The storage structure can store the recycled aluminum raw materials, and the heating structure can heat and melt the recycled aluminum raw materials inside the storage structure. Such a melting furnace can indeed achieve a good melting effect on the recycled aluminum raw materials during use. However, the stirring and melting furnace is not equipped with a good flue gas collection structure. When the melting structure heats and melts the recycled aluminum raw materials, the flue gas generated during the melting of the recycled aluminum raw materials will float in the air, which will cause damage to the physical health of the workers. At the same time, the existing stirring and melting furnace does not have a good furnace body transportation structure, which is not convenient for workers to transport the melted recycled aluminum raw materials.

Specific implementation manner

[0018] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners.

[0019] As Figures 1 - 3 shown, a stirring and melting furnace for recycled aluminum production includes a heating structure 7 and a melting crucible 8 detachably connected inside the heating structure 7. A moving structure is detachably provided at the lower part of the heating structure 7. The moving structure includes a connecting bottom plate 5. A housing 4 is fixedly connected to the connecting bottom plate 5. An air collecting hood 2 is fixedly connected to the upper end of the housing 4. A stirring structure is distributed on one side of the housing 4, and a blanking chute pipe 3 is distributed on the other side of the housing 4. The cross-section of the housing 4 is a semi-circular ring structure. An axial flow fan 1 is detachably connected to the upper end of the air collecting hood 2;

[0020] The heating structure 7 can be selected as a structure for heating the melting crucible 8 on the existing market. The melting crucible 8 can collect recycled aluminum raw materials. The heating structure 7 can drive the recycled aluminum raw materials inside the melting crucible 8 to be transported to the inside of the housing 4. The cavity formed by the housing 4 and the air collecting hood 2 can collect the flue gas generated during the melting of the recycled aluminum raw materials.

[0021] An electric slide rail 18 is detachably connected to the connecting bottom plate 5. A connecting chute 17 is provided at a position on the connecting bottom plate 5 opposite to the electric slide rail 18. The electric slide rail 18 and the connecting chute 17 are arranged side by side. The output end of the electric slide rail 18 is fixedly connected to a connecting base 6. The lower part of the connecting base 6 is slidably connected to the connecting bottom plate 5 through the connecting chute 17. The connecting base 6 is sleeved with the heating structure 7;

[0022] The electric slide rail 18 can drive the connecting base 6 to slide on the connecting bottom plate 5. When the electric slide rail 18 drives the connecting base 6 into the inside of the housing 4, the cavity formed by the housing 4 and the air collecting hood 2 can collect the flue gas generated during the melting of the recycled aluminum raw materials. Subsequently, the axial flow fan 1 can discharge the flue gas generated during the melting of the recycled aluminum raw materials to the outside.

[0023] The stirring structure includes a connecting support plate 9, on which a lifting structure is detachably connected. At the part of the connecting support plate 9 facing away from the lifting structure, a driving motor 14 is detachably connected. The output end of the driving motor 14 is detachably connected with a stirring rod 15. At the lower part of the stirring rod 15, a stirring blade 16 is fixedly connected. The lifting structure includes a support hydraulic cylinder 11 detachably connected to the lower part of the connecting support plate 9. The fixed end of the support hydraulic cylinder 11 is fixedly connected with a connecting plate 12. On the connecting plate 12, an auxiliary sliding rod 10 is fixedly connected. The auxiliary sliding rod 10 penetrates through the connecting support plate 9. A rotating structure 13 is detachably connected to the connecting plate 12. The rotating structure 13 is detachably connected with the housing 4.

[0024] When the recycled aluminum raw materials are collected inside the melting crucible 8, the electric slide rail 18 drives the connecting base 6 into the housing 4. Subsequently, the rotating structure 13 can drive the stirring rod 15 into the housing 4. Then, the support hydraulic cylinder 11 can drive the connecting support plate 9 to slide on the auxiliary sliding rod 10. When the stirring rod 15 drives the stirring blade 16 into the melting crucible 8, the output shaft of the driving motor 14 can drive the stirring blade 16 through the stirring rod 15 to stir the recycled aluminum raw materials inside the melting crucible 8.

[0025] Working principle: When this melting furnace is in use, the staff first collects the recycled aluminum raw materials inside the melting crucible 8. Subsequently, the electric slide rail 18 drives the melting crucible 8 into the housing 4 through the connecting base 6. When recycled aluminum raw materials need to be added to the inside of the melting crucible 8, the staff removes the cover of the melting crucible 8, and then injects the recycled aluminum raw material feeding device into the inside of the melting crucible 8 through the feeding chute pipe 3. Then, the rotating structure 13 drives the stirring rod 15 into the housing 4. Then, the support hydraulic cylinder 11 can drive the connecting support plate 9 to slide on the auxiliary sliding rod 10. When the stirring rod 15 drives the stirring blade 16 to contact the recycled aluminum raw materials, the output shaft of the driving motor 14 can drive the stirring blade 16 through the stirring rod 15 to stir the recycled aluminum raw materials inside the melting crucible 8. At the same time, the heating structure 7 can heat the recycled aluminum raw materials through the melting crucible 8. It should be added that the cover of the melting crucible 8 can be selected as the cover structure for sealing the melting crucible 8 on the existing market. When recycled aluminum raw materials are added to the melting crucible 8, the flue gas generated by the melting of the recycled aluminum raw materials will be collected in the cavity formed by the housing 4 and the air collecting hood 2. Subsequently, the axial flow fan 1 can discharge the flue gas generated by the melting of the recycled aluminum raw materials. When the recycled aluminum raw materials are melted inside the melting crucible 8, the electric slide rail 18 drives the melting crucible 8 to reset through the connecting base 6.
