Description

Technical Field

[0001] This utility model relates to the field of aluminum waste processing technology, and in particular to an aluminum flux addition device for aluminum waste smelting and recycling. Background Technology

[0002] Aluminum scrap recycling can reduce primary bauxite mining; for every ton of scrap aluminum recycled, approximately 4 tons of bauxite can be saved. Currently, 75% of the world's aluminum production is still in use; recycling enables resource reuse and alleviates pressure on mineral resources.

[0003] Aluminum scrap is generated during aluminum recycling and production. This scrap has the value of being remelted to extract aluminum. During the aluminum scrap smelting and recycling process, various additives need to be added, including but not limited to sodium chloride, potassium chloride, sodium fluoride, and calcium chloride. These additives can remove impurities, facilitate their floating, form easily separable compounds, and lower the melting point. However, these additives are usually added during the stirring of the molten aluminum. The existing additive addition process is prone to causing aluminum splattering, and the melting state of the additives cannot be effectively judged. Large particles of additives sink to the bottom of the molten aluminum, which affects their effectiveness. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing an aluminum flux addition device for aluminum scrap smelting and recycling.

[0005] This utility model is achieved through the following technical solution:

[0008] The bottom of the feeding tube extends into the inner side of the top of the rotating hood to prevent the falling additive from having too great an impact on the molten aluminum, and at the same time to shield the splashes caused by the impact.

[0009] In a preferred embodiment of this utility model, the retaining ring is disposed on the bottom outer side of the connecting ring, and the outer edge of the retaining ring does not contact the inner side of the connecting rod;

[0010] The retaining ring shields the splashed molten aluminum, protecting the bearing used to connect the connecting ring and the feeding pipe, and preventing molten aluminum from entering and affecting the bearing rotation.

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings.

[0021] like Figure 1-4 The aluminum flux addition device for aluminum scrap smelting and recycling shown includes a feeding pipe 1, a handle 2, a motor 3, a gear 4, a protective cover 5, a retaining ring 6, and a rotating mechanism 7. The handle 2 is fixedly installed at the top of the feeding pipe 1, the motor 3 is fixedly installed on the outside of the feeding pipe 1, the gear 4 is fixedly installed at the output end of the motor 3, the protective cover 5 is fixed to the outer surface of the feeding pipe 1, the retaining ring 6 is fixedly installed on the outside of the feeding pipe 1, and the rotating mechanism 7 is movably connected to the bottom outer side of the feeding pipe 1. The rotating mechanism 7 includes a connecting ring 71, a toothed ring 72, a connecting rod 73, a rotating cover 74, and a toggle plate 75. The connecting ring 71 is movably connected to the bottom outer side of the feeding pipe 1 through a bearing, the toothed ring 72 is fixedly installed on the outside of the connecting ring 71, the connecting rod 73 is fixedly installed on the bottom outer side of the connecting ring 71, the rotating cover 74 is fixedly installed at the bottom end of the connecting rod 73, and the toggle plate 75 is fixedly installed on the inner side of the bottom of the rotating cover 74.

[0022] Specifically, the bottom end of the feeding pipe 1 extends through and to the top inner side of the rotating cover 74. The bottom of the rotating cover 74 has a frustum-shaped structure. Melting holes are opened on the surface of the rotating cover 74. The retaining ring 6 is located on the bottom outer side of the connecting ring 71. The outer edge of the retaining ring 6 does not contact the inner side of the connecting rod 73. The gear 4 meshes with the gear ring 72. The protective cover 5 is sleeved on the outside of the gear 4 and the gear ring 72. The top of the protective cover 5 has a mounting hole that matches the output end of the motor 3. A feeding port is opened on the top outer side of the feeding pipe 1.

[0023] In this embodiment, the rotating cover 74 is first immersed in molten aluminum by controlling the handle 2. Then, the aluminum flux to be added is added into the feeding tube 1 through the feeding port opened on the top of the outer side of the feeding tube 1. The aluminum flux slides down into the rotating cover 74 along the inclined feeding tube 1. At this time, some molten aluminum splash will be generated. The splashed molten aluminum will be blocked by the top of the rotating cover 74 and the baffle ring 6. The baffle ring 6 also effectively prevents the splashed molten aluminum and the connecting ring 71 from contacting the bearing connected to the feeding tube 1, so as not to damage the bearing.

[0024] Furthermore, the drive motor 3 rotates, causing the gear 4 at the output end of the motor 3 to drive the gear ring 72 on the outside of the connecting ring 71 to rotate, thereby causing the rotating cover 74 to rotate. The protective cover 5 effectively shields the rotating gear 4 and gear ring 72, providing protection. As the molten aluminum flows into the melting holes on the surface of the rotating cover 74 and comes into contact with the aluminum flux, the molten aluminum containing the aluminum flux will be thrown out under the centrifugal force generated by the rotation, thereby achieving effective mixing. During the rotation, the agitator 75 agitates large particles of aluminum flux, facilitating melting. The frustum-shaped structure at the bottom of the rotating cover 74 automatically collects the remaining aluminum flux when the motor 3 stops. Large particles of aluminum flux cannot pass through the melting holes on the surface of the rotating cover 74, preventing them from directly settling. The additive addition status can also be judged by observing the remaining aluminum flux in the rotating cover 74, thereby achieving the ideal addition effect and facilitating the molten aluminum recovery work.

[0025] It should be noted that the parts not covered in this utility model are the same as or can be implemented using existing technology; the various drives in this utility model can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, and motors in conjunction with connecting rods, guide rods, etc., and are not limited to the structures described in the specification and the drawings.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
