Plastic particle winnowing and classifying device based on variable-frequency speed-regulating fan

Abstract

The invention relates to a plastic particle winnowing and classifying device based on a variable-frequency speed-regulating fan and belongs to the field of environmental protection. The plastic particle winnowing and classifying device comprises a particle feeding opening, a fan device and other components. The particle feeding opening is connected with a density winnowing and classifying device, the density winnowing and classifying device is connected with a soot cleaning water curtain and a conveyor belt of matters of various densities correspondingly, the conveyor belt of the various matters is connected with a single-matter collection slot, the soot cleaning water curtain is connected with a wet wind drying device, the wet wind drying device is connected with a wind circulation system, the wind circulation system is connected with the fan device, the fan device is connected with the density winnowing and classifying device, and a power source is connected with the fan device, the particle feeding opening and the conveyor belts of the matters of various densities correspondingly. By means of the plastic particle winnowing and classifying device, the mixed matters can be effectively classified, winnowing and classifying are performed based on difference in the particle densities, design is simple, environmentally friendly and efficient, a great role is played on classification of the plastic particles, and certain contribution can be made to environmental protection.

Description

technical field [0001] The invention relates to a plastic granule winnowing and classifying device based on a variable-frequency speed-regulating fan, which belongs to the field of environmental protection. Background technique [0002] Since the invention of plastics, people have enjoyed the convenience brought by plastics. Plastics have been favored by people all over the world for their simplicity and ease of production. At the same time, people are enjoying the convenience brought by plastic products to the whole society. The whole planet has brought a big problem, plastic waste. Plastic waste means that after plastic products are used, they are not effectively disposed of. Plastic is composed of polymer substances, so conventional methods cannot degrade quickly. The common way to deal with it is to stack it in the open air, which pollutes the environment and wastes land. Although centralized incineration can use its calorific value to generate electricity, the emission...

Plastic is composed of polymer substances, so conventional methods cannot degrade quickly. The common way to deal with it is to stack it in the open air, which pollutes the environment and wastes land. Although centralized incineration can use its calorific value to generate electricity, the emissions will cause air pollution. , and the use of chemical methods is not only costly, but also causes secondary pollution
