The invention relates to hydraulic devices for the extraction of nodules from the seabed.

A device for the production of nodules from the seabed (prototype), containing the basic vessel, a movable bottom unit with pulponasosnoj and outlet pipe, discharge pipe, perforated pipe, which is connected by flanges with outlet pipe and a pressure pipe, the dimensions of the holes of the perforated pipe is taken equal to the minimum size of the extracted nodules (U.S. Pat. Of the Russian Federation No. 2219342, CL. 7 E 21 50/00; E 02 F 3/88, 2003).

However, a disadvantage of the known device is the increased length of the perforated zone of the discharge pipe, which reduces the maneuverability of the mobile bottom of the unit and makes the work associated with moving the bottom of the unit.

The technical result is achieved in that the device for the extraction of nodules from the seabed containing a movable bottom unit with pulponasosnoj and outlet pipe, discharge pipe, base ship, the perforated portion of the pressure pipeline, connecting flanges, according to the invention, the perforated portion of the pressure pipe made of placed parallel pipes connected distribution pipe with the outlet pipe of pulmonalis and pressure pipe, and the diameter and number of tubes perforated zone is determined from the ratio of D 2=D1/,where D1- diameter of pulmonalis, D2,n is the diameter and number of tubes of the perforated zone of the discharge pipe.

Device for extraction of nodules from the seabed presented in figure 1, a side view (the perforated portion is deployed 90 degrees); figure 2 - site installation of the perforated zone of the discharge pipe; figure 3 is a cross section of the perforated zone, consisting of two pipes; figure 4 - the same, in the presence of three pipes; figure 3 - the same, with four pipes.

Device for extraction of nodules from the seabed contains a movable bottom unit 1 pulponasosnoj 2, the discharge pipe 3, the basic vessel 4 and the perforated portion 5 of the discharge pipe 3. The perforated portion 5 consists of several parallel set of tubes, through which the flanges 6 and 7 are connected with transition pipes 8 and 9, and these pipes with flanges 10 and 11 are connected with the outlet pipe 12 pulmonalis 2 and pressure pipe 3. The number of pipes perforated section 5 the discharge pipe 3 is determined from the ratio of D2=D1/,where D1the diameter of the outlet pipe 12 pulmonalis, D2, n is the diameter and the number of perforated pipes at Asda 5 discharge pipe 3. While the perforated portion 5 may consist of two pipes 13 and 14 (n=2, 2 and 3), three pipes 15, 16 and 17 (n=3, figure 4), four pipes 18, 19, 20 and 21 (n=4, figure 5). Perforation 22 in the pipes 13 and 21 may be in the form of holes or slotted channels of different forms. The diameter and the total area of holes in perforated pipe is selected depending on the minimum size of nonconforming fractions nodules and planned degree of thickening of the slurry after the bottom of the unit 1. These same parameters are determined and the diameter D3the discharge pipe 3, 23 - benthic zone.

The parameters of the pipeline system devices can be adopted in the following. For example, when the diameter of the outlet pipe 12 pulmonalis 2 D1=300 mm and the number of pipes perforated section n=2, the diameter should be equal to D2=210 mm, n=3 D2=173 mm, for n=4, D2=150 mm Diameter discharge pipe 3 when you double the thickening of the pulp on a perforated portion 5 discharge pipe 3 may be taken equal to D3=210 mm

Device for extraction of nodules from the seabed operates as follows.

When working Polonaise 2 slurry containing concretions and sludge component and, as a rule, excessive dilution, through the outlet 12 and a distribution nozzle 8 is supplied in tubes 13, 14 or pipe 15 17 or pipe 18-21 perforated holes 22 section 5 discharge pipe 3. Due to the excess pressure through the holes 22 in the pipes perforated section 5 removes excess water, a significant portion of the sludge and substandard fraction of nodules that remain in the bottom zone 23, and condensed and enriched slurry through a distribution pipe 9 enters the discharge pipe 3, and on it - on the base ship 4. By increasing the total area of the holes 22 due to the presence of several parallel placed pipes constituting the perforated portion 5 discharge pipe 3, significantly reduced the length of the perforated section 5. This provides greater maneuverability mobile bottom unit 1 and reduces the volume of work associated with movement of the discharge pipe 3 in the extraction of nodules. For example, when performing a perforated section 5 of the two pipes 13 and 14, the length of the perforated section 5 is reduced by 25%, with three pipes 15-17 at 42%, with four pipes 18-21 - 50%.

Features of the invention allow for the expense of carrying the perforated zone of the discharge pipe of several placed in parallel pipes to reduce the length of the perforated zone, depending on the number of pipes, 25-50%, increase the maneuverability of the mobile bottom of the unit and reduce the complexity of the work when moving the pressure line is the gadfly in the process.

Device for extraction of nodules from the seabed containing a movable bottom unit with pulponasosnoj and outlet pipe, discharge pipe, base ship, the perforated portion of the pressure pipeline, connecting flanges, characterized in that the perforated portion of the pressure pipe made of placed parallel pipes connected distribution pipe with the outlet pipe of pulmonalis and pressure pipe, and the diameter and number of tubes perforated zone is determined from the ratio of D2=D1/where D1- diameter of pulmonalis, D2, n is the diameter and number of tubes of the perforated zone of the discharge pipe.
