Description

Technical Field

[0001] The utility model relates to the technical field of iron removal, in particular to an electromagnetic iron remover. Background Art

[0002] The raw materials for producing positive electrode materials for lithium batteries are powders. The raw materials need to be sintered, poured out of the furnace, and then crushed to form powders. Magnetic foreign matter needs to be removed during the production process to ensure product performance. The powder can be removed by contacting and adsorbing the inside of a rotating iron remover or a permanent magnetic iron remover with a magnetic surface. The stainless steel body of the sintering kiln will be corroded and dropped by the high-temperature and highly corrosive kiln exhaust during long-term operation, which will cause certain losses to the production equipment. Therefore, it is necessary to remove iron from the semi-finished products before the pouring and crushing process. The raw materials are in the burning bowl after sintering, and the hardness of the semi-finished products is relatively high at this time, so they cannot be removed by the existing iron removal device.

[0003] Currently, after the raw materials are sintered out of the furnace, they are manually adsorbed and iron removed from their surfaces using handheld permanent magnets, which not only increases labor costs but also poses a risk of leakage.

[0004] In addition, to ensure the adsorption effect, the permanent magnet rod needs to be close to the surface of the semi-finished product, and the hardness of the raw material after sintering is relatively high. During this process, the handheld permanent magnet rod is prone to collision and contact with the semi-finished product, causing damage. The foreign matter produced by the damage flows into the semi-finished product, adding new impurities and affecting the quality of the product. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an electromagnetic iron remover which can avoid collision and wear, has a simple structure and is easy to disassemble.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] An electromagnetic iron remover is arranged at a workstation between a sintering furnace and a material pouring device, comprising a frame, a driving member mounted on the frame, and an electromagnet fixedly connected to the driving member, wherein the electromagnet is flexibly connected to the driving member through a connecting member.

[0008] As a further improvement of the above technical solution:

[0009] The driving member is configured as a double-shaft cylinder, and a balance plate is fixedly connected to the end of the piston rod of the double-shaft cylinder.

[0010] The connecting member comprises a plurality of chains, one end of each chain is connected to the electromagnet, and the other end is fixedly connected to the balance plate.

[0011] The connecting member also includes a plurality of adjusting bolts and nuts. Each of the adjusting bolts is passed through the balance plate and is locked and fixed by a nut. The chain is fixed to the end of the adjusting bolt.

[0012] The balancing plate is provided with a threaded hole matching the adjusting bolt.

[0013] The electromagnet is provided with a lifting ring fixedly connected to the chain, and the lifting ring is threadedly connected to the electromagnet.

[0014] The outer surface of the electromagnet is sprayed with a coating, and the coating is set as a Teflon coating.

[0015] Compared with the prior art, the advantages of the utility model are:

[0016] The electromagnetic iron remover of the utility model is arranged at a station between the sintering furnace and the material pouring device, and includes a frame, a driving part installed on the frame, and an electromagnet fixed on the driving part, and the electromagnet is flexibly connected to the driving part through a connecting part. When in use, the frame is arranged at a position after the sintering furnace is discharged from the furnace, and the driving part drives the electromagnet to descend close to the surface of the material to adsorb magnetic foreign matter. The structure is simple, and the electromagnet is flexibly connected to the driving part through a connecting part. When the electromagnet contacts the material or other foreign matter, the collision damage of the electromagnet is reduced, and when the magnetic foreign matter in the material is adsorbed, the foreign matter generated by itself is avoided from flowing into the material, thereby ensuring the quality of the product.

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figure 1 and Figure 2As shown, the electromagnetic iron remover of this embodiment is arranged at a station between the sintering furnace and the material pouring device, and includes a frame 1, a driving member 2 mounted on the frame 1, and an electromagnet 3 fixedly connected to the driving member 2, and the electromagnet 3 is flexibly connected to the driving member 2 through a connecting member 4. When in use, the frame 1 is set at a position after the sintering kiln is taken out of the furnace. When the calcining bowl is transported to this station, the electromagnet 3 is energized, and the driving member 2 drives the electromagnet 3 to descend close to the surface of the material to adsorb magnetic foreign matter. Its structure is simple, and the electromagnet 3 is flexibly connected to the driving member 2 through the connecting member 4. When the electromagnet 3 contacts the material or other foreign matter, the collision and damage of the electromagnet 3 is avoided, so that the foreign matter produced by itself falls into the material, thereby ensuring the quality of the product.

[0023] The electromagnetic iron remover of the utility model can be installed at any position between the sintering furnace and the bowl inverting device. By arranging the electromagnetic iron remover at this workstation, it is possible to timely discover whether the upstream equipment has abnormal rust by observing whether the adsorbed foreign matter contains rust, so as to facilitate timely repair and maintenance. In addition, the electromagnetic iron remover of the utility model can also be directly installed on the bowl separator. When installed on the bowl separator, the upgraded cylinder of the bowl separator itself can be used, thereby eliminating the driving part 2 in the utility model and simplifying the structure.

[0024] In this embodiment, the driving member 2 is configured as a double-axis cylinder, and the end of the piston rod of the double-axis cylinder is fixedly connected with a balance plate 5. In this structure, the double-axis cylinder operates stably, and the end of its piston rod is bolted to the balance plate 5. The balance plate 5 is provided to ensure the level of the electromagnet 3 and improve the adsorption effect.

[0025] In this embodiment, the connecting member 4 includes four chains 43, one end of each chain 43 is connected to the electromagnet 3, and the other end is fixedly connected to the balance board 5. The electromagnet 3 is connected to the balance board 5 through the chain 43, which not only realizes a flexible connection but also ensures the firmness of the connection. The four chains 43 are connected to the four corners of the rectangular electromagnet 3, and the connection is stable. In other embodiments, the connecting member 4 should include at least three chains 43 to ensure the stability of the structure.

[0026] In this embodiment, the connecting member 4 includes four adjusting bolts 41 and nuts 42. Each adjusting bolt 41 is passed through the balance plate 5 and is locked and fixed by the nut 42. The chain 43 is fixed to the end of the adjusting bolt 41. In this structure, four adjusting bolts 41 are provided to facilitate adjustment of the installation height of the chain 433, so as to accurately adjust the level of the electromagnet 3, thereby ensuring the adsorption effect. The adjusting bolt 41 is locked and fixed on the balance plate 5 by the nut 42, and the connection is firm and easy to disassemble.

[0027] In this embodiment, a threaded hole matching the adjusting bolt 41 is provided on the balancing plate 5. In this structure, the adjusting bolt 41 is threadedly connected to the threaded hole, which further ensures the connection strength between the adjusting bolt 41 and the balancing plate 5, making it difficult to loosen. In addition, compared with direct perforation connection, threaded connection also makes it easier to adjust the adjusting bolt 41.

[0028] In this embodiment, the electromagnet 3 is provided with a lifting ring 6 fixedly connected to the chain 43, and the lifting ring 6 is threadedly connected to the electromagnet 3. In this structure, the lifting ring 6 threadedly connected to the outer shell of the electromagnet 3 is fixedly connected to the chain 43, which is convenient for disassembly of the electromagnet 3 and convenient for cleaning.

[0029] In this embodiment, a coating 31 is sprayed on the outer surface of the electromagnet 3, and the coating 31 is set as a Teflon coating. In this structure, the coating 31 made of Teflon material can prevent the electromagnet 3 from contacting metal wear with materials or foreign objects, further ensuring the quality of the product.
