Description

Technical Field

[0001] This utility model relates to the field of electrolytic aluminum production technology, specifically to an aluminum electrolytic bucket elevator magnetic separation belt iron removal device. Background Technology

[0002] In the electrolytic aluminum production process, the anode cover material is an important factor in maintaining the thermal balance of the electrolytic cell and preventing anode oxidation. Currently used anode cover materials have a high iron content due to various processes, iron oxide produced by long-term use of anode steel claws, iron filings produced by equipment wear, and other ironware. This results in a high iron content in the anode cover material, which seriously affects the quality of the primary aluminum.

[0003] Traditional bucket elevator material handling involves using a vibrating feeder to transport materials to the upper storage silo, where they are then added to a multi-functional overhead crane and finally fed onto the anode. This method fails to remove iron filings and iron oxide from the material, which then enter the electrolytic cell, leading to a decline in the quality of primary aluminum. Furthermore, it cannot accurately detect abnormalities in the electrolytic cell when iron content increases, increasing the risk of unsafe operation of the electrolytic cell. Utility Model Content

[0004] The purpose of this invention is to provide an aluminum electrolysis bucket lifting magnetic separation belt iron removal device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum electrolysis bucket lifting magnetic separation belt iron removal device, including a fixing frame, and further comprising: The cover is fixedly connected to the top of the fixed frame, and an electromagnetic iron remover is fixedly connected to the top of the cover. A servo motor is fixedly connected to a fixed frame. A rotating shaft and a fully magnetic conveying roller are rotatably connected inside the cover. The output end of the servo motor is fixedly connected to the rotating shaft. The rotating shaft and the fully magnetic conveying roller are connected by a conveyor belt.

[0006] Preferably, a scraper is fixedly connected to the inner wall of the cover, and the scraper is located at the lower part of the conveyor belt.

[0007] Preferably, the cover has a discharge port, and a receiving hopper fixedly connected to the cover is provided at the lower part of the discharge port.

[0008] Preferably, a feed hopper is fixedly connected to the top of the cover.

[0009] Preferably, the bottom of the cover is fixedly connected with several sets of fixing legs for supporting and fixing the cover.

[0010] Preferably, an adjusting bolt is installed on the fixed leg, and a pad is fixedly connected to the bottom of the adjusting bolt.

[0011] Preferably, the top of the cover is fixedly connected to two sets of mounting brackets, which are located on both sides of the electromagnetic separator.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, materials are transported via a conveyor belt to the bucket elevator. During transport, an electromagnetic iron separator is installed at the upper end of the conveyor belt to adsorb large iron particles from the material. A fully magnetic conveying roller is installed at the head end of the conveyor belt to separate all iron filings and iron oxide present in the material. The remaining material is then lifted into the bucket elevator hopper for use in the production workshop. This process removes impurities such as iron filings from the material, improves the quality of primary aluminum, and prevents abnormal conditions in the electrolytic cell caused by an increase in iron content, thereby improving the safe operation of the electrolytic cell.

[0016] Please refer to Figures 1-4. An aluminum electrolysis bucket lifting magnetic separation belt iron removal device includes a fixed frame 1, and further includes: a cover 2, fixedly connected to the top of the fixed frame 1, with an electromagnetic iron separator 3 fixedly connected to the top of the cover 2. After the electromagnetic iron separator 3 is energized, the electromagnetic coil generates a magnetic field, magnetizing the magnetic body to adsorb impurities such as iron filings; a servo motor 4, fixedly connected to the fixed frame 1, with a rotating shaft 5 and a fully magnetic conveying roller 6 rotatably connected inside the cover 2. The output end of the servo motor 4 is fixedly connected to the rotating shaft 5, and the rotating shaft 5 and the fully magnetic conveying roller 6 are connected by a transmission belt 7. The servo motor 4 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the fully magnetic conveying roller 6 to rotate synchronously through the transmission belt 7, using the fully magnetic conveying roller 6 to adsorb and trap impurities such as iron filings on the transmission belt 7.

[0017] It should be noted that: materials are transported via conveyor belt 7, which transports the materials to the bucket elevator hopper. During the transport process, an electromagnetic iron separator 3 is installed at the upper end of conveyor belt 7 to adsorb large iron particles in the materials. A fully magnetic conveying roller 6 is installed at the head end of conveyor belt 7 to separate all iron filings and iron oxide present in the materials. The remaining materials are lifted into the bucket elevator hopper for use in the production workshop.

[0018] A scraper 8 is fixedly connected to the inner wall of the cover 2. The scraper 8 is located at the lower part of the conveyor belt 7. The scraper 8 is inclined and the part that contacts the magnetic conveying roller 6 will adsorb iron filings. As the conveyor belt 7 moves, the adsorbed iron filings move to the scraper 8 and are scraped off and collected by the scraper 8.

[0019] The cover 2 has a discharge port 9, and a receiving hopper 10 is fixedly connected to the cover 2 at the lower part of the discharge port 9. The receiving hopper 10 is fixed to the bottom of the cover 2 by bolts. As shown in Figure 4, the discharge port 9 is located in front of the scraper 8, and the scraped impurities fall into the receiving hopper 10 through the discharge port 9 for collection.

[0020] A feeding hopper 11 is fixedly connected to the top of the cover 2, and the material is transported to the conveyor belt 7 inside the cover 2 through the feeding hopper 11.

The adjusting bolt 13 is threaded on the bottom of the fixed leg 12. By rotating the position of the adjusting bolt 13 on the fixed leg 12, the height of the fixed leg 12 can be adjusted so that the fixed frame 1 remains horizontal and stable.

[0022] Two sets of mounting brackets 14 are fixedly connected to the top of the cover 2. The two sets of mounting brackets 14 are located on both sides of the electromagnetic separator 3. Four sets of connecting buckles are welded to the top of the electromagnetic separator 3. The electromagnetic separator 3 can be installed and fixed on the mounting brackets 14 by passing iron chains through the connecting buckles. The height of the electromagnetic separator 3 can be adjusted by adjusting the length of the iron chains.

Their specific structures and working principles are common knowledge to those skilled in the art, and their combined application and parameter optimization are conventional technical means in this field, which will not be described in detail in this application. The material is transported by the conveyor belt 7, which transports the material to the bucket elevator. During the transportation process, the electromagnetic separator 3 installed at the upper end of the conveyor belt 7 adsorbs large iron particles in the material, and the all-magnetic conveying roller 6 installed at the head end of the conveyor belt 7 separates all iron filings and iron oxide present in the material. The remaining material is lifted by the bucket elevator to the bucket elevator hopper for use in the production workshop. The scraper 8 is set at an inclination, and the part in contact with the all-magnetic conveying roller 6 will adsorb iron filings. As the conveyor belt 7 moves, the adsorbed iron filings move to the scraper 8 and are scraped off by the scraper 8. The scraped-off impurities fall into the receiving hopper 10 through the discharge port 9 for collection.
