Description

Technical Field

[0001] This utility model relates to the field of spheroidizing machine technology, specifically a novel spheroidizing machine for processing ductile iron castings. Background Technology

[0002] Cast iron is an iron-carbon alloy with a carbon content greater than 2.11%. It is obtained by melting and casting industrial pig iron, scrap steel and other steel and alloy materials at high temperature. In addition to Fe, it also contains carbon from other cast irons that precipitate in the form of graphite. Cast iron with graphite in the form of flakes is called gray cast iron, cast iron with graphite in the form of worms is called vermicular graphite cast iron, cast iron with graphite in the form of nodules is called malleable cast iron, and cast iron with graphite in the form of spheroids is called ductile iron. When ductile iron castings are produced, workers need to add spheroidizing agents and inoculants to the molten iron.

[0003] However, existing spheroidizing machines for ductile iron require the spheroidizing agent and inoculant to be added from the feed inlet, allowing them to fall onto the upper part of the molten iron under gravity. This feeding method results in the spheroidizing agent and inoculant contacting only the upper layer of the molten iron, while the contact efficiency between the lower layer and the spheroidizing agent and inoculant is low, leading to uneven contact between the molten iron and the spheroidizing agent and inoculant, thus affecting the spheroidizing efficiency. Therefore, this method does not meet the current requirements. To address this, we propose a new type of spheroidizing machine for ductile iron casting. Summary of the Invention

[0004] The purpose of this invention is to provide a novel spheroidizing machine for processing ductile iron castings, in order to solve the problem mentioned in the background art that the spheroidizing machine for ductile iron requires the spheroidizing agent and inoculant to be added from the feed inlet, so that the spheroidizing agent and inoculant fall onto the upper part of the molten iron under the action of gravity. This feeding method causes the spheroidizing agent and inoculant to contact the upper layer of the molten iron, while the contact efficiency between the lower layer of the molten iron and the spheroidizing agent and inoculant is low, resulting in uneven contact between the molten iron and the spheroidizing agent and inoculant, which in turn affects the spheroidizing efficiency.

The heat insulation platform 4 is equipped with a rotating shaft 8 through a bearing. The lower end of the rotating shaft 8 is fixedly installed with a hollow stirring shaft 15. The installation of the rotating shaft 8 and the hollow stirring shaft 15 allows the spheroidizing agent and inoculant to be directly discharged into the molten iron through the dispersion hole 20 on the outside of the hollow stirring shaft 15, so that the spheroidizing agent and inoculant are present in all layers of the molten iron, so that the spheroidizing agent and inoculant can mix with the molten iron more quickly and improve the spheroidizing efficiency of the device. The hollow stirring shaft 15 is provided with a dispersion hole 20 on the outside.

[0025] A support rod 16 is fixedly installed on the outside of the rotating shaft 8. A slide cylinder 17 is slidably installed on the outside of the support rod 16 through a slot. A scraper guide bracket 18 is fixedly installed on one end of the slide cylinder 17. The installation of the scraper guide bracket 18 and the slide cylinder 17 allows the scraper guide bracket 18 to play a turbulent role when the rotating shaft 8 rotates, thereby improving the mixing effect of the device. At the same time, the scraper guide bracket 18 can also scrape the inner wall of the spheroidizing box 13 to prevent material residue inside the device. A driven gear 9 is fixedly installed on the upper end of the outside of the rotating shaft 8. A motor bracket 5 is fixedly installed on one side of the upper end of the heat insulation platform 4. A drive gear shaft 6 is rotatably installed on the lower end of the motor bracket 5. The drive gear shaft 6 is meshed with the driven gear 9.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A feeding bracket 10 is installed at the upper end of the rotating shaft 8. The feeding bracket 10 is welded to the rotating shaft 8. A heat insulation layer 19 is fixedly installed on the inner side of the heating and heat preservation bracket 1. Installing the heat insulation layer 19 can enhance the heat preservation capacity of the device, prevent the molten iron from cooling, prevent a large amount of heat loss inside the device, and reduce the energy consumption of the device.

The drive motor 7 is connected to the drive gear shaft 6 through a coupling. A discharge pipe 12 is installed at the lower end of the spheroidizing box 13. The discharge pipe 12 is fixedly connected to the spheroidizing box 13. A support base 11 is installed at the lower end of the spheroidizing box 13.

[0027] Working Principle: During spheroidization, the operator adds the spheroidizing agent and inoculant to the rotating shaft 8 through the feed support 10. Then, the motor support 5 drives the drive gear shaft 6 to rotate, which in turn drives the rotating shaft 8 through the driven gear 9. Under the action of centrifugal force, the spheroidizing agent and inoculant inside the rotating shaft 8 are discharged into the molten iron through the dispersion hole 20 outside the hollow stirring shaft 15, allowing the spheroidizing agent and inoculant to mix rapidly with the molten iron. When the rotating shaft 8 rotates, it also drives the support rod 16, the slide cylinder 17, and the scraper guide bracket 18 to rotate, causing the support rod 16, slide cylinder 17, and scraper guide bracket 18 to turbulent the molten iron, improving the mixing effect of the molten iron with the spheroidizing agent and inoculant. The spheroidized material is discharged from the device, and the scraper guide bracket 18 can reach the inner wall of the spheroidizing tank 13. The residual material is scraped off to prevent waste. The device is equipped with a rotating shaft 8 and a hollow stirring shaft 15. The dispersion holes 20 on the outside of the hollow stirring shaft 15 can be used to directly discharge the spheroidizing agent and inoculant into the molten iron, so that the spheroidizing agent and inoculant are present on all layers of the molten iron. This allows the spheroidizing agent and inoculant to mix with the molten iron more quickly, improving the spheroidizing efficiency of the device. The scraper guide bracket 18 and the slide 17 can make the scraper guide bracket 18 play a turbulent role when the rotating shaft 8 rotates, improving the mixing effect of the device. At the same time, the scraper guide bracket 18 can also scrape the inner wall of the spheroidizing box 13 to prevent material from remaining inside the device. The heat insulation layer 19 can enhance the heat preservation capacity of the device, prevent the molten iron from cooling, prevent a large amount of heat loss inside the device, and reduce the energy consumption of the device.
