At a time when the global environmental situation is becoming increasingly severe, the problem of plastic pollution has become a key issue that needs to be solved urgently. Retech's HDPE PP bottle washing and recycling production line came into being. It focuses on processing various types of waste plastic materials. Whether it is common PP, PE, LDPE, LLDPE films, or HDPE PP bottles, etc., they can all be transformed in its efficient process. From waste oil drums, HDPE milk bottles, beer barrels, oil tanks, shampoo bottles, to hard plastic materials in electronic waste, waste pipes and injection molding waste, all are within the scope of its powerful processing capabilities, providing strong technical support for solving the problem of plastic waste.
(1)Crushing pretreatment - reshaping the plastic form
The processing flow of the "RT" series HDPE PP bottle washing and recycling production line starts with the crushing link. The double-axis shredder and crusher work together, like a brave pioneer, challenging rigid plastics of various shapes and thicknesses. Whether it is waste HDPE bottles of various shapes, tough PP tubes, stubborn lumps, or complex injection molds, they are all crushed into pieces of appropriate size under their strong force. This process lays a solid foundation for subsequent cleaning and processing, ensuring that the plastic raw materials can fully contact with the cleaning reagents and equipment, and improving processing efficiency.
(2)Deep cleaning - cleansing plastic pollution
Entering the cleaning stage, the production line shows a rich variety of cleaning methods. The hot washing function is particularly eye-catching. When facing plastics that are severely contaminated by chemicals or oil, the hot washing process is very effective. In a specific temperature and chemical reagent environment, the adhesion between the pollutant molecules and the plastic surface is effectively weakened, thereby achieving deep cleaning. At the same time, the label adsorption system cleverly uses the principle of gravity, like a precise sorting master, to accurately separate lightweight labels from plastic sheets. This not only ensures the purity of the recycled plastic, but also avoids the interference of label impurities in subsequent processing links, ensuring that each piece of plastic can meet higher quality standards.
(3)Precision drying - locking in ideal humidity
The drying link is one of the key control points of the production line. The high-speed rotary centrifugal dryer shoulders the heavy responsibility. With its advanced technology and powerful centrifugal force, it can accurately control the humidity of plastics within 1%. During the high-speed rotation process, the moisture is quickly thrown off the surface of the plastic, so that the plastic reaches a nearly ideal dry state. This precise humidity control provides stable and reliable raw material conditions for subsequent granulation or other processing procedures, ensuring the continuity and stability of the entire production process and reducing product quality problems that may be caused by excessive moisture.
In terms of technical parameters, different models of HDPE PP bottle washing and recycling production lines provide diversified choices for various companies. Taking RM-1000, RM-2000, and RM-3000 as examples, the RM-1000 model has a power of 160kw/h, a water consumption of 3-4 t per hour, and a production capacity of up to 1000kg/h, which is suitable for small and medium-sized enterprises or production scenarios with strict control of energy consumption. The power of RM-2000 is increased to 280kw/h, the water consumption is 4-5 t/h, and the production capacity is 2000kg/h, which can meet the production needs of medium-sized enterprises and achieve a good balance between production capacity and energy consumption. The power of RM-3000 is 360kw/h, the water consumption is 5-6 t/h, and the production capacity is up to 3000kg/h, which provides efficient production solutions for large-scale plastic recycling and processing enterprises, helping enterprises to achieve large-scale and efficient plastic recycling.
Quality assurance is the core competitiveness of the HDPE PP bottle washing and recycling production line. After careful treatment by its efficient film washing unit, the final plastic material has reached a remarkably high standard in cleanliness and dryness, and the moisture content is strictly controlled below 1%. This outstanding achievement is due to its selection of high-quality components. As the power core, Siemens motors ensure the continuous and stable operation of the equipment with stable and reliable performance, providing a steady stream of power support for the entire production process. NSK bearings play a key role in various mechanical operation parts. With their high precision and high durability, they effectively reduce friction loss during equipment operation and ensure the smooth operation of mechanical parts. SKD-11 cutters perform well in the crushing process. With their hard material and sharp edges, they can easily cope with the crushing tasks of various types of plastics. They also have excellent wear resistance, which prolongs the service life of the cutters and reduces equipment maintenance costs and downtime.
The HDPE PP bottle washing and recycling production line occupies an important position in the plastic recycling industry with its advanced technology, fine process, multiple parameter adaptation and reliable quality assurance. It not only strongly promotes the reduction and resource utilization of plastic waste, reduces the harm of plastic waste to the environment, but also provides enterprises with efficient recycling and processing solutions, reduces production costs, and improves economic benefits. It has become a key driving force for the sustainable development of the modern environmental protection industry and the plastic processing industry, leading the plastic recycling industry to a better future.
