Abstract
The invention discloses a closed type multi-stage waste polypropylene cleaning and refining system which consists of a conveyer belt, a crushing machine, a low-speed friction cleaning machine A, a material loading machine A, a precipitation cleaning basin A, a material loading machine B, a high-speed friction cleaning machine, a low-speed friction cleaning machine B, a material loading machine C, a precipitation cleaning basin B, a material loading machine D, a plasticizing device, a drying device and a material storehouse which are connected with one another in sequence. The closed type multi-stage waste polypropylene cleaning and refining system crushes waste polypropylene through the crushing machine; then the waste polypropylene is subjected to low-speed friction cleaning, high-speed friction cleaning and secondary low-speed friction cleaning in sequence and is plasticized and dried, so that the waste polypropylene can be effectively separated and is cleaned and processed into a preliminary polypropylene master batch; therefore, the quality of a subsequent product is improved.
Description
Technical field:
The invention belongs to a kind of cleaning equipment, particularly a kind of cleaning of closed multistage waste and old polypropylene, refining system.
Background technology:
In plastics in various waste products, not only contain the additive of many types, and normal and other plastic materials combine, so are very stubborn problems to their recovery and reuse, as first must differentiated, classification, Isolation and screening, then use suitable PROCESS FOR TREATMENT.Polypropylene, it can be divided into three kinds of HOPP (PP-H), block copolymerization polypropylene (PP-B) and atactic copolymerized polypropenes (PP-R) according to the difference of molecular morphosis.The difference of these three kinds of material structures makes them have different application characteristics, therefore also has different purposes.Meanwhile, waste and old polypropylene inside also may mix a small amount of polyethylene (PE), polystyrene (PS), polymethyl methacrylate (other plastic products such as PMMA, terylene (PET) and nylon 66.Therefore, before its cycling and reutilization, in addition effectively separatedly for follow-up product quality, there is material impact.
Summary of the invention:
Object of the present invention is just to provide a kind of cleaning, refining system of closed multistage waste and old polypropylene, and this system can realize the quick separation of waste and old polypropylene, and waste and old polypropylene surface cleaning is become to elementary polypropylene masterbatch.
As above design, technical scheme of the present invention is: a kind of cleaning of closed multistage waste and old polypropylene, refining system, is characterized in that: by conveyer belt, disintegrating machine, low speed friction cleaning machine A, feeder A, precipitation service sink A, feeder B, high-speed friction cleaning machine, low speed friction cleaning machine B, feeder C, precipitation service sink B, feeder D, plasticizing apparatus, drying device and storage bin, connected to form successively.
Above-mentioned drying device adopts centrifugal drier or duct-type drier.
The present invention by waste and old polypropylene after crusher in crushing, successively through low speed friction clean, after high-speed friction is cleaned, low speed friction cleans, plastify again, be dried, can be effectively that waste and old polypropylene is separated, its surface cleaning is become to elementary polypropylene masterbatch, thereby improve the quality of subsequent product.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
In figure: 1. conveyer belt, 2. disintegrating machine, 3. low speed friction cleaning machine A, 4. feeder A, 5. precipitation service sink A, 6. feeder B, 7. high-speed friction cleaning machine, 8. low speed friction cleaning machine B, 9. feeder C, 10. precipitation service sink B, 11. feeder D, 12. plasticizing apparatus, 13. wind send device, 14. pipe driers, 15. storage bins.
The specific embodiment:
As shown in the figure: a kind of cleaning of closed multistage waste and old polypropylene, refining system, send device, pipe drier and storage bin to connect to form successively by conveyer belt, disintegrating machine, low speed friction cleaning machine A, feeder A, precipitation service sink A, feeder B, high-speed friction cleaning machine, low speed friction cleaning machine B, feeder C, precipitation service sink B, feeder D, plasticizing apparatus, wind.Above-mentioned high-speed friction cleaning machine adopts our company's patent high-speed friction cleaning equipment (CN201220646077.2).Utilize this device waste and old polypropylene surface cleaning can be become to elementary polypropylene masterbatch.Both can be used for producing the low grade products such as woven bag, also can externally sell.
