AN APPARATUS OF EXTINCTING FECES AND URINE IN THE TOILET}

The present invention relates to an extinction type manure treatment device, and more particularly, in order to create an optimal fermentation condition for the manure stored in a simple toilet that is conveniently installed in a park, an amusement park or a rest area, or a rural area. By controlling the hot air temperature and at the same time to dry the manure containing a large amount of water using the hot air at high speed, by stirring the manure treatment soil and activated carbon containing the local components with the manure, fermenting the manure and drying The present invention relates to a decay-type manure processing device that does not need to be reprocessed by processing the manure at high speed by simultaneously proceeding the process.

In general, when the amount of manure accumulated in the manure storage tank installed in the lower part of the simple toilet exceeds a certain amount, the manure is transferred to a manure processing differential to treat the manure in a designated large manure processing device. In order to simplify this inconvenience, the prior art of FIG. 1 uses a stirring blade 25 mounted on the outer circumference of the stirring shaft 24 installed in the manure reaction part 21 at a low rotational speed. It is a device for gradually fermenting and drying while increasing the fermentation area in contact with the outside air while stirring, furthermore, by mounting a heater 22 in the lower part of the manure reaction unit 21 fermentation temperature required for manure Provided, and the odor generated is discharged to the outside through the exhaust fan (23). In addition, in order to promote the fermentation of manure was introduced into a device for stirring with manure by inputting sawdust.

In general, the optimal fermentation conditions of feces and urine mixed with particle size, water content, oxygen, C / N ratio (carbon-to-nitrogen ratio), and temperature conditions should all be properly adjusted to the fermentation conditions of microorganisms.

However, since the manure processing apparatus of the conventional simple toilet having the configuration as described above is made so that only the temperature conditions are the optimum fermentation conditions of the organic matter, the manure treatment according to the prior art is very late in fermentation, and also, urine, etc. Manure, which has a high content of moisture, is not dried, and furthermore, there are many problems such as anaerobic decomposition, methane-type microorganisms are generated, and severe odors are generated.

In particular, the manure treatment accelerator such as sawdust is very weak in the external configuration as compared to the amount of solid and liquid manure as compared to the amount of sawdust filled in the prior art, because it is very easily dissolved in the manure to become a liquid state There is a problem that does not become a condition to provide, and if the amount of sawdust is less than the amount of the manure can be burned by a heater or hot air mounted on one side of the manure reaction portion 21, more important This includes many problems that the function of controlling the insufficient C / N ratio of manure to the optimal fermentation condition of 20% to 30% is also very weak.

The present invention has been invented to solve the above-mentioned conventional problems, and an object of the present invention is to provide a hot air having an optimal temperature condition and oxygen with which manure is fermented to the manure and at the same time use the hot air to make a lot of urine. Separate manure treatment by drying the manure such as agitated manure treated soil and activated carbon together with the manure to control the optimum water content and C / N ratio (carbon to nitrogen ratio) for aerobic microorganisms It is to provide an extinction type manure processing device that can treat the manure quickly and hygienically without the device.

Secondly, moisture content is very important for microorganisms as moisture content, fermentation rapidly decreases when humidity is below 30% ~ 40%, fermentation stops when below 30%, and proper fermentation humidity is 60% ~ 80%. However, when urine is mixed, it does not ferment much. In general, the water content of feces is 70% to 85%, the urine content is 93% to 97%. As shown in FIG. 2a, the manure processing soil 9 contained in the excreta treatment promoting portion 11 of the present invention contains water from the urine and the urine while lime is mixed and formed in a constant weight ratio. It is configured to function to discharge the moisture contained as needed, and also provides a function to allow the aerobic microorganisms to be cultured and active in the pores of the manure treatment soil (9).

Here, the mixing ratio of the native soil and lime of the manure treatment soil 9 is provided as follows to simultaneously meet the external configuration for maintaining the shape while stirring and mixing with the porosity and the manure therein.

As the mixed weight ratio of the native soil and the lime in the manure treatment soil 9, it is preferable that the native soil is 70wt% to 90wt%, and the lime is made of 10wt% to 30wt%. This means that when the lime exceeds 30wt% or more, the pore of the manure treatment soil 9 becomes very dense, and the function of containing water is drastically lowered, and also the function of culturing aerobic microorganisms in the interior is remarkably. Because it becomes.

The third is oxygen, which requires oxygen to oxidize carbon in aerobic microorganisms to obtain energy (aerobic decomposition), producing carbon dioxide and water as final products. Oxygen-free fermentation in the absence of oxygen is also possible, but fermentation is very slow and anaerobic, resulting in odors. In general, the natural fermentation method is not anaerobic fermentation method because the oxygen is not supplied. There is 21% oxygen in the air, the minimum amount of oxygen required by the aerobic fermentation microorganism is about 5%, the optimum amount of oxygen is more than 10% can be very active fermentation. The present invention is to provide the outside air to the aerobic microorganisms through the hot air fan surface using a blower.

Fourth, the C / N ratio (carbon-to-nitrogen ratio) is 20% to 30% suitable for fermentation conditions of aerobic microorganisms, but in general, the stool C / N ratio is 7% and the urine C / N ratio is 1%. It is known that the ratio of carbon is absolutely insufficient. It is a technical feature of the present invention to provide an apparatus for controlling such insufficient C / N ratio to the optimum fermentation conditions. As shown in FIG. 2A, the activated carbon 10 included in the manure treatment promotion unit 11 is mixed with the manure and stirred to adjust the insufficient C / N ratio of the manure to an optimal C / N ratio. It is configured to. Furthermore, since the plurality of activated carbons 10 contain respective surface areas, the activated carbon 10 is configured to increase the surface area of the organic material to increase the rate of organic fermentation reaction.

Fifth is the temperature, usually, the optimum temperature of the aerobic fermentation is 40 ℃ to 60 ℃, if maintained below 40 ℃ becomes a condition of anaerobic fermentation, if maintained above 60 ℃ pathogens are killed. Another technical feature of the present invention is to supply external air to the heater to the blower, to provide hot air adjusted to the optimum fermentation temperature in the heater to the inside of the manure reaction portion through the hot wind acid surface of the manure reaction portion to be a rapid fermentation. To this end, a temperature sensor for sensing the temperature of the hot air flowing out of the outlet end of the heater is provided, it is preferable to be configured to stop the operation of the heater when the temperature of the hot air is 60 ℃ or more. In addition, when there are not many people entering and leaving the toilet, it is desirable to install a timer that arbitrarily adjusts the operation (ON) and stop (OFF) of the heater to operate at a constant time period. For example, it may be desirable to reduce the operating time of the heater by setting the heater to 30 minutes ON / 30 minutes OFF, or to 10 minutes ON / 50 minutes OFF when no one enters or exits.

The configuration according to the present invention for treating the fermentation and drying of the aerobic microorganisms described above at high speed will be described with a schematic view showing an embodiment of the extinction manure treatment apparatus of FIGS. 3 and 6.

In general, the stool has a water content of 70% to 80%, the urine is 93% to 97%, the water content of the stool and urine is very high, the feces discharge per day 1 is 100g ~ 400g, urine 1.0Kg You're going to have a dose of ~ 1.3Kg. If you look at the maximum value of 1, the feces are 400g, and the urine is 1.3Kg,

Stool contains 60g of water and 340g of organic matter

Urine contains 1261 g of water and 39 g of organic matter.

As a daily maximum of 1700g per day, 1321g of water, 379g of organic matter and only 22% of organic matter, the organic matter is decomposed after removal of 78% of moisture, so the large amount of water is treated. It is one of the temporary features of the technical features of the present invention to provide an environment that sustains aerobic decomposition by providing a configuration that is solved as a high-speed evaporation using hot air.

Therefore, another technical feature of the present invention is to form a separate urine storage unit 15 for treating the urine containing a large amount of water as shown in FIG. It is to be configured in connection with the function of 8).
