Description

Technical Field

[0001] This invention relates to the field of spheroidizing agent cooling device technology, specifically a cooling plate structure for spheroidizing agent production. Background Technology

[0002] Spheroidizing agents are certain metals or alloys added to molten iron to obtain spheroidal graphite cast iron. In China, ferrosilicon, rare earth, and magnesium spheroidizing agents are commonly used, and the development of spheroidizing agents has played a crucial role in promoting spheroidal graphite cast iron production. Cerium was one of the earliest identified spheroidizing agents; however, at that time, cerium was scarce, and the requirements for molten iron composition were stringent, making cerium-based spheroidal graphite cast iron unsuitable for industrial production. Magnesium spheroidizing agents enabled the industrial-scale production and application of ductile iron. The development of spheroidizing agents from pure magnesium to magnesium-nickel, magnesium-copper, and magnesium-silicon-iron alloys promoted the expansion of ductile iron production. The development of rare earth magnesium-silicon-iron spheroidizing agents has enabled my country's ductile iron production to be basically based on domestic resources, establishing my country's rare earth magnesium ductile iron series, expanding the scope of pig iron use, improving the performance and quality of ductile iron castings, and making ductile iron production more vigorous. The application of yttrium heavy rare earths has created conditions for the development of new composite spheroidizing agents. The comprehensive utilization of various spheroidizing elements will create favorable conditions for the further development and improvement of ductile iron production. After processing, the spheroidizing agent itself will have a large amount of heat, which requires cooling treatment. Cooling pans are usually used to cool the spheroidizing agent.

[0003] However, existing spheroidizing agent cooling pans have the following problems during use: While they typically provide good cooling for the portion of the spheroidizing agent in contact with the pan, they are less efficient at cooling other parts of the agent. Furthermore, stacking the spheroidizing agent can lead to heat dissipation difficulties. Therefore, existing cooling methods are inefficient at cooling the spheroidizing agent. Consequently, a corresponding technical solution needs to be designed to address these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a cooling plate structure for the production of spheroidizing agents, which solves the technical problem that existing cooling plates typically have a good cooling effect on the part of the spheroidizing agent in contact with the cooling plate, but poor cooling efficiency on other parts of the spheroidizing agent. In addition, if the spheroidizing agent is stacked, heat dissipation is difficult. The existing cooling method has poor cooling efficiency for spheroidizing agents.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-5 This invention provides a technical solution: a cooling plate structure for spheroidizing agent production, including a spheroidizing agent cooling device. The spheroidizing agent cooling device includes a cooling body 1, a spheroidizing agent conveyor 2, a water-cooled cooling channel 3, and a vibrator 4. A guide cavity 5 is formed on the upper part of the cooling body 1. The spheroidizing agent conveyor 2 is installed inside the guide cavity 5. The water-cooled cooling channel 3 is installed above the spheroidizing agent conveyor 2 and includes a cooling channel 6 and a feed funnel 7 installed at the end of the cooling channel 6. A blower 8 is provided on one side of the cooling body 1. A gas collection hood 9 is installed at the outlet of the blower 8. The gas collection hood 9 is connected to an airflow pipe 10. The airflow pipe 10 is connected to a guide pipe 11. The guide pipe 11 is located inside the cooling channel 6. The vibrator 4 is divided into four groups and evenly installed at the corners of the cooling body 1. The vibrator 4 includes a base 12, a bracket 13, a floating column 14, an electric push rod 15, and a floating rod 16. The upper part of the base 12 is connected to the bracket. The bracket 13 is connected to the support 13. The floating column 14 is inserted longitudinally through the top of the support 13. The electric push rod 15 is installed on one side of the base 12 and its power output end is connected to the floating rod 16. The floating rod 16 is located below the floating column 14. The spheroidizing agent is introduced from the water-cooled cooling channel 3 into the interior of the water-cooled cooling channel 3 and transported by the spheroidizing agent conveyor 2. Water cooling treatment is carried out during the transportation process. In addition, the blower 8 installed at the bottom of the cooling body 1 performs air cooling treatment on the bottom of the spheroidizing agent. The vibrator 4 installed at the bottom of the cooling body 1 can vibrate the cooling body 1, so that the spheroidizing agent is bumped during the movement, so that the spheroidizing agent is loosened, avoiding the spheroidizing agent from piling up and improving the cooling effect of the spheroidizing agent. The spheroidizing agent cooling equipment designed in this invention can automatically transport, water cool, air cool, and loosen the spheroidizing agent, thereby achieving the purpose of automatic and efficient heat dissipation of the spheroidizing agent.

[0024] Further improvements, such as Figure 1 As shown: Both the spheroidizing agent conveyor 2 and the cooling channel 6 are machined into a serpentine structure. A water inlet pipe is connected to one side of the cooling channel 6 and a discharge port 17 is opened at the end. This design can extend the path length of the spheroidizing agent, thereby achieving a better cooling effect.

[0025] Further improvements, such as Figure 3As shown: the air guide pipe 11 is spirally arranged on the inner wall of the cooling channel 6 and several sets of nozzles 18 are installed on its surface. The nozzles 18 are inclined and the air outlets face downwards. The airflow is directed vertically onto the spheroidizing agent for air cooling through the nozzles 18.

[0026] Further improvements, such as Figure 4 As shown: The bracket 13 includes a U-shaped plate 19 and a top plate 20 installed on the top of the U-shaped plate 19. The U-shaped plate 19 has a movable cavity 21 inside, and the floating rod 16 is built into the movable cavity 21.

[0027] Further improvements, such as Figure 4 As shown: The floating column 14 is longitudinally inserted into the top plate 20 and includes a connecting column 22 and an elastic column 23 fitted into the lower end of the connecting column 22. The elastic column 23 is made of rubber and has a layered structure. This design makes it easy for the connecting column 22 to float up and down.

[0028] Further improvements, such as Figure 5 As shown: The floating rod 16 includes an adjusting rod 24, a vertical plate 25, and a swing rod 26. The adjusting rod 24 is fixed to the power output end of the electric push rod 15. The lower end of the vertical plate 25 has a notch 27. The outer end of the adjusting rod 24 is inserted into the notch 27. The swing rod 26 is located at the upper left corner of the vertical plate 25 and its upper end is connected to the bottom of the connecting column 22. The electric push rod 15 pushes the adjusting rod 24 to move laterally and pushes the vertical plate 25 to rotate 25. During the rotation of the vertical plate 25, the swing rod 26 floats up and down.

[0029] Further improvements, such as Figure 5 As shown: A pin 28 is inserted in the middle of the upright plate 25. The two ends of the pin 28 are rotatably connected to the inner wall of the U-shaped plate 19. The upper end of the upright plate 25 is processed into an arc-shaped structure to facilitate the rotation and adjustment of the upright plate 15.

[0030] Specifically, the lower end of the swing rod 26 is machined with a protruding ball 29. The height of the protruding ball 29 is lower than the height of the upper end of the vertical plate 25 and is used in conjunction with the vertical plate 25. This design makes it easy to move the protruding ball 29 up and down by moving it through the vertical plate 25, thereby achieving the purpose of longitudinal adjustment of the floating column 14.

[0032] In use: The present invention introduces the spheroidizing agent that needs to be cooled from the feed funnel 7 and conveys it through the spheroidizing agent conveyor 2. During the conveying process, water is introduced into the inner wall partition of the cooling channel 6 through the water inlet pipe to cool the spheroidizing agent inside. In addition, the blower 8 introduces the airflow into the air collection hood 9 and into the air guide pipe 11 through the airflow pipe 10. The nozzle 18 installed on the air guide pipe 11 performs air cooling treatment on the spheroidizing agent inside. In addition, the electric push rod 15 pushes the adjusting rod 24 to move reciprocally laterally and pushes the vertical plate 25 to rotate 25. During the rotation of the vertical plate 25, the upper arc surface structure acts on the convex ball 29, causing the convex ball 29 to float up and down through the swing rod 26, thereby achieving the purpose of vibrating the cooling body 1, causing the spheroidizing agent to vibrate and loosen, and achieving a better cooling purpose.
