The turbidity sensor detects the concentration of the upper clear liquid in real time during the sedimentation process, and automatically triggers the extraction operation when the set concentration value is reached, ensuring that the concentration of the extracted slurry meets the process requirements. The radar level sensor accurately monitors the liquid level changes in the sedimentation tank, preventing excessive extraction that would cause high concentrations or coarse particles to be carried out from the bottom, thus ensuring the accuracy of classification. At the same time, after each extraction, water is automatically replenished and the stirring device is started for redispersion, realizing a cyclic operation mode, which significantly improves the efficiency and continuity of slurry classification and avoids the production interruption and resource waste caused by traditional intermittent operation.

[0016] 2. This utility model separates the sedimentation mechanism and the material extraction mechanism on two sides, achieving efficient connection through multiple surrounding conveying hoses. This optimizes space utilization and improves the uniformity and stability of material extraction. The sedimentation mechanism is equipped with a bottom stirring head and blades to ensure that the slurry is fully and evenly dispersed, avoiding particle agglomeration. During extraction, a top-bent pipe with the liquid inlet facing upwards is used to cleverly avoid the high-concentration sediment layer at the bottom, preventing coarse particles from mixing in and ensuring the consistency of the extracted slurry particle size. The material extraction mechanism uses vacuum negative pressure suction to achieve a stable, shear-free conveying method, reducing damage to micro powder particles. The transfer tank, equipped with a solenoid valve and funnel structure, facilitates centralized storage and controllable discharge, meeting the slurry supply needs of different subsequent processes. The overall system has a high degree of automation, with unified and coordinated operation by a control module, improving operational safety and process repeatability. It is suitable for the large-scale classification and processing of high-precision diamond micro powder. Attached Figure Description

[0029] Furthermore, a sealing cover 204 is installed on the top of the settling tank 201. A radar level sensor 207 and a water inlet valve 203 are installed on the top of the sealing cover 204. A lifting plate 212 is provided on the top of the sealing cover 204. A liquid extraction pipe 205 is installed around the lifting plate 212. One end of the liquid extraction pipe 205 is connected to the delivery hose 4. The other end of the liquid extraction pipe 205 extends through the sealing cover 204 and is connected to a bend pipe 209. The liquid inlet end of the bend pipe 209 is set upward and is located in the detection area of ​​the turbidity sensor 202.

[0030] Furthermore, a drive device 206 is fixedly installed at the top center of the lifting plate 212. The output shaft of the drive device 206 passes through the sealing cover 204 and is equipped with a stirring rod 208. A stirring head 210 is installed at the bottom of the stirring rod 208. The stirring head 210 is located at the bottom of the inner cavity of the settling tank 201, and stirring blades 211 are installed around the surface of the stirring head 210.

[0031] Furthermore, the drive unit 206 is an electric motor.

[0032] Furthermore, the material extraction mechanism 3 includes a transfer tank 301 and a vacuum pump 304 installed on the top of the support 1. A second tank cover 310 is installed on the top of the transfer tank 301. An inlet pipe 309 is installed around the top of the second tank cover 310. One end of the inlet pipe 309 is connected to the delivery hose 4, and the other end of the inlet pipe 309 extends into the inner cavity of the transfer tank 301.

[0033] Furthermore, a vacuum head 308 is installed at the center of the second can lid 310, and the air inlet end of the vacuum pump 304 is connected to a vacuum tube 307, with the air inlet end of the vacuum tube 307 connected to the top of the vacuum head 308.

[0035] Furthermore, a cylinder 6 is installed on the bracket 1, and the telescopic end of the cylinder 6 is connected to the lifting plate 212 of the settling mechanism 2.

[0036] When the diamond micro powder slurry is settled and classified, the diamond micro powder slurry is injected into the interior of the settling mechanism 2, and then settled inside the settling mechanism 2. During the settling process, the diamond micro powder falls to the bottom of the inner cavity of the settling mechanism 2.

[0037] The turbidity sensor 202 on the settling mechanism 2 detects the turbidity of the diamond micron powder slurry inside the settling tank 201. When the set concentration is reached, the cylinder 6 slowly moves the lifting plate 212 downward. The lifting plate 212 drives the drive device 206, the extraction pipe 205, and the stirring structure into the settling tank 201, moving the bent pipe 209 to the detection area of ​​the turbidity sensor 202. The sealing cover 204 seals the top of the settling tank 201. The extraction mechanism 3 extracts the qualified diamond micron powder slurry inside the settling mechanism 2 through the conveying hose 4 to remove the required slurry. During the extraction of diamond micron powder slurry of a certain concentration, the liquid level is monitored. When the set liquid level is reached, extraction is stopped. Water is then added to the settling mechanism 2, and the diamond micron powder slurry inside the settling mechanism 2 is stirred. After stirring, the cylinder 6 drives the lifting plate 212 to rise to the initial position, and then the settling and extraction continue to circulate and extract diamond micron powder slurry of a qualified concentration, thereby improving the efficiency of diamond micron powder slurry classification. The qualified diamond micron powder slurry inside the extraction mechanism 3 is discharged into the subsequent processing equipment to meet different process requirements.

[0038] During the operation of the settling mechanism 2, diamond micron powder slurry is poured into the settling tank 201. Then, the drive device 206 is started. The drive device 206 stirs the diamond micron powder slurry through the stirring rod 208, stirring blade 211, and stirring head 210. After the mixture is stirred evenly, the operation stops. Then, the cylinder 6 drives the lifting plate 212 to move upward, which in turn moves the stirring mechanism to the top of the inner cavity of the settling tank 201 to settle the diamond micron powder slurry. During the settling process, the turbidity sensor 202 monitors the settling tank. The turbidity of the diamond micron powder slurry in the inner cavity of 201 is detected. When the set value is reached, the pumping mechanism 3 and the conveying hose 4 extract the diamond micron powder slurry. During the extraction process, the radar liquid level sensor 207 detects the liquid level. When the set liquid level is reached, the extraction stops, and water is added to the settling tank 201 through the water inlet valve 203. When the water level reaches the set maximum level, the water addition stops. Then, the diamond micron powder slurry in the settling tank 201 is stirred and settled to facilitate the next extraction.

[0039] During the operation of the material extraction mechanism 3, the vacuum pump 304 evacuates the interior of the transfer tank 301 through the vacuum pipe 307 and the vacuum head 308, creating a negative pressure inside. After the negative pressure is generated, the transfer tank 301 extracts the diamond micron powder slurry from the settling tank 201 through the liquid inlet pipe 309, the conveying hose 4, the liquid extraction pipe 205, and the bend pipe 209. The bend pipe 209 is set upward to avoid extracting the diamond micron powder slurry that is too concentrated at the bottom. After entering the transfer tank 301, the diamond micron powder slurry is stored. The diamond micron powder slurry inside the transfer tank 301 is guided into the discharge pipe 305 through the funnel 302 and the connector 303, and finally discharged through the solenoid valve 306. The solenoid valve 306 automatically discharges the diamond micron powder slurry, thereby avoiding accumulation and blockage.
