Description

Technical Field

[0001] This utility model belongs to the field of rare earth polishing fluid extraction technology, and in particular relates to a rare earth polishing fluid extraction device. Background Technology

[0002] Rare earth polishing slurry is a polishing material with cerium oxide as the main component and mixed rare earth oxides. It has the characteristics of uniform particle size, moderate hardness, high polishing efficiency and environmental protection. It is mainly used for precision polishing of optical components, precision glass, semiconductors and high-end jewelry. It is especially suitable for curved glass, soft optical components and high-precision flat surface processing. Its polishing particles have strong stability, good suspension and are easy to clean.

[0003] Chinese patent application CN219032300U discloses a rare earth polishing liquid extraction device, including an extraction tank with a rotating shaft passing through its interior. A suction pipe is connected to the top of the extraction tank, and a receiving tank is installed on the outside. This device uses an observation window and scale to allow a guide rod to move up and down and adjust its position. The guide rod, via a guide plate, drives a telescopic tube to extend and retract, moving along a guide groove and guide hole to the liquid layer to be extracted and separated. A pump generates suction, causing the extracted liquid layer to enter the telescopic tube and suction pipe, and then into the receiving tank for extraction and separation. Inclined stirring blades are installed on the surface of the rotating shaft, which agitate the liquid in the extraction tank, preventing centrifugal stratification and ensuring thorough mixing.

[0004] Although the patented technology can control the telescopic tube to move to the liquid layer that needs to be extracted and separated by the guide rod, it requires the operator to visually judge the position of the layer interface and operate the height of the telescopic tube. This process relies on human experience and has problems such as delayed recovery timing, poor operation continuity and low degree of automation, resulting in reduced extraction efficiency. In addition, it is easy to cause cross-contamination of liquids of different densities due to human misjudgment, which is not conducive to use.

[0005] To address these issues, we provide a rare earth polishing fluid extraction device. Utility Model Content

By combining an automatic extraction slurry recovery component and a rapid mixing component, it solves the problems of existing rare earth polishing slurry extraction devices that lack an automatic extraction slurry recovery function, require manual control of the recovery tube to the stratification point of the extraction slurry and rare earth solution, and suffer from delayed recovery timing, poor operation continuity, and low automation.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a rare earth polishing liquid extraction device, comprising a tank, an automatic extraction liquid recovery component, and a rapid mixing component.

[0012] The present invention is further configured such that sliding grooves are provided on both sides of the limiting plate, and sliding strips are slidably connected to the inner cavity of the sliding grooves. The opposite sides of the two sliding strips are fixedly connected to the inner wall of the reset shell.

[0016] The present invention has the following beneficial effects.

[0017] 1. This utility model utilizes an automatic extract recovery component, employing a servo motor to drive a screw to rotate. This screw, in turn, precisely adjusts the height of the threaded sleeve, movable frame, and industrial camera until the industrial camera detects a clear boundary, at which point it automatically stops moving. During this process, the movable frame moves synchronously with the adjusting rod and telescopic tube, ensuring the collection hood is accurately positioned within the extract layer. This achieves automatic extract recovery, effectively eliminating errors caused by manual visual inspection and operational delays. It also improves operational continuity and automation levels, avoids the risk of cross-contamination between liquids of different densities, and enhances extraction efficiency and product purity.

[0018] 2. This utility model utilizes a rapid mixing component, where a drive motor rotates the rotating shaft. The rotating drum periodically contacts the protrusions at the bottom of the tank, forcing the reset shell to slide upwards along the rotating shaft and compress the spring. When the rotating drum disengages from the protrusions, the spring pushes the reset shell back to its original position, forming a reciprocating motion. The mixing paddle, through the combined action of rotation and lifting, strongly disturbs the rare earth solution and extractant, significantly shortening the mixing time, enhancing the mixing uniformity, accelerating the extraction reaction rate, and further improving overall production efficiency.

The drive motor 51 is started, and the drive motor 51 drives the rotating shaft 52 to rotate. The rotating shaft 52 cooperates with the slide rail through the limiting plate 532, driving the reset shell 531 to rotate. During the rotation, the rotating roller 535 at the bottom of the reset shell 531 repeatedly collides with the protrusion 55, pushing the reset shell 531 to move upward along the rotating shaft 52 and compressing the spring 533. When the rotating roller 535 passes the protrusion 55, the spring 533 releases its elastic force, causing the reset shell 531 to move downward rapidly. The mixing paddle 534 violently agitates the liquid under the action of rotation and lifting, achieving efficient mixing. The mixing process significantly shortens the mixing time and enhances the mixing uniformity. After mixing is completed, the drive motor 51 is turned off, and the liquid settles and separates in the tank 1. Then, the servo motor 412 starts and drives the screw 413 to rotate. The threaded sleeve 414 drives the movable frame 42 to move down. The industrial camera 43 on the movable frame 42 captures the layered image in real time through the viewing window 2. When the interface position is identified, the servo motor 412 stops. At the same time, the movable frame 42 uses the adjusting rod 44 to position the collection cover 46 at the end of the telescopic tube 45 to the extraction liquid layer. The pump draws the extraction liquid and discharges it to the external container through the telescopic tube 45. The remaining rare earth solution is discharged from the tank 1 through the discharge pipe, completing the extraction process.
