Description

Recycled oil filter { APPARATUS FOR FILTERING RECYCLED OIL }

The present invention relates to a filtering device. More specifically, it relates to a reclaimed oil filtration device.

In general, as the amount of plastic and vinyl increases, the amount of waste plastic and vinyl continues to increase, and landfilling of waste plastic or vinyl causes serious environmental pollution. An emulsification facility has been developed to emulsify waste plastic and waste vinyl for use.

By the way, in order to emulsify waste plastic or waste vinyl through an emulsification facility, waste plastic or waste vinyl is heated or cooled, and at this time, recycled oil is produced, which may contain a lot of foreign substances such as dust and tar.

Therefore, the reclaimed oil cannot be used immediately, so its use value is low, and in order to use it as reclaimed oil, foreign substances contained in the reclaimed oil must be removed.
