The driven filter plate 320 is provided with a through groove 321 for the first toggle lug 521 to pass through, when the pulling plate trolley 500 moves towards the fixed end plate 210, the first toggle lug 521 can not contact with the driven filter plate 320 any more, so that the first toggle lug 521 can not touch the positioning lug 531 and make the positioning lug 531 erect when passing over the driven filter plate 320, and further can not trigger the positioning action; until the first toggle ear 521 clears the active filter plate 310 of the next set of filter plate groups 300, the positioning ears 531 again rise and contact the active filter plate 310. Because the pulling plate trolley 500 can pull open a plurality of filter plates once, the speed of unloading filter residues of the filter press is improved, and the overall efficiency of slurry filtering is further improved.
After the pulling action of all the filter plates is completed, the trolley is pulled to move to one end, close to the fixed end plate 210, of the frame 100, at the moment, the second toggle lug 551 is abutted to the first reset block 610, the first reset block 610 toggles the second toggle lug 551 to rotate, the third limit block 554 moves towards the original direction of the second limit block 553, meanwhile, the first toggle spring 522 drives the first toggle lug 521 to rotate towards the limit lug 523, so that the first toggle lug 521 and the positioning lug 531 are not in a vertical state, and the limit lug 523 cannot automatically reset under the elastic force action of the first toggle spring 522; at this moment, the pulling trolley moves towards one end, close to the movable end plate 220, of the frame 100 until the second toggle lug 551 abuts against the second reset block 620, the second reset block 620 toggles the second toggle lug 551 to rotate, so that the third limit block 554 abuts against the second limit block 553 again, and thus the first toggle lug 521 can restore to the vertical state again to prepare for pulling the filter plate next time.
Example 2:
the embodiment of the application provides a high-performance filter press. Referring to fig. 5 and 6, the embodiment of the present invention is different from embodiment 1 in that the structure of the driven filter plate 320 is identical to that of the driving filter plate 310.
Referring to fig. 5 and 6, the transmission assembly 540 includes a first transmission lug 543, a second transmission lug 544, a linkage rod 545 and a fifth limiting block 546, the first transmission lug 543 and the second transmission lug 544 are both hinged to the vehicle body 510, the first transmission lug 543 is disposed between the first toggle lug 521 and the positioning lug 531, and the second transmission lug 544 is disposed between the first transmission lug 543 and the positioning lug 531. One end of the linkage rod 545 is hinged to the end of the first transmission lug 543 away from the vehicle body 510, and the other end is hinged to the end of the second transmission lug 544 away from the vehicle body 510, and the length of the first transmission lug 543 is greater than that of the second transmission lug 544. The fifth limiting block 546 is screwed or welded to the vehicle body 510, and the fifth limiting block 546 is disposed between the first toggle lug 521 and the first transmission lug 543.
The implementation principle of the high-performance filter press in the embodiment of the application is as follows:
in the initial state, the draw carriage 500 is located on the side of the frame 100 near the movable end plate 220. When the filter plate group 300 needs to be pulled, the plate pulling trolley 500 moves towards the fixed end plate 210, the first toggle lug 521 firstly passes over the driving filter plate 310 and then abuts against the driven filter plate 320 closest to the driving filter plate 310, the driven filter plate 320 toggles the driving filter plate 310 to rotate towards the first transmission lug 543, the linkage rod 545 and the second transmission lug 544 further drive the positioning lug 531 to rotate, and at this time, the positioning lug 531 is toggled to abut against the first limiting block 533 under the transmission action of the transmission lug 541; the pulling plate trolley 500 continues to move towards the fixed end plate 210, and at this time, when the first toggle lug 521 does not cross the current driven filter plate 320, the driving filter plate 310, the positioning lug 531 and the first limiting block 533 are sequentially abutted, so that the positioning of the pulling plate trolley 500 is realized.
Then the pulling plate trolley 500 moves towards the movable end plate 220, the limiting lug 523, the first toggle lug 521 and the active filter plate 310 can be abutted in sequence, at this time, the positioning lug 531 resets under the elastic force action of the second torsion spring 532, and the positioning lug 531 drives the first transmission lug 543 and the second transmission lug 544 to rotate towards the first toggle lug 521, so that the first transmission lug 543 is abutted to the fifth limiting block 546. The pulling cart 500 continues to move toward the movable end plate 220, and the first toggle ear 521 can drive the active filter plate 310 to move toward the movable end plate 220, and pull the current filter plate group 300.
The pull plate cart 500 is then moved again toward the fixed end plate 210 and is ready to pull the next set of filter plate groups 300. When the pulling plate trolley 500 moves towards the fixed end plate 210, the first toggle lug 521 is in contact with the driven filter plate 320, and the positioning lug 531 is erected under the transmission action of the transmission assembly 540; after the first toggle lug 521 passes over the current driven filter plate 320, because the distance between two adjacent driven filter plates 320 is larger, the positioning lug 531 rotates towards the second transmission lug 544 under the twisting action of the second torsion spring 532 before abutting against the driven filter plate 320, so that the positioning lug 531 does not contact with the driven filter plate 320, and the probability that the positioning lug 531 pulls the driven filter plate 320 towards the fixed end plate 210 is reduced. When the draw carriage 500 continues to move to the filter plate group 300, the positioning ears 531 may again resume the positioning function due to the smaller spacing between the driving filter plate 310 and the driven filter plate 320.
Because the structures of the driven filter plate 320 and the driving filter plate 310 can be completely the same, the interchangeability between the driving filter plate 310 and the driven filter plate 320 is improved, and the manufacture and maintenance supporting plates are saved; when the connecting lock 330 is disconnected, the plate pulling trolley 500 can automatically recognize and automatically pull the driven filter plate 320 closest to the movable end plate 220, so that the reliability of the filter press is improved, and the maintenance frequency is reduced.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
