Description

The utility model relates to drags and is intended for the development of predominantly flooded, including man-made alluvial mineral deposits.

Known multi-pack dredges (Handbook for the development of placers, editors: V.P. Berezin and other eds. Nedra, Moscow, 1973 p. 177, fig. 39 (1), chap. 11 p. 181 ÷ 199) including a pontoon with a device for its movement and fixation, a superstructure, a scoop device with a drive and a suspension for raising and lowering it, washing and processing equipment, devices for removing pebbles and tails, and auxiliary equipment and devices, including lifting equipment. The above dredges are distinguished by the complexity of the enrichment process.

Closest to the proposed utility model is a multi-dredge dredge (the same source, p. 180, 181), including a flat-bottomed steel pontoon with a rope-pile device for its movement and fixation, a superstructure with front and rear towers, on which are mounted a scoop device, respectively and a dump conveyor (hereinafter stacker).

The superstructure is equipped with enrichment equipment, technologically connected with each other, with a scoop device, a stacker and with tail decks, including a three-part drainage barrel (hereinafter referred to as a scrubber-boot) and locks (jigging machines). Dredge is also equipped with a water supply system, including for ensuring the operation of the processing equipment, with various auxiliary devices and equipment. Dredge is notable for the simplicity of the technological process, but does not provide the necessary quality of enrichment and the level of yield of a useful product.

The objective of the utility model is to improve the quality of ore dressing and the yield of a useful product.

The utility model problem is solved in that in a multi-shell dredge containing a pontoon body, a superstructure, technologically interconnected processing equipment, including a scoop device, a scrubber-buter with a distributor, jigging machines, a stacker, tail (drain) decks, as well as water supply systems and various auxiliary equipment, in accordance with the proposed solution, three additional ore concentrate dressing stages are included in the dredging enrichment system, located sequentially after deposition machines, which are the first stage and including two second stage cleaning machines, two third stage cleaning machines, a fourth stage concentration table, and jigging machines are connected to second stage cleaning machines through two auxiliary devices, the first of which is a pulp preparation device (hereinafter ZUMPF) from concentrate supplied, incl. from jigging machines, and feeding it with a sand pump to devices (hereinafter hydrocyclones) for dewatering and purifying the sludge from the concentrate pulp. In addition, the third stage cleaning machine and the concentration table are connected by tail feed pipelines from these devices to ZUMPF.

Thus, additional concentrate enrichment stages included in the dredging enrichment system provide an increase in the yield of a useful product. In addition, the possibility of feeding tailings from the third stage cleaning machine and from the concentration table to ZUMPF, with the aim of their repeated and repeated enrichment, also increases the yield of the useful product and avoids complicating the construction of the dredge, which increases its efficiency.

Thus, a useful model allows us to solve the problem.

Analysis of the information available at the enterprise allows us to conclude that the proposed utility model is new.

The utility model is illustrated by drawings:

figure 1 shows a General view of the dredge;

figure 2 shows the composition of the processing equipment and the scheme of its interaction.

Multi-pack dredge includes a body in the form of a flat-bottomed pontoon 1 with a pile device for its movement and fixation (not shown), a superstructure 2 with front 3 and rear 4 towers, on which a scoop device 5 and a dump conveyor (stacker) are installed, respectively. 6. The dredge is equipped also tail drain decks 7.

Enrichment equipment technologically connected with devices 5, 6, and 7 was installed in superstructure 2 (Fig. 2): scrubber-butyro 8 with distributors 9, jigging machines 10 — the first stage of concentrate enrichment, two cleaning machines 11 — the second stage, two cleaning machines 12 - the third stage, the concentration table 13 - the fourth stage of enrichment. Jigging machines 10 are technologically connected with the cleaning machines 11 through two auxiliary devices: ZUMPF 14 with a sand pump 15 and a hydrocyclone 16, and tail pipes for draining tailings from the cleaning machines 12 and the concentration table 13 are connected by pipelines to ZUMPF 14.

Dredge is also equipped with a water supply system, including for ensuring the operation of processing equipment (not shown) and various auxiliary devices and equipment.

To capture and process a small part of the ore falling past the filling tray (not shown) of the scrubber-butary 8, the dredge is equipped with an under-pack well with gratings and locks (not shown).

Multi-pack dredge works as follows.

When emptying the scoops of the scoop device 5, the rock is fed through a filling tray (not shown), where washing water is also supplied, to the scrubber buter 8 equipped with an irrigation system. In its scrubber-butyr during its rotation and ore washing under pressure, disintegration and subsequent screening occurs. where the screening part of the rock is screened out. The latter enters the stacker 6 and is removed to the dump. The subsurface product enters the distributor 9, which evenly distributes the product for feeding it by means of hydrotransport (by gravity) to the jigging machines 10 - the first stage of enrichment. From jigging machines, tails (85%) from drain trays (not shown) enter the tail (ephemeral) decks 7 in the dump. Concentrate from the drain holes flows by gravity to ZUMPF 14. In the latter, a pulp is formed (the concentrate is mixed with water) and is fed into the hydrocyclones 16 by the sand pump 15, where the concentrate is partially dehydrated, washed from the sludge, which is also discharged into the decks 7. From the hydrocyclones, the concentrate by gravity fed to the scraping machine 11 (second stage), where after enrichment it enters the scraping machine 12 (third stage), and 85% of the tails go to the tail decks 7.

In the cleaning machines 12, the concentrate is further enriched, in which 85% of the product (tailings) is sent to ZUMPF 14 and then to secondary enrichment, and the rest of the concentrate is sent to the concentration table 13. On the concentration table, the gold head is separated and sent to a special tank 17, and tails by gravity are fed for recycling at ZUMPF 14. Removal of the oversize useful product in jigging and scraping machines is done manually.
