Description

Washing apparatus of plastic pieces

The present invention relates to a washing and separating apparatus for pulverizing the synthetic resin for washing the pulverized crushed plastic bottles.

In more detail,

Usually, a pulverized piece molded into a proper size by a predetermined pulverizer is put into a washing container filled with washing water by putting a container of a synthetic resin bottle molded of PET or PT into a washing container filled with washing water, and then pulverizing to the upper side of the washing water by buoyancy of the washing water. The grinding piece settles to the lower side of the piece and washing water. The washing is carried out while being transported by the lower feeder so that the crushed pieces washed while being transported to the upper side of the wash water are discharged by the floating crushed piece conveying device, and the crushed pieces that are precipitated and transported are collected from the lower side of the washing container. Collected and discharged to the outside of the washing tub to be transported to the next process, for example, the dehydration drying device of the crushed piece by a transfer conveyor.
