Abstract

The invention relates to the technical field of PET cruse flake recovery and granulation, in particular to a continuous vacuum drying reaction device and system. The continuous vacuum drying reactiondevice and system are mainly used for performing drying treatment on recovered PET cruse flakes and peculiar smell removal on particles after being granulated, and comprise a negative pressure hopper,a PET cruse flake preheating device, a vacuum reactor, a buffer bin and a vacuum pump assembly, wherein the PET cruse flake preheating device comprises a blower, a heater, a bag-shaped filter, a dryer A and a dryer B. The continuous vacuum drying reaction device and system can enable the recovered PET cruse flakes to form a stable piston flow in a vacuum reactor, and the energy consumption low treatment effect is good.

Description

technical field [0001] The invention relates to the technical field of recycling and granulation of bottle flakes, in particular to a continuous vacuum drying reaction device and system, which mainly performs drying treatment on recycled bottle flakes and removes peculiar smell from granulated particles. Background technique [0002] The existing equipment is drum drying equipment or other drying equipment, artificial and intermittent operation, can only be used for laboratory or small-scale batch production, and cannot realize automatic control; the products produced by the existing equipment are per drum and each batch The performance cannot be exactly the same; the existing equipment has poor drying effect when drying PET recycled bottle flakes, high energy consumption, it is difficult to handle the water content of the material below 50ppm, and the equipment is not easy to maintain. Contents of the invention [0003] In view of this, the present invention proposes a co...
