(54) SORTING DEVICE

.

This invention relates to separation.

materials by thickness and can be used to classify materials in different industrial areas, for example in the microfinishing industry.

A sorting device is known, comprising a drive, a loading and a reload device, receivers of separation products and two cylindrical concentrically arranged sieves having square and longitudinal apertures 1.

A disadvantage of such a device is the impossibility of sorting complex materials, such as mica, by thickness.

The closest in technical essence and the obtained result to the proposed is a sorting device, including a frame mounted on a clone, a frame mounted with the possibility of rotation concentrically with the axis of the frame a roll of variable cross section, decreasing in the course of the material movement.

fixed for rotation, longitudinal movement and fixation in a predetermined position C 2.

The disadvantages of this device are the rapid plugging of the source material, the impossibility of self-cleaning of the screening surface and the mechanical adjustment of the roll space.

The purpose of the invention is to prevent clogging of the inter-roll space and its self-cleaning.

The goal is achieved by the fact that in the sorting device, incl. mounted inclined housing, frame, installed with the possibility

15 of rotation is concentric with the axis of the frame, rolls of variable cross section, the part of which VU has a diameter decreasing in the course of the material movement, and the rolls have the possibility of longitudinal movement and

20 fixings in a predetermined position, and the loading unit, another part of the rolls, has a diameter that increases along the two pieces of material, and these rolls are outlined alternating with the first vagas, which are equipped with mechanisms for longitudinal movement and fixation in the predetermined position and are located on the frame periphery , and on the case in the upper case is installed a copier. In this case, the mechanism of longitudinal movement and fixation in a predetermined position is made in the form of an adjustable stop, a spring, a pusher and a locking plate. The boot unit is made in the input per perforated drum. FIG. 1 shows a device for longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 1. The sorting device consists of a tray 1, a loading unit 2, made in the form of a perforated drum, a rotating frame 3, with a tip of the axis along the periphery of which there is a portion of the rolls 4 of variable cross section, the diameter of which decreases along the movement of the material. The other part of the rolls 5 has a diameter that increases the movement of the material, and these rolls are placed transversely with the first rolls. All the rolls are rigidly connected to rotating satellites 6, which are engaged with the stationary solar ko forest 7. The rolls 4 have meccism. longitudinal movement and fixation in a predetermined position. It consists of axes 8 and 9 5 of the anchoring springs 10, adjustable stops 11 with pushers 12 and locking bars 13. The welding of the end wall of the corspus 14 is fixed by the copier 15 and the entire beam with beams 4 and 5 is driven in rotation by the drive 16 through a V-belt transmission with hooks 17 and 18 and a gearbox 19. The undersize product is transported from the place of sorting by the conveyor 2O, and the grate is transported by the conveyor 21. The sorting device operates as follows. Laminated material such as crystal. ly of the mica together with non-commodity fines, are fed through tray 1 to the loading unit 2, which rotates together with the frame 3-, the drive 16 through the timed transmission with the pulleys 11g and 18 and the gearbox 19. At the same time the non-commodity fraction falls through the perforated surface of the loading unit 2, and the conditioned product enters the inside of the drum formed by the frame 3 with the rollers 4 and 5, which rotate together with the frame 3 and also, by engaging the satellite 6 with the sun wheel 7, rotate around its own axis. Mica plates that are thinner than the width of the inter-roll space fall into the slot and get onto the 2O conveyor belt, which trans Ygorts them to the point of consumption, and those plates that are thicker than the inter-roll space slide down the inclined rolls and unload onto the conveyor 21. When the frame rotates, 3 pushers 12 bump at the upper point of rotation on the copier 15, while the roll 4 moves the axes by the thickness of the copier 15, increasing the roll-over space and freeing the crystals stuck in it, which leads to self-cleaning of the working surface sorting device. The adjustment of the inter-roll space is made by screwing or unscrewing the pusher 1.2. ъ the body of the adjustable stop 11, which interacts with the spring 1O, which leads to a longitudinal displacement: roll 4 and a corresponding change in the space between the rolls. Fixing the pusher in a predetermined position of production. It is possible to prevent clogging of the rolling room and significantly improve its self-cleaning. The classification of laminates by thickness on the sorting device can be done in a flow, which increases the productivity of sorting operations with a high quality classification. The proposed sorting device is convenient to use and allows adjustment to different thicknesses of the sorted materials. Claim 1. Sorting device, which includes an inclined body, a frame, rolls of variable cross section mounted rotatably concentric to the frame axis, some of which have a diameter decreasing in the course of material movement, and the rolls have the possibility of longitudinal movement and fixation in a predetermined position, and a loading unit, similar to the fact that, in order to prevent the inter-roll space, and its self-cleaning, another part of the rolls has a diameter increasing along the material movement, and these rolls are made alternating with the first rolls, which are equipped with mechanisms of longitudinal movement and fixation in a predetermined position and are located on the periphery of the frame, and a copier is mounted on the case in the upper position. 2. The device according to claim 1, wherein the mechanism for the longitudinal movement and fixation in a predetermined position is made in the form of adjustable an emphasis, springs, a pusher and lock shshnki. 3. The device according to claim 1, wherein the boot unit is in the form of a perforated drum. Sources of information received during the examination 1. USSR author's certificate number 61383O, cl.
