The invention relates to a device for the production of nodules from the seabed and their transportation through the pressure pipe to the base ship.

A device for the production of nodules from the seabed, including basic vessel, a movable bottom unit with intake device, discharge pipe, while the suction device Assembly has a housing in the form of a perforated pipe that provides transportation nodules in the desliming of the pulp, and the size of the holes of the perforated part of the pipe passed less than the minimum size of the extracted nodules (A.S. USSR №1761957, CL E 21 50/00, 1992).

The disadvantages of the known devices is the inability to simultaneously dewatering and desliming of the pulp before it is transported through the pressure pipe to the base ship, as well as the inability to achieve the specified degree of dewatering of the pulp.

It is known device that can be used in the extraction of nodules from the seabed, made in the form of a pipe with slotted perforations to ensure output of the cavity of the excess water, and the tube is in the form of a truncated cone and has a variable cross-sectional area to decrease this square aside from pulmonalis, which feeds the pulp (A.S. USSR No. 70384, CL E 02 F 3/90, 1948).

Not the remnants of the known device is the complexity of manufacturing the steel pipe in the form of a truncated cone and the complexity of the design, as well as the deterioration of the technological properties of the device in the manufacture of a perforated pipe section with a stepped reduced diameter. Our studies revealed that the actual conditions of the production of ferromanganese nodules from the Baltic sea shelf the length of the perforated section of the pipe must be not less than 6-7 meters. When the length of the perforated zone of the discharge pipe manufacturing steel pipe conical shape is very difficult, as it requires the development of special technologies and equipment. In addition, when performing the perforated zone of the steel pipe is possible clogging of the holes of the so-called hard grains nodules.

Objectives of the invention are to simplify and reduce the cost of the device and improving the efficiency of its work.

The tasks are solved due to the fact that the device for the extraction of nodules containing bottom power unit associated with the base of the vessel pressure pipe with a conical perforated section adjacent to the bottom of the power unit, according to the invention a conical perforated portion of the pressure pipe made from a sheet of elastic material and provided at their ends by rigid pipes with flanges, with the flanges of the pipes are connected Krugozor is suspended by chains, placed around the perimeter of the flanges, which are connected with the flanges of the socket of the power unit and the discharge pipe. As the elastic material can be used rubberized tape with a frame made of synthetic fabric. Edges of the sheet, forming a conical surface can be lapped with rivets. Edges of the sheet can be connected back to back with the hinge loops.

Device for nodule mining is presented in figure 1, a side view, figure 2 is a perforated pipe section, figure 3 is a cross section of figure 2 when the connection of the sheet overlap, figure 4 - the same, when connecting sheet butt.

Device for nodule mining consists of the power unit 1, connected to the pressure pipe 2 adjacent to the power unit 1 section 3 the discharge pipe 2 is made conical (figure 2), with decreasing diameter towards the base of the vessel 4. The conical section 3 of the discharge pipe 2 perforated holes 5 and is made of elastic material, for example, made of rubberized tape with a frame made of synthetic fabric.

Conical perforated portion 3 of the discharge pipe 2 is formed from a sheet, which is rolled into a tube of conical shape. Edges of the sheet during formation of the pipe conical shape can be interconnected overlap (Phi is .3) with rivets 6. Edges of the sheet can be connected end-to-end (figure 4) with hinge loops 7.

Conical perforated portion 3 of the discharge pipe 2 is provided at its ends by rigid pipes 8 and 9 with flanges 10 and 11, with which it is connected to the flange of the socket 12 of the power unit 1 and the flange 13 of the discharge pipe 2.

The flanges 10 and 11 of the nozzles 8 and 9 are interconnected kruglozerny circuits 14 placed around the perimeter of the flanges 10 and 11.

Device for nodule mining operates as follows. When the power unit 1 of the pulp, containing nodules of various fractions and the slurry, under pressure in the pressure line 2 to the perforated stage 3 due to excess pressure compared with the geodetic pressure through the holes 5 removes excess water, substandard fraction of nodules and sludge.

Due to the fact that the perforated portion 3 of the discharge pipe 2 is made of elastic material (cushioning rubberized tape) in the holes 5 is not jamming hard grains nodules that increases the efficiency of the device.

When the movement of the power unit 1 and the curves of the discharge pipe 2 of the longitudinal forces occurring in the delivery pipe 2 and transmitted to its perforated portion 3, are not perceived by the tube of elastic material, and all the tier chains 14. Therefore excluded breaks perforated section 3 the discharge pipe 2. Due to the increased flexibility of the perforated zone 3 the discharge pipe 2 increases the maneuverability of the power unit 1. Due to the excessive pressure of the pulp in the perforated portion 3 of the discharge pipe 2 when it bends not happening deformation in the cross section of the perforated zone 3 penstock 2.

Features of the invention can simplify and reduce the cost of the device for nodule mining, to improve the efficiency of its work.
