The invention relates to a device for screening goods containing balls and balls, with rods arranged above the sieve surface and rotating around a common axis for loosening the ball and ball.

A material to be screened that contains balls and balls is lost especially when lead-acid batteries are scrapped at. Here, the lead batteries are crushed in a hammer mill and the crushed battery scrap then, for example on a vibrating sieve, sieved. The sieve passage consists of fine scrap, which consists of Pieces of the housing and the lead plates assembled. The sieve residue, on the other hand, contains the Separators that cannot be crushed in a hammer mill, which are in the use stage of the accumulators ensure the even spacing between the lead plates. The highly elastic, mostly made of Thin plastic sheets of existing separators form balls and balls in the hammer mill, in which still contain a considerable part of the fine scrap. In order to win this fine scrap too, the balls and balls had to be loosened manually and repeated on the vibrating screen to be abandoned.

For the treatment of household and commercial waste, a system is known that, among other things, a Has sieve grate, arranged below the grate bars and through the space between the grate bars penetrating, motor-driven knife stars are provided, with the help of which the Rubbish sliding down over the grate bars is to be loosened and partially crushed. This arrangement has the disadvantage, however, that balls or balls contained in the material to be screened, especially those made of elastic materials, such as those contained in battery scrap Represent separators, are not loosened, but by the rotating knife stars the grate openings are pulled through. Therefore, these components get back into the already sieved Good.

A vibration sieve is also known in which a hammer rotor is arranged above and at the end of the sieve surface, which grabs large pieces of the material located on the sieve surface and hurls them against baffles arranged above the rotor and thus comminutes them. However, such an arrangement is not suitable for the treatment of material to be screened which contains balls or balls, especially those made of elastic materials. The bales are only thrown up and not as a device for sieving balls
and goods containing bales

loosened so that the remaining fines also fall out of the bales.

The invention is now based on the object of what has hitherto been customary and is dubious for safety reasons To make manual intervention unnecessary and to create a device that the complete Screening of the fine fraction in a single continuous operation is made possible.

According to the invention, this is done in that the axis of rotation of the rods is perpendicular to the screen lining or is arranged inclined or that the circular movement in a parallel to the screen lining or inclined circular plane is located.

In a further embodiment of the invention it is proposed to arrange the rods in such a way that the distance between the rod ends and the screen lining and / or the angle between the common axis of rotation of the rods and the screen lining is adjustable.
In addition to rotating rods, elements such as fingers, claws, arms, shovel-like or knife-like metal sheets and the like, which are attached to driven belts, chains, rotating shafts, disks and the like, can also be used as means for loosening .

During the screening process, the balls and balls are moved by those that engage in the conveying area of the material to be screened Detects rods and thus prevented the sieve carrying large proportions of fine scrap too fast to go through. At the same time, the balls are perpendicular to and against the conveying direction of the sieve moved and inevitably turned when the distance and the inclination of the device are properly adapted to the structure of the goods to be processed. It has been shown that the This treatment loosens up balls so much that the enclosed fine scrap is also loosened up is obtained as a sieve passage. The whole process

can be rationalized by the fact that the sieving under water supply or on an underwater vibrating sieve takes place, because then the lead sludge adhering to the separators with the sieve passage is won.

Other organs, such as crushing snails known from conveyor technology (»Hut«, 2, 24th edition, p. 579) or fork-like swathers commonly used in agriculture are for the intended purpose unsuitable as they either grasp the goods too tightly and do not turn them or are too delicate are and do not have the versatile adjustability, which is very important for the result.

In the drawing, the device according to the invention is shown as an example and schematically. It is attached to a vibrating screen of known construction. Mixed scrap prepared in a hammer mill reaches a sieve 2 via an inlet 1. The sieve passage arrives at an outlet 3, while the overflow, that is, the balls and balls, migrate in the direction of arrow 4 over a screen covering 5. A device consisting of a motor 6, a reduction gear 7 and a plurality of rods 9 fastened to the circumference of a rotatable plate 8 is attached above the sieve 2. The entire device rests on a supporting frame, not shown, which allows the device to be pivoted in the region of the angle B in different directions, the device can be adjusted laterally and the distance from the screen covering 5 can be adjusted. During operation, the bars 9 revolve about an axis 10. The mutual spacing of the bars is adapted to the width of the screen and the material to be treated in such a way that no mixed scrap can pass through the screen unhindered. The rods 9 rotating with the plate 8 loosen the mixed scrap by moving it vertically to and against the conveying direction 4 over the screen covering 5. Since the distance between each of the bars 9 and the screen lining 5 changes periodically between a maximum value and a minimum value with each revolution according to the slope B, the bales are slowly turned and loosened when the distance A and the slope B of the device are appropriately set . The bales are caught and loosened by the sieve vibrations from constantly changing directions, so that the trapped fine scrap is recovered as a sieve passage.

The device specially developed for the processing of accumulator scrap is also for the Processing of other types of scrap and rubbish of a similar structure is suitable.
