Embodiment

[0017] The process is as follows:

[0018] Cleaning: cleaning up iron wires, nuts and other sundries, cutting wires, and metal waste wires detected by metal detectors;

[0019] Crushing: put the above-mentioned waste silk into the crusher for crushing, and set the rollers at the entrance of the crusher to control the feeding amount, and form short fibers and powders of 5mm after crushing;

[0020] Rinse: wash the above-mentioned broken waste silk with the water treated by the sewage treatment station, wash away the wetting agent attached to the waste silk, and the washed waste silk is initially separated from the water by the sand-water separator, and rinsed The final water is sent back to the sewage station for treatment;

[0021] Drying; the above-mentioned waste silk after washing is sent to the dryer using the waste hot air of the kiln for continuous drying by the frequency conversion speed regulating hoist; the water content of the dried fiber is controlled to be less th...

Abstract

The invention relates to a recovery processing technology for metal wastes, which mainly comprises steps of arranging and picking, crushing, washing, drying and transporting. The recovery processing for the metal wastes is low in cost, simple in procedure and high in reuse frequency. According to the ingredients of waste wires, the use of the waste wires, by the adoption of different use ways, can bring about a certain economic benefit and reduce social public hazard and pollution.

Description

technical field [0001] The invention relates to a waste recycling process, in particular to a metal waste recycling process. Background technique [0002] Metal waste is mostly produced in production and construction, daily life and other social activities, and basically or completely loses its use value within a certain time and space. It mainly includes waste residue discharged from industrial and urban construction projects. There are many classifications: according to the shape, it can be divided into granular waste, powdery waste and massive waste. The pollution to the environment is mainly manifested in: ①Polluted water bodies, such as entering the surface water bodies with surface runoff, seepage water from garbage and waste residues enters the ground water bodies through the soil, fine particle solid waste flutters with the wind and falls into the ground water bodies, and dumps the waste directly into lakes, rivers and seas etc. ② Pollution of the atmosphere, such...
