Technical Field
[0001] This utility model relates to the field of metal powder impurity removal technology, specifically a magnetic separation device for metal powder impurity removal. Background Technology
[0002] Iron powder is one of the most important metal powders in the powder metallurgy industry. It is used in the largest quantity in powder metallurgy production, accounting for about 85% of the total consumption of metal powders. The main market for iron powder is the manufacture of mechanical parts, which requires about 80% of the total iron powder production. In the processing of iron powder, magnetic separation devices are needed to filter the impurities contained in the iron powder.
[0003] A prior patent (publication number: CN222446813U) discloses a magnetic separation device for removing impurities from metal powder, comprising a support device, a rotating device, and a vibrating device. The vibrating device is mounted on the support device and connected to the rotating device. The rotating device includes a storage box, an impurity slide rail, a rotating chamber, a passive gear ring, a first motor, and an active gear ring. The rotating device drives the iron powder to rotate, facilitating the removal of impurities from the iron powder. The vibrating device causes the impurities in the rotating device to vibrate, thereby accelerating the shaking off of non-metallic impurities from the iron powder, improving the impurity removal effect of the iron powder and the practicality of the device.
[0004] However, the above technical solutions still have certain defects. In the process of removing impurities, the metal powder and non-metal powder are separated by magnetic attraction and vibration. However, the particle size and density of metal powder and non-metal powder are very fine. Therefore, some non-metal powder and metal powder will stick together due to static electricity. Then, as the metal powder is magnetically attracted, the metal powder and non-metal powder cannot be fully separated. Therefore, a magnetic separation device for removing impurities from metal powder is proposed. Utility Model Content
[0005] Therefore, the purpose of this utility model is to provide a magnetic separation device for removing impurities from metal powder, so as to solve the technical problems mentioned in the background.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a magnetic separation device for removing impurities from metal powder, comprising a sorting mechanism, the sorting mechanism comprising an outer cylinder, a plurality of fans fixedly connected to one side of the outer cylinder, a first motor fixedly connected to the side wall of the outer cylinder, a high-pressure magnetic disk extending into the outer cylinder fixedly connected to the output end of the first motor, a plurality of through holes being formed on the outer wall of the high-pressure magnetic disk, a scraper fixedly connected to the inner wall of the outer cylinder, the edge of the scraper abutting against the side wall of the high-pressure magnetic disk, a hatch hinged to the bottom of the outer wall of the outer cylinder, a pin slidably fitted onto the outer wall of the outer cylinder, the outer wall of the pin abutting against the outer wall of the hatch.
[0007] As a preferred technical solution, a feeding mechanism is fixedly connected to the top of the outer cylinder. The feeding mechanism includes a feeding bin, which is connected to the inner wall of the outer cylinder. A sealing cover is fitted onto the top of the feeding bin.
[0008] As a preferred technical solution, a material distribution plate is slidably connected to the inner wall of the feeding hopper, a second motor is fixedly connected to the side wall of the feeding hopper, an eccentric wheel is fixedly connected to the output end of the second motor, a sliding frame is fixedly connected to one end of the material distribution plate, and the sliding frame is slidably sleeved on the outer wall of the eccentric wheel.
[0009] As a preferred technical solution, a filtering mechanism is fixedly connected to the end of the outer cylinder away from the first motor. The filtering mechanism includes a collection chamber, which is fixedly connected to the end of the outer cylinder.
[0010] As a preferred technical solution, a connecting pipe is connected to one side of the top of the collection chamber, the top of the connecting pipe is connected to the inside of the outer cylinder, and an air outlet is opened on the side of the top of the collection chamber away from the connecting pipe.
[0011] As a preferred technical solution, a filter bag is fixedly connected to the inner wall of the collection chamber, and the filter bag is located below the air outlet.
[0012] As a preferred technical solution, the bottom end of the collection chamber is hinged with a flap, the flap is provided with a torsion spring at the connection between the flap and the collection chamber, the top end of the flap is hinged with a pull rod, and the top end of the pull rod is hinged to the inner wall of the filter bag.
[0013] In summary, the present invention has the following main advantages:
[0014] 1. This utility model achieves a more thorough separation of metal powder from metal powder when metal powder and non-metal powder are scattered simultaneously. The non-metal powder is lighter and the metal powder is heavier. Due to the adsorption capacity of the strong magnetic disk, the non-metal powder can be separated from the metal powder more completely. Then, the metal powder adsorbed on the side wall of the strong magnetic disk is scraped off by the scraper and collected inside the outer cylinder. This makes the separation of metal powder more efficient and thorough, thus improving the efficiency of metal powder sorting.
[0015] 2. This utility model uses airflow to pass through the filter bag, allowing non-metallic powder to be filtered out. When the flip plate is turned over, the inside of the filter bag can be flipped out, allowing the non-metallic powder collected inside the filter bag to be poured out. This makes the cleaning of non-metallic powder more convenient and efficient. Furthermore, during the operation of the feeding mechanism, the reciprocating sliding of the material distribution plate allows the metal powder to be sorted to be evenly distributed into the inner cylinder, resulting in better sorting effect.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0025] The embodiments of this utility model will be described below based on its overall structure.
[0026] A magnetic separation device for removing impurities from metal powder, such as Figures 1 to 5 As shown, the system includes a sorting mechanism 1, which includes an outer cylinder 101. Multiple sets of fans 102 are fixedly connected to one side of the outer cylinder 101. A first motor 103 is fixedly connected to the side wall of the outer cylinder 101. A high-pressure disk 104 extending into the outer cylinder 101 is fixedly connected to the output end of the first motor 103. Multiple sets of through holes are opened on the outer wall of the high-pressure disk 104. A scraper 105 is fixedly connected to the inner wall of the outer cylinder 101. The edge of the scraper 105 is attached to the side wall of the high-pressure disk 104. A hatch 4 is hinged to the outer wall of the outer cylinder 101 near the bottom. A pin 5 is slidably sleeved on the outer wall of the outer cylinder 101. The outer wall of the pin 5 abuts against the outer wall of the hatch 4.
[0027] The top of the outer cylinder 101 is fixedly connected to the feeding mechanism 2, which includes a feeding bin 201. The feeding bin 201 is connected to the inner wall of the outer cylinder 101. The top of the feeding bin 201 is fitted with a sealing cover. The inner wall of the feeding bin 201 is slidably connected to a distribution plate 202. The side wall of the feeding bin 201 is fixedly connected to a second motor 203. The output end of the second motor 203 is fixedly connected to an eccentric wheel 204. One end of the distribution plate 202 is fixedly connected to a sliding frame 205, which is slidably fitted onto the outer wall of the eccentric wheel 204.
[0028] By adding sorted metal powder into the feeding hopper 201, the second motor 203 drives the eccentric wheel 204 to rotate, which in turn pushes the sliding frame 205, causing the distributing plate 202 to slide back and forth on the inner wall of the feeding hopper 201. This allows the metal powder added to the feeding hopper 201 to pass through the distributing plate 202, thus enabling the metal powder to be evenly and slowly transported and scattered into the outer cylinder 101. The first motor 103 drives the high-pressure disk 104 to rotate, while the fan 10... 2. An airflow is blown into the outer cylinder 101, causing the non-metallic powder in the metal powder to be carried into the collection chamber 301 by the airflow. The metal powder is attracted by the magnetic disk 104. As the magnetic disk 104 rotates, the magnetically attracted metal powder comes into contact with the scraper 105, causing the scraper 105 to scrape the metal powder off the magnetic disk 104, thereby collecting the metal powder at the bottom of the inner wall of the outer cylinder 101. By pulling the latch 5 and flipping the hatch 4, the sorted metal powder inside the outer cylinder 101 can be collected.
[0029] Please refer to this carefully. Figure 1 , Figure 3 and Figure 5 A filter mechanism 3 is fixedly connected to the end of the outer cylinder 101 away from the first motor 103. The filter mechanism 3 includes a collection chamber 301, which is fixedly connected to the end of the outer cylinder 101. A connecting pipe 302 is connected to one side of the top of the collection chamber 301. The top of the connecting pipe 302 is connected to the interior of the outer cylinder 101. An air outlet 303 is provided on the side of the top of the collection chamber 301 away from the connecting pipe 302. A filter bag 304 is fixedly connected to the inner wall of the collection chamber 301. The filter bag 304 is located below the air outlet 303. A flap 305 is hinged to the bottom of the collection chamber 301. A torsion spring is provided at the connection between the flap 305 and the collection chamber 301. A pull rod 306 is hinged to the top of the flap 305. The top of the pull rod 306 is hinged to the inner wall of the filter bag 304.
[0030] After the airflow carries the non-metallic powder into the collection chamber 301, the airflow passes through the filter bag 304, causing the non-metallic powder to be filtered out by the filter bag 304. Then the airflow passes through the air outlet 303. After the sorting is completed, the flap 305 is pushed to flip, causing the flap 305 to pull the filter bag 304 through the pull rod 306, thereby pulling the inner wall of the filter bag 304 out of the collection chamber 301. At this time, the non-metallic powder filtered out of the filter bag 304 naturally falls out, making it more convenient and faster to clean the non-metallic powder.
[0031] In use, when metal powder and non-metal powder are scattered simultaneously, the non-metal powder is lighter and the metal powder is heavier. Due to the adsorption capacity of the strong disk 104, the non-metal powder can be separated from the metal powder more thoroughly. Then, the metal powder adsorbed on the side wall of the strong disk 104 is scraped off by the scraper 105 and collected inside the outer cylinder 101. This makes the separation of metal powder more efficient and thorough, improving the efficiency of metal powder sorting. The parts of this device not mentioned are the same as or can be implemented using existing technology.
