Description

Technical Field

[0001] This utility model belongs to the field of aluminum ash processing technology, and in particular relates to an overlapping double roller iron removal pipe. Background Technology

[0002] Aluminum ash is a solid waste generated during the high-temperature smelting of aluminum alloys. It contains aluminum, alumina, and small amounts of other metallic impurities and is typically transported through dedicated pipelines. However, especially during the production process, small amounts of iron filings and other impurities may be mixed into the aluminum ash. These iron filings negatively impact the subsequent processing, recycling, and utilization of the aluminum ash, affecting its cleanliness and quality and reducing the efficiency of recycling. Therefore, effectively removing iron filings from aluminum ash pipelines, especially removing them without damage during the transportation process, has always been a major technical challenge in the aluminum ash processing industry.

[0003] While existing aluminum ash pipelines remove impurities through various filtration and separation systems during the aluminum ash transport process, their separation precision is low due to technical deficiencies. Although adding corresponding filtration and separation equipment at the beginning or end of the pipeline can significantly improve the results, it requires major overhaul of the entire pipeline system, which is costly and time-consuming.

[0006] The inner wall of the iron removal pipe is fixedly connected with a scraper and a distribution plate. The scraper is attached to the outer wall of the magnetic ring on the side away from the inner wall of the iron removal pipe. Iron outlets are opened on both sides of the iron removal pipe. The lower edge of the distribution plate is attached to the lower edge of the iron outlet, and the upper edge of the distribution plate is located below the rotating roller.

The head end of the connecting shaft extends out of the front of the iron removal pipe and is fixedly fitted with a toothed disc, and the two toothed discs mesh for transmission.

[0009] The drive mechanism also includes a motor and a cover plate. The cover plate is fixedly connected to the front of the iron removal pipe and covers the periphery of the gear plate.

[0011] As a preferred embodiment of the above technical solution, the cross-section of the material distribution plate is "L" shaped. The vertical part of the "L" shaped material distribution plate is located below the rotating roller and has a distance d between it and the outer edge of the magnetic ring. The distance d is greater than the thickness of the iron filings adsorbed by the magnetic ring. The horizontal part of the "L" shaped material distribution plate is inclined downward.

[0015] 2. This utility model adopts an overlapping design, which makes it easy to install directly on existing aluminum ash conveying pipelines without requiring large-scale modifications to the existing pipelines, thereby reducing the modification cost and construction period and making it highly adaptable.

[0016] 3. This utility model only requires a motor to drive the two rollers to rotate, without the need for additional high-energy-consuming equipment. It removes impurities only through physical means, avoiding chemical additives or complex mechanical separation processes, saving energy consumption, reducing environmental pollution, and conforming to the concept of green environmental protection.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0024] Example

[0025] like Figures 1-3 As shown, the overlapping double roller iron removal pipe includes a conveying pipe 10, an iron removal pipe 20 is fixedly connected to the front of the conveying pipe 10, two rotating rollers 50 are rotatably connected to the inside of the iron removal pipe 20, a magnetic ring 60 is fixedly sleeved on the outer periphery of the rotating rollers 50, a scraper 70 is fixedly connected to the inner wall of the iron removal pipe 20, and the side of the scraper 70 away from the inner wall of the iron removal pipe 20 is attached to the outer wall of the magnetic ring 60. A ash conveying pipe 40 is fixedly connected to both the conveying pipe 10 and the iron removal pipe 20.

[0026] This practical overlapping double-roller iron removal pipe adopts an overlapping design, which is convenient for direct installation on the existing conveying pipe 10 without the need for large-scale modification of the existing pipeline, thereby reducing the modification cost and construction period. During operation, the aluminum ash conveyed inside the conveying pipe 10 is transported to the iron removal pipe 20 through the ash delivery pipe 40. Then, the rotating roller 50, through continuous rotation, in conjunction with the magnetic ring 60 and scraper 70, can quickly and effectively adsorb and remove iron filings and other metal impurities from the aluminum ash, resulting in a significant iron removal effect. The inner bottom wall of the iron removal pipe 20 is designed with an inclination, and a return ash port 22 is opened at the bottom where the iron removal pipe 20 and the conveying pipe 10 meet, with the lower edge of the return ash port 22 fitting against the inclination lower edge of the inner bottom wall of the iron removal pipe 20. The aluminum ash after iron removal falls onto the inner bottom wall of the iron removal pipe 20, and then returns to the conveying pipe 10 along the inclination inner bottom wall through the iron removal pipe 20.

[0027] A material distribution plate 80 is fixedly connected to the inner wall of the iron removal pipe 20. Iron outlets 21 are opened on both sides of the iron removal pipe 20. The lower edge of the material distribution plate 80 is in contact with the lower edge of the iron outlet 21, and the upper edge of the material distribution plate 80 is located below the rotating roller 50. The cross-section of the material distribution plate 80 is "L"-shaped. The vertical part of the "L"-shaped material distribution plate 80 is located below the rotating roller 50 and has a distance d between it and the outer edge of the magnetic ring 60, and the distance d is greater than the thickness of the iron filings adsorbed by the magnetic ring 60. The horizontal part of the "L"-shaped material distribution plate 80 is inclined downwards. When the magnetic ring 60, which adsorbs iron filings, rotates to the scraper 70 position, the iron filings are scraped off onto the material distribution plate 80 and then discharged and collected from the iron outlet 21 along the inclined horizontal part of the "L" shape of the material distribution plate 80.

[0028] A drive mechanism 30 is provided on the front side of the iron removal pipe 20, and the drive mechanism 30 is used to drive the two rotating rollers 50 to rotate synchronously in opposite directions. In this application, the drive mechanism 30 is used to drive the two rotating rollers 50 to rotate synchronously in opposite directions. In practical applications, the drive mechanism 30 can be replaced with other drive components with the same function.

[0029] The drive mechanism 30 includes a connecting shaft 33 that is coaxially arranged with and fixed to the rotating roller 50. The head end of the connecting shaft 33 extends out of the front of the iron removal pipe 20 and is fixedly sleeved with a toothed disc 34. The two toothed discs 34 mesh and drive each other.

[0030] The drive mechanism 30 also includes a motor 31 and a cover plate 32. The cover plate 32 is fixedly connected to the front of the iron removal pipe 20 and covers the periphery of the gear plate 34. The cover plate 32 is fixedly connected to the front of the cover plate 32 and the output shaft is fixed to the head end of one of the connecting shafts 33.

[0031] In this embodiment, the working principle of the drive mechanism 30 is as follows: the motor 31 drives one of the connecting shafts 33 to rotate, and under the meshing transmission of the gear plate 34, it drives the two connecting shafts 33 to rotate synchronously in opposite directions, thereby driving the two rotating rollers 50 to rotate synchronously in opposite directions.

[0032] like Figure 4 As shown, the ash feeding pipe 40 includes an upper part and a lower part. The upper part is in the shape of a conical funnel, and the lower part is in the shape of an inclined tube. The discharge port of the lower part of the ash feeding pipe 40 is directly above the middle of the two rotating rollers 50.

[0033] This utility model is applicable to various types and specifications of aluminum ash pipes. It can adjust parameters such as the spacing and speed of the rotating roller 50 and the size of the ash feeding pipe 40 according to actual needs, making it highly flexible and adaptable to different production environments.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
