A plastic pellet recycling system

Abstract

The invention discloses a plastic granule recycling system, which belongs to the field of plastic recycling. The plastic granule recycling system firstly crushes waste plastics and then cleans them, and puts the cleaned plastic granules with water into an internal drying system. On the one hand, when the inner drying cylinder is rotating, under the action of centrifugal force, the water adhering to it will be thrown into the outer shell to contact with the overflow gas packing, so that the overflow gas packing will generate gas and Reverse osmosis into the inner drying cylinder, so as to loosen the plastic particles to a certain extent, and accelerate the overflow of hot and humid air inside it due to heating. On the other hand, when the inner drying cylinder rotates, the water capsules collide with each other and cause rupture. The internal water overflows and spreads with the rotation, which significantly increases the gas production speed and gas production volume in the outer cladding, accelerates drying, and greatly improves the recovery efficiency compared with the existing technology.

Description

technical field [0001] The invention relates to the field of plastic recycling, and more specifically, relates to a plastic particle recycling system. Background technique [0002] Plastic is a high molecular compound polymerized by addition polymerization or polycondensation reaction with monomer as raw material. It is commonly known as plastic or resin. It can freely change its composition and shape. , Colorants and other additives. In the plastic recycling process, the cleaning and sorting of waste plastics is very important. [0003] In the prior art, the waste gas plastics are first crushed, then the plastics are cleaned, and then dried to complete recycling. However, during the drying process, due to the small particles, there is a large amount of adhered water in them, resulting in a large amount of heat and humidity during drying. Air, but the water vapor inside the particles is discharged slowly, and it is prone to temperature with poor drying uniformity, which af...

Problems solved by technology

[0003] In the prior art, the waste gas plastics are crushed first, then the plastics are cleaned, and then dried to complete the recovery. However, during the drying process, due to the small particles, there is a lot of adhered water in them, resulting in a large amount of heat and humidity during drying. Air, but the water vapor located inside the particles is discharged slowly, and it is prone to temperature with poor drying uniformity, which affects the drying speed and leads to low overall recovery efficiency
