Description

Technical Field

[0002] When processing metals, it is often necessary to remove rust on the metal surface. For example, after iron is oxidized, the oxidation of iron will cause a loose rust layer to form on its surface. This rust layer will change the original smooth and hard surface characteristics of the iron, making it rough and fragile. The presence of the rust layer will also increase the friction coefficient of the iron surface and reduce its mechanical properties, such as wear resistance and fatigue resistance. In addition, the oxidation of iron will weaken its internal structure, resulting in reduced strength and toughness. As the degree of oxidation deepens, the carrying capacity of the iron will gradually decrease, and may even cause fracture. The presence of the rust layer will also accelerate the corrosion process of the iron and further weaken its mechanical properties.

[0003] Therefore, when processing scrap metal, it is necessary to remove rust from the surface of iron products. However, before using hydrochloric acid to remove rust, you should ensure that the steel surface is clean and free of oil stains.

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Combine the following Figure 1-Figure 8 Describing the invention: The scrap metal processing device and the processing method thereof provided in the present embodiment include a ceramic processing cylinder 2 and a cleaning mechanism 3 and a rust removal mechanism 4 rotatably arranged on one side of the ceramic processing cylinder 2. Scrap metal is placed inside the ceramic processing cylinder 2. The cleaning mechanism 3 and the rust removal mechanism 4 both include a double-output shaft motor 301. The upper output end of the double-output shaft motor 301 is connected to an upper cover plate 302 through a first electric telescopic rod 305. The lower output end of the double-output shaft motor 301 is connected to a lower cover plate 303 through the first electric telescopic rod 305. The upper side of the upper cover plate 302 is connected to a spray box 306, and the spray box 306 is connected to a drain pipe 501. The lower side of the lower cover plate 303 is connected to a liquid storage tank 308. Sodium hydroxide solution or dilute hydrochloric acid solution is added to the liquid storage tank 308. The liquid storage tank 308 is connected to the liquid inlet pipe 502. When processing metal, it is often necessary to Remove rust from the metal surface. For example, after iron is oxidized, the oxidation of iron will cause a loose rust layer to form on its surface. This rust layer will change the original smooth and hard surface characteristics of the iron, making it rough and fragile. The presence of the rust layer will also increase the friction coefficient of the iron surface and reduce its mechanical properties, such as wear resistance and fatigue resistance. In addition, the oxidation of iron will weaken its internal structure, resulting in reduced strength and toughness. As the degree of oxidation deepens, the carrying capacity of iron will gradually decrease and may even cause fracture. The presence of the rust layer will also accelerate the corrosion process of iron and further weaken its mechanical properties. Therefore, when processing scrap metal, it is necessary to remove rust from the surface of iron products. However, before performing hydrochloric acid rust removal, ensure that the steel surface is clean and free of oil stains. If there is oil stain on the surface, degreasing should be carried out first, otherwise the hydrochloric acid rust removal effect will be uneven and incomplete.

[0026] In the present invention, a cleaning mechanism 3 and a rust removal mechanism 4 are simultaneously arranged on the ceramic processing cylinder 2. After the scrap metal is cleaned by the cleaning mechanism 3, the rust is removed by the rust removal mechanism 4. The structure is simple and the cleaning efficiency is improved.

[0027] For example, during the cleaning process, the dual-axis motor 301 is used to simultaneously rotate the upper cover plate 302 and the lower cover plate 303. When the dual-axis motor 301 is started, the upper cover plate 302 rotates to the top of the ceramic treatment barrel 2 and seals the upper port of the ceramic treatment barrel 2 through the first electric telescopic rod 305. The lower cover plate 303 rotates to the bottom of the ceramic treatment barrel 2 and seals the lower port of the ceramic treatment barrel 2 through the first electric telescopic rod 305. A high-pressure water pump 5 is fixedly arranged on one side of the first electric telescopic rod 305. The output end of the high-pressure water pump 5 passes through the upper cover plate 302 through the discharge pipe 501 and is connected to the upper part of the ceramic treatment barrel 2. The input end of the high-pressure water pump 5 passes through the lower cover plate 303 through the inlet pipe 502 and is connected to the bottom of the ceramic treatment barrel 2. The cleaning mechanism 3 or the rust removal mechanism 4 rotates around the dual-axis motor 301, and the rotation angle range of the cleaning mechanism 3 or the rust removal mechanism 4 is 0-120 degrees, which can prevent the cleaning mechanism 3 and the rust removal mechanism 4 from colliding during rotation, improve the efficiency of cleaning and rust removal, start the double-axis motor 301 on the cleaning mechanism 3, and rotate the upper cover plate 302 and the lower cover plate 303 to the upper and lower parts of the ceramic treatment tube 2, and then start the first electric telescopic rod 305 on the support arm 304, so that the upper cover plate 302 seals the upper port of the ceramic treatment tube 2, and the lower cover plate 303 seals the lower port of the ceramic treatment tube 2, and then start the high-pressure water pump 5 on the cleaning mechanism 3, extract the sodium hydroxide solution in the storage tank 308 through the liquid inlet pipe 502, and then discharge it to the upper cover plate 302 through the liquid discharge pipe 501, and rinse the scrap metal in the ceramic treatment tube 2 through the liquid permeable hole 307 on the upper cover plate 302, and the sodium hydroxide solution reacts with the fatty acids in the oil to generate water-soluble soap and glycerin. The specific steps are as follows: Start the double-output shaft motor 301 on the cleaning mechanism 3 to rotate the upper cover plate 302 and the lower cover plate 303 to the top and bottom of the ceramic treatment tube 2, and then start the first electric telescopic rod 305 on the support arm 304 to make the upper cover plate 302 seal the upper port of the ceramic treatment tube 2, and the lower cover plate 303 seal the lower port of the ceramic treatment tube 2, and then start the high-pressure water pump 5 on the cleaning mechanism 3, draw the sodium hydroxide solution in the liquid storage tank 308 through the liquid inlet pipe 502 and then discharge it to the upper cover plate 302 through the liquid discharge pipe 501, and rinse the scrap metal in the ceramic treatment tube 2 through the liquid permeable hole 307 on the upper cover plate 302, the sodium hydroxide solution reacts with the fatty acid in the oil to generate water-soluble soap and glycerin, so that the oil on the surface of the scrap metal can be removed, thereby improving the cleaning efficiency and cleaning effect.

[0028] In the rust removal process, the double-output shaft motor 301 on the rust removal mechanism 4 uses the same method as above to make the upper cover plate 302 seal the upper port of the ceramic treatment tube 2, and the lower cover plate 303 seal the lower port of the ceramic treatment tube 2, and then start the high-pressure water pump 5 on the rust removal mechanism 4, extract the dilute hydrochloric acid solution in the liquid storage tank 308 through the liquid inlet pipe 502 and then discharge it to the upper cover plate 302 through the liquid discharge pipe 501, and acidify and corrode the scrap metal in the ceramic treatment tube 2 through the liquid permeable hole 307 on the upper cover plate 302, so as to remove the rust on the surface of the scrap metal. The specific steps are as follows: The double-output shaft motor 301 on the rust removal mechanism 4 rotates the upper cover plate 302 and the lower cover plate 303 to the top and bottom of the ceramic treatment cylinder 2, and then starts the first electric telescopic rod 305 on the support arm 304, so that the upper cover plate 302 seals the upper port of the ceramic treatment cylinder 2, and the lower cover plate 303 seals the lower port of the ceramic treatment cylinder 2. Then, the high-pressure water pump 5 on the rust removal mechanism 4 draws the dilute hydrochloric acid solution inside the liquid storage tank 308 through the liquid inlet pipe 502 and then discharges it to the upper cover plate 302 through the liquid discharge pipe 501, and acid-corrodes the scrap metal inside the ceramic treatment cylinder 2 through the liquid permeable hole 307 on the upper cover plate 302, so as to achieve the purpose of rust removal and improve the efficiency of rust removal and the cleaning effect.

[0029] Therefore, the oil stains on the surface of the scrap metal can be removed by the cleaning mechanism 3, and after the oil stains are treated, the metal is derusted by the rust removal mechanism 4, which has a simple structure and improves the efficiency of rust removal.

In addition, the rubber sealing ring inside the liquid accumulation groove 309 can increase the friction between the liquid accumulation groove 309 and the ceramic treatment tube 2, thereby improving the ceramic treatment tube 2. To ensure the sealing of the ceramic treatment tube 2, the output end of the double-output shaft motor 301 is connected to the support arm 304, and the first electric telescopic rod 305 is fixedly arranged on the support arm 304. The output end of the first electric telescopic rod 305 is fixedly connected to the upper side of the upper cover plate 302 or the lower side of the lower cover plate 303.

The filter screen 9 is slidably provided inside the ceramic processing cylinder 2, and the waste metal can be placed directly on the filter screen 9, which is convenient for cleaning and rust removal together, and at the same time, it is convenient to remove the filter screen 9 from the ceramic processing cylinder 2, which is convenient for cleaning the filter screen 9 later, thereby improving the convenience of use. Of course, if the filter screen 9 is not used, the waste metal can also be placed directly on the lower cover plate 303 and placed inside the cleaning mechanism 3 together, thereby improving the flexibility and scope of use.

After the second electric telescopic rod 7 is started, the filter screen 9 inside the ceramic processing cylinder 2 is pushed upward, thereby achieving the purpose of collecting scrap metal and facilitating the later processing of scrap metal.
