Soil pump sewage handling system, method and toilet apparatus adapted therefor
Abstract
Abstract A sewage handling system, a toilet apparatus and a method by which waste may be pumped through a conduit of relatively small internal diameter. Heterogeneous mixtures of waste and flush fluid are emptied through a drain in the bowl portion of the toilet apparatus into a conically blending chamber therebeneath. Blade means are rotated at high speed within the blending chamber to transform the heterogeneous mixture into a homogeneous slurry that is easily transferred through the conduit into the holding tank by a pump means. A common motor drives both the blade means and the pump means, but in order to use a pump means that is low on power consumption some means must be employed to interrupt rotation of the blade means sufficiently to permit the homogeneous slurry to exit from the blending chamber and flood the intake off the pump means. In one embodiment of the invention disclosed this is accomplished by employing a clutch selectively to drive the blade means. Of particular suitability to this embodiment a baffle may be interposed between the blade means and the intake of the pump to minimize turbulence in proximity to the pump intake and thereby assure flooding of the pump intake even when rotation of the blade means is not absolutely precluded during the pumping stage of the flush cycle. In another embodiment a timing means deactivates the motor so as to interrupt rotation of the blade means for a predetermined time interval sufficient to permit the homogeneous slurry to pass from the blending chamber into the intake of the pump.
