Abstract

PURPOSE:To prevent a stink of excretion from reeking and process it at a makeshift toilet in a sanitary condition by heating a container containing excretion, from outside, and drying it, at the same time, furnishing thermal accumulator in the container, and stirring them with stirring means. CONSTITUTION:When excretion is stored in a drying oven 13, electricity is applied to a heater 18 for heating up whole drying oven 13, and at the same time, the heat is also accumulated in thermal accumulators 38 contained in the drying oven 13, and the excretion in the drying oven 13 is thus heated with both the heat from the drying oven 13 and the heat from thermal accumulators 38. As a driving pipe 32 is rotated by a motor 50, each of stirring blades 37 laterally rotates in the bottom of the drying oven 13 and stir excretion and thermal accumulators 38 at the same time. At this moment, a heat exchanger pipe 19 is heated up with the heater 18 and an air in it is heated up and transferred toward a direction to a connecting pipe 65. At the same time, a motor 72 in exhaust box 71 is activated, and an air containing a stink which is being taken in by a suction pipe 66 is sent to a reheat pipe 20, then the air is heated up and is sent to dust-absorption/catalyst box 67 for removing a stink by contacting with a catalyst body 69 and exhausted from a exhauster 71.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is for processing raw urine outdoors where there is no purification facility, in traffic tunnels such as ships and trains, and in tunnels where vacuum cars cannot enter. The present invention relates to a human waste drying device that is capable of drying human waste.

[Conventional technology]

In ordinary houses, raw urine excreted from the human body is either discharged into the sewer system using a flush toilet, or temporarily stored in a purification layer and purified before being released into a general river. For example, at sports festivals, trade fairs, gatherings, and other venues where large numbers of people would be involved, temporary toilets were set up to dispose of urinary rhinoceros.

Traditionally, movable temporary toilets have not been used to dispose of human waste outdoors or in places without purification facilities, but many of these have a toilet tank that stores NH, and the human waste excreted from the human body is collected in this toilet. It was stored in a tank.

Therefore, after use, the temporary toilet must be used to suck up the accumulated human waste using a vacuum car or the like, collect it, and then dispose of it, which is time-consuming.

In addition, transportation systems such as trains, buses, and ships that travel long distances are equipped with special tanks to store excreted excreta.The human waste is stored in these tanks and treated with odor-proofing chemicals. After that, the method of collecting the waste using a vacuum car at the terminal station or relay point was to use a boat.

As described above, most of the conventional methods of disposing human waste in temporary or mobile transportation systems involve storing excreted human waste and then collecting and disposing of it, which is extremely unhygienic. I had to say yes. For this reason, when used for a long time, excreted human waste remains,
Not only did it cause a bad odor, it was also disliked by workers, so it was not desirable from the perspective of modernizing processing.

For this purpose, various hygienic treatment methods have been considered. For example, there is a method in which chemicals are added together with human waste to sterilize and prevent deodorization. This is transportation I such as Shinkansen! Although it is often used in leaps and bounds, it cannot be used for a long period of time because the chemicals circulate within the tank, and it also has the disadvantage of increasing costs due to the use of chemicals. In addition, a method of storing human waste in bags made of plastic or the like and banking the bags to prevent the release of odors has been considered. However, it is necessary to use a plastic bag with a fairly large area for each excretion, which increases disposal costs and
The subsequent processing to separate the human waste from the plastic bags was a hassle.

Another method is being considered in which the excreted human waste is directly dried using the heat of a burner or the like. However, since most of the components of human waste are water, removing this water requires a lot of energy and requires a long processing time.

For this reason, the same inventor as the applicant of the present application has proposed a processing device in which rotating blades are provided in a tank for storing [[], and a heat storage body is stored in the tank. With this configuration, by heating the tank from the outside and rotating the blades at the same time, it is possible to quickly dry the [[[[] and evaporate most of the water in the human waste (for example, Japanese Patent Application No. 124150 of 1983). In this method, the energy required to heat the tank is very large, and the heated heat is directly released to the outside, resulting in a high energy loss.

[Problem to be solved by the invention]

In view of the above-mentioned drawbacks, the present invention aims to store excrement and urine excreted from the human body in a tank, heat the tank from the outside, and at the same time stir it with rotating blades to quickly dry it. When heating this tank, a pipe for supplying air is wrapped around the outer circumference of the tank, the air to be supplied into the tank is heated in advance, and the heated air is supplied into the tank. It is an object of the present invention to provide a bed bundle drying device that can extremely reduce energy loss.

[Means for solving problems]

The present invention includes a heat-resistant container for storing human waste, a heating means for heating the container from the outside, a stirring means having a plurality of blades for stirring the human waste stored in the container, and a plurality of stirring means for stirring the human waste stored in the container. a spherical heat storage body, a heat exchange pipe that is wrapped around the outer circumference of the container and supplies air sent from the outside into the container; The present invention provides a bed bundle drying device characterized in that it is comprised of a reheating pipe for heating the bed bundle.

[Effect]

In the present invention, [lH is stored in a heat-resistant container,
The human waste is dried by heating this container from the outside.

A heat-resistant heat storage body such as ceramic is housed inside the container, and since this heat storage body and human waste are stirred by the stirring means, heat from outside the container is absorbed by the container itself and its M
The entire heating body is heated, and the heat radiated from the surface of the M heating body heats the human waste and can quickly evaporate water. Also,
At the same time, air from the outside flows through the heat exchange pipe wrapped around the outer circumference of the container, and the heat that passes through the heat exchange pipe is heated to a considerably high temperature and released into the container. Therefore, the heat that would normally be wasted is directly supplied into the container as heated air, so that the human waste can be dried more quickly.

In this way, the human waste is not only heated from the outside by a heat source, but also the heat generated from the surface of the heat storage body and the air heated by the heat exchange pipe are blown directly into the KH, so the human waste is heated from the inside and outside of the container. It will be left to dry.

Finally, the urine and urine in the container becomes powdered and can be dried to a state where no odor is generated, and when used in a temporary toilet, it can be used for a long period of time.

2 and a fan 73 are housed.

Next, the operation of this embodiment will be explained.

First, a person who wants to relieve himself enters the temporary toilet 1 and defecates toward the toilet bowl 6. The excreted excrement falls from the toilet bowl 6 through the introduction pipe 39 and is temporarily accumulated inside the drying pot 13. Drying pot 13 for human urine beyond a certain amount
When stored inside, the heater 18 is energized to generate heat,
The entire drying pot 13 is heated by the heat from the heater 18, and the motor 50 is operated to rotate the drive pipe 32 via the worm 46 and the worm gear 45.

Then, the heat generated from the heater 18 heats the entire drying pot 13, and the heat is also stored in the heat storage body 38 housed inside the drying pot 13, and the human waste stored in the drying pot 13 is heated by this heater 18. The entire drying pot 13 is heated and the heat from the heat storage body 38 causes the moisture to be evaporated.

Since the drive pipe 32 is rotated by the motor 50, each stirring blade 37 rotates horizontally at the bottom of the drying pot 13, stirring the urine and heat storage body 38 at the same time, and the accumulated human waste is The mixture is stirred so that the temperature is uniform throughout. At this time, since the urinal comes into contact with the surface of the heat storage body 38, the heat of the M heating element 3B is transmitted from the surface to the human waste, thereby making it possible to hasten the temperature rise of the entire urinal.

Further, at this time, the motor 62 is operated and the fan 63 is rotated, so that air from the outer circumference of the ventilation pipe 4 flows into the heat exchange pipe 19. Since this heat exchange pipe 19 is in contact with the heater 18, the heat exchange pipe 19 is heated by the heater 18, and the air flowing inside the pipe is heated and transferred in the direction of the connecting pipe 5. The hot air supplied from the connecting pipe 5 is then sent to the vent 44.
0 which will flow within the drive pipe 32 through 42
Next, the hot air is released from the bottom of the drying pot 13 through the ventilation hole 35 and the communication hole 36, and the heat storage body 38
Hot air is blown onto the human waste heated by the drying pot 13, and ffl[ is heated from the inside and outside of the drying pot 13, thereby promoting drying.

At the same time, the motor 72 in the ventilation box 71 is activated,
As the fan 73 rotates, the air inside the drying pot 13 is sucked in the direction of the suction pipe 66, and the air sucked by the suction pipe 66 is sent to the reheating pipe 20. In this reheating heater 20, since it is heated by the heater 18, air containing bad smells such as ammonia is reheated when passing through this reheating pipe 20, and is sent into the dust collection/catalyst box 67. .

Inside this dust collection/catalyst box 67, impurities and scum are first removed by a filter 68.Next, the reheated air comes into contact with a catalyst body 69 and is promoted to oxidize, thereby oxidizing malodorous components and causing odor. is removed. The air that has passed through the dust/catalyst box 67 then passes through a discharge pipe 70 and is discharged into the air from an exhaust fan 71. Although the released air contains moisture from drying the urine, it does not contain any bad odor and is released as clean air from which dust, dirt, etc. have been removed.

When the heater 18 is energized for a predetermined period of time and the stirring blade 37 is rotated by the motor 50, the urine and urine put into the drying pot 13 are emitted seven times, and since the majority of the components are water, only a small amount of solid components remain. It is dried in a dry form. Therefore, once all the human waste has been dried, the heater 18 is de-energized and the motors 50, 62, and 72 stop rotating, thereby waiting for the next human waste to be processed.

〔Effect of the invention〕

Since the present invention is configured as described above, in the past, excreted urine, etc. had to be collected and processed using a vacuum car, etc., but the present invention is capable of evaporating water, which makes up the majority of the components of urine. be able to. This allows the treatment to be carried out in a temporary location, vehicle, ship, etc., and since only the evaporated water fumes are diffused, the treatment can be carried out in an extremely hygienic manner. In addition, since the drying pot uses air that has been heated by recovering heat, there is little energy loss due to heat loss (and since hot air is sent into the drying pot, the drying speed is extremely fast).
