Iron screening device for engineering

Abstract

The invention relates to an iron screening device for engineering and belongs to the field of environmental protection recycling equipment. A feeding device is installed on the left side of the upperend of a first support, and the position of the feeding device is located on the right side of the top end of a conveying device; a separation device is installed on the left side of the lower end ofthe first support, and the position of the separation device is located at the position, close to the front, below the feeding device; a function selecting device is installed at the lower end of a discharging port; and the conveying device is fixed to a second support and the feeding device. According to the iron screening device for the engineering, due to cooperation of a roller and an electromagnet, iron substances in materials are thrown into a steel and iron storing box, impurities are repeatedly screened through the function selecting device, the recycling rate is increased, the function of recycling the iron substances and precious metal attached to the iron substances is achieved, and not only is the environment protected, but also great economic benefits can be created.

Description

technical field [0001] The invention relates to an engineering iron sieving device, specifically a device that sends materials mixed with iron to a feed port through a conveyor belt, and screens and separates iron from the materials through a sorting device, which belongs to environmental protection recycling equipment field. Background technique [0002] At present, my country's garbage recycling mechanism is still immature, and a large number of discarded vehicles, mechanical equipment and electronic products are generally stored in the open air. After a long period of exposure to the sun and wind, a large number of iron and metal pieces on these waste products fell off and mixed with the soil under the storage area. At this stage, my country only recycles the metals stored above the soil, while ignoring the considerable amount of iron mixed in the soil. [0003] This behavior of ignoring the mixed iron in the soil and not recycling it is a huge waste of metal resources,...

Problems solved by technology

[0003] This behavior of ignoring the mixed iron in the soil and not recycling it is a huge waste of metal resources, and the discarded circuit boards contain a lot of heavy metals, which will fall off in the soil along with the iron. Recycling will cause irreversible damage to the environment
