Patent ID: 8211378

Claim:
A reactor for separating aluminum from multi-layer film wastes, the reactor comprising: a casing filled with a solution for dissolving an aluminum layer of the multi-layer film materials pulverized into a predetermined size, the casing having a top, a bottom, and a center; one partition installed at one side of the casing, the partition having an arc shape and an upper end and a lower end, the upper end of the partition being positioned to extend above the solution filled in the casing, the partition dividing an inner portion of the casing into a reactor tub, which is installed at the center of the casing and in which the solution is reacted with the aluminum and in which the multi-layer film, wherein the aluminum layer has not completely being dissolved, can reside, and at least one separator tub that is provided at a side portion of the reactor tub to hold the multi-layer film materials in which the aluminum layer is completely dissolved by means of the solution; and a stirrer installed at an upper portion of the reactor tub for stirring the solution in the reactor tub in order to selectively transfer the multi-layer film materials, in which the aluminum layer is dissolved in the reactor tub, based on its difference in specific gravity, from the reactor tub to the separator tub; wherein the partition is angled toward the center between the top of the casing and the bottom of the casing such that the lower end of the partition is closer to the center than the upper end and the partition is spaced apart from a bottom of the casing by a predetermined distance to define a passage between the casing and the partition and the reactor tub is interconnected with the separator tub through the passage, and whereby the partition prevents the multi-layer film, selectively separated into the separator tub with the aluminum layer completely dissolved, from flowing into the reactor tub so that, due to the difference of specific gravity, the multi-layer films with aluminum remain in the reactor tub and the multi-layer films without aluminum remain in the separator tub; and whereby the arrangement of the partition in the casing induces a localized flow change of the multi-layer films for separation at the bottom of the casing.
