Prior art is to thing light on the sieve in rubbish sorting in addition again, plastic paper is wherein sorted out, add a certain amount of wooden thing again to make the technique that wood moulds plate and have existence, but its shortcoming is, sorting amount is large, cost is high, and the leftover materials consumed after wood materials, sorting also need reprocessing or burning or return landfill yard.
See Fig. 1, the source of the upper light thing of sieve is described in figure, details can with reference to another patent of invention published of the present inventor, and it is called a kind of disposal of human lives's rubbish and the method for recycling, and application number is 201410025679.X (publication number CN103934251).
Summary of the invention
In order to solve the problem, the invention provides a kind of method of relative ease and the lower-cost derivative recycling to the separating domestic garbage process that the upper light thing of sieve processes.
To achieve these goals, the present invention adopts following technical scheme:
The technique of the derivative recycling of one way of life garbage sorting process, adopts following steps:
S1, forced feed: the feeding that upper for sieve light thing has been come comminutor by forced feed;
S2, granulation: carry out granulation by comminutor, and collection process is carried out to the waste gas produced in granulation process and steam;
S3, cooling crush: the particle adopting pulverizer to be made by comminutor is pulverized, then through air blast quenching;
S4, mix and blend: in semi-finished product in step s3, add pigment, sufficient mix and blend;
S5, extrusion molding: the semi-finished product in step S4 are shaping by extruder, namely need to open the discharge end that different moulds is placed in extruder according to differential profiles, by high temperature, the high pressure final molding of extruder, then shaped article cooling water is cooled.
Preferably, in step S1, on described sieve, light thing comprises and moulds paper, waste paper, rubber and fine cloth.
Preferably, in step S1, on described sieve, light thing is through cleaning, and by moisture content squeezing more than secondary, moisture content is less than 30%.
Preferably, in step S1, on described sieve, light thing is the soft material that premenstrual road shredder fully tears up, and material length is less than 8mm.
Preferably, in step S2, described discarded and steam is by discharging after charcoal absorption.
Preferably, in step S5, cooling water circulation uses.
Preferably, in step S5, shaped article is sheet material or bar.
