Description

Technical Field

[0001] The utility model relates to the technical field of solid waste recycling equipment, in particular to a scrap metal recycling device for solid waste. Background Art

[0002] Solid waste refers to solid and semi-solid waste materials generated by human production, consumption, life and other activities, commonly known as "garbage". Solid waste is divided into domestic waste, construction solid waste and agricultural solid waste. Construction solid waste contains some metallic iron, which can be recycled through recycling equipment to avoid waste of resources.

[0003] The prior art CN212263506U proposes a solid waste recycling and processing device, including a base plate, a coarse crushing mechanism is installed on the upper end of the base plate through a support frame, the upper end of the coarse crushing mechanism is provided with an opening, the lower end of the coarse crushing mechanism is open, and a reduction motor is fixedly installed on the support frame. The device recycles metallic iron by crushing the solid waste.

[0004] However, the device still has certain defects in actual application. In the process of treating construction solid waste, since the solid waste contains metal, the waste is crushed by a rotating blade, which can easily cause damage to the blade. At the same time, when encountering materials such as iron wire, it will be entangled on the blade shaft. At the same time, some solid waste contains metal and some does not, and the existing technology does not distinguish between them, so that all waste is processed together during crushing. This method is inefficient and will waste more energy to crush solid waste that does not contain metallic iron, which makes it have certain defects in application. For this reason, we have developed a waste metal recovery device for solid waste to overcome the defects of the existing technology. Utility Model Content
