Description

Technical Field

[0001] This utility model relates to the field of synthetic diamond technology, and more specifically to a device for removing impurities from synthetic diamonds. Background Technology

[0002] In the field of materials science, synthetic diamonds, with their superior hardness, wear resistance, and good thermal conductivity, have shown broad application prospects in various fields such as industrial cutting, grinding, optical windows, and semiconductor substrates. However, during the production of synthetic diamonds, due to limitations in the synthesis process, various impurities are inevitably introduced into the crystal or onto its surface, such as metal inclusions, amorphous carbon phases, graphite residues, and other mineral impurities. The presence of these impurities not only significantly reduces the quality of synthetic diamonds, affecting their mechanical properties, optical transmittance, and electrical properties, but also severely restricts their performance in high-end applications. Therefore, efficiently and accurately removing impurities from synthetic diamonds has become a key step in improving product quality and market competitiveness.

[0003] As shown in the prior art published in CN221832791U, although this prior art achieves the function of facilitating vibration through the setting of a base, drive motor, drive shaft, transmission mechanism, driven shaft, extrusion block, support rod, return spring, movable block, connecting block, movable rod, filter plate, and guide plate, thereby improving the efficiency of impurity removal and facilitating the purification and processing of synthetic diamonds, meeting people's work needs, it is worthy of promotion and use. However, the structure of the vibrating filter plate in this prior art is relatively complex, requiring the cooperation of a drive motor, drive shaft, transmission mechanism, driven shaft, extrusion block, support rod, return spring, movable block, connecting block, and movable rod, which increases manufacturing costs and subsequent maintenance costs, and the vibration is prone to insufficient separation. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a synthetic diamond impurity removal device. A servo motor drives a spiral assembly to rotate, which transports the material into a filter cylinder. The filter cylinder then removes impurities from the material. Simultaneously, the forward and reverse rotation of the spiral assembly allows for multiple reciprocating screenings of the material, improving the impurity removal effect and preventing material accumulation that hinders thorough screening. Furthermore, the overall structure is simple, effectively reducing manufacturing and maintenance costs, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a synthetic diamond impurity removal device, comprising a base, an outer cylinder at the top of the base, a sealing cylinder fixedly connected to the front side of the top of the outer cylinder, and a filter cylinder extending into the interior of the outer cylinder installed at the rear end of the sealing cylinder, wherein the cross sections of the outer cylinder, the sealing cylinder, and the filter cylinder are all inclined. The encapsulation cylinder is equipped with a spiral assembly that is movably connected via a rotating shaft, and a feed pipe is fixedly connected to the top front end of the encapsulation cylinder.

[0006] In a preferred embodiment, the filter cartridge is provided with a sealing plate at the rear end, and electric push rods are installed on the front sides of both ends of the sealing plate. The front end of the electric push rod is fixed to the rear side of the outer cylinder. The sealing plate seals the filter cartridge to prevent leakage of material in the filter cartridge. Then, the extension of the electric push rod pushes the sealing plate to separate from the filter cartridge, thereby facilitating the release of material in the filter cartridge and achieving the effect of removing impurities from the material.

[0007] In a preferred embodiment, a servo motor is installed at the front end of the packaging cylinder. The output shaft of the servo motor passes through the packaging cylinder and is fixed together with the rotating shaft on the spiral bar. Through the connection between the output shaft of the servo motor and the spiral bar, the servo motor can drive the spiral bar to rotate, thereby enabling the spiral bar to reciprocate and transport materials, improving the efficiency of material removal.

[0008] In a preferred embodiment, a fixing frame is fitted around the front end of the outer cylinder. The bottom end of the fixing frame is fixed to the top of the base. The fixing frame supports and limits the outer cylinder, ensuring its stability and preventing it from tilting or collapsing.

[0009] In a preferred embodiment, the base has a collection box at the top of its rear end, and the collection box has a first material trough and a second material trough at its top, with the first material trough located in front of the second material trough. The rear end of the filter cartridge is located at the top of the second material trough, and the outer cylinder is located at the top of the first material trough. Materials and debris are classified and collected through the first and second material troughs in the collection box, thereby improving the convenience of collecting materials and debris.

[0010] In a preferred embodiment, the base has multiple mounting holes at its top, which are evenly spaced apart. The mounting holes can be used to fix and limit the base, thereby ensuring the support strength of the base and the operational stability of the outer cylinder and filter cylinder on the base.

[0011] The technical effects and advantages of this utility model are as follows: The spiral column is driven to rotate by a servo motor. The spiral column transports the material into the filter cartridge, where the filter cartridge removes impurities from the material. The forward and reverse rotation of the spiral column allows for multiple reciprocating screenings of the material, improving the removal of impurities and preventing material accumulation that would hinder screening. The overall structure is simple, effectively reducing construction and maintenance costs. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Refer to the instruction manual appendix Figure 1-5 This utility model provides a device for removing impurities from synthetic diamonds, including a base 1, an outer cylinder 2 on the top of the base 1, a sealing cylinder 3 fixedly connected to the front side of the top of the outer cylinder 2, a filter cylinder 4 extending into the outer cylinder 2 installed at the rear end of the sealing cylinder 3, and the cross sections of the outer cylinder 2, the sealing cylinder 3 and the filter cylinder 4 are all inclined; a spiral assembly 5 is installed inside the sealing cylinder 3 and movably connected to it via a rotating shaft, and a feed pipe 6 is fixedly connected to the top of the front end of the sealing cylinder 3.

[0016] When using the filter cartridge 4 inside the outer cylinder 2 to remove impurities from synthetic diamonds, the operator first feeds the material through the feed pipe 6 to the spiral assembly 5 inside the encapsulation cylinder 3. Then, the spiral assembly 5 guides the material into the filter cartridge 4. When the material is fed into the filter cartridge 4, the filter cartridge 4 screens the impurities into the outer cylinder 2, thereby achieving the screening of the material and impurities. Furthermore, by rotating the spiral assembly 5 in both directions, the material can be screened repeatedly, which can effectively improve the impurity removal effect of the material.

[0017] To ensure the operational efficiency of the spiral array 5, a servo motor 9 is installed at the front end of the encapsulation cylinder 3. The output shaft of the servo motor 9 passes through the encapsulation cylinder 3 and is fixed together with the rotating shaft on the spiral array 5. In this way, the spiral array 5 can be driven to rotate by the servo motor 9, and the power driven by the servo motor 9 can effectively ensure and improve the operational stability and efficiency of the spiral array 5.

[0018] Meanwhile, to ensure the stability of the outer cylinder 2, it is necessary to provide limiting support for the outer cylinder 2. Therefore, a fixing frame 10 is fitted onto the front end of the outer cylinder 2, and the bottom end of the fixing frame 10 is fixed to the top of the base 1. In this way, the fixing frame 10 can provide limiting support for the outer cylinder 2, ensuring the stability of the outer cylinder 2 and ensuring that the outer cylinder 2 can effectively support the filter cylinder 4, preventing the outer cylinder 2 from tilting or collapsing.

[0019] After material screening, the screened impurities and materials need to be classified and collected. A collection box 11 is provided at the top rear end of the base 1. The top of the collection box 11 has a first material trough 12 and a second material trough 13, with the first material trough 12 located in front of the second material trough 13. The rear end of the filter cartridge 4 is located on top of the second material trough 13, and the outer cylinder 2 is located on top of the first material trough 12. This correspondence between the first material trough 12 and the outer cylinder 2, and the second material trough 13 and the filter cartridge 4, allows the first material trough 12 and the second material trough 13 on the collection box 11 to collect impurities from the outer cylinder 2 and materials from the filter cartridge 4, respectively, thereby improving the impurity removal effect.

[0020] Before the collection box 11 can classify and collect materials and debris, the filter cartridge 4 needs to be opened. A sealing plate 7 is then installed at the rear end of the filter cartridge 4. Electric push rods 8 are installed on the front sides of both ends of the sealing plate 7, and the front ends of the electric push rods 8 are fixed to the rear side of the outer cylinder 2. Thus, the extension of the electric push rods 8 can push the sealing plate 7 outwards, causing the sealing plate 7 to be misaligned with the filter cartridge 4. This allows the material inside the filter cartridge 4 to fall into the second material trough 13 inside the collection box 11, improving the material collection efficiency.

[0021] To ensure the operational stability of the equipment on the base 1, the stability of the base 1 itself must be guaranteed. Therefore, multiple mounting holes 14 are provided on the top of the base 1, and these mounting holes 14 are evenly spaced apart. By connecting the fastening device to the mounting holes 14, the base 1 can be fixed in place, thereby ensuring the operational stability of the outer cylinder 2, filter cylinder 4, and other equipment on the base 1.

[0022] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
