Specific embodiment
The present invention is specifically described with reference to the accompanying drawing, as shown in Figs. 1-5:
In the present embodiment, slurry is put by feed inlet 7 in the stir chamber 4 of tank body 1, starts stirring motor by controller 9
11, stirring motor 11 by shaft coupling 12 drive agitating shaft 13 rotate, stirring blade 16 with the rotation of agitating shaft 13 and and slurry
Contact, stirring blade 16 stir slurry and are broken up, and make its fiber separation, and scraper plate 41 is rotated with the rotation of agitating shaft 13,
Scraper plate 41 scrapes the slurry being deposited in first partition 2, rises to the slurry of precipitating at stirring blade 16 and receives stirring again,
Stirring blade 16 drives brush plate 39 to rotate, and the bristle on brush plate 39 is by under the paper pulp brush adhered on 4 inner wall of stir chamber, under brush
Paper pulp receive the stirring of stirring blade 16 again, after stirring a period of time, paper pulp completes pulping process in stir chamber 4, needs
The grinding process of next step is carried out, disperses paper pulp more uniform.
When carrying out grinding process, solenoid valve 34 is first opened, feeder pipe 33 is connected stir chamber 4 and grinding chamber 5 by solenoid valve 34
Access open, the paper pulp of stir chamber 4 is passed through in the grinding groove 21 of lower abrasive disk 20 by feeder pipe 33,13 lower end of agitating shaft with subtract
Fast device 18 connects, and agitating shaft 13 drives retarder 18 to rotate, and retarder 18 drives top lap 19 to rotate, and top lap 19 is being ground
Low speed rotation in slot grinding 21, slurry are fallen on second partition 3 after being fully ground refinement by tooth lapping 36 in grinding groove 21, then
It is flowed out by discharge port 8, when needing pulp mill to obtain more refinement, milling gap, the telescopic end of bilateral servo cylinder 32 can be reduced
Certain length is stretched out, 29 stress of first crossbar pushes the first hinge bar 28, and 28 lower end of the first hinge bar is hinged on 1 bottom of tank body only
It can wave, the first hinge bar 28 transfers force on first sliding block 26 of the upper end, and 26 stress of the first sliding block is sliding on slide bar 25
Dynamic, the inclination angle of the first hinge bar 28 increases and its vertical height increases, and similarly, the second hinge bar 30 is synchronous with the first hinge bar 28
Movement, to make to go up and down the rising of push plate 22, push rod 23 steadily rises in linear bearing 24 with the rising of lifting push plate 22, pushes away
Bar 23 pushes lower abrasive disk 20 to rise, and reduces lower abrasive disk 20 and the gap of top lap 19, so that thinner paper be ground
Slurry need to only control the contraction of bilateral servo cylinder 32, lower abrasive disk 20 can be made to decline when needing to increase milling gap, thus
Increase milling gap.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art
The principle of the present invention is embodied to some variations that some of them part may be made, belongs to the scope of protection of the present invention it
It is interior.
