Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of iron removal devices, specifically an iron removal device for stainless steel pipelines used in the production of negative electrode materials. Background Technology
[0002] In the production of lithium-ion battery anode materials, core processes such as raw material transportation, mixing, and grinding must be completed through stainless steel pipelines. Since the raw materials themselves may carry trace amounts of iron impurities, and stainless steel pipelines are prone to wear and corrosion during long-term use, producing iron filings, these iron impurities, if carried into subsequent production stages along with the anode material, can severely affect the battery's electrochemical performance and even cause internal short circuits, threatening safety. Therefore, iron removal is necessary when the anode material is transported through stainless steel pipelines to ensure its purity and improve battery product quality.
[0003] Currently, the mainstream iron removal solution for stainless steel pipes in the industry is the fixed magnetic rod type magnetic iron removal device. This type of device usually uses multiple permanent magnet rods fixed in parallel on the internal support of the pipe. It uses magnetic field to adsorb impurities in the flowing material. However, with the fixed magnetic rod layout, the magnetic field coverage is limited to the area around the magnetic rod. When the negative electrode material flows at high speed in the pipe, some iron impurities are unable to enter the effective magnetic field area due to the short residence time of the material agglomeration and encapsulation, thus reducing the iron removal efficiency. Utility Model Content
[0004] The purpose of this invention is to provide an iron removal device for stainless steel pipelines used in the production of negative electrode materials. This addresses the problem in the background art where the fixed magnetic rod layout limits the magnetic field coverage to the area surrounding the rod. When the negative electrode material flows at high speed within the pipeline, some iron impurities, due to material agglomeration and short residence time, fail to enter the effective magnetic field area and are difficult to adsorb, thus reducing iron removal efficiency. To solve the above technical problems, this invention is achieved through the following technical solution: This utility model relates to an iron removal device for stainless steel pipes used in the production of negative electrode materials, comprising: The iron removal assembly includes a mounting frame, a connecting bracket fixedly provided on the inner wall of the mounting frame, and a rod seat fixedly provided at the bottom end of the mounting frame; A dispersing and screening assembly includes a guide plate and two electromagnetic plates. The electromagnetic plates are disposed at the bottom of the guide plate, and the two sides of the guide plate are rotatably disposed at the top of the inner wall of the connecting frame. An arc-shaped groove is formed at the top of the guide plate. The two electromagnetic plates are fixedly disposed at the top of the inner wall of the connecting frame, and the two electromagnetic plates are arranged in an intersecting manner. Several sieve holes are formed at the top of the electromagnetic plates.
[0005] Preferably, the iron removal assembly further includes a top frame, the bottom end of which is fixedly disposed at the top end of the connecting frame, and the bottom end of the top frame contacts the top end of the guide plate.
[0006] Preferably, the plurality of sieve holes are arranged in a matrix.
[0007] Preferably, the top of the top frame is angled downwards, and the width of the inner wall of the top frame is less than the width of the guide plate.
[0008] Preferably, the iron removal assembly further includes four mounting bases, one side of each of the four mounting bases being fixedly disposed on one of the four sides of the mounting frame.
[0009] Preferably, it further includes an adjusting component, the adjusting component including a lead screw, the outer wall of the lead screw penetrating the top end of the rod seat, a knob fixedly provided at the top end of the lead screw, a horizontal plate rotatably provided at the bottom end of the lead screw, a vertical rod fixedly provided at the top end of the horizontal plate, and the vertical rod being slidably connected to the opposite side of the guide plate.
[0010] Preferably, the adjusting component further includes a slider, one side of which is rotatably disposed on one side of the vertical rod, and the outer wall of the slider is slidably connected to one side of the guide plate.
[0011] Preferably, the tops of the two electromagnetic plates respectively penetrate both sides of the outer wall of the vertical rod.
[0012] This utility model has the following beneficial effects: This invention, by incorporating a guide plate and two electromagnetic plates, slows down the flow rate of material as it passes through the guide plate, which is formed by the arc-shaped groove at its top. The material then passes through the cross-arranged electromagnetic plates and flows downward along the screen holes at their tops. This method disperses the material and prolongs its residence time in the magnetic field area, ensuring thorough separation of the material from iron impurities and thus improving iron removal efficiency.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0018] Please see Figure 1-4 As shown, this utility model is an iron removal device for stainless steel pipes used in the production of negative electrode materials, comprising: The iron removal assembly includes a mounting frame 11, a connecting bracket 12 fixedly provided on the inner wall of the mounting frame 11, and a rod seat 14 fixedly provided at the bottom end of the mounting frame 11. Mounting frame 11 provides a connection support base for the entire device, and the outer wall of connecting frame 12 is fitted with the inner wall of stainless steel pipe.
[0019] The dispersion screening assembly includes a guide plate 21 and two electromagnetic plates 22. The electromagnetic plates 22 are disposed at the bottom of the guide plate 21. The two sides of the guide plate 21 are respectively rotatably disposed at the top of the inner wall of the connecting frame 12. The top of the guide plate 21 is provided with an arc-shaped groove 211. The two sides of the electromagnetic plates 22 are respectively fixedly disposed at the top of the inner wall of the connecting frame 12. The two electromagnetic plates 22 are arranged in an up-down cross pattern, and the top of the electromagnetic plates 22 is provided with a number of sieve holes 221. The guide plate 21, in conjunction with the arc-shaped groove 211, can slow down the material flow rate and prolong the contact time between the material and the electromagnetic plate 22. The electromagnetic plate 22 is set at an angle downward and can generate a magnetic field to adsorb iron impurities in the material.
[0020] The iron removal assembly also includes a top frame 13, the bottom of which is fixedly mounted on the top of the connecting frame 12, and the bottom of the top frame 13 is in contact with the top of the guide plate 21.
[0021] Several sieve holes 221 are arranged in a matrix; The combination of sieve holes and cross-shaped electromagnetic plates can disperse materials and improve iron removal efficiency.
[0022] The top of the top frame 13 is angled downwards, and the width of the inner wall of the top frame 13 is less than the width of the guide plate 21.
[0023] The iron removal assembly also includes four mounting bases 15, one side of each of the four mounting bases 15 being fixedly mounted on one of the four sides of the mounting frame 11; Mounting bracket 15 is used to connect and install the entire iron removal device and stainless steel pipes.
[0024] Working principle: After the iron removal device is installed inside the stainless steel pipe, the material flowing inside the stainless steel pipe passes through the top frame 13 and comes into contact with the guide plate 21. Under the action of the guide plate 21 and the arc-shaped groove 211 opened at its top, the flow rate of the material is slowed down. Then the material flows down with the guide plate 21 to the electromagnetic plate 22. The electromagnetic plate 22 generates a magnetic field to adsorb iron impurities in the material. The remaining material flows down through the screen holes 221, and the other part slides down directly along the surface of the electromagnetic plate 22 to another electromagnetic plate 22. After being adsorbed by the other electromagnetic plate 22, it flows down. In this way, the material can be dispersed and the residence time of the material in the magnetic field area can be extended, so that the material is completely separated from the iron impurities, thereby improving the iron removal efficiency.
[0025] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes: The adjusting component includes a lead screw 31, the outer wall of which passes through the top end of the rod seat 14. A knob 32 is fixedly provided at the top end of the lead screw 31, and a horizontal plate 33 is rotatably provided at the bottom end of the lead screw 31. A vertical rod 34 is fixedly provided at the top end of the horizontal plate 33, and the vertical rod 34 is slidably connected to the opposite side of the guide plate 21. The lead screw 31 is threadedly engaged with the rod seat 14, and the outer wall of the knob 32 is provided with anti-slip threads to increase the friction between the hand and the outer wall of the knob 32, making it easier to rotate the knob 32.
[0026] The adjustment component also includes a slider 35, one side of which is rotatably mounted on one side of the vertical rod 34, and the outer wall of the slider 35 is slidably connected to one side of the guide plate 21. The slider 35 is T-shaped and is used for the movable connection between the vertical rod 34 and the guide plate 21. A groove adapted to the slider 35 is provided on one side of the guide plate 21.
[0027] The tops of the two electromagnetic plates 22 are respectively penetrated on both sides of the outer wall of the vertical rod 34; The vertical rod 34 is in sliding engagement with the electromagnetic plate 22.
[0028] Working principle: Before installing the iron removal device in the stainless steel pipe, turn the knob 32. The rotation of the knob 32 drives the lead screw 31 to rotate, causing the lead screw 31 to move up and down while rotating. The up and down movement of the lead screw 31 drives the horizontal plate 33 to move up and down. The up and down movement of the horizontal plate 33 drives the guide plate 21 to rotate through the vertical rod 34 until the guide plate 21 rotates to a suitable angle. In this way, the angle of the guide plate 21 can be easily adjusted to adapt to the flow characteristics of materials with different particle sizes and avoid material accumulation and blockage.
