Description

A kind of abandoned car disassembles recycling technique

Technical field

The present invention relates to the recovery and utilization technology field of waste and old product process and resource, specifically belong to a kind of abandoned car and disassemble recycling technique.

Background technology

Along with the development of automotive technology and the raising of people's living standard, the consumption of automobile is increasing, meanwhile, also have a large amount of automobiles to be scrapped every year, a lot of parts cannot re-use, the huge negative effect to environment band.Abandoned car is formed primarily of materials such as iron and steel, non-metals, plastics, rubber, glass.Domestic at present to the processing method of abandoned car be adopt to disassemble by hand, artificial separation, namely first with gas flame cuttiug, car body is split, then manually carries out material selection, reclaim iron and steel, copper aluminium, other non-metals, plastics, glass etc.This manual work mode all can realize the automobile cracking and sorting action to disassembling, but treatment effeciency is low, and labour intensity is large, and produces environmental pollution, does not meet the demand for development of modern automobile industry and social life.

Summary of the invention

For the problems referred to above, the object of this invention is to provide a kind of abandoned car and disassemble recycling technique, there is provided a kind of do mechanization operation efficiency high, without secondary environmental pollution, greatly alleviate labor strength, realize the fast-crushing of abandoned car vehicle body and physical separation sorting, make the technological process that the material such as iron and steel, copper, aluminium, rubber contained in vehicle body is recycled.

The technical solution used in the present invention is as follows:

A kind of abandoned car disassembles recycling technique, it is characterized in that, comprises the following steps:

1) preprocessing station: fluid reclaims (machine oil, gasoline, dichlorodifluromethane, anti-freezer); Storage battery, tire recycling, put into booty and greasy dirt in lube purification system, carry out cycle for the treatment of recycling, and the on-the-spot rubbish produced of process will transfer out by arranging rubbish load-transfer device at conveyor line carrier bar tail end;

2) disassemble: abandoned car parts are disassembled, select the parts being rich in rare precious metal; It comprises front and back cover, car door, vehicle window, rain brush, elevator; Before and after headlight, bumper/spoiler, seat, ceiling, glue, safety belt, bearing circle; Console, full vehicle wire harness, Wiper motor, air-conditioning wind-collecting cover; Machinery space inside (1. water tank, refrigerant fluid 2. air-conditioner evaporation tank, condenser 3. fluid reservoir, water tank expansion kettle 4. master cylinder, vacuum pump 5. blowing engine, igniting high voltage package etc.); Pretreatment, ingot beam, freeing pipe bottom front-rear axle; Front-rear axle top pretreatment, steering wheel; Driving engine, change speed gear box are separated; Vehicle body overall separation;

3) mechanization, automatic business processing by the cracking and sorting process implementation of vehicle body, the mode of two-stage fragmentation is utilized progressively auto body to be crushed to preliminary dimension, be convenient to follow-up material reclaim respectively, the material composition according to abandoned car vehicle body in sorting flow process adopts negative pressure-cyclonic separation flow process, magnetic separating flow process, eddy current separation flow process and cylinder sieving circuit targetedly in order respectively by the light materials after vehicle body fragmentation, magnetic metal, non-metals, micro mist material, glass, rubber and plastics separation and recovery;

4) by 2) and 3) the junked-auto parts containing rare precious metal disassembled are broken, then grind, whole mistake 130 ~ 150 mesh sieve; Then add water stirring and dissolving, then puts it into heavy metal wastewater thereby and enter regulating reservoir, carries out the adjustment of the water yield and the homogenizing of water quality; Regulating reservoir waste water is after lift pump promotes, enter Nanoscale Iron reaction unit, Nanoscale Iron is added by 2.5 times of heavy metal ions in wastewater total content, abundant stirring, make the rare precious metal in Nanoscale Iron and waste water and other heavy metals carry out being oxidized, reduce, adsorb, coprecipitated reaction, abundant reaction 30 ~ 35 minutes, and stir continuously; Add coagulant and carry out catalytic oxidation coupling flocculation reaction, and precipitate and separate; Precipitation water outlet enters filter, removes suspended matter and heavy metal ion further, then enters discharge bay; What sewage treatment system produced drains into body refuse pond containing rare precious metal body refuse, enters sludge concentrating pot and concentrate further after promoting, and the body refuse containing rare precious metal after concentrated is recycled after press filter dehydration.

Compared with the prior art, beneficial effect of the present invention is as follows:

Do mechanization operation efficiency of the present invention is high, without secondary environmental pollution, greatly alleviate labor strength, realize the fast-crushing of abandoned car vehicle body and physical separation sorting, makes the technological process that the material such as iron and steel, copper, aluminium, rubber contained in vehicle body is recycled.
