Description

Technical Field

[0001] This invention relates to the field of soft magnetic ferrite technology, and in particular to a magnetic sludge recycling device. Background Technology

[0002] Soft magnetic ferrites are ferrimagnetic oxides with Fe2O3 as the main component, produced using powder metallurgy. In the traditional production process of soft magnetic ferrite cores, both the green blank and the finished product typically require grinding to remove burrs from the core.

[0003] When polishing traditional soft ferrite cores, a large amount of sludge is usually generated. Since sludge is a major raw material in the core production process, it is necessary to recycle and reuse the sludge to reduce resource waste.

[0004] A Chinese invention patent with publication number "CN111531468B" and patent name "A Magnetic Grinding Sludge Recycling Device" discloses a structure that uses a permanent magnet chuck in conjunction with a synchronous belt to adsorb magnetic grinding sludge from wastewater. The sludge is then scraped off by a scraper. However, with this method, the scraper has limited efficiency during discharge and cannot completely remove the magnetic grinding sludge from the permanent magnet chuck. As a result, some grinding sludge remains on the permanent magnet chuck after it has been scraped off. When the permanent magnet chuck adsorbs the sludge again, it can only adsorb a small amount of grinding sludge, thus reducing the overall recycling efficiency. To solve this problem, a new magnetic grinding sludge recycling device is needed. Summary of the Invention

[0005] The purpose of this invention is to provide a magnetic sludge recycling device with higher recycling efficiency.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0007] A magnetic sludge recycling device includes a wastewater tank and a frame. A roller is horizontally rotatable inside the wastewater tank. The roller has several openings on its surface, and a closing plate is hinged to each opening. An electromagnet is mounted on the outside of each closing plate. Support plates and conductive rings are mounted on both sides of the roller. The support plates and conductive rings are fixedly connected to the frame. The main body of the support plate is circular, and the conductive rings are located on the outside of the support plates. An adjusting rod is mounted on each closing plate, connected to the electromagnet, and extends to the middle of the conductive rings and support plates. One end is attached to the support rod, and the other end is attached to the conductive ring. One of the conductive rings is connected to the positive terminal of the power supply, and the other conductive ring is connected to the negative terminal of the power supply. An adjustment notch is provided above the support plate. When the adjustment rod is located at the adjustment notch, the closing plate rotates inward towards the inside of the drum, and the adjustment rod disengages from the conductive ring. A collecting pipe is provided inside the drum, and an opening is provided at the upper end of the collecting pipe. When the closing plate opens downward, it connects with the opening on the collecting pipe. A conveying mechanism for transporting the grinding mud is provided inside the collecting pipe. A drive mechanism for driving the drum to rotate is provided on the frame.

[0008] As a further feature of the present invention, a fixing plate is provided on both sides of the roller, the fixing plate surrounds both sides of the roller, and a moving groove is provided on each adjusting rod of the fixing plate. The adjusting rod is slidably disposed in the moving groove, and the shape and length of the moving groove are matched with the travel of the adjusting rod. When the adjusting rod is at the top of the moving groove, the closing plate closes the roller, and when the adjusting rod is at the bottom of the moving groove, the closing plate rotates downward to open the roller.

[0009] As a further feature of the present invention, the collection pipe is located at the axis of the drum, the collection pipe extends outward through both sides of the drum to the outside of the sewage tank, the collection pipe is fixedly connected to the sewage tank, the drum is rotatably connected to the collection pipe, and the opening on the collection pipe is located inside the drum.

[0010] As a further feature of the present invention, a material collection frame is provided above the collection pipe. The material collection frame is trumpet-shaped, and the smaller end of the material collection frame is fixedly connected to the opening of the collection pipe. When the closing plate is rotated downward to open, the larger end of the material collection frame faces the side of the closing plate with the opening.

[0011] As a further feature of the present invention, the conveying mechanism includes a main shaft coaxially disposed in a collection tube, blades being spirally connected to the main shaft, a motor being connected to one side of the main shaft, and the side of the collection tube connected to the motor being open.

[0012] As a further feature of the present invention, the driving mechanism includes sleeves located on both sides of the drum, the sleeves being rotatably connected to the collecting pipe, and a second motor being mounted on the frame, the second motor being connected to the sleeves via a gear set.

[0013] The beneficial effects of this invention are:

[0014] This invention uses the rotation of a drum to drive the rotation of an electromagnet. When the electromagnet rotates into the sewage tank, it attracts the magnetic sludge there. As the drum continues to rotate, when it reaches the top of the drum, the closing plate opens, and the electromagnet loses power and magnetism. The adhered magnetic sludge falls into the collection pipe inside the drum under the action of gravity, and is then transported by a conveying mechanism to complete the collection of the magnetic sludge.

[0026] Example

[0027] A magnetic sludge recycling device includes a wastewater tank 1 and a frame. A roller 2 is horizontally rotatable inside the wastewater tank 1. Several openings are formed on the surface of the roller 2, and a closing plate 3 is hinged to each opening. An electromagnet is mounted on the outside of the closing plate 3. Support plates 4 and conductive rings 5 ​​are mounted on both sides of the roller 2. The support plates 4 and conductive rings 5 ​​are fixedly connected to the frame. The main body of the support plate 4 is circular, and the conductive rings 5 ​​are located on the outside of the support plate 4. An adjusting rod 6 is mounted on the closing plate 3, connected to the electromagnet, and extends to the middle of the conductive rings 5 ​​and the support plate 4. One end of the adjusting rod 6 is connected to... The support rod is attached to the other end and the conductive ring 5 is attached to the other end. One conductive ring 5 is connected to the positive terminal of the power supply and the other conductive ring 5 is connected to the negative terminal of the power supply. An adjustment notch 41 is provided above the support plate 4. When the adjustment rod 6 is located at the adjustment notch 41, the closing plate 3 rotates inward to the roller 2 and the adjustment rod 6 disengages from the conductive ring 5. A collection pipe 7 is provided inside the roller 2. An opening is provided at the upper end of the collection pipe 7. When the closing plate 3 opens downward, it connects with the opening on the collection pipe 7. A conveying mechanism 8 is provided inside the collection pipe 7 to transport the grinding mud out. A drive mechanism 9 is provided on the frame to drive the roller 2 to rotate.

[0028] Wastewater filled with magnetic abrasive is guided into wastewater tank 1. The depth of the wastewater should not completely submerge roller 2; ideally, it should only submerge half of roller 2. Then, roller 2 is driven to rotate via drive mechanism 9. As roller 2 rotates, it drives the closing plate 3 and the electromagnet to rotate. When the adjusting rod 6 has not rotated to the adjusting notch 41, it is in close contact with the conductive ring 5, thus supplying power to the electromagnet. The electromagnet is magnetic. When the closing plate 3 and the electromagnet rotate below roller 2 and are submerged in the wastewater, the electromagnet will attract the magnetic abrasive in the wastewater. The electromagnet slowly rotates to a higher position along with roller 2. When the adjusting rod rotates along with it… When the roller 2 rotates to the adjustment notch 41 on the high support rod, the adjustment rod moves downward under the action of gravity, thereby causing the closing plate 3 and the electromagnet to move downward. At this time, the adjustment rod disengages from the conductive ring 5, causing the electromagnet to lose power and thus lose its magnetism. The magnetic sludge previously adsorbed by the electromagnet falls downward into the collection pipe 7 under the action of gravity, and is then transported out of the collection pipe 7 by the conveying mechanism 8. As the roller 2 continues to rotate, the adjustment rod 6 moves out of the adjustment notch 41 and contacts the conductive ring 5 again, causing the electromagnet to be re-energized and regain its magnetism. The roller 2 is then immersed in the wastewater again to adsorb the magnetic sludge.

[0029] Furthermore, fixing plates 21 are provided on both sides of the roller 2, surrounding both sides of the roller 2. Each adjusting rod 6 is provided with a moving groove 22 on the fixing plate 21. The adjusting rod 6 is slidably disposed in the moving groove 22. The shape and length of the moving groove 22 match the travel of the adjusting rod 6. When the adjusting rod 6 is at the top of the moving groove 22, the closing plate 3 closes the roller 2; when the adjusting rod 6 is at the bottom of the moving groove 22, the closing plate 3 rotates downwards to open the roller 2. By providing the moving groove 22, the movement of the adjusting rod 6 can be better guided.

[0030] Furthermore, the collection pipe 7 is located at the axis of the roller 2. The collection pipe 7 extends outward through both sides of the roller 2 to the outside of the sewage tank 1. The collection pipe 7 is fixedly connected to the sewage tank 1, and the roller 2 is rotatably connected to the collection pipe 7. The opening on the collection pipe 7 is located inside the roller 2.

[0031] Furthermore, a collection frame 10 is provided above the collection pipe 7. The collection frame 10 is trumpet-shaped. The smaller end of the collection frame 10 is fixedly connected to the opening of the collection pipe 7. When the closing plate 3 is rotated downward to open, the larger end of the collection frame 10 faces the side of the closing plate 3 with the opening.

[0032] Furthermore, the conveying mechanism 8 includes a main shaft 81 coaxially arranged in the collection pipe 7, with blades 82 spirally connected to the main shaft 81, and a motor 83 connected to one side of the main shaft 81. The side of the collection pipe 7 connected to the motor is set as an open opening.

[0033] When the closing plate 3 moves the electromagnet downwards, the electromagnet loses its power and magnetism. The magnetic grinding mud falls into the collection frame 10 under the action of gravity, and then falls from the collection frame 10 into the collection pipe 7. The motor 83 in the collection pipe 7 drives the main shaft 81 to rotate. Under the action of the blades 82, the magnetic grinding mud is transported to one side of the collection pipe 7 and falls out of the outlet to be collected.

[0034] Furthermore, the drive mechanism 9 includes sleeves 91 located on both sides of the drum 2. The sleeves 91 are rotatably connected to the collecting pipe 7. A second motor 92 is mounted on the frame. The second motor 92 is connected to the sleeves 91 via a gear set 93. The second motor 92 drives the gear set 93 to rotate, which in turn drives the sleeves 91 to rotate, and ultimately drives the drum 2 to rotate.

[0035] The working principle of this embodiment is as follows:

[0036] Wastewater filled with magnetic sludge is guided into wastewater tank 1. Then, motor 2 (92) drives drum 2 to rotate. As drum 2 rotates, it causes the closing plate 3 and electromagnet to rotate. When the adjusting rod 6 has not rotated to the adjusting notch 41, it is in close contact with the conductive ring 5, thus supplying power to the electromagnet. The electromagnet is magnetic. When the closing plate 3 and the electromagnet rotate below drum 2 and are submerged in the wastewater, the electromagnet attracts the magnetic sludge in the wastewater. The electromagnet slowly rotates to a higher position along with drum 2. When the adjusting rod rotates to the adjusting notch on the support rod at the higher position... At 41, the adjusting rod moves downward under the action of gravity, which causes the closing plate 3 and the electromagnet to move downward. At this time, the adjusting rod disengages from the conductive ring 5, de-energizing the electromagnet and causing it to lose its magnetism. The magnetic sludge previously adsorbed by the electromagnet falls downward into the collection pipe 7 under the action of gravity, and is then conveyed out of the collection pipe 7 by the conveying mechanism 8. As the drum 2 continues to rotate, the adjusting rod 6 moves out of the adjusting notch 41 and contacts the conductive ring 5 again, causing the electromagnet to be re-energized and regain its magnetism. The drum 2 is then immersed in the wastewater again to adsorb the magnetic sludge.
