Description

  The present invention relates to a method for treating excreta encapsulated in a pack body collected in a portable toilet used in a nursing facility, a nursing home, or a general household.

  The inventor of the present invention collects a pack of excrement that is packed every time excretion is accumulated in the toilet facility in a temporary toilet facility that is used in a temporary place such as a construction site or an event venue. The management system which processes it is proposed as Japanese Patent Application No. 2003-300830.

  The management system proposed earlier, which includes collecting and processing excrement enclosed in a pack that accumulates in temporary toilet facilities, is suitable for portable toilets used in hospitals, nursing homes, etc., or even in general households. But it was an idea that could be applied.

  However, in portable toilets used in hospitals, nursing homes, etc., or in general households, the treatment of excreta encapsulated in packs collected in the toilet can be used for temporary toilet facilities such as event venues used by many people. It is impossible to handle it in the same way as the excrement enclosed in a pack that accumulates in large quantities.

In other words, the proposed management system is too large, and in order to handle the excrement enclosed in a pack body collected in a small-capacity portable toilet installed in a general home or a nursing facility, the labor and cost are conversely reduced. It is because it does not make a compromise. In addition, the pack body for enclosing the excrement in said portable toilet and temporary toilet facilities is well-known by patent documents 1-3.

It is characterized by this.

  And the structure of the processing apparatus of the pack body which enclosed the excrement suitable for using for the above-mentioned method of the present invention consists of a rotating tank in which a water permeable portion is formed in almost the entire wall surface, and a fixed tank that covers the rotating tank from the outside. A hollow shaft that is movable up and down with respect to the inside of the rotating tub and that is provided with a radial arm at least at the tip to supply liquid to the inside of the arm and discharge the arm. A pack body in which excrement charged in a rotating rotating tub is enclosed is broken by a cutter provided on the arm of the hollow shaft, and the pack body is torn by the liquid discharged from the arm. By rinsing away the excrement flowing out from the waste, the excrement and the rinsing liquid are allowed to flow out from the water permeable portion of the rotating tank to the fixed tank, while the pack body rinsed with the liquid remains in the rotating tank. It is characterized by .

  In the present invention, the pack body enclosing the excrement to be collected is broken in the processing container, and at the same time, the waste and the pack body are separated while being rinsed by supplying a liquid such as water into the container. The excrement is sent to the sewer together with the liquid, and the pack body rinsed with the liquid and removed from the container is taken out of the container and treated as non-combustible waste. And the excrement therein can be separated, and the separated pack and excrement can be separated and sent out separately to the final treatment plant suitable for each.

  Next, embodiments of the method of the present invention will be described with reference to the drawings. FIG. 1 is a flowchart of a processing process in the method of the present invention, and FIG. 2 is a cross-sectional view showing an outline of an example of a processing apparatus used in the method of the present invention of FIG. 1 that breaks the pack body and separates the excrement and the pack body with a liquid. FIG. 3 is a perspective view of an example of a pack body of excrement.

  The pack of excrement in a portable toilet or temporary toilet facility to which the method of the present invention is applied, as shown in FIG. 3, a flexible thermoplastic long tubular film is folded into a cassette shape and installed in a toilet (not shown). The film F to be formed is set as an excrement container P (hereinafter also referred to as a pack body P) with the upper end opened in a state where the lower end is heat-sealed S1, and the excrement is transferred from the upper opening to the container P. (Excretion is finished), the upper part is heat-sealed S2 and pulled out from the tubular film F that is folded into a cassette and cut, and it falls spontaneously into the so-called toilet bowl (not shown) of the toilet And it becomes the pack body P of the aspect of FIG. 3, and accumulates at every excretion.

  The pack P sealed in a state in which excrement is accommodated in the interior, depending on the capacity of the portable toilet, as an example, when about 6 to 12 times is collected, it is appropriately collected and illustrated in FIG. Since it puts into the invention processing apparatus, the pack body P and the excrement in it are isolate | separated in the inside, and both were separated and processed, this point is described below.

  In FIG. 2, reference numeral 1 denotes a rotating tank in which a substantially entire wall surface is formed in a water permeable portion 2 with a mesh structure or a small hole of a punch medal, and a shaft 3 that is suspended from the center of the bottom 1 a is supported by a bearing 4. Thus, it is connected to a rotational drive source 5 mainly composed of a motor.

  Reference numeral 6 denotes a fixed tank disposed outside the rotating tank 1 so as to cover the tank 1 from the outside while maintaining a sufficient gap G, and a discharge port 7 is formed at the bottom 6a thereof. The rotary tub 1 is supported by a bearing 8 at the bearing 4 together with the bottom 6a of the fixed tub 6. The gantry 8 has a base 8 in the lower left portion by a hinge 8a in the example of FIG. It is provided so that it can stand upside down. For this undulation, although not shown, a driving force such as a cylinder or a feed screw mechanism is used.

  A drainage pipe 10 is connected to the discharge port 7 via a drainage coupling 10a so as to be connectable thereto, and here, a shutter-type on-off valve 11 is provided. 11a is an open / close drive source such as a solenoid of the valve 11.

  On the other hand, with respect to the rotary tank 1, a hollow shaft 12 having a hollow inside from above is disposed so as to be movable up and down. The hollow shaft 12 is provided with a plurality of hollow arms 13 extending in a radial direction or at least two directions with respect to the shaft in the vertical direction. It is preferable that the hollow arm 13 is provided with an inclination angle downward.

  A cutter 14 as a breaking means is provided at least at the tip of each hollow arm 13, preferably at the tip and the middle, and the hollow part of each hollow arm 13 is formed here up to the tip of the cutter 14 at the tip of the arm 13. In addition, a nozzle-like small hole is provided as a discharge port. A discharge port 13 a is also provided in the middle of each arm 13. As the cutter 14 in the present invention, a cutting fluid flow cutter or a thermal fusing cutter can be used in addition to the blade. Moreover, the system which bursts the pack body P accommodated with the mechanical press force can also be taken.

  A water supply pipe 16 is connected via a rotary joint 15 at least above the rotary tank 1 of the hollow shaft 12. Here, the water supply pipe 16 is connected to the rotary joint 15 via a water supply coupling 16a, and includes a valve 16b in front of the coupling 16a.

  The upper portion of the hollow shaft 12 is supported by a shaft support mechanism 17 that also serves as an elevating mechanism for holding the shaft 12 so as to be movable up and down. The elevating mechanism is formed by a rack equipped with a motor, pinions 17a and 17b and a feed screw or a cylinder (not shown), and a shaft support mechanism is used for the rack and pinions 17a and 17b, or a linear slide (not shown) A mechanism is used. As described above, an example of a processing apparatus used in the method of the present invention is formed.

The processing apparatus of an example for implementing the method of the present invention formed as described above is used as follows.
First, the lids 1b and 1c at the top of the rotating tub 1 are opened, and the hollow shaft 12 is raised by driving its elevating mechanism 17, and each hollow arm 13 of the shaft 12 is retracted above the rotating tub 1. To. At this time, if there is a situation such as the length of the water supply pipe 16 being insufficient, the water supply pipe 16 and the rotary joint 15 of the shaft 12 are separated by the coupler 16a.

  When the lids 1b and 1c are opened and there is nothing in the tank as described above, a plurality of collected excrement packs P are put into the rotary tank 1. The input amount of the pack body P is about 1/2 to 1/3 of the volume of the tank 1, and in this state, the motor 5 is started and the rotating tank 1 is switched to one side or the forward and reverse directions at a relatively low speed. Rotate with

  During the rotation of the tank 1, the elevating mechanism 17 is activated to lower the hollow shaft 12, and gently lower until each hollow arm 13 is positioned inside the rotating tank 1. When the hollow shaft 12 enters the tank 12 during the rotation of the rotary tank 1, each pack body P that touches or approaches the tip 14 of each hollow arm 13 or the cutter 14 attached in the middle thereof has its outer skin. Is broken or torn by the cutter 14, so that the excrement inside begins to flow into the tank.

  In this state, or when water is supplied by opening the valve 16b from the water supply pipe 16 connected to the rotary joint 15 via the coupler 16a before that time, the water passes through the rotary joint 15. Then, it flows down through the hollow passage of the hollow shaft 12 and is discharged vigorously into the rotary tank 1 from the discharge port 13a of each hollow arm 13 or the discharge port 14a provided at the tip of the cutter 14 or the like.

The excrement flowing out from the pack body P that has been cut or broken inside the rotary tank 1 due to the water discharge is further discharged from the pack body P due to the rotation of the rotary tank 1. While the pack P does not flow out from the water permeable part 2 to the fixed tank 6 side from the water permeable part 2 by a mesh or a small hole provided in the tank 1, the inside of the rotary tank 1 Remain in.
That is, in the rotating rotator 1, after the pack body P and the excrement sealed and housed therein are separated and separated in the rotator 1, the excrement is separated from the rotator 1. The pack body P remains in the rotary tank 1 and is separated. For this reason, the rotation of the rotary tank 1 at the time of water discharge is preferably a high-speed rotation. Further, when water is discharged, the rinsing effect is enhanced by moving the hollow shaft 12 up and down.

  Thus, by rotation of the rotating tank 1 and supply of water therein, the pack body P remaining inside the rotating tank 1 is sufficiently rinsed to remove the deposit of dirt, and this tank 1 The excreta inside is discharged from the water permeable part 2 to the fixed tank 6.

  The excrement discharged to the fixed tank 6 is discharged to the drain pipe 10 through the discharge port 7 where the on-off valve 11 is opened, and is transferred to an existing sewer or septic tank (not shown).

  On the other hand, the pack P that has been broken inside the rotary tank 1 and has been rinsed with water to remove the deposits, stops the rotation of the tank 1, opens the lids 1b and 1c, and opens the hollow shaft 12 to the tank. When raised to the outside, this processing apparatus is laid down on the base 8 with the hinge 8a on the base 8, and the pack body P inside the rotary tank 1 is scraped out, which is incombustible waste or industrial waste. Dispose of it with existing equipment.

  The method of the present invention collects the above-mentioned excrement-packed pack body, repeats the separation of the pack body and excrement by the above-described processing apparatus, and the separation of both after separation, thereby allowing general households, hospitals, etc. The pack body enclosing the excrement collected at the facility can be treated rationally and labor-saving.

  Further, according to the method of the present invention, the pack body and excrement separated and separated by the processing apparatus can be finally processed separately in existing processing facilities and equipment, so that new equipment for processing, etc. Therefore, it is possible to treat the excrement enclosed in the pack body that is stored in the portable toilet without providing a toilet.

  The above-described method of the present invention has a capacity to be installed not only in a pack body enclosing excrement collected in a portable toilet for personal use installed in a facility such as a general home or a hospital, but also in an event venue or a construction site. It can also be applied to the treatment of a large amount of packed excrement accumulated in a large temporary toilet facility.
