Description

The invention relates to a filter press, each with a fixed head at the front and rear ends. a movable head between these, two side rails, which extend to both ropes from the front to the rear head, and a plurality of filter plates which are arranged transversely between the front and the movable head and have two laterally approximately horizontally attached arms by means of which they are men displaceably suspended, wherein under dei - on the two Settenho: P ¹ -'tentTiVUMi both sides G ^r zeal endless chain;)!

are attached to and fro, which paral-IeI to the spars and through a reversible Motor can be driven in one or the other kichiung.

After the end of the process, the compressed filler sections must be moved to one another. iuleü. 'Jarnii the i filter cake left between them can be removed. This is usually done by hand and is zeiinnux-nJ and cumbersome.

Tension of a spring 41 pivoted inward io In the foregoing it was assumed that will. This creates the lower end of the lever 36 as a group of retracted filter plates !! insmit a limit switch 43 (Fig. 12) in contact overall advanced by the movable head brings. The motor 20 is now activated by the signals of the. Now consider the case that this filter switch 43 set in counter-rotation; plates are moved forward one by one Sprockets 16 and 17 are clockwise 15 den. With all of the filter plates twist back rotated, and the running direction of the chain 15 will be reversed, the gripper 14 is gckchrt forward as described, whereby the gripper 14 runs back. As it moves, it hits the front hold-down device UO front pawl 49 under the action of tension spring 70 and stops. At this moment the shooters will be their normal position has returned, takes them in points of the pawls 49 and 50 of the gripper 14 in such a way at this moment the arm 13 of the rearmost filter 20 switched over, that when the gripping plate 5 moves forward and moves it backwards (Fig. 9). The heel 14 of the switching lever 52 that reaches it The rear pawl 50 descends under the hold-down device and abuts the projection 112, which is at the front 111 of the movable head 2, which is arranged in its return of the Seitcnholmcs 4. Since the gripper 14 has now ended (Fig. 10). If the filter is moved further, the universal lever 52. must like plate 5 meets the movable head 2, it must 25 shown in Fig. 11, remain at its projecting underneath, and thereby the gripper 14 also holds ren end 52 /) pivoting backwards into a position at the point where it got to. Hence the symmetrical to the original position of the relaxes Now the lower run of the chain 15, and the 52 /; is. Consequently, the top end 52 k of the for the same reason as above, the rear toggle lever 52 is in the opposite direction the chain 31 is pivoted an upward train 30 device, and the slide 46 thereby in the exercised. The front lever 35 pivots so moved forward in the groove. Accordingly, and the lower end of the lever 35 will move the pins 47 and 48 of the slide 46 into the a limit switch 42 (FIG. 13) in contact with longitudinal slots 56 and S7, respectively. The position of the pins 47 brings. The motor 20 is switched off by its signals and 48 has opposite the longitudinal contactors 56 and 57 the negative rotation is reversed into the positive rotation, as is clearly shown in FIG. 11. by comparison the chain 15 again counterclockwise with the position in FIGS. 8 to H), in the reverse direction is moved. The gripper 14 now begins reversing. So when the gripper 14 moves backwards to advance anew, and if in this eye will and the front pawl 49 against an arm 13 look the rear pawl 50 would be lifted immediately, the foremost filter plate hits and thereby the if it would have to grasp the arm 13 of the filter plate 5, the 40 front pawl 49 shifted to forward movement has been, and this again Li their tet, the second foremost arm 13, since the pin 48 Lead starting position. However, as clearly shown in Fig. 10 at the front end of the longitudinal slot 57, which is hincezelct Do not press down on the rear end of the üuerschlitzcs 57 terc latch 50, and if the a pin 48 arranged as a fulcrum. The ratchet gripper 14 changes direction and moves forward Hold-down 111 thus lowers the pawl 50, until the 45 begins to move, the pawl 50 is individually engaged i4 lifted back under the arm 13 of the rearmost one, grasps the arm 13 and moves it forward Filter plate 5 has passed. Downwards to the first filter plate 5. It does not need bcdem Passing the gripper 14, the pawl will first be mentioned separately that the further pre-50 is raised again and acts in the above-described way to advance the filter plates benen way as a stop. From this moment 5 ° are the same as the / üekfühan described above the function of hold-down 111 is exercised. After all filter plates are brought forward by the arm 13 of the retracted filter, the gripper 14 is retracted, plate 5. In this way, the gripper 14 goes and his Umschalthcbc! 52 is through the protrusion here, the filter plates 5 gradually move 113 on the rear part of the side member 4 to normal apart and lead them back. In the meantime 55 position returned and pins 47 and 48 return can also return the filter cu stuck in between to their original position with respect to to be removed. When all the filter plates 5 are closed, the longitudinal slots 56 and 57 back, and also the have been withdrawn, the gripper 14 moves front and rear pawls 49 and 50 are in it further forward until it is brought against the left Niederh ^ '- ren original state, so that the filter 110 comes to rest and stops. As soon as these plates are transported back, occurs, the gripper 14 comes with a border scarf. The device according to the invention allows it ter 114 in contact, and the reversible motor 20 to automatically ticnnen all filter plates and i'.ivuriike is brought out of the pressing position one after the other by the signals of the switch 114 for holding. The aforementioned limit switch 43 will ken. If necessary, all /11-a'.so not triggered. Then through the signals 65 withdrawn filter plates are individually to the front This switch 114 actuates the oil pressure cylinder 8 and moves the head of the filter press.
