[0002] Diamond-ceramic composite abrasives possess isotropic properties, abundant cutting edges, and high self-sharpening characteristics, making them widely used in the grinding and polishing processes of sapphire wafers, silicon carbide wafers, and ceramic materials. Driven by market demand, the demand for diamond-ceramic composite abrasives is increasing rapidly. However, the manufacturing process inevitably produces a portion of abrasive that is unsuitable for current market applications. This unsatisfactory abrasive becomes stockpiled and ineffective for diamond-ceramic composite abrasive manufacturers. Therefore, addressing this unsatisfactory abrasive is crucial. Recycling and reusing the diamonds in this waste abrasive is of great significance for saving production costs and promoting resource recycling.

[0024] The basic concept of the reaction vessel device of the diamond extraction equipment in abrasives of this utility model is to directly heat the solid alkali material at high temperature in the reaction vessel to turn it into a molten liquid and react it with the abrasive. With the help of the spray head 26, the temperature is cooled and water is injected, which can effectively shorten the reaction time, improve the alkali dissolution efficiency, and facilitate the centralized and efficient treatment of large batches of diamond ceramic composite abrasive waste.

[0025] The following detailed description is provided in conjunction with specific embodiments. Embodiments of the diamond extraction device in abrasives according to this utility model: The diamond extraction equipment in this embodiment is an automated device for extracting single-crystal diamonds from waste diamond-ceramic composite abrasives. The equipment includes a reaction vessel and a rinsing device. The reaction vessel is used for alkaline dissolution of the diamond-ceramic composite abrasive, and the rinsing device is used to receive the mixture discharged from the reaction vessel and perform rinsing, as well as acid dissolution followed by rinsing, thereby obtaining pure diamonds.

[0026] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4The reactor assembly of this equipment includes a frame and a reactor body 4 mounted on the frame. A vacuum feeder 2 is installed on the frame, located above the reactor body 4. Its inlet is connected to a feed hopper 7 via a pipe, and its outlet is connected to the reactor body 4 via a pipe. The opening and closing of the vacuum feeder 2 is controlled by a control panel 5. There are two feed hoppers 7, one for abrasive and one for alkali, located on the ground. The pipe connecting the feed hoppers 7 and the vacuum feeder 2 is a feed connection pipe 16. The vacuum feeder 2 has an automatic quantitative feeding function. The vacuum feeding system avoids dust splashing and pollution caused by manual powder addition, achieving dust-free feeding. Simultaneously, the vacuum feeder 2 enables quantitative feeding, reducing the harm of dust to personnel, saving labor costs, and improving efficiency.

[0027] The reactor body 4 includes a vessel body 28 and a heating device. The vessel body 28 is used to hold diamond ceramic composite abrasive and solid alkali material. The discharge port of the vacuum feeder 2 is connected to the inner cavity of the vessel body 28 through a pipeline. The heating device is matched with the vessel body 28. The heating device is located outside the vessel body 28 and is used to heat the alkali material inside the vessel body 28 into a molten liquid state. A water spray pipeline is installed on the vessel body 28. The water spray pipeline includes a spray head 26 that extends into the vessel body 28. The spray head 26 is used to spray water mist onto the material inside the vessel body 28 to cool it down and disperse the material in the water.

[0028] By equipping the reactor body 28 with a heating device and a spray head 26, and ensuring that the heating device transforms the alkali material inside the reactor body 28 into a molten liquid, the molten alkali material can react efficiently with the diamond ceramic composite abrasive. After the reaction, the spray head 26 can be used to spray water mist onto the material, which can cool the material and increase the cooling rate. Moreover, water can be added while the material is still at a high temperature, and the mist droplets will not react violently with the material to cause danger. As the mist droplets are continuously added, the material in the reactor is gradually cooled and dispersed in the water. The mixture of material dispersed in the water can directly enter the subsequent rinsing device without waiting for the natural cooling process. Furthermore, the residual heat can be used to accelerate dissolution and improve the alkali dissolution efficiency, making it suitable for the centralized and efficient treatment of large quantities of diamond ceramic composite abrasive waste.

[0029] The heating device includes an electromagnetic heating coil 20 installed on the outer wall of the vessel body 28. The electromagnetic heating coil 20 is arranged around the outer circumference of the vessel body 28, which forms the inner tank of the reactor. The electromagnetic heating coil 20 is located around the vessel body 28, and a reactor insulation layer 27 is provided around the electromagnetic heating coil 20. Electromagnetic heating offers a fast heating rate, low energy consumption, and a high maximum temperature. In other embodiments, resistance wire heating can also be used when the resistance wire meets the temperature requirements.

[0030] The reactor body 4 features a multi-layer design, with an inner reactor barrel, a middle asbestos insulation layer, and an outer reactor shell. The reactor body 28 is made of stainless steel; glass is unsuitable for alkaline treatment of powders. The reactor body 28 is a composite cylinder, with an outer layer of 430 stainless steel and an inner nickel-plated layer. The 430 stainless steel serves as the electromagnetic heating layer, while the nickel plating layer provides corrosion resistance. Nickel plating on the inner wall of the reactor body 28 enhances the corrosion resistance of the stainless steel reactor.

[0031] A lid is provided at the top of the vessel body 28 to form a relatively closed cavity inside the vessel body 28. A temperature sensor 19 is inserted through the lid into the vessel body 28 near the bottom and is connected to the control panel 5 for signal detection of the material temperature. A reactor inlet 3 is provided on the lid. A negative pressure pipeline 8 for extracting waste gas from the vessel body 28 is installed on the lid.

[0032] The reactor apparatus includes a stirring mechanism mounted on a frame and positioned centrally above the reactor body 4. The stirring mechanism comprises a reactor stirring frame 21 extending into the reactor body 28 for stirring materials, a rotary drive mechanism for rotating the stirring frame, and a lifting drive mechanism for raising and lowering the stirring frame. The reactor stirring frame 21 includes a central shaft and a stirring rod fixed to the lower end of the central shaft, and is made of stainless steel. The lifting drive mechanism uses a reactor pneumatic motor displacement cylinder 1, and the rotary drive mechanism uses a reactor stirring pneumatic motor 18, which is connected to the central shaft of the stirring frame. The stirring power equipment is a pneumatic motor, whose start and stop are controlled via a control panel 5. Using a pneumatic motor reduces the risk of aging and damage due to high humidity inside the grading equipment.

[0033] When stirring is required, the telescopic rod of the displacement cylinder 1 of the reactor pneumatic motor descends, simultaneously lowering the reactor stirring pneumatic motor 18 and the reactor stirring frame 21. After descending, the pneumatic motor starts rotating, causing the stirring frame to rotate and stir. When stirring is not required, the pneumatic motor shuts off, the cylinder rises, and the pneumatic motor and stirring frame rise, without affecting material feeding and improving service life. The cylinder lifting and the pneumatic motor opening and closing are both controlled via the control panel 5. In other embodiments, a lifting drive mechanism may not be provided.

[0034] The spray head 26 is located on one side of the axis of the vessel body 28, near the top inner wall of the vessel body 28, and is tilted downwards towards the axis of the vessel body 28. The water spray pipeline includes a connecting pipe, which is a bent pipe. One end extends downwards through the vessel cover into the vessel body 28 and is connected to the spray head 26. The other end forms the reactor water inlet 9 to connect to an external water inlet pipe. The spray head 26, also known as the spray nozzle, is located at the top of the inner wall of the reactor, and the opening and closing of the pipeline is controlled by the control panel 5. The spray atomization method is used to dilute the reacted materials, avoiding the difficulty of dissolving the materials in water after natural cooling. In other embodiments, the spray head can also be located near the center of the vessel cover.

[0035] The bottom of the reactor body 28 has a conical structure, and a discharge port is set at the center of the bottom of the reactor body 28. A discharge valve is installed at the discharge port. In this embodiment, a pneumatic upward-expanding discharge valve 6 is used. This pneumatic upward-expanding butterfly valve is located at the bottom of the reactor, and its opening and closing are controlled by the control panel 5. This can ensure that there is no dead corner accumulation of material in the reactor during the reaction, avoiding incomplete reaction. At the same time, it has an automatic control function, realizing automated discharge. In other embodiments, other types of shut-off valves can also be used.

[0036] A rinsing device is arranged side-by-side on one side of the reactor apparatus. The rinsing device includes a frame, a washing tank 15, and various pipelines. The washing tank 15 of the rinsing device is connected to the discharge valve at the bottom of the reactor body 28 through a washing connection pipeline 17. The washing connection pipeline 17 leads to the top of the washing tank 15. The washing tank 15 is made of PP (polypropylene), preferably HDPE (high-density polyethylene), which has good acid and alkali resistance.

[0037] The washing tank 15 of the rinsing device is equipped with a cover plate on top. An air inlet slit 14 is provided at the junction of the washing tank 15 and the cover plate. A negative pressure pipeline 12 for extracting waste gas from the washing tank 15 is installed on the cover plate. The rinsing device also includes an acid injection pipeline 22, a water injection pipeline 24, and a liquid extraction pipeline 13, which extends into the washing tank 15 near the bottom. Rinsing after alkali dissolution, rinsing after acid dissolution, and rinsing after acid dissolution are all performed in the same washing tank 15, improving efficiency.

[0038] The rinsing device includes a stirring mechanism mounted on a frame and located directly above the washing tank 15. The stirring mechanism comprises a washing tank stirring frame 25 extending into the washing tank 15 for stirring the material, a rotary drive mechanism for rotating the washing tank stirring frame 25, and a lifting drive mechanism for raising and lowering the washing tank stirring frame 25. The rotary drive mechanism uses a washing tank stirring pneumatic motor 23, and the lifting drive mechanism uses a washing tank pneumatic motor displacement cylinder 10. The stirring frame uses a polytetrafluoroethylene (PTFE) stirring rod. The working principle of the stirring mechanism in the rinsing device is the same as that of the stirring mechanism in the reaction vessel device.

[0039] The washing tank's liquid extraction pipeline 13 is equipped with a liquid extraction pipe displacement cylinder 11. The pipeline that needs to move is a flexible hose, and the liquid extraction pipeline is used to extract the upper layer of liquid. When liquid extraction is required, the liquid extraction pipe displacement cylinder 11 lowers the extraction port of the washing tank's liquid extraction pipeline 13 to below the liquid level inside the washing tank 15. The washing tank's liquid extraction pipeline 13 is connected to a diaphragm pump (not shown in the figure). When the diaphragm pump is turned on, the washing tank's liquid extraction pipeline 13 begins to extract the solution in the washing tank 15. After the extraction is completed, the cylinder drives the liquid extraction pipeline to rise. The cylinder's raising and lowering and the opening and closing of the liquid extraction pipeline are both controlled by the control panel 5.

[0040] Control panel 5 is fixed to the frame and integrates multiple control circuits, using programs to control various modules of the equipment. As the central control system, control panel 5, through PLC programming, can realize operations such as automatic feeding, automatic alkali boiling and dilution, automatic solution extraction, automatic water replenishment, and automatic acid injection, achieving automated cleaning of the materials after the reaction.

[0041] During use, alkali powder, diamond ceramic composite abrasive waste, or other materials (the number of feeding hoppers is unlimited) are loaded into the feeding hopper 7. Alkali powder is solid alkali. After loading, the vacuum feeder 2 is turned on, and the material in the feeding hopper 7 is quantitatively extracted into the reactor body 28 through the feeding connection pipe 16 between the vacuum feeder 2 and the feeding hopper 7. After the powder is added, the electromagnetic heating coil 20 is energized to start heating the reactor body 28. The temperature can be obtained through the temperature sensor 19 and displayed on the control panel 5. At the same time as heating, the reactor negative pressure pipeline... 8. When the reactor is turned on, the exhaust gas is continuously extracted from the reactor. After heating to the set temperature (at this time, the alkali powder melts into a liquid state at high temperature), the reactor pneumatic motor displacement cylinder 1 drives the reactor stirring pneumatic motor 18 and the reactor stirring frame 21 connected to the motor to fall and start stirring. After heating and stirring for the set time, the heating stops and the reactor water inlet 9 is connected, so that the spray head 26 starts to spray. The spray volume can be controlled by the control panel 5. As the mist water droplets are continuously added, the material in the reactor gradually cools down and disperses in the water. When the temperature sensor 19 detects a temperature below 60℃, the pneumatic upward discharge valve 6 at the bottom of the reactor opens. The mixed liquid in the reactor flows into the washing tank 15 through the washing connection pipe 17 between the reactor and the washing tank 15. At the same time as discharge, the negative pressure pipe 12 of the washing tank is opened to draw exhaust gas from the washing tank 15. After the mixed material in the reactor has completely flowed into the washing tank 15, the pneumatic motor displacement cylinder 10 of the washing tank drives the washing tank stirring pneumatic motor 23 and the washing tank stirring frame 25 to fall and start stirring. The stirring time is controlled by the control panel 5. Adjustable. After stirring, the mixture is allowed to stand for the set time. After standing, the suction pipe displacement cylinder 11 drives the washing tank suction pipe 13 to fall and begin to extract the upper layer solution after standing. After extraction, the suction pipe displacement cylinder 11 drives the washing tank suction pipe 13 to rise. After extraction, the washing tank water injection pipe 24 is opened. The upper limit of water injection is controlled by the float solenoid valve (not shown in the figure). After water injection, the stirring and upper layer solution extraction actions are repeated. The mixture is rinsed multiple times until the real-time pH meter (not shown in the figure) measures less than 9. Then, the upper layer solution after standing is extracted. Then, through the linkage control of the float solenoid valve and the water injection pipeline 24 of the washing tank, water is injected into the washing tank 15 to half its height. After the injection is completed, the washing tank 15 is stirred and the acid injection pipeline 22 of the washing tank is opened to start injecting acid into the washing tank 15. After the real-time pH meter reading is less than 2, the acid injection pipeline 22 of the washing tank is closed. Then the stirring of the washing tank 15 stops and it begins to stand. After the standing is completed, the displacement cylinder 11 of the extraction pipe drives the liquid extraction pipeline 13 of the washing tank to fall and start to extract the upper layer solution after standing. After the extraction is completed, water is injected for rinsing until the real-time pH meter reading is above 6, and then the rinsing is completed. At this time, the diamond obtained in the washing tank 15 is pure diamond.

[0042] This equipment significantly improves operational convenience, increases production efficiency, and reduces labor costs by processing waste generated during the production of diamond-ceramic composite abrasives. The rinsing unit integrates alkali washing, acid addition, and acid washing. The electromagnetically heated reactor enables rapid high-temperature reactions and automatic rinsing of the reacted materials. A vacuum feeder ensures dust-free feeding. The equipment's internal drive components are primarily pneumatic, avoiding the aging issues associated with high moisture content in the grading environment.
