Description

Technical Field

[0001] The present invention belongs to the technical field of battery material production, and specifically relates to a battery material iron removal device, and more particularly to a semi-automatic battery material slurry iron removal device which is convenient for quick disassembly, assembly and cleaning. Background Art

[0002] The battery material industry is an important part of the new energy field. With the rapid development of electric vehicles, energy storage systems and other markets, the demand for battery materials is growing. The quality of battery materials directly affects the performance and life of the battery. Therefore, it is crucial to ensure the high purity of battery materials. Iron removal is a key link in improving the purity of battery materials and is of great significance to the production of battery materials.

[0003] In the battery material industry, such as lithium battery materials, the requirements for the content of iron impurities are extremely strict, requiring iron impurities to be at the ppm level (parts per million). Iron impurities not only reduce the discharge capacity and cycle life of the battery, but may also cause short circuits and safety hazards inside the battery. Therefore, in the production process of battery materials, the content of iron impurities must be strictly controlled to ensure the performance and quality of the battery.

[0004] The iron removal method of battery materials is generally achieved by using the principle of magnetic adsorption. The corresponding equipment is a battery material iron removal device. The magnet can be a permanent magnet or an electromagnet. The magnet is placed in the battery material, and the iron filings impurities in the battery material are adsorbed on the magnet to achieve the purpose of iron removal. In order to improve the iron removal efficiency, in the battery material iron removal device, the liquid battery material slurry is generally continuously fed into the iron removal cylinder, and a magnet rod is set in the iron removal cylinder, and the iron filings are adsorbed on the magnet rod.

[0005] Battery material iron removal devices can be divided into fully automatic battery material iron removal devices and semi-automatic battery material iron removal devices according to the degree of automation, and can be divided into battery material slurry iron removal devices and battery material powder iron removal devices according to the form of battery materials; the basic structure of a traditional semi-automatic battery material slurry iron removal device includes a frame, an iron removal cylinder, a permanent magnet bar and a driving mechanism, a plurality of iron removal cylinders are installed on the frame, a plurality of permanent magnet bars are driven vertically by the driving mechanism, a plurality of permanent magnet bars are arranged above each iron removal cylinder and the upper ends of the plurality of permanent magnet bars are all installed on a permanent magnet bar mounting plate; when working, the permanent magnet bar is driven by the driving mechanism to move downward into the iron removal cylinder and is sealed with the cylinder flange at the upper end of the iron removal cylinder through the permanent magnet bar mounting plate, and then the battery material slurry is sent into the iron removal cylinder, and when the battery material slurry flows in the iron removal cylinder, the iron filings therein are adsorbed by the plurality of permanent magnet bars to achieve the purpose of iron removal.

[0006] The above-mentioned traditional semi-automatic battery material slurry iron removal device has the following defects: the permanent magnet rod mounting plate and the cylinder flange at the upper end of the iron removal cylinder are all connected by bolt locking. In the process of cleaning the iron removal cylinder and removing iron filings on the permanent magnet rod, the permanent magnet rod mounting plate and the cylinder flange need to be disassembled and assembled. Since the entire iron removal device generally includes multiple iron removal cylinders, each disassembly and assembly operation and multiple disassembly and assembly operations during batch production are time-consuming and labor-intensive, which reduces production efficiency and increases production costs.

[0007] In addition, the above-mentioned traditional semi-automatic battery material slurry iron removal device also has the following defects: the way to remove iron filings on the permanent magnet rod is to use hands or tools such as rags to remove the iron filings from the permanent magnet rod from top to bottom and make them fall into the storage container below. This method is not only time-consuming and labor-intensive, inefficient, and incomplete in removal, but also difficult to completely remove the iron filings stuck to the bottom of the permanent magnet rod mounting plate; and the lower end of the traditional permanent magnet rod is also cylindrical, and the iron filings are easy to adhere to the lower end face of the permanent magnet rod, and are not easy to completely remove; the above-mentioned traditional semi-automatic battery material slurry iron removal device has a sealing ring groove on the cylinder flange and an O-ring for sealing with the permanent magnet rod mounting plate is installed in the sealing ring groove. There is a gap between the lower part of the O-ring and the sealing ring groove and the battery material slurry is easy to gather in the gap, which makes it difficult to clean the iron removal cylinder, reducing the cleaning efficiency and production efficiency; the driving mechanism of the above-mentioned traditional semi-automatic battery material slurry iron removal device adopts a hydraulic cylinder, which is not only costly, but also not conducive to energy saving and environmental protection.

[0028] In order to prevent the battery material slurry in the iron removal cylinder 3 from adhering to the permanent magnet rod mounting plate 5, the hole diameter of the upper end of the hole wall of the central through hole of the cylinder flange 13 is enlarged to form an annular step 12 and the circumferential edge of the corresponding permanent magnet rod scraper 9 can be placed on the annular step 12.

[0029] In order to prevent the battery material slurry from accumulating in the sealing ring groove of the cylinder flange 13 and making it difficult to clean, so as to improve the cleaning efficiency and production efficiency, a circular sealing ring groove is provided on the top of the cylinder flange 13 near its central through hole, and an annular sealing ring 11 is installed in the sealing ring groove. The upper part of the radial cross-section of the annular sealing ring 11 is circular, the lower part is square, and the lower outer wall is in close contact with the bottom and the groove walls on both sides of the sealing ring groove.

[0030] In order to reduce the driving cost and facilitate energy saving and environmental protection, the driving mechanism is a cylinder 18 , and the upper ends of the push rods 16 of the two cylinders 18 are connected to the two ends of the driving bracket 4 through floating joints 15 respectively.

[0031] Figure 1 and Figure 2 Also shown are the feed connector 2, the discharge connector 14 and the sampling connector 8 connected to the corresponding iron removal cylinder 3, and the guide rod 17 connected between the drive 4 and the cylinder 18. These structures are all conventional adaptive structures.

[0032] like Figure 1-Figure 6As shown, when removing iron, the cylinder 18 is used to drive the driving bracket 4 to move downward, and the driving bracket 4 drives multiple permanent magnet bar mounting plates 5, multiple permanent magnet bars 6, and multiple permanent magnet bar scrapers 9 to move downward synchronously until multiple permanent magnet bars 6 are respectively located in the corresponding iron removal cylinder 3, the edges of multiple permanent magnet bar scrapers 9 are respectively placed on the corresponding annular steps 12, and multiple permanent magnet bar mounting plates 5 are respectively located on multiple cylinder flanges 13 and basically press the corresponding annular sealing rings 11, and the control cylinder 18 stops running. At this time, the upper surface of the permanent magnet bar scraper 9 is in contact with the corresponding The cam 76 is in the state of being in contact with the bottom of the permanent magnet bar mounting plate 5; each locking device 7 is then operated as follows: the long handle bar of the "L" shaped locking handle 71 is held and moved upward, and the "L" shaped locking handle 71 and the locking connecting rod will rotate around the first locking pin 76 until the middle section of the locking connecting rod passes through the corresponding first "U" shaped groove on the cylinder flange 13 and the permanent magnet bar mounting plate 5 and is in a vertical position; then the long handle bar of the "L" shaped locking handle 71 is held and moved downward to rotate it around the second locking pin 74, and the short handle bar of the "L" shaped locking handle 71 is used to lock the cam 76. The suspended end of the permanent magnet rod 9 presses the hard gasket 75, the hard gasket 75 presses the permanent magnet rod mounting plate 5, the permanent magnet rod mounting plate 5 presses the corresponding annular sealing ring 11, the upper surface of the permanent magnet rod scraper 9 is in close contact with the lower surface of the corresponding permanent magnet rod mounting plate 5, and the locking operation of the locking device 7 is completed; when all the locking devices 7 have completed the locking operation, all the permanent magnet rod mounting plates 5 are sealed and connected with the corresponding cylinder flanges 13, and then the relevant valves are opened to feed the battery material slurry from the feed joint 2 into the first iron removal cylinder 3, and then After passing through the multiple iron removal cylinders 3 at the back, the multiple permanent magnet rods 6 in each iron removal cylinder 3 will strongly adsorb the iron filings in the battery material slurry until they are basically completely adsorbed, and the battery material slurry after iron removal is sent out from the discharge connector 14 to the storage tank or the next process; during the iron removal process, the iron content in the battery material slurry is sampled and detected through the sampling connector 8, and the iron removal effect of the battery material slurry at the corresponding flow rate is understood based on the iron content, and the flow rate is adjusted based on this to achieve better iron removal effect and maintain high production efficiency.

[0033] After a period of iron removal, a lot of iron filings will be adsorbed on the permanent magnet bar 6. In order to prevent the iron filings from falling and reducing the iron removal effect, the permanent magnet bar 6 needs to be iron-removed. At this time, the locking device 7 needs to be reversed to quickly disassemble the permanent magnet bar mounting plate 5 and the corresponding cylinder flange 13, and the cylinder 18 drives multiple permanent magnet bar mounting plates 5, multiple permanent magnet bars 6 and multiple permanent magnet bar scrapers 9 to move upward to the original position, and a container for accommodating iron filings is placed (or held by hand) under the permanent magnet bar 6, and then the permanent magnet bar scraper 9 is held and moved from top to bottom until the permanent magnet bar scraper 9 is separated from the corresponding permanent magnet bar 6, so that most of the iron filings can be scraped into the container, and then the iron filings on the cone 61 at the lower end of the permanent magnet bar 6 can be scraped off by hand or a rag or other tool, that is, the iron removal operation of the permanent magnet bar 6 is completed. The whole process is much simpler and faster than the traditional hand-scraping of the permanent magnet bar 6, and the removal is more thorough; then the locking process of the locking device is operated according to the above-mentioned locking process, and the iron removal operation of the battery material slurry can be continued. If the iron removal cylinder 3 needs to be cleaned, the disassembly and assembly process is the same as above, and the disassembly and assembly efficiency is significantly improved compared with the traditional bolt connection structure.

[0034] The above embodiments are only preferred embodiments of the present invention and are not limitations of the technical solutions of the present invention. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present invention.
