Description

Technical Field

[0001] This utility model relates to the field of aluminum chip iron removal technology, and in particular to an aluminum chip iron removal device. Background Technology

[0002] In the current metal processing industry, aluminum is a widely used metal, and the recycling of aluminum shavings generated during its processing is receiving increasing attention. Aluminum shavings recycling can not only reduce production costs but also conform to the environmental protection concept of sustainable development. However, aluminum shavings are often mixed with impurities such as iron filings. If they are not effectively removed, they will seriously affect the quality of recycled aluminum, such as reducing the strength, toughness and other performance indicators of aluminum alloys. Therefore, efficient iron removal technology for aluminum shavings has become a key research direction in this field.

[0003] The prior art (announcement number: CN221452901U) discloses an iron removal device for recycled aluminum chips, which disperses aluminum chips by vibrating a vibrating bed, and then the aluminum chips flow through a permanent magnet drum, where the magnetic field adsorbs iron chips in the aluminum chips, thereby achieving iron removal and purification of the aluminum chips.

[0004] However, the existing technology still has some drawbacks: First, it relies on a vibrating bed to disperse aluminum chips. For damp and clumped aluminum chips, the vibration is not enough to completely break the iron chip coating, causing some iron chips to pass through the magnetic field with the aluminum chips. In particular, fine iron chips are prone to adhesion and residue. Second, the permanent magnet roller is used, and the magnetic field strength is not adjustable. It is impossible to optimize the adsorption force for iron chips of different particle sizes. Large iron chips may not be firmly adsorbed or fine iron chips may not be adsorbed sufficiently. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an aluminum chip iron removal device, which solves the problems of existing devices having difficulty removing iron from wet aluminum chips and being unable to adapt to the separation requirements of iron chips of different particle sizes, thereby achieving efficient removal of iron impurities from aluminum chips and improving the quality of aluminum chip recycling.

[0007] As a further description of the above technical solution: the hot air drying assembly includes a hot air blower and a drying cylinder. The hot air blower is disposed on one side of the drying cylinder, and an air inlet is provided on one side of the drying cylinder. The output end of the hot air blower sends hot air to the drying cylinder through the air inlet.

[0008] As a further description of the above technical solution: the drying cylinder is provided with a buffer strip inside.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Reference Figure 1-3 An embodiment of this utility model provides an aluminum shavings iron removal device, including a frame 1, a feeding hopper 2 fixedly installed on the frame 1, a hot air drying assembly 3 fixedly installed at the discharge port at the bottom of the feeding hopper 2, an auger device 4 installed at the discharge port of the hot air drying assembly 3, a primary removal device 5 arranged below the output end of the auger device 4, a first iron impurity collection box 8 arranged below the primary removal device 5; a secondary removal device 6 arranged to the right of the primary removal device 5, a second iron impurity collection box 9 arranged below the secondary removal device 6, a conveyor belt 7 arranged to the right of the secondary removal device 6, and an aluminum shavings collection box 10 arranged below the right side of the conveyor belt 7.

[0026] The aluminum shavings to be processed are poured into the discharge hopper 2. The aluminum shavings enter the hot air drying assembly 3 through the discharge port at the bottom of the discharge hopper 2 for drying. After the aluminum shavings are fully dried, they enter the auger device 4. The auger device 4 conveys the dried aluminum shavings to the primary removal device 5. In the primary removal device 5, large iron particles are adsorbed and removed, and the iron particles fall into the first iron impurity collection box 8. The aluminum shavings after passing through the primary removal device 5 continue to move to the right to the secondary removal device 6. In the secondary removal device 6, small iron particles are adsorbed and removed, and the iron particles fall into the second iron impurity collection box 9. The iron-removed aluminum shavings are conveyed to the aluminum shavings collection box 10 by the conveyor belt 7, completing the iron removal process of aluminum shavings. To prevent aluminum shavings from slipping on the conveyor belt 7, the upper surface of the conveyor belt 7 is provided with baffles 13 to prevent aluminum shavings from slipping.

[0027] Example 2, refer to Figure 1-3 The hot air drying assembly 3 includes a hot air blower 301 and a drying cylinder 302. The hot air blower 301 is located on one side of the drying cylinder 302, and an air inlet 303 is provided on one side of the drying cylinder 302. The output end of the hot air blower 301 sends hot air to the drying cylinder 302 through the air inlet 303. The hot air generated by the hot air blower 301 enters the drying cylinder 302 and dries the aluminum chips that enter the drying cylinder 302 through the discharge hopper 2, breaking up the clumps formed by the aluminum chips due to moisture, and fully exposing the iron chips for subsequent iron removal. The drying cylinder 302 is equipped with a buffer strip 304, which can slow down the falling speed of the aluminum chips and prolong the contact time between the aluminum chips and the hot air in the drying cylinder 302, thereby improving the drying effect.

[0028] Example 3, referring to Figure 2 The primary removal device 5 includes a first vibrating bed 501 and a primary electromagnetic drum 502. The primary electromagnetic drum 502 is rotatably connected to the right side of the first vibrating bed 501 and is powered by a servo motor. The first vibrating bed 501 can further disperse the aluminum chips, making the aluminum chips more evenly distributed. The primary electromagnetic drum 502 generates a magnetic field during rotation. The magnetic field strength of the primary electromagnetic drum 502 is 0.5T, which focuses on adsorbing large iron particles in the aluminum chips. When the adsorbed iron particles are rotated downwards with the primary electromagnetic drum 502, they fall into the first iron impurity collection box 8 due to gravity.

[0029] The secondary removal device 6 includes a second vibrating bed 601 and a secondary electromagnetic drum 602. The secondary electromagnetic drum 602 is rotatably connected to the right side of the second vibrating bed 601 and is powered by a servo motor. The second vibrating bed 601 and the first vibrating bed 501 have the same function, which is to further disperse the aluminum chips after the primary removal device 5. The secondary electromagnetic drum 602 generates a magnetic field during rotation. The magnetic field strength of the secondary electromagnetic drum 602 is 1.3T, which is used to enhance the adsorption of the fine iron chips remaining after the primary iron removal. The adsorbed fine iron chips fall into the second iron impurity collection box 9.

[0030] Furthermore, both the primary electromagnetic roller 502 and the secondary electromagnetic roller 602 are provided with scrapers 11 on one side for scraping off iron filings. The scrapers 11 can promptly scrape off the iron filings adsorbed on the surface of the electromagnetic rollers, preventing the accumulation of iron filings from affecting the adsorption effect of the electromagnetic rollers.

[0031] Furthermore, the upper surfaces of the first vibrating bed 501 and the second vibrating bed 601 are both inclined to the right, so that the aluminum chips can move to the right under the action of vibration and pass through the primary electromagnetic roller 502 and the secondary electromagnetic roller 602 in sequence; baffles 12 are integrally formed on both sides of the first vibrating bed 501 and the second vibrating bed 601 to prevent the aluminum chips from falling from both sides during vibration.

[0032] Working principle: The aluminum shavings to be processed are poured into the feeding hopper 2. The aluminum shavings enter the drying cylinder 302 of the hot air drying component 3 through the discharge port at the bottom of the feeding hopper 2. The hot air generated by the hot air blower 301 dries the aluminum shavings. Under the action of the buffer bar 304, the aluminum shavings are fully dried and then enter the auger device 4. The auger device 4 conveys the dried aluminum shavings to the first vibrating bed 501. The aluminum shavings are dispersed and move to the right under the vibration of the first vibrating bed 501. When passing through the primary electromagnetic drum 502, large iron particles are adsorbed on the surface of the primary electromagnetic drum 502. When it rotates to the bottom, it is scraped off by the scraper 11 to the first iron impurity collection box 8.

[0033] The aluminum chips after primary iron removal continue to move to the right to the second vibrating bed 601, where they are shaken apart again and pass through the secondary electromagnetic roller 602. Fine iron chips are adsorbed on the surface of the secondary electromagnetic roller 602 and scraped off by the scraper 11 to the second iron impurity collection box 9. The iron-removed aluminum chips are then conveyed by the conveyor belt 7 to the aluminum chip collection box 10, completing the aluminum chip iron removal process.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
