At present, PS plastic has excellent functions of heat preservation, heat insulation, buffering, shock resistance, water resistance and the like, and is widely applied to industries such as buildings, household appliances, instruments, foods, packaging and the like. However, the foamed plastic is often regarded as a disposable product, and is generally disposable due to low recycling value after use, so that white pollution is easily caused. And because the density of the plastic is low and the volume is large, great challenges are brought to each link of storage, transportation, treatment and the like of the waste plastic. At present, most of waste PS plastics in China are treated by landfill or incineration, the recovery rate is only about 30%, and environmental pollution and resource waste are easily caused. The existing foam melting treatment equipment usually exists in the form of a centralized treatment plant, but the existing foam melting treatment equipment is usually long in transportation distance, large in occupied area, large in volume and large in labor investment, and the transportation cost of the plastic is increased and the economical efficiency is poor for generating waste foam plastics in residential areas with scattered sources.

The foam plastic has huge recycling and regeneration potential, and although the technology of the current centralized foam plastic production line is relatively mature, the problems of high transportation cost, serious environmental pollution and the like exist. The defects of the current processing technology mainly comprise the following aspects: (1) The technical process of the large-scale treatment plant is too long, a large amount of land resources are required to be occupied for building the plant, and the labor cost is high; (2) The transportation distance is too far, the layout planning is difficult, and the method is not suitable for urban areas with deficient land resources; (3) The common large-scale treatment equipment adopts an open production process, is lack of waste gas treatment facilities and is easy to pollute the environment; (4) Generally, the broken particle size of the foam is large, and feeding is difficult in small single-screw extruder application; (5) The automation degree is low, the personnel operation is frequent, and higher labor cost needs to be invested. Therefore, the dispersed and high-integration foam plastic processing device has good development prospect in areas such as districts and streets with large population scale and large foam plastic consumption, and can effectively solve the problems of resource waste and environmental pollution of the foam plastic.

Based on this, the utility model discloses following embodiment provides a portable abandonment foamed plastic melting granulation regeneration facility, through integrating each module and automatic, makes into standard container formula's waste gas foamed plastic treatment facility to improve the mobility of equipment itself, greatly reduced area and the cost of labor of equipment itself, can satisfy different region's foamed plastic treatment demand and realize volume decrement maximize.
