Patented in the German Empire on January 20, 1906.

The present invention relates to sorting or sorting apparatus in which the Sorting shredded materials into any number of sorts can be effected, with a stream of air is used in a known manner, the individual types of material on their To make the paths to the conveyor channels dust-free.

This is done by a number among themselves

ίο arranged sieves causes between which conveyor belts in a known way the move material falling through the sieves from one sieve to the other.

According to the present invention, the goods rolling over the sieves pass through one each overflow associated with each sieve into a specific sorting channel, and all these sorting channels are arranged in such a way that when the inclination of the sieves changes, the position the overflows are changed accordingly in order to always maintain the mutual relationship to obtain.

In the drawing, an embodiment of the invention is shown in section.

In the sorting vessel G z. B. by means of a blower fan B in a known manner, an air flow is generated through which air is drawn from the sorting vessel into a dust trap D , where the from the. Dust particles coming into the sorting vessel are collected.

The sorting vessel consists of a box 1, in which the material to be sorted is introduced through a hopper 2. The material falls on a distribution plate, which extends across the upper end of a sieve 4.

z. B. made of wire mesh.

This sieve is made up of those particles of the

Introduced material, which pass through this sieve, fall on an endless one Belt 5, which is continuously driven below the screen in such a way that the on it incoming material is moved upwards. Those particles which pass through the sieve 4 cannot fall through, roll in over an overflow 6 at the lower end of the sieve a channel for discharging the coarsest products, which, if desired, can be brought back under the mill. Those However, particles which have fallen through the sieve 4 and get onto the belt 5 are moved upwards through this belt worn and there delivered to an underlying sieve 7, the mesh openings are smaller than those of the sieve 4. On this sieve 7 are again those particles which cannot fall through the sieve mesh, over at the lower end of this sieve an overflow 9 directed to a special channel, while the particles that have fallen through again get onto a belt 8 moving under the sieve 7 and guided upwards are to be passed to a sieve 10, the meshes of which are smaller than that of the sieve 7 and so on until the material conveyed by the belt 11 is brought onto the sieve 13 which in the present embodiment has the smallest mesh size. That Material that cannot fall through this sieve 13 rolls over here again an overflow 14 into a special channel, while the particles falling through to the

Fördcrplattc 15 arrive and be directed into a fifth channel. The endless ribbons are all provided in a known manner with drivers that prevent the slipping of the on them Prevent falling material. As can be seen, the device shown secretes this. brought in material in five different sorts, which through five different channels their further use ίο can be, but it goes without saying that the number of sieves and belts can be changed at will. The delicacy of the various The type of material depends on the angle at which the screens are arranged. To the inclination of the sieves depending on the To change the type of material to be treated, the following facility is in place: The Sieves are connected to one another by rods 16 and 17. · The rods 16 are open a rod 18 rotatably attached, which passes through the upper part of the box 1. The lower Ends of the sieves are suspended from chains 19 which are connected to rods 17 and are wound on drums 20 which are arranged on a shaft 21 can. This is done, for example, by a hand crank, if desired, the to lift the lower ends of the sieves and thereby change their inclination. To the Control for the shaft 21 can be arranged a locking mechanism of any known device will. In accordance with the present invention, overflows 6, 9, 12 and 14 have one of 'The sieves have independent support so that they do not take part in the shaking movement of the sieves take part. The bands 5, 8 and 11 are mounted in a frame which consists of the Struts 25, 26 and the side supports 27 and 28 consists. The supports 27 are rotatable arranged on the same shaft 18 which also carries the sieves, while the supports 28 are connected by chains 29 to the drums 20 so that the belts simultaneously can be lifted with the seven so as not to change their relationship to the seven. The overflows 6, 9, 12 and 14 are attached to supports 30, which with the supports 28 are connected so that when the screens are moved to their inclination change, not only the belts, but also the overflows are changed accordingly, the relationship between the means provided for transporting the material not to affect. In order to keep the different types of product pure and to prevent the fine material from slipping with the different types of coarser products, an air flow is normally obtained in the vessel G , which flows in the opposite direction to the conveying direction of the material. The advantageous arrangement of the whole apparatus prevents the unpleasant escape of dust, while at the same time the finest dust is removed from the coarser products. Patent-A ν saying: Sorting device for sorting different material sizes, in which the separate goods pass through individual overflows into certain sorting channels, characterized in that the overflows with the one arranged under the sieves and adjustable at the same time as the sieves Frame for the conveyor belts are connected in such a way that when the position of the sieves and conveyor belts change Overflows can be converted accordingly. 1 sheet of drawings.
