Description
Technical field
The utility model belongs to the diamond synthesis technical field, particularly a kind of high grade coarse granule diamond synthesizer.
Background technology
In the at present domestic diamond synthetic technology, usually adopt the cubic hinge press compacting synthetic, its synthesizer is to put the synthetic stem of being made by catalyst and diamond raw material in the cavity of pyrophyllite in lumps, and the two ends of stem are respectively arranged with graphite sheet and isometrical conducting steel ring.And, avoid producing the concentrated and ablated damage of stress in order to protect the top hammer, increase the volume of synthetic cavity as far as possible, cause the diameter of conducting steel ring also to increase thereupon.Though this synthesizer is structurally fairly simple, but because the conducting steel ring surface area is big, heat scatters and disappears big, the pyrophyllite in lumps wall thickness is thin and poorly sealed in addition, thereby have that firing rate is slow, sealing and heat insulating ability be poor, defectives such as anti-pressure ability is low can't adapt to high grade, the coarse granule diamond crystals needs to high temperature, high pressure, long-time growth conditions.Therefore, existing synthesizer can only be produced low and middle-grade times, fine grain diamond, and the diamond of producing reach 30/40 granularity above only account for 5%, not grade not having basically more than ZND2140, and the diamond crystal surface that produces has damaged, there are defectives such as bubble crackle inside, impacts index Ti value＜50%, TTi value＜30%, isostatic pressing strength value 10kgf～15kgf.The external coarse granule diamond method of employing usually of producing is to utilize belt type press to carry out high temperature, high pressure to synthesize the diamond poor toughness that this kind method synthesizes for a long time.
The utility model content
The purpose of this utility model is to propose a kind ofly can to produce the compression strength height, impact flexibility is good, the high grade diamond that internal soundness is good, and output height, power consumption are less and the high grade coarse granule diamond synthesizer of basic improvement is being arranged aspect sealing, the heat insulating ability.
Realize that the technical scheme that the purpose of this utility model is taked is: this device has pyrophyllite in lumps synthetic sleeve chamber, conductive ring, graphite heating sheet, wherein, inwall in the sleeve chamber is embedded with the external insulation insulating tube and the interior thermal insulating pipe of cover tubular, be provided with heating tube between the inside and outside insulating tube, the synthetic stem of diamond raw material is equipped with in the centre, the upper and lower side of stem stem is respectively arranged with thermal insulating sheet, interior conductive metal sheet and heat insulation loop, is coated with the metallic conduction circle in the heat insulation loop.
Described metallic conduction circle is to be made of outer conducting strip and diameter contact tube less than outer conducting strip, wherein, outer conducting strip is concordant with the end face in pyrophyllite in lumps sleeve chamber, and its diameter equates with the internal diameter of end, sleeve chamber, the insulation filler is equipped with in the inside of contact tube, and outer cover is equipped with heat insulation loop.
Can be the weldment of split between described outer conducting strip and the contact tube, also can be the single piece that is connected as a single entity.
Described heat insulation loop is made up of white clouds stone ring and pyrophyllite ring, and the white clouds stone ring contacts with interior conductive metal sheet.
The two ends wall thickness of described pyrophyllite in lumps is arranged at least more than the 10mm.
Diamond synthesizer according to the such scheme making, what not only can guarantee the production temperature effectively imports uniformity with cavity heating into, and can strengthen the sealing of synthetic cavity, reduce area of dissipation, improve the heat-insulating property of synthetic cavity, can also satisfy simultaneously the needs that prolong generated time, thereby reach the requirement of coarse granule high grade diamond growth.Use the synthetic diamond of this device, its granularity is reaching more than 50% more than 30/40, and the diamond particles of grade more than ZND2140 can reach 30%, and lustrous surface, flawless, it is golden yellow that color is, transparency is good, impacts index TTi and reaches 84%, and isostatic pressing strength is more than 25kgf.Compared with prior art, it is fast that this device has firing rate, and the production efficiency height consumes advantages such as electric energy is few.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, high grade coarse granule diamond synthesizer of the present utility model, form by pyrophyllite in lumps sleeve 1, conductive ring 2, pyrophyllite heat insulation loop 3, dolomite heat insulation loop 4, interior conductive metal sheet 5, thermal insulating sheet 6, stem stem 7, interior thermal insulating pipe 8, heating tube 9 and external insulation insulating tube 10, for strengthening the intensity and the sealing in pyrophyllite in lumps sleeve chamber, prolong generated time, the wall thickness at the two ends of pyrophyllite in lumps sleeve 1 is set at least more than the 10mm.Cavity inner wall at pyrophyllite sleeve 1 is embedded with external insulation insulating tube 10 and the interior thermal insulating pipe 8 that overlaps tubular, is provided with heating tube 9 between the inside and outside insulating tube, effectively imports synthetic cavity into to guarantee heating tube production temperature.Catalyst powder and the synthetic stem stem 7 of diamond raw material are equipped with in the cavity centre of pyrophyllite in lumps sleeve 1, the two ends of stem stem 7 have been put thermal insulating sheet 6, interior conductive metal sheet 5, dolomite heat insulation loop 4 and pyrophyllite heat insulation loop 3 respectively, be coated with metallic conduction circle 2 in the heat insulation loop, dolomite heat insulation loop 4 contacts with interior conductive metal sheet 5.Conductive ring 2 is to be made of outer conducting strip and diameter contact tube less than outer conducting strip, can be the weldment of split between the two, also can be the single piece that is connected as a single entity.Wherein, outer conducting strip is concordant with the end face of pyrophyllite in lumps sleeve 1, its diameter equates with the internal diameter of sleeve ends, the insulation filler is equipped with in the inside of contact tube, can reduce the heat dissipation metal area, guarantee that effectively the temperature in the cavity is not spread, the outer cover of contact tube is equipped with heat insulation loop, can strengthen the sealing of synthetic cavity.
This device is assembled in each member in the pyrophyllite sleeve chamber by described structure earlier, and the synthetic stem stem of making of catalyst bortz powder is inserted in the synthetic cavity carrying out diamond when synthetic, and integral body is placed on and carries out pressurized, heated in the cubic apparatus machine then.Under the effect of the pressure of cubic apparatus and top hammer, conduction heating by conductive ring, conducting strip and heating tube, make stem stem be warming up to setting range rapidly, and pyrophyllite ring and white clouds stone ring by the contact tube outside, and pressure transmission, the insulation effect of the pyrophyllite in lumps sleeve of thickening, make the quick generation and the growing environment that form good diamond kind grain in the synthetic cavity, can synthesize the high-grade diamond product of coarse granule through cubic apparatus pressure machine again.
