Description

TECHNICAL FIELD The present invention relates to a used paper diaper processing apparatus that reduces the weight of a used paper diaper by separating water from a superabsorbent polymer contained in the used paper diaper.

More specifically, the present invention reduces the water absorption function of the superabsorbent polymer by mixing the superabsorbent polymer that has absorbed the water contained in the excrement with a chemical containing divalent metal ions or the like. The present invention relates to a used paper diaper processing apparatus for reducing the weight of a used paper diaper by dehydrating the used paper diaper after the moisture content of the used paper diaper is reduced.

Since used paper diapers contain a large amount of water, their weight can be a problem when handling a large amount of used paper diapers in nursing homes or the like. Disposable diapers contain superabsorbent polymers and are capable of retaining a large amount of water. In addition, once the water is absorbed by the super absorbent polymer, it is difficult to release the water as it is.

Therefore, the used paper diaper soaked in water is separated and dismantled into water-soluble matter and insoluble matter, and the separated and disassembled water-soluble matter is discharged to the sewage treatment facility side together with wastewater, thereby reducing the weight and volume of the paper diaper. A used disposable diaper processing apparatus has been proposed (see Patent Document 1).

FIG. 10 shows an example of a conventional used paper diaper processing apparatus 101 described in Patent Document 1, and FIG. 10(a) is a front view of the conventional used paper diaper processing apparatus 101. FIG. 10(b) shows a side view. 10, 102 is an opening/closing lid, 106 is an outer body, 107 is a rotating drum, 111 is a through hole, 112 is a stirring protrusion, 116 is a motor, 133 is a water supply pipe, 135 and 137 are discharge pipes, and 136 is an opening/closing valve. is.

Next, the operation of the conventional used paper diaper processing apparatus 101 will be described.

Used paper diapers are put into the rotary drum 107 from the opening/closing lid 102 .

Next, after a predetermined amount of water (i.e., an amount for submerging the lower portion of the rotary drum 107) is supplied from the water supply pipe 133 into the outer drum 106, the motor 116 is started to rotate the rotary drum 107, thereby rotating the rotary drum. A water flow is generated in 107 . This makes it possible to separate and dismantle the paper diapers in the rotating drum 107 while they are immersed in water. At this time, the presence of the stirring protrusions 112 promotes the stirring process of the disposable diaper, thereby promoting the separating and dismantling process. The separated and dismantled paper diapers pass through the discharge pipes 135 and 137 through the through holes 111 and are discharged to the sewage pipe communicating with the sewage treatment facility.

However, in the used paper diaper processing apparatus 101 described in Patent Document 1, the paper diapers are separated and dismantled in the processing process, and the fiber components of the dismantled paper diapers are directly discharged to the sewage treatment facility. There is a problem that the load for processing the fiber components of dismantled paper diapers increases in the wastewater treatment of the wastewater treatment. Therefore, when discharging into a sewage pipe, it is necessary to introduce a device for filtering out the fiber components of dismantled paper diapers.

Therefore, as another treatment method, a used paper diaper treatment apparatus has been proposed that reduces the weight of paper diapers by reacting with a chemical containing divalent metal ions or the like to separate the water from the superabsorbent polymer (Patent Reference 2).

FIG. 11 shows an example of a conventional used paper diaper processing apparatus 201 described in Patent Document 2. As shown in FIG. In FIG. 11, 202 is lime, 203 is hypochlorous acid, 204 is a treatment tank, 205 is a used paper diaper, 206 is water, 207 is liquid, and 208 is wastewater.

Next, the operation of the conventional used paper diaper processing apparatus 201 will be described.

First, as shown in (a) of FIG.

Next, as shown in FIGS. 11(b) and 11(c), water 206 is poured into the treatment tank 204 so that it can be stirred, and then stirred for a predetermined period of time. If stirring is continued in this state, the Ca ions contained in the lime react with the superabsorbent polymer of the disposable diaper, and the water contained in the superabsorbent polymer is released.

Finally, as shown in (d) of FIG. 11, the liquid 207 in the processing bath 204 is drained out of the processing bath 204 and dehydrated, and the waste water 208 is discharged.

Japanese Patent Application Laid-Open No. 2001-104929 JP 2010-84031 A

However, in the used paper diaper processing apparatus 201 described in Patent Document 2, dehydration is performed after the water contained in the superabsorbent polymer is released in the processing tank 204, and only the paper diaper portion is in the processing tank 204. It is designed to remain. In order to take out the remaining used paper diapers, it is necessary for the operator to take it out from above, and it is necessary to repack the used paper diapers that have been taken out into disposal bags such as plastic bags. A problem arises that imposes a work burden and a hygiene burden on the staff.

In view of these points, the present invention agitates used paper diapers together with chemicals containing divalent metal ions and the like to lower the water absorption function of the superabsorbent polymer, thereby releasing water. , in a used paper diaper processing apparatus that reduces the weight of used paper diapers by reducing the amount of moisture contained in the used paper diapers by performing dehydration, the weight reduction processing is performed without separating and dismantling the paper diapers, and the used paper diapers are taken out after processing. By realizing the series of operations in the treatment equipment, used paper diaper treatment reduces the work burden and hygiene burden on workers in nursing care facilities without increasing the burden of wastewater treatment at sewage treatment plants. The purpose is to provide an apparatus.

In order to solve the above problems, a used disposable diaper processing apparatus according to one aspect of the present invention includes a processing tank for processing used disposable diapers,
a liquid supply unit that supplies a processing liquid to the processing tank;
a liquid discharge unit for discharging the processing liquid from the processing tank;

[Embodiment 1]
Hereinafter, a used paper diaper processing apparatus 1 according to an embodiment of the present invention will be described in detail with reference to the drawings. The same or corresponding parts in the drawings are denoted by the same reference numerals, and the description thereof will not be repeated. In addition, in order to make the description easier to understand, in the drawings referred to below, the configuration is shown in a simplified or schematic form, or some constituent members are omitted. Also, the dimensional ratios between the constituent members shown in each drawing do not necessarily indicate the actual dimensional ratios.

[overall structure]
First, the overall configuration of the used paper diaper processing apparatus 1 will be described. FIG. 1A is a side cross-sectional view showing the configuration of the used paper diaper processing apparatus 1 according to Embodiment 1 of the present invention.

The used paper diaper processing apparatus 1 includes at least a processing tank 20 , a liquid supply section 10 , a liquid discharge section 9 and an extraction section 6 . More specifically, the used disposable diaper processing apparatus 1 further includes an input door 2 , an apparatus main body 3 , a storage container 7 , a disposal bag 8 , a control device 11 and a rotation drive section 70 .

A processing tank 20 for processing used paper diapers is disposed in the upper part of the apparatus main body 3, and is composed of, for example, a circular cylindrical outer tank 4 and a circular cylindrical inner tank 5, for example. The inner tub 5 is arranged inside the outer tub 4 .

The upper portion of the inner tank 5 is an upper conical portion 5b configured as a wide mouth portion to facilitate insertion of the used paper diaper 18, the intermediate portion is a cylindrical portion 5c continuing to the upper conical portion 5b, and the lower portion is a cylindrical portion. It is configured to form a conical tapered portion 5d that narrows toward the bottom from 5c.

The outer tank 4 has a cylindrical portion 4c from the upper portion to the intermediate portion, and a lower portion has a conical tapered portion 4d tapered from the cylindrical portion 4c toward the bottom surface in the same manner as the conical tapered portion 5d. is configured to

A plurality of rectangular plates 73 are attached to the inner surface of the inner tank 5 around the center of the inner tank as an example of sticking prevention members on the inner side surface of the inner tank 5 . The upper end of the plate 73 is connected to the inner tank 5 at the upper end of the inner side surface of the upper cylindrical portion 5c of the inner tank 5. The plate 73 is separated from the inner tank 5 toward the center of the inner tank as it goes downward, and the lower end is free. It is attached to the end. Therefore, the plate 73 is in contact with the inner surfaces of the cylindrical portion 5c and the tapered portion 5d of the inner tank 5 due to the centrifugal force during the dehydration operation, which will be described later. , i.e., the state of being spaced apart from the inner tank 5 towards the center of the inner tank as it goes downward. In other words, the plate 73 is supported by the inner tub 5 and configured to regulate the position of the stored used paper diaper 18 away from the inner surface of the inner tub 5 .

The input door 2 is attached to the upper part of the apparatus main body 3 so that it can be opened and closed. The used paper diaper 18 is thrown into the inner tank 5 by opening the throw-in door 2 .

The outer tank 4 is a container capable of storing water. Water can be stored by introducing water into the outer tank 4 from the liquid supply unit 10, and the medicine can also be supplied from the liquid supply unit 10. It can be introduced into tank 4 . As a result, the processing liquid 19 can be supplied from the liquid supply unit 10 into the outer tank 4 . Although the details will be described later, the processing liquid 19 in which water and chemicals are mixed can be supplied from the liquid supply section 10 into the outer tank 4 .

Also, the liquid in the outer tank 4 is discharged to the outside using the liquid discharge part 9 . Inside the outer tank 4, a cylindrical inner tank 5 having a plurality of through holes 5a at least on either side or bottom is arranged.

In addition, the inner tub 5 is rotatably connected to the rotation drive section 70 . The rotation driving section 70 is driven under the control of the control device 11 . As an example, the rotation drive unit 70 includes a shaft 13 fixed to the inner tank 5 along the rotation axis of the inner tank 5, a belt 14 that engages with the shaft 13 to rotate the shaft 13, and a belt 14 that engages with the belt 14. The inner tub 5 can be rotated with respect to the outer tub 4 by driving the motor 12 under the control of the control device 11 . As an example, the rotation axis of the inner tank 5 can be arranged along the vertical direction.

The outer tank bottom part 15 and the inner tank bottom part 17 can be opened and closed around the rotation axis by hinge parts 71 and 72 as an example of the opening/closing parts with respect to the outer tank 4 and the inner tank 5, respectively. It's becoming A take-out part 6 is arranged in the lower part of the device main body 3 below the outer tank bottom part 15 and the inner tank bottom part 17 .

The treated paper diaper can be taken out from the taking-out part 6. - 特許庁A storage container 7 to which a disposal bag 8 is attached is arranged inside the take-out part 6 . The disposal bag 8 is arranged directly below the inner tank bottom 17 . By making the opening of the storage container 7 larger than the opening of the bottom of the inner tank 5 , the paper diapers after treatment can be smoothly dropped into the disposal bag 8 of the storage container 7 .

The lower portions of the outer tub 4 and the inner tub 5 do not have to have tapered portions 4d and 5d as shown in FIG. 1B. By providing the tapered portions 4d and 5d, it is possible to reduce the diameters of the outer tank bottom portion 15 and the inner tank bottom portion 17, and the hinge portions 71 and 72 provide the space necessary for opening and closing around the rotation axis. can be made smaller. As a result, more diapers after treatment can be stored in the container 7 .

[motion]
Next, the processing operation of the used paper diaper processing apparatus 1 will be described. In the following, for convenience of explanation, the state in which the used paper diapers 18 are placed in the inner tank 5 and then stirred (FIG. 2) and the state in which the inner tank 5 is rotated at high speed for dehydration are described. 3) and the state in which the outer tank bottom 15 and the inner tank bottom 17 are opened and the treated used paper diaper 18 is taken out to the take-out part 6 (FIG. 5). do.

In FIG. 2, water is introduced into the outer tank 4 from the liquid supply unit 10, and a certain amount of water is stored in the outer tank 4. As shown in FIG.

Next, a chemical that lowers the water absorbing function of the superabsorbent polymer is introduced into the outer tank 4 from the liquid supply unit 10 and mixed with the water that has already been introduced into the outer tank 4, resulting in a treatment liquid 19 in the outer tank 4. to store water. Agents that reduce the water absorption function of the superabsorbent polymer preferably contain metal ions, and in particular, calcium chloride or lime containing divalent metals can be used.

Next, the used paper diaper 18 is loaded into the inner tub 5 from the loading door 2, and the rotation of the motor 12 is controlled under the control of the controller 11 to perform the stirring operation. Specifically, when the motor 12 rotates, the shaft 13 rotates via the belt 14 and the inner tub 5 rotates with respect to the outer tub 4 . As a result, the treatment liquid 19 and the used paper diaper 18 are agitated. If the stirring operation is continued for a while (preferably about 5 minutes to 30 minutes), the superabsorbent polymer of the used paper diaper 18 reacts with, for example, divalent metal ions in the drug, and the superabsorbent polymer is contained. The water that has been absorbed separates from the used paper diaper 18 , and the separated water is mixed with the treatment liquid 19 . In this stirring operation, the treatment liquid 19 and the superabsorbent polymer of the used paper diaper 18 should react with each other. Gentle stirring is important. Specifically, it is preferable to stir gently at, for example, 40 to 160 rpm.

It is possible to prevent the used paper diaper 18 from swelling in the inner tank 5 by putting the used paper diaper 18 into the outer tank 4 while the treatment liquid 19 mixed with the medicine is stored in the outer tank 4 . If the used paper diaper 18 is put in a state in which only water is stored without storing the treatment liquid 19 containing the drug, the superabsorbent polymer absorbs the water and the used paper diaper 18 expands greatly. In this case, there arise the problem that the number of used paper diapers 18 that can be put into the inner tank 5 at one time is limited, and the problem that the inner tank 5 must be enlarged. On the other hand, if the treatment liquid 19 mixed with chemicals is stored in the outer tank 4, the occurrence of these problems can be suppressed.

Next, the dewatering operation of the used paper diaper 18 will be described with reference to FIG. After the liquid such as the processing liquid accumulated in the outer tank 4 is discharged from the liquid discharge part 9, the used paper diaper 18 can be dehydrated by rotating the inner tank 5 with respect to the outer tank 4 at high speed. , the used paper diaper 18 can be reduced. Specifically, it is preferable to dehydrate at about 800 to 1300 rpm. At this time, the used paper diaper 18 is pushed outward within the inner tub 5 by centrifugal force. Adhesive is used in the paper diaper 18, and when the treatment operation is performed continuously, the dissolved adhesive adheres to the inside of the inner tank 5, and after dehydration, the inner tank 5 and the used paper diaper 18 are separated. may stick with adhesive. When the tapered portion 5d is provided in the lower portion of the inner tank 5, there is a tendency that the tapered portion 5d is especially likely to stick. However, a plate 73 is attached inside the inner tub 5, and the plate 73 is also pressed against the side surface and elastically bent by centrifugal force during dehydration. When the dewatering operation is completed, the curved plate 73 tries to return to its original position because the centrifugal force disappears. With this force, the used paper diaper 18 sticking to the side surface of the inner tub 5 is peeled off.

The interval between the plates 73 is preferably 3 to 15 cm, for example (see FIG. 4(a)). In this case, it is possible to remove the used paper diaper 18 from the inner tub 5 . If the spacing between the plates 73 is less than 3 cm, the used paper diaper 18 may be caught between the plates 73 due to centrifugal force during dehydration, and the used paper diaper 18 may not drop from the inner tub 5 . On the other hand, if the spacing between the plates 73 is more than 15 cm, the used paper diaper 18 may get stuck between the plates 73 and may not be peeled off (see FIG. 4(b)).

The width of the plate 73 is preferably 1 to 5 cm, for example. If the width of the plate 73 is less than 1 cm, the plate 73 lacks the force to remove the stuck used paper diaper 18 from the inner tub 5 . If the width of the plate 73 exceeds 5 cm, the used paper diaper 18 sticks to the plate 73 itself, and the used paper diaper 18 may not drop from the inner tank 5 .

As the material of the plate 73, vinyl chloride or the like having high elasticity and being hard to break is preferable. In this case, the thickness of the plate 73 is preferably 1 to 3 mm, for example. If the thickness of the plate 73 is less than 1 mm, the elastic force of the plate 73 will be insufficient, and the force for peeling off the stuck used paper diaper 18 will be insufficient. If the thickness of the plate 73 exceeds 3 mm, the elastic force of the plate 73 is too strong, and the used paper diaper 18 sticking to it may not be peeled off from the inner tub 5 because it does not bend.

Next, the operation of taking out the used paper diaper 18 will be described with reference to FIG. When the outer tub bottom 15 and the inner tub bottom 17 are opened via the hinges 71 and 72 after dewatering, the used paper diaper 18 drops into the disposal bag 8 installed in the storage container 7 . When the used paper diaper 18 is to be discharged, it can be discharged by simply taking it out of the device main body 3 by sliding the take-out part 6 laterally with respect to the device main body 3 and taking out the disposal bag 8 from the storage container 7. becomes.

According to the first embodiment described above, the paper diaper 18 that has undergone weight reduction treatment with a chemical containing metal ions or the like is not separated and disassembled in the treatment tank 20, and the fiber portion remains. In addition, there is no need for the operator to directly take out the paper diaper 18 after treatment from above the inner tank, and it can be stored in the disposal bag 8 without troubling the operator. burden can be reduced.

Although the disposal bag 8 for disposal is installed in the storage container 7 in the first embodiment, the disposal bag 8 may not be installed and the storage container 7 may be directly stored.

Further, instead of preparing the treatment liquid 19 by adding chemicals containing metal ions after storing water in the outer tank 4, the treatment liquid 19 is previously prepared by mixing water and chemicals. Alternatively, the prepared treatment liquid 19 may be stored directly in the outer tank 4 .

It is also possible to rotate the inner tub 5 directly by the motor 12 without using the belt 14 .

[Embodiment 2]
FIG. 6 shows the device configuration of Embodiment 2 of the present invention.

In Embodiment 1, the plate 73 is composed of one plate. Therefore, when pressed by centrifugal force, a gap 90 is formed between it and the tapered portion 5d. FIG. 7 shows a cross-sectional view taken along the IV-IV line in FIG. 3 showing the dewatering operation of the first embodiment. When the used paper diaper 18 is pushed by the centrifugal force during the dehydration operation, the used paper diaper 18 is pushed into the gap 90 formed between the inner tank 5 and the plate 73 and wraps around to the back side of the plate 73 . As a result, the used paper diaper 18 may not fall out of the inner tub 5 due to the tension force F even after the dewatering operation is completed.

Therefore, the difference from the first embodiment is that a short plate 75 extending further downward is attached to the lower end of each plate 73 via a hinge portion 74 .

In this way, by attaching the short plate 75 movable by the hinge portion 74 to the lower end portion of each plate 73 so that the gap 90 between the inner tank 5 and each plate 73 is eliminated, the short plate 75 is tapered. 5d so that the plate 73 or the short plate 75 can come closer to the tapered portion 5d, narrowing the gap between the inner tank 5 and the plate 73. can do. As a result, the used paper diaper 18 can be effectively prevented from entering the gap 90 between the inner tank 5 and the plate 73, and the used paper diaper 18 can be peeled off from the inner tank 5 more reliably. be.

According to the configuration of the second embodiment, the hinge portion 74 is bent during the dewatering operation, so that the gap between the inner tub 5 and the plate 75 is eliminated, and the used paper diaper 18 is prevented from being pushed in and wrapped around the back side of the plate 75 . , the used paper diaper 18 can be reliably peeled off (see FIG. 8).

According to the second embodiment described above, the plate 73 and the short plate 75 are bent via the hinge portion 74 by the centrifugal force during the dehydration operation, and the used paper diaper is bent along the inner surface of the inner tank 5. 18 can be more reliably peeled off from the inner tank 5.例文帳に追加

[Embodiment 3]
FIG. 9 shows the device configuration of Embodiment 3 of the present invention.

In Embodiments 1 and 2, the plurality of plates 73 are separated from each other. It differs from forms 1 and 2.

In this manner, the net 76 is stretched between the adjacent plates 73 to regulate the position of the used paper diaper 18 so as to separate it from the inner surface of the inner tub 5 . With such a configuration, even if the used paper diaper 18 is positioned between the adjacent plates 73, the net 76 allows the used paper diaper 18 to be more reliably peeled off from the inner tank 5. becomes.

By adopting such a configuration, the used paper diaper 18 is pressed by centrifugal force during the dehydration operation, and the used paper diaper 18 is pushed into the gap between the adjacent plates 73 and 73 to the back side of the plate 73. It is possible to avoid the problem that the wraparound is about to occur.

According to the third embodiment described above, even if the used paper diaper 18 is pushed by the centrifugal force during the dehydration operation and pushed into the gap between the adjacent plates 73, The mesh 76 between the adjacent plates 73 makes it possible to more reliably tear off the used paper diaper 18 that has been pushed in from the inner tub 5 .

As described above, according to the used disposable diaper disposal apparatus according to Embodiments 1 to 3, the bottom of the outer tank 5 and the bottom of the inner tank 4 can be opened and closed, and the sticking prevention device disposed on the inner surface of the inner tank The dehydrated diaper can be peeled away from the inner surface of the inner tank with a member plate 73 or the like, and the treated diaper can be dropped from the inner tank 4 and taken out from below the inner tank 4. It is possible to reduce burden and hygiene burden.

Although the embodiments of the present invention have been described above, the above-described embodiments are merely examples for carrying out the present invention. Therefore, the present invention is not limited to the above-described embodiment, and can be implemented by appropriately modifying the above-described embodiment without departing from the scope of the invention.
