This utility model is rationally designed. By providing a discharge structure on the outside of the smelting furnace structure, solvents and other materials to be added can be placed in advance. Furthermore, the subsequent feeding structure can stir the solvent placed inside the discharge structure, preventing solvent agglomeration. Simultaneously, the threaded feeding pipe can deliver the solvent from inside the discharge structure into the smelting furnace structure, thereby achieving automated and precise feeding of solvents and other materials.

Description

Technical Field

[0001] This utility model mainly relates to the field of castings, specifically to a feeding device for casting smelting. Background Technology

[0002] Casting production is the foundation of the equipment manufacturing industry, and one of its core processes is metal smelting. During the smelting process, adding alloying materials, solvents, and recycled materials to the smelting furnace (such as induction furnaces, electric arc furnaces, and cupola furnaces) is an essential and critical step. The accuracy, efficiency, and safety of the material feeding operation directly affect the chemical composition of the molten metal, temperature control, energy consumption, the final casting quality, and the production environment.

[0003] Currently, in foundry workshops, especially in small and medium-sized foundries, the smelting and charging process still widely employs traditional methods or semi-mechanized equipment with numerous drawbacks. Traditional manual charging relies mainly on operators using handcarts or forklifts to transport materials to the furnace, and then throwing or dumping them using shovels, buckets, and other tools. This method has significant shortcomings:

[0004] Poor feeding accuracy and unstable composition control: Manual weighing and feeding are difficult to guarantee accuracy, which can easily lead to batching errors. This results in fluctuations in the chemical composition of the molten metal, making it difficult to meet the strict requirements for composition control in high-end castings, leading to a decrease in product qualification rate and waste of raw materials.

[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

The driving gear 204 drives the rotating tube 301 to rotate through the driven gear 302, and the rotating tube 301 drives the threaded feeding tube 303 to rotate. The threaded feeding tube 303 feeds the solvent inside the discharge bin 201 into the auxiliary tube 206, and the solvent enters the discharge pipe 207 and enters the discharge pipe 209 through the slot 210. Then the solvent enters the melting furnace body 101 through the feed inlet 104.

[0031] During the rotation of the rotating tube 301, the rotating bar 304 is driven to rotate. The rotating bar 304 drives the stirring rod 306 to rotate via the vertical rod 305. The stirring rod 306 stirs the solvent placed inside the discharge bin 201. At the same time, the interior of the vertical rod 305 is connected to the rotating tube 301.

A discharge pipe 209 is slidably connected to the inner wall of the positioning pipe 208. A slot 210 is opened in the middle of the discharge pipe 209. A hook 211 on one side of the outer wall of the discharge bin 201 is attached to the outer wall of the placement strip 102 to fix the discharge bin 201. Then, solvents and other materials are put into the interior of the discharge bin 201 for storage.

[0034] Then, the second top cover 205 is placed on top of the feeding bin 201, and the discharge pipe 209 is pushed down. One end of the discharge pipe 209 is inserted into the inside of the feed port 104. Then, the servo motor 203 is started.
