Specific embodiment
The present invention is specifically described with reference to the accompanying drawing, as shown in Figs. 1-5, in the present embodiment:
Firstly, mount a device onto hydrabrusher, will connection short axle respectively with the grinding device in hydrabrusher
It is connected with driving device, when driving device operation, the connection short axle of lower section starts rotation and crushing shaft is driven to start to rotate, under
The crushing shaft rotation of side drives large bevel gear two to start to rotate, and the rotation of gear wheel two drives cone pinion to start to rotate, umbellule
Gear rotation drives large bevel gear to rotate at the beginning, and the rotation of large bevel gear one drives the crushing shaft of top to start to rotate, top
Crushing shaft drive the connection shaft of top to start to rotate, the grinding device in the connection shaft of top drive hydrabrusher
Start to crush the paper pulp in hydrabrusher；
After paper pulp is pulverized, leaked into device by the slurry leakage hole on the crescent screen plate in upper circular groove, simultaneously because
The crushing shaft rotation of top drives rotor segment to start to rotate, and rotor segment rotation will pass through the crescent screen plate in upper circular groove
On slurry leakage hole bleeder in paper pulp crushed again, smashed paper pulp is started by the rotary force of rotor segment
It is rotated in device；
The crushing shaft rotation of lower section drives Disintegrating knife rotation simultaneously, and Disintegrating knife rotation carries out the paper pulp in device
Crush three times, while paper pulp is driven paper pulp to start to rotate by the rotary force of Disintegrating knife, paper pulp simultaneously by rotor segment and
The rotary force of Disintegrating knife, since the steering of two strands of rotary forces is on the contrary, the stress friction for generating paper pulp by rotary force, by paper
Slurry carries out four crushing, and then smashed paper pulp is leaked under sieve plate by the slurry leakage hole on the crescent screen plate in lower circular groove
Side is discharged from the outlet of hydrabrusher.
During aforesaid operations, when paper pulp is by the slurry leakage hole of top, the residual fiber architecture in paper pulp because by
Quickly scraping for rotor segment is disconnected, crushes the fibre structure in paper pulp, while paper pulp carries out wheat-middlings again by Disintegrating knife
It is broken, then so that paper pulp is adequately crushed by two-way rotary force, the time of crushing is saved, while the fiber in paper pulp
Structure sufficiently crushes, and paper pulp is made not block slurry leakage hole.
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.
