Abstract
Description
Technical Field
[0001] This utility model relates to the field of powder metallurgy technology, specifically to a flip-type iron powder impurity removal device. Background Technology
[0002] Metallurgy refers to the process and technology of extracting metals or metal compounds from minerals and processing them into metallic materials with certain properties using various processing methods. In the extraction of iron powder, it is necessary to separate the iron powder from the surrounding ore powder and slag to remove impurities, so as to facilitate the subsequent purification of the iron powder ore.
[0003] Patent CN215744082U discloses a powder metallurgy iron powder impurity removal device, which uses an electromagnet to attract metal powder, preventing impurities in the metal powder from remaining on the inclined upper and lower separation plates, thus achieving separation between the metal powder and impurities. This separation method is simple and reliable. However, in practice, although the upper and lower separation plates are inclined, iron powder, being a powdery substance, cannot roll smoothly off the plates like particulate impurities, leaving some iron powder residue. When excessive iron powder accumulates, subsequent impurities are blocked and cannot slide off, affecting the subsequent impurity removal effect. Therefore, regular cleaning of the separation plates is necessary, which is time-consuming and labor-intensive. Utility Model Content
[0004] This utility model addresses the shortcomings of existing technologies by providing an automatic material feeding and length-determining circular saw, thereby improving cutting efficiency.
[0005] This utility model is achieved through the following technical solution: a flip-type iron powder impurity removal device includes a box body with a feed inlet at the top. A rectangular plate-shaped electromagnet is installed inside the box body. First rotating shafts are fixed to both ends of the electromagnet along its length. The electromagnet is rotatably connected to the two side walls of the box body along its length via the first rotating shafts. A first motor driving the first rotating shafts is installed on the outer wall of the box body. A discharge plate is installed below the electromagnet. Second rotating shafts are fixed to both ends of the discharge plate along its length. The discharge plate is rotatably connected to the two side walls of the box body along its length via the second rotating shafts. A second motor driving the second rotating shafts is installed on the outer wall of the box body. Discharge troughs are fixed to both side walls along the width direction of the box body. The discharge troughs are inclined, with the upper end located below the discharge plate and on the rotation path of the discharge plate, and the lower end located outside the box body.
[0006] This design uses a first motor to drive an electromagnet, which is plate-shaped. During use, iron powder is placed on the upper surface of the electromagnet through the feed inlet. The electromagnet attracts the iron powder, and then the first motor drives the electromagnet to rotate 180°, suspending the iron powder completely and allowing particulate impurities to fall freely, resulting in better impurity removal. Furthermore, two discharge troughs are located on the rotation path of the discharge plate. A second motor rotates the discharge plate, allowing the two discharge troughs to be connected separately. These troughs are used to discharge impurities and iron powder respectively, making the design convenient to use.
[0007] As an optimization, retaining rings are fixedly installed on the edges of both the upper and lower surfaces of the electromagnet. This optimization design uses retaining rings to facilitate the placement of iron powder on the electromagnet, preventing the iron powder from spilling when the electromagnet is not energized.
[0008] As an optimization, the longitudinal section of the retaining ring is frustoconical.
[0009] As an optimization, the first rotating shaft is a hollow shaft, and the output end of the first motor is fixedly connected to one of the first rotating shafts. The power cable of the electromagnet passes through the cavity of the other first rotating shaft and extends to the outside. This optimized solution facilitates the connection of the power cable to the electromagnet inside the housing.
[0010] As an optimization, both the first and second rotating shafts are rotatably connected to the side wall of the housing via bearings. This optimization makes the rotation of the first and second rotating shafts smoother.
[0011] As an optimization, both the first and second motors are servo motors. This optimized design features servo motors with forward and reverse rotation capabilities, resulting in more accurate rotation control and better performance.
[0012] The beneficial effects of this invention are as follows: The first motor drives the electromagnet to rotate. The electromagnet is plate-shaped. In use, iron powder is placed on the upper surface of the electromagnet through the feed inlet. The electromagnet attracts the iron powder. After the first motor drives the electromagnet to rotate 180°, the iron powder is completely suspended, allowing particulate impurities to fall freely, resulting in better impurity removal. After the impurities are separated, the electromagnet is de-energized, allowing the suspended iron powder to fall freely without accumulating residue on the electromagnet. This does not affect subsequent impurity removal operations, eliminates the need for regular cleaning, and makes it more convenient to use.
[0013] When discharging impurities and scrap iron, the two discharge troughs are located on the rotation path of the unloading plate. The unloading plate can be rotated by the second motor to connect the two discharge troughs respectively. The two discharge troughs are used to discharge impurities and iron powder respectively, which is convenient to use. Attached Figure Description

[0021] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.
[0022] like Figures 1-5 As shown, a tilting iron powder impurity removal device includes a housing 1 with a feed inlet 2 at the top. A rectangular plate-shaped electromagnet 3 is installed inside the housing 1. In this embodiment, retaining rings 4 are fixedly installed on the edges of both the upper and lower surfaces of the electromagnet 3. The longitudinal section of the retaining rings 4 is frustoconical.
[0023] Both ends of the electromagnet 3 along its length are fixedly connected to a first rotating shaft 5. The electromagnet 3 is rotatably connected to the two side walls of the housing 1 along its length via the first rotating shafts 5. A first motor 7, which drives the first rotating shafts 5 to rotate, is provided on the outer wall of the housing 1. In this embodiment, the first rotating shaft 5 is rotatably connected to the side wall of the housing 1 via a bearing 6. The first rotating shaft 5 is a hollow shaft. The output end of the first motor 7 is fixedly connected to one of the first rotating shafts 5. The power line 12 of the electromagnet 3 passes through the cavity of the other first rotating shaft 5 and extends to the outside of the housing. A support frame is fixedly connected to the outer wall of the housing 1, and the first motor 7 is fixedly mounted on the support frame.
[0024] Below the electromagnet 3 is a discharge plate 8. Both ends of the discharge plate 8 along its length are fixedly connected to second rotating shafts 9. The discharge plate 8 is rotatably connected to the two side walls of the housing 1 along its length via the second rotating shafts 9. A second motor 10, which drives the second rotating shafts 9, is provided on the outer wall of the housing 1. In this embodiment, the second rotating shaft 9 is also rotatably connected to the side wall of the housing 1 via bearings 6. A support frame is fixedly connected to the outer wall of the housing 1, and the second motor 10 is fixedly mounted on the support frame.
[0025] Both the first motor 7 and the second motor 10 are servo motors.
[0026] Both sides of the box body 1 in the width direction are fixed with discharge grooves 11. The discharge grooves 11 are inclined, with the upper end of the discharge groove 11 located below the unloading plate 8 and on the rotation path of the unloading plate 8, and the lower end of the discharge groove 11 located outside the box body 1. In this embodiment, when the unloading plate 8 rotates clockwise, the right end of the unloading plate 8 overlaps with the discharge groove 11 on the right side wall of the box body 1. When the unloading plate 8 rotates counterclockwise, the left end of the unloading plate 8 overlaps with the discharge groove 11 on the left side wall of the box body 1.
[0027] Working principle: In use, iron powder is placed on the upper surface of electromagnet 3. When the electromagnet is energized, it attracts the iron powder. First, the second motor 10 drives the unloading plate 8 to rotate clockwise and tilt, so that the right end of the unloading plate 8 overlaps with the discharge chute 11 on the right side wall of the housing 1. Then, the first motor 7 drives the electromagnet 3 to rotate 180°, so that the iron powder attracted on the upper surface of the electromagnet 3 is completely suspended, and the impurities can fall freely onto the unloading plate 8. The unloading plate 8 guides the impurities to be discharged and collected through the discharge chute 11 on the right side. Then, the second motor 10 drives the unloading plate 8 to rotate counterclockwise and tilt, so that the left end of the unloading plate 8 overlaps with the discharge chute 11 on the left side wall of the housing 1. At this time, the electromagnet 3 is de-energized and demagnetized, and the suspended iron powder falls freely onto the unloading plate 8. The unloading plate 8 guides the iron powder to be discharged and collected through the discharge chute 11 on the left side.
[0028] Furthermore, when the first motor 7 drives the electromagnet 3 to rotate 180°, the lower end face of the electromagnet 3 will rotate to the upper end face to form a new upper end face. While removing impurities, personnel can continue to put iron powder into the new upper end face of the electromagnet 3 and repeat the above impurity removal operation to improve work efficiency.
