Description

[Detailed Description of the Invention] << Industrial field of application >> The present invention relates to a waste treatment device, more specifically, a waste treatment device capable of washing waste with a small amount of water, particularly in limited places such as vehicles and buses. The present invention relates to a limited-type waste treatment device that is provided in the above and uses a limited small amount of cleaning water.

《Prior Art》 In a waste treatment device including a general toilet, the device that flushes the waste in the toilet uses the water pressure in the water purification container and the potential energy of the water purification container, Was flowing.

In addition, a waste treatment device installed in a moving device such as a vehicle or a bus cannot obtain a water source for washing the waste freely like an ordinary water pipe, so that a limited amount of water is stored in a storage tank. It is stored and the water is circulated for use.

Such a circulation type sewage treatment apparatus generally puts purified water for cleaning in one tank at about half the maximum capacity of the tank, mixes deodorant chemicals with this purified water, and circulates it while filtering it. I was using it. That is, the used sewage was circulated and used many times without being discarded, and the sewage concentration increased as the number of times of use increased.

Further, the capacity of the storage tank of these waste treatment devices is determined as follows.

Calculate the total amount of waste that is expected by multiplying the number of times the toilet is used per operation of the vehicle with 0.27 liters of waste per run. The same amount of wash water as this total amount of waste is added, and as a margin, 20% is added to this combined amount to make the storage tank capacity.

For example, taking a recycling type waste treatment device used in Shinkansen vehicles as an example, the storage tank capacity is 1080 liters, and wash water 4
50 liters, expected total waste volume 450 liters, surplus amount 180 liters. The amount of wash water used per toilet is 15 liters. 1 in this case
The calculated maximum number of uses in the number of operations is 1666.

<Problems to be solved by this device> In recent years, there is a problem that a waste treatment device including a large number of general toilet bowls may use too much water for one time, in the case of protection of water resources or water shortage. It has been pointed out.

Further, in a circulation type waste treatment device provided in a vehicle, a bus, etc., the cleaning water flowing the waste is clean water that does not mix with the waste at the beginning of use, but as the number of times of use increases,
It was impossible to prevent the bad odor generated even if the deodorant was added, because the proportion of waste increased. In particular, in the hot summer months, there is a problem that the bad odor becomes strong and discomfort increases.

Further, since the used water contains not only dirt but also paper and cloth, it is necessary to install a filtering device, which causes a problem such as clogging of the device.

Also, after one operation, the storage tank is cleaned, the used water mixed with filth is discarded, and new purified water is added, but if cleaning is insufficient, filth will be mixed with the cleaning water from the beginning of the next use, and a bad odor will be generated. There was a problem that occurred, and it was a problem that a large amount of water was used at the time of cleaning and the labor of cleaning work could not be neglected.

Further, even if an attempt is made to reduce the degree of pollution or to increase the amount of cleaning water, there is a problem that it cannot be done because the place where the device such as the storage tank is installed is limited.

An object of the present invention is to obtain a filth treatment device that can wash filth with a small amount of water.

Furthermore, it can be installed in a limited narrow space, and it does not produce a bad odor.
It is an object of the present invention to obtain a waste treatment device with few failures and less cleaning work.

<Means for Solving the Problem> This invention is directed to a storage tank, a partition wall made of a variable shape and dividing the storage tank into a clean water container and a waste water container, and a discharge pipe connected to the waste water container and a pressure pump. Provided is a sewage treatment apparatus comprising a toilet bowl supplied with purified water from a water purification container through a water passage, and a high-pressure spray nozzle installed at the end of the water passage to spray the cleaning liquid into the toilet bowl in a fan shape. To do.

《Action》 The water purification container and the waste water container partition use variable shapes, so when the water purification container is in the maximum capacity state, the waste water container is in the minimum capacity state, and the waste water container flows in as the number of times of use increases. The pressure of dirty water causes it to swell naturally, while the water purification container naturally shrinks.

<< Embodiment >> The waste treatment apparatus of the present invention is exemplified by a limited-type waste treatment apparatus installed in a vehicle or the like, and FIG. 1 and FIG. Fig. 7 showing a schematic explanation of the embodiment, and Fig. 3 to Fig. 6 showing one embodiment of the toilet used in this waste disposal device, showing the plane of the Japanese style toilet, Fig. 3 and its side surface. This will be described with reference to FIG. 4, FIG. 5 showing the plane of the Western-style toilet, and FIG. 6 showing its side surface.

(1) is a toilet bowl, and (2) is a storage tank. A water purification container (3) and a waste water container (4) are provided in the storage tank (2). The water purification container (3) communicates with a high pressure spray nozzle (7) provided in the toilet (1) by a water passage (5). The waste water container (4) communicates with the discharge pipe (8) of the toilet bowl (1). (6) is a pressure pump, which is provided in the water passage (5). Reference numeral (11) is an insertion port for inserting cleaning water, which is provided in the upper part of the storage tank (2) and opens into the cleaning container (3).
(12) is an outlet for discharging sewage, which is provided in the lower part of the storage tank (2) and opens into the sewage container (4).

The nozzle (7) for high-pressure spray provided in the toilet (1) has a fan-shaped opening (9), and the number, direction, and position of the nozzle (7) differ depending on whether it is a Western style, a Japanese style, or its internal shape.
3 and 4 show a Japanese style toilet (1) a, and FIG.
FIG. 6 shows a Western style toilet (1) b.

In this embodiment, the Japanese style toilet (1) a is provided with four high pressure spray nozzles (7), two on the left and right on the left and right sides of the toilet. The four high-pressure spray nozzles (7) are installed so that the jet outlets (9) are in the left and right directions, but depending on the size and shape of the toilet bowl (1), the number of high-pressure spray nozzles (7) and , The direction is changed, and the cleaning water is sprayed in a fan shape at a high pressure so that the dirt can be efficiently cleaned.

Further, in the Western-style toilet (1) b, the nozzle (7) for high-pressure spray is placed at an appropriate position above the inside of the toilet to eject the nozzle (9).
Are provided so as not to face each other, but the number, the direction, and the mounting position are not limited to this, but depend on the size and shape of the toilet bowl (1). The number of high-pressure atomizing nozzles (7) is 3 in this embodiment.
The number is about 3, but about 3 to 7 may be sufficient.

The pressure pump (6) provided in the water passage (5) is a motor,
It has a limit switch (not shown) and is connected to a pedal (not shown) attached to the toilet bowl (1). After using the toilet bowl (1), the pedal is pressed for a certain period of time to operate for a certain period of time, and the wash water in the water purification container (4) is passed through the water passage (5).
It is ejected from the high-pressure atomizing nozzle (7). In this example, the operating time of the pressure pump (6) is 10 to 15 seconds, 5 to 7 kg /
The washing water in the water purification container (3) is ejected from the high-pressure spray nozzle (7) by the pressure of cm ² . At this time, the amount used once is about 0.25 l or less, and the jetted water is atomized into a mist or a fan.

In this embodiment, the storage tank (2) forms a partition wall (10) by fixing a sheet-like material inside, and one of the water tank (3) communicating with the water passage (5) by this partition wall (10) The other, which communicates with the outlet (8) of the toilet (1), is configured as a waste water container (4). The sheet-like material forming the partition wall (10) may be a waterproof and flexible material such as rubber or soft synthetic resin, and its size is sufficiently larger than the cross-sectional area of the storage tank (2). Area. Also, the partition (1
The mounting position of (0) is provided at a position where the water purification container (2) is slightly narrower than the center where the storage tank (2) is half and half.
This is because the volume of the waste water container (3) is the amount of the waste water added to the waste water.

When the dirty water container (4) is empty and purified water is put into the clean water container (3), the amount of wash water spreads to the dirty water container (4) side in the storage tank (2) (FIG. 1). Then, as the number of times of use increases, the amount of sewage on the sewage container (4) side increases, and conversely, the amount of purified water in the water purification container (3) decreases. Therefore, since the partition wall (10) can be deformed, the partition wall (10) easily spreads to the water purification container (3) side by the pressure of the dirty water mixed with the filth.
The capacity of the waste water container (4) can be used up to the full capacity of the storage tank (2) (Fig. 2).

In this embodiment, the capacity of the storage tank (2) is 1080
l, the amount of purified water to be put in the water purification container (3) is 500l, the estimated total amount of waste is 580l, and the maximum amount of wastewater combined is 1080l.
The sewage container (4) has a partition wall (10) and a clean water container (3).
By expanding to the side, the capacity in the storage tank (2) can be maximized. In this case, the maximum number of uses per operation is 1850.
The number of times is significantly higher than the maximum number of usage of 1666 in the conventional example of 1666 times.

As another embodiment of the storage tank (2), the water purification container (3) may be formed into a bag shape with a flexible and waterproof sheet-like material as shown in FIG. In this case, the remaining portion of the storage tank (2) other than the bag-shaped water purification container (3) becomes the sewage container (4). On the contrary, the waste water container (4) may be formed in the same bag shape, or both may be formed in the same shape and material.

<< Effect of Invention >> Therefore, according to this invention, it is possible to treat filth with a smaller amount of water than in the past.

Further, in a waste treatment device such as a vehicle in which the amount of water and the position of the storage tank are limited, it is possible to use more times without changing the size of the storage tank.

Further, even if no chemicals are used, the generation of a bad odor is almost eliminated, and it becomes more hygienic.

Further, in the case of a circulation type waste treatment device, it is necessary to attach a filtering device in order to filter paper, dirt and the like, but this is not necessary, and the device can be simplified and the cost can be reduced.

Further, since the wash water does not mix with the dirty water, work efficiency is improved in the storage tank cleaning, such as saving water and shortening work time.
