Description

Technical Field

[0001] This utility model relates to the technical field of aluminum-magnesium alloy powder production equipment, specifically to a safe and reliable aluminum-magnesium alloy powder production device. Background Technology

[0002] Currently, the existing method for producing aluminum-magnesium alloy powder involves first placing aluminum granules in a heating furnace, melting the aluminum granules, then adding magnesium and tin granules for smelting. After the molten metal is cleared, the slag is removed to obtain an alloy liquid. The alloy liquid is then poured into a mold and cooled to room temperature to obtain an alloy ingot. The alloy ingot is then machined into fine chips and pulverized to obtain alloy powder. The alloy powder is mixed with the liquid, and an organic binder is added and stirred evenly to prepare a metal powder slurry. The slurry is then processed into aluminum-magnesium alloy powder using a spray granulation machine.

[0003] In the above production process, in order to ensure product quality, it is necessary to ensure the purity of the alloy liquid, that is, to greatly reduce the presence of slag. However, the slag removal operation during smelting cannot completely remove the slag. Utility Model Content

In this embodiment, the upper surface of the rotatable base 12 is provided with a support 11 corresponding to the intermediate ladle 2, and the intermediate ladle 2 is provided with short shafts on both sides and supported on the support 11 by the short shafts. The support 11 is provided with a flipping motor 3 connected to the short shafts.

[0022] The filter cover mounting assembly and the filter cover disassembly assembly have the same structure. Taking the filter cover mounting assembly as an example, it includes a stand 6, a longitudinal lead screw and nut transmission mechanism 7 mounted on the stand 6, a horizontal support arm 4 connected to the lead screw and nut of the longitudinal lead screw and nut transmission mechanism 7, a guide mechanism located between the horizontal support arm 4 and the stand 6, a left linear module 9 and a right linear module 10 located on the lower surface of the horizontal support arm 4, and an L-shaped left hook 13 and an L-shaped right hook 14 connected to the sliders of the left and right linear modules. In this embodiment, the guide mechanism includes longitudinal guide rails 5 located on the left and right sides of the stand 6, and guide grooves located on the left and right sides of the horizontal support arm 4 and cooperating with the longitudinal guide rails 5.

[0023] The filter cover 15 consists of a filter section 1501 inserted into the upper port 1 and a flip section 1502 connected to the upper edge of the filter section 1501. The filter section 1501 is provided with a filter hole group, and the top surface of the intermediate package 2 is provided with a positioning structure 16 corresponding to the flip section 1502. The outer periphery of the flip section 1502 is provided with a left through hole 1503 and a right through hole 1504 corresponding to the L-shaped left hook 13 and the L-shaped right hook 14. In this embodiment, the upper port 1 of the intermediate package 2 is a tapered opening, and the upper part of the filter section 1501 of the filter cover 15 is provided with a tapered flared opening 1505 that matches the tapered opening. The positioning structure 16 consists of an inner positioning ring 1602 and an outer positioning ring 1601 concentric with the upper port 1, and the inner positioning ring 1602 and the outer positioning ring 1601 form a clamping space corresponding to the lower part of the flip section 1502. The lower surface of the horizontal support arm 4 is provided with a lifting cylinder 8. The lower end of the cylinder rod of the lifting cylinder 8 is provided with a positioning plug 17 that cooperates with the tapered flare 1505 of the filter cover 15. The lifting cylinder 8 is located between the left linear module 9 and the right linear module 10.

[0024] Working principle:

[0025] During operation, the heating furnace of the smelting unit is used to melt aluminum granules, magnesium granules, etc. into alloy liquid, and the alloy liquid is subjected to preliminary slag filtration.

[0026] Next, the rotatable base 12 drives the four intermediate ladles 2 on its upper surface to alternately reach the filling area near the heating furnace, and the heating furnace fills the molten alloy inside into the intermediate ladles 2 through the upper port.

[0027] After filling, the intermediate package 2, driven by the rotatable base 12, reaches the side where the filter cover mounting assembly is located. The L-shaped left hook 13 and L-shaped right hook 14 of the filter cover mounting assembly are pre-attached with the filter cover 15. The positioning plug 17 at the lower end of the cylinder rod of the lifting cylinder 8 presses against the conical flared opening 1505 of the filter cover 15, keeping the filter cover 15 stable. Driven by the longitudinal lead screw and nut transmission mechanism 7, the horizontal support arm 4 moves downward, driving the attached filter cover 15 downward. The filter cover 15 is pushed into the upper port 1 of the intermediate package 2, and the lower part of the flipping part 1502 of the filter cover 15 is inserted into the clamping space formed by the inner and outer positioning rings, achieving positioning.

[0028] After the filter cover 15 is installed, the intermediate ladle 2, driven by the rotatable base 12, reaches the mold forming area. The intermediate ladle 2 rotates under the action of the flipping motor 3, and the alloy liquid is filtered again through the filter cover 15 before being poured into the mold in the mold forming area. After all the alloy liquid has been poured, the intermediate ladle 2 rotates in the opposite direction to reset. The alloy liquid cools to room temperature in the mold, yielding an alloy ingot. The alloy ingot is sent to the crushing unit for crushing to obtain alloy powder. The alloy powder is then mixed with the liquid using the slurry preparation unit, and an organic binder is added and stirred evenly to prepare a metal powder slurry. Finally, the slurry is atomized into aluminum-magnesium alloy powder using the powder atomization unit.

[0029] After the alloy liquid is poured out, the intermediate ladle 2, driven by the rotatable base 12, reaches the side where the filter cover disassembly assembly is located. The longitudinal screw and nut transmission mechanism 7 of the filter cover disassembly assembly drives the horizontal support arm 4 to descend to the set position. The left and right linear modules drive the L-shaped left hook 13 and L-shaped right hook 14 to move relative to each other. The opposite ends of the L-shaped left hook 13 and L-shaped right hook 14 are respectively inserted into the left through hole 1503 and right through hole 1504 of the flip part 1502 of the filter cover 15. The longitudinal screw and nut transmission mechanism 7 moves in the opposite direction, the horizontal support arm 4 moves upward, and drives the attached filter cover 15 upward. The filter cover 15 disengages from the upper port 1 and the positioning structure 16.

[0030] Finally, the tundish 2 returns to the filling area near the heating furnace under the action of the rotatable base 12. Throughout the process, there is no need for manual attachment or removal of the filter cover 15 to the upper port 1 of the tundish 2, ensuring safety and reliability while achieving the purpose of secondary filtration of the alloy liquid and guaranteeing product quality.

[0031] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
