Description
Technical Field
[0001] This utility model relates to the field of calcium carbonate processing technology, and in particular to a strong electromagnetic iron removal device. Background Technology
[0002] Calcium carbonate, as a key industrial raw material, is widely used in many industries such as plastics, coatings, and papermaking. In its powder production process, due to equipment wear and other factors, fine metal particles, such as iron filings, often mix into the product. The presence of these impurities will severely reduce the purity of the calcium carbonate product, thus adversely affecting its performance in various applications. On the other hand, when calcium carbonate powder containing these impurities enters the subsequent processing flow, the fine metal particles will cause damage to mechanical equipment, such as accelerated wear of key components, jamming, or even malfunctions. It may also pose safety hazards. Therefore, a strong electromagnetic iron removal device is needed to remove metal impurities during the calcium carbonate powder production process, ensuring product quality and production safety, and ensuring the stable operation of the entire industrial chain.
[0003] A search revealed Chinese patent publication number CN220919874U, which discloses a filtration device for producing calcium carbonate. The device includes a main body with a first and second filter screen inside. The outer sides of the first and second filter screens are fixedly connected to the inner wall of the main body via silicone gaskets. A discharge cylinder is inserted through the middle of the surfaces of the first and second filter screens. A sealing disc is slidably inserted inside the discharge cylinder. A pressure rod is inserted through the surface of the sealing disc, and a screw is attached to the top of the pressure rod. One end of the screw spirally passes through the top surface of the main body and is connected to a crank handle. A first conveying pipe is obliquely inserted through the surface of the discharge cylinder. This invention, through the coordinated use of silicone gaskets, a discharge cylinder, a sealing disc, a first conveying pipe, a second conveying pipe, a flexible hose, a pressure rod, and a screw, facilitates the discharge of impurities from each filter screen after calcium carbonate filtration. While this method is simple to operate, in actual use, fine metal particles cannot be effectively filtered out, which can affect subsequent production and product quality. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a strong electromagnetic iron removal device, which aims to improve the problem that fine metal particles cannot be effectively filtered out in the filter screen in the existing technology.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a strong electromagnetic iron removal device, comprising a feeding hopper, wherein multiple fixed columns are fixedly connected to the top of the outer wall of the feeding hopper, a flange circle is fixedly connected to the bottom of the outer wall of the feeding hopper, a guide pipe is connected to the bottom of the flange circle, a servo motor is fixedly connected to the right side of the outer wall of the guide pipe, the output end of the servo motor passes through the guide pipe and is fixedly connected to an auger, processing boxes are connected to the left and right sides of the bottom of the outer wall of the guide pipe, a discharge pipe is connected to the bottom of the outer wall of the processing box, a limit block is provided at the bottom of the right side of the discharge pipe, a hollow plate is slidably connected to the inner wall of the processing box, multiple strong magnetic adsorption plates are fixedly connected to the inner wall of the hollow plate, and a rotation adjustment mechanism is provided on the inner wall of the hollow plate.
[0006] The above technical solution involves fixing the feeding hopper to the roof of the building using fixed columns. Calcium carbonate raw materials enter the feeding hopper through pipes on the upper floor. When large packaging bags are needed, a servo motor is activated to rotate the auger, causing the calcium carbonate entering the guide pipe from the feeding hopper to move to the left and fall into the large packaging bag through the processing box and discharge pipe. When small packaging bags are needed, the servo motor is activated in reverse, causing the calcium carbonate entering the guide pipe to move to the right and fall into the small packaging bag through the processing box and discharge pipe. Upon entering the processing box, a strong magnetic adsorption plate is activated to adsorb fine metal objects in the calcium carbonate, thus filtering them out and preventing them from affecting the final quality of the calcium carbonate and damaging subsequent equipment.
[0007] As a further description of the above technical solution:
[0008] The rotation adjustment mechanism includes a moving bar slidably connected to the inner wall of the hollow plate. The front side of the moving bar passes through the hollow plate and is fixedly connected to a pull ring. The outer wall of the moving bar is provided with multiple grooved plates. The front right side of the grooved plate has a notch. The outer wall of the moving bar is rotatably connected to the multiple notches. The bottom left and right sides of the grooved plates are rotatably connected to the inner wall of the hollow plate. The inner wall of the hollow plate is provided with a receiving plate. The left and right sides of the receiving plate are fixedly connected to slide rails. The two slide rails are slidably connected to the left and right sides of the inner wall of the hollow plate, respectively.
[0009] The above technical solution works as follows: When calcium carbonate is filtered above the strong magnetic adsorption plate, pulling the pull ring moves the moving strip, which in turn rotates the groove plate, changing the direction of calcium carbonate's fall. This allows the calcium carbonate to remain in the strong magnetic adsorption plate for a longer time, further improving the efficiency of adsorbing fine metal objects. After a certain period of use, the servo motor stops pushing calcium carbonate into the processing box, and the receiving plate is pushed in so that it is directly below the strong magnetic adsorption plate. Then, the strong magnetic adsorption plate is closed, and the fine metal objects adsorbed on the surface lose their magnetic attraction and fall into the receiving plate. The receiving plate can then be pulled out for cleaning, thus increasing the reuse time.
[0010] As a further description of the above technical solution:
[0011] A heating ring is fixedly connected to the inner wall of the feeding hopper, and an electronic scale is fixedly connected to the bottom of the inner wall of the limiting block.
[0012] The above technical solution allows for the heating and drying of calcium carbonate entering the feeding hopper via a heating ring to remove moisture, and the weighing of small packages via an electronic scale.
[0013] As a further description of the above technical solution:
[0014] An observation window is provided on the front side of the outer wall of the feeding hopper, and an outer frame is fixedly connected to the outer wall of the observation window.
[0015] The above technical solution allows for easy observation of the material hopper through the observation window, while the outer frame enhances the structural strength of the observation window.
[0016] As a further description of the above technical solution:
[0017] A cooling ring is fixedly connected to the top of the outer wall of the processing tank. A cooling water pipe is connected to the left side of the outer wall of the cooling ring, and a hot water drain pipe is connected to the right side of the outer wall of the cooling ring.
[0018] The above technical solution allows for the cooling of calcium carbonate entering the processing chamber via a cooling ring, preventing the loss of magnetism above the strong magnetic adsorption plate due to high temperatures. Cold water enters the cooling ring from the cooling water pipe, absorbs heat, and is then discharged from the hot water drain pipe.
[0019] As a further description of the above technical solution:
[0020] A handle is fixedly connected to the front side of the receiving plate, and a column is fixedly connected to the top right side of the outer wall of the limiting block.
[0021] The above technical solution allows for easy removal of the receiving plate via a handle, and the display control screen can be supported by a column.
[0022] As a further description of the above technical solution:
[0023] The top of the column is rotatably connected to a display control screen, which is electrically connected to a servo motor, a strong magnetic adsorption plate, a heating ring, and an electronic scale.
[0024] The above technical solution allows for the separate control of the starting and operating power of the servo motor, strong magnetic adsorption plate, heating ring, and electronic scale via a display control panel.
[0025] As a further description of the above technical solution:
[0026] The top of the inner wall of the limiting block is fixedly connected with multiple hooks, and the two hooks on the left and right sides are symmetrically fixed to the inner wall of the limiting block.
[0027] The above technical solution allows for the use of hooks to help open packaging bags when packaging small packages.
[0028] This utility model has the following beneficial effects:
[0029] 1. In this utility model, the feeding hopper is installed on the roof by a fixed column. The calcium carbonate raw material is transported to the feeding hopper through a pipeline. When packaging large items, the servo motor is started to rotate the auger and the calcium carbonate moves to the left to the large packaging bag. When packaging small items, the reverse operation is performed to move the calcium carbonate to the right to the small packaging bag. In front of the processing box, a strong magnetic adsorption plate is activated to adsorb metal impurities, thereby ensuring the quality of calcium carbonate and protecting the equipment.
[0030] 2. In this utility model, by pulling the pull ring to move the moving strip, the groove plate is rotated, changing the falling direction of calcium carbonate, extending its residence time in the strong magnetic adsorption plate, and improving the efficiency of adsorbing metal objects. After a period of use, the servo motor stops pushing calcium carbonate, pushes the receiving plate to the bottom of the strong magnetic adsorption plate, and closes the adsorption plate. The adsorbed metal objects fall onto the receiving plate due to the loss of magnetism. The receiving plate can be pulled out to complete the cleaning, thereby extending the repeated use time of the equipment. Attached Figure Description

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.
[0040] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a strong electromagnetic iron removal device, comprising a feeding hopper 1. Multiple fixed columns 3 are fixedly connected to the top of the outer wall of the feeding hopper 1, fixing the feeding hopper 1 to the roof of a building. A flange circle 4 is fixedly connected to the bottom of the outer wall of the feeding hopper 1, and a guide pipe 5 is connected to the bottom of the flange circle 4. A servo motor 6 is fixedly connected to the right side of the outer wall of the guide pipe 5. The output end of the servo motor 6 passes through the guide pipe 5 and is fixedly connected to a auger 7. Processing boxes 8 are connected to the left and right sides of the bottom of the outer wall of the guide pipe 5, and a discharge pipe 9 is connected to the bottom of the outer wall of the processing box 8. The device is activated upon startup. Servo motor 6 drives auger 7 to rotate, causing calcium carbonate entering the guide pipe 5 from the feeding bin 1 to move to the left and fall into the large packaging bag through the processing box 8 and discharge pipe 9. Conversely, it will enter the small packaging bag. Limit block 10 is set at the bottom of the discharge pipe 9 on the right. Hollow plate 11 is slidably connected to the inner wall of the processing box 8. Multiple strong magnetic adsorption plates 12 are fixedly connected to the inner wall of the hollow plate 11. When the strong magnetic adsorption plates 12 are activated, the fine metal objects in the calcium carbonate can be adsorbed, thereby filtering them out of the calcium carbonate. Rotation adjustment mechanism 2 is set on the inner wall of the hollow plate 11.
[0041] Specifically, the fixed column 3 fixes the feeding hopper 1 to the top of the building. Calcium carbonate raw material enters the feeding hopper 1 through the upstairs pipe. When it needs to be bagged into large packaging bags, the servo motor 6 is started, driving the auger 7 to rotate, causing the calcium carbonate entering the guide pipe 5 from the feeding hopper 1 to move to the left and fall into the large packaging bag through the processing box 8 and the discharge pipe 9. When it needs to be bagged into small packaging bags, the servo motor 6 is started in reverse, causing the calcium carbonate entering the guide pipe 5 to move to the right and fall into the small packaging bag through the processing box 8 and the discharge pipe 9. When entering the processing box 8, the strong magnetic adsorption plate 12 is activated to adsorb the fine metal objects in the calcium carbonate, thereby filtering them out of the calcium carbonate and avoiding affecting the quality of the final calcium carbonate and damage to subsequent equipment.
[0042] Reference Figure 1 , Figure 5 and Figure 6The rotation adjustment mechanism 2 includes a movable bar 202, which is slidably connected to the inner wall of the hollow plate 11. The front side of the movable bar 202 passes through the hollow plate 11 and is fixedly connected to a pull ring 201. The outer wall of the movable bar 202 is provided with multiple grooved plates 203. The front right side of the grooved plate 203 has a notch 204. The outer wall of the movable bar 202 is rotatably connected to the multiple notches 204 respectively. The bottom left and right sides of the grooved plate 203 are rotatably connected to the inner wall of the hollow plate 11. Pulling the pull ring 201 can move the moving bar 202, which will pull the groove plate 203 to rotate, thereby changing the direction of calcium carbonate falling. The inner wall of the hollow plate 11 is provided with a receiving plate 205, which can collect and clean the adsorbed small metal objects. The left and right sides of the receiving plate 205 are fixedly connected with slide rails 206, which facilitates the movement of the receiving plate 205. The two slide rails 206 are slidably connected to the left and right sides of the inner wall of the hollow plate 11 respectively.
[0043] Specifically, when calcium carbonate is filtered above the strong magnetic adsorption plate 12, pulling the pull ring 201 moves the moving bar 202, which in turn rotates the groove plate 203, changing the direction of calcium carbonate's fall. This allows the calcium carbonate to remain in the strong magnetic adsorption plate 12 for a longer time, further improving the efficiency of adsorbing fine metal objects. After a certain period of use, the servo motor 6 stops pushing calcium carbonate into the processing box 8, and the receiving plate 205 is pushed in so that it is directly below the strong magnetic adsorption plate 12. Then, the strong magnetic adsorption plate 12 is closed, and the fine metal objects adsorbed on the surface lose their magnetic attraction and fall into the receiving plate 205. The receiving plate 205 can then be pulled out for cleaning, thus increasing its reusability.
[0044] Reference Figure 1 , Figure 2 and Figure 3A heating ring 13 is fixedly connected to the inner wall of the feeding hopper 1. The heating ring 13 can heat and dry the calcium carbonate entering the feeding hopper 1 to remove moisture. An electronic scale 23 is fixedly connected to the bottom of the inner wall of the limiting block 10. The electronic scale 23 can weigh small packages. An observation window 14 is opened on the front side of the outer wall of the feeding hopper 1. An outer frame 15 is fixedly connected to the outer wall of the observation window 14. The observation window 14 can facilitate the observation of the situation in the feeding hopper 1. The outer frame 15 can improve the structural strength of the observation window 14. A cooling ring 16 is fixedly connected to the top of the outer wall of the processing box 8. A cooling water pipe 17 is connected to the left side of the outer wall of the cooling ring 16, and a hot water drain pipe 18 is connected to the right side of the outer wall of the cooling ring 16. The cooling ring 16 can cool the calcium carbonate entering the processing box 8 to prevent the magnetism above the strong magnetic adsorption plate 12 from disappearing due to high temperature. Cold water enters from the cooling water pipe 17. Cooling ring 16 absorbs heat and discharges it through hot water pipe 18; a handle 19 is fixedly connected to the front side of receiving plate 205, and a column 20 is fixedly connected to the top right side of the outer wall of limiting block 10. The handle 19 facilitates the removal of receiving plate 205, and the column 20 supports display control screen 21; the top of column 20 is rotatably connected to display control screen 21, which is electrically connected to servo motor 6, strong magnetic adsorption plate 12, heating ring 13 and electronic scale 23 respectively. Display control screen 21 can control the starting and running power of servo motor 6, strong magnetic adsorption plate 12, heating ring 13 and electronic scale 23 respectively; multiple hooks 22 are fixedly connected to the top of inner wall of limiting block 10, and two hooks 22 on the left and right sides are symmetrically fixed to the inner wall of limiting block 10. The hooks 22 can help open the packaging bag when packaging small packages;
[0045] Specifically, the heating ring 13 heats and dries the calcium carbonate entering the feeding hopper 1 to remove moisture. The electronic scale 23 weighs the small packages. The observation window 14 allows for easy observation of the situation in the feeding hopper 1. The outer frame 15 enhances the structural strength of the observation window 14. The cooling ring 16 cools the calcium carbonate entering the processing box 8 to prevent the loss of magnetism above the strong magnetic adsorption plate 12 due to high temperature. Cold water enters the cooling ring 16 from the cooling water pipe 17, absorbs heat, and is discharged from the hot water drain pipe 18. The handle 19 allows for easy removal of the receiving plate 205. The column 20 supports the display control screen 21, which controls the starting and running power of the servo motor 6, the strong magnetic adsorption plate 12, the heating ring 13, and the electronic scale 23. The hook 22 helps to open the packaging bag when packaging the small packages.
[0046] Working Principle: First, the fixed column 3 is responsible for installing the feeding hopper 1 on the roof of the building. Calcium carbonate raw material is guided into the feeding hopper 1 through pipes on the upper floor. When large packaging bags are needed, the servo motor 6 is activated, driving the auger 7 to rotate, causing the calcium carbonate entering the guide pipe 5 from the feeding hopper 1 to move to the left, and finally fall into the large packaging bag through the processing box 8 and the discharge pipe 9. If small packaging bags are needed, the servo motor 6 is simply activated in reverse, causing the calcium carbonate in the guide pipe 5 to move to the right, and then fall into the small packaging bag through the processing box 8 and the discharge pipe 9. During the process of entering the processing box 8, the strong magnetic adsorption plate 12 is activated, which adsorbs fine metal impurities in the calcium carbonate, achieving filtration from the calcium carbonate, thereby ensuring the quality of the final calcium carbonate product and avoiding potential damage to subsequent equipment. The rotation adjustment... Mechanism 2: During the filtration of calcium carbonate above the strong magnetic adsorption plate 12, pulling the pull ring 201 can move the moving bar 202, thereby causing the groove plate 203 to rotate. This adjusts the falling path of the calcium carbonate, prolonging its residence time on the strong magnetic adsorption plate 12 and improving the adsorption efficiency of fine metal objects. After the equipment has been running for a period of time, the servo motor 6 will stop pushing calcium carbonate into the processing box 8. At this time, the receiving plate 205 is pushed into the position directly below the strong magnetic adsorption plate 12, and the magnetic function of the strong magnetic adsorption plate 12 is turned off. Subsequently, the fine metal objects adsorbed on the surface of the strong magnetic adsorption plate 12 will fall into the receiving plate 205 due to the loss of magnetic attraction. Finally, the receiving plate 205 is pulled out and cleaned, thus completing the collection and processing of fine metal objects and extending the continuous use time of the equipment.
