Abstract

This invention relates to the field of plastic pellet manufacturing technology and discloses a recycled plastic compounding and granulation machine with multi-stage filtration and impurity removal function. It includes a mixing and melting device, a feeding device located at the top of the mixing and melting device, an end-filter device located on the side of the mixing and melting device, and an outlet head located on the side of the end-filter device away from the mixing and melting device. The end-filter device includes a filter connector located at the output end of the mixing and melting device. This recycled plastic compounding and granulation machine with multi-stage filtration and impurity removal function, by incorporating the end-filter device, allows molten raw materials to enter a connecting tank during operation, then pass through the filter assembly and support frame. Impurities in the raw materials are intercepted by the filter assembly, thus ensuring the purity of the outflowing raw materials. Simultaneously, the cylindrical shape of the support frame and fine filter increases the flow area of ​​the raw materials, effectively improving equipment production efficiency while also making the equipment less prone to clogging.
