Description

Technical Field

[0001] The present application relates to the technical field of recycled aluminum smelting, and in particular to a complete set of equipment for recycling recycled aluminum smelting ash and a slag cleaning process thereof. Background Art

[0002] Recycled aluminum is metallic aluminum formed by remelting scrap aluminum and removing impurities. In addition to aluminum, scrap aluminum also contains impurities of various substances. During the smelting process, the flammable impurities are burned into ashes due to the high temperature, and the lighter impurities will float on the surface of the molten aluminum to form ash.

[0003] The utility model patent with announcement number CN204039473U discloses a complete set of rotary furnace equipment, including a rotary furnace body with a feed port on it; a vibrating feeder for adding recycled aluminum raw materials into the rotary furnace body; a burner system for heating, melting and keeping warm the recycled aluminum raw materials in the rotary furnace body; a soup ladle for containing molten aluminum liquid produced after smelting the recycled aluminum raw materials; a slag ladle for containing slag produced after smelting the recycled aluminum raw materials; a PLC control system for controlling the electrical and mechanical operation of the rotary furnace complete set of equipment and participating in the control of the smelting process; wherein the vibrating feeder is arranged opposite to the feed port of the rotary furnace body, and the soup ladle and the slag ladle can be slidably fitted under the feed port of the rotary furnace body.

[0004] Regarding the above-mentioned related technologies, the ash still contains a certain amount of aluminum. After the ash in the furnace has been gathered for many times, the ash can be re-melted to further extract the internal aluminum to improve the yield. Re-melting requires a higher temperature. The above-mentioned method of pouring out the ash, because the aluminum liquid in the furnace has been poured out, the ash is easy to stick to the bottom of the furnace, and the inclination angle of the furnace body is limited, making it difficult to pour out the internal ash. Manual slag removal is still required. The working environment of manual slag removal is poor and there are safety hazards. Summary of the invention

The two ends of the oil cylinder 23 are respectively fixed to the bottom plate 21 and the top plate 22. The extension and retraction of the oil cylinder 23 can drive the top plate 22 to rise and fall. The loading mechanism 3 is arranged on the top plate 22. When the top plate 22 is lowered, the height of the loading mechanism 3 is also lowered, so that personnel can put the materials to be smelted into the loading mechanism 3 conveniently.

The electric slider 42 is fixed with a pull rod 43, and the lower end of the pull rod 43 is hinged with a collecting barrel 5.

[0054] A slag blocking plate 53 is fixed to one side of the top of the collecting barrel 5 , and a plurality of liquid holes 54 are opened on the slag blocking plate 53 . The electric slider 42 is hinged to an oil cylinder 1 44 , and the other end of the oil cylinder 1 44 is hinged to the collecting barrel 5 .

[0058] Example 2

[0059] A slag cleaning process for recycling recycled aluminum smelting ash, using a complete set of equipment for recycling recycled aluminum smelting ash of embodiment 1, comprising the following steps:

[0060] Step S1: Before pouring the primary ash into the feeding mechanism 3, the oil cylinder 23 is controlled to be shortened to move the feeding mechanism 3 downwards close to the ground. The primary ash (ash produced by the first smelting of scrap aluminum) is input into the furnace body 11 through the feeding mechanism 3, and the rotary furnace 1 is started to melt the primary ash at a smelting temperature of 800-850°C.

[0061] The temperature of the first smelting of scrap aluminum is 600-700℃. In order to extract more aluminum, the smelting temperature is increased during the second smelting. During the smelting process, the ash and the newly molten aluminum are gradually separated, and the ash floats on the surface of the aluminum.

[0062] Step S2: After the smelting is completed, the lid of the furnace body 11 is opened, and the ash and slag are gathered to one side of the inner wall of the furnace body 11 by rotating the furnace body 11. The principle is: Figure 6 Taking the counterclockwise rotation of the furnace body 11 as an example, when the inclined furnace body 11 rotates, the inner wall of the furnace body 11 will drive the contacted molten aluminum to move, thereby bringing the liquid on the right end of the molten aluminum surface into the depth, and bringing the liquid on the left end of the molten aluminum out to the surface of the molten aluminum, thereby generating a phenomenon of rightward flow at the molten aluminum liquid surface. Based on this principle, the ash slag gathers on the right side of the furnace body 11.

[0063] Step S3: Push the trolley 2 close to the mouth of the furnace body 11, control the electric slider 42 to move toward the furnace body 11, control the extension and retraction of the oil cylinder 23, so that the front section 51 of the tube enters the furnace body 11, and the rear section 52 of the tube is located at the mouth of the furnace body 11, and the front section 51 of the tube is completely immersed in the aluminum water, the axis of the front section 51 of the tube is horizontal, and the slag baffle 53 protrudes from the surface of the aluminum water.

[0064] Step S4: Refer to Figure 7 , the furnace body 11 is rotated in the reverse direction (the rotation direction in this embodiment is clockwise) to move the slag on the surface of the molten aluminum to the other side, so that the slag is blocked by the slag blocking plate 53. The principle of slag movement has been explained in step S2 and will not be repeated here.

[0065] Step S5: Control the oil cylinder 23 to extend, and raise the height of the front section 51 to lift it away from the surface of the molten aluminum. Then, the ash enters the front section 51, and the molten aluminum in the front section 51 flows out from the front end of the front section 51 and the leakage hole 55.

[0066] In the process of moving the front section 51 upward, the oil cylinder 44 is controlled to extend slightly, so that the front end of the front section 51 is slightly tilted, thereby preventing the ash from leaving the collecting tube 5 from the front end of the front section 51. After the front section 51 completely leaves the aluminum liquid, the ash in the front section 51 enters the rear section 52 for temporary storage.

[0067] Step S6: Control the electric slider 42 to move in a direction away from the furnace body 11 , so that the collecting tube 5 is retracted into the trolley 2 , and the trolley 2 is pushed away from the furnace body 11 .

[0068] Step S7: Place a container below the front end of the barrel front section 51, control the oil cylinder 44 to shorten and tilt the collecting barrel 5, the front end of the collecting barrel 5 tilts downward, and the ash in the collecting barrel 5 is poured into the container from the front end of the barrel front section 51 to complete the slag cleaning.

[0069] In summary, through this equipment and its slag cleaning process, manual slag removal can be avoided, and the harsh working environment and safety hazards of manual slag removal can be avoided. Through the controller, most of the actions of cylinder 1 44 and cylinder 2 23 can be automatically operated in this application, thereby reducing the amount of human operation.

[0070] By means of the equipment and its slag cleaning process, slag removal is completed before pouring out the molten aluminum. Compared with the existing form of filtering ash slag through a filtering structure during the pouring process of the molten aluminum, the problem of ash slag leaking into the mold along with the molten aluminum is avoided, thereby improving the quality of the molten aluminum after casting, and also avoiding the problem of a large amount of ash slag clogging the filtering structure, and also reducing the situation where the ash slag sticks to the inner wall of the furnace body 11 and is difficult to clean.

[0071] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
