Description

Technical Field

[0001] The utility model relates to the technical field of diamond, in particular to an energy-saving synthetic assembly block for artificial diamond. Background Art

[0002] Diamond, commonly known as "drill", is a mineral composed of carbon elements, an allotrope of graphite, with the chemical formula C, and is also the original body of common diamonds. Diamond is the hardest substance naturally existing in nature. Graphite can form artificial diamond under high temperature and high pressure.

[0003] In the process of artificial synthesis of diamond, the synthetic assembly block method needs to be used for synthesis. The assembly block for synthesizing superhard materials under ultra-high temperature and high pressure is a block assembled by a graphite column for synthesizing diamond, conductive steel rings located at both ends of the graphite column, heating tubes, insulating elements and pressure-transmitting and sealing media around the graphite column in a certain way.

[0004] At present, the existing synthetic assembly blocks for diamond generally have general heat preservation effect, resulting in unstable quality problems during the conversion of diamond. Therefore, an energy-saving synthetic assembly block for artificial diamond is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an energy-saving synthetic assembly block for artificial diamond to solve the problems put forward in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: an energy-saving synthetic assembly block for artificial diamond, including a synthetic column, a heating mechanism, a filler and an outer frame are arranged on the outer side of the synthetic column, the filler is located between the heating mechanism and the outer frame, and conductive plugs are arranged on both the upper and lower sides of the outer frame;

[0007] The heating mechanism includes an isolation sleeve, a lining tube, a heating element and a heat preservation element. The isolation sleeve is located on the outer side of the synthetic column, the lining tube is located between the heating element and the isolation sleeve, and the heat preservation element is located on the outer side of the heating element.

[0008] Preferably, the isolation sleeve is hermetically coated on the surface of the synthetic column, and the isolation sleeve is made of metal foil. The isolation sleeve plays the role of conducting electricity and isolating impurities.

[0009] Preferably, the lining tube is movably inserted into the heating element, the heating element is sleeved on the surface of the isolation sleeve, and the heating elements are evenly distributed on the surface of the isolation sleeve. The heating element plays the role of auxiliary heating.

[0010] Preferably, the synthetic column is a graphite column made of graphite and metal catalyst materials.

[0011] Preferably, the heat insulation sleeve is sleeved on the surface of the heating element. The heat insulation member is made of fibrous heat insulation material. When the heating element is energized to generate heat, the heat dissipation around the synthesis column is reduced through the heat insulation member.

[0012] Preferably, the diameters of the two conductive plugs are both larger than the diameter of the synthesis column. The conductive plugs are pressed on the outer wall of the isolation sleeve, and the side surfaces of the conductive plugs are in contact with the inner side surfaces of the outer frame. The conductive plugs are used for conducting electricity. The larger diameter of the conductive plugs than that of the synthesis column is beneficial to electricity conduction and pressure transmission. The heating element is energized through the conductive plugs, and the heating element generates heat when energized, and then a high temperature is formed around the synthesis column.

[0013] Preferably, the filler is filled in the inner cavity of the outer frame, and the filler is pressed on the surface of the heat insulation member.

[0014] Preferably, the outer frame is made of cold-rolled plate material, and the filler is made of dolomite material. When the outer frame is under pressure, it will be transmitted to the synthesis column through the bushing and the heating element. When the heating element shrinks, the heating element will not hinder the movement of the conductive plug. Then the upper and lower pressures are transmitted to the synthesis column through the conductive plug, the filling layer and the liner tube. Then the synthesis column is in a state of high temperature and high pressure, and the molecular structure inside it changes, and a part of the graphite will be converted into diamond.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: for this energy-saving artificial diamond synthesis assembly block, through the heating mechanism, the wall thickness of the liner tube increases, enhancing the pressure conduction of the liner tube to the synthesis column. Thus, the synthesis column is not easily deformed during diamond synthesis, thereby improving the safety of diamond production. At the same time, the heating element is used to assist in heating the synthesis column, improving the temperature uniformity inside the synthesis column. The heat insulation member plays a heat insulation effect on the heating element, thereby reducing the heat loss of the synthesis column, and thus improving the quality and conversion rate of diamond; the conductive plug is used for conducting electricity. The larger diameter of the conductive plug than that of the synthesis column is beneficial to electricity conduction and pressure transmission, greatly reducing the power consumption and the cost of diamond synthesis; when diamond is generated, the six-sided top press applies pressure to the assembly block, and at the same time, the heating element is energized through the conductive plug. The heating element generates heat when energized, and then a high temperature is formed around the synthesis column. When the outer frame is under pressure, it will be transmitted to the synthesis column through the bushing and the heating element. When the heating element shrinks, the heating element will not hinder the movement of the conductive plug. Then the upper and lower pressures are transmitted to the synthesis column through the conductive plug, the filling layer and the liner tube. Then the synthesis column is in a state of high temperature and high pressure, and the molecular structure inside it changes, and a part of the graphite will be converted into diamond. When the heating element generates heat when energized, the heat dissipation around the synthesis column is reduced through the heat insulation member. Description of the Drawings

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0023] Please refer to Figure 1 - Figure 5 , the present utility model provides a technical solution: an energy - saving synthetic diamond assembly block, including a synthesis column 1. A heating mechanism 2, a filling material 3 and an outer frame 4 are arranged outside the synthesis column 1. The filling material 3 is located between the heating mechanism 2 and the outer frame 4. Conductive plugs 5 are arranged on both the upper and lower sides of the outer frame 4;

[0024] The heating mechanism 2 includes an isolation sleeve 201, a liner 202, a heating element 203, and a heat insulation member 204. The isolation sleeve 201 is located outside the synthesis column 1. The liner 202 is located between the heating element 203 and the isolation sleeve 201. The heat insulation member 204 is located outside the heating element 203. The isolation sleeve 201 is hermetically wrapped on the surface of the synthesis column 1. The isolation sleeve 201 is made of metal foil. The liner 202 is movably inserted into the heating element 203. The heating element 203 is sleeved on the surface of the isolation sleeve 201. The heating elements 203 are evenly distributed on the surface of the isolation sleeve 201. The synthesis column 1 is a graphite column made of graphite and a metal catalyst. The heat insulation member 204 is sleeved on the surface of the heating element 203. The heat insulation member 204 is made of fibrous heat insulation material. Through the heating mechanism 2, the wall thickness of the liner 202 increases, enhancing the pressure conduction of the liner 202 to the synthesis column 1. Thus, during diamond synthesis, the synthesis column 1 is not easily deformed, thereby improving the safety of diamond production. At the same time, the heating element 203 is used to assist in heating the synthesis column 1, improving the temperature uniformity inside the synthesis column 1. The heat insulation member 204 has a heat insulation effect on the heating element, thereby reducing the heat loss of the synthesis column 1, and thus improving the quality and conversion rate of diamonds.

[0025] The diameters of the two conductive plugs 5 are both larger than the diameter of the synthesis column 1. The conductive plugs 5 are pressed on the outer wall of the isolation sleeve 201. The sides of the conductive plugs 5 are in contact with the inner sides of the outer frame 4. The conductive plugs 5 are used for conducting electricity. The larger diameter of the conductive plugs 5 than the diameter of the synthesis column 1 is beneficial for conducting electricity and transmitting pressure, greatly reducing the power consumption and the cost of diamond synthesis.

[0026] The filler 3 is filled in the inner cavity of the outer frame 4. The filler 3 is pressed on the surface of the heat insulation member 204.

[0027] The outer frame 4 is made of cold-rolled plate material. The filler 3 is made of dolomite material.

[0028] In use, during assembly, first insert the heating element 203 into the interior of the outer frame 4, and sleuth the heating element 203 outside the isolation sleeve 201. Then insert the liner tube 202 into the interior of the heating element 203, sleuth the heat preservation member 204 outside the heating element 203, and insert the synthesis column 1 into the interior of the bushing 7. The isolation sleeve 201 is sleuthed outside the synthesis column 1. Then fill the filler 3 between the heat preservation layer 204 and the outer frame 4. Finally, press the conductive plug 5 on the outer wall of the isolation sleeve to complete the assembly of the synthesis assembly block. When generating diamond, the six-sided top press applies pressure to the assembly block, and at the same time, the heating element 203 is energized through the conductive plug 5. The heating element 203 generates heat when energized, and thus a high temperature is formed around the synthesis column 1. When the outer frame 4 is under pressure, it will be transmitted to the synthesis column 1 through the liner tube 202 and the heating element 203. When the heating element 203 contracts, the heating element 203 will not hinder the movement of the conductive plug 5. Thus, the upper and lower pressures are transmitted to the synthesis column 1 through the conductive plug 5, the filling layer 3, and the liner tube 202. As a result, the synthesis column 1 is in a state of high temperature and high pressure, and the molecular structure inside it changes, and part of the graphite will be converted into diamond. The heat generated by the energization of the heating element 203 passes through the heat preservation member 204 to reduce the heat dissipation around the synthesis column 1.
