Abstract:
A waste foamed polystyrene material reclaiming system comprising:a crusher adapted to crush washed foamed polystyrene material crushed waste foamed polystyrene material;a solvent storage tank holding a solvent;a first mixer adapted to mix the solvent from said solvent storage tank with the crushed waste foamed polystyrene material from said crusher into a paste-like material;a dissolving material storage tank connected to said first mixer and adapted to store the paste-like material obtained from said first mixer;a filter connected to said dissolving material storage tank and adapted to filter the paste-like material;a second mixer connected to said filter and adapted to mix the filtrate obtained through said filter;a filtrate storage tank adapted to store the well-mixed filtrate obtained from said second mixer;a distiller connected to said filtrate storage tank and adapted to distill said well-mixed filtrate into evaporated solvent and reclaimed polystyrene material;an overflow valve connected between said distiller and said filtrate storage tank for enabling overflow of well mixed filtrate to be returned to said filtrate storage tank;a condenser connected to said overflow valve and adapted to condense said evaporated solvent into a liquid state solvent;a solvent recycling tower connected between said condenser and said solvent storage tank;an induced-draft fan adapted to draw waste gas from said distiller into the atmosphere;an extruder connected to said distiller and adapted to extrude said reclaimed polystyrene material into a mass of soft polystyrene material;a water tank connected to said extruder and adapted to cool down said mass of soft polystyrene material with water; anda cutting machine adapted to cut hardened mass of soft polystyrene material obtained from said water tank into grained-like reclaimed polystyrene material.
