Method and apparatus for processing refuse, sewage and/or waste material into a source of energy. [mining wastes, municipal wastes, and sewage; materials recovery and briquetting of wastes for usable fuel]
This disclosure relates to a method and apparatus for handling refuse, using waste and treating raw sewage. The collected refuse is delivered to a receiving bin having an electrical vibrator and a power operated discharge door. The ferromagnetic articles are removed from the collected refuse by a magnetic separator. A shredder homogenizes the separated refuse, and acidic waste from a dispensing hopper is controllably mixed with the shredded refuse. The mixture of refuse and acidic waste is fed into a vertical rolling mill which dewaters and forms the refuse and waste mixture into briquettes. The briquettes from the rolling mill are dropped into a storage area which functions as a supply source from which briquettes are conveyed to a feeding trough. The briquettes of waste and refuse are controllably fed by the trough into a filtration tank to form a filtering bed. A supply conduit controllably delivers raw sewage effluence into the filtration tank so that the solids, matter in suspension and precipitates are entrapped by the filter bed medium. A level sensing device senses the amount of liquid in the tank, and a filter medium detector senses the depth of the filter bed so that expended filtering material is withdrawn from the tank by a power operated transport auger. The transport auger feeds an extruding mechanism which pelletizes the withdrawn expended filtering material. The pellets are conveyed to either a dispensing hopper or a pellet storage bin.The pellets are released from the pellet processing dispensing hopper and waste is also selectively and controllably released from the waste dispensing hopper. The mixture of pellets and waste is conveyed to the rolling mill for dewatering and for forming briquettes. The briquettes are fed to a storage area for subsequent use as a useable fuel. 32 claims, 3 drawing figures
