Description

Technical Field

[0001] The utility model relates to the field of spheroidizing agent processing equipment, in particular to spheroidizing agent production equipment which can effectively reduce the oxidation rate of magnesium. Background Art

[0002] Spheroidizer is an additive used to obtain spheroidal graphite cast iron. In the process of cast iron smelting, the addition of spheroidizer can make the graphite in the cast iron crystallize into spheres, thereby improving the strength, toughness and wear resistance of the cast iron. The main components of the spheroidizer are spheroidizing elements, such as magnesium, rare earth elements (such as cerium and yttrium) and calcium. Among them, magnesium is the strongest spheroidizer, but because of its low boiling point and easy vaporization, silicon-iron-magnesium alloy or rare earth silicon-iron-magnesium alloy is often used as a spheroidizer in industry. Cerium among the rare earth elements has a high spheroidizing ability, but it is expensive and is usually used to produce large-section ductile iron castings. Heavy rare earth elements, such as yttrium-based heavy rare earths, have better anti-degradation ability. Although calcium has a weaker spheroidizing ability, it acts smoothly and is sometimes used in the spheroidizing process. In the process of spheroidizing agent production, special production equipment is usually required.

[0003] In the existing production process of spheroidizers, it is usually necessary to mix the spheroidizers. Usually, a mixer is used. A gas supply tank for storing inert gas is usually set on one side of the mixer. The gas is usually argon or nitrogen. In the specific use process, the spheroidizer raw materials are mixed by the stirring shaft and stirring blades in the mixer, and the inert gas is transported to the inside of the mixer through the gas supply tank. By adding inert gas, the oxygen content in the mixer can be effectively reduced, thereby slowing down or preventing the oxidation process of magnesium. However, in the existing mixing process, the raw materials may clump and precipitate due to humidity and adhesion. The stirring blades cannot break up and mix the clumps of raw materials that have settled to the bottom, which will affect the stirring effect and cause uneven mixing of the raw materials.

[0004] Therefore, it is necessary to provide a new spheroidizing agent production equipment that can effectively reduce the magnesium oxidation rate to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a spheroidizing agent production equipment which can effectively reduce the oxidation rate of magnesium.

[0006] The utility model provides a spheroidizing agent production device that can effectively reduce the oxidation rate of magnesium, comprising an air supply device and a mixing production body arranged on one side of the air supply device, wherein a stirring device is arranged inside the mixing production body;

[0007] The stirring device includes a driving member, a stirring rod and four fixed plates. The output end of the driving member is fixedly connected to the upper end of the stirring rod. The outer wall of the stirring rod is evenly fixedly connected with multiple connecting rods. The multiple connecting rods are all arranged to be inclined downward. The ends of the multiple connecting rods away from the stirring rod are fixedly connected with stirring blades. The multiple stirring blades are all arranged in a spiral shape. The outer wall of the stirring rod away from the multiple connecting rods is evenly fixedly connected with four fixed plates. The cross-sections of the four fixed plates are all arranged in a triangular shape. The bottom ends of the four fixed plates are all in contact with the inner bottom wall of the mixed production body. Scraping components are also arranged on the opposite sides of the stirring rod. The opposite sides of the two scraping components are in contact with the inner wall of the mixed production body.

[0008] Preferably, the gas supply device includes a gas supply tank, a valve and a connecting pipe, the valve is arranged at the bottom of the gas supply tank, the side of the valve away from the gas supply tank is fixedly connected to one end of the connecting pipe, and the end of the connecting pipe away from the valve is connected to the interior of the mixed production body.

[0009] Preferably, the driving member is a motor, and the motor is fixedly arranged at the upper end of the mixing production body, and the output end of the motor is fixedly connected to the upper end of the stirring rod.

[0010] Preferably, the bottom end of the mixing production body is fixedly connected to a base.

[0011] Preferably, the bottom end of the gas supply tank is fixedly connected to two support frames, one of the support frames is fixedly connected to a fixing block, and one end of the connecting pipe is fixedly passed through the fixing block.

[0012] Preferably, the scraping assembly includes a transverse plate and a scraper, and two transverse plates are provided. One end of the two transverse plates is fixedly connected to one side of the stirring rod, and one end of the two transverse plates away from the stirring rod is fixedly connected to one side of the scraper, and the scraper is in contact with the inner wall of the mixing production body relative to one side of the two transverse plates.

[0013] Preferably, a discharge pipe is also provided at the bottom end of the mixing production body.

[0014] Compared with the related art, the spheroidizing agent production equipment provided by the utility model which can effectively reduce the magnesium oxidation rate has the following beneficial effects:

[0015] 1. The device is provided with four fixed plates, and the four fixed plates are evenly fixed on the outer wall of the stirring rod, and the bottom ends of the four fixed plates are in contact with the inner bottom wall of the mixing production body. When the spheroidizing agent raw materials clump and sink to the bottom, the four fixed plates are provided to prevent the clumped raw materials from adhering to the bottom of the mixing production body, thereby reducing the loss of raw materials, so that the clumped raw materials that sink to the bottom can be broken up again by the stirring blades, thereby improving the overall mixing production effect to a certain extent.

[0016] 2. Since the connecting rod and the stirring blades are both tilted downward, and the stirring blades are spirally arranged, the spiral stirring blades can generate shear force, which is helpful for the refinement and dispersion of the material during the stirring process. When the stirring blades are tilted downward, the downward-tilted stirring blades will generate a downward driving force when rotating. This driving force helps to move the material from the top to the bottom of the stirring tank, thereby realizing the circulation of the material and improving the overall mixing effect.

[0026] The stirring device includes a driving member, a stirring rod 10 and four fixed plates 11. The output end of the driving member is fixedly connected to the upper end of the stirring rod 10. The outer wall of the stirring rod 10 is evenly fixedly connected with multiple connecting rods 15. The multiple connecting rods 15 are all arranged to be inclined downward. The ends of the multiple connecting rods 15 away from the stirring rod 10 are fixedly connected with stirring blades 13. The multiple stirring blades 13 are all arranged in a spiral shape. The outer wall of the stirring rod 10 away from the multiple connecting rods 15 is evenly fixedly connected with four fixed plates 11. The cross-sections of the four fixed plates 11 are all arranged in a triangular shape. The bottom ends of the four fixed plates 11 are all fitted with the inner bottom wall of the mixed production body 1. Scraping components are also provided on the opposite sides of the stirring rod 10. The opposite sides of the two scraping components are all fitted with the inner wall of the mixed production body 1. The driving member is a motor 4. The motor 4 is fixedly arranged at the upper end of the mixed production body 1. The output end of the motor 4 is fixedly connected to the upper end of the stirring rod 10.

[0027] The gas supply device includes a gas supply tank 2, a valve 9 and a connecting pipe 3. The valve 9 is arranged at the bottom of the gas supply tank 2.
