Description

Technical Field

[0001] The utility model relates to the technical field of artificial diamond superhard materials, in particular to a synthetic block device filled with high-density materials in multiple directions. Background Art

[0002] At present, the synthesis of superhard materials such as artificial diamond mainly relies on high-temperature and high-pressure synthesis in a press composed of domestically produced six-sided top hinged beams. Low voltage (less than 5V) and high current (1000-3000A) make the high-temperature resistant graphite heater itself generate heat and thus provide a high-temperature growth environment; according to Pascal's principle, small pressure on a large cross-section is converted into large pressure on a small cross-section. During the synthesis pressurization process, 6 top hammers squeeze the talc block to form a sealing edge for sealing, so that high pressure is generated inside the cavity of the synthetic block.

[0003] Synthetic diamonds are highly dependent on stable pressure, and the required high pressure is completely dependent on the high pressure generated by the hydraulic system of the six-sided top press. With the continuous maturity of diamond synthesis technology, the production efficiency and production capacity of artificial diamond products have been greatly improved. However, the fatigue life of the six-sided top press is fixed. The existing six-sided top press equipment of some companies has been in operation for a long time. In the day-to-day high-pressure synthesis, different degrees of aging have occurred, the pressure transmission efficiency is low, and the pressure loss is large. The machine is continuously subjected to cyclic loads and has problems such as internal leakage and frequent pressure replenishment. According to statistics, a medium-sized superhard material company with 200 presses has an average of 40 machines shut down for maintenance due to internal leakage, pressure replenishment and other faults each year, with an average shutdown of 3-15 days each time. The loss of a press shutdown for one day is as high as 1,500 yuan, and the labor cost spent on equipment maintenance and the economic loss caused by equipment shutdown is as high as 180,000 to 900,000 yuan a year.

[0004] Therefore, there is an urgent need for a synthetic block device filled with high-density materials in all directions that can improve the pressure transmission efficiency, effectively reduce the set pressure, reduce the risk of internal leakage and the frequency of beam dismantling and maintenance. Utility Model Content

[0005] The purpose of the utility model is to provide a synthetic block device filled with high-density materials in multiple directions. Under the premise of meeting the stable growth of crystals, the pressure can be reduced by 8-15 Mpa on the basis of the original pressure, which can directly increase the life of the six-sided top press, reduce the number of beam dismantling and maintenance times, save manpower and material costs, and provide favorable conditions for enterprises to achieve cost reduction and efficiency improvement.

[0006] The utility model adopts the following technical solutions:

[0007] A synthetic block device filled with high-density materials in multiple directions, comprising two outer frames composed of pyrophyllite, each of the outer frames being provided with a filling slot on the plane, the filling slots being filled with a filling layer, wherein the filling layers in at least one group of symmetrical filling slots are conductive; and a dolomite bushing is provided in the outer frame.

[0008] Preferably, the filling slot is arranged in the middle of each plane of the external frame.

[0009] Preferably, the filling slots are symmetrically arranged in pairs on the plane of the external frame.

[0010] Preferably, the number of the filling slots is four or six.

[0011] Preferably, the thickness of the filling layer is not greater than the thickness of the filling groove.

[0012] Preferably, the thickness of the filling groove is 1-10 mm.

[0013] Preferably, the filling slot is circular or square in shape.

[0014] Preferably, the dolomite bushing is provided with a through hole extending vertically therethrough.

[0015] Preferably, after the dolomite bushing is arranged in the external frame, each surface thereof is in contact with the filling layer.

[0016] Compared with the prior art, the utility model has the following beneficial effects: by arranging filling slots in multiple directions on the external frame, the utility model can arrange various types of filling layers in the filling slots, so as to produce better pressure transmission performance during the working process. In cooperation with the dolomite bushing, the pressure transmission efficiency is effectively improved, thereby reducing the set pressure of the six-sided top press in the process of synthesizing superhard materials such as artificial diamonds, significantly reducing the frequency of pressure drop of the press, significantly improving the phenomenon of internal leakage and frequent pressure replenishment of small pumps, and making the machine run more smoothly during the synthesis process, thereby improving product quality. In addition, the service life of the six-sided top press can be directly increased, the number of times of beam dismantling and maintenance can be reduced, the cost of manpower and material resources can be saved, and energy consumption can be reduced, thereby helping enterprises to reduce costs and increase efficiency.

[0021] The following is a clear and complete description of the present invention in conjunction with the accompanying drawings and embodiments:

[0022] like Figures 1 to 4 As shown, the utility model discloses a multi-directional high-density material-filled synthetic block device, comprising two outer frames 1 composed of pyrophyllite, each outer frame 1 is provided with a filling slot 2 on the plane, and the filling slot 2 is filled with a filling layer 3, and the filling layer 3 is a high-density filling material, which is usually a high-density ceramic material (such as alumina, zirconium oxide and other ceramic materials) or a high-temperature resistant and high-hardness metal material (such as copper, high-temperature alloy steel, hard alloy, etc.), wherein at least one group of the filling layers 3 in the filling slots 2 is conductive, so the filling layers 3 of the group are usually high-temperature resistant. High-hardness metal materials (such as copper, high-temperature alloy steel, cemented carbide, etc.) are used to make the symmetrical conductive filling layers 3 contact with the powered heating hammer for heating during operation; the remaining filling layers 3 only need to bear the pressure transmission function, so they can be flexibly selected from the above materials; a dolomite bushing 4 is arranged in the external frame 1, and a through hole 5 is arranged inside the dolomite bushing 4, which is connected vertically, and the through hole 5 is used to fill the material for synthetic diamond large single crystals, such as placing conductive steel rings, heated carbon sheets, heated carbon tubes, carbon sources, catalysts, crystal seeds and other conventional materials.

[0023] Furthermore, in this embodiment, the filling slots 2 are arranged in the middle of each plane of the external frame 1 to ensure uniform force. The filling slots 2 are symmetrically arranged in pairs on the plane of the external frame 1. Figure 4 As shown, in this embodiment, the number of filling slots 2 is four or six to form a four-orientation or six-orientation synthesis block, thereby meeting different synthesis requirements.

[0024] In addition, the thickness of the filling layer 3 in this embodiment is not greater than the thickness of the filling slot 2. Preferably, the thickness of the filling layer 3 is less than the thickness of the filling slot 2. The remaining thickness difference is compensated by the size of the dolomite bushing 4, so that after the dolomite bushing 4 is installed inside the external frame 1, each surface is in contact with the corresponding filling layer 3, which can ensure both the pressure transmission efficiency and sufficient internal growth space. The thickness of the filling slot 2 is 1-10mm, and the corresponding thickness is selected within this range. When filling, the filling layer 3 and the dolomite bushing 4 complement each other to complete the filling of the filling slot 2; for example, when the internal height of the filling slot 2 is 8mm, the thickness of the filling layer 3 placed inside the filling slot 2 is 4mm, and the protruding part of the corresponding dolomite bushing 4 is 4mm. In addition, in this embodiment, the shape of the filling slot 2 can be a variety of shapes, preferably set to be circular or square, with a simple structure and easy to manufacture, and convenient for the installation and filling of the filling layer 3.

[0025] The utility model installs the filling layer 3 into the filling slot 2, and then installs the dolomite bushing 4 into the external frame 1, and places the material for synthesizing large single crystal diamond in the dolomite bushing 4, and then the synthetic block formed by combining the two parts of the talc frame is placed in the six-sided top press for synthesis; by optimizing the setting of the external frame 1, the pressure transmission efficiency of the synthetic block is effectively improved, and the set pressure of the six-sided top press in the process of synthesizing superhard materials such as artificial diamond is reduced. The pressure is reduced by 8-15Mpa on the original basis, the frequency of pressure drop of the press is significantly reduced, the phenomenon of internal leakage and frequent pressure replenishment of small pumps is significantly improved, and the machine runs more smoothly during the synthesis process, thereby improving product quality. In addition, the present invention can increase the life of the six-sided top press, reduce the number of times of beam dismantling and maintenance, save manpower and material costs, and reduce energy consumption, thereby helping enterprises to achieve cost reduction and efficiency improvement, and has strong practicality.
