Description
Technical Field
[0001] The utility model relates to the technical field of polystyrene rotary sieving machines, in particular to a rotary sieving machine for polystyrene. Background Art
[0002] Polystyrene is a common plastic material with a wide range of uses and applications. It usually exists in two forms: one is a colorless and transparent solid, and the other is a foamed form, namely expanded polystyrene. Polystyrene has good mechanical properties, chemical corrosion resistance and excellent electrical insulation properties. It is a colorless, transparent and hard plastic, which is easy to be processed into various shapes and has good surface finish. Polystyrene is widely used in various fields, such as making thermal insulation and sound insulation materials, insulation boards, decorative materials, electrical appliance shells, insulating materials, electronic components, medical equipment accessories and test tubes, etc. Therefore, polystyrene needs to be filtered, screened and used according to different requirements. At present, most of the rotary sieving machines in the prior art are flat, resulting in poor screening effect on polystyrene, unable to provide a larger screening surface, unable to effectively screen polystyrene with different particle sizes at the same time and uniformly collect polystyrene with different particle sizes, thus reducing the screening efficiency of polystyrene. Moreover, when feeding materials into the rotary sieving machine, the materials cannot be effectively stirred, which may cause material blockage in the feed hopper and the screening cylinder. Therefore, we propose a rotary sieving machine for polystyrene to solve this problem. Summary of the Utility Model
