Embodiment 2

[0042] The technical features of this embodiment that are the same as those of Embodiment 1 will not be repeated. The technical features of this embodiment that are different from Embodiment 1 are as follows: the bottom of the atomization chamber 5 is funnel-shaped. The funnel shape is conducive to the deposition of powder slurry, the slurry is concentrated at the bottom, and the slurry pump can pump all the slurry away, basically without slurry residue.

[0043] Preferably: the filter screen 11 is arranged at the lower part of the atomization chamber 5 .

Embodiment 3

[0045] This embodiment claims to protect the process of preparing any of the above-mentioned equipment for diamond alloy catalyst powder, including the following steps:

[0046] (1) smelting the catalyst alloy raw material in the metal smelting chamber 1;

[0047] (2) Exhaust the air in the atomization chamber 5 and fill it with protective gas through the exhaust gas charging valve 10 in the atomization chamber 5;

[0048] (3) Open the isolation valve 4 connecting the metal smelting chamber 1 and the atomization chamber 5;

[0049] (4) Pour the smelted alloy raw material into the tundish 2;

[0050] (5) Carry out water-gas combined atomization on the smelted alloy raw materials through the water-gas combined atomization spray plate 3;

[0051] (6) The slurry is drawn into the centrifuge by the slurry pump 6;

[0052] (7) Carry out preliminary dehydration by centrifuge;

[0053] (8) Transport the dehydrated water-containing material to the dryer 8 for drying.

Abstract

The invention discloses a device and technology for synthesizing alloy catalyst powder for diamond. The device comprises a metal melting chamber, a tundish, a water-gas combined atomization spray tray, an isolation valve, an atomization chamber, a slurry pump, a centrifugal machine and a drying machine which are sequentially connected. A melting furnace is arranged inside the metal melting chamber, the metal melting chamber further comprises the water-gas combined spray tray which is arranged on the lower portion of the melting furnace, the metal melting chamber and the atomization chamber areconnected through the isolation valve, the side wall of the atomization chamber is provided with a deflation and inflation valve, a filter net is arranged in the atomization chamber, the bottom of the atomization chamber is provided with the slurry pump, and the slurry pump is sequentially connected with the centrifugal machine and the drying machine. The probability that catalyst alloy makes contact with oxygen in the production process is greatly reduced, the oxygen content of final catalyst powder products is effectively reduced, and effective ingredients for synthesizing alloy catalyst powder for diamond are improved.

Description

technical field [0001] The invention relates to the technical field of diamond synthesis, in particular to equipment and a process for synthesizing alloy catalyst powder for diamond. Background technique [0002] As an allotrope of carbon, diamond is the hardest substance naturally occurring in nature due to its three-dimensional regular tetrahedral crystal structure. Diamonds are widely used, for example: cutting tools in industry, diamonds for geological drills and oil drills, diamonds for wire drawing dies, diamonds for abrasives, diamonds for dressers, diamonds for glass knives, diamonds for hardness testers, diamonds for handicrafts, etc. Wait. As early as 1955, General Electric obtained the world's first batch of small artificial diamond crystals for industrial use through special high-temperature and high-voltage electrostatic equipment, thus opening the door to artificial diamond. After decades of development, the industrialized synthetic diamonds currently on the ...
