Optimal control method of extinction manure treatment device {A OPTIMUM METHOD OF CONTROLLING EXTINCTION APPARATUS FOR FECES AND URINE IN THE TOILET}

The present invention relates to an optimal control method of the decay-type manure treatment device, and more particularly to the optimal fermentation conditions for the manure consisting of feces and urine stored in a simple toilet that is conveniently installed in a park, amusement park or resting place, rural areas, etc. The outside air is controlled to an optimal hot air temperature for the composition, and at the same time, the manure containing a large amount of water is dried at a high speed by using the hot air, but the manure treatment soil and the activated carbon containing local ingredients together with the manure. By stirring, the process of fermenting and drying the manure at the same time to process the manure at a high speed to the optimal control method of the decay-type manure treatment device that does not need to be reprocessed separately.

The manure processing device of the simple toilet in the very early stage is a large-scale manure processing device designated by transferring to the manure processing difference when the manure accumulated in the manure reaction part installed in the lower part of the simple toilet becomes more than a predetermined amount. As shown in the technology, by using the stirring blade 25 mounted on the outer periphery of the stirring shaft 24 installed in the manure reaction unit 21 to stir the integration with the manure at a low rotational speed slowly, The heater 22 is installed at the lower part of the manure reaction part 21 to provide fermentation temperature to the manure, and an exhaust fan 23 is provided at one side to stir the odor light to the outside. Fermentation temperature conditions were given to the aerobic organics of manure.

However, the control of the manure processing apparatus of the conventional simple toilet having the above-described configuration is very late in the fermentation time, especially the manure containing a lot of moisture such as urine is not dried, anaerobic decomposition is methane There are many problems, such as the generation of type microorganisms, severe odors, and the control method for the manure treatment device of the prior art was made by a relatively simple control method consisting of the control of the stirring shaft and the heater.

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, an object of the present invention is to provide a hot air having an optimal temperature conditions for manure fermentation to the manure and hot air transport to dry the manure using the hot air at the same time A control step; Manure stirring control step of providing the best stirring conditions to the manure in conjunction with the hot air control step; In particular, by including a urine treatment control step for processing the urine exclusively by the manure handling device quickly and hygienic An object of the present invention is to provide an optimal control method of an extinction manure treatment device that can be treated.

In order to achieve the above object, the present invention provides an optimal control method for the decay-type manure treatment device for decomposing and treating the manure into aerobic microorganisms, the optimal control method according to the invention is the fermentation conditions of aerobic microorganisms It is made to become a condition that, according to the optimum control method of the present invention is as follows.

The first is the particle size. In organic fermentation reaction, fermentation takes place on the surface of organic material, so the smaller the particles of organic material are, the faster the fermentation reaction rate is. Figure 2a is a schematic diagram showing the manure treatment promoting portion according to the present invention, the activated carbon (10) and the manure treatment soil (9) mixed with ocher and lime in a constant weight ratio therein, mixing with the manure by stirring At the same time, the manure is introduced into the manure passage opening 17 and mixed with the activated carbon 10 and the manure treating soil 9 to provide an optimum particle size for fermentation and culture of aerobic microorganisms. .

Figure 2b is a schematic view showing a protective pail according to the present invention, the activated carbon 10 and the manure treatment soil (9) constituting the manure treatment facilitating unit (11) is easily broken while stirring mixed with a stirring blade In order to prevent damage to the configuration, etc., and further, a plurality of manure passage openings 17 formed on the surface of the protective pail 18 is provided so that the manure is adsorbed with the activated carbon 10 and the manure treating soil 9. It is configured to be.

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 Figure 2a, the manure treatment soil (9) contained in the manure treatment promoting portion 11 of the present invention contains the water of the urine fecal while mixed with the local soil and lime in a constant weight ratio It is configured to function to discharge the water contained as needed, and also provides a function to allow the aerobic microorganisms to be cultured and active inside the manure treatment soil (9). 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 10wt% to 30wt%. Here, the mixed weight ratio of the local soil and the lime of the manure treatment soil 9 is mixed with the porosity and the manure therein to simultaneously meet the external configuration for maintaining the shape, the lime exceeds 30wt% or more This is because the voids of the manure treatment soil 9 become very dense, and the function of containing water is drastically lowered, and the function of culturing aerobic microorganisms in the interior becomes remarkable.

The third is oxygen, which requires oxygen to oxidize carbon in aerobic microorganisms to obtain energy (aerobic decomposition), making carbon dioxide and water as end products. Oxygen-free fermentation is possible, but the fermentation is very slow, anaerobic and odor is generated. 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 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 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. In addition, in order to increase the surface area of the organic matter and to reduce the odor generated during the fermentation it will be a preferred embodiment to add the sawdust together with the manure treatment soil (9) and activated carbon (10).

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 feature of the control method of the present invention is to supply external air to the heater to the blower, to provide the 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 Is in. To this end, a temperature sensor for sensing the temperature of the hot air flowing out of the outlet 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 more than 60 ℃. In addition, the hot air is intended to dry by forced convection of manure containing a large amount of moisture at the same time as fermentation at high speed.

The extinction type manure treatment apparatus for achieving the control method according to the present invention for processing the fermentation and drying of the aerobic microorganisms described above at high speed will be described with reference to FIGS. 3 and 4.

A stirring shaft 1 which is rolled up inside the manure reaction section 8 and rotates; A plurality of stirring blades (2) rotatably mounted on the outer periphery of the stirring shaft (1); The stirring blade (2) can be rotated, to provide a space for filling the manure, but the upper side of the hot air of the hot air heated by the heater (4) can be supplied by the blower (3) A manure reaction section (8) consisting of a manure storage section (6) provided to store manure at the bottom of the hot wind acid base (5) provided with two passages; An exhaust fan 12 installed in an exhaust passage provided at one side of the manure reaction part 8 to discharge odors to the outside; The manure reaction part (8) is filled with manure and stirred, but the manure treatment soil (9) and activated carbon (10) formed by mixing the loess and lime are contained therein and the outer surface of the plurality of manure passage opening (17) (3) is provided with a manure treatment promoting unit 11, and is an extinction type manure processing device composed of a configuration that does not require reprocessing by eliminating the manure by evaporating and fermenting the organic matter and moisture of the manure at high speed.

In addition, the separate extinction type manure processing apparatus for achieving the control method according to the present invention separately formed on one side of the manure reaction unit 8, the urine storage unit 15 for exclusively processing the urine as shown in FIG. It is to be configured in conjunction with the manure reaction unit (8).

One side of the urine storage unit is provided with a water level detection unit 14 for detecting the water level of the urine, the water level detection unit is configured to be connected to the urine transfer pump 13 for pumping the urine storage unit 15 The urine volume of the urine is made to pump urine to the manure reaction section (8). The pumped urine is mixed and stirred and fermented with the manure treatment promotion unit 11 in the manure reaction unit 8 and dried and processed by hot air at the same time.

In addition, the humidity sensor 16 is mounted on one side of the manure reaction part 8 so that the urine transfer pump 13 operates when the humidity is lower than the urine storage part 15 so that the urine storage part 15 8) is configured to be pumped.

5 is a flow chart illustrating a control method of the decay type manure treatment device according to the present invention is configured as follows. In the initial stage, when a person enters the manure processing device, an indoor light is turned on, and an exhaust fan operation control step of operating the exhaust fan 12; When the person goes out, the interior light is turned off, the exhaust fan continues to operate for a predetermined time, the operation is stopped, and the operation of the heater (4) and the blower (3) starts at the same time as the person exits the blower (3) Hot air transfer control step of transferring the hot air heated by the heater (4) by the manure reaction unit (8); At the same time as the hot air transfer control step, the stirring shaft 1 operates at a constant rotational speed to stir together the manure, the manure processing soil 9 and the manure processing facilitator 11 containing activated carbon together. It consists of an optimal control method of the decay-type manure treatment device, characterized in that it comprises a step.

In the hot air transfer control step, the temperature sensor for detecting the temperature of the hot air flowing out to the outlet side of the heater 4, the operation of the heater 4 is stopped when the temperature of the hot air is 60 ℃ or more, but the blower (3) ) Is controlled to continue, which is a temperature control for forming the internal temperature condition of the manure reaction section 8 as the optimum fermentation condition because the optimum temperature condition of the aerobic fermentation is 40 ℃ to 60 ℃. In addition, the temperature control step as described above will consume unnecessary power when the manure is not stored in the manure reaction unit 8 because there are relatively few people entering the toilet with the manure treatment device. In this case, it is intended to control the fermentation temperature and reduce unnecessary power consumption by installing a configuration such as a timer to control the heater 4 so that the heater ON operation and the heater OFF operation are repeated at regular time intervals. For example, it provides timer control to selectively adjust the operating time of the heater, such as 30 minutes ON / 30 minutes OFF or 10 minutes ON / 50 minutes OFF.

In the manure agitation control step of the present invention, it is preferable to control the rotational speed of the stirring shaft 1 soaked in the manure reaction part 8 to rotate 1 to 2 per 10 minutes. This is because excessive stirring speed accelerates the evaporation of the manure too much, and there is not enough time for the aerobic bacteria to be cultured and fermented.

Another control feature of the present invention, the urine-only treatment of the decaying manure treatment apparatus is roughly divided into two control methods as shown in Figs. The first is a control to process urine by the water level signal of the urine volume of the urine storage unit 15. In detail, the water level detecting unit 14 is configured to adopt a configuration to detect the small variable position electronically to perform the operation required for the selective configuration, the water level detecting unit 14 for the control according to the present invention The urine transfer pump 13 is configured to be connected with the operation of the urine transfer pump 13 to detect the level of the urine amount detected by the water level detection unit 14 above a certain level. (8) is the urine processing control step.

The second is the control to process the urine by the signal of the humidity sensor 16 is formed on one side of the manure reaction unit (8). It is configured to operate the urine transfer pump 13 in response to the signal of the humidity sensor 16 so that the urine transfer pump 13 when the humidity detected by the humidity sensor 16 of the manure reaction unit is below a predetermined humidity It is operated to the urine treatment control step to transfer to the manure reaction section (8). Here, the preferred humidity control signal is that the humidity is 80% or less, because the proper fermentation conditions of the aerobic bacteria in the manure reaction section 8 is 60% to 80%.

As such, the water content of the urine pumped from the urine storage unit 15 to the manure reaction unit 8 is usually 93% to 97%, and in the manure reaction unit 8 by the hot air of the hot air transfer control step. By supplementing the insufficient amount of water that can be formed to provide sufficient moisture to the feces and urine mixed manure of the manure reaction unit 8 to provide a continuous fermentation conditions of aerobic bacteria, and furthermore, There are many advantages of being easily dried and treated as forced convection of hot air.

The hot air transfer control step, the manure stirring control step, the urine treatment control step of the extinction type manure treatment device is started as soon as the person goes out, if the person enters the toilet again while the operation is in progress to stop the operation of the steps And, it is preferable to control the room light to be turned on again and the exhaust fan 12 is returned to the initial stage, which is an exhaust fan operation control step in which the exhaust fan 12 is operated again. This is because when the person is in the bathroom, the hot air transfer control step, the manure agitation control step, and the urine treatment control step operate to make the person in the bathroom feel anxiety and odor. Therefore, the operation of the decaying manure treatment device is usually performed at night, and the continuous operation for about 10 hours can completely sanitize the manure in the manure reaction section (8).

The present invention configured and operated as described above provides an optimal control method of the decay-type manure treatment device that is decomposed and treated as aerobic microorganisms, the control method is controlled so that the fermentation of aerobic microorganisms is an optimum condition, and At the same time, a method of controlling the drying to proceed together is to be provided. In addition, by using a large amount of water urine to provide the moisture required for the aerobic microorganism fermentation, and at the same time to provide a method for controlling to be forced to dry to the atmosphere, feces as a device without any other manure treatment device It is to provide an optimal control method of the decay-type manure treatment device capable of treating the urine and urine at a high speed and hygiene.
