The specific grinding process is as follows: starting the motor 5, the motor 5 drives the output shaft 6 to rotate clockwise through the rotating shaft, and the output shaft 6 drives the grinding disc 4 to rotate. The top cover 1501 is opened, the PTA coarse material filter cake is fed from the feed inlet 1504, the hammer of the grinding hammer 3 swings from the inside to the outside under the rotation action of the grinding disc 4 and the centrifugal force, and swings to be in contact with the grinding drum 2, the PTA coarse material filter cake entering the grinding device 15 is extruded and ground, and the qualified PTA coarse material filter cake falls from the blanking hole 201 and between the first toothed ring and the second toothed ring through the guide plate 10, and is discharged from the discharge port 1502 into the inner cavity of the reaction kettle body 1.
When the grinding hammer 3 is stuck by the PTA coarse material cake, the speed is reduced, the PTA coarse material cake pushes the grinding hammer 3 to move backward relative to the support shaft 14, so that the ratchet 301 is disengaged from the pawl 11, the grinding hammer 3 swings back under the action of the torsion spring 304 to avoid the stuck material, the grinding hammer 3 is unlocked, and the torsion spring 304 urges the grinding hammer 3 to be in the initial sliding position on the support shaft 14.
When the motor 5 stops working, the speed of the grinding disc 4 is suddenly reduced, the grinding hammer 3 slides forwards along the supporting shaft 14 under the influence of inertia, the pressing head 121 and the stopping head 122 are pushed downwards, the pressing head 121 and the stopping head 122 drive the locking ring 7 and the pawl 11 to move downwards, the ratchet 301 and the ratchet wheel are disengaged, the locking ring 7 simultaneously presses the return spring 406 to move downwards, the two stopping claws of the stopping head 122 are matched with the sliding block 804, the sliding block 804 is pushed to compress the arc-shaped spring 801 along the guide ring 802, so that the grinding disc 4 is rapidly stopped, the centrifugal force of the grinding hammer 3 is rapidly reduced, the hammer part of the grinding hammer 3 swings inwards under the action of the torsion spring 304 and is lapped above the limit table 403. The grinding hammer 3 is restored to the original position, and the lock ring 7 is moved up by the urging of the return spring 406, so that the locker 12 and the pawl 11 are restored.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
