Description

Technical Field

[0001] The utility model relates to the technical field of cultured diamond production equipment, in particular to a graphite powder screening device for cultured diamond production. Background Art

[0002] Cultured diamonds are artificial diamonds that have the same physical and chemical properties as natural diamonds and are cheaper than natural diamonds. The production of cultured diamonds by high temperature and high pressure is a simulation of the formation process of natural diamonds. In the production of cultured diamonds by high temperature and high pressure, the synthetic block needs to be placed in a six-sided top press first. After a certain period of high temperature and high pressure synthesis, the carbon source is converted into diamonds, and they gather and grow on one side of the crystal bed in the catalyst to form gem-grade diamonds, that is, cultured diamonds. The cultured diamonds can then be separated through post-processing.

[0003] Graphite is a key material used as a carbon source and heating component in cultured diamond synthetic blocks. Before use, graphite powder needs to be screened through a graphite powder screening device.

[0004] After the traditional graphite powder screening device screens the graphite powder, when the screening plate is damaged, not only the function of the screening plate is lost, but also there is a problem that it is difficult to replace. Since the traditional screening plate is often fixed in the device and cannot be replaced separately, once it is damaged, the entire device needs to be repaired or replaced, which is troublesome and affects production efficiency. Therefore, a graphite powder screening device for cultured diamond production is proposed to solve the above problems. Utility Model Content

A driving assembly is provided on the right side of the upper end face of the support assembly, and the driving end of the driving assembly is in conflict with the lower end face of the mounting plate 15.

[0027] In the utility model, graphite powder for cultured diamond production is first poured through the feed pipe 2, the graphite powder enters the interior of the protective shell 1, and then falls on the screening component, and the driving component is started, and the elastic member is cooperated to drive the screening component to vibrate, so as to screen the graphite powder on the screening component, and the screened graphite powder will fall into the lower hopper 7, and the control valve 9 is opened, and the graphite powder will fall out through the discharge pipe 8, and the graphite powder that has not been screened will be discharged through the opening 12.

[0028] Furthermore, because the feed pipe 2 is installed on the left side of the upper end surface of the protective shell 1, the graphite powder that enters the protective shell 1 through the feed pipe 2 will fall on the left side of the upper end surface of the screening component.

[0029] In an optional embodiment, the screening assembly includes a screening plate mounting frame 16, alignment columns 19, bolts 20, a fixed plate 13, a side mounting block 14 and a screening plate 11, the front and rear end surfaces of the screening plate 11 are connected to the side mounting blocks 14, the front and rear side mounting blocks 14 are arranged in the grooves on the upper end surface of the screening plate mounting frame 16, the number of the fixing plates 13 is two and they are spaced apart on the upper end surfaces of the screening plate mounting frame 16 and the front and rear side mounting blocks 14, the number of the bolts 20 is multiple and they penetrate the fixing plate 13 and extend downward to the interior of the screening plate mounting frame 16, the screening plate mounting frame 16 and the bolts 20 are threadedly connected, the number of the alignment columns 19 is multiple and they are symmetrically distributed on the front and rear grooves on the upper end surface of the screening plate mounting frame 16, the multiple alignment columns 19 on the front and rear sides respectively penetrate the side mounting blocks 14 and the fixed plate 13 on the front and rear sides, and the left end surface of the screening plate mounting frame 16 is hinged to the inner wall of the left side of the protective shell 1.

[0030] It should be noted that when the screen plate 11 is damaged, first open the opening and closing components on both sides, use tools to rotate multiple bolts 20, remove the fixed plates 13 on both sides, and then pull out the side mounting blocks 14 on both sides from the grooves above the screen plate mounting frame 16, thereby driving the screen plate 11 to be removed; when installation is required, the side mounting blocks 14 will be installed in the grooves above the screen plate mounting frame 16, and the alignment columns 19 will pass through the side mounting blocks 14, so that they can be aligned and limited, and then the fixed plate 13 will be installed above the side mounting blocks 14 and the screen plate mounting frame 16, the alignment columns 19 will still pass through the fixed plate 13, and by rotating multiple bolts 20, the side mounting blocks 14 will be fixed to the screen plate mounting frame 16 through the fixed plate 13, thereby realizing the replacement of the screen plate 11.
