Description

Technical Field

[0001] The utility model relates to the technical field of steel recycling, in particular to a crushing device for recycling and processing waste steel. Background Art

[0002] Scrap steel refers to the steel waste (such as trimmings, cuttings, etc.) that does not become products during the production process of steel mills, as well as the steel materials in equipment and components that are scrapped after use. Scrap steel is steel, and scrap iron is pig iron. They are collectively called scrap steel. The total amount of scrap steel produced in the world each year is 300 to 400 million tons, accounting for about 45 to 50% of the total steel production. Among them, 85 to 90% is used as steelmaking raw materials, and 10 to 15% is used for casting, ironmaking and recycled steel. The scrap steel produced in the production process of steel mills is called "returned scrap steel", "self-produced scrap steel" or "circulated scrap steel". Its carbon content is generally less than 2.0%, and the sulfur and phosphorus contents are not more than 0.05%. Scrap steel has various shapes due to different production conditions. Its performance is basically the same as the finished product from which it is produced, but it is also affected by factors such as aging effectiveness and fatigue, and its performance is reduced. The self-produced scrap steel of ordinary steel mills accounts for about 15 to 25% of the steel production; special steel mills reach 30 to 50%. Scrap steel is mainly produced in steelmaking workshops, steel casting workshops and steel cold processing and hot processing workshops.

[0003] The application number is CN202222584011.1, which discloses the technical field of scrap steel crushing, and in particular relates to a crushing device for recycling and processing scrap steel, comprising a frame, an inner wall of the frame is connected to a recycling box, the top of the frame is fixedly connected to a load-bearing block, the center of the inner wall of the load-bearing block is provided with a through hole, and the top of the load-bearing block is fixedly connected to a box shell. In the utility model, by arranging a box door, dust can be blocked, and by arranging a dust collector, the dust generated by the crushing device can be processed, thereby preventing the dust from floating out of the device, and by arranging a filter cartridge, all excess safety gas can be discharged, thereby improving the working efficiency of the vacuum cleaner, and by arranging a crushing box, it can not only play the role of loading scrap steel, but also play the role of blocking the top of the crushing device, so that the inside of the device can be more closed, thereby preventing scrap steel fragments from flying out of the device, thereby effectively solving the problems and shortcomings of the existing device.

[0004] Although the above-mentioned utility model can block dust by setting a box door, and can process the dust generated by the crushing device by setting a vacuum cleaner, thereby preventing the dust from floating out of the device, and can discharge all excess safety gas by setting a filter cartridge, thereby improving the working efficiency of the vacuum cleaner, and by setting a crushing box, it can not only play the role of loading scrap steel, but also play the role of blocking the top of the crushing device, so that the inside of the device can be more closed, thereby preventing scrap steel fragments from flying out of the device, thereby effectively solving the problems and shortcomings of the existing device, but there is a shortcoming that when the device is used, it is more difficult to crush larger scrap steel plates, and when steel of different sizes is crushed, it is very easy to damage the parts of the crushing assembly, which shortens the service life of the device to a certain extent.
