The invention relates to chemical engineering, the technique of high pressure diamond synthesis, in particular for growing crystals of large sizes, the growth process which requires a long time.

Currently, the synthesis of (growing) of the diamond crystals is to employ a multi-piston (multi-punch) devices with high-pressure chamber in the shape of a cube or octahedron, or other polyhedra.

The known high-pressure apparatus (EN 2071823, published. 20.01.1997)containing multi-punch unit, with the outer surface of a regular polyhedron, each punch is a right pyramid with a truncated apex. The base of this pyramid is one of the outer sides of multi-punch unit, and a truncated top of one of the sides of the compressible volume. The container consists of two semi-bodies, between which lies an internal cavity in which is put a multi-punch unit. It has the form of a polyhedron corresponding to the shape of the outer surface of the multi-punch unit. Multi-punch unit in the flexible sealing cover, the edges of which are in the field of connector sealed on the surface of the semi-bodies, placed in the internal cavity of the container. The high pressure fluid is supplied to the camera high on the means between the flexible cover and the surface of the internal cavity of the container. Effort, perceived the outer surface of the plunger is transmitted to its truncated top, which has a smaller area, resulting in the internal volume of a high pressure.

The size of the high-pressure chamber, its volume and the pressure is limited by the force presses, power frames or containers through which creates a high pressure in the chamber. Consumption of materials and energy power designs for high-pressure cells of large volume is very large.

The objective of the invention is the creation of a high-pressure apparatus with low material and energy intensity.

The technical result of the invention consists in the exclusion of the apparatus of power structures and compressors by providing the possibility of using the natural pressure of the water column created by the gravitational field.

This technical result is achieved in that the high-pressure apparatus contains multi-punch unit, which is enclosed in a sealed flexible membrane and at least two sealed cavity, at least one of which is connected through the valve with the external environment to fill with water when submerged, and the second cavity is a motor with a pump for pumping water from the first sealed cavity when lifting the machine.

In addition to t the th, the technical result is also achieved by the fact that:

in the same second sealed cavity is a pipeline system with valves remote control for filling at least one sealed cavity water and for pumping of water, and controls and process control-related sensors process control, placed in the high-pressure cell multi-punch unit, and valves remote control;

- multi-punch unit can be installed on a sealed hollow platform having at least two sealed compartments forming the above, at least two sealed cavity;

in another embodiment, a multi-punch unit is installed on a sealed hollow platform having at least one sealed compartment that forms the specified at least one first sealed cavity and one of the punches multi-punch unit is made hollow with the formation of the second specified sealed cavity in which is located the specified engine with pump;

- the machine can be equipped with a compressed air tank connected to the pipeline via an automatic valve with the first sealed cavity for emergency lifting apparatus;

platform can be fitted with an anchor, buoy and rope, which is fixed to the power cables.

Figure 1 shows the diagram of the first variant of the high-pressure apparatus, figure 2 - scheme of the second variant of the device.

The high-pressure apparatus contains multi-punch unit, which in turn consists of several blocks of punches. Each of these blocks includes punches in the form of monolithic plates 4 and the plug 5.

Monolithic plate 4 have the shape of truncated pyramids whose vertices are sent to the center apparatus, and smaller base of one of the plates is in contact with a large base of another. These punches perceive the highest voltage in the generation process pressure.

The punch 5 is experiencing a small voltage and is a continuation of pyramidal punch - plates 4. These punches have 5 frame design, are hollow and sealed inside.

In the particular case of the outer surfaces of the punches 5 are segments of a sphere, so that the external surface of the multi-punch unit is represented by a sphere. But it may also have the shape of a regular polyhedron with faces by the number of blocks, punches, frequent in the spine of the shape of a cube. The number of punches in each block can be different. Punches are made from materials, the strength of which a maximum of punches in the center of the camera and is lower for punches 5 on the periphery.

The outer side of the multi-punch unit is enclosed in a detachable sealed elastic membrane 6, which prevents the penetration of liquid into the unit. Through the shell 6 are sealed 8 inputs, connected via punches with cell 2 high pressure and serve to supply power to the heater and the sensors monitoring pressure and temperature.

Multi-punch unit having a negative buoyancy, is mounted on a hollow sealed platform 1, which provides positive buoyancy of the entire apparatus. In the first embodiment (figure 1) within the platform 1 has at least two sealed compartments. In the compartment 10 is installed, the motor 11 with a pump, piping system connecting the cavity of the other compartments of the platform 1 and the inner cavity of multi-punch unit with the external environment and with the pump. On pipelines installed valves 12-16 remote control. In the compartment 10 is also fitted with control units and control associated with sensors monitoring pressure and temperature, with the valves remote control and with other elements of the hydraulic and electrical circuits.

<> In the second case (figure 2) one of the punches 5 has a cavity in which is located the motor 11 with the pump and piping system with valves 12-15 remote control, and the control units and control.

In the third embodiment, when multi-punch unit has its own positive buoyancy, at least two of the punches 5 are made with sealed cavities, one or more of which is filled with water when diving through the valves remote control, and then removed when lifting the machine, and the other cavity are the engine 11 with the pump and piping system. In this case, the apparatus similar to the apparatus shown in figure 2, only in this case, the platform is only for the stability of the apparatus on the ground.

For disaster recovery in case of failure of the engine 11 or the pump apparatus is equipped with a compressed air tank connected to the pipeline via an automatic valve with the first sealed cavity (not shown).

The apparatus operates as follows. Cubic cell 2 high pressure for growing diamonds going in a known manner. It set the sensors process control. The cell is placed in the centre of multi-punch unit. The high-pressure chamber initially consists of five blocks, punches, separated by elastic strips 7. The rear sensors the La process and cables heater cells 2 connected through sealing glands 8 external cables 8. Install the latest sixth block punches, and assembled multi-punch unit seal elastic membrane 6 and mounted on the platform 1.

The pressure in the chamber to create the following way. Apparatus with connected cables to heat and control the operation are placed in water, or in the mine, flooded with water. Open the valves 12, 13 and 16, the internal cavity of the platform 1 (or punch 5) is filled with water, and the apparatus is submerged under water. With increasing depth of immersion in a cubic chamber will increase the pressure. If we neglect the losses of the load on the compressive elastic strips 7, the pressure in the chamber will be equal to the external pressure, multiplied by the ratio of the larger square base pyramidal block punches to the square of its smaller base, located closer to the top of the pyramid. For the area of the larger base is projected area of the outer surface of the block punches on a plane that is parallel to the lower base. Upon reaching the desired pressure in the chamber temperature rises and begins the process of synthesis of diamonds.

At the end of the process turns off the heating system. To reset the high pressure closes the valve 14 includes the motor 11 of the pump is pumping water from the cavity of the platform 1 (or punch 5). As water pumping devices, which rises due to the buoyancy force, until you reach the surface. Then perform the depressurization apparatus, separate electrical connectors, pull the top block punches and remove the cell from the grown crystals. After the chamber cleaning process can be repeated.
