Abstract: PURPOSE: A processing unit of reducing the bulk of a waste Styrofoam is provided to gain extrusion product which is ingoted into an extrusion dice and to cut the ingoted extrusion dice into constant length, thereby an ingoted processed product can be packed or stored or moved so that it can be produces into a small bulk. CONSTITUTION: A processing unit of reducing the bulk of a waste Styrofoam includes a grinding uni(1), a pneumatic cyclone unit(2), a washing in water Gravity separation tub(3), an extrusion unit(4), boiler(5). A grinding unit forms a grinding box(100). The grinding box forms a first and a second grinding blade(102,103) at the inside of the grinding chamber and a filter discharge compartment(104) at the lower part of the grinding chamber. A filter(105) is mounted which a filter hole(105a) between a grinding chamber and a filter discharge compartment is formed. A exhaust tube(106) is formed to one side of the filter chamber main wall, a blower(107) is installed inside the exhaust tube. The pneumatic cyclone unit includes a division box(200). A insert hole is formed on upper side of a division box main wall, a upper side of the exhaust tube of a grinding box is connected. An exhaust tube(202) is formed vertically and is connected to a water tank in the center part of the roof of division box. A foreign material receiving part(203) is formed in the lower part of the division box and a drawer type exhaust vessel(204) is installed. The washing in water gravity separation tub is cylindrical type and is has a plurality of exhaust hole in the upper part of the top(301). An accepting chamber(300) installed a shower nozzle(303) and is formed the washing in water gravity separation tub. The accepting chamber forms a connection unit and is connected to an exhaust tube of the pneumatic cyclone part. A storing water chamber(304) is formed in the lower part of the accepting chamber and a transfer pipe(306) mounted to a screw outside the main wall is formed. A electric motor(307) drives a screw. The extrusion unit includes an insert hopper(400), a large diameter extruded tube(401), a screw(402,404), a small diameter extruded tube(403), a extrusion dice(405), an outer box(407,408). The insert hopper is connected with a transfer pipe of a water gravity separation tub. The large diameter extruded tube is formed to entrance side which an insert hopper is attached. A large screw is driven as the electric motor and is formed inside the large diameter extrusion tube. The small diameter extruded tube is formed exist side of the caliber extruded tube, a small screw is inserted. The extrusion dice is formed in the end of the small diameter extruded tube and open-and-close plate is mounted. A high pressure steam provided from a stream boiler as a outer tube is covered to outer circumference of the large diameter extruded tube and the small diameter extruded tube through supply tube(501). An electric open-and-close valve in mounted at an element of high steam supply tube and temperature sensor(S) is included in outer circumference of extruded tube. A storing water unit is formed in the entrance side floor of large diameter extrusion tube and attaches a connection tube(409) which an open-and-close value is mounted on outer circumference of drain hole by drilling the drain hole(401b). The connection tube supplied steam to extruded unit which is connected to a storing box(6).
