Description

Technical Field

[0001] This utility model relates to a dry electromagnetic powder iron remover, belonging to the field of dry electromagnetic powder iron removal technology. Background Technology

[0002] For dry powder materials such as quartz sand, potassium-sodium feldspar, and lithium battery positive and negative electrode materials in industries like mineral processing, ceramics, and new energy batteries, iron impurities such as metallic iron or stainless steel are often introduced during production. These iron impurities severely affect the quality of the materials. Currently, the industry commonly uses dry powder electromagnetic separators, which feature high magnetic field strength, a large magnetic field gradient, and strong adsorption capacity for iron impurities. These separators effectively remove iron impurities from the materials being processed, achieving the goal of purifying dry powder materials. Dry powder electromagnetic separators utilize alternating periods of magnetic field presence and absence to ensure that iron impurities in the materials are either attracted or not attracted by the magnetic force, thus sequentially discharging the dry powder material and the iron impurities, achieving the purpose of screening and removing iron impurities.

[0003] Chinese utility model patent CN221311022U discloses a high-field-strength fully automatic dry powder electromagnetic separator. A magnetic mesh assembly is installed at the bottom of the feed hopper, and an electromagnetic coil is installed inside the casing. The magnetic mesh assembly is located inside the electromagnetic coil, and a three-way discharge valve is installed at the bottom of the magnetic mesh assembly. A dual-path powder discharge box structure is installed at one discharge port of the three-way discharge valve. This utility model uses two discharge pipes to alternately discharge powder, which is beneficial for alternately conveying dry powder into dry powder packaging bags.

[0004] However, the above-mentioned patent has the following defects in actual use: First, when the material falls from the hopper into the magnetic channel, the material undergoes free fall and the speed gradually increases. Therefore, iron impurities are more likely to be captured at the upper end of the magnetic channel. Moreover, as the material falls to the lower end of the magnetic channel, the amount of iron impurities decreases. Thus, more iron impurities are adsorbed at the upper end of the magnetic channel than at the lower end. Second, some powder materials are prone to agglomeration after being squeezed during placement. After agglomeration, the iron impurities in the lumpy material cannot be adsorbed.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This utility model addresses the shortcomings of the prior art by providing a dry electromagnetic powder iron remover, which allows powder to be discharged from different heights of the magnetic suction cylinder, resulting in more uniform dispersion, higher iron impurity removal rate, and more uniform adsorption of iron impurities onto the inner wall of the magnetic suction cylinder.

[0007] To solve the above technical problems, the present invention adopts the following technical solution:

[0008] A dry electromagnetic powder iron remover includes a frame, a magnetic suction cylinder with openings at the top and bottom is fixed in the middle of the frame, and an electromagnetic coil is wound around the outer ring of the magnetic suction cylinder.

[0009] A discharge cylinder is coaxially installed inside the magnetic suction cylinder. The outer wall of the discharge cylinder is set with a certain gap from the inner wall of the magnetic suction cylinder. An upper discharge port is provided near the upper end of the outer wall of the discharge cylinder, and a lower discharge port is provided at the lower end of the outer wall of the discharge cylinder.

[0010] The lower edge of the upper discharge port is inclined with an upper guide plate, and the lower edge of the lower discharge port is inclined with a lower guide plate; the upper guide plate is a conical plate with an opening at the top, and the lower guide plate is a conical plate, which blocks the lower end of the discharge cylinder.

[0011] Furthermore, a connecting plate is provided on the upper side of the upper guide plate and the lower guide plate, and the upper guide plate and the lower guide plate are fixed to the inner wall of the discharge cylinder by the connecting plate.

[0012] Furthermore, the upper end of the discharge cylinder is provided with a feed hopper, and a mesh plate is provided at the junction of the feed hopper and the discharge cylinder, with material leakage holes evenly distributed on the mesh plate.

[0013] Furthermore, the feed hopper is connected to a vibration device.

[0014] Furthermore, the vibration device includes a vibrating plate fixedly connected to the feed hopper, and the lower end of the vibrating plate is provided with four protrusions, which are arranged in a ring at equal angles.

[0015] A turntable is rotatably mounted on the top plate of the frame via bearings. Four rollers are rotatably mounted on the turntable, protruding from the upper surface of the turntable and arranged in a ring at equal angles. The position of the rollers is adapted to the protrusion of the vibrating plate.

[0016] Furthermore, a plurality of sliding rods are fixed on the lower surface of the vibrating plate, and the vibrating plate is slidably mounted on the upper plate via the sliding rods. A spring is fitted onto the sliding rods at the lower section of the upper plate.

[0017] Furthermore, a pulley is rotatably mounted on the top plate, and the pulley is driven by a drive mechanism via a belt drive and a turntable.

[0018] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0019] An upper guide plate is inclined at the lower edge of the upper discharge port of the discharge cylinder, and a lower guide plate is inclined at the lower edge of the lower discharge port of the discharge cylinder. The powder material enters from the upper end of the discharge cylinder. A portion of the material near the inner wall of the discharge cylinder is discharged from the upper discharge port due to the obstruction of the upper guide plate. The material near the middle of the discharge cylinder flows to the lower end through the opening in the middle of the upper guide plate and is discharged from the lower discharge port. This allows the powder to be discharged from different heights of the magnetic suction cylinder, resulting in more uniform dispersion, a higher iron impurity removal rate, and more uniform adsorption of iron impurities onto the inner wall of the magnetic suction cylinder.

[0020] A screen is installed at the junction of the feed hopper and the discharge cylinder. The feed hopper is connected to a vibrating device. The vibrating device drives the feed hopper, screen, and discharge cylinder to vibrate together, causing the clumped powder to impact the screen and thus crush the material.

Detailed Implementation

[0027] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0028] like Figure 1 As shown, this utility model provides a dry electromagnetic powder iron remover, including a frame 1, a magnetic suction cylinder 2 with openings at the top and bottom is fixed in the middle of the frame 1, and an electromagnetic coil 4 is wound around the outer ring of the magnetic suction cylinder 2.

[0029] A discharge cylinder 7 is coaxially installed inside the magnetic suction cylinder 2. The outer wall of the discharge cylinder 7 is set with a certain gap from the inner wall of the magnetic suction cylinder 2. An upper discharge port 10 is provided around the upper end of the outer wall of the discharge cylinder 7, and a lower discharge port 12 is provided at the lower end of the outer wall of the discharge cylinder 7.

[0030] The lower edge of the upper discharge port 10 is inclined with an upper guide plate 8, and the lower edge of the lower discharge port 12 is inclined with a lower guide plate 11; the upper guide plate 8 is a conical plate with an open top, such as... Figure 3 The lower guide plate 11 is conical and blocks the lower end of the discharge cylinder 7. Powder material enters from the upper end of the discharge cylinder 7. A portion of the material near the inner wall of the discharge cylinder 7 is discharged from the upper outlet 10 due to the obstruction of the upper guide plate 8. The material near the middle of the discharge cylinder 7 flows to the lower end through the opening in the middle of the upper guide plate 8 and is discharged from the lower outlet 12. This allows the powder to be discharged from different heights in the magnetic suction cylinder 2, resulting in more uniform dispersion, a higher iron impurity removal rate, and more uniform adsorption of iron impurities onto the inner wall of the magnetic suction cylinder 2.

[0031] A connecting plate 9 is also provided on the upper side of the upper guide plate 8 and the lower guide plate 11. The upper guide plate 8 and the lower guide plate 11 are fixed to the inner wall of the discharge cylinder 7 by the connecting plate 9.

[0032] The upper end of the discharge cylinder 7 is provided with a feed hopper 3, and a mesh plate 6 is provided at the junction of the feed hopper 3 and the discharge cylinder 7. The mesh plate 6 is provided with evenly distributed leakage holes.

[0033] The feed hopper 3 is connected to the vibration device, which drives the feed hopper 3, the screen plate 6 and the discharge cylinder 7 to vibrate together, causing the clumped powder to hit the screen plate 6 and thus crush the material.

[0034] The vibration device includes a vibrating plate 13 fixedly connected to the feed hopper 3. The lower end of the vibrating plate 13 is provided with four protrusions 14, such as... Figure 2 Four protrusions 14 are arranged in a ring at equal angles. A turntable 15 is rotatably mounted on the top panel 5 of the frame 1 via bearings. Four rollers 16 are rotatably mounted on the turntable 15, protruding from the upper surface of the turntable 15 and arranged in a ring at equal angles. The position of the rollers 16 corresponds to the protrusions 14 of the vibrating plate 13. During the rotation of the turntable 15, when the rollers 16 rotate to directly below the protrusions 14, they lift the vibrating plate 13. After passing the protrusions 14, the vibrating plate 13 falls. When the turntable 15 rotates rapidly, it causes the vibrating plate 13 to vibrate up and down.

[0035] Multiple sliding rods 17 are fixed to the lower surface of the vibrating plate 13. The vibrating plate 13 is slidably mounted on the upper panel 5 via the sliding rods 17. A spring is fitted onto the lower section of the upper panel 5 of the sliding rods 17. When the roller 16 rotates past the protrusion 14, the sliding rods 17 pull down the vibrating plate 13 under the action of the spring, causing it to quickly return to its original position.

[0036] A pulley 18 is also rotatably mounted on the upper panel 5. The pulley 18 is driven by the turntable 15 via belt drive. The pulley 18 is driven by a drive mechanism (not shown in the figure).

The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
