[0002] Ductile iron castings are a type of high-strength cast iron material. The graphite inside exists in a spherical form. This structure makes its comprehensive properties close to those of steel, combining the casting performance of cast iron with the mechanical properties of steel. It has many characteristics such as good impact resistance, ductility, and corrosion resistance. It is widely used in the manufacture of various mechanical parts with complex stress and high strength and toughness requirements. In the production process of ductile iron milling, in order to facilitate the premixing of powdered or granular additives such as carbon raisers and alloying elements (such as nickel iron and scrap copper), it is necessary to use some mixing devices for ductile iron casting raw materials.

[0003] However, in actual use, the mixing device for ductile iron casting raw materials can only agitate and mix the raw materials in the middle position of the device. The agitation coverage of the agitation blades on the outside of the agitation component has a certain blind spot, making it difficult to agitate and mix the raw materials in the outer position of the device. The overall mixing process is time-consuming and inefficient, which is not conducive to efficient mixing of ductile iron casting raw materials.

[0004] Now, a novel high-efficiency mixing device for ductile iron casting raw materials is proposed to address the above-mentioned shortcomings. Utility Model Content

[0024] The output shaft of the drive motor 8 is fixedly connected to the input shaft of the reducer 7. The output shaft of the reducer 7 is fixedly connected to the top of the stirring shaft 4. The stirring frame 3 is symmetrically distributed about the vertical center line of the stirring shaft 4. The stirring shaft 4 passes through the interior of the movable seat 5. The movable seat 5 is fixed to the top of the outside of the stirring shaft 4. The two sets of gears 19 are respectively meshed with the inner side of the internal gear ring 18.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, the drive motor 8 is started by the reducer 7 to drive the stirring shaft 4 to rotate. The rotation of the stirring shaft 4 can simultaneously drive the outer movable seat 5 and the turntable 20 to rotate. The rotation of the turntable 20 can simultaneously drive the two sets of connecting shafts 17 to rotate. The connecting shafts 17 can be driven to rotate by the gear 19. After the raw material is introduced into the mixing tank 2 through the feed cylinder 13, the stirring shaft 4 can cover and stir the raw material in the middle position. At the same time, the stirring frame 3 on both sides can stir and cover the raw material in the outer position inside the mixing tank 2, reducing the mixing blind zone inside the device and performing efficient mixing treatment of the ball mill casting raw material.

[0026] A feeding cylinder 13 is fixed inside the right side of the mixing tank 2, and a connection port 9 is fixed at the top of the feeding cylinder 13. An installation groove 10 is provided inside the bottom of the connection port 9, and a filter screen 11 is provided inside the installation groove 10. A handle 12 is hinged to the top of the filter screen 11. The connection port 9 is connected to the inside of the feeding cylinder 13.

[0027] Specifically, such as Figure 1 and Figure 3 As shown, after the filter screen 11 is inserted into the mounting groove 10, when external raw materials are fed through the filter screen 11, the filter screen 11 can be used to filter out some large impurities in the raw materials.

[0028] A side groove 14 is provided inside the right side of the mixing tank 2, and a fixing seat 15 is installed inside the side groove 14. A viewing plate 21 is fixed inside the fixing seat 15.

[0031] Working Principle: In use, this invention controls the drive motor 8 to start, which in turn drives the stirring shaft 4 to rotate via the reducer 7. Simultaneously, the rotation of the stirring shaft 4 drives the outer movable seat 5 and the turntable 20 to rotate. The rotation of the turntable 20, in turn, drives the two sets of connecting shafts 17 to rotate. The connecting shafts 17 rotate via the gear 19. After the raw material is introduced into the mixing tank 2 through the feed cylinder 13, the stirring shaft 4 covers and agitates the raw material in the middle position. Simultaneously, the rotating and revolving stirring frame 3 on both sides agitates and covers the raw material in the outer position inside the mixing tank 2, achieving efficient mixing of the ball mill casting raw material. During internal feeding, the filter screen 11 is inserted into the mounting groove 10. When external raw material is fed through the filter screen 11, it helps to remove large impurities. Furthermore, during the use of the device, a viewing plate 21 is fixed in the fixed seat 15 installed inside the right side of the mixing tank 2. The transparent viewing plate 21 can be used to check the stirring and mixing state of the materials inside the mixing tank 2 in real time. After the raw material mixing is completed, the bottom discharge port 1 can be opened to discharge it.
