Plastic particle recycling system

Abstract

The invention discloses a plastic particle recycling system, and belongs to the field of plastic recycling. According to the plastic particle recycling system, during recycling, waste plastic is crushed and then cleaned, cleaned plastic particles with water are put into an inner drying cylinder, the inner drying cylinder rotates, on one hand, when the inner drying cylinder rotates, under the action of centrifugal force, water adhered to the plastic particles is thrown into an outer adhering wrapping shell to be in contact with air overflowing filler, and the air overflowing filler generates air and reversely permeates into the inner drying cylinder, so that the plastic particles are loosened to a certain extent, and the overflow of damp and hot air generated by heating inside the plastic particles is accelerated; and on the other hand, when the inner drying cylinder rotates, water capsules mutually collide with each other and are broken, internal water overflows and diffuses along with rotation, so that the air production speed and the air production rate in the outer adhering wrapping shell are remarkably increased, drying is accelerated, and compared with the prior art, the system has the advantage that recovery efficiency is greatly improved.

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
