[0002]
[Prior art]
Mobile unit toilets temporarily set up at construction sites and civil engineering sites, etc., in places where there are no sewage or water facilities, a storage-type toilet tank is provided under the floor where toilets are placed, and the toilets are surrounded as small rooms. Since the toilet tank is a storage type, it cannot be used when the toilet tank is full, so it needs to be pumped, or the urine collected from the unit is taken out and emptied and emptied again. There was a need to bring it into. Moreover, the mobile unit toilet temporarily installed in the place where the sewage and the water supply are installed is of a type in which the unit is equipped with a flush toilet and a pipe through which the urine from the toilet is discharged to the sewage outlet. The former mobile unit toilet could not be used when the toilet bowl was full, and it had a strong bad odor, which unpleasantly smelled not only in the toilet but also around it. The latter flush-type mobile unit toilet is clean, but there is a problem that it can only be installed in places where sewage and water are provided.
[0003]
Therefore, the applicant of the present application solves the problems of the above-mentioned conventional mobile unit toilet, can be used even in places without sewage and water facilities, has no foul odor, and does not fill up the treatment tank. Developed a vaporizing mobile unit vaporizing toilet that eliminates the need for pumping and does not require replacement for each unit, and that is clean and less uncomfortable even under hot summer heat (for example, see Patent Document 1) ).
[0004]
This mobile unit vaporizing toilet has a double wall consisting of an outer wall and an inner wall around the toilet building at the upper part of the toilet. However, it is possible to store a larger amount of water for rinsing than this, and to move the structure so that it can be installed stably without falling down even if blown by a strong wind. There is a need for a type-unit vaporizing toilet. Furthermore, this mobile unit vaporizing toilet supplies air by blowing air into the treatment tank of the stool and decomposes the organic matter of stool urine into water, nitrogen, hydrogen and carbon dioxide by aerobic microorganisms, while stirring the air and Heating is performed by a heater provided to evaporate and evaporate the water, nitrogen, hydrogen, and carbon dioxide generated by the above decomposition, but bubbles are generated in the filth layer in the treatment tank by air agitation. As a result, the surface of the stool layer of feces and urine is covered with the foam, and as a result, the supply of air to the surface of the stool layer may be blocked, and the aerobic microorganism activity may be inhibited. .

It is a mobile unit vaporization toilet of the means of any one of 1-4.
[0016]
The operation of the present invention will be described. In the mobile unit vaporizing toilet of the present invention, in the means of the invention of claim 1, the lower part of the stool urine treatment tank is partitioned by a partition, and is formed of two tanks, a primary treatment tank and a vaporization tank. Yes. These partition walls are partition walls and serve as support walls that support the side walls of the stool processing tank. Furthermore, the upper part of the partition wall is not closed between the primary treatment tank and the vaporization tank, and air flows and the gas in the primary treatment tank and the vaporization tank can be exhausted from the primary treatment tank through the exhaust pipe. The primary treatment tank is a tank that first receives the feces and urine excreted from the flush toilet of the light water flush and flush water. Here, light water washing is not water washing by flowing a large amount of water as usual, but means water washing in which a small amount of 250 cc of water is used to pass defecation and urination from a toilet bowl to a toilet bowl. At the bottom of the primary treatment tank, there is an annular air ejection pipe with a diffuser port consisting of many small holes that ejects air to sewage urine, and a central air ejection pipe arranged at the annular center position. Then, air is sent from each of the blower chambers on the side of the stool urine processing tank to these air ejection pipes, and the filth is agitated, while the primary of the blower chamber provided on the side of the stool urine processing tank An elbow type air supply pipe is provided on the filth layer of the primary treatment tank from a fan provided on the side wall on the treatment tank side, and air is supplied from the opening to the surface of the filth layer. Further, an annular electric heater is provided in the filth layer so as to be spaced above the annular air ejection pipe, and the filth is heated to room temperature. Therefore, the activity of aerobic microorganisms mixed from the atmosphere in the stool urine waste in the primary treatment tank is activated by air agitation and moderate heating, and the stool sewage is primarily decomposed by this activity, and the Part is changed to nitrate and hydrogen, nitrogen, carbon dioxide or water. These generated gases produce bubbles in sewage containing nitrate.
[0017]
By the way, the air ejection pipe is an annular air ejection pipe so that the ejection air can be uniformly diffused in the filth, and the air diffuser port through which the air is ejected has a large number of small openings. Therefore, the fine air ejected from the air diffuser of the annular air ejection pipe forms a large number of bubbles and covers the surface of the filth tank. When the surface is completely covered with bubbles in this way, air containing fresh oxygen cannot contact the surface of the filth layer. Therefore, in the invention of the present application, a central air ejection pipe having a large opening and ejecting air as a large bubble is provided at the center of the annular air ejection pipe having a diffuser port for ejecting small air, and the air is ejected from the central air ejection pipe. The above-mentioned small bubbles are removed with a large bubble so that the surface of the filth layer can be brought into contact with the air blown out from above. Further, the gas generated in the primary treatment tank is external to the toilet building from the exhaust pipe standing on the floor of the toilet room above the primary treatment tank together with the gas generated in the vaporization tank flowing in through the upper part of the partition wall. Exhausted.
[0018]
The water generated by the primary decomposition of the sewage becomes partially sewage containing undecomposed nitrate, and the toilet in the primary decomposition tank passes through the overflow pipe provided in the upper part of the partition wall from the upper part of the primary treatment tank. Sent together with undegraded coarse impurities such as paper. The coarse contaminants are passed through a bag-like filtration net attached to the outlet of the overflow pipe, the coarse contaminants are trapped, and the sewage from which the coarse contaminants are removed is stored in the vaporization tank. The sewage containing nitrate accumulated at a certain level below the inlet of the bag-shaped filtration net is heated to room temperature, which is the optimum temperature at which aerobic microorganisms are most active, by an electric heater disposed at the bottom of the vaporization tank. Therefore, both the annular electric heater of the primary treatment tank and the electric heater of the vaporization tank are temperature controlled so as not to be overheated by the thermostat as appropriate. In the same manner as above, an elbow type air supply pipe from the fan provided on the side wall of the blower chamber is disposed on the sewage layer of the vaporization tank, and air is supplied from the opening to the surface of the sewage layer, and contained in the sewage layer. The undecomposed nitrate and organic matter are secondarily decomposed and completely decomposed into gas such as water, nitrogen, hydrogen, carbon dioxide and vaporized. The water produced by the decomposition is also evaporated by heating with an electric heater. This decomposed and generated gas and the vaporized gas are exhausted from the above-described partition wall through an exhaust pipe that is inhaled by an exhaust fan installed in a toilet room above the primary treatment tank. In this way, the sewage treated in the vaporization tank is stable without increasing, usually only having a certain amount of sewage collected at the bottom of the tank. Therefore, this mobile unit vaporized toilet does not need to be pumped and does not need to be connected to sewage.
[0019]
In the means of the invention of claim 2, in the means of claim 1, the vaporizing tank is provided with an annular groove at the bottom, and an annular electric heater is disposed in the annular groove. Sewage water and decomposed water will be stored. Accordingly, in a vaporization tank composed of a normal flat tank bottom, when the amount of sewage stored in the tank bottom decreases, the water level drops and the annular electric heater is exposed, and secondary decomposition and transpiration cannot be continued. However, in the case of having the annular groove of the present invention, even if there is little sewage, the small amount of sewage is stored in the annular groove, so that the water level in the storage part of this annular groove is sufficiently ensured. The heater can be sufficiently submerged in the sewage, and secondary decomposition and transpiration can be safely and sufficiently performed.
[0020]
In the means of the invention of claim 3, in the means of claim 1 or 2, the lower part of the side portion of the stool processing tank is a water storage tank for storing water for washing, and the upper part thereof is a blower chamber. The mobile unit vaporizing toilet can be made compact.
[0021]
In the means of the invention of claim 4, in the means of any one of claims 1 to 3, the water storage tank for storing the water for washing contains a component for increasing the hardness of the water for washing to hard water. Since the washing water that flowed together with the feces and urine from the flush toilet is hard water, it suppresses the generation of bubbles caused by the air spouted into the filth layer of the primary treatment tank or the vaporization tank, By supplying fresh air from the surface of the filth layer without always covering the surface of the filth layer with bubbles, the activity of aerobic microorganisms can be activated and the decomposition of the filth can be improved.
[0022]
Further, according to the means of the invention of claim 5, in the means of any one of claims 1 to 4, a part of a water storage tank for storing water for washing is disposed at the lower part of the rear part of the vaporization tank, and the water storage tank A bag-shaped filtration net is used in which the area having the top surface of the top wall at the bottom is a void part integrated with the vaporization tank, and the top wall on the bottom surface of the void part is disposed at the outlet of the overflow pipe. The coarse impurities are taken out and the used filtration net is used as a drying shelf, and the dried filtration net can be used again.

[0024]
The mobile unit vaporizing toilet 1 of the present invention has a toilet room 2 composed of a toilet building 3 standing on the upper part of a stool / urine treatment tank 4, and a flush toilet 8 is installed on a floor 6 in the toilet room 2. . A stool urine treatment tank 4 is provided under the floor 6, and the stool urine treatment tank 4 is integrated with the toilet room building 3 thereon and installed on the ground. A stairway 7 to the door 5 of the toilet room 2 is provided in front of the stool / urine treatment tank 4. The lower half of the stool / urine treatment tank 4 is separated into two front and rear tanks by a partition wall 13, and the front tank is a primary treatment tank 14 for receiving the urine and flush water from the flush toilet 8, and the rear side, that is, FIG. The left tank is referred to as a vaporization tank 15.
[0025]
Further, a water storage tank 11 for storing water for washing is disposed around the fecal urine treatment tank 4 under the floor of the toilet room 2. The flush water is supplied from the water storage tank 11 to the flush toilet 8 through a pipe (not shown) by a pump, and the flush water is ejected into the flush toilet 8 by stepping on the flush pedal 9 appropriately.
[0026]
The flush toilet 8 is provided with an unillustrated toilet flush pipe (not shown) under the floor 6 for dropping feces and urine and flush water in the primary treatment tank 14. An overflow pipe 29 that leads from the primary treatment tank 14 to the vaporization tank 15 is provided above the partition wall 13 of the fecal urine treatment tank 4. A water storage tank 11 is provided below the stairs 7. On the other hand, a blower chamber 12 is provided on the upper side of the side of the stool processing tank 4. In the embodiment of the invention according to claim 3, the water storage tank 11 is similarly provided in the lower portion of the blower chamber 12. At the bottom of the primary treatment tank 14, an annular air jet pipe 16 having a number of air diffusing ports 17 downwardly communicating with the blower 21 of the blower chamber 12 by pipes is disposed. A central air ejection pipe 18 having an air ejection port 19 having a diameter larger than that of the air port 17 at the tip thereof is also arranged in communication with a pipe from the blower 21 of the blower chamber 12. FIG. 3 is an enlarged view of the central air ejection pipe 18 having an air ejection port 19 having a diameter of 35 mm at the tip and a base having a diameter of 13 mm. An annular electric heater 22 that heats the sewage 28 made of feces and urine water to room temperature at room temperature is disposed in the sewage layer 23 above the annular air jet pipe 16 and above. Thus, the reason that the air outlet 19 of the central air outlet pipe 18 has a larger diameter than the air outlet 17 of the annular air outlet 16 is that the fine air bubbles ejected from the air outlet 17 are the filth layer 23. In order to prevent the soil layer surface 27 from coming into contact with air and covering the entire surface of the soil layer surface 27 while agitating the aerobic microorganisms in the soil layer 23, This is because large air bubbles are blown into the filth layer 23 from the air outlet 19 to eliminate the fine air bubbles.
[0027]
Further, in order to supply air onto the filth layer surface 27 of the primary treatment tank 14, an elbow type air supply pipe 24 opened on the filth layer surface 27 is connected to a fan 26 provided on the side wall 25 of the blower chamber 12, Air is supplied into the filth layer 23, and air is supplied to the aerobic microorganisms in the filth layer 23 and activated together with the stirring air ejected from the annular air jet pipe 16 and the central air jet pipe 18 to primarily decompose the filth 28. Thus, a sewage 32 containing nitrate and a gas composed of hydrogen, nitrogen and carbon dioxide are used. In the embodiment shown in FIG. 1, there are two air supply pipes 24 opened on the soil layer surface 27. The elbow air supply pipe 24 is a PVC pipe having a diameter of 100 mm.
[0028]
The partition wall flows into the overflow pipe 29 from the overflow port 30 on the primary treatment tank 14 side, and the sewage 32 flows into the vaporization tank 15 from the outlet 31 of the overflow pipe 29. A bag-like filtration net 45 is suspended at the outlet 31 of the overflow pipe 29 of the vaporization tank 15 to remove coarse impurities such as undecomposed toilet paper contained in the sewage 32. An annular electric heater 35 for heating the sewage 32 to room temperature is disposed at the bottom of the vaporization tank 15.
[0029]
In the embodiment of the invention according to claim 2, the vaporizing tank 15 is provided with an annular groove 37 at the bottom. The annular groove 37 is used as a sewage 32 containing nitrate and a storage part 38 for decomposed water, and an annular electric heater 35 is disposed in the storage part 38 of the annular groove 37 so that the sewage in the storage part 38 is stored. Is heated to room temperature. In addition, the power supplies, such as the blower 21 of this invention, the fan 26, and the cyclic | annular electric heaters 22 and 35, shall be drawn in from the vicinity of an installation place suitably. Moreover, it is also possible to provide a photovoltaic power generation plate on the roof or side wall of the toilet building 3 to generate power and supply it.
[0030]
Further, similarly to the primary treatment tank 14, the vaporization tank 15 is provided with an elbow type air supply pipe 24 that opens on the sewage layer surface 34 from a fan 26 provided on the side wall 25 of the blower chamber 12. Then, air is supplied into the sewage layer 33, and the sewage 32 is decomposed by aerobic microorganisms to form a gas composed of water, hydrogen, nitrogen and carbon dioxide. The obtained water is heated to room temperature by the annular electric heater 35 and gradually evaporated to reduce its amount. The elbow air supply pipe 24 is a PVC pipe having a diameter of 100 mm.
[0031]
Further, the obtained gas is exhausted by an exhaust fan (not shown) built in the exhaust pipe 36 outside the toilet building 3 by an exhaust pipe 36 standing on the floor 6 which is the top plate of the vaporization tank 15. The upper part of the partition wall 13 between the primary treatment tank 14 and the vaporization tank 15 is opened to both tanks, and the air in both tanks can circulate. Therefore, the gas in the primary treatment tank 14 is an exhaust pipe standing upright in the vaporization tank 15. 36 is exhausted. As shown in FIG. 4, a louver 40 for taking air into the blower chamber 12 is provided on the side wall of the blower chamber 12.
[0032]

[0038]
【The invention's effect】
As described above, the mobile unit vaporizing toilet of the present invention is a mobile temporary toilet, but always comes from a flush toilet in a stool urine treatment tank without requiring sewage or water. Since stool such as feces and urine is decomposed into aerobic microorganisms and vaporized as hydrogen, nitrogen, carbon dioxide gas and water, etc., there is no bad odor and it always evaporates. A water storage tank for storing irrigation water is installed, so that the center of gravity is located below even if it is blown by strong winds, so it does not fall down easily, and the air jet blows air into the stool layer of the stool The tube also blows out fine air bubbles from the fine air diffuser and sufficiently applies air to the filth to make the activity of the aerobic microorganism suitable, and the entire surface of the filth layer is covered with this fine air bubble, The surface of the waste tank is less likely to come into contact with the air above it In order to prevent this, by arranging a central air jet pipe that blows out large air bubbles in the center, fine air bubbles are eliminated, and ore with hard water as the washing water is installed in the washing water reservoir By doing so, it is hard to produce foam by washing with hard water, and the activity of aerobic microorganisms is activated. Furthermore, in the vaporization tank, an annular groove is provided at the bottom of the vaporization tank, and this annular groove is used as a sewage storage part. Therefore, even if the amount of sewage in the vaporization tank is reduced, the electric heater works sufficiently in the storage part. Since the depth to be obtained is obtained, the present invention has an excellent effect that has not been achieved so far.
