Recycling Plastic Cleaning Equipment: An In – Depth Exploration

In the context of increasing environmental awareness and the growing demand for sustainable development, recycling plastic cleaning equipment has become an essential part of the plastic recycling industry. These devices play a crucial role in removing contaminants from waste plastics, making them suitable for further recycling and reuse. This article will comprehensively introduce recycling plastic cleaning equipment, including its working principles, types, applications, advantages, and price ranges.

Working Principles of Recycling Plastic Cleaning Equipment

Pre – treatment

Before the main cleaning process, the waste plastics usually undergo a pre – treatment step. This step is mainly to remove large – sized contaminants, such as stones, metals, and large pieces of paper. The pre – treatment can be carried out by methods such as screening, magnetic separation, and air separation. For example, a vibrating screen can be used to separate large – sized waste plastics from small – sized contaminants, and a magnetic separator can be used to remove ferrous metals from the waste plastics.

Main Cleaning

The main cleaning process is the key step in removing dirt, oil, and other contaminants from the waste plastics. It usually involves the use of cleaning agents and mechanical agitation. The waste plastics are placed in a cleaning tank filled with a cleaning solution. The cleaning solution can be a mixture of water and a suitable cleaning agent, such as a detergent or a degreaser. The tank is equipped with agitators or paddles that stir the waste plastics and the cleaning solution, ensuring that the contaminants are effectively removed. The temperature and time of the cleaning process can be adjusted according to the type and degree of contamination of the waste plastics.

Rinsing

After the main cleaning, the waste plastics need to be rinsed to remove the cleaning agent and any remaining contaminants. Rinsing is usually carried out in a separate rinsing tank filled with clean water. The waste plastics are repeatedly washed with water until the water is clear. This step is important to ensure that the final recycled plastics are clean and free of any residues.

Drying

The final step in the cleaning process is drying. The rinsed waste plastics contain a certain amount of moisture, which needs to be removed before further processing. Drying can be achieved by methods such as air drying, hot – air drying, or centrifugal drying. For example, a centrifugal dryer can be used to spin the waste plastics at high speed, removing the moisture through centrifugal force. After drying, the waste plastics are ready for the next processing steps, such as melting and pelletizing.

Types of Recycling Plastic Cleaning Equipment

Batch – type Cleaning Equipment

Batch – type cleaning equipment is suitable for small – scale recycling operations. It processes the waste plastics in batches, which means that a certain amount of waste plastics is loaded into the cleaning tank at a time, and the cleaning process is completed before the next batch is loaded. This type of equipment is relatively simple in structure and easy to operate, but it has a low production capacity.

Continuous – type Cleaning Equipment

Continuous – type cleaning equipment is designed for large – scale recycling operations. It can continuously feed the waste plastics into the cleaning tank and carry out the cleaning process without interruption. This type of equipment has a high production capacity and can ensure a continuous supply of clean waste plastics for the subsequent processing steps. However, it is more complex in structure and requires more advanced control systems.

Ultrasonic Cleaning Equipment

Ultrasonic cleaning equipment uses ultrasonic waves to generate high – frequency vibrations in the cleaning solution. These vibrations create microscopic bubbles that implode on the surface of the waste plastics, removing the contaminants through a process called cavitation. Ultrasonic cleaning is a very effective method for removing stubborn contaminants, such as oil and grease, from the waste plastics. However, it is relatively expensive and may not be suitable for all types of waste plastics.

Friction Cleaning Equipment

Friction cleaning equipment uses mechanical friction to remove the contaminants from the waste plastics. The waste plastics are rubbed against each other or against a rough surface, such as a wire brush or a sandpaper – lined drum. This type of equipment is simple in structure and low in cost, but it may cause some damage to the waste plastics and may not be able to remove all types of contaminants.

Applications of Recycling Plastic Cleaning Equipment

Plastic Recycling Plants

Recycling plastic cleaning equipment is widely used in plastic recycling plants. It can clean waste plastics from various sources, such as household waste, industrial waste, and post – consumer waste. The cleaned waste plastics can then be further processed into recycled plastic products, such as plastic granules, which can be used as raw materials for the production of new plastic products.

Manufacturing Industries

Some manufacturing industries also use recycling plastic cleaning equipment to clean the plastic waste generated during their production processes. By recycling and reusing the cleaned plastic waste, these industries can reduce their production costs and improve their environmental performance. For example, a plastic injection – molding factory can use the cleaning equipment to clean the plastic waste generated during the injection – molding process, and then reuse the cleaned plastic waste in the production of new plastic parts.

Environmental Protection Organizations

Environmental protection organizations may use recycling plastic cleaning equipment to clean the plastic waste collected from the environment, such as beaches, rivers, and oceans. This helps to reduce the environmental impact of plastic pollution and promotes the sustainable use of plastic resources.

Advantages of Recycling Plastic Cleaning Equipment
