Abstract
The invention discloses a waste plastic recycling, screening and pelleting device, and belongs to the technical field of reprocessed plastics. The waste plastic recycling, screening and pelleting device comprises a separating device, a conveying device and a reaction still. The reaction still comprises a still body, a heating pipe, a feeding bin, a top cover, a stirrer, a metal net, a first metalpull rope, a second metal pull rope, a first winding machine, a second winding machine, a valve, a metal material outlet, a still body support, a stirring motor and two weight measuring scales. Due tothe fact that certain metal objects exist in waste plastics possibly, the overall weight of the reaction still is monitored in real time through the two weight measuring scales; when the weight is too high, the first winding machine and the second winding machine work, the metal net is raised through the first metal pull rope and the second metal pull rope, the stretching height of the first metal pull rope is larger than that of the second metal pull rope, and at this moment, an inclined face is formed by the metal net; and the metal objects are discharged out of a metal discharging port, and the technical problem that when the waste plastics are subjected to a pelleting procedure in the prior art, the metal objects are doped is avoided.
Description
technical field [0001] The invention relates to the technical field of recycled plastics, in particular to a recycling, screening and granulating device for waste plastics. Background technique [0002] With its light weight, high strength, corrosion resistance, easy processing and other excellent properties, plastics play an important role in various fields of economic construction. However, with the wide application of plastics, the disposal of waste plastics has become a difficult problem. On the one hand, waste plastics will It causes environmental pollution and wastes resources, especially packaging plastics and domestic plastics, which account for a large proportion of waste plastics. Plastic waste recycling is an important way to turn waste into treasure and solve ecological environmental pollution. [0003] At present, waste plastics will be compressed and stored after being recycled to the waste plastics treatment site, and then melted in a reactor and then granula...
