Description

Technical Field

[0001] This application relates to the technical field of battery production and manufacturing. Specifically, it relates to a permanent magnet device for collecting enriched materials. Background Art

[0002] In the production process of lithium batteries, the positive electrode material is an important component of lithium-ion batteries. Its production process is complex and involves a large number of processing equipment. During this process, if magnetic foreign objects (such as iron filings) enter the positive electrode material, it will reduce the quality and safety of the battery. Therefore, the collection and removal of magnetic foreign objects (i.e., enriched materials) from the positive electrode material is an important process in battery production.

[0003] In the prior art, a permanent magnet device can collect enriched materials. The existing permanent magnet device usually includes a magnetic rod and a magnetic rod sleeve outside the magnetic rod. The magnetic rod sleeve plays a protective role for the magnetic rod. When the magnetic rod sleeve collects a certain amount of enriched materials, its adsorption capacity will significantly decrease. At this time, the magnetic rod sleeve needs to be replaced. In the existing permanent magnet device, due to the fixed setting of the magnetic rod, the replacement time of the magnetic rod sleeve is long, which further leads to a long production stagnation time of the production line, greatly reducing the production capacity and production efficiency.

[0004] Therefore, it is necessary for the inventor to design a new permanent magnet device for collecting enriched materials to overcome the above problems. Summary of the Invention

[0005] The main purpose of this application is to provide a permanent magnet device for collecting enriched materials to solve the problem of the long replacement time of the magnetic rod sleeve in the related art.

One end of each connecting rod penetrates through the side wall of the material passing cylinder and is fixedly connected to the end of a magnetic rod. The driving member drives all the connecting rods to move axially.

[0011] Preferably, the driving member includes a cylinder and a connecting plate. The other ends of all the connecting rods are fixedly connected to the connecting plate, and the telescopic part of the cylinder is fixedly connected to the connecting plate.

[0031] As shown Figures 1 to 4 In the figure, a permanent magnet device for collecting enriched materials includes a material passing cylinder 1, a sealing cover 2, a plurality of magnetic rods 3 and a driving mechanism, wherein: all the magnetic rods 3 are arranged in parallel in the inner cavity of the material passing cylinder 1, and a magnetic rod sleeve 4 is sleeved outside the magnetic rod 3; the sealing cover 2 is detachably connected to one side of the material passing cylinder 1 and is perpendicular to the axial direction of the magnetic rod 3; the driving mechanism is used to drive the magnetic rod 3 to move axially.

[0032] Specifically, the positive electrode material of the battery passes through the material passing cylinder 1 from top to bottom. During this process, the enriched materials in the positive electrode material are attracted by the magnetic rod 3 and adsorbed on the sleeve of the magnetic rod 3. When there is too much enriched material on the sleeve of the magnetic rod 3, the adsorption force of the enriched material on the sleeve of the magnetic rod 3 decreases. At this time, it is necessary to replace the sleeve of the magnetic rod 3. First, stop the equipment, then remove the sealing cover 2 from the material passing cylinder 1, and then use the driving mechanism to push the magnetic rod 3 together with the sleeve of the magnetic rod 3 outwards, which is convenient for the operator to remove the sleeve of the magnetic rod 3 from the magnetic rod 3. After replacing the new sleeve of the magnetic rod 3, use the driving mechanism to reset the magnetic rod 3, and then reinstall the sealing cover 2, thus completing the replacement of the entire sleeve of the magnetic rod 3. In the actual operation process, a skilled worker can complete the replacement of the sleeve of the magnetic rod 3 in more than ten seconds. In this embodiment, by setting the driving mechanism to push the magnetic rod 3 outwards and then replacing the sleeve of the magnetic rod 3, the efficiency of replacing the sleeve of the magnetic rod 3 is greatly improved. Compared with the existing permanent magnet device with the magnetic rod 3 fixedly installed, the downtime of the equipment is greatly reduced, and the production capacity and production efficiency are improved.

[0033] The driving mechanism includes a driving member and a plurality of connecting rods 5. One end of each connecting rod 5 penetrates through the side wall of the material passing cylinder 1 and is fixedly connected to the end of a magnetic rod 3. The driving member drives all the connecting rods 5 to move axially. The driving member includes a cylinder 6 and a connecting plate 7. The other ends of all the connecting rods 5 are fixedly connected to the connecting plate 7, and the telescopic part of the cylinder 6 is fixedly connected to the connecting plate 7.

[0034] Specifically, the telescopic movement of the telescopic part of the cylinder 6 drives the connecting plate 7 to move, the connecting plate 7 drives the connecting rods 5 to move, and the connecting rods 5 drive the magnetic rod 3 to move axially. There is a through hole on the side wall of the material passing cylinder 1 through which the connecting rod 5 can pass. In actual use, a sealing member needs to be set at the through hole to prevent the positive electrode material from leaking out through the through hole.

[0035] A receiving box 8 is fixedly arranged on the outer wall of one side of the material passing cylinder 1 opposite to the sealing cover 2. The connecting rod 5 and the connecting plate 7 are both located in the receiving box 8. The air cylinder 6 is fixedly arranged on the outer wall of the receiving box 8. The telescopic part of the air cylinder 6 penetrates through the outer wall of the receiving box 8 and is fixedly connected to the connecting plate 7. Specifically, by arranging both the connecting rod 5 and the connecting plate 7 in the receiving box 8, the connecting rod 5 and the connecting plate 7 are protected to prevent dust and other dirt from falling on the connecting rod 5 and entering the material passing cylinder 1 along with the connecting rod 5.

[0036] There are two air cylinders 6 in total, and the two air cylinders 6 are symmetrically arranged at both ends on the same side of the connecting plate 7. The two air cylinders 6 and the connecting rod 5 are located on the same side of the connecting plate 7, and the two air cylinders 6 are located on both sides of the material passing cylinder 1. Specifically, this setting method can make the movement of the connecting plate 7 more balanced in force, and the connecting rod 5 can pass through the through hole on the side wall of the material passing cylinder 1 more smoothly. At the same time, the air cylinders 6 located on both sides of the material passing cylinder 1 make the overall floor area of the equipment smaller.

[0037] The sealing cover 2 is fixedly connected to the material passing cylinder 1 through a buckle member 9. Specifically, the buckle member 9 makes the disassembly and assembly of the sealing cover 2 and the material passing cylinder 1 more convenient, and improves the efficiency of replacing the magnetic rod sleeve 4.

[0038] Connecting flanges 10 are fixedly arranged at both the upper and lower ends of the material passing cylinder 1. Specifically, the material passing cylinder 1 is fixedly connected to other structures on the material passing channel of the positive electrode material through the connecting flanges 10.

[0039] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
