Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of plastic recycling, and specifically relates to a heating device for plastic recycling. BACKGROUND
[0002] Plastic recycling refers to the process of collecting, classifying, cleaning, melting and remanufacturing waste plastic products to convert them into raw materials or products that can be reused, thereby achieving the purpose of saving resources, reducing environmental pollution and reducing energy consumption.
[0003] The overall structure of the existing plastic recycling heating device is relatively simple, and this simple structure directly leads to the limitation of the stirring function. In actual operation, the stirring rod is difficult to fully mix the plastic uniformly when stirring the plastic material. Due to the insufficient stirring, a large amount of plastic will gradually deposit at the bottom of the heating tank, forming a thick accumulation layer. This phenomenon will cause a series of adverse consequences, for example, the plastic accumulation layer will hinder the uniform transfer of heat in the heating tank, causing uneven heating of the plastic in different areas of the tank, thereby seriously affecting the overall heating effect of the plastic recycling device, prolonging the heating time, increasing energy consumption, and reducing the recycling efficiency. In addition, the existing plastic recycling heating device also has obvious deficiencies in later maintenance and cleaning. The cleaning tool cannot reach the corners of the device, and cannot completely remove the residual plastic impurities, dirt and possible chemical deposits. Over time, these residual substances not only affect the heating performance of the device, but also breed bacteria and corrode equipment components, further reducing the service life and recycling quality of the device, increasing equipment maintenance and replacement costs, and bringing many inconveniences and economic burdens to plastic recycling enterprises.
