Description

Technical Field

[0001] This utility model relates to the field of synthetic diamond processing technology, specifically to a continuous cleaning and drying device for synthetic diamonds. Background Technology

[0002] The continuous cleaning and drying device for synthetic diamonds is an integrated equipment that uses an automated transfer mechanism to move the cleaning basket continuously between stations such as acid immersion, rinsing, neutralization, and drying, thereby achieving batch impurity removal, cleaning, and drying of synthetic diamonds.

[0003] Existing continuous cleaning and drying equipment for synthetic diamonds suffers from a critical problem of uneven cleaning and drying. Most existing devices employ fixed spraying or static immersion structures, leading to diamond particle accumulation in the cleaning basket. This results in insufficient contact between certain areas and the acid leaching solution, rinsing water, or drying airflow, causing excessive impurities and inconsistent dryness. This directly impacts the purity of the diamond product and the precision of subsequent processing, failing to meet the stringent uniformity requirements of high-end industrial sectors. Furthermore, the equipment lacks sufficient capacity to handle harmful gases generated during the cleaning and drying process. Acidic gases such as HCl and NO2 volatilized from the acid leaching process, as well as volatile organic compounds (VOCs) generated during the drying process, are often directly discharged through simple exhaust ventilation without targeted collection and filtration mechanisms. This not only deteriorates workshop air quality and harms the health of operators but also accelerates equipment corrosion and pollutes the surrounding environment. This fails to comply with current environmental regulations on industrial waste gas emissions and green production requirements, limiting the large-scale application of such equipment.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] This utility model discloses a continuous cleaning and drying device for synthetic diamonds.

[0020] This utility model provides a continuous cleaning and drying device for synthetic diamonds, as shown in Figures 1-5. It includes a base 1, and an acid immersion tank 2, a rinsing tank 3, a neutralization tank 4 and a drying tank 5 are fixedly connected to the top of the base 1 from left to right. U-shaped protective covers 6 are fixedly connected to both ends of the base 1. The positions of the U-shaped protective covers 6 correspond to the acid immersion tank 2, the rinsing tank 3, the neutralization tank 4 and the drying tank 5. An electric guide rail device 7 is fixedly connected to the top of the inner side wall of the U-shaped protective cover 6. A hydraulic rod 8 is fixedly connected to the moving execution end of the electric guide rail device 7. A rotating chamber 9 is fixedly connected to the bottom of the hydraulic rod 8. A cleaning basket cover 10 is rotatably connected to the bottom of the rotating chamber 9. A servo motor 11 is fixedly connected inside the cavity of the rotating chamber 9. The output rod of the servo motor 11 is fixedly connected to the top of the cleaning basket cover 10. A cleaning basket 12 is fixedly connected to the bottom via a limiting mechanism. An exhaust gas intake ring 13 is fixedly connected to the top of the inner wall of the acid leaching tank 2, rinsing tank 3, neutralization tank 4, and drying tank 5. A first connecting pipe 14 is fixedly connected to the inner wall of the U-shaped protective cover 6. The outlet end of each exhaust gas intake ring 13 is fixedly connected to the inlet of the first connecting pipe 14. The U-shaped protective cover 6... The side walls are fixed, and the base 1 provides stable support for each treatment tank and protective cover, ensuring the overall structural stability of the device and preventing component displacement due to vibration during operation. The acid leaching tank 2, rinsing tank 3, neutralization tank 4, and drying tank 5 sequentially achieve acid leaching for impurity removal, rinsing for acid removal, neutralization for pH adjustment, and drying for dehydration of synthetic diamonds, forming a continuous processing flow. Compared to traditional segmented operations, this significantly improves production efficiency. The U-shaped protective cover 6 creates a closed working space, preventing the diffusion of harmful gases and the entry of external impurities, ensuring a clean working environment. The electric guide rail device 7 drives the hydraulic rod 8 and the components below to move laterally, achieving automatic transfer of the cleaning basket between the tanks, reducing manual intervention. The hydraulic rod 8 can adjust the lifting height of the cleaning basket, ensuring accurate immersion or detachment from each treatment tank. To accommodate different pool depth requirements, a rotating chamber 9 provides installation space for a servo motor 11. The servo motor 11 drives the cleaning basket cover 10 and the cleaning basket 12 to rotate, ensuring that the diamonds fully contact the cleaning solution or hot airflow in the treatment pool. This avoids uneven cleaning and drying in certain areas, improving product purity and precision. The cleaning basket 12 holds the diamonds, and its perforated structure ensures smooth flow of the cleaning solution and hot airflow. A limiting mechanism ensures a secure connection between the cleaning basket and the cover, preventing it from falling off during transport. A waste gas suction ring 13 collects harmful gases (such as acid mist) generated in each pool from all directions. The waste gas is then discharged and treated through a first connecting pipe 14 in conjunction with a negative pressure fan 15, meeting environmental protection requirements and protecting the health of operators. This solves the problem of uneven cleaning and drying in traditional continuous cleaning and drying devices for synthetic diamonds, which affects production. The product lacks purity and precision, and there is no targeted treatment for harmful gases, failing to meet environmental protection and production requirements.

[0021] To ensure a secure connection between the washing basket and the cover, and for ease of assembly and disassembly, such as Figure 2 and 5As shown, the limiting mechanism includes a U-shaped positioning plate 16, a snap-fit ​​plate 17, a threaded limiting hole 18, and a threaded limiting rod 19. The bottom two ends of the cleaning basket cover 10 are fixedly connected to the U-shaped positioning plate 16, and the two end side walls of the cleaning basket 12 are fixedly connected to the snap-fit ​​plate 17. The snap-fit ​​plates 17 at both ends snap into the corresponding U-shaped positioning plates 16. The surfaces of the snap-fit ​​plates 17 at both ends and the U-shaped positioning plates 16 are provided with corresponding threaded limiting holes 18 and threaded limiting rods 19. By using the snap-fit ​​plates 17 and the U-shaped positioning plates 16 to snap into each other, the cleaning basket and the cover can be quickly positioned and installed. The threaded limiting rods 19 are used to lock the two together through the threaded limiting holes 18 to ensure a stable connection during transportation and rotation, and to prevent the cleaning basket from shaking or falling off.

[0022] In order to purify harmful waste gases and avoid environmental pollution, such as Figure 3 and 4 The filtration mechanism includes a second connecting pipe 20, a connecting tank 21, a 316L stainless steel filter screen 22, and a filter layer 23. The second connecting pipe 20 is fixedly connected to the top air inlet of the negative pressure fan 15. The connecting tank 21 is threadedly connected to the top of the second connecting pipe 20. The 316L stainless steel filter screen 22 is threadedly connected to the top of the inner side wall of the connecting tank 21. The filter layer 23 is snapped between the second connecting pipe 20 and the connecting tank 21. The 316L stainless steel filter screen 22 intercepts large particulate impurities (such as diamond fragments and dust) in the exhaust gas to prevent clogging of subsequent filter layers. The filter layer 23 adsorbs and purifies harmful components (such as acidic substances and volatile organic compounds) in the exhaust gas to ensure that the discharged gas meets environmental protection standards. The connecting tank 21 is threadedly connected to the second connecting pipe 20, which facilitates the replacement and maintenance of the filter screen and filter layer, reducing environmental treatment costs.

[0023] To improve the uniformity of cleaning and drying and ensure the treatment effect, such as Figure 1-3 The acid leaching tank is shown. 2. The rinsing tank 3, neutralization tank 4, and drying tank 5 are all cylindrical shells. Annular spray plates 24 are fixedly connected to the inner walls of the acid leaching tank 2, rinsing tank 3, and neutralization tank 4. Annular drying plates 25 are fixedly connected to the inner wall of the drying tank 5. An inlet connecting pipe 26 is fixedly connected to the side wall of each annular spray plate 24 and annular drying plate 25. Drain valves 27 are fixedly connected to the bottom outlets of the acid leaching tank 2, rinsing tank 3, neutralization tank 4, and drying tank 5. A discharge connecting pipe 28 is fixedly connected to the other end of each drain valve 27. The cylindrical shell design ensures even force distribution when the cleaning basket rotates, preventing uneven distribution of chemicals or hot air. The annular spray plate 24, connected to the chemical solution via the inlet connecting pipe 26, sprays the chemical solution onto the cleaning basket from all directions, enhancing the effects of acid leaching, rinsing, and neutralization, and reducing cleaning dead zones. The annular drying plate 25, connected to the hot air, achieves 360° uniform drying, preventing localized moisture absorption of the diamonds. The drain valve 27, in conjunction with the discharge connecting pipe 28, facilitates the rapid discharge and recycling of waste liquid from each pool, improving operational continuity.

[0024] In order to achieve deep purification of waste gas and improve environmental protection, such as Figure 4 As shown, the filter layer 23 includes a polypropylene (PP) meltblown fabric pre-filter layer, an activated carbon adsorption layer, and a glass fiber high-efficiency filter layer. The polypropylene (PP) meltblown fabric pre-filter layer, the activated carbon adsorption layer, and the glass fiber high-efficiency filter layer are sequentially snapped between the connecting tank 21 and the second connecting pipe 20 from the outside to the inside. The polypropylene (PP) meltblown fabric pre-filter layer filters fine dust in the exhaust gas to prevent clogging of the activated carbon adsorption layer. The activated carbon adsorption layer adsorbs acidic substances and organic pollutants in the exhaust gas to reduce the content of harmful components. The glass fiber high-efficiency filter layer further filters fine particles and residual harmful gases.

[0025] To enhance the corrosion resistance and durability of equipment, such as Figure 1 , 2 As shown in Figures 3 and 5, a display controller 29 is fixedly connected to one side wall of the base 1, and the acid leaching tank 2, rinsing tank 3, and intermediate rinsing tank are also present. The inner walls of the washing tank 4 and the drying tank 5 are sequentially coated with a polytetrafluoroethylene (PTFE) anti-seepage coating, an epoxy zinc-rich primer, and a fluorocarbon topcoat composite coating. The inner walls of the exhaust gas intake ring 13 and the connecting pipe 14 are coated with a ceramic-based composite coating. The outer surface and inner wall of the washing basket 12 are coated with an aluminum nitride ceramic coating. The electric guide rail, hydraulic rod, servo motor, and other components are centrally controlled by the display controller 29 to achieve automated operation, reduce human operation errors, and improve processing accuracy. The PTFE anti-seepage coating prevents the chemical solution from penetrating and corroding the tank body. The epoxy zinc-rich primer enhances the rust prevention ability, and the fluorocarbon topcoat improves the surface wear resistance and extends the service life of the tank body. The ceramic-based composite coating enhances the corrosion resistance of the exhaust gas intake ring and the connecting pipe, avoiding acid mist corrosion. The aluminum nitride ceramic coating improves the high temperature resistance and wear resistance of the washing basket, making it suitable for drying and acid immersion environments.
