Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-6 The system includes an extractor 1, with a heavy phase inlet 2 installed at the bottom and a light phase inlet 3 installed on the upper side of the heavy phase inlet 2. The extractor 1 is evenly fixed on a support frame 4, and a drive motor 5 is installed on the top of the extractor 1. Heavy phase outlets and light phase outlets are provided at corresponding positions on the back sides of the heavy phase inlet 2 and the light phase inlet 3. A positioning component is provided inside the extractor 1, which is located at the bottom end of the drive motor 5 and is installed on a receiving component. A drum assembly is installed inside the extractor 1, a replacement component is installed inside the extractor 1, and a collection component is installed at the bottom of the extractor 1.

[0022] The positioning rods 501 in the positioning assembly are evenly and fixedly installed on the bottom of the snap-fit ​​protrusion ring 502. The snap-fit ​​protrusion ring 502 is installed on the outer side of the bottom end of the mounting protrusion plate 503. The mounting protrusion plate 503 is fixedly installed at the bottom end of the drive motor 5. The positioning rods 501 are adapted to slide and snap into the inside of the snap-fit ​​groove 504. The snap-fit ​​groove 504 is evenly arranged in the positioning groove 505.

[0023] The bottom of the mounting protrusion 503 in the positioning assembly is fitted with a sealing gasket 506, and the snap-fit ​​protrusion 502 is matched and snapped into the snap-fit ​​groove 504. The mounting protrusion 503 is fixedly installed on the snap-fit ​​groove 504 by a positioning pin. The snap-fit ​​groove 504 is located on the top of the receiving cylinder 601.

[0024] In use, the extraction machine 1 is fixed on the horizontal working surface by the support frame 4 to ensure the overall stability of the device. The positioning component enables the precise docking of the drive motor 5 and the receiving component. The snap-fit ​​ring 502 at the bottom of the mounting plate 503 is aligned with the snap-fit ​​groove 504 at the top of the receiving cylinder 601. The positioning rod 501 slides into the positioning groove 505 to complete the pre-positioning. The mounting plate 503 is then fixed with the positioning pin. The sealing gasket 506 seals the connection to prevent leakage. After the drive motor 5 is started and preheated, the heavy phase liquid is continuously fed into the heavy phase inlet 2, and the light phase extractant is simultaneously fed into the light phase inlet 3. The two materials are initially mixed in the extractor 1. The drive motor 5 drives the subsequent drum assembly to rotate, and the light and heavy phases are rapidly separated by centrifugal force. The heavy phase flows downward along the inner wall of the extractor 1 and is finally discharged from the heavy phase outlet on the back side. The light phase gathers in the middle and flows upward and is discharged from the light phase outlet on the back side. The mixing and stratification of the internal materials can be observed in real time through the observation window 602 of the receiving cylinder 601 to ensure a stable match between the feeding and discharging rates.

[0025] Example 2: Based on Example 1, please refer to... Figures 2-5 An observation window 602 is fixedly provided in the middle of the receiving cylinder 601 in the receiving assembly, and the second mounting protrusion 603 at the bottom of the receiving cylinder 601 is fixedly installed on the support frame 4 and the extraction machine 1 by a positioning pin.

[0026] The mounting head 702 at the top of the rotating shaft 701 in the drum assembly is firmly mounted on the bottom of the drive motor 5. A first baffle 703 is sleeved and installed in the middle of the rotating shaft 701. The inner diameter of the first baffle 703 is much smaller than the inner diameter of the filter cartridge 704.

[0027] The bottom of the filter cylinder 704 in the drum assembly is provided with an installation ring 705. A connecting rod 706 is fixedly installed on the installation ring 705. The other end of the connecting rod 706 is fixedly installed on the rotating shaft 701. Filter strips 707 are evenly arranged on the upper side of the filter cylinder 704. A filter bucket 708 is fixedly sleeved on the bottom end of the rotating shaft 701.

[0028] The filter hopper 708 in the drum assembly is evenly provided with filter holes 709. The filter holes 709 are installed with an inner diameter that gradually increases from bottom to top. A folded stirring rod 714 is evenly installed at the bottom end of the filter hopper 708. The bottom end of the folded stirring rod 714 is fixedly installed on the upper side of the fixing ring 710. The fixing ring 710 is firmly installed on the rotating shaft 701 by the rod. A fixing ring 711 is fixedly sleeved at the bottom of the rotating shaft 701. A fixed protrusion 712 is fixedly installed on the fixing ring 711. A scraper 713 is fixedly installed on the fixed protrusion 712. The scraper 713 is in close contact with the bottom inner wall of the extractor 1.

[0029] In use, based on the installation and fixation in Example 1, the drive motor 5 drives the rotating shaft 701 to rotate at high speed through the mounting head 702, starting the centrifugal extraction process. The heavy phase feed liquid and the light phase extractant enter the extractor 1 through the heavy phase inlet 2 and the light phase inlet 3, respectively. The first baffle 703 prevents the material from directly impacting the filter cylinder 704, allowing the material to enter the drum area smoothly. The rotating shaft 701 drives the filter cylinder 704 and the filter hopper 708 to rotate synchronously at high speed. The centrifugal force generated causes the light phase to penetrate the filter strip 707 and the filter hole 709 and separate outwards. The inner diameter of the filter hole 709 gradually increases from bottom to top. The design expands to avoid clogging while improving separation efficiency. The heavy phase moves downward along the inner wall of the filter cylinder 704 under centrifugal force. During rotation, the folded stirring rod 714 stirs the material, enhancing the mass transfer between the two phases. The scraper 713 on the fixing ring 711 rotates close to the bottom inner wall of the extractor 1 to scrape off the deposited heavy phase impurities, preventing the accumulation of material at the bottom from affecting the separation effect. The stratified light phase is discharged from the back light phase outlet, and the heavy phase is discharged through the subsequent collection component. The working status of the filter bar 707 and the filter hopper 708 is monitored through the observation window 602 to ensure the stability of the separation process.

[0030] Example 3: Based on Example 2, please refer to... Figures 4-6 The replacement shaft 801 in the replacement assembly is installed at the bottom end of the drive motor 5. A sturdy sleeve 802 is uniformly fixedly sleeved on the replacement shaft 801. A second sturdy protrusion 803 is fixedly provided on the sturdy sleeve 802. A second scraper 804 is fixedly installed at the end of the second sturdy protrusion 803.

[0031] The replacement shaft 801 and the bottom end of the replacement shaft 701 in the replacement assembly are both provided with a fixing hammer 805. The fixing hammer 805 is installed inside the collection port 901 at the bottom end of the extractor 1. The outer diameter of the fixing hammer 805 is smaller than the inner diameter of the collection port 901. The length of the second sturdy protrusion 803 decreases from top to bottom. The second scraper 804 is in close contact with the inner wall of the extractor 1. The replacement shaft 801 replaces the original shaft 701 by stopping the machine. The replacement shaft 801 is driven to rotate by the drive motor 5, which drives the second scraper 804 to scrape the inside of the extractor 1.

[0032] The collection port 901 in the collection assembly is fixedly installed at the bottom end of the extractor 1. The collection port 901 is evenly provided with threads. The outer side of the collection port 901 is threadedly connected to a tightening end 902. The tightening end 902 is fixedly installed at the bottom end of the extractor 1 by a fixing pin. A central rod 903 is fixedly installed inside the tightening end 902. A top plate 904 is fixedly installed on the top of the central rod 903. Outflow holes 905 are provided on both sides of the top plate 904.

[0033] In use, based on the centrifugal extraction in Example 2, when material residue appears on the inner wall of the extractor 1 or the drum assembly needs maintenance, the positioning pin is removed after stopping the machine, the original rotating shaft 701 is taken off, and the replacement rotating shaft 801 is installed at the bottom end of the drive motor 5 through the mounting head 702. Its bottom fixing hammer 805 is embedded in the collection port 901. The drive motor 5 is started, and the replacement rotating shaft 801 drives the second fixed protrusion 803 on the fixed sleeve 802 to rotate. Because the length of the second fixed protrusion 803 decreases from top to bottom, the second scraper 804 can fully and tightly adhere to the inner wall of the extractor 1 to scrape off residual sediment at different heights. The sediment falls to the collection port under the action of centrifugal force and gravity. During normal operation of the purification process, the collection component is fixed to the collection port 901 by the screw-on end 902. The outflow holes 905 on both sides of the top plate 904 allow the heavy phase material to be discharged smoothly. The central rod 903 ensures the stability of the top plate 904. During the centrifugal separation process, the light phase is separated by the filter strip 707 and filter holes 709 and discharged from the light phase outlet on the back side. The heavy phase is collected by the filter bucket 708 and flows downward along the inner wall of the extractor 1. It is discharged through the collection port 901 and the outflow holes 905. The fixing hammer 805 can prevent the collection port 901 from being blocked and ensure the orderly collection of the purified product. After maintenance, the original rotating shaft 701 can be replaced to restore normal centrifugal extraction operation. Although the illustrative specific embodiments of this application have been described above to enable those skilled in the art to understand this application, this application is not limited to the scope of the specific embodiments. For those skilled in the art, all applications utilizing the concept of this application are protected as long as various variations are within the spirit and scope of this application as defined and determined by the appended claims.
