On the other hand, when explaining the mechanical operation of the present invention. When the driving motor 60 is driven by the signal of the control unit 100, the stirring screw 40 connected to the reducer 61 is rotated and the excrement is stirred while being transferred in the longitudinal direction of the stirring screw 40.

At this time, oxygen is supplied into the stirring screw 40 and oxygen is uniformly supplied to the excrement through the ejection hole 43.

This process provides an optimal environment for aerobic microorganisms contained in sawdust, that is, an environment in which feces can be treated in a state in which the contact area of oxygen and microorganisms is uniformly increased throughout the feces. Will be maximized.

The waste treated as described above does not leave residues and the microorganisms in the saturated state treated with the waste are discharged to the outside through the discharge pipe 11 by the operation of the exhaust fan 12 connected to the outside.

As such, when the process of excretion is completely completed, the apparatus of the present invention stops operation to finish the final work.

In the series of operations described above, the operation is performed whenever the user leaves the toilet and the excretion may be treated at the time of use of the toilet, thereby eliminating the accumulation of the excreta.

In other words, if urine falls on top of the sawdust already contained in the tank, aerobic microorganisms inhabiting sawdust surround the urine and urine and increase it exponentially by feeding the urine and urine. When urine is fed by microorganisms, most of them are transformed into carbon dioxide (CO2) and water vapor by oxidative decomposition of microorganisms and are released to the outside through ventilation system.

Continuous oxygen supply is essential for the oxidative decomposition of the aerobic microorganism, and oxygen is supplied through the exhaust system and the oxygen generator according to the present invention.

In addition, the suction force is formed in the manure tank by the action of a powerful exhaust fan, the air is introduced into the manure tank through the air inlet and the toilet, and this air flow provides a continuous air supply and removes the smell in the bathroom.

In the case of feces, the amount decreases rapidly due to the oxidative decomposition activity of aerobic microorganisms in the manure tank, and after a certain time, most of the initial dose is denatured to water vapor and carbon dioxide.

On the other hand, the separated urine maintains the moisture necessary for the survival of aerobic microorganisms in sawdust, and like stool, it undergoes the oxidative decomposition of aerobic microorganisms and is denatured into steam carbon dioxide and a small amount of methane gas by fermentation heat. Is emitted to the outside through.

As described above, the present invention extends the contact area of the microorganisms in the process of transferring and stirring the excrement of the mobile ileus by a stirring screw to completely extinguish the solids of the excrement, thus eliminating the need for a separate excrement collection operation. It is possible to exclude the separate collection cost in the waste collection work to the toilet and to prevent inconvenience of the processing work.

At the same time, the present invention has the effect of improving the hygiene environment around the user by preventing the propagation of odors and pests of the summer removable toilet by keeping the internal clean state of the mobile toilet comfortably at all times.
