    2. A device for carrying out the method according to claim 1, comprising a centrifugal mixing chamber having a circular cross-section, with a tangentially installed inlet and outlet nozzles and an axial nozzle for suction of the pulp, which is equipped with an additional nozzle installed a convex outside the axial nozzle and hydraulically communicated with the cavity of the centrifugal mixing chamber.
    The invention relates to hydromechanization and is intended for collecting soil from under water.
    There is a known method for collecting soil from under water and a device for its implementation. According to the method, the pulp is sucked in by a submersible ground pump and transported through pipes II.
    The disadvantage of the method and device for its implementation is a large abrasive wear of the soil pump.
    The closest technical solution to the invention is a method of collecting soil from under water, including feeding a centrifugal mixing chamber having a circular cross section, pressurized water with creating a reduced pressure in the center of the chamber, sucking the pulp through the axial nozzle and releasing its dp transport along tangential exhaust pipe.
    The apparatus for carrying out the method comprises a centrifugal mixing chamber having a circular cross-section, with a tangentially mounted inlet And outlet nozzles and an axial nozzle for sucking pulra 2j.
    However, the known method and device for it. the implementations are characterized by insufficient productivity of the soil-collector.
    The aim of the invention is to increase the productivity of the primer by lowering the pressure in the center of the chamber.
    This goal is achieved by the fact that, according to the method of collecting the soil from under water, including the flow into the centrifugal mixing chamber, which has a circular cross-section, pressurized water with the creation of a reduced pressure in the center of the chamber,
    through the axial nozzle and its release for transportation through the tangential outlet nozzle; a part of the pressure water is diverted in the axial direction from the center of the chamber to the water.
    A device for collecting soil from under water, containing a centrifugal mixing chamber having a circular cross-section, with a tangentially set inlet. and outlet nozzles and an axial nozzle for suction of the pulp, equipped with an additional nozzle installed concentrically outside the axial nozzle and hydraulically communicated with the cavity of the centrifugal mixing chamber.
    FIG. 2 shows an apparatus for carrying out the method; 2, a device control system.
    The device for implementing the method includes a centrifugal mixing chamber 1 containing a circular side wall 2 and days 3 and 3. The high-pressure inlet 5 is attached to the side wall 2 so that the material flowing through the nozzle 5 enters tangentially into the chamber 1. The exhaust nozzle A high pressure 6 is welded to the side wall, 2. A suction pipe of 7 g; connected to the bottom 3 along its axis. The location of the pipe 7 would coincide with the low pressure axis in the chamber 1 and not necessarily coincide with the geometric axis of the chamber 1. The low pressure outlet 8 attached to the bottom 3 of the chamber coaxially with the suction pipe 7 The chamber 1 can be supported, for example, with cables 9, which are attached to the carriage 10 above the liquid 1 in the sump 2 on the rails 13. The supports 4 support the inner tube 7.
    Water collection system 15 is connected via line 16 to na3I
    The sump 7, which in turn is connected to the pipe 18 and moves the water down through the pipe 19 and the valve 20. The sump 12 has water storage tanks 21 and material 22, the water is removed from the tank 21 of the 1G sump pipe 23 by means of a pump 24 having an outlet connected to a hose 25, which injects high-pressure water into the inlet 5 of the chamber 1, the outlet 6 is connected via a flexible pipe 26 to the inlet 27 of the vortex and 1 section of the injector apparatus 28, which serves to lift the material to the surface
    The vortex :: injection apparatus 28 contains a low pressure port 29 connected via pipe 30 via control valve 31 and pipe 32 to sump 12. The high pressure side of vortex injector injection pump 28 contains a pump 33J which pumps water through pipe 34 out of sump 12 and delivers it to the outlet 35. The high pressure side is connected via pipe 36 of the control valve 37, check valve 38 to the pipe 39, which is connected to another pipe 40 from the control valve 20. The pipe 39 is also connected to the regulator it has a valve 41 and a pipe 42, which is connected to a high pressure inlet 43 from a vortex injection device-injector 28. A high pressure nozzle 44 is connected to a pipe 45 designed to remove material from the mine to the surface of the earth where the material is located in the surface sump 46. the surface sump 46 is removed through a second pipe 47, which is connected to the pump and connected to the beneficiation plant. The material can be slurried by means of the stirrer 48. The separated water from the factory returns via conduit 49 to the water collection system 15.
    35454
    The method is carried out as follows.
    Water from the factory through pipeline 49 enters the water collection system 15 and passes through pipeline 16 by pump 17 to the second pair of pipes 18 and 19 and further to control valve 20. Valve 20 regulates the amount of water entering the lower mine. valve 20 is guided through pipe 40 through control valve 41, through pipe 42 to the high pressure inlet of the vortex injector 28. High pressure pipes 44, which are mixed with the suspension in the manner described above, are connected via pipe 45 to the sump 46 on the surface. The material is slurried in a mixer 48 and fed through a pipe 47 to a beneficiation plant. The centrifugal chamber 1 is located in the sump 12 by means of the trolley 10 on the direction to the cich 13 so as to position the nozzle 8 above the ma
    material that needs to be rolled out. The pump 24 pumps out water from the water storage tank 21 through the pipe 25 to the high pressure port 5 of the chamber 1. As the liquid moves in the chamber 1 in a circle, some of the liquid goes down the pipe 7. Also some of the fluid goes through the port 8. Moving the fluid around a circle in chamber 1 and with a small outlet through the low-pressure pipe 8 causes turbulence. The pressure in the center of the chamber 1 is lower than the pressure in the suction part of the nozzle 8;
    As a result, the material flows through the nozzle 8 into the chamber 1, mixes with the liquid and moves through the outlet nozzle 6 connected by means of the pipe 26 to the inlet 27 of the vortex injector 28, which pumps the slurry to the sump 46.. :
    The proposed device makes it possible to increase the productivity of the grouser by reducing the pressure in the center of the chamber.
