Description

[0002] Cobalt-nickel salts refer to inorganic salt compounds containing cobalt (Co) and nickel (Ni) elements. These salts are usually oxides, chlorides, sulfates, nitrates or salts of other acids of cobalt and nickel. Cobalt-nickel salts are widely used in the chemical industry, battery manufacturing, metal smelting and other fields. The high-efficiency extraction and separation device of cobalt-nickel salts uses physical and chemical methods to efficiently and purely separate and extract cobalt and nickel elements from raw materials.

[0003] The existing high-efficiency extraction and separation device for cobalt-nickel salts is in use. The organic solvent and the leaching solution are added into the extraction tank and fully mixed to form a stable complex with the target ions (cobalt and nickel) in the leaching solution. Then the extractant is added and fully stirred with it to achieve separation of the target metals. The target metals are extracted by standing and stratifying.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

A transmission rod 13 is fixedly connected, stirring blades 14 are fixedly connected to the outside of the transmission rod 13, and scraping components 15 are arranged around the outside of the transmission rod 13. The scraping components 15 are used to scrape the liquid attached to the inner wall of the extraction tank 2. The scraping components 15 include a mounting rod 1501, and the mounting rod 1501 is fixedly connected to the outside of the transmission rod 13. Scrapers 1502 are fixedly connected to the outside of multiple connecting rods 10, and multiple scrapers 1502 are fitted with the inner wall of the extraction tank 2. The rear side of the outside of the cross plate 3 is fixedly connected to the mounting ring 4, and the motor 5 is fixedly connected to the inside of the mounting ring 4. The first feed port 27 is fixedly connected to the left side of the outside of the extraction tank 2, and the second feed port 28 is fixedly connected to the right side of the outside of the extraction tank 2.

[0027] When extracting and separating cobalt-nickel salt, first, cobalt-nickel salt raw material and leachate are added to the inside of the extraction tank 2 through the first feed port 27 and the second feed port 28. The cobalt-nickel salt raw material is a solid material after pretreatment, and the leachate is a chemical solution with a specific ratio, which can effectively dissolve and separate cobalt and nickel compounds. Then, the motor 12 is started, and the motor 12 drives the transmission rod 13 fixed at its output end to rotate, and the rotation of the transmission rod 13 drives the stirring blades 14 fixed around its outside to rotate. Through the rotation of the stirring blades 14, the cobalt-nickel salt raw material and the leachate inside the extraction tank 2 are fully mixed, so that the material and the solvent can be evenly contacted, thereby improving the extraction efficiency. At the same time, the motor 5 is started, and the motor 5 drives the turntable 6 fixed at its output end to rotate, and the rotation of the turntable 6 drives the fixed rod 7 fixed outside to rotate. The rotation of the fixed rod 7 drives the reciprocating rod 8 sleeved on the outside to reciprocate inside the two guide rings 9. When the reciprocating rod 8 moves, the connecting rod 10 fixed at the bottom thereof moves together, and the movement of the connecting rod 10 drives the installation shell 11 fixed at the bottom thereof to move. The movement of the installation shell 11 causes the motor 12 fixed inside to move accordingly, and the movement of the motor 12 drives the transmission rod 13 fixed at its output end to rotate. The rotation of the transmission rod 13 again drives the stirring blades 14 fixed around the outside thereof to move and rotate. Through the above design, it is achieved that during the extraction process, different upper and lower areas inside the extraction tank 2 can be stirred. This multi-level stirring method ensures the uniform distribution of materials in the extraction tank 2, which not only increases the contact area and contact time between the cobalt-nickel salt and the leachate, thereby accelerating the reaction rate between the cobalt-nickel and the leachate, but also improves the extraction efficiency, ensuring the high purity and high quality of the final product. When the transmission rod 13 rotates, the mounting rod 1501 fixed on the outside rotates. The mounting rod 1501 rotates and moves the scraper 1502 fixed on the outside on the inner wall of the extraction tank 2 to scrape off the liquid attached to the inner wall of the extraction tank 2, ensuring that all materials and leachate fully participate in the reaction to avoid waste.

[0029] When the filter plate 18 needs to be cleaned, first, move the handle 23. The handle 23 drives the externally fixed slider 22 to move inside the installation cavity 29. When the slider 22 moves, it drives the lower fixed plug rod 25 to move, and at the same time squeezes the upper fixed telescopic rod 30 to shrink the telescopic rod 30. At the same time, the externally sleeved spring 21 is deformed by force to generate compression force. Then, when the plug rod 25 is separated from the inside of the socket 26, the filter plate 18 can be easily taken out from the inside of the filter barrel 17 for cleaning.

The surface of the cleaned filter plate 18 is smooth and flawless, which helps to improve the filtering effect and efficiency.

The discharge port 20 is provided to facilitate the discharge of the extracted material.

[0030] Working principle: When extracting and separating cobalt-nickel salts, first, cobalt-nickel salt raw materials and leachate are added into the extraction tank 2 through the first feed port 27 and the second feed port 28, and then the motor 12 is started, and the motor 12 rotates with the transmission rod 13 fixed at the output end, and the transmission rod 13 rotates with the stirring blades 14 fixed on the outside to rotate, and the cobalt-nickel salt raw materials and leachate in the extraction tank 2 are mixed by the rotation of the stirring blades 14, and at the same time, the motor 5 is started, and the motor 5 rotates with the turntable 6 fixed at the output end, and the rotation of the turntable 6 rotates with the fixed rod 7 fixed on the outside, and the fixed rod 7 rotates with the reciprocating rod 8 sleeved on the outside to reciprocate inside the two guide rings 9, and when the reciprocating rod 8 moves, it moves with the connecting rod 10 fixed at the bottom, and the connecting rod 10 moves with the installation shell 11 fixed at the bottom, and the installation shell 11 moves with the motor 12 fixed inside, and the motor 12 moves with the transmission rod 13 fixed at the output end to rotate, and the transmission rod 13 rotates with the stirring blades 14 fixed on the outside to move, so that the extraction tank 2 is convenient to be extracted during the extraction process. The different upper and lower areas inside are stirred to ensure the uniform distribution of the materials in the extraction tank 2, which can accelerate the contact between cobalt and nickel and the leaching agent, increase the reaction rate and thus improve the extraction efficiency. Then, when the filter plate 18 needs to be cleaned, first, the handle 23 is moved, and the handle 23 moves inside the mounting cavity 29 with the externally fixed slider 22. When the slider 22 moves, it moves the lower fixed plug rod 25 and squeezes the upper fixed telescopic rod 30, so that the telescopic rod 30 contracts and the externally sleeved spring 2 1 is deformed by force, and then, when the insertion rod 25 is separated from the inside of the insertion hole 26, the filter plate 18 can be taken out from the inside of the filter barrel 17 for cleaning. When installing, the filter plate 18 is inserted into the inside of the filter barrel 17, and then, after loosening the grip 23, the insertion rod 25 is inserted into the inside of the insertion hole 26 under the reaction force of the spring 21. The extraction and separation device is realized, and the filter plate 18 is easy to disassemble and clean. The clean filter plate 18 can effectively remove impurities, ensure the accuracy and purity of the separation process, and thus improve the quality of the final product.
