Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to an improved iron removal device. Background Technology

[0002] In the production of fine chemical products such as aluminum pigments and high-end inks, iron filings are generated due to the friction between the ball mill and the grinding media. Raw materials may contain a small amount of iron filings as impurities, which can be carried into qualified products during the discharge process, causing them to be unqualified in downstream applications. Iron filings need to be removed by adsorption using an iron remover to avoid affecting the purity and color of the products.

[0003] Existing iron separators mostly use fixed magnetic rod arrays. The side of the magnetic rods facing the material is subjected to high concentrations of iron filings for a long time, which easily leads to saturation, while the utilization rate of the side facing the material is low, resulting in uneven utilization of overall magnetic energy. Fine iron filings in high-viscosity materials such as aluminum pigments tend to agglomerate, forming iron clumps. Traditional magnetic rods rely solely on static magnetic field adsorption, which is difficult to effectively disperse such agglomerates, causing some iron clumps to slide past the magnetic rod area, resulting in incomplete iron removal. Furthermore, cleaning the iron filings adsorbed on the surface of the magnetic rods usually relies on stopping the machine, opening the cover, manual scraping, or washing with water, which is time-consuming and causes production interruptions. Frequent opening of the cover can easily lead to wear of the seals and cause leakage risks.

[0004] To address these issues, an improved iron separator device is provided. Utility Model Content

[0005] The purpose of this invention is to provide an improved iron remover device that solves the problems of low utilization rate of magnetic rods, low efficiency in capturing agglomerated iron filings, and inconvenient maintenance in the prior art.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] An improved iron separator device includes:

[0008] Box;

[0009] The lid covers the top opening of the box body;

[0010] Multiple magnetic rods are arranged in multiple staggered rows inside the box along the material flow direction. The upper end of each magnetic rod is rotatably mounted on the box cover, and the lower end is suspended inside the box.

[0011] An adjustment frame is positioned across the upper end of the box cover and is connected to the upper end of each of the magnetic rods for synchronously driving multiple magnetic rods to rotate around their axis, thereby switching the material-facing side and the material-repelling side of the magnetic rods.

[0012] Also includes:

[0013] Multiple guide plates are fixedly installed on the downstream side of each magnetic rod. The guide plates have a V-shaped structure with their apex facing the central axis of the magnetic rod and their two wings extending obliquely backward. They are used to break up the iron filings agglomerate of the material flowing past the magnetic rod and guide the material to the next row of magnetic rods obliquely backward.

[0014] As a further optimization of this utility model, the two ends of the box are respectively provided with a feed pipe and a discharge pipe, and both the feed pipe and the discharge pipe are provided with valves.

[0015] As a further optimization of this utility model, the lid and the body are provided with multiple buckles evenly distributed along the contour, and the top of the lid is provided with two symmetrically distributed lifting lugs.

[0016] As a further optimization of this utility model, the upper end of the magnetic rod is fixedly provided with a rotating shaft for rotating connection with the box cover, and a gear is fixedly sleeved on the rotating shaft.

[0017] As a further optimization of this utility model, the adjustment frame includes two parallel end plates and a plurality of connecting rods fixed between the two end plates; each connecting rod has a rack that meshes with the gear at the position corresponding to the gear; the outer side of the end plate has a pull hole and the inner side has a locking block; the side of the box body has a locking hole that cooperates with the locking block.

[0018] As a further optimization of this utility model, the surface of the guide plate is provided with serrations distributed in a dot matrix pattern.

[0019] As a further optimization of this utility model, it also includes an adsorption component integrated on the guide plate, which is used to scrape off the iron filings attached to the surface of the magnetic rod during its rotation and adsorb and transport them to an external collection device.

[0020] As a further optimization of this utility model, the adsorption assembly includes multiple fixing plates fixed at the tips of corresponding guide plates. Each fixing plate is provided with a scraper that abuts against the magnetic rod. The fixing plates on both sides of the scraper are provided with multiple adsorption holes evenly distributed along the axial direction of the magnetic rod. The adsorption assembly also includes a collection tank located on the outside of the box, an adsorption pump located at the top of the collection tank, and an adsorption pipeline connecting the fixing plates and the adsorption pump.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. This utility model achieves periodic reversal of the magnetic rod's facing and backing sides by adjusting the rotating magnetic rod, so that all surfaces of the magnetic rod participate in the adsorption process evenly, avoiding premature saturation of a single surface, significantly balancing the magnetic field load, and effectively extending the overall continuous working time of the magnetic rod.

[0023] 2. This utility model adopts a multi-row staggered magnetic rod array, and a V-shaped guide plate is set behind each magnetic rod. The two work together to enhance the adsorption effect. The guide plate not only diverts and guides the flowing material to the frontal area of ​​the magnetic rod at the oblique rear, realizing the orderly transmission of the flow field, but its serrations can also shear and impact the residual iron filings, realizing secondary crushing and improving the adsorption efficiency of the subsequent magnetic rods. At the same time, it effectively solves the problem that high-viscosity materials are prone to forming flow dead corners and material accumulation behind the magnetic rods.

[0024] 3. This utility model integrates a scraping and suction adsorption component at the tip of the guide plate to form a distributed cleaning unit. During the rotation of the magnetic rod, the elastic scraper uses the rotation of the magnetic rod itself to mechanically peel off the iron filings attached to the surface. At the same time, the negative pressure adsorption system immediately sucks up the peeled material through the adsorption hole and transports it to the external collection tank. The entire cleaning process is completed in a closed state, avoiding the risk of wear and leakage of the seal due to frequent opening of the lid, and avoiding frequent production interruptions.

[0032] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0033] Example 1

[0034] To address the issues of low utilization rate of the magnetic rod 2, poor efficiency in capturing agglomerated iron filings, and inconvenient maintenance in existing technologies, please refer to [link to relevant documentation]. Figures 1-3 The present invention provides an improved iron separator device, comprising:

[0035] Box 1, with a feed pipe 101 and a discharge pipe 102 at each end, and a valve 103 on both feed pipe 101 and discharge pipe 102. Box 1 is a cuboid structure with a material channel inside and an opening at the top.

[0036] The cover 3 is fitted over the top opening of the box body 1. Multiple buckles 301 are evenly distributed along the contour between the cover 3 and the box body 1 to enable quick locking and unlocking of the cover 3. The top of the cover 3 is provided with two symmetrically distributed lifting lugs 302 for use with lifting equipment for disassembly and assembly operations. The buckles 301 can be stainless steel spring quick-release clamps or eccentric pressure buckles, with 4-8 buckles evenly distributed along the circumference of the cover 3 and the box body 1. The cover 3 can be locked and opened quickly without tools to improve maintenance efficiency.

[0037] Multiple magnetic rods 2 are arranged in multiple staggered rows inside the box 1 along the material flow direction. The upper end of each magnetic rod 2 is rotatably mounted on the box cover 3, which is used to periodically adjust its circumferential position during the working process, and the lower end is suspended inside the box 1.

[0038] The adjusting frame 4 is positioned across the upper end of the box cover 3 and is connected to the upper end of each magnetic rod 2 for synchronously driving multiple magnetic rods 2 to rotate around its axis, thereby switching the material-facing side and the material-receiving side of the magnetic rod 2.

[0039] like Figures 4-5 As shown, the upper end of the magnetic rod 2 is fixedly provided with a rotating shaft for rotating connection with the box cover 3, and a gear 201 is fixedly sleeved on the rotating shaft.

[0040] The adjustment frame 4 includes two parallel end plates 401 and a plurality of connecting rods 402 fixed between the two end plates 401; each connecting rod 402 has a rack 403 that meshes with the gear 201 at the corresponding position; the outer side of the end plate 401 has a pull hole 405 and the inner side has a locking block 404; the side of the housing 1 has a locking hole that cooperates with the locking block 404.

[0041] When the valve 103 on the feed pipe 101 is closed, the operator pushes the adjusting frame 4 horizontally through the pull hole 405. When the adjusting frame 4 moves, the rack 403 on it drives all the gears 201 that mesh with it to rotate synchronously. The gears 201 drive the magnetic rod 2 to rotate around the axis. When it is pushed to the set stroke, such as two and a half times, the locking block 404 is just embedded in the locking hole on the side wall of the box 1 to achieve mechanical limit and locking. At this time, the receiving side and the back side of the magnetic rod 2 are reversed. Pulling the adjusting frame 4 in the opposite direction can reset it or perform the next round of operation.

[0042] Also includes:

[0043] Multiple guide plates 5 are fixedly installed on the downstream side of each magnetic rod 2. The guide plates 5 have a V-shaped structure with an included angle of 60°-120°. The apex of the guide plate is set towards the central axis of the magnetic rod 2, and the two wings extend obliquely backward. They are used to break up the iron filings agglomerate of the material flowing through the magnetic rod 2 and guide the material to the next row of magnetic rods 2 obliquely backward. The surface of the guide plate 5 is provided with serrations 501 distributed in a dot matrix. The serrations 501 are composed of multiple conical protrusions or triangular cutting edges, which are used to enhance the shearing and crushing effect on the agglomerated iron filings in high viscosity materials.

[0044] High-viscosity materials containing iron impurities (such as aluminum pigment slurry) flow in from the feed pipe 101 at one end of the tank 1. At this time, the valves 103 on both the feed pipe 101 and the discharge pipe 102 are open to ensure continuous material flow. The high-viscosity material first impacts the receiving side of the first row of magnetic bars 2, and the iron filings are attracted by the strong magnetic field. After flowing past the magnetic bars 2, the material enters the area of ​​the V-shaped guide plate 5 behind them. The V-shaped structure divides the main flow into two streams, which are guided diagonally backward to the receiving side of the next row of magnetic bars 2. During this process, the serrations 501 of the guide plate 5 affect the residual iron filings. The remaining iron filings generate shearing and impact effects, achieving secondary fragmentation and improving the capture efficiency of the subsequent magnetic rods 2. After a certain number of cycles, the operator starts the adjustment frame 4, synchronously driving all magnetic rods 2 to rotate two and a half times, turning the original back material side into the front material side and the original front material side into the back material side. After the equipment has been running for a long time (such as several months or dozens of cleaning cycles), deep maintenance is performed. At this time, the inlet and outlet valves 103 are closed, the buckle 301 is opened, and the box cover 3 is lifted by the lifting lug 302, and the magnetic rods 2 are lifted accordingly for comprehensive cleaning.

[0045] Example 2

[0046] Based on Embodiment 1, in order to solve the problem that the magnetic rod 2 needs to be frequently removed for cleaning in the prior art, such as Figures 1-4 As shown, it also includes an adsorption component 6 integrated on the guide plate 5. The adsorption component 6 is used to scrape off the iron filings attached to the surface of the magnetic rod 2 during its rotation and adsorb and transport them to an external collection device.

[0047] The adsorption assembly 6 includes multiple fixing plates 601 fixed at the tips of corresponding guide plates 5. Each fixing plate 601 has a scraper 602 that abuts against the magnetic rod 2. The scraper 602 is made of polyurethane, nylon, or flexible rubber material and has good wear resistance, elasticity, and self-cleaning properties. Its cutting edge is wedge-shaped or arc-shaped and can slide closely against the surface of the magnetic rod 2 to effectively scrape off the adsorbed iron filings and adhering materials, while avoiding scratching the stainless steel sheath of the magnetic rod 2. The fixing plates 601 on both sides of the scraper 602 have multiple adsorption holes 603 evenly distributed along the axial direction of the magnetic rod 2. The adsorption assembly 6 also includes a collection tank 606 located on the outside of the housing 1, an adsorption pump 605 located on the top of the collection tank 606, and an adsorption pipeline 604 connecting the fixing plate 601 and the adsorption pump 605.

[0048] Close valve 103 on feed pipe 101, keep discharge pipe 102 open or briefly closed, start adsorption pump 605, the system forms a stable negative pressure zone at adsorption hole 603, push adjustment frame 4, drive all magnetic rods 2 to rotate slowly, scraper 602 scrapes off the attached iron filings, the scraped iron filings are immediately captured by the negative pressure airflow generated by adsorption hole 603, and transported to collection tank 606 for temporary storage through adsorption pipeline 604. After magnetic rod 2 rotates two and a half times, surface cleaning is completed, adsorption pump 605 is turned off. The scraping action of scraper 602 is completed by the rotation power of magnetic rod 2 itself, without the need for additional drive device, saving energy consumption.

[0049] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
