Description

Technical Field

[0001] The utility model relates to the field of extraction technology, and specifically relates to an extraction device for low-concentration rare earth oxides. Background Art

[0002] Extraction is a method of transferring a substance from one solvent to another by taking advantage of the difference in solubility or distribution coefficient of the substance in two immiscible (or slightly soluble) solvents. This process is usually used to separate mixtures and is a physical process widely applied in multiple fields such as chemistry, metallurgy, food, and medicine. Rare earth oxide extraction is one of the key technologies for the purification and separation of rare earth elements, and mainly realizes the separation and purification of rare earth elements through methods such as solvent extraction.

[0003] An extraction device for producing rare earth oxides proposed according to the publication number: CN220424596U includes an extraction tank and three support legs fixedly installed at the bottom of the extraction tank. Buffer mechanisms are provided on all three support legs. The buffer mechanism includes a pressing block and hydraulic oil. A tank cover is provided on the extraction tank. A feed port is opened on the upper side wall surface of the tank cover. A connecting rotating rod is rotatably installed on the wall surface of the tank cover. A rotating mechanism is provided on the connecting rotating rod. A stirring paddle is fixedly installed on the outer wall of the connecting rotating rod in a detachable manner. During the use of this utility model, materials are injected into the interior of the extraction tank through the feed port. Then, the water source between the water tank and the rotating pipe is connected. At the same time, the connecting rotating rod is rotated through the rotating mechanism, and the stirring paddle stirs the products inside to facilitate the extraction operation. The water liquid is injected into the interior of the water spraying disc through the rotating pipe, and finally sprayed out through the spray heads to wash the wall surface of the extraction tank.

Therefore, when washing the inner wall of the extraction device, only the positions sprayed by the spray heads can be washed, and the inner wall of the extraction device at the lower end of the spray heads will still have residues of the extract, resulting in the inner wall of the rare earth oxide extraction device not being cleaned thoroughly, thus reducing the washing and cleaning effect of the rare earth oxide extraction device. To solve the above-mentioned problems, an extraction device for low-concentration rare earth oxides is proposed. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] The present invention provides a low-concentration rare earth oxide extraction device as Figures 1 to 5 shown, which includes a reaction tank 1. A stirring mechanism 2 is installed on the reaction tank 1. The bottom of the stirring mechanism 2 is rotatably connected to the bottom of the inner cavity of the reaction tank 1. A cleaning mechanism 3 that cooperates with the stirring mechanism 2 is provided on the inner wall of the reaction tank 1. A spraying assembly 4 is provided on the outer wall of the reaction tank 1. One end of the spraying assembly 4 penetrates into the inner cavity of the reaction tank 1. By providing the stirring mechanism 2, the low-concentration rare earth oxide and the reactant can be fully mixed and reacted, so that the extraction effect of the low-concentration rare earth oxide is faster and better. At the same time, a cleaning mechanism 3 is provided at the position of the stirring mechanism 2. Therefore, when the stirring mechanism 2 rotates, it can drive the cleaning mechanism 3 to rotate. Thus, the inner wall of the reaction tank 1 can be scraped to remove the residual extract on the surface. Subsequently, the spraying assembly 4 provides a flushing effect on the inside of the reaction tank 1, thereby enhancing the cleaning effect on the inside of the low-concentration rare earth oxide extraction device, making the inner wall of the low-concentration rare earth oxide extraction device cleaner and reducing the residues on the inner wall.

[0024] Feeding pipes 5 are symmetrically embedded at the top of the reaction tank 1. The lower ends of the feeding pipes 5 are located between the stirring mechanism 2 and the cleaning mechanism 3 and extend downward. Discharge pipes 6 are communicated at symmetrically located positions at the bottom of the reaction tank 1. A control valve 7 is installed on the surface of the discharge pipe 6. By providing the feeding pipes 5, it is convenient to introduce the reactant and the low-concentration rare earth oxide into the reaction tank 1. By providing the discharge pipes 6, the extracted low-concentration rare earth oxide can be discharged, and the discharge speed of the discharge pipe 6 can be controlled by the control valve 7.

[0025] The stirring mechanism 2 includes a stepper motor 21, which is installed at the center of the top of the reaction tank 1. The output shaft of the stepper motor 21 is connected to a driving rod 22. A transmission assembly 23 is fixedly connected to the surface of the upper end of the driving rod 22. A driven rod 24 is fixedly connected to the inner cavity of the transmission assembly 23. The top of the driven rod 24 is rotatably connected to the top of the reaction tank 1 through a bearing. The bottom ends of the driven rod 24 and the driving rod 22 are rotatably connected to the bottom of the inner cavity of the reaction tank 1 through bearings. Stirring blades 25 are fixedly connected to the surfaces of the driven rod 24 and the driving rod 22 in sequence from top to bottom. By setting the stepper motor 21 to provide driving force, the driving rod 22 is driven to rotate. Subsequently, the driving rod 22 drives the driven rod 24 and the cleaning mechanism 3 to rotate through the cooperation of the transmission assembly 23. Finally, the driven rod 24 and the driving rod 22 drive the stirring blades 25 to quickly mix the low-concentration rare earth oxide and the reactant, accelerating the extraction rate of the low-concentration rare earth oxide.

[0026] The transmission assembly 23 includes a driving gear 231. Driven gears 232 are meshed at symmetrical positions on the surface of the driving gear 231. The inner cavity of the driven gear 232 is fixedly connected to the surface of the driven rod 24. The inner cavity of the driving gear 231 is fixedly connected to the surface of the driving rod 22.

One side of the scraping plate 35 is attached to the inner wall of the reaction tank 1. By setting the cooperation of the fixing ring 31 and the limiting groove 32, a supporting, limiting and sliding function can be provided for the gear ring 33, enabling the gear ring 33 to rotate in the limiting groove 32 of the fixing ring 31 driven by the driven gear 232. Thus, the scraping plate 35 is driven by the connecting rod 34 to rotate on the inner wall of the reaction tank 1, thereby cleaning the extract adhered to the inner wall of the reaction tank 1 and enhancing the cleaning cleanliness of the reaction tank 1.

[0028] A limiting ring 8 is fixedly connected to the bottom of the scraping plate 35, and the limiting ring 8 is attached to the inner wall of the reaction tank 1. By setting the cooperation of the limiting ring 8, the stability between the scraping plates 35 is enhanced, so that the scraping plates 35 can be more tightly attached to the inside of the reaction tank 1.

[0029] The spraying assembly 4 includes a ring pipe 41 sleeved on the outer wall of the reaction tank 1. Four sides inside the ring pipe 41 are communicated with spraying pipes 42.

The water flow is conveyed into the ring pipe 41 through the arranged conveying pipe 43, and then the water flow is sprayed into the inside of the reaction tank 1 through the spraying pipes 42 and cooperates with the scraping plate 35, so that the scraping plate 35 sprays the inner wall of the reaction tank 1 through the spraying pipes 42 during the scraping process, enhancing the cleaning effect of the low-concentration rare earth oxide extraction device.

[0030] During specific use, first, the reactant and low-concentration rare earth oxide are introduced into the reaction tank 1 through the feed pipe 5. Subsequently, the driving force is provided by setting the stepping motor 21 to drive the driving rod 22 to rotate. Then, the driving rod 22 drives the driven rod 24 and the cleaning mechanism 3 to rotate through the cooperation of the transmission assembly 23. Finally, the driven rod 24 and the driving rod 22 drive the stirring blades 25 to quickly mix the low-concentration rare earth oxide and the reactant, accelerating the extraction speed of the low-concentration rare earth oxide. Then, the driven gear 232 meshes with the gear ring 33, and through the cooperation of the arranged fixed ring 31 and the limiting groove 32, the gear ring 33 can be supported, limited, and slid, enabling the gear ring 33 to rotate in the limiting groove 32 of the fixed ring 31 driven by the driven gear 232. Thus, the scraping plate 35 is driven to rotate on the inner wall of the reaction tank 1 through the connecting rod 34, so as to clean the extract adhered to the inner wall of the reaction tank 1. Meanwhile, the water flow is conveyed into the ring pipe 41 through the arranged conveying pipe 43, and then the water flow is sprayed into the inside of the reaction tank 1 through the spraying pipes 42 and cooperates with the scraping plate 35, so that the scraping plate 35 sprays the inner wall of the reaction tank 1 through the spraying pipes 42 during the scraping process, enhancing the cleaning effect of the low-concentration rare earth oxide extraction device and enhancing the cleanliness of the cleaning of the reaction tank 1.
