Abstract
The discharge end portion of a sewage delivery tube is surrounded by the input end portion of a conveyor pipe. A long, flat strip of consumable filter material is inserted through the annular space between them and into the conveyor pipe. Prior to this insertion, however, the filter strip is shaped and fastened into the form of a closed tube. The conveyor pipe discharges into an incinerator equipped with means for breaking the sewage sludge into burnable droplets. The conveyor pipe is supported over a liquid-collecting funnel and is perforated in the portion thereof that is over the funnel. A vibrator attached to the conveyor pipe oscillates it longitudinally; and ratchet teeth inside the conveyor pipe are oriented to cooperate with the vibrator to urge the filter-encased sludge toward the incinerator.
Claims11
A waste treatment system comprising:
- a sewage delivery tube having a discharge end for introducing sewage into the system;
- a conveyor pipe having an input end and a discharge end and perforations in an intermediate zone thereof, the input end of which surrounds the discharge-end portion of the delivery tube with an annular space therebetween;
- a funnel positioned directly beneath the perforations to collect liquid from sewage;
- a long, flat, porous strip of consumable filter material, one end of which is inserted into the conveyor pipe around the sewage delivery tube;
- means for storing the filter strip;
- means for continuously forming the strip of filter material into a closed tube prior to its entry into the conveyor pipe;
- a vibrator attached to the conveyor pipe to oscillate it along the axis thereof;
- ratchet teeth inside the conveyor pipe oriented to urge the sludge-containing filter toward the discharge end thereof, when oscillated;
- and
- an incinerator in communication with the discharge end of the conveyor pipe to receive sludge therefrom, having a source of heat capable of burning sludge.
