Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a compost-producing human waste treatment device that ferments frozen ground, which is excrement from toilets, to deodorize and sanitize it, as well as to compost it. This invention relates to a human waste agitation and transfer device that agitates and mixes human waste from a toilet bowl and transfers fermentation additives from an additive container to a hanging toilet tank.

[Prior Art] The frozen ground transfer means used in conventional devices of this type is one in which a rotating shaft with a spiral conveyor fixed to the transfer tube is built into the transfer tube, or a similar transfer device. Some have a screw conveyor built into the pipe body.

[Problems to be solved by the invention] The frozen ground transfer device not only simply transfers the human waste and additives taken in at the introduction part of the toilet bowl or additive container to the curing tank, but also transfers them to the curing tank. In order to more efficiently and reliably ferment the frozen ground during transport, it is necessary to transport the frozen ground and additives while sufficiently stirring and mixing them. Also, the paper that is thrown into the toilet bowl along with human waste must be crushed as finely as possible.

On the other hand, in order to improve the efficiency of fermentation in the curing tank, it is preferable that the mixture of human waste and additives is sufficiently dehydrated and heated to an appropriate temperature condition.

The conventional transfer device described above does not meet such requirements.

Configuration for Solving Problem E] The gist of the configuration of the present invention is an introduction part for human waste and fermentation additives, a mixing transfer part for mixing and transferring them, and a mixing transfer part for introducing human waste and fermentation additives from the mixing transfer part. In a compost-producing bed urine treatment device comprising a curing tank configured to receive and cure a mixture of fermentation additives to produce compost, a connection opening connects the mixing transfer section to the introduction section; A transfer pipe having a connection opening connected to the curing tank and the curing feces tank, a hollow rotating shaft inside the heating body arranged along the axial direction within the transfer pipe, and a vicinity of the corresponding position of the connection opening connected to the introduction part. Compost generation comprising the above-mentioned human waste and additive removal and transfer means fixed to the above-mentioned hollow rotating shaft in the above, and a plurality of stirring transfer blades fixed to the above-mentioned hollow rotating shaft at other positions in a spaced manner. This is a frozen ground agitation transfer device in a mold bed urine treatment device.

For the transfer pipe listed in L, materials such as plastic or metal can be used, but in order to make the heating by the heating element as efficient as possible, it is preferable to use a material that has good heat retention properties, such as plastic. When using it, you must also pay attention to its heat resistance.

The heating body installed in the hollow rotating shaft is not limited to a specific one, and any suitable heating means can be freely selected. For example, hot water or the like may be passed through the hollow rotating shaft. However, electric heaters are easy to configure and use, and if the necessary temperature can be obtained, the heating element can be installed in a part of the rotating shaft rather than all of it. The heating is controlled by appropriate control means so that the object to be heated, such as human waste, can be maintained at the required temperature. For example, use a thermostat. At this time, the temperature of the object to be transferred, such as urine, to be kept warm is preferably about 60 to 80°C. When using an electric heater as a heating element, it is necessary to supply power to the rotating shaft, but this can be easily done using a slip ring, etc. Since the zero rotation speed is low, problems such as contact wear occur. There are few.

The purpose of the removal and transfer means is to transfer the human waste visible from the toilet bowl to a position where it cannot be seen as quickly as possible. Therefore, it is best to use a conveyor device that is as efficient as possible and has a high transfer speed.It is also better to use a conveyor that does not allow human waste to adhere to the conveyor itself.Specifically, candidates include spiral conveyors and screw conveyors. Yes, but from the latter point of view, a spiral conveyor is better.

The stirring transfer blade is composed of a plate-like member, and as described above,
A plurality of them are separately fixed on the outer periphery of the hollow rotating shaft. For example, a plurality of pairs of stirring and transporting blades are fixedly attached to a hollow rotating shaft at appropriate intervals. A pair of agitation and transfer blades are fixedly installed at positions 180 degrees apart from each other in the circumferential direction of the rotating shaft. Alternatively, one agitation and transfer blade is fixed to the hollow rotating shaft at appropriate intervals.

Each stirring and transferring blade is fixed at an appropriate angle with respect to the axial direction of the hollow rotary shaft so as to stir the human waste and fermentation additive and also slightly transfer the same. The above angle can be considered with a standard value of about 45°. The agitation transfer blade immediately before the connection opening to the curing feces tank is fixed at a small angle with respect to the axial direction of the hollow rotary shaft so as to have a strong agitation effect. In addition, a transfer member facing in the opposite direction is fixed at a position beyond the connection opening of the hollow rotating shaft so as to have a transfer force in the opposite direction to that of the other stirring and transfer blades.

By the way, the spacing between the stirring and transfer blades in the axial direction of the rotating shaft should be considered in conjunction with other conditions, such as the installation angle in the axial direction with respect to the hollow rotating shaft, and should be compared so that the transfer force is sufficiently small while providing sufficient stirring force. It is best to set the target to be wide open.

Further, a rotational driving body is connected to the hollow rotating shaft, and the rotational driving force is applied for a predetermined period of time when the switch is turned on after defecation. The predetermined time is determined based mainly on the relationship with the transfer speed of the agitation transfer blade. Specifically, the above-mentioned predetermined time is determined in the range of about 1 hour to 3 hours, taking into account the sufficient stirring action by the stirring transfer blade and also the time for applying an appropriate heating action by the heating element. is appropriate.

As the fermentation additive, conventionally used peat moss, sawdust, or other waste wood powder may be appropriately used.

[Function] Since the present invention is configured as described above, the present invention works as follows in the composting type bed urine treatment device.

Since the present invention constitutes a part of the above device,
This will be explained along with its overall function.

After defecating, when you turn on the start switch according to the normal usage, the one-rotation driver starts operating, rotating the hollow rotating shaft, and at the same time, the additive feeding device also starts driving, and transfers for a predetermined period of several tens of seconds. Fermentation additives are charged into the tube from an additive container. This means that the additive is dropped onto the frozen ground of feces and other substances that have already entered the transfer pipe through the connection opening, or onto the location where they have been transferred. In addition, at this time, since the hollow rotating shaft has already started rotating as described above, human waste such as feces and additives are immediately removed from the vicinity of the opening by the removal moving means placed near the connection opening, and the agitated transfer is carried out. It will be transported to a location where the blades will be installed. Therefore, the frozen ground and the like immediately move to a position where they cannot be seen from above the toilet bowl, so that it does not cause any discomfort to subsequent users.

Next, the human waste and additives are slowly transferred while being sufficiently stirred by the action of the stirring transfer blade.

The agitation transfer blade has a strong stirring action due to its structure, and the transfer action is set to be sufficiently weak, so that it is sufficiently stirred during the transfer process, and a substantially complete mixture of frozen ground and additives can be obtained. Moreover, since a heating element is disposed inside the hollow rotating shaft, the mixture is heated to the predetermined temperature.
Water is removed and fermentation is promoted.

In this way, the mixture is transferred to the curing tank in a state where a considerable amount of moisture has been removed and fermentation has started. Therefore, it gives good results to the subsequent fermentation in the curing tank and to the production of compost.

[Example] An embodiment of the present invention will be described below based on the drawings.

As shown in FIG. 1, the inlet opening 4 of the transfer pipe 3 is connected to the toilet bowl l via the connecting pipe 2. A feed pipe 6 of an additive container 5 is connected to the middle of the connecting pipe 2. This feed pipe 6 has a conveyor coil 7 built in it for feeding additives, and when the start switch is turned on, the conveyor coil 7 runs for a predetermined period of several tens of seconds.
For example, a timer is set to rotate for about 30 seconds to feed the additive.At the same time, the rotation drive unit 9 for rotating the hollow rotating shaft 8, which will be described later, also starts rotating, but this generally takes about 30 seconds. Set the driving time between 1 hour and 3 hours,
A timer shall be set. Note that sawdust was used as the additive.

The discharge opening lO of the transfer pipe 3 is connected to a curing feces tank 12 via a connecting pipe 11. This curing tank 12 is equipped with a heating section 13 at the bottom, which heats the mixture of frozen ground and fermentation additives introduced therein to an appropriate temperature to promote fermentation.

The hollow rotating shaft 8 is rotatably disposed in the transfer pipe 3 along its axial direction. A heating wire 14 is arranged inside the hollow rotating shaft 8, as shown in FIG. This heating wire 14 is fixed in the hollow rotating shaft B by filling the periphery with insulating heating conductor powder. Alternatively, other heaters may be installed in the hollow rotating shaft 8. The heating wire 14 (or other heaters, if adopted) is powered by electricity to maintain the surrounding area at an appropriate temperature. A thermostat is attached to control the supply, and the temperature to be maintained is 60℃.
It is appropriate to set the temperature to about 80°C. Note that a slip ring 15 as shown in FIG. 3 can be used to supply power to the heating wire 14 described above so that there is no problem when the hollow rotating shaft 8 is rotated. 16a and 16b are contacts, and the heating wire 14 is always powered on when the main switch is turned on.

Of course, it is controlled by a thermostat to keep it at an appropriate temperature.

As shown in FIG. 1, the hollow rotating shaft 8 is further provided with a spiral conveyor 17, which is a means for removing and transporting human waste and additives, at a position corresponding to the inlet 0Bs4, and a plurality of pairs of conveyors are installed at other positions. Stirring transfer blades 18, 18... are fixedly installed.

The agitation transfer blades 1B, 18, . . . are composed of plate-like members, and as described above, a plurality of the blades are fixed to the outer periphery of the hollow rotating shaft 8 in a spaced manner. In this example, as shown in Figure 1,
A plurality of pairs of stirring transfer blades 18, 18... are connected to a hollow rotating shaft 8.
They are fixedly installed in pairs at appropriate intervals. A pair of agitation transfer blades 18.18 are arranged in the circumferential direction 1 of the hollow rotating shaft 8.
Fixed at 80° position. Each stirring transfer blade 18.18・
... are fixed at an appropriate angle with respect to the axial direction of the hollow rotary shaft 8 so as to stir the frozen ground and the fermentation additive and also exert a slight transfer action on the frozen ground and the fermentation additive. The above angle is 4
5'' can be considered as a standard. However, the agitation transfer blade 18.1B just before the discharge opening 10 connected to the curing feces tank 12 is attached to the axis of the hollow rotating shaft 8 so as to have a strong agitation effect. Fixed at a small angle to the direction.

Further, at a position beyond the discharge opening 10 of the hollow rotating shaft 8, an agitation transfer blade 18.1B is fixed in the opposite direction so as to have a transfer force in the opposite direction to the other agitation transfer blades 18.18... . This is to prevent the mixture of human waste and additives from being transferred in the transfer tube 3 beyond the discharge opening 10, pressed against the tube end, and solidified.

By the way, the spacing of each stirring transfer blade 18 in the axial direction of the hollow rotating shaft 8 is considered in conjunction with other conditions, such as the installation angle with respect to the axial direction of the hollow rotating shaft 8 described above, to ensure that sufficient stirring force is provided while the transfer force is low. Set it relatively wide so that it is sufficiently small.

In this embodiment, since it is constructed in this way, it functions in a first order manner in the composting type frozen ground processing apparatus.

The operation of the entire human waste treatment apparatus described above will be explained.

First, after defecating, when the start switch is turned on, the conveyor coil 7 of the additive feed pipe 6 and the hollow rotating shaft 8 start rotating. There, the transfer pipe 3 has already been opened from the inlet opening 4.
The frozen ground containing feces, etc. inside is sent to the spiral conveyor 17.
Transfer is started, and at the same time, sawdust is thrown onto the frozen ground or onto the spiral conveyor 17 after the movement through the feed pipe 6 and the connecting pipe 2. Sawdust is an additive for fermentation as described above, and is fed in an appropriate amount by the conveyor coil 7. This sawdust is also immediately transferred, and the human waste and sawdust are mixed slightly and quickly leave the vicinity of the inlet opening 4 and move to the installation position of the stirring transfer blades 18, 18, . . . . Therefore, from above the toilet bowl 1, the frozen ground etc.
Since it is immediately moved to a position where it cannot be seen, it does not cause any discomfort to subsequent users.

After that, the hollow rotating shaft 8 continues to rotate for a predetermined period of time (predetermined 1 to 3
time) Continue the rotating operation, stirring transfer blade 18.18
... Stir and mix the human waste, sawdust, etc. Since the agitation transfer blade 18 has the above-mentioned configuration, the transfer action is very weak, and the human waste, sawdust, etc. are transferred slowly, and at the same time, the stirring action is very strong, so that the above-mentioned human waste and sawdust are sufficiently stirred and mixed. is a nearly perfect mixture. Furthermore, the paper mixed in the frozen ground is also torn to shreds and becomes finely mixed in the above mixture. Moreover, as shown in FIG. 2, a heating wire 14 is provided inside the hollow rotating shaft 8, so that the mixture is heated appropriately and fermentation starts under suitable fermentation temperature conditions. . Heating also promotes the evaporation of moisture and provides a dehydrating effect. Since the stirring transfer blade 18.1B just before the discharge opening 10 is installed at a fixed angle as described above, the mixture is more strongly stirred before being transferred to the li raw stool tank 12. In addition, the agitation transfer blade 18.18 installed at a position beyond the discharge opening 1O has a transfer action in the opposite direction to that of the agitation transfer blade 18, 18, located at other positions. There is no movement of the mixture beyond the discharge opening 10.

Fermentation of the above-mentioned mixture is thus started, and the oxen from which a considerable amount of water has been removed are transferred to the curing tank 12. Therefore, since the mixture is transferred to the curing tank 12 after fermentation has already started, the subsequent fermentation in the curing tank 12,
It can give good results in compost production.

[Effects of the Invention] According to the present invention, during the process of transferring frozen ground to a curing tank, it is possible to sufficiently stir and mix the additive, and to start fermentation of the mixture and remove a considerable amount of moisture. It has the effect of being able to remove some degree of damage.
