Device capable of selecting iron slag with high iron concentration from pile of iron slag

Abstract

The invention relates to the technical field of solid waste treatment and discloses a device capable of selecting iron slag with a high iron concentration from a pile of iron slag, which comprises anextraction device main body. A conveying belt relaxation device is fixedly mounted in the extraction device main body; the outer surface of the conveying belt relaxation device is connected with a conveying belt in a sliding manner; a straight gear is fixedly mounted at the top of the sliding block; the top of the straight gear is in engaged transmission with a cylindrical gear; and a bolt rod isfixedly installed on the back face of the cylindrical gear; a movable object block is in threaded transmission with the outer surface of the bolt rod; a threaded hole is formed in the right side of the movable object block; a U-shaped fixing groove is slidably connected to the bottom of the movable object block; and a baffle is fixedly installed on the outer surface of the movable object block. The cylindrical gear is meshed with the straight gear, and the sliding groove and sliding block mechanism at the bottom of the straight gear is matched, so that a shifting fork mechanism can shift the conveying belt back and forth, and the effect of relaxing the conveying belt is achieved.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment, in particular to a device capable of selecting iron slag with high iron concentration from a pile of iron slag. Background technique [0002] The treatment of solid waste usually refers to the solid and semi-solid waste materials generated in physical, chemical, biological, material, biochemical and other activities. Generally speaking, it is garbage. It mainly includes solid particles, garbage, slag, sludge, discarded products, damaged containers, defective products, etc. [0003] For the treatment of solid waste, compaction technology, crushing technology, solidification technology, incineration technology, etc. are generally used for processing. However, if the residue of iron products is disposed of directly, it is a waste of resources. Refining molten iron will cause greater waste, because the iron content in some iron product residues is very small, and it is not of much valu...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device that can select iron slag with high iron concentration from a pile of iron slag, which can selectively The advantage of obtaining part of the iron slag for secondary refining of molten iron solves the problem that the direct disposal of iron slag is not good for resources and the environment, and if it is directly used for refining without screening, it will cause greater waste of resources.
