Multistage dispensing equipment applied to production of regenerative polypropylene

Abstract

The invention discloses multistage dispensing equipment applied to production of regenerative polypropylene. The multistage dispensing equipment comprises a first-stage dispensing device, a second-stage dispensing device and a third-stage dispensing device, wherein the first-stage dispensing device comprises a plurality of first dispensing lines for mixing first-stage materials into second-stage materials, the second-stage dispensing device comprises a plurality of second dispensing lines for mixing second-stage materials into third-stage materials, the third-stage dispensing device comprises a plurality of third dispensing lines for mixing third-stage materials into fourth-stage materials by adding an additive; and each first dispensing line is used for sending the first-stage materials to the first dispensing line through a first feeding mechanism for mixing and dispensing the materials, each first dispensing line is used for feeding the second-stage materials to the plurality of dispensing lines through a second feeding mechanism for mixing and dispensing the materials; and each second dispensing line is used for feeding the third-stage materials to each corresponding third dispensing line through a third feeding mechanism for mixing and dispensing the materials. By adopting the multistage dispensing equipment, when dispensing is performed, the automatic dispensing is realized, and the dispensing efficiency is increased; and the materials are more uniformly dispensed through three stages of mixing, and thus the quality of the polypropylene fibers is improved.

Description

technical field [0001] The invention relates to the field of recycled polypropylene production equipment, in particular to multi-stage batching equipment applied to the production of recycled polypropylene. Background technique [0002] With the development of recycling technology, many waste plastics can be reused in the production of polypropylene, which not only reduces the production cost of enterprises, but also greatly reduces environmental pollution. When using waste plastics for the production of recycled polypropylene, the waste plastics need to be cut, cleaned, dehydrated and dried, batched, melted and other processes, and finally drawn to form products. [0003] In the batching process of recycled polypropylene production, it is necessary to uniformly mix and batch a variety of waste plastics, and then add additives and melt them. The existing batching process for the production of recycled polypropylene uses manual batching to mix a variety of waste plastics and...
