Description

Technical Field

[0001] This utility model relates to the field of material handling technology, specifically to an iron impurity filter. Background Technology

[0002] In modern industrial production, iron impurities in materials can severely impact subsequent processing and product quality. For example, in the food and pharmaceutical industries, iron impurities not only affect the taste and quality of products but may also endanger consumer health. In machining and chemical industries, iron impurities can accelerate equipment wear, lead to equipment failure, reduce production efficiency, and even cause safety accidents. Therefore, efficiently removing iron impurities from materials has become a crucial step in industrial production.

[0003] An existing iron impurity filtration device is described in Chinese patent application number CN202323210714.9. This utility model includes a main body shell, an internal electromagnetic source magnet mounted on the main body shell, a three-way structure at the bottom of the main body shell, and an impurity recovery cylinder. The external side of the internal electromagnetic source magnet has a protruding iron ring, and the internal side has a wound coil. When energized, the wound coil adsorbs iron impurities through the iron ring. A material distribution plate is movably arranged within the three-way structure, along with a cylinder that drives the material distribution plate. Existing iron impurity filtration devices typically employ sieving or static adsorption methods. Sieving methods do not completely filter iron impurities, while existing adsorption methods require regular manual cleaning, making operation cumbersome.

[0004] Therefore, we propose an iron impurity filter to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide an iron impurity filter to solve the problems of incomplete filtration or cumbersome operation of existing iron impurity filtration devices mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an iron impurity filter, comprising a filter tube and a feed hopper fixed at the upper end: The upper end of the filter tube is connected to a rotating shaft, the outer wall of the rotating shaft is connected to a limiting material deflector, the side of the filter tube is connected to a power motor, the limiting material deflector is provided with guide plates on both sides, the lower end of the guide plate is provided with a cleaning roller, and the side of the cleaning roller is provided with a feeding guide tube, which is connected to the inside of the filter tube. The impurity removal roller has a support rod running through it, and a strong magnetic block is connected to the outer wall of the support rod. A collection box is provided at the bottom of the filter tube.

[0007] Preferably, the rotating shaft is rotatably connected to the inner wall of the filter tube, and the rear end of the rotating shaft is connected to the shaft end of the power motor. The outer wall of the rotating shaft is fixed to the material limiting plate, and the material limiting plate is distributed in a ring array with the rotating shaft as the center.

[0008] Using the above technical solution, the power motor can provide rotational power to the rotating shaft. When the rotating shaft rotates, it drives multiple sets of limiting plates to rotate as well. When the limiting plates rotate, uniform and quantitative feeding can be achieved.

[0009] Preferably, the guide plates are symmetrically connected to the inner walls of both sides of the filter tube, and the middle part of the guide plates is designed in an arc shape, and the inner wall shape of the guide plates is in contact with the material limiting plate. The lower ends of the two sets of guide plates are designed to be inclined towards the middle.

[0010] By adopting the above technical solution, two sets of guide plates ensure that no material is discharged from the sides when the material limiting plate rotates to discharge material. At the same time, the lower ends of the two sets of guide plates are inclined towards the middle to ensure that the material can be discharged in the middle of the filter tube.

[0011] Preferably, the outer wall of the impurity removal roller is provided with grooves in an annular array, and the front end of the impurity removal roller is fixedly connected to the drive shaft. The rear end of the support rod passes through the outside of the impurity removal roller and is fixed to the inner wall of the filter tube. The strong magnetic block is fixed to the left side and the top end of the support rod. The strong magnetic block is designed in a fan shape and is in close contact with the inner wall of the impurity removal roller. The impurity removal roller is provided with feeding guide plates on both sides. The upper end of the feeding guide plate on the right side is engaged with the guide plate. The inner wall shape of the feeding guide plate is adapted to the shape of the impurity removal roller.

[0012] Using the above technical solution, the impurity removal roller can be driven to rotate synchronously through the transmission shaft. The grooves opened on the outer wall of the impurity removal roller facilitate the collection of materials. In conjunction with the strong magnetic blocks set inside the impurity removal roller, impurities such as iron filings mixed in the materials can be adsorbed. When the materials in the groove move to the area where no strong magnetic blocks are set, the iron filings can be separated from the impurity removal roller.

[0013] Preferably, the front end of the drive shaft passes through the outside of the filter tube and is connected to a second pulley, the front end of the rotating shaft passes through the outside of the filter tube and is connected to a first pulley, and a drive belt is connected between the first pulley and the second pulley.

[0014] Using the above technical solution, when the shaft rotates, it can drive the first pulley to rotate. The first pulley drives the second transmission belt, the transmission shaft and the impurity removal roller to rotate synchronously using the transmission belt. The transmission belt has a groove inside, and the outer walls of the first and second pulleys are provided with protrusions that match the inner wall of the transmission belt to maintain stable transmission and prevent slippage.

[0015] Preferably, a positioning plate is connected to the inner wall of the feeding guide plate on the right side, and a cleaning brush is fixed on the inner side of the positioning plate, the cleaning brush being in contact with the outer wall of the impurity removal roller.

[0016] Using the above technical solution, the cleaning brush can be fixed to the inner wall of the feeding guide plate by the positioning plate. During the impurity removal roller process, the cleaning brush can clean the iron filings and powder attached to the outer wall of the impurity removal roller.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the iron impurity filter; 1. The quantitative feeding structure can feed materials at a uniform speed, and with the addition of a roller structure with strong magnetic adsorption, it can adsorb iron filings mixed in with the material during rotation and achieve autonomous feeding. This enables continuous impurity removal and filtration, improving the ease of operation and the efficiency of handling iron impurities. 2. Through the rotating iron impurity filtering structure, the iron filings and impurities falling into the outer wall of the impurity removal roller can be adsorbed by the strong magnetic structure. When the adsorbed impurities are rotated to the position where the strong magnet is not installed, they can be detached by themselves, thereby realizing autonomous impurity removal and material discharge, and improving the convenience of operation.

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.

[0021] Example 1, please refer to Figure 1-4This utility model provides a technical solution: an iron impurity filter, including a filter tube 1 and a feed hopper 2 fixed at the upper end. The upper end of the filter tube 1 is connected to a rotating shaft 3, and a limiting baffle 4 is connected to the outer wall of the rotating shaft 3. A power motor 7 is connected to the side of the filter tube 1, and guide plates 5 are arranged on both sides of the limiting baffle 4. The rotating shaft 3 is rotatably connected to the inner wall of the filter tube 1, and the rear end of the rotating shaft 3 is connected to the shaft end of the power motor 7. The outer wall of the rotating shaft 3 is fixed to the limiting baffle 4, and the limiting baffle 4 is arranged in a ring array around the rotating shaft 3. The guide plates 5 are symmetrically connected to the inner walls of both sides of the filter tube 1, and the middle part of the guide plates 5 is arc-shaped. The inner wall shape of the guide plates 5 is in contact with the limiting baffle 4, and the lower ends of the two sets of guide plates 5 are inclined towards the middle. When using the filter, the material is poured into the hopper 2, and then fed into the filter tube 1 through the hopper 2. The power motor 7 drives the rotating shaft 3 and multiple sets of limiting baffles 4 to rotate synchronously, allowing for quantitative feeding of the material. The guide plate 5 is matched to the rotation trajectory of the limiting baffles 4, ensuring no leakage of material between the two sets of limiting baffles 4 during rotation, thus ensuring uniform and quantitative feeding. Simultaneously, the lower ends of the two guide plates 5 are tilted towards the center, ensuring that the material falls into the middle of the filter tube 1.

[0022] A removal roller 8 is provided at the lower end of the guide plate 5, and a feeding guide 6 is provided on the side of the removal roller 8, which is connected to the inside of the filter tube 1. The outer wall of the removal roller 8 has grooves arranged in an annular array, and the front end of the removal roller 8 is fixedly connected to the drive shaft 9. The front end of the drive shaft 9 is connected to the second pulley 15, and the front end of the rotating shaft 3 passes through the outside of the filter tube 1 and is connected to the first pulley 14. A drive belt 16 is connected between the first pulley 14 and the second pulley 15. During the rotation of the rotating shaft 3, the first pulley 14 can drive the second pulley 15 and the drive shaft 9 to rotate synchronously by the drive belt 16, and the removal roller 8 is driven to rotate synchronously by the drive shaft 9. The removal roller 8 is located in the middle of the two sets of guide plates 5. When the material is discharged in the middle of the two sets of guide plates 5, it can fall into the groove inside the outer side of the removal roller 8.

[0023] A support rod 11 runs through the inside of the impurity removal roller 8, and a strong magnetic block 12 is connected to the outer wall of the support rod 11. A collection box 13 is provided at the bottom of the filter tube 1. The rear end of the support rod 11 runs through the outside of the impurity removal roller 8 and is fixed to the inner wall of the filter tube 1. The strong magnetic block 12 is fixed to the left and upper ends of the support rod 11. The strong magnetic block 12 has a fan-shaped design and is in close contact with the inner wall of the impurity removal roller 8. Feeding guide plates 10 are provided on both sides of the impurity removal roller 8. The upper end of the right feeding guide plate 10 is engaged with the guide plate 5. The inner wall shape of the feeding guide plate 10 is adapted to the shape of the impurity removal roller 8. The front end of the drive shaft 9 runs through the outside of the filter tube 1. When the material falls into the groove outside the impurity removal roller 8, the strong magnetic block 12 fixed to the outer wall of the support rod 11 can adsorb the iron filings and impurities inside the groove. When the strong magnetic block 12 rotates to the left, the remaining material is discharged into the feeding guide 6 due to gravity. As the impurity removal roller 8 continues to rotate, the support rod 11 has a strong magnetic block 12 at the bottom. The iron filings adsorbed by the material inside the groove can be separated from the impurity removal roller 8 and fall into the collection box 13. The collection box 13 is slidably connected to the bottom of the filter tube 1, which can facilitate the quick processing of the collected iron filings and impurities.

[0024] Example 2, please refer to Figure 5 This utility model provides a technical solution. The difference between this embodiment and Embodiment 1 is that a cleaning structure is provided, which can clean the outer wall of the impurity removal roller 8, thereby improving the thoroughness of iron filings and impurities separation. A positioning plate 17 is connected to the inner wall of the right-side feeding guide plate 10, and a cleaning brush 18 is fixed inside the positioning plate 17. The cleaning brush 18 contacts the outer wall of the impurity removal roller 8. The positioning plate 17 can fix the cleaning brush 18 to the inner wall of the feeding guide plate 10. When the iron filings and impurities adsorbed in the groove move to the lower end of the impurity removal roller 8, they will be separated and discharged, but some residue may remain. The design of the cleaning brush 18 can further clean the iron filings and impurities residue, improving the iron filings and impurities cleaning effect.
