Изобретение относитс к обогащению каменного угл путем разделени в водной среде и может быть применено в угольной и коксохимической отрасл х промышленности .The invention relates to the enrichment of coal by separation in an aqueous medium and can be applied in the coal and coke industry.

Известны устройства, включающие наклонные конвейеры с ребрами, представл ющие собой бесконечную ленту, движущуюс вдоль или параллельно уклону 1 или желоба, снабженные поперечными зигзагообразными перегородками 2.Devices are known that include inclined conveyors with ribs, which are an endless belt, moving along or parallel to slope 1 or a groove, provided with transverse zigzag partitions 2.

Эти устройства недостаточно эффективны , так как они требуют дополнительно установки больших количеств аппаратов дл перечистки.These devices are not effective enough, since they require the additional installation of large quantities of devices for cleaning.

Наиболее близким к предлагаемому по тех 1ической сущности и достигаемому эффекту вл етс устройство дл гравитационного обогащени , включающее транспортирующее приспособление с системой водонапорных труб и сочлененный с ним питающий желоб, выполненный в месте сочленени расширенным 3.The closest to the one proposed by those essence and effect achieved is a device for gravity enrichment, including a transport device with a system of water-supporting pipes and a feed chute coupled with it, made at the point of articulation extended 3.

Недостатком указанного устройства вл етс то, что оно .не обеспечивает достаточную эффективность процесса разделени , так как транспортирующее приспрсобление в этом устройстве захватывает и выносит из потока т желые примеси без их перечистки.The disadvantage of this device is that it does not provide a sufficient efficiency of the separation process, since the transport device in this device captures and removes heavy impurities from the stream without cleaning them.

Цель изобретени - повышение качества обогащени материала.The purpose of the invention is to improve the quality of enrichment of the material.

Поставленна цель достигаетс тем, что желоб снабжен внутренними бортами, закрепленными шарнирно в месте сочленени транспортирующего приспособлени с питающим желобом, к которым прикреплены пластины с фиксаторами, при этом пласти10 ны установлены с возможностью их свободного вертикального перемещени в плоскости бортов посредством пазов и зажимных болтов.The goal is achieved by the fact that the chute is provided with internal beads that are hinged at the junction of the transport device with the feeding chute to which the plates with clamps are attached, while the plastics are mounted with the possibility of free vertical movement in the plane of the beads by means of grooves and clamping bolts.

На фиг. 1 показано устройство, общий 15 вид; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - устройство, вид сверху; на фиг. 4 - пластина с крепежными элементами .FIG. 1 shows a device, a general view 15; in fig. 2 shows section A-A in FIG. one; in fig. 3 - the device, top view; in fig. 4 - plate with fasteners.

Устройство содержит желоб 1, наклоненный в начальной части под углом tti 15°, The device contains a chute 1, inclined in the initial part at an angle tti 15 °,

Claims

20a in a subsequent angle a d 12 ° articulated at an angle otj 90 ° (Fig. 3) with a scraper conveyor 2 having side walls 3 and a bottom 4. On the bottom 4 there are scrappers S in the guides 6 parallel to the longitudinal axis of the groove 1 , made with perforation 7. The chute 1 at its articulation with the scraper conveyor 2 is expanded (Fig. 3) and equipped with internal boards 8 mounted on hinges 9 with bolts 10 and nuts 11 (Fig. 4). With the help of flanges 8, bolts 10 and nuts 11, it is possible to narrow or expand the flow, change and fix its direction. Plates 12 are attached to the beads 8 (Figs. 2 and 4) located in the same plane with them and are their continuation. The plates 12 are equipped with grooves 13 and clamping bolts 14 (plates 12 increase the height of the beads 8). In the bottom 4 of the conveyor 2, a discharge opening 15 is made with trays 16 and openings 17 (Fig. 3) a pipe system 18 is brought to KOTOpbiM. The device operates as follows. The device is installed in the chute feeding the jigging machine so that the flow of coal with water going to the jigging machine is fed into the narrow part of chute 1 formed by the beads 8. In the chute and in its narrow part the coal grains separate so that the heaviest of them ( pyrite, iron), are lowered to the bottom of the gutter and then fed to the bottom 4 of the conveyor 2, from where they are moved with the help of scrapers 5 in the direction of the discharge opening 15, through which they go to the trays 16. The light grains of coal and rock continue to move along the gutter 1 and , mine scrapers Conveyor 2, entrained with water flow to the jigging machine. In order to create water pressure for extracting the lung-containing particles carried by the scrapers 5 together with pyrite and iron, the coal plate 12 of the bead 8 is lowered from the side of the discharge opening 15, and the plate 12 of the bead 8 located on the opposite side is lifted. The reinforced overflow, formed in such a way, flushes the light grains of coal out of the scrubbers carried away by heavy impurities and attaches them to the total coal flow going to the jigging masses. For a more intensive extraction of coal from the material carried by the scrapers 5 and the middling from below, pipes 18 supply an additional upward flow of water. The economic effect of the proposed invention consists of reducing the loss in rock of the fraction with a density of less than 1.5 t / m by 0.2% and the middling of the fraction 1.5-1.8 t / m 3 by 0.3%. Claim 1. A device for gravitational enrichment of ores, including a transporting device with a system of water-supporting pipes and a feed chute articulated with it, made in the place of articulation extended, characterized in that, in order to improve the quality of enrichment, the chute is provided with internal boards fixed pivotally in the place of articulation to which the plates with clamps are attached, the plates being installed with the possibility of their free vertical movement in the plane of the beads. 2.
