초록 ▼

In general, used thermoplastic liquid containers such as oil and solvent bottles are discarded. When recycling oil bottles, the usual practice is to wash the bottles with a solvent to remove oil therefrom. Washing of the bottles results in large quantities of used, oil-containing solvent, which present a disposal problem. A simple solution to the problem of recycling liquid containers with no preliminary washing or cleaning operation includes the steps of tumbling the bottles to promote liquid separation, shredding the bottles into small pieces and draining the liquid therefrom, grinding the pieces of plastic to yield a particulate thermoplastic, and mixing the particulate thermoplastic and any liquid remaining therein with an additive, e.g. an oil absorbent and a filler such as calcium carbonate, glass, mica or talc, and when the liquid is an oil, an absorbent to produce an extrudable mixture which can be used to form new containers.

대표청구항 ▼

A method of recycling used thermoplastic containers having a liquid therein comprising the steps of: (a) separating some of the liquid from the thermoplastic by draining the liquid in the absence of any solvent in inclined tumbler means having an oil reservoir at the bottom thereof for collecting oil separated from the containers; (b) grinding the containers to produce thermoplastic particles with residual liquid therein; and (c) mixing said particles and residual liquid with an oil absorbent elastomeric additive necessary to absorb any residual oil and yield an extrudable mixture capable of forming new containers. An apparatus for recycling thermoplastic containers having a liquid therein comprising: (a) separator means for separating at least some of the liquid from the thermoplastic by draining in the absence of any solvent including tumbler means having an oil reservoir at the bottom thereof for collecting oil separated from the containers; (b) grinder means for receiving the thermoplastic from the separator means and for grinding the thermoplastic to yield a particulate thermoplastic with residual liquid therein; and (c) mixer means for receiving the thermoplastic from the grinder means and for mixing the thermoplastic and any residual liquid with an oil absorbent elastomeric additive to absorb any residual oil and produce an extrudable mixture capable of forming a new container.
