The problem of rate.
To achieve the above object, the invention provides the following technical scheme: a kind of recycling of waste plastics system, operation
Steps are as follows:
A, waste plastic crushes: waste plastic after the recovery being put into the particle for being crushed to 3-5cm in pulverizer, particle is put into
It carries out disinfection in the thimerosal that concentration is 0.01% in disinfect box, it is 1/20 that plastic grain and thimerosal, which are put into ratio, repeatedly clearly
8-10 times is washed to clean by clear water to plastic grain being dried after clean；
B, pre-process: plastic grain, calcium oxide, benzene, dimethylbenzene after dry are put into Twin screw extruder after mixing, are squeezed
Machine discharge port is heated out；
C, it decomposes: being uniformly laid with the river sand of one layer of 50 mesh or so in decomposing pot bottom, sand layer thickness 5-10cm then will pretreatment
Mixture and powdered carbon afterwards, copper powder, iron powder etc. are added in decomposing pot together, and the ratio that is put into is 5:5:2:3, then to decomposing pot into
Row heating, is heated waste plastic using volume reduction machine after decomposition, is squeezed and air-cooled, finally received using collecting bin
Collection utilizes.
Preferably, the pulverizer in step is plastics jaw crusher, and discharging-material size is 6~14mm, production capacity
For 300~800kg/h, the sodium hydroxide ethanol solution of 10~20wt% and the hydrogen peroxide of 3~8wt% are filled in the disinfect box
Solution.
Preferably, the material rate being put into the Twin screw extruder in stepb is 1:15:5:8, and double helix squeezes
Out-of-machine temperature is controlled at 220-260 °C, and control heating temperature is identical as Twin screw extruder temperature.
Preferably, the decomposing pot computer heating control temperature in step C is 350-400 °C, and volume reduction machine is single screw rod modeling
Expect volume reduction machine, production capacity is 600~1000kg/h, and heating temperature is 1800~220 °C.
Compared with prior art, beneficial effects of the present invention are as follows:
1, the present invention, can be to preliminary smashed by increasing decomposing pot in the technique for carrying out recycling processing to waste plastic
Plastic grain solid is heated, and prevents from occurring in following process bulky grain plastic grain and equipment is caused to block or failure,
Waste plastic can be heated, be squeezed and air-cooled using volume reduction machine simultaneously, it can waste plastic be made profits again to treated
With protecting environment that can also economize on resources.
