Before the driving column 24 performs the first station and the second station, the driving column 24 is moved up, so that the convex sliding blocks 62 on the driving column 24 abut against the upper end of the first spiral groove 612, so that the driving column 24 drives the second driving sleeve 61 to move up, and at this time, the insert 65 enters from the vertical through hole 641 and keeps moving up slowly, so that the second driving sleeve 61 drives the plurality of cover plates 63 to move up under the action of the insert 65, and the sliding rods 631 on the plurality of cover plates 63 slide in the short vertical channels 661, and the plurality of sliding rods 631 are arranged up and down above the short vertical channels 661; at this time, the convex sliding block 62 on the driving column 24 slides in the first spiral groove 612 to rotate the second driving sleeve 61, so that the insert 65 on the second driving sleeve is clamped into the transverse embedded hole 642 on the sleeve 64 and drives the lowermost cover plate 63 to rotate, and meanwhile, the sliding rod 631 on the cover plate 63 slides in the transverse arc path 662 to take out the lowermost cover plate 63; simultaneously, the downward moving driving column 24 makes the convex sliding block 62 slide in the vertical groove 613 and reach the groove low position 614, so that the downward moving driving column 24 directly drives the second driving sleeve 61 to move downward, so that the second driving sleeve 61 drives the cover plate 63 to move downward, the sliding rod 631 slides in the long vertical channel 663, the cover plate 63 performs extrusion filtering treatment on the sulfate compound and water stored in the collecting cover 52, and the filtered sulfate compound is accumulated between the collecting cover 52 and the cover plate 63 for storage.

Meanwhile, when the slide bar 631 reaches the ring path 664, the driving column 24 is moved upwards again, so that the convex slide block 62 is separated from the lower slot 614 and enters the second spiral slot 615, at this time, the convex slide block 62 slides in the second spiral slot 615 to realize the circumferential rotation of the second driving sleeve 61, meanwhile, the sliding bar 631 on the cover plate 63 slides in the ring path 664 to realize the rotation of the cover plate 63, and the cover plate 63 increases the included angle between the elastic slide plate 672 and the cover plate 63 in the downward moving process, but still keeps the contact with the cover plate 63, and the included angle is increased along with the deformation of the fourth elastic piece 671, and when the cover plate 63 rotates, the elastic slide plate 672 can scrape and push the upper surface of the cover plate 63, so that the residual sulfate compound on the upper surface of the cover plate 63 is pushed to the hole 673 by the action of the elastic slide plate 672, and the residual sulfate compound can be sent between the collecting cover 52 and the cover plate 63 for storage; when the slide bar 631 starts from the intersection of the bottom port of the long vertical channel 663 and the loop 664, and rotates for one third of a turn, the slide bar 631 abuts against the touching block 682, so that the pressing force acts on the first elastic push plate 571 through the first lock bar 5711, so that the first elastic push plate 571 deforms and is temporarily bent in the cavity, at this time, the fifth elastic member 683 on the locking long rod 68 resumes deformation, and the locking long rod 68 is received in the vertical long groove again, so that the locking long rod 68 and the locking piece 681 thereon are disengaged from the hole on the cross frame 67, unlocking of the cross frame 67 is achieved, and at the same time, under the action of restoring deformation of the fourth elastic member 671, the cross frame 67 moves down to close the cover plate 63, so that the elastic scraper 672 closes the hole 673 after scraping and the assembling work of the lowermost cover plate 63 and the collecting cover 52 is completed, so that the collecting cover 52 is convenient to filter and store the sulfate compound.

Finally, the curved first elastic push plate 571 has a restoring deformation force, after the transverse frame 67 is unlocked and the elastic scraping plate 672 on the transverse frame 67 seals the hole 673 on the cover plate 63, the reaction force of the restoring deformation of the first elastic push plate 571 acts on the locking long rod 68 again, so that the touching block 682 on the first elastic push plate 571 acts on the end part of the sliding rod 631 to enable the sliding rod 631 to reversely rotate, at this time, the sleeve 64 on the cover plate 63 rotates on the side wall of the second driving sleeve 61, so that the insert 65 on the second driving sleeve 61 is separated from the transverse embedding hole 642 and enters the vertical penetrating hole 641, and the second driving sleeve 61 can be separated from the current cover plate 63; when the driving column 24 moves up again and prepares for the next first station and second station, the protruding sliding block 62 on the driving column 24 is separated from the second spiral groove 615 and enters into the reversing groove 616, and simultaneously, the third elastic piece 621 recovers deformation, so that the protruding sliding block 62 slides from bottom to top and reaches the position of the first spiral groove 612, and under the action of the first spiral groove 612, the second driving sleeve 61 is driven to rotate again, so that the insert 65 is clamped into the transverse embedded hole 642 on the other cover plate 63 again, and the second driving sleeve 61 realizing the upward movement can be assembled with the next cover plate 63 without the notch 673 again, so that after the lowest cover plate 63 and the collecting cover 52 are assembled and stored, the redundant cover plate 63 can provide an additional collecting period of the collecting cover 52, and the plurality of cover plates 63 can still store sulfate compounds in the collecting cover 52 in a layered manner when the collecting cover 52 is not removed for a long time.
