Description

Technical Field

[0001] This utility model relates to the field of plastic material pretreatment technology, specifically a plastic material pretreatment device. Background Technology

[0002] Pretreatment of plastic materials is a key step in the plastic processing process. Its purpose is to remove impurities from the material, regulate humidity, improve processing performance, and ensure the smooth progress of subsequent molding processes and the stability of product quality.

[0003] Chinese patent discloses a plastic material pretreatment device (authorization announcement number CN117124500B). This patented technology quickly removes impurities and oil stains from the surface of plastic granules, saving washing water. Secondly, after washing, the water inlet is closed, and only compressed air is used to agitate the plastic granules. The high-speed airflow quickly removes water stains from the surface of the plastic granules and carries away the generated particle debris, thus performing a pretreatment to remove impurities from the plastic granules. Compared to vigorous mechanical agitation, this reduces the generation of debris. However, the aforementioned plastic material pretreatment device relies entirely on rinsing and stirring to clean the plastic material, resulting in a low level of cleanliness, which is detrimental to the processing efficiency of the plastic material. Furthermore, the removal of lightweight contaminants is inconvenient, affecting the cleaning effect of the aqueous solution.
