Abstract

The invention discloses a PET (polyethylene terephthalate) air flotation separation device which is characterized by comprising main equipment such as a pressure pump, a dissolved air tank, an air compressor and an air flotation cleaning tank. Air in the dissolved air tank is pressurized and dissolved into water to reach a saturation state so as to form dissolved air water; after the air flotation cleaning tank is filled with the dissolved air water, microbubbles released from the dissolved air water can be attached to the surface of a separation material to change the buoyancy force of the separation material so as to achieve the purpose of separation. Impurities with different specific gravities in PET raw materials can be effectively separated by adjusting the proportion of the dissolved air water in filled cleaning water. The PET air flotation separation device is of a cleaning tank structure, can be conveniently embedded into a PET recovery production line, and is capable of automatically separating out the impurities from the PET raw materials to achieve the purpose of quality control and effectively improve the market competition advantage of enterprises.

Description

technical field [0001] The invention relates to a sorting device, in particular to sorting trademark paper from PET raw materials. Background technique [0002] Polyethylene terephthalate (PET) is a synthetic material that has been widely developed since the second half of the 1960s. The product variety of PET has expanded from the initial polyester staple fiber to polyester staple fiber, polyester filament, polyester Ester bottles, polyester films, non-woven fabrics, engineering plastics and composite multi-functional products, etc., have hundreds of products and thousands of specifications. Due to the continuous increase of social demand, the production of PET polyester has grown rapidly. my country's PET production capacity has exceeded 20 million tons in 2008, becoming the world's largest producer and consumer of PET. [0003] PET products are mostly disposable consumer goods, followed by a large amount of waste PET materials. Waste PET materials are chemically inert ...
