Abstract

Use: mining of minerals from the bottom of the sea. The essence of the invention: a flexible carrier is fixed on the watercraft. To the media attached working bodies and the boot element. The latter is made in the form of a hollow cylinder and mounted on a dredging unit. The device is equipped with an electromagnet, which is fixed on the inner surface of the loading element. A switch and an electromagnet switch are installed at the inlet and outlet of the loading element. The outer surface of the loading element is made of non-magnetic material. 1 hp f-ly, 2 ill.

Description

This invention relates to the extraction of minerals with magnetic susceptibility from underwater deposits.

Various types of dredging plants are known, using which the entire volume of minerals is extracted to the surface and then enriched on board the mining vessel or ashore.

A known dredge for subsea mining with the enrichment of magneto-susceptible minerals, comprising a magnetic conveyor operating partially under water. The beneficiation and supply of minerals is carried out by loosening the sand around the conveyor with water supplied under pressure through nozzles installed on the conveyor (auth. St. Ns 390275, class E 21 C 45/00). This dredge is ineffective, because the area of underwater mining is limited by shallow depths due to the restriction of the length of the conveyor and significant energy expenditures on soil loosening on the seabed limited by the width of the conveyor.

A device for the extraction and transportation of solid minerals from the seabed and the ocean floor is known, including a flexible carrier with scoops mounted on it and a bottom dredging unit interacting with a flexible carrier (A.P. № 909182, cl. Е 21 С 45/00) Known The device eliminates the disadvantages of the above dredge, but does not enrich the production, which makes it ineffective.

The purpose of the invention is to increase the productivity of mining.

This goal is achieved by the fact that in a device for underwater mining with the enrichment of mineral resources, including flexible media with working bodies attached to it, interacting with a loading element in the form of a hollow cylinder mounted on a dredging unit, it is equipped with an electromagnet attached to the inner surface of the loading element. It is supplied as well; the switch and switch of the electromagnet installed according to

at the entrance and exit of the loading element and interacting with the working bodies. The outer surface of the loading element is made of non-magnetic material.

In Fig. | Presents the proposed device, a general view; figure 2 - bottom dredging unit.

“. The device for subsea mining with the enrichment of polar minerals, mounted on vessel 1, contains flexible carrier 2 with working bodies attached to it 3. Flexible carrier 2 passes through the bottom dredging unit 4, the loading element 5 of which is made in a hollow cylinder with an outlet 6 and an inlet 7 of the movement of the working bodies 3. The dredging unit 4 is equipped with a baking powder 8. An electromagnet 9 is fixed on the inner surface of the loading element 5. The switch 10 and the switch 11 of electromagnet 9 are located along the movement working bodies 3 at the inlet 7 and outlet 6 of the boot element 5. The outer surface of the boot element 5 is made of non-magnetic material.

The device works as follows.

The bottom dredging unit 4, when moving, loosens minerals that are sucked inward into the loading element. The magnetic particles are attracted to the inner surface of the loading element by the action of the electromagnet 9. The empty rock, which is a non-magnetic material, under the action of the flow of water and the movement of the aggregate leaves the latter. The traction mechanism mounted on the vessel 1 drives the flexible carrier 2 with the working bodies 3. The working bodies 3 at the entrance to the loading element 5 interact with the switch 10, the electromagnet 9 is turned off, and the working body 3 collects the magnetic rock. When exiting unit 4, the operating element 3 interacts with the switch 11, and the electromagnet is again switched on. The process is repeated.

The use of such a device for underwater mining and mineral processing is not limited to the underwater depth of magnetosensitive minerals, ensures the continuity of the production process and increases its productivity.
