Description

Line for the processing of used polyethylene terephthalate products.

The utility model relates to means for processing products from polyethylene terephthalate (PET) for reuse in the manufacture of various products.

Currently, a fairly large number of plants are known for processing various products from plastic materials, for example, Japanese Patent No. 2002-254430 dated November 9, 2002; US patent No. 6460788 from 08/10/2002; RF patent No. 2200659 dated March 20, 2003; Spanish patent No. 544548/5 of 01.25.1985.

A disadvantage of the known technological processes is their low efficiency in the processing of PET products, in particular PET bottles, the use of which has now increased significantly.

The technical result to which the invention is directed is to create a technology for the processing of used PET products for their subsequent use.

The specified result is achieved by the fact that the processing line of used products from polyethylene terephthalate (PET) contains a conveyor associated with the grinder, with the first

  o- -, IL ..,.

a storage hopper, the input of which is connected to a soaking bath, designed to separate the flexes from the light fractions, equipped with a bottom screw, consisting of two parts of the right and left windings, and connected with a discharge screw for transferring partially cleaned flexes to the first centrifuge, designed to separate the latter from water and dirt and a bath-related hot wash associated with a rinse bath designed to clean the fleks from detergents and connected to a third unloaded auger for conveying the cleaned flexo a third centrifuge, connected with the drying cyclone associated with the dispenser intended for dispensing portions of product into a hot air stream into the conduit provided with a fan and a heater and associated with the second storage hopper connected to the means flake packing.

The utility model is illustrated in the drawing, which shows a General view of the processing line of PET products.

The processing line for used PET products consists of a control panel 1, chopper 2, fan 3, storage bins 4 and 5, soaking bath 6, dynamic centrifuges 7, 8 and 9, hot washing bath 10, rinsing bath 11, sedimentary bath 12, drying systems 13.

the line for non-processing of PET products operates as follows.

The initial product for non-processing are used products made of nolyethylene terephthalate.

The product enters the chopper 2 (crusher) using a conveyor. From the grinder through pneumatic transport, the product enters the storage cyclone 4 (storage hopper). The crushed product is poured into a soaking bath 6, where the product is moistened and mixed using a barbator. The product sinks, floating particles are removed from the surface of the bath with a spinner. With the help of a bottom and discharge screw, the product enters the centrifuge 7.

In a centrifuge 7, the product is separated from water and “dirt.” Using the centrifugal forces of the centrifuge fans (located in the upper part of the centrifuge), it directs the product through pneumatic conveying into the cyclone 14 and enters the hot washing bath 10.

In the hot washing bath 10, the product is washed in a solution of detergents, then with the help of an unloading screw it enters the centrifuge 8.

In a centrifuge 8, the product is separated from water and impurities and through pneumatic transport enters the rinse bath 11.

in the bath And rinsing, the product is washed from detergents and with the help of the unloading screw it enters the sedimentary bath 12.

In sedimentary bath 12, the product is deposited on the bottom of the bath, and floating particles are removed using a spinner. From the bottom of the bath, the product is discharged by a discharge screw to a centrifuge 9.

In a centrifuge 9, the product is separated from the water and fed via pneumatic conveying to the cyclone 15 of system 13. From the cyclone 15 to the dispenser, which evenly feeds the product into the stream of hot air.

The air is sucked in by the fan through the air heater, where the air is heated to a certain temperature and fed via pneumatic transport to the storage hopper 5. The product is heated in a stream of hot air moving into the storage hopper and dries. Here the flakes are completely dehydrated, dried and accumulated in the hopper for future use.
