Description

Technical Field

[0001] The utility model relates to the technical field of waste aluminum processing equipment, in particular to a waste aluminum recovery and iron removal device. Background Art

[0002] Factories that produce aluminum or aluminum alloy products generate some scrap aluminum every day, such as incomplete products and scraps from the production process. This scrap aluminum is transported to designated locations for storage, and once accumulated, it is processed using scrap aluminum processing equipment for recycling and reuse.

[0003] During transportation and storage, scrap aluminum often picks up iron impurities such as iron filings or slag. Therefore, some scrap aluminum processing equipment incorporates iron removal mechanisms to remove these impurities to prevent them from affecting the purity of the aluminum during subsequent reuse. Publication No. CN220166256U, for example, discloses a scrap aluminum impurity removal device comprising an impurity removal box whose sidewalls are configured with a scrap aluminum feed port. The aforementioned patent utilizes a telescopic rod to drive a magnet that extends onto the upper surface of an inclined bottom plate to remove iron impurities from the scrap aluminum passing through the magnet. However, it is apparent from the aforementioned patent that, during use, if the magnet is too low, it will block the path of the crushed scrap aluminum, causing the scrap aluminum to pile up and resulting in poor iron removal. If the magnet is too high, there will be no contact between the magnet and the scrap aluminum for iron removal, and the iron impurities in the scrap aluminum will be blocked by the distance and the scrap aluminum, resulting in even poor iron removal.

This is a contact-type iron removal with better effect. The iron impurities are cleaned by the scraper and collection box at the bottom, further improving the iron absorption effect of the magnet layer of the drum.

[0023] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0024] According to the instruction manual Figure 1-3It can be seen that when the present invention is used, personnel manually or by using a feeding device feed the material to the feed port 7 of the box body 8, allowing the scrap aluminum to enter from the feed port 7 and be crushed by the crushing mechanism. The crushed scrap aluminum falls downward and falls on the drum 4. The drum 4 is connected to a pair of bottom plates 16 to form a cylindrical shape and is driven to rotate by the second rotating shaft 10 and the second motor 17. Different positions on the outer surface of the drum 4 come into contact with the continuously falling scrap aluminum, and the scrap aluminum also slides from the surface of the drum 4 to the bottom of the box body 8. Since a magnet layer 5 is provided on the outside of the drum 4, the magnet layer 5 can absorb the iron impurities in the scrap aluminum, and the iron impurities are cleaned by the scraper 12 under the drum 4. Figure 1 As shown, as the drum 4 rotates counterclockwise, iron impurities adsorbed on its surface are scraped off by the scraper 12 at its bottom, falling into the collection box. The scraper 12 is rotatably connected to the collection box 13 via a torsion spring 23 and a connecting shaft 24. The force of the torsion spring 23 creates a certain force between the scraper 12 and the drum 4, ensuring the scraping force. Even if there is a certain attraction between the iron impurities and the magnet layer 5, excessive accumulation will still cause them to fall off. Compared to the prior art, the iron impurities in the present invention can directly contact the magnet layer 5, achieving a more effective contact iron removal. Moreover, the iron impurities are cleaned by the scraper 12 at the bottom and the collection box, further enhancing the iron absorption effect of the magnet layer 5 of the drum 4.

[0025] The drum 4 is configured in the shape of axially arranged corrugations 11, and the side of the scraper 12 that contacts the drum 4 is configured to match the corrugations 11. The design of the corrugations 11 can divert scrap aluminum and iron impurities, increasing the contact area, reducing thickness, and improving iron removal efficiency. Wear-resistant rods 26 can also be installed at both ends of the scraper 12, allowing the wear-resistant rods 26 to contact the wear-resistant layer 27 of the bottom plate 16, bringing the scraper 12 closer to the surface of the drum 4, reducing wear on the magnet layer 5 and increasing service life.

[0026] The collection box 13 has an inclined baffle 3 on the upper end facing the other side of the scraper 12. This reduces the possibility of scrap aluminum entering the box and facilitates the collection of iron impurities. Furthermore, the collection box 13 has a plug 18 at one end and a handle 21 at the other. The housing 8 has a socket 25 on one side corresponding to the collection box 13 and a slot 22 on the other side. During use, the collection box 13 is inserted through the socket 25, allowing the plug 18 to fit into the slot 22. This makes the collection box 13 removable and facilitates the removal of iron impurities. It should be noted that the design of the socket 25 takes the presence of the scraper 12 into account, and those skilled in the art can implement this design using common sense.

[0027] Among them, an ejection mechanism is provided at the bottom of the box body 8, and an electric push rod 2 is provided on the outer wall on the other side of the bottom of the box body 8 corresponding to the discharge port 14. The telescopic end of the electric push rod 2 penetrates into the box body 8 and is connected to the push plate 1. When in use, the telescopic end of the electric push rod 2 extends to drive the push plate 1 to move to clean the scrap aluminum in the box body 8.

[0028] The crushing mechanism can utilize existing technology. One possible embodiment comprises a pair of first rotating shafts 6, a pair of crushing rollers 9, a first motor 15, and a gear train 19. The pair of first rotating shafts 6 are arranged in parallel and rotate through the upper portion of the housing 8. One end of the pair of first rotating shafts 6 extends through the housing 8 and is connected to the output end of the first motor 15 via the gear train 19. The other end of one of the first rotating shafts 6 extends through the housing 8 and is connected to the output end of the first motor 15. The first motor 15 is fixedly connected to the exterior of the housing 8. During operation, the first motor 15 drives the first rotating shafts 6 to rotate. Driven by the gear train 19, the two rotating shafts rotate in opposite directions, driving the pair of crushing rollers 9 to perform the crushing operation. A protective cover 20 may be provided on the exterior of the gear train 19.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
