Raw sewage disposal apparatus
First Claim
1. A raw sewage disposal apparatus comprising:
- a heat-resistant vessel for containing raw sewage therein;
a heating means for heating the vessel to thereby evaporate the liquid component of the raw sewage and dry the raw sewage in the vessel;
a stirring means having a plurality of stirring blades for stirring the raw sewage in the vessel;
a plurality of spherical heat-holding bodies contained in the vessel;
an introduction pipe communicating with a side surface of the vessel;
a stool connected to an upper end of the introduction pipe;
a gear box mounted on the vessel and having a rotary shaft which rotates the stirring means;
a heating pipe which has a heater therein and communicates with a first air supply means at one open end thereof and with a catalyst box at the other open end thereof, said first air supply means comprising an air blower containing a motor and a fan driven by the motor;
a second air supply means communicating with the vessel for supplying fresh air into the vessel;
said catalyst box containing a catalyst therein and communicating with the second air supply means by way of an exhaust pipe and an ejector, said catalyst being heated by the heater in the heating pipe;
an air introduction pipe communicating at one open end thereof with a side surface of the heating pipe, said air introduction pipe being branched into two pipes at an upper open end thereof;
a discharge pipe communicating at one open end thereof with the vessel for exhausting vapor formed by the evaporation of the liquid component of the raw sewage in the vessel, said discharge pipe communicating with one branched pipe of the air introduction pipe by way of a first closing valve;
a cleaning pipe communicating with the other end of the discharge pipe by way of a second closing valve;
a dust collector connected to the cleaning pipe; and
a return pipe communicating at one end thereof with the dust collector and communicating with the other branched pipe of the air introduction pipe by way of a third closing valve.

Abstract
A raw sewage disposal apparatus capable of evaporating the liquid component of raw sewage contained in an airtight vessel and capable of cleaning the vessel after and evaporating the liquid component of the raw sewage and heating the vessel so that dust which is not evaporated can be collected with assurance, hence the apparatus can be used for a long time. The apparatus comprises a vessel for containing the raw sewage therein, a heater for heating the lower portion of the vessel, an air supply pipe for supplying air into the vessel, a discharge pipe communicating with the vessel for discharging vapor formed by the evaporation of the liquid component for the raw sewage, a catalyst box connected to the discharge pipe by way of a closing valve, a dust collection box connected to the discharge pipe by way of a closing valve and a collection bag housed in the dust collection box for separating the dust from the air and collecting the dust.
