Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste treatment apparatus and a waste treatment method capable of simply incinerating waste such as human waste.

[0002]

2. Description of the Related Art Conventionally, there have been various methods for treating human waste. The first method is a method in which human waste is stored in a toilet tank provided in each household, pumped by a vacuum car on a regular basis, and collectively treated in an human waste treatment plant. The second method is a method of transporting human waste together with water from each household or the like to a human waste treatment plant by using a sewer pipe to collectively process the human waste. The third method is to store human waste once in a septic tank and purify it with microorganisms such as bacteria. Of the three methods described above, the first method accumulates human waste in each household, which causes a bad odor. Further, the second method requires enormous cost for constructing the treatment plant and facilities up to the treatment plant. further,
In the third method, there were problems such as the movement of bacteria and the reduction of treatment amount in cold regions. Therefore, the present inventor has invented a flush toilet that incinerates human waste on the spot by an incinerator adjacent to each toilet (Japanese Patent Laid-Open No. 2-289).
729). In this flush toilet, the toilet bowl and the incinerator are connected by a vertical dropping pipe for human waste, and a dropping pipe for human waste is opened in the middle of the dropping pipe for dropping human waste.
A shutter that closes when urination or defecation is completed is provided to drop the human waste into an incinerator and incinerate it.The washing water used to wash the toilet bowl is flowed in a different direction to be filtered and reused for cleaning the toilet bowl, etc. It is a thing. The above-mentioned incinerator used a hemispherical kettle to incinerate human waste, and after incineration, sucked out the ash.

[0003]

However, since the human waste incinerated in the incinerator contains a considerable amount of salt, salt components and the like adhere to the inner wall surface of the incinerator after incineration. This salt component or the like sticks hard to the inner wall surface of the pot and gradually accumulates, and in extreme cases, the rotary blades may become unrotatable. Therefore, an object of the present invention is to provide a waste treatment device and a treatment method in which salt components and the like do not stick to the inner surface of the incinerator.

[0004]

In order to solve the above problems, the present invention has the following constitution. That is, as the sewage treatment apparatus, while heating the incinerator in which the sewage and the like are heated, the sewage treatment apparatus in which the sewage and the like is agitated by the rotary blades provided in the incinerator is incinerated while being incinerated. It is characterized in that a rotary blade for stirring human waste and the like is rotatably provided, and an elliptical sphere that rolls due to the rotation of the rotary blade is placed in the incinerator. In addition, as a sewage treatment method, the human waste that has been put into the incinerator is incinerated by heating the incinerator while stirring with rotating blades, and when the human waste is incinerated, water is supplied into the incinerator and the incinerator is incinerated. The elliptical sphere placed inside was rolled by the rotation of the rotary blades to dissolve the salt, etc. adhering to the inner surface of the incinerator in water, and the water in which this salt, etc. was dissolved was discharged by the suction means. It is characterized by

[0005]

[Operation] The operation will be described. The incinerator in which the human waste is put is heated and the human waste is incinerated while being stirred by the rotary blades. Then, when human waste is incinerated, water is supplied into the incinerator, and the elliptical sphere placed in the incinerator is rotated by the rotation of the rotary blades to remove the salt and the like adhering to the inner surface of the incinerator. It is made to dissolve in water, and the water in which this salt content is dissolved is discharged by the suction means.

Next, the operation of the flush toilet of the above embodiment will be described along with a more detailed structure. (1) When the toilet seat 11a or lid 11b of the toilet bowl 10 is opened, the first shutter 18a is opened. The second shutter 18b closes the falling barrel 16. (2) Defecate or urinate. (3) By operating the button or the like, the first shutter 18a is operated to close the drop cylinder 16, and the second shutter 18b is opened in conjunction with this operation. Then, human waste and the like fall into the incinerator 14. The first shutter 18
It is possible to flush the flush water for the toilet bowl and the flush water for the hips, etc., only when the drop cylinder 16 is closed by a, and no extra water flows when the first shutter 18a is open. . (4) The second shutter 18b that has been opened for a predetermined time is automatically closed. (5) On the other hand, after the dropping cylinder 16 is closed by the first shutter 18a, water for flushing the toilet is flushed. This water falls 16
Is dropped, the flow direction is changed by the first shutter 18b, the flow is made through the branch pipe 32, and is sent to the filtering device 34. If necessary, the flush water for the hips and the like is sent to the filter device 34 together with the flush water for the toilet bowl. In addition, since the branch pipe 32 and the first shutter 18a are not at the same height, a small amount of water is accumulated in the portion of the interval L. When the water is used next time, the first shutter 18a opens and drops on the second shutter 18b to collect and prevent human waste from adhering to the second shutter 18b. (6) When the water in the low tank 11 flows, the filtering device 34
Low tank 1 through the water return pipe 58 in the tank
Return within 1. When the amount of water in the raw tank 11 is less than the predetermined amount, tap water or the like is separately supplied. (7) On the other hand, the human waste sent to the incinerator 14 is incinerated.
In this case, the electric heater 15 is energized to heat the incinerator 14. The heat of the electric heater 15 is supplied to the pot body 14a without waste by the action of the reflection plate 14b. At this time, the rotary blades 28 are rotated to stir the excrement and efficiently incinerate. It should be noted that the inflow of outside air into the incinerator 14 is caused by the oven body 1
It is performed from a gap 14d between the opening edge of 4a and the lid 15.
Further, the malodorous vapor evaporated in the incinerator 14 is deodorized by the deodorizing portion of the chimney 23 and discharged to the outside. (8) After the incineration of human waste is completed, water is supplied from the water supply pipe 42 into the incinerator 14. This is because the ellipsoidal sphere 40 scrapes away the salt and the like adhering to the inner peripheral surface and the bottom surface of the incinerator 14 by supplying water with the salt and the like that are about to solidify and heating while rotating the rotary blade 28. Dissolve salt and so on and stir. When water remains inside the incinerator 14, the electric heater 13 is de-energized (it may be automatically performed by a known electric means). When the temperature of water drops, the incinerator 1 is rotated while rotating the rotary blade 28.
The residue containing salt and the like in 4 is sucked by the dust collector 30. Since the rotary vanes 28 are formed in a plane S shape, the elliptical sphere 40 tends to roll to the center, so that the residue in the incinerator 14 is also collected in the center, and it is easier to suck the dust with the dust collector 30. Becomes The sucked residue is filtered and the water is discharged.

A modified example will be described. FIG. 4 shows a schematic view of an incinerator for garbage and the like. The incinerator 60 has almost the same structure as the incinerator. It should be noted that only the first shutter 18a is provided on the drop cylinder 16 and the second shutter 18b is not provided. In addition, the first of the falling barrel 16
Immediately before the shutter 18a, a branch pipe 32 for separately flowing water from the drop cylinder 16 by the first shutter 18b.
Connected with. In addition, a funnel-shaped insertion opening 62 for inserting garbage and the like is formed at the tip of the falling tube 16. In addition to the other structures, for example, the structure of the incinerator 14 and the structure in which the elliptical sphere 40 is put in the incinerator 14,
The water supply pipe 42, the dust collector 30, the chimney 23 and the like have the same structure. The incinerator 60 incinerates garbage and the like, and the incinerator 14
The same operational effects as those of the above-described embodiment are achieved, such as preventing salt from adhering to the inside. Although various explanations have been given with reference to the preferred embodiments of the present invention, the configuration of the filtering device of the present invention,
The shape and configuration of the incinerator, shutter opening and closing mechanism, etc.
It goes without saying that many modifications can be made without departing from the spirit of the invention.
