Description

Technical Field

[0001] The utility model relates to an automatic fluid demagnetization device, belonging to the technical field of production of positive and negative electrode materials for batteries. Background Art

[0002] The inside of the battery is composed of multiple components, including electrolyte, positive and negative electrode materials, diaphragm, electrode collector, etc. If these components come into contact with magnetic substances, magnetic contamination will occur. When magnetic contamination exceeds a certain standard, it will affect the performance and safety of the battery.

[0003] First, magnetic contamination will affect electrochemical performance. The positive and negative electrode materials of the battery are the embedding and de-embedding of lithium ions in the electrode materials, and this process is achieved through ion transfer in the electrolyte. If the electrolyte is contaminated by magnetic substances, ion transfer will be disturbed, ultimately leading to a decrease in electrochemical performance.

[0004] Secondly, magnetic contamination will affect the safety performance of the battery. Magnetic contamination can cause the failure of internal battery components. For example, the electrode collector will deform, fall off or break due to the influence of magnetic substances, which will cause internal short circuits and other safety hazards in the battery, and may even cause the battery to spontaneously combust or explode.

[0005] As mentioned above, the presence of magnetic materials is a common and serious problem in many industrial and manufacturing processes. These magnetic materials may cause damage to equipment and products, and lead to production line downtime and product quality degradation. Therefore, demagnetization devices have become one of the essential equipment. Utility Model Content

[0008] Furthermore, the lower ends of the two rodless cylinders are fixed by a support plate, and the upper ends thereof are fixedly connected by a connecting plate.

[0009] Furthermore, a material collecting box cylinder and a material collecting box are installed at the lower end of the magnetic rod, and the telescopic rod of the material collecting box cylinder is fixedly connected to the material collecting box by a fixing buckle.

[0010] Furthermore, a material collection box slide rail is installed at the bottom of the material collection box, and the material collection box is slidably matched with the material collection box slide rail.

[0011] Furthermore, the above-mentioned demagnetization device also includes a PLC controller and a solenoid valve electrically connected to the PLC controller. The rodless cylinder and the collecting box cylinder are both equipped with air pipe joints and limit switches. The air pipe joints are connected to the solenoid valve through a compressed air pipe, and the solenoid valve is connected to an external air compressor through a compressed air pipe. At the same time, the limit switch is electrically connected to the PLC controller.

[0012] Furthermore, the upper 1 / 3 of the magnetic rod is a non-magnetic section, and the non-magnetic section is threadedly fixedly connected to the fixing frame.

[0013] Furthermore, the fixing frame includes a fixing frame back plate fixedly connected to the slider via fixing frame fixing bolts, a magnetic bar fixing plate is fixedly connected to the fixing frame back plate, and the magnetic bar is threadedly connected to the magnetic bar fixing plate.

The lower end of the magnetic bar 1 is installed with a collecting box cylinder 4 and a collecting box 5.

[0035] See also Fig. 9 and Fig.10 The telescopic rod of the material collecting box cylinder 4 is fixedly connected to the material collecting box 5 through a fixing buckle 4-2. A material collecting box slide rail 5-1 is installed at the bottom of the material collecting box 5, and the material collecting box 5 is slidably matched with the material collecting box slide rail 5-1.

[0036] See also Fig.11 and Fig.12 The lower ends of the two rodless cylinders 6 are fixed by a support plate 9, and the upper ends thereof are fixedly connected by a connecting plate 8.

[0037] See also Figure 1 The above-mentioned demagnetization device also includes a PLC controller and a solenoid valve electrically connected to the PLC controller. The rodless cylinder 6 and the collecting box cylinder 4 are both equipped with an air pipe joint 7 and a limit switch 6-2. The air pipe joint 7 is connected to the solenoid valve through a compressed air pipe, and the solenoid valve is connected to an external air compressor through a compressed air pipe. At the same time, the limit switch 6-2 is electrically connected to the PLC controller.

[0038] See also Figures 6 to 8 The fixing frame 3 includes a fixing frame back plate 3-3 fixedly connected to the slider 6-3 through a fixing frame fixing bolt 3-2, a magnetic bar fixing plate 3-1 is fixedly connected to the fixing frame back plate 3-3, and the magnetic bar 1 is threadedly connected to the magnetic bar fixing plate 3-1. The upper 1 / 3 of the magnetic bar 1 is a non-magnetic section, and the non-magnetic section is threadedly fixedly connected to the fixing frame 3, which can ensure that there is no magnetic material adsorbed on the top of the magnetic bar 1 and reduce the weight of the magnetic bar.

[0039] See also Figures 3 to 5 The scraper plate 2 includes a scraper support frame 2-2 fixedly connected to the slider 6-3 through a scraper fixing bolt 2-1, and a scraper gasket 2-3 is installed on the scraper support frame 2-2.

[0040] Working principle: The origin of the magnetic bar 1 is inside the fluid equipment, and the origin of the collection box is on one side of the magnetic bar 1; when the fluid equipment is running, the magnetic bar 1 absorbs the magnetic material inside. After a certain period of time, the PLC controller opens the solenoid valve and drives the two rodless cylinders 6 to move, driving the magnetic bar 1 on the fixed frame 3 to rise, and at the same time driving the scraper plate 2 to rise. After reaching the high limit, the collection box cylinder 4 starts to move, pulling the collection box 5 to the bottom of the magnetic bar 1. At this time, the rodless cylinder 6 next to the scraper plate 2 drops, scraping the magnetic material on the magnetic bar 1, so that the magnetic material falls into the collection box 5. After collecting the magnetic material, the collection box cylinder 4 starts to move, pushing the collection box 5 to the side of the magnetic bar 1, reserving space for the magnetic bar 1 to fall to the origin, and the magnetic bar 1 starts to fall, waiting for the next cycle.
