Description

Technical Field

[0001] This utility model relates to the field of magnetic separation of solid materials, and in particular to an automatic device for removing micron-sized metallic foreign matter from lithium iron phosphate powder. Background Technology

[0002] Currently, domestic enterprises mostly use electromagnetic separators to remove ferromagnetic impurities from non-magnetic materials. Commonly used electromagnetic separators on the market mainly include electromagnetic separators and permanent magnet separators to efficiently remove ferromagnetic impurities mixed in materials. However, traditional separators lack cleaning devices. When too much ferromagnetic material is adsorbed on the magnetic rod, the magnetic rod's adsorption force for subsequent ferromagnetic materials will weaken. At this time, it is necessary to stop the machine and manually clean the ferromagnetic material adsorbed on the magnetic rod, which is time-consuming, labor-intensive, and inefficient. Therefore, an automatic device for removing micron-sized metallic foreign matter from lithium iron phosphate powder is proposed. Utility Model Content

[0003] The purpose of this utility model is to solve any of the problems in the above-mentioned technologies, thereby proposing an automatic device for removing micron-sized metallic foreign objects from lithium iron phosphate powder, including a machine body and a feeding pipe located on its top, a discharging pipe located at the bottom of the machine body, a cover plate installed on the left side of the machine body, a cylinder fixedly installed on the right side of the machine body, a motor fixedly installed on the cover plate, a disc connected to the output end of the motor, a plurality of magnetic rods fixedly installed on the side of the disc away from the motor, and a scraper sleeved on the magnetic rod.

[0004] Furthermore, guide holes are provided at the four corners of one side wall of the body, and guide rods are provided at the four corners of one side wall of the cover plate. The positions of the guide rods correspond to the guide holes, and the guide rods are movably inserted into the guide holes.

[0005] Furthermore, the magnetic rods are arranged in an equidistant ring, and a disc is also installed at the right end of the magnetic rods. The output end of the cylinder is connected to the disc at the right end of the magnetic rods.

[0006] Furthermore, a baffle is provided inside the machine body, the baffle is located on the left side of the discharge pipe, and the scraper is located between the left side wall of the machine body and the baffle.

[0007] Furthermore, a slag discharge pipe is provided at the bottom left side of the baffle, and the scraper is located above the slag discharge pipe.

[0008] Furthermore, the scraper has multiple through holes equidistantly arranged around it, and there are bosses on both sides of the through holes, with the sidewalls of the bosses being beveled.

[0009] Beneficial effects: This utility model uses a scraper fitted onto a magnetic rod, which is then driven by a cylinder to move the magnetic rod left and right. The ferromagnetic impurities adsorbed on the magnetic rod are cleaned by the protrusions on the scraper. The cleaned ferromagnetic impurities are discharged into the machine body through the slag discharge pipe, eliminating the need for manual cleaning and increasing cleaning efficiency. At the same time, as the material falls, the rotating magnetic rod can break up the clumps of material, thus removing magnetic foreign objects mixed in with the clumps. This results in better removal of magnetic foreign objects and higher demagnetization efficiency. Attached Figure Description

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of the present invention.

[0019] The following describes, with reference to the accompanying drawings, an automated device for removing micron-sized metallic foreign matter from lithium iron phosphate powder according to an embodiment of the present invention, such as... Figures 1 to 5As shown, the automatic device for removing micron-sized metallic foreign objects from lithium iron phosphate powder includes a machine body 1 and a feed pipe 101 located on its top. A discharge pipe 102 is provided at the bottom of the machine body 1. A cover plate 3 is installed on the left side of the machine body 1, and a cylinder 2 is fixedly installed on the right side of the machine body 1. A motor 4 is fixedly installed on the cover plate 3. A disc 5 is connected to the output end of the motor 4. Multiple magnetic rods 6 are fixedly installed on the side of the disc 5 away from the motor 4. A scraper 7 is also sleeved on the magnetic rod 6.

[0020] Preferably, guide holes 104 are provided at the four corners of one side wall of the body 1, and guide rods 301 are provided at the four corners of one side wall of the cover plate 3. The position of the guide rods 301 corresponds to the guide holes 104. The guide rods 301 are movably inserted into the guide holes 104. The arrangement of the guide rods 301 and the guide holes 104 can improve the stability of the cover plate 3 when it moves.

[0021] Preferably, the magnetic rods 6 are distributed in a equidistant ring, and a disc 5 is also installed on the right end of the magnetic rods 6. The output end of the cylinder 2 is connected to the disc 5 on the right end of the magnetic rods 6. A bearing is provided at the connection between the output end of the cylinder 2 and the disc 5, and the bearing is fixed on the disc 5 to prevent the disc 5 from rubbing against the output end of the cylinder 2 when it rotates.

[0022] In a specific embodiment: when cleaning ferromagnetic impurities in materials, the material is poured into the machine body 1 through the feed pipe 101, and then the motor 4 is started to drive the disc 5 and the magnetic rods 6 on its side wall to rotate. The magnetic rods 6 adsorb and clean the ferromagnetic impurities contained in the material. At the same time, as the material falls, the rotating magnetic rods 6 can break up the clumps of material, so as to remove the magnetic foreign objects mixed in the clumps of material. The removal effect of magnetic foreign objects is better and the demagnetization efficiency is higher. Among them, the magnetic rods 6 are electromagnets. The current is provided by an external power source to generate a strong electromagnetic field to adsorb and separate metal impurities. Compared with permanent magnet separators, electromagnetic separators have a more powerful working effect and can adsorb and separate more metal impurities. In addition, it has an adjustable magnetic field, a wide range of applications, simple maintenance, and can be flexibly used in different scenarios. It can also realize PLC linkage control to achieve automatic slag discharge and other mechanical automatic integrated operations, which greatly reduces labor costs.

[0023] Preferably, the machine body 1 is provided with a baffle 8, which is located on the left side of the discharge pipe 102, and the scraper 7 is located between the left side wall of the machine body 1 and the baffle 8.

[0024] Preferably, a slag discharge pipe 103 is provided at the bottom left side of the baffle 8, and the scraper 7 is located above the slag discharge pipe 103. Solenoid valves are provided on the feed pipe 101, the discharge pipe 102 and the slag discharge pipe 103 to control their opening and closing.

[0025] Preferably, the scraper 7 has multiple through holes 702 arranged in a circumferential pattern at equal intervals, and protrusions 701 are provided on both sides of the through holes 702, with the sidewalls of the protrusions 701 being inclined surfaces.

[0026] In a specific embodiment: when cleaning the ferromagnetic impurities adsorbed on the magnetic rod 6, the solenoid valve on the feed pipe 101 is controlled to prevent the material from entering the machine body 1 through the feed pipe 101. Then, the cylinder 2 is activated to push the disc 5 and the magnetic rod 6 on its side wall to move to the left. When the magnetic rod 6 moves to the left, it will drive the scraper 7 to move to the left simultaneously. When the scraper 7 contacts the left side wall of the machine body 1, it will be blocked and will not be able to continue to move to the left, while the magnetic rod 6 continues to move to the left, thereby cleaning the material by scraping the magnetic rod 6. The protrusions 701 on plate 7 clean the ferromagnetic impurities adsorbed on magnetic rod 6. At the same time, when cylinder 2 pulls disc 5 and magnetic rod 6 on its side wall to the right, scraper 7 is blocked by baffle 8 inside machine body 1, causing relative movement between scraper 7 and magnetic rod 6. Thus, the protrusions 701 on scraper 7 clean the ferromagnetic impurities adsorbed on magnetic rod 6 again. The cleaned ferromagnetic impurities are discharged into machine body 1 through slag discharge pipe 103. No manual cleaning is required, and the cleaning efficiency is higher.

[0027] In this embodiment, the control panel 101 is mainly a conventional method for those skilled in the art, and its circuit connections will not be described in detail.

[0028] Working Principle: During operation, material is poured into the machine body 1 through the feed pipe 101. Then, the motor 4 is started, driving the disc 5 and the magnetic rods 6 on its sidewalls to rotate. The magnetic rods 6 adsorb and clean the ferromagnetic impurities contained in the material. Simultaneously, as the material falls, the rotating magnetic rods 6 break up any clumps of material, thus removing magnetic foreign objects trapped within the clumps. This results in better removal of magnetic foreign objects and higher demagnetization efficiency. When it is necessary to clean the ferromagnetic impurities adsorbed on the magnetic rods 6, the solenoid valve on the feed pipe 101 is controlled to prevent material from entering the machine body 1 through the feed pipe 101. Then, the cylinder 2 is activated, pushing the magnetic rods 6 on the disc 5 and its sidewalls... When the magnetic rod 6 moves to the left, it drives the scraper 7 to move to the left simultaneously. When the scraper 7 comes into contact with the left side wall of the machine body 1, it will be blocked and will not be able to continue moving to the left, while the magnetic rod 6 continues to move to the left. Thus, the ferromagnetic impurities adsorbed on the magnetic rod 6 are cleaned by the protrusion 701 on the scraper 7. At the same time, when the cylinder 2 pulls the disc 5 and the magnetic rod 6 on its side wall to the right, the scraper 7 will be blocked by the baffle 8 inside the machine body 1, causing the scraper 7 and the magnetic rod 6 to move relative to each other. Thus, the ferromagnetic impurities adsorbed on the magnetic rod 6 are cleaned again by the protrusion 701 on the scraper 7. The cleaned ferromagnetic impurities will be discharged into the machine body 1 through the slag discharge pipe 103, eliminating the need for manual cleaning and improving cleaning efficiency.
