Convective dryer for biodegradable plastic granules

Abstract

The invention discloses a convective dryer for biodegradable plastic particles, which belongs to the field of drying biodegradable plastics. A convective dryer for biodegradable plastic particles includes a convective dryer body, and a suction device is fixedly installed inside the convective dryer body. Dust diffusion drying bag, the upper and lower inner walls of the dust absorption diffusion drying bag are rotated and connected with a diffusion convection air cover, which can make biodegradable plastic particles in the dust absorption diffusion drying bag through the cooperation of the diffusion convection air cover and the convection isolation drying system. Suspension separation state, and then effectively realize the convective suspension isolation and drying of biodegradable plastic particles, thereby reducing the contact between biodegradable plastic particles and their contact with the dust-absorbing diffusion drying bag, and reducing the adhesion of dust and dust on the wall of biodegradable plastic particles during drying. Reduce the probability of impurities, effectively avoid the contamination of biodegradable plastic particles, and improve the drying quality of the convection dryer body.

Description

technical field [0001] The invention relates to the field of drying biodegradable plastics, in particular to a convective dryer for biodegradable plastic particles. Background technique [0002] Biodegradable plastics refer to a class of plastics that are degraded by the action of naturally occurring microorganisms such as bacteria, molds (fungi) and algae. The ideal biodegradable plastic is a polymer material that has excellent performance, can be completely decomposed by environmental microorganisms after being discarded, and is finally inorganicized to become an integral part of the carbon cycle in nature. "Paper" is a typical biodegradable material, while "synthetic plastic" is a typical polymer material. Therefore, biodegradable plastics are polymer materials that have the properties of both "paper" and "synthetic plastics". [0003] Biodegradable plastics are made by compounding various materials, and are mainly processed through the steps of melting and mixing by me...

Problems solved by technology

[0004] At present, hot air dryers are mostly used to dry biodegradable plastic particles, and the hot air takes away the moisture on the surface of biodegradable plastic particles to achieve the drying effect. If the temperature is too high, the surface of the biodegradable plastic particles will be softened, and the residual impurities or dust in the dryer will easily adhere to the surface of the biodegradable plastic particles, causing pollution to the biodegradable plastic particles, thereby reducing the purity of the biodegradable plastic particles and reducing the drying efficiency.
