Abstract
A waste foamed polystyrene material reclaiming method includes the steps of waste material crushing, solvent mixing, filtering, secondary mixing, distilling, evaporated solvent condensing and recycling, reclaimed polystyrene material heating, reclaimed polystyrene material extruding, extruded mass of reclaimed polystyrene material cooling, and grain-cutting.
Claims1
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;
- and
- a cutting machine adapted to cut hardened mass of soft polystyrene material obtained from said water tank into grained-like reclaimed polystyrene material.
