing ring 15 is fixed on outside cylinder 11 by caging bolt 18, and bracing frame 16 passes through bolt
It is fixed on inside cylinder 11, plays and support cylinder and increase the effect of cylinder rigidity.
The operation principle of the present invention:
Paper pulp enters fiberizer fracture area from conical refiner front end (small end), and paper pulp is at a high speed
The movable grinding disc 2 rotated drives lower generation peripheral linear speed and radial centrifugal force.Owing to cone turns
Son makes the peripheral linear speed of rear end (end greatly) and centrifugal force bigger than small end, and this mill knot
The pump action that the fracture area of structure, corase grind district and the fine grinding profile of tooth in district, tine angle produce, causes
The static pressure ratio small end of end is little greatly, and under " constraint " and guiding of roll flute, paper pulp has by little
Hold to the big trend holding movement.The mill chamber that slurry once enters movable grinding disc 2, static cutting disk 1 is formed,
By the mechanicals efforts of roll flute between rotor and stator, produce making beating effect.In pulping process
The steam produced is discharged by the diversion groove 9 on this movable grinding disc, steam the axial impact produced
Mainly undertaken with spoke shape bracing frame 16 by spacing ring 15.
