The present invention relates to a human waste treatment device equipped with an odorless evaporation mechanism.

[Conventional technology]

As a means of flushing toilets in areas where public sewage facilities are not fully equipped, for example, Japanese Patent Application Laid-Open No. 60-244392
A toilet purification device is described in the publication. Below, the third
This will be explained based on the figure. In the figure, (1) shows a toilet tank for domestic use, and this toilet tank (1) is connected to a flush toilet (3) through a human waste inflow pipe (2). It is connected to the. Human waste (8) flows into the toilet tank (1) together with washing water and is accumulated therein. (4) This is a manhole installed as a lid to cover the top opening of the toilet tank (1).
) with a large-diameter human waste discharge pipe (6) passing through it vertically,
A small diameter blower pipe (7) is fitted and fixed. The human waste discharge pipe (6) includes a first pipe part (6a) extending vertically downward from the insertion part of the manhole (4), and a first pipe part (6a) that is bent approximately horizontally above the insertion part. The lower part of the first pipe part (6a) is immersed in human waste (8) stored in the toilet tank (1). In addition, the second pipe part (6
b) extends vertically at its tip side and is connected in communication with an exhaust pipe (10) having an exhaust fan (9) at its upper end. On the other hand, the lower end of the ventilation pipe (7) extends vertically downward from the insertion part of the manhole (4),

The upper end of the blowing pipe (7) is bent approximately horizontally above the insertion part of the manhole (4), and is connected to a blowing means (13) comprised of a proa pump or the like. (5) shows a bacteria replenishment device, and human waste (8) stored in the toilet tank (1) is supplied with a predetermined amount of aerobic material from this bacteria replenishment device (5) at appropriate time intervals. Microorganisms, such as bacteria, are administered.

The purifying action of the conventional toilet purifying device having the above configuration will be explained below.

The human waste (8) sent into the toilet tank (1) is a bacteria replenisher! Due to the organic matter decomposition action of the bacteria administered from (5), it is decomposed into water (8,0) and carbon dioxide gas (CO,), which is simultaneously sterilized and the lower layer of sludge (8a
) and the upper layer of night soil (8b), forming a two-layered state. The liquid becomes a foamable liquid with high surface activity and flows into the foaming chamber (11). In this state, when air is blown into the foaming chamber (11) from the ventilation means (13) through the ventilation pipe (7), the foaming action of the foam generator (12) causes the foaming chamber (11) to
11) Stirring aeration is performed on the night soil fluid (8b). In this way, by supplying oxygen to bacteria, the night soil fluid (8b) is activated and foams.The bubbling of the night soil fluid (8b) causes water and carbon dioxide in the night soil fluid (8b) to be activated. becomes a group of bubbles (foam) and generates a bubble generator (
12) It accumulates above. These bubbles are sucked by the exhaust fan (9) and are exposed to the air flow in the process of rising inside the first pipe section (6a), gradually drying, and then passing through the second pipe section (6b). By the time it reaches the inside of the exhaust pipe (10), the water has almost completely evaporated and becomes an odorless gas, which is released into the atmosphere from the exhaust fan (9).

[Problem to be solved by the invention]

By using the toilet purification device shown in Figure 3,
It is understood that the night soil fluid (8b) is decomposed into water and carbon dioxide gas and released into the atmosphere as a gas. However, the ability of bacteria to decompose organic matter against the human waste (8) stored in the side layer (1) depends on the amount of evaporation of the human waste (8b) depending on the air temperature, the temperature of the washing water, or the air in the side layer (1). In reality, it varies considerably due to the influence of humidity, etc. For this reason, if the activation of the human waste fluid (8b) is insufficient, insufficiently dried air bubbles containing methane and ammonia will form in the human waste discharge pipe (6) due to incomplete decomposition of organic matter. flows into the exhaust pipe (10) from
There are few cases where it overflows from the upper end and contaminates the surrounding environment.Also, since stirring aeration is performed on the night soil (3b) accumulated in the toilet tank (1), the swirl created by stirring aeration Due to the flow of water, undecomposed toilet paper, etc. becomes liquid in the valve, and clogging of the pipe is unavoidable.Furthermore, the sludge (8a) accumulated in the side layer (1)
Human urine fluid (8b) had to be pumped out quite frequently, which was a major constraint in maintaining sanitary management.

A principal object of the present invention is to provide a solution to the above-mentioned problems observed in conventional gas-emitting toilet purifiers.

[Means to solve the problem]

As a means for achieving the above object, the present invention provides a toilet tank for storing human waste and washing water sent out via a defecation pipe, an auxiliary toilet tank connected to the toilet tank via a transfer pipe, and a first overflow tank. a re-foaming tank connected to the auxiliary toilet tank via a pipe; and a water seal pipe connected to the re-foaming tank via a second overflow pipe and connected to the toilet tank via a drain pipe. a first and second air supply pipe extending from the air supply device toward the toilet tank and the re-foaming tank; and a negative pressure suction type exhaust pipe extending from the auxiliary toilet tank and the re-foaming tank towards the exhaust fan. The distal end of the first air supply pipe is opened upward slightly below the liquid level of human waste within the lower end opening of the transfer pipe that opens downward into the toilet tank, and the A narrow cut groove extending in the axial direction of the transfer pipe is formed at the lower end of the transfer pipe opening into the toilet tank, and a large number of small holes are formed above the cut groove, and a number of small holes are formed above the cut groove. The height of the overflow surface of the first overflow pipe is set slightly downward from the upper end so that the highest liquid level of the urine fluid is maintained, and the tip of the second air supply pipe is set to the height of the re-foaming pipe. The lower end opening of the exhaust pipe that opens downward into the tank is opened upward slightly below the liquid level of human waste fluid, and the height of the overflow surface of the second overflow pipe is adjusted again. The liquid level of the human waste liquid in the foaming tank is set to be maintained slightly above the tip of the second air supply pipe, and the tip of the drain pipe is placed in the sewage water in the water seal tank. The object of the present invention is to provide a human waste treatment device in which the drain pipe is sealed and the overflow surface of the drain pipe is set slightly above the second overflow pipe.

Further, the above-mentioned human waste processing apparatus is configured in a double system, and in one toilet tank, the tip of the first air pipe of one human waste processing apparatus is connected to the tip of the first air pipe of the other human waste processing apparatus. The purpose of the present invention is to provide a human waste disposal device that opens upward by a predetermined amount.

[Effect]

By maintaining the liquid level of human waste collected in the feces tank slightly higher than the tip opening of the first air supply tube disposed in the lower end opening of the transfer tube, aerobic microorganisms, e.g. The night soil, which has been decomposed into water and carbon dioxide by the decomposition of organic matter by bacteria, is made into bubbles by the air jetted from the opening at the end of the first air pipe, and is ruptured as a sufficiently dry, odorless gas through the transfer pipe. After introducing it into the auxiliary toilet tank, it is discharged outside the system via the exhaust pipe and exhaust fan. On the other hand, if the number of people using flush toilets increases and the amount of human waste generated exceeds the processing capacity of the toilet tank, the human waste is temporarily transferred to the auxiliary toilet tank as sewage. After it has been stored, the human waste fluid is introduced into a re-foaming tank with the tip of the second air pipe opened upward slightly below the liquid level of the human waste fluid, and the second air pipe is opened upward. The air ejected from the opening causes the bubbles to burst, and is discharged as a sufficiently dry, odorless gas to the outside of the system via the exhaust pipe. If human waste is generated that exceeds the amount of re-foaming, the wastewater in the re-foaming tank is sequentially returned to the water seal tank and the toilet tank via the second overflow pipe and drain pipe.

4e), and the overflow surface is located slightly above the second overflow pipe (42).

Next, the operating state and functions of the device of the present invention will be explained. Stool flows down the defecation pipe (22)! The human waste (24) sent into (21) becomes water (Hz) due to the organic matter decomposition action of bacteria administered from the bacteria supply device (31).
The sludge is decomposed into O) and carbon dioxide gas (Cot), and separated into sterilized lower layer sludge (24a) and upper layer night soil (24b), which form a two-layered state and are stored in the toilet tank (21). be done.

The night soil fluid (24b) that remains above the toilet tank (21) becomes a foamy liquid with relatively high surface activity due to the decomposition of organic matter by bacteria, and flows into the lower end opening of the transfer pipe (26). . In this state, when air is blown into the lower end opening of the transfer tube (26) from the air blowing opening (27a) of the first air supply tube (27), human urine fluid (24b) that has flowed into the transfer tube (26) covers the air outlet (27a) of the first air supply pipe (27) in a thin film form, and is made into bubbles by the air ejected from the air outlet (27a), and the bubbles become larger over time. Eventually it will burst. That is, the thin film bubbles of night soil fluid (24b) whose main components are water (nzo) and carbon dioxide gas (CO), which have flowed into the vicinity of the tip of the first air supply pipe (27), are filled with continuous air. When the air bubbles are blown, they finally burst, and the water in the bubbles becomes a fine mist as a result of this bursting, and the air supply bag!
(30) and the negative pressure suction force of the exhaust fan (38) pass through the transfer pipe (27) to the auxiliary toilet tank (2
8) Sent within. This gas is supplied by an air supply device (
30) is pushed down by the air lift force and human urine fluid (
Transfer pipe (26) where the liquid level (L2) of 24c) is decreasing
The lower end of the third pipe part (26c) passes through the cut grooves (26d) (26d), which function as exhaust passages, and the small holes (26e), (26e), and the auxiliary toilet tank (28
), then flows into the exhaust pipe (36) via the branch pipe (39), and is dried by air lift and negative pressure suction before being dried by the exhaust fan (38
) is discharged from the system as an odorless gas that does not contain harmful gases such as methane and ammonia. When discharging this gas out of the system, the air lift force of the air supply device (30) depends much more than the negative pressure suction force of the exhaust fan (38). In addition, by passing through the cut grooves (26d) (26d) and the small holes (26e), the air bubbles are dispersed and a sound damping effect can be obtained.

In addition, in the case of a standard family structure (approximately 3 to 5 people), the amount of human waste (24) and washing water flowing into the toilet tank (21), and the amount of human waste flowing from the exhaust pipe (36). Since the amount of evaporation and diffusion of (24b) is substantially balanced, the liquid level (L,) of human waste fluid (24b) in the fecal tank (21) can be maintained at a substantially constant level.

On the other hand, due to some circumstances (for example, due to a significant increase in the number of people using flush toilets), human waste (
24) and when the balance between the inflow of washing water and the amount of evaporation and diffusion of human waste (24b) is lost, the ability of bacteria to decompose organic matter decreases, and untreated human waste flows from the toilet tank (21). There is a risk that the liquid (24b) may overflow or harmful gases may be discharged from the exhaust fan (38). The auxiliary toilet tank (2 days) is like this 5i! 5 Transfer pipe (26
) The condensed components of human urine fluid (24b) sent out in the form of bubbles are stored as waste water (24c).

Due to the defecation of a large number of people who differ from the preset usage conditions, human waste (2
4b) further increases, and the liquid level (L2) of the sewage (24c) that has accumulated as dew water in the auxiliary toilet tank (28)
When reaches the upper limit of the set liquid level, the waste water (24c)
through the overflow pipe (40) to the re-foaming tank (3).
4) Flow into the interior. Then, when the liquid level (L,) of the wastewater (24d) that has flowed into the re-foaming tank (34) rises to the set liquid level, the wastewater (24d) flows through the tip opening (37a) of the second air pipe (37). is covered with a thin film, and the tip opening (37a)
The bubbles are formed by the air ejected from the air bubbles, which grow larger over time and eventually burst. The bursting evaporates a fine mist of gas, which is sucked under negative pressure by the exhaust fan (38). It is then discharged out of the system as an odorless gas. On the other hand, when the liquid level of the wastewater (24d) that has flowed into the re-foaming tank (34) reaches the upper limit of the set liquid level,
Sewage (24d) is transferred to the second overflow pipe (42)
It flows into the water seal tank (41) through the water seal tank (41), and further flows into the water seal tank (41).
1) When the liquid level (L4) of the sewage (24e) that has flowed into the tank reaches the upper limit of the set liquid level, the sewage (24e) flows back into the toilet tank (21) through the drain pipe (43).

〔Effect of the invention〕

According to the present invention, since the liquid level of human waste in the toilet tank is maintained at a substantially constant level, there is no need to periodically pump out human waste. Therefore, it is possible to flush toilets even in areas without complete sewage facilities, and flush toilets can be installed by simply removing a small amount of sludge that has accumulated at the bottom of the toilet tank once every 1 to 3 years. Able to regularly use a sanitary toilet. Furthermore, since the gas discharged from the exhaust fan does not contain any harmful substances and is completely odorless, it can also exhibit remarkable effects in terms of preventing environmental pollution.

In addition, even when operating conditions are severe, the amount of human waste in the toilet tank can be re-foamed in the re-foaming tank to increase the processing capacity of the human waste, making the gas discharged outside the system odorless. In addition, one end of the drain vibrator that returns the sewage in the re-foaming tank to the toilet tank is sealed with water, so the air lift force from the air supply device and the suction by the exhaust fan can be achieved. It can promote negative pressure and further accelerate the evaporation and drying of night soil.

In addition, by using a two-unit human waste treatment device, one of them can function as an auxiliary device, and the ability to process human waste fluid can be greatly improved.
