Filed:

Apr 5, 2000

Appl. No.:

09/543726

Inventors:

Karl W. Schmidt - Commerce City CO 80022-2247

International Classification:

B07B 1307

US Classification:

209674, 209660, 209659, 209916, 209921, 209677

Abstract:

An apparatus and method for separating recyclable corrugated paper from a stream of commingled waste. Commingled waste is loaded onto a conveyor with two alternating sets of jogger beams. A motor drives the jogger beams out of phase with respect to one another causing the waste to fall between the jogger beams, while corrugated paper remains above and moves along the jogger beams, thereby separating the two components. Optionally, a second stage of jogger beams can be positioned forward of the conveyor to create a drop therebetween to further separate the commingled waste. The jogger beams are cantilevered beyond the motor so that waste falls clear of the motor.

US Classification:

209635, 209691

Abstract:

A conveyor system for separating mixed recycled materials containing lighter and heavier recycled materials employs an inclined conveyor belt with a series of rows of rotating beaters striking the underside of the conveyor belt. A feeder mechanism deposits mixed recycled materials onto the midsection of the conveyor belt. Heavier recycled materials are bounced from the conveyor belt and tumble to the lower end, while lighter recycled materials are carried by motion of the conveyor belt to its upper end.

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.
