Degreasing and dry deburring machine with a suction system, and associated method

A dry degreasing and deburring machine comprising:

• a rotating treatment tank designed to receive at least one workpiece, an absorbent medium and an abrasive medium, the treatment tank being provided with orifices allowing the evacuation of dust and debris from a treatment out from the treatment tank,
• a suction channel to remove dust and debris,
• the treatment tank and the suction channel being arranged in a treatment chamber,
• wherein the dry degreasing and deburring machine comprises a suction system being connected to the suction channel, said suction system comprising:
• an air suction circuit,
• a suction fan,
• a settling chamber equipped with a filter cartridge,
• an unclogging unit provided for injecting an unclogging air flow into the filter cartridge during an unclogging operation,
• a control unit which controls the fan and the unclogging unit as a function of pressure and load measurements in the air suction circuit,
• wherein an upstream filtration unit is arranged upstream of the settling chamber, said upstream filtration unit comprising a removable drawer whose bottom is provided with a filtering grid intended to retain reusable particles of the absorbent medium, so as to allow a user to recover the reusable particles of the absorbent medium by means of the drawer and then to discharge them into the treatment tank.
