Cutting open used filter cartridges containing hydrocarbons and filtered pollutants, comprises use of reduction motor driving two wheels on plate

摘要

A reduction motor (4) drives two knurled wheels (3) on a plate (6) which drives the filter (7) in rotation against the load from a pneumatic jack (1) with a free circular knife (2) at its end to cut the filter at its base. The knife on the pneumatic jack is a can-opener type and provides the third point for holding the cartridge.
