The working process and principle related to the whole content of the embodiment are as follows:
when a worker needs to recycle the lithium precipitation mother liquor, the lithium precipitation mother liquor is poured into the precipitation tank 1, then a certain medicament is added and mixed with the lithium precipitation mother liquor, so that part of impurities of the lithium precipitation mother liquor float on the surface, when the surface of the lithium precipitation mother liquor floats too much, the worker opens the air cylinder 501 to drive the piston rod 502 to slide out of the air cylinder 501, the movable frame 503 is pushed to slide on the upper end face of the mounting frame 2, rack plates 511 connected with two sides of the upper end face of the movable frame 503 are driven to synchronously move along with the movable frame 503, at the moment, the sector gears 510 meshed and connected above are driven to rotate along with the movement of the rack plates 511, the rotary shafts 504 connected between the sector gears 510 are driven to rotate between the two support plates 4, and the telescopic plates 505 connected with two ends of the rotary shafts 504 are driven to rotate by taking the rotary shafts 504 as circle centers, and in the rotating process of the telescopic plates 505, the transverse plates 512 can be stirred to slide along the route of the U-shaped through grooves 3 by rotating the connected columns 506;
when the transverse plate 512 slides along the path of the U-shaped through groove 3, the transverse plate 512 slides vertically and downwards from above, the collecting box 508 is driven to synchronously descend through the sliding column 513 and the connecting plate 507, when the collecting box 508 descends into the lithium sinking mother liquor and the transverse plate 512 still descends continuously, the connecting plate 507 is subjected to the buoyancy of the floating plates 509 at the two sides, the sliding column 513 is pushed to slide upwards on the transverse plate 512, and therefore the position of the collecting box 508 in the lithium sinking mother liquor can be always kept;
when the transverse plate 512 descends to a designated position in the U-shaped through groove 3 and cannot descend, the transverse plate 512 is stirred to horizontally slide in the U-shaped through groove 3 along with the rotation of the rotating shaft 504 through the telescopic plate 505 and the connecting column 506, so that the collecting box 508 connected below the transverse plate 512 is driven to horizontally move in the lithium precipitation mother liquor, at the moment, the floaters on the surface of the lithium precipitation mother liquor are limited by the inclined plane of one side of the floating plate 509 and can slide between the floating plate 509 and the collecting box 508, the floaters are completely collected, the floaters can be prevented from being deposited in the precipitation box 1, the frequency and the workload of cleaning and maintenance are reduced, the treatment cost is reduced, the phenomenon that the residual floaters are adhered to the precipitate after the recovery of the lithium precipitation mother liquor in the precipitation box 1 is completed, the quality of the precipitate is reduced, and the use value of the treated precipitate is reduced is avoided;
when the transverse plate 512 slides horizontally in the U-shaped through groove 3 until the transverse plate cannot slide, the transverse plate will continue to receive the thrust of the rotating shaft 504, slide vertically upwards along the U-shaped through groove 3, and drive the collecting box 508 connected below the transverse plate 512 to slowly separate from the lithium precipitation mother liquor, so as to facilitate the staff to process the collected floating objects;
in the process that the transverse plate 512 drives the collection box 508 to descend, the transverse plate 512 can drive the linkage blocks 703 to synchronously descend through the mounting plates 701 connected with the two sides, so that the limiting blocks 606 are contacted with the limiting blocks 606 connected with the side walls of the lower pressing plates 604, the limiting blocks 606 are pushed to synchronously descend, the lower pressing plates 604 push the lower pressing rods 603 with the equidistant connection of the lower end faces to slide into the air injection boxes 601, air in the air storage cavities 608 is ejected through the air injection ports 602, and floaters under the collection box 508 are automatically blown away from the collection box 508, so that the situation that the collection box 508 is leaked in the collection process because the floaters generated under the collection box 508 cannot be cleaned in the descending process is avoided;
when the lower pressure rod 603 cannot continuously descend, the linkage block 703 cannot continuously push the limiting block 606 to descend, at this time, the linkage block 703 is limited by the limiting block 606 and can rotate upwards on the fixed shaft 702, and simultaneously the torsion spring 704 is extruded, so that dislocation is generated between the linkage block 703 and the limiting block 606, the linkage block 703 and the limiting block 606 are separated, and when the linkage block 703 and the limiting block 606 are completely separated, the limiting block 606 can be automatically pushed to reset by the rebound force of the torsion spring 704;
when the cross plate 512 drives the collection box 508 to rise, the upper end of the linkage block 703 is contacted with the lower end of the limiting block 606, and is abutted by a spring 607 connected between the limiting block 606 and the sliding groove 605, so that the linkage block 703 can push the limiting block 606 to rise firstly, the lower pressure rod 603 is driven by the lower pressure plate 604 to slide out of the air injection box 601, air is sucked into the air storage cavity 608 for storage, when the collection box 508 is driven to collect floaters subsequently, the floaters below the collection box 508 are blown off, when the lower pressure plate 604 rises to be unable to rise, the upper end surface of the linkage block 703 and the lower end surface of the limiting block 606 are cambered surfaces, the limiting block 606 can be pushed to slide in the sliding groove 605 along with the continuous rising of the linkage block 703, the spring 607 is extruded, and after the linkage block 703 rises and the limiting block 606 is completely separated, the limiting block 606 is subjected to the rebound force of the spring 607, and then the linkage block 703 can be automatically reset, so that the limiting block 606 is pressed down subsequently.
