Abstract
The invention discloses the process for separating and recovering metal and plastic compounds, which is designed for solving the problems of high cost and low recovery rate of the conventional recovery process. The method comprises the following steps of: crushing, namely crushing the metal and plastic compounds into particles; grinding and decomposing, namely grinding the particles into a metal and plastic mixture; electrically separating, namely electrically separating the metal and plastic mixture into metal and plastics; and extruding, namely extruding the obtained plastics in the electric separation step to prepare a finished product. The process is high in recycling rate, does not need heating, burning and chemical raw materials, and does not waste resources by recycling all the water. In the process, related steps are completed mechanically or electrically, and the process has no environmental pollution and less investment and is suitable for large-scale promotion.

Summary of the invention
The purpose of this invention is to provide a kind of metal and plastic composite process for separating and recovering, this technology need not heat, and burns and industrial chemicals, and water circulation use does not cause any environmental pollution, and cost is low, and efficient height, day output can reach tons up to a hundred.
For achieving the above object, the present invention adopts following technical scheme: it comprises the steps:
Fragmentation is broken into particulate material with metal and plastic composite;
Abrasive dust decomposes wears into metal and plastic hybrid with described particulate material;
Electric separation is with described metal and plastic hybrid, and electric separation is separated into metal and plastics;
Extrude the plastics that obtained in the described step electric separation are extruded, make finished product.
Further, before the described step electric separation, also comprise the steps:
Gather materials described metal and plastic hybrid, selection by winnowing is a granularity greater than 80 orders and the granularity mixture less than two kinds of grades of 80 orders; And granularity sifted out greater than the plastic foil in the 80 order mixtures.
In the described step fragmentation, adopt disintegrating machine that metal and plastic composite are broken into particulate material less than 12mm.
Described step abrasive dust adopts one or more abrasive dust disassembler that metal and plastic composite are worn into metal and the plastic hybrid of granularity less than 2.5mm in decomposing.
During described step is gathered materials, adopt loading head collect respectively granularity greater than 80 purpose mixtures and granularity less than 80 purpose mixtures.
In the described step electric separation, adopt electrostatic separator that metal and plastic hybrid are carried out electric separation and separate.
During described step is extruded, adopt one or more extruder that plastics are extruded, make finished product.
Metal provided by the invention and plastic composite process for separating and recovering by fragmentation, abrasive dust, electric separation and operation such as extrude, are separated into metal and plastics with metal and plastic composite, realize the recycling of metal and plastic composite; Compared with prior art, technology of the present invention finally obtains metal and plastics, and the recovery utilization rate height need not heat, burning and industrial chemicals, and water is all recycling, does not waste resource; In the technical process of the present invention, all finish the work of correlation step, do not pollute the environment, invest for a short time, be suitable for large-scale promotion with machinery or electric power.
Description of drawings
Fig. 1 is the process chart of metal of the present invention and plastic composite process for separating and recovering.
The specific embodiment
In order to make those skilled in the art person understand technical scheme of the present invention better, and above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with drawings and Examples.
Metal provided by the invention and plastic composite process for separating and recovering comprise the steps:
Broken one or more disintegrating machine that adopts of S101 carries out fragmentation to metal and plastic composite, obtains the particulate material of granularity less than 12mm;
The S102 abrasive dust decomposes employing abrasive dust disassembler described granularity is carried out the abrasive dust decomposition less than the particulate material of 12mm, obtains metal and the plastic hybrid of granularity less than 2.5mm;
S103 gathers materials the mixture of described granularity less than 2.5mm, selection by winnowing is a granularity greater than 80 orders and the granularity mixture less than two kinds of grades of 80 orders, adopt two loading heads collect respectively granularity greater than 80 purpose mixtures and granularity less than 80 purpose materials, wherein, granularity all is plastics less than 80 purpose materials; And adopt vibratory sieve that plastic foil or the fibrous matter that contains in the coarsegrain material sifted out, if do not contain plastic foil and fibre object can be removed this vibration screening program from.If decompose metal and the plastic hybrid that obtains through the S102 abrasive dust, granularity then can replace loading head with other dust arrester installation all less than 80 orders.
Many electrostatic separators of S104 electric separation employing carry out electric separation to described metal and plastic hybrid successively to be separated, and obtains metal and plastics;
S105 extrudes and adopts many extruders, and the granularity that is obtained during S103 is gathered materials is extruded less than the plastics that obtain in 80 purpose plastics and the S104 electric separation, makes plastic product.
As shown in Figure 1, the concrete course of work of the present invention is as follows:
With metal and plastic composite through disintegrating machine 1 fragmentation, disintegrating machine 1 can be selected 750 types for use, can be made as many, metal and plastic composite can be broken into the granularity below the 12mm, every disintegrating machine 1 discharging opening is provided with an elevator 2, and storage bin 3 upper ends are provided with sub-material equipment, sub-material equipment scatter broken material in storage warehouse 3, can control the work of disintegrating machine 1 and elevator 2 by material device in the storage warehouse 3, storage warehouse 3 lower end discharging openings are provided with baffle plate, can regulate blanking.The discharging opening of broken material storage warehouse 3 is connected with the charging aperture of automatic feeder 4, and automatic feeder 4 is sent broken material into abrasive dust disassembler 5.
Through vibratory sieve 8 screenings, plastic foil that sifts out or fibre object 9 export from its upper end directly advances extruder 17 to granularity greater than 80 purpose mixed materials, if material does not contain plastic foil or fibre object can be removed this vibration screening program from; Metal and plastic hybrid enter through elevator 10 from the outlet of vibratory sieve lower end and decompose material storage warehouse 11, enter each electrostatic separator 13 simultaneously by each automatic feeder 12, isolate metal and plastics; Wherein, plastics are collected by feeder 14, advance plastics storage warehouse 16 through elevator 15, and this plastics storage warehouse 16 can be according to the quantity of how much fixing port of extruder under the storehouse 17; Plastics are made finished product by extruder 17.
