Plastic sorting equipment is designed specifically for the high-quality recycling of waste plastics. It can purify and remove impurities from crushed mixed aggregates, and achieve large-scale, automated, and high-purity recycling of various recyclables such as PET and PP. The intelligent optical sorting machine relies on the speed of the belt conveyor and recognition algorithms for sorting, while the picking robot can select items based on interchangeable end effectors, ensuring high sorting accuracy and meeting diverse recycling needs.
I. Intelligent Optical Sorting Machine
The intelligent optical sorting machine is one of the commonly used plastic sorting devices. Its structure includes a high-speed belt conveyor, an intelligent recognition algorithm, and a dense array of directional airflow at the rear end. During operation, the belt conveyor runs at a speed of up to 3m/s, capable of processing a row of materials at a time. By leveraging this high-speed operation and intelligent recognition, the machine can identify plastics in mixed aggregates and then precisely sort them using the airflow at the rear end. It is particularly suitable for processing large quantities of items, such as purifying and removing impurities from plastics in mixed aggregates of less than 20mm in size generated from crushed construction and demolition waste, achieving large-scale, automated, and high-purity recycling of waste plastics.
II. Intelligent Picking Robot
The intelligent picking robot is also a commonly used plastic sorting device. It is equipped with three types of interchangeable end effectors: soft grippers, suction cups, and alloy grippers. This robot can intelligently pick up recyclables such as plastic bottles, Tetra Pak containers, and cardboard. It is mainly used for impurity removal and can select the appropriate end effector based on different needs. For example, when dealing with impurities of different shapes or material characteristics, it can choose soft grippers for relatively soft impurities, suction cups for easily adsorbed impurities, and alloy grippers for harder impurities, and perform sorting operations on various items.
III. Electrostatic Separator for Mixed Plastics
The electrostatic separator for mixed plastics is a device specifically designed for sorting mixed plastic materials. It operates using dry physical electrostatic separation technology. By placing crushed plastics into the machine, it can sort 2 - 3 types of mixed plastics based on their different electrical charge characteristics, achieving a very high separation purity of over 99%. Additionally, this equipment is equipped with a pulse dust removal environmental protection device, which can collect all the dust generated during operation, thus realizing a pollution-free production mode. It has the advantages of environmentally friendly processes and simple operation, making it suitable for sorting mixed plastics such as PET, PVC, and PC.
IV. Plastic Color Sorting Machine
The plastic color sorting machine mainly identifies and sorts mixed plastics based on their colors. When plastic materials pass through the color sorting machine, it quickly detects the colors of the plastics and sorts them according to the settings. This type of equipment has a relatively fast sorting speed, but its disadvantage is that it is easily affected by lighting conditions. If the lighting is poor, it may result in incomplete sorting. However, it can still perform well in sorting relatively large-sized plastics with obvious color differences, where the sorting purity requirement is not extremely high and the working environment has stable lighting conditions.
V. Sorting Equipment with Machine Vision Technology
This type of equipment can detect characteristics such as the color, shape, and size of plastic waste. For example, it is used to process plastics such as polyethylene, polypropylene, polystyrene, polyvinyl chloride, and polyurethane. Machine vision technology is equivalent to giving the equipment "eyes," allowing it to accurately classify and clean plastics based on the detected characteristics. This type of equipment also features energy saving and low energy consumption, effectively saving energy and reducing environmental pollution. It performs well in improving work efficiency and saving labor, while also enhancing the accuracy and quality of sorting. This equipment helps reduce environmental pollution, protect soil and water sources, and achieve sustainable resource utilization. It has positive significance in solving waste sorting problems and is suitable for sorting mixed plastic waste.
