MULTI-CHAMBER DEVICE FOR GROWING LARGE DIAMOND CRYSTALS Russian patent published in 2019 - IPC B01J3/06 C30B29/04 C01B32/26 

FIELD: machine building.

SUBSTANCE: invention relates to chemical engineering, high pressure engineering and can be used for growing large diamond crystals. Device comprises power frame 1, installed in it coaxially in a row of cylindrical containers 2, 3 with installed in each container corresponding multi-punched high-pressure apparatus 4 in the form of a cube, in which diamonds are grown, semi-cylindrical inserts 5 are installed between extreme containers 2, 3 and power frame 1, cylindrical surface of each of which is in contact with reciprocal semi-cylindrical surface of frame 1. Between inserts 5 inside power frame 1 on opposite sides of row of containers 2, 3 there are struts 6. Struts 6 and inserts 5 have grooves to receive high-strength tape. Container 3 also serves to seal a pack of containers on axle in frame 1. Pressure in each container is created and maintained separately from one pump station through a system of controlled gates and valves.

EFFECT: production of large diamond crystals in a large volume is possible at moderate costs using only one power frame, in which several containers with high-pressure apparatus are placed.
