ABSTRACT:
A recycling system processes used oil filters on a continuous basis by shredding the oil filters and then incinerating the shreds in a rotary kiln. The shreds are fed into the upper end of an inclined rotating drum kiln. The shreds of combustible material and any oil are burnt to produce exhaust gases and ash particles. The remaining metal shreds are discharged at the lower end of the rotating drum through a first port. The exhaust gases and ash particles flow from the kiln through a first cyclone which separates out any heavy unburnable pieces. The remaining exhaust gases and ash particles then pass through an afterburner to further ensure complete combustion and minimize air pollution. A second cyclone separates the ash particles from the exhaust gases. An exhauster can be used to induce the flow of exhaust gases and ash particles from the kiln through the afterburner and cyclones. This system automatically separates metal shreds and incinerates the combustible materials and oil in the oil filters. Ash particles are also automatically separated by the second cyclone and discharged through a separate port.
