Waste metal recovery device

Abstract

The invention provides a waste metal recovery device. The waste metal recovery device comprises a pretreatment unit, a screening unit and a crushing unit; the discharging end of the pretreatment unit faces the screening unit, and the screening unit communicates with the crushing unit. According to the waste metal recovery device, the arranged pretreatment unit is used for carrying out surface cleaning and decontamination treatment on waste metal; the waste metal is subjected to drying protection through drying treatment, and oxide is prevented from being generated again; then iron metal and non-iron metal are distinguished through the arranged screening unit, and the screening unit communicates with corresponding conveying channels s to carry out classification operation and crushing operation on the waste metal; with adoption of the technical scheme, the technical problems that many impurities exist in the waste metal and are difficult to recover effectively are solved; a water storage tank is divided into a plurality of cleaning pools through arranged material separation units, workpieces are conveyed in a rotating mode, and the workpieces are cleaned repeatedly while independent operation between the cleaning pools is guaranteed.

Description

technical field [0001] The invention relates to the technical field of environmental treatment, in particular to a scrap metal recovery device. Background technique [0002] Metal recycling refers to the separation of swimming substances from scrap metals into recycled products through physical or mechanical processing. It is an industrial chain from recycling, dismantling, and recycling. The metal recycling industry has formed a complete industrial chain and recycling ecosystem. [0003] Traditional heavy factories usually recycle large pieces of scrap metal, but for small-volume scrap metal such as metal shavings, they are directly treated as garbage, resulting in waste of metal regeneration resources, and cutting metal objects increases the difficulty of environmental governance. Some metal recycling mainly uses rolling units to flatten and then transport operations, but the existing old metals are stored in a messy manner, with stains or harmful substances attached to t...

Problems solved by technology

[0003] Traditional heavy factories usually recycle large pieces of scrap metal, but for small-volume scrap metal such as metal shavings, they are directly treated as garbage, resulting in waste of metal regeneration resources, and cutting metal objects increases the difficulty of environmental governance. Some metal recycling mainly uses rolling units to flatten and then transport operations, but the existing old metals are stored in a messy manner, with stains or harmful substances attached to the surface, and harmful substances may have a corrosion effect on the old metals, thus Affects the recycling of old metals

[0004] For this reason, existing scrap metals with impurities on the surface are mainly cleaned by vibration, but only impurities with small particles and low adhesion can be cleaned, and it is difficult to achieve effective cleaning operations.
