Description

Technical Field

[0001] This utility model belongs to the field of aluminum smelting technology, and in particular relates to an iron removal and dust elimination device for aluminum ash feeding. Background Technology

[0002] Aluminum ash is a byproduct of aluminum smelting, containing aluminum, aluminum alloys, alumina, and other impurities. The feeding process of aluminum ash is a crucial step in aluminum smelting, accompanied by the emission of ferromagnetic substances contained in the ash and a large amount of dust. Therefore, effectively removing ferromagnetic impurities (such as iron filings) and dust from aluminum ash is essential for improving the efficiency of aluminum ash feeding, reducing environmental pollution, and increasing recycling rates.

[0003] In existing technologies, iron removal and dust removal in aluminum ash feeding are usually performed as two separate steps. The iron removal step typically uses strong magnetic equipment (such as magnetic separators and permanent magnet separators) to extract magnetic materials; the dust removal step uses dust collection devices (such as bag filters and cyclone separators) to treat the dust generated during the feeding process. Although these two steps can effectively separate ferromagnetic materials from aluminum ash and remove dust, this process has the following technical drawbacks:

[0004] 1. Large equipment footprint: Since iron removal and dust removal are set up independently, multiple separate devices are often required, and the layout of these devices requires a large production space; the increased footprint will increase the investment cost, operating cost and waste of space.

[0005] 2. Complex equipment configuration: Since the iron removal and dust removal equipment work independently, the system configuration is complicated, making it difficult to achieve efficient and coordinated operation, which increases the difficulty of maintenance and management;

[0006] 3. Low operating efficiency: Different equipment operates independently during the aluminum ash feeding process, which may result in time gaps and process disconnects, leading to low overall processing efficiency, and the time required for each step of the operation cannot be optimized.

[0007] To address the aforementioned issues, we propose an iron removal and dust suppression device for aluminum ash feeding. Utility Model Content

[0008] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0009] A dust removal and iron removal device for aluminum ash feeding includes:

[0011] The material distribution mechanism includes a servo motor mounted on the front of the outer casing, a rotating shaft fixedly connected to the output shaft of the servo motor, a material distribution roller fixedly sleeved around the rotating shaft, and a magnetic cylinder detachably mounted around the material distribution roller.

[0012] As a preferred embodiment of the above technical solution, the inner wall of the outer casing is provided with a material guiding mechanism, and the material guiding mechanism is located between the inlet and the material distribution mechanism.

[0016] As a preferred embodiment of the above technical solution, a dust collection hood is fixedly connected to the top of the dust collection port, and the top of the dust collection hood is connected to an external dust collection device.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. This utility model integrates iron removal and dust removal functions within the outer casing, avoiding the need for multiple separate iron removal and dust removal devices as required by traditional technologies, thus significantly reducing the space occupied by the equipment.

[0024] 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.

[0025] Example

[0026] like Figures 1-3 As shown, the iron removal and dust elimination device for aluminum ash feeding includes:

[0027] The outer casing 10 has an L-shaped cross section. The stepped top of the outer casing 10 is provided with a feed inlet 11 and a dust removal inlet 12, with the feed inlet 11 being higher than the dust removal inlet 12. The outer casing 10 has an iron outlet 13 on the left side and a discharge outlet 14 on the bottom.

[0028] The material distribution mechanism includes a servo motor 41 mounted on the front of the outer casing 10, a rotating shaft 42 fixedly connected to the output shaft of the servo motor 41, a material distribution roller 43 fixedly sleeved around the rotating shaft 42, and a magnetic cylinder 44 detachably mounted around the material distribution roller 43.

[0029] The inner left wall of the outer casing 10 is fixedly connected with 51 and 52;

[0030] The end of 51 is close to the outer edge of the magnetic cylinder 44, and the lower edge of 52 is flush with the lower edge of the iron outlet 13.

[0031] The working principle of this practical aluminum ash feeding iron removal and dust elimination device is as follows: Aluminum ash is fed into the outer casing 10 from the feed port 11 and falls onto the upper surface of the magnetic cylinder 44. Under the magnetic attraction of the magnetic cylinder 44, the iron filings in the aluminum ash are adsorbed onto the outer surface of the magnetic cylinder 44. At the same time, the servo motor 41 drives the rotating shaft 42, the distributing roller 43, and the magnetic cylinder 44 to rotate clockwise continuously. During the rotation, the iron filings adsorbed on the outer surface of the magnetic cylinder 44 are continuously scraped off by 51 onto 52, and then discharged outward from the iron outlet 13. The area of ​​the magnetic cylinder 44 where the iron filings are scraped off will re-contact the continuously falling aluminum ash, and then re-adsorb the iron filings in the aluminum ash. This process is repeated to achieve the effect of eliminating iron filings in the aluminum ash.

[0032] A dust collection hood 30 is fixedly connected to the top of the dust collection port 12, and the top of the dust collection hood 30 is connected to an external dust collection device.

[0033] The aluminum ash from which the iron filings have been removed falls from the right side of the distributing roller 43. Due to the weight difference between aluminum ash and dust, the dust is drawn out through the dust collection port 12 and dust collection hood 30 by the negative pressure generated by the external dust collection equipment. The remaining aluminum ash is discharged outward from the discharge port 14. Thus, the iron removal and dust removal of aluminum ash are completed.

[0034] This utility model integrates iron removal and dust removal functions within the outer casing 10, avoiding the need for multiple separate iron removal and dust removal devices as required by traditional technologies, thus significantly reducing the space occupied by the equipment. This reduction in footprint saves production space, lowers factory construction and equipment installation costs, and ultimately improves the utilization efficiency of production space.

[0035] Furthermore, through its integrated design, aluminum ash can undergo iron removal and dust removal simultaneously during the feeding process, avoiding time gaps between separate operations and ensuring the continuity and efficiency of the entire processing. This integrated processing method significantly improves the processing speed of aluminum ash and increases production efficiency.

[0036] The inner wall of the outer casing 10 is provided with a material guiding mechanism 20, and the material guiding mechanism 20 is located between the feed inlet 11 and the material distribution mechanism. The material guiding mechanism 20 includes an upper inclined plate 21 and a lower inclined plate 22 fixedly connected to the inner wall of the outer casing 10, and the upper inclined plate 21 and the lower inclined plate 22 are arranged in opposite directions and staggered.

[0037] This utility model uses a guiding mechanism 20 to guide the aluminum ash fed into the feed inlet 11. In this utility model, the aluminum ash fed into the feed inlet 11 first falls onto the upper inclined plate 21, then falls onto the lower inclined plate 22 through the upper inclined surface of the upper inclined plate 21, and then falls onto the upper right outer inclined surface of the magnetic cylinder 44 through the upper inclined surface of the lower inclined plate 22, thereby achieving better iron removal and dust removal effects.

[0038] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
