Description

Technical Field

[0001] This utility model relates to the field of refining equipment technology, specifically a self-feeding refining equipment for smelting recycled metals. Background Technology

[0002] The current method of adding refining agents is manual, where small packets of refining agent are added to the furnace as a whole. The quantity and uniformity of the addition are very poor, resulting in uneven reaction with the molten metal in the furnace. This leads to low overall efficiency, serious waste, and manual addition is prone to causing molten metal to splash, posing a safety hazard.

[0003] A search of Chinese patent CN216639615U reveals an automatic feeding device for aluminum recycling smelting. This device can feed materials by sensing the furnace opening temperature, and can perform quantitative feeding. It has a simple structure and is easy to use.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. During the feeding process, the refining agent is conveyed to a fixed point through the conveying pipe. The refining agent cannot be fed evenly and it is difficult to mix quickly with the smelting recycled metal. This can easily affect the smelting effect of the recycled metal and reduce the feeding efficiency of the self-feeding refining equipment for smelting recycled metal. Utility Model Content

[0017] Firstly, this utility model is equipped with a fixed ring, a small gear, a large gear, a support frame, a conveying pipe, and a spiral blade. Motor 1 drives the small gear to rotate, which in turn drives the support frame to rotate through the meshing large gear. The conveying pipe for feeding rotates at a uniform speed. When Motor 2 is working, it drives the movable rod and the spiral blade to rotate. The refining agent enters the conveying pipe from the hopper through the connecting pipe. The spiral blade conveys the refining agent. The refining agent is uniformly fed through the linear array of feeding holes. The refining agent quickly mixes with the molten recycled metal, which solves the problem that the refining agent cannot be uniformly fed and is difficult to mix quickly with the molten recycled metal, which easily affects the molten recycled metal smelting effect. This improves the feeding efficiency of the self-feeding refining equipment for molten recycled metal.

[0018] Secondly, this utility model is equipped with a first bevel gear, a second bevel gear, a rotating rod, and a stirring blade. During the rotation of the moving rod, the rotating rod is driven to rotate through the meshing first and second bevel gears, thereby driving the stirring blade to rotate and stir the refining agent in the hopper, preventing the refining agent from solidifying and agglomerating, thus improving the practicality of the self-feeding refining equipment for smelting recycled metals.

One end of the output shaft of the motor 4 is connected to a movable rod 14 through a coupling. A spiral blade 15 is fixedly connected to the outer wall of the movable rod 14. A conveying pipe 8 is fixedly connected to the other outer wall of the base 5. A feeding hole 11 is opened on one outer wall of the top of the conveying pipe 8. A connecting pipe 7 is inserted into the inner wall of the feeding hole 11. A hopper 10 is fixedly connected to the other outer wall of the top of the support frame 6. Several feeding holes 11 are opened on the outer wall of the bottom end of the conveying pipe 8.

[0033] Furthermore, a connecting hole is provided on one side of the outer wall of the bottom end of the hopper 10, the connecting pipe 7 is inserted into the inner wall of the connecting hole, and the spiral blade 15 is slidably connected to the inner wall of the conveying pipe 8.

[0038] Working principle: During the smelting of recycled metal, when refining agent needs to be added, the refining agent is placed into the hopper 10. The temperature sensor 9 on the conveying pipe 8 detects the temperature above the furnace opening. When the temperature reaches the refining process temperature of recycled aluminum, the controller receives the signal from the temperature sensor 9 and then controls motor 2 and motor 4 to work. Motor 2 drives the pinion 3 to rotate, which in turn drives the support frame 6 to rotate through the meshing large gear 18. The conveying pipe 8 rotates at a constant speed. When motor 4 works, it drives the movable rod 14 and the spiral blade 15 to rotate. The refining agent enters the conveying pipe 8 from the hopper 10 through the connecting pipe 7. The spiral blade 15 conveys the refining agent. The refining agent is uniformly fed through the linear array of feeding holes 11. The refining agent quickly mixes with the smelted recycled metal.
