A sanitary product processing apparatus 1 according to this embodiment is mainly for processing used sanitary products, that is, sanitary products to which dirt or the like is adhered. The sanitary articles to be treated consist mainly of pulp fibres. The type of pulp fiber is not particularly limited, but pulp fiber, fluff-like pulp fiber, chemical pulp fiber and the like can be exemplified.

Moreover, the sanitary article to be treated contains a water absorbing material. The water absorbing material is, for example, a polymer absorbing material. Polymeric absorbents are also called superabsorbent polymers (SAPs). The polymer absorbent material has a three-dimensional network structure in which water-soluble polymers are moderately crosslinked. The polymer absorbent material absorbs several hundred times to a thousand times more water, but is essentially water-insoluble, and the water once absorbed does not separate even if some pressure is applied. Although the type of polymer absorbent is not particularly limited, starch-based, acrylic acid-based, and amino acid-based particulate or fibrous polymers can be exemplified. Examples of sanitary products to be treated include disposable paper diapers, incontinence pads, sanitary napkins, panty liners, and the like.

A sanitary goods processing apparatus 1 according to this embodiment includes a processing bath 30 as shown in FIG. The processing tank 30 has a container-like shape with an inlet 31 formed on the upper surface thereof. Sanitary products to be treated can be put into the space inside the treatment tank 30 through an inlet 31 . When the sanitary goods to be treated are, for example, used paper diapers, the used paper diapers contain a water absorbing material. In other words, sanitary products containing absorbent materials are accumulated inside the treatment tank 30 .

In addition, a lid portion may be provided on the upper surface of the processing bath 30 to close the input port 31 in an openable and closable manner. When a lid is provided, the lid is basically kept closed while sanitary goods are being processed by the sanitary goods processing apparatus 1 . When the sanitary goods to be treated are put into the treatment tank 30, the lid is opened.

A water supply pipe 10 is attached to the processing tank 30 . One end of the water supply pipe 10 is connected to the processing bath 30 . The other end of the water supply pipe 10 is connected to a water supply (not shown). Tap water can be introduced into the processing tank 30 through the water supply pipe 10 . A water supply valve 11 is provided on the water supply pipe 10 . By opening and closing the water supply valve 11, it is possible to supply water to the processing bath 30 and stop the supply. Opening and closing of the water supply valve 11 is performed under the control of the control device 12 . A wiring 13 is connected to the control device 12 . The wiring 13 supplies electric power necessary for the operation of the control device 12 from an external source such as a commercial power source. The water supply pipe 10 configured as described above is an example of water supply means for supplying water into the processing bath 30 .

A crushing unit 32 is provided inside the processing tank 30 . A turntable 33 is provided inside the crushing processing unit 32 . The turntable 33 has, for example, a disc-shaped outer shape. The turntable 33 is driven by a motor 34 to rotate. The rotating shaft of the turntable 33 is arranged in the vertical direction. Moreover, the upper surface of the turntable 33 is arranged horizontally. The inner peripheral wall of the crushing processing section 32 has a cylindrical shape around the rotating shaft of the turntable 33 .

The inner peripheral wall of the crushing section 32 is provided with sharp projections or blades (not shown) for cutting and crushing sanitary products. When the turntable 33 is rotated by the motor 34 while the sanitary goods to be processed are placed on the turntable 33, the sanitary goods are moved to the turntable 33 by the centrifugal force acting on the sanitary goods on the turntable 33. It is thrown toward the radially outer side, that is, toward the inner peripheral wall of the crushing processing section 32 . The thrown sanitary goods collide with the sharp projections or blades on the inner peripheral wall of the crushing section 32 and are torn, cut and crushed.

Specifically, for example, in the process of crushing a paper diaper containing a water-absorbing material, the topsheet of the paper diaper is first broken. Then, the water-absorbing material (water-absorbing polymer) contained in the pulp (fiber) inside the paper diaper leaks out. In a used paper diaper, the water-absorbing polymer becomes gel by absorbing water contained in excrement and the like. After that, as the crushing progresses further, the relatively hard sheet material is broken into fine pieces into crushed pieces.

The crushing processing unit 32 including the turntable 33 , the motor 34 and the inner peripheral wall configured as described above is an example of cutting means for cutting the sanitary goods in the processing tank 30 . Control of the cutting means, more specifically, operation control of the motor 34 of the turntable 33 is performed by the control device 12, for example.

A rotary blade may be provided in the crushing processing section 32 as the cutting means. Specifically, for example, a blade that rotates together with the turntable 33 is provided on the upper surface of the turntable 33 or the like. Alternatively, the inner peripheral wall of the crushing processing unit 32 is made rotatable in the processing tank 30, and a blade that rotates together with the inner peripheral wall is provided on the inner peripheral wall of the crushing processing unit 32. By providing such a rotary blade, it is possible to improve the cutting ability and crushing ability of the crushing processing section 32 as the cutting means.

A plurality of holes (not shown) are formed in the inner peripheral wall of the crushing section 32 . These holes penetrate the inner peripheral wall of the crushing section 32 . These holes may be holes such as elongated slits or holes formed in a mesh shape. As will be described later, water is supplied from the water supply pipe 10 into the processing tank 30 while the turntable 33 is rotating. The water supplied into the processing tank 30 is blown toward the radially outer side of the turntable 33 , that is, toward the inner peripheral wall of the crushing processing section 32 by centrifugal force. The blown water passes through the holes of the crushing section 32, goes out of the crushing section 32, and falls downward.

A first storage section 35 is provided below the crushing processing section 32 inside the processing tank 30 . The sanitary goods cut by the cutting means and water are mixed and stored in the first reservoir 35 . In the configuration example described here, the first reservoir 35 is provided at the lowest part in the processing bath 30 .

A processing bath outlet 36 is formed in the processing bath 30 . The treatment tank discharge port 36 is an opening for discharging the water in the first reservoir 35 and the cut sanitary goods to the outside of the treatment tank 30 . Therefore, the processing bath discharge port 36 communicates with the first reservoir 35 in the processing bath 30 .

The sanitary goods processing apparatus 1 according to this embodiment further includes a storage tank 40 . The inflow side of the storage tank 40 is connected to the treatment tank discharge port 36 via a connecting pipe 37 . The inside of the reservoir 40 is a second reservoir 41 . The second reservoir 41 stores the water discharged from the treatment tank discharge port 36 and the cut sanitary products. That is, in the second reservoir 41 as well as in the first reservoir 35, the sanitary goods cut by the above-described cutting means and water are stored in a mixed state.

The first storage portion 35 and the second storage portion 41 configured as described above are storage portions for storing the sanitary goods cut by the above-described cutting means and water in a mixed state. At least one of the first storage portion 35 and the second storage portion 41 may be provided as the storage portion.

One end of the drain pipe 20 is connected to the discharge side of the storage tank 40 . The other end of the drain pipe 20 communicates with sewage. The connection pipe 37 , storage tank 40 and drain pipe 20 form a discharge path for discharging sanitary products and water treated in the treatment tank 30 .

In the configuration example described here, a partition wall 42 is formed inside the storage tank 40 . A partition wall 42 is provided between the inflow side and the outflow side of the storage tank 40 . The top of partition wall 42 is connected to the inner wall of storage tank 40 . A gap is formed between the lowermost portion of the partition wall 42 and the inner wall of the storage tank 40 . Both sides of the storage tank 40 across the partition 42 are connected through this gap.

The location of the outlet from reservoir 40 is lower than the inlet to reservoir 40 . In the configuration example described here, the inlet to the storage tank 40 and the outlet from the storage tank 40 are positioned above the center of the storage tank 40 in the vertical direction. However, the positions of the inflow port to the storage tank 40 and the outflow port from the storage tank 40 do not have to be above the middle of the storage tank 40 in the vertical direction as long as they are above the gap of the partition wall 42 . In the storage tank 40 configured as described above, when the inflow of water or the like from the connecting pipe 37 stops, the water level in the storage tank 40 changes to the height of the outflow port from the storage tank 40 as shown in FIG. , and the discharge path described above is water-sealed. In this manner, the storage tank 40 is formed with a trap structure for water-sealing the discharge path described above. Note that the trap structure does not necessarily have to be provided.

As a modification, the reservoir 40 having the second reservoir 41 may have a pipe trap structure as shown in FIG.

Next, the operation of the sanitary goods processing apparatus 1 of this embodiment will be described with reference to FIGS. 3 and 4. FIG. FIG. 3 shows the elapsed time from the start of the sanitary goods crushing process in the treatment tank 30, the remaining amount of sanitary goods in the crushing unit 32 (hereinafter also referred to as the "remaining amount of treatment") and the treatment tank. It is the relationship with the flow rate of water supplied from the water supply pipe 10 to the crushing processing unit 32 of 30 .

As described above, opening and closing of the water supply valve 11 of the water supply pipe 10 is controlled by the controller 12 . The sanitary goods processing apparatus 1 of this embodiment intermittently opens and closes the water supply valve 11 . That is, the aforementioned water supply means intermittently supplies water into the treatment tank 30 after the aforementioned cutting means starts cutting the sanitary goods. A case will be described below in which the water supply is stopped before the sanitary goods are cut by the cutting means, and water is intermittently supplied into the treatment bath 30 after the cutting is started. However, the intermittent water supply to the processing tank 30 may be performed at least after the sanitary goods are cut by the cutting means, and the water supply may be performed intermittently or continuously before the start of cutting. do not have.

Specifically, in the example shown in FIG. 3 , when sanitary products are put into the processing tank 30 and processing is started, the control device 12 starts cutting and crushing processing in the crushing processing section 32 . That is, the control device 12 rotates the turntable 33 by the motor 34 . At the start of the cutting and shredding process, the water supply valve 11 is closed. That is, the water supply to the inside of the processing tank 30 is stopped.

After a preset time t1 has elapsed since the turntable 33 started to rotate, the controller 12 opens the water supply valve 11 to start supplying water to the processing bath 30 . At this time, the opening of the water supply valve 11 is set so that the flow rate of water supplied into the processing tank 30 is Q1. In this example, the turntable 33 continues to rotate even during water supply.

After a preset time t2 has elapsed since the start of water supply, the controller 12 closes the water supply valve 11 to stop the water supply into the processing bath 30 . After the above-described time t1 has elapsed since the water supply to the processing bath 30 was stopped, the control device 12 reopens the water supply valve 11 and restarts the water supply to the processing bath 30 . After the time t2 has passed, the control device 12 closes the water supply valve 11 to stop the water supply to the processing bath 30 .

In this manner, water is intermittently supplied into the processing bath 30 at intervals of time t1. Then, intermittent water supply is repeated, and cutting and crushing processing in the crushing processing unit 32 is started. After a preset time t3 has passed, the inside of the processing bath 30 is finally cleaned. In this cleaning, the controller 12 opens the water supply valve 11 to supply water into the processing tank 30 . At this time, the opening of the water supply valve 11 is set so that the flow rate of water supplied into the processing tank 30 is Q2. The flow rate Q2 is greater than the aforementioned flow rate Q1. Also, the water supply time at this time is set to the preset time t4. Time t4 is longer than time t2 described above.

FIG. 4 is a flowchart showing the flow of operations of the sanitary goods processing apparatus 1 configured as described above. First, in step S<b>1 , sanitary goods to be treated, such as used paper diapers, are put into the treatment tank 30 . In the subsequent step S2, the crushing process is started. That is, the control device 12 operates the motor 34 to start cutting the sanitary goods in the crushing section 32 as the cutting means.

After step S2, in step S3, the control device 12 checks whether or not the above-mentioned time t1 has elapsed since the crushing process was started in step S2. If the time t1 has not passed since the crushing process was started, the process returns to step S2. On the other hand, when the time t1 has passed since the crushing process was started, the process proceeds to step S4.

In step S4, the controller 12 opens the water supply valve 11 and starts supplying water into the processing tank 30 at the flow rate Q1. After step S4, in step S5, the control device 12 confirms whether or not the above-described time t2 has elapsed since water supply was started in step S4. If the time t2 has not elapsed since the start of water supply, the process returns to step S4 to continue water supply. On the other hand, when the time t2 has elapsed since the water supply was started, the process proceeds to step S6.

In step S6, the controller 12 closes the water supply valve 11 to stop the water supply to the processing tank 30. FIG. After step S6, in step S7, the control device 12 checks whether or not the aforementioned time t3 has elapsed since the crushing process was started in step S2. If the time t3 has not passed since the crushing process was started, the process returns to step S2. On the other hand, when the time t3 has passed since the crushing process was started, the process proceeds to step S8.

In step S8, the controller 12 opens the water supply valve 11 and starts supplying water to the processing tank 30 at the flow rate Q2. This is the water supply for cleaning the inside of the processing bath 30 . After step S8, in step S9, the control device 12 checks whether or not the above-described time t4 has elapsed since water supply was started in step S8. If the time t4 has not elapsed since the water supply for washing was started, the process returns to step S8 to continue the water supply. On the other hand, when the time t4 has elapsed since the water supply for washing was started, the process proceeds to step S10.

In step S10, the control device 12 turns off the sanitary goods processing device 1. FIG. That is, the control device 12 stops the motor 34 to stop the cutting of the sanitary goods in the crushing section 32 as the cutting means. Further, the controller 12 closes the water supply valve 11 to stop the water supply to the processing tank 30 . When this step S10 is completed, a series of operations is completed.

According to the sanitary goods processing apparatus 1 configured as described above, water is intermittently supplied into the processing tank 30 after the cutting of the sanitary goods by the cutting means is started. For this reason, first, the amount of water in the processing bath 30 decreases while the water supply is stopped. Therefore, since the cutting means is operated when the amount of water in the crushing processing section 32 is small, the water absorbing material is efficiently removed without being affected by the water flow, the water pressure, and the water absorbing material whose viscosity has increased due to absorption of water. Cutting and shredding of sanitary products, including

In addition, sanitary goods and water are mixed and stagnant inside the processing tank 30 or the like between water supplies. Therefore, the water absorbing material contained in the sanitary goods can sufficiently absorb water, and the viscosity of the water absorbing material can be lowered to the extent that it can be discharged into the sewage system for domestic wastewater.

Since the flow rate of water per unit time can be increased while the total amount of water is kept small, the crushed sanitary goods can be washed away efficiently. Therefore, the amount of water required for treatment can be reduced. In addition, since the sanitary goods cut and crushed by the cutting means are gradually discharged little by little, clogging of the pipes or the like with the sanitary goods and the absorbent material can be suppressed during the discharging process. In this way, the sanitary goods containing the absorbent material can be treated in a relatively short period of time so that they can be discharged into the domestic sewage system.

In addition, in the reservoir (at least one of the first reservoir 35 and the second reservoir 41), the cut sanitary goods and water are mixed and stored, and then discharged out of the sanitary goods processing apparatus 1. Thus, it is possible to ensure the time required for the water absorbing material contained in the sanitary goods to reach a sufficiently diluted viscosity state (for example, saturated water absorption state). For this reason, it is possible to more reliably put the waste water into a state in which it can be discharged into the sewage system for domestic wastewater, and it is possible to suppress the clogging of the sewage system.

Note that the control of intermittent water supply to the processing tank 30 after the start of the sanitary goods crushing process is not limited to that described with reference to FIGS. 3 and 4 . Another example of intermittent water supply control to the processing bath 30 will be described below.

First, another example of intermittent water supply control will be described with reference to FIG. In this first example, the amount of water supplied is reduced as time elapses from the start of treatment. As shown in the figure, as the elapsed time from the start of the crushing process increases, the remaining amount of material to be processed decreases unless a new process target is added from the inlet 31 or the like. Therefore, the amount of water supplied from the above-described water supply means to the processing bath 30 is reduced in accordance with the decrease in the remaining amount of treatment.

Specifically, in the first water supply, the controller 12 sets the opening degree of the water supply valve 11 so that the flow rate of the water supplied into the processing bath 30 is Q1. In the second water supply, the controller 12 sets the opening degree of the water supply valve 11 so that the flow rate of water supplied into the processing tank 30 is Q1'. Q1'<Q1. The time t2 for opening the water supply valve 11 does not change. Also, although illustration is omitted, in the third water supply, the flow rate of water supplied into the processing tank 30 is set to Q1'' (<Q1'). Even in this way, the water-absorbing material contained in the sanitary goods remaining in the crushing processing section 32 is sufficiently absorbed, and the sanitary goods remaining in the crushing processing section 32 are drained into the first storage section 35. can be flushed with Therefore, it is possible to further reduce the amount of water required for the treatment.

Next, a second alternative example of intermittent water supply control will be described with reference to FIG. In this second alternative example, the time interval for supplying water is lengthened as time elapses from the start of treatment. As described above, the longer the elapsed time from the start of the crushing process, the smaller the remaining amount of processed material. Therefore, in accordance with the decrease in the remaining amount of treatment, the time interval (stopping time of water supply) for intermittently supplying water from the water supply means described above to the processing tank 30 is lengthened.

Specifically, the time interval from the start of the crushing process to the start of the first water supply is time t1. The time interval from the stop of the first water supply to the start of the second water supply is time t1'. t1'>t1. The time t2 for opening the water supply valve 11 does not change. Also, although illustration is omitted, the time interval from when the second water supply is stopped to when the third water supply is started is time t1'' (>t1'). Even in this way, the water-absorbing material contained in the sanitary goods remaining in the crushing processing section 32 is sufficiently absorbed, and the sanitary goods remaining in the crushing processing section 32 are drained into the first storage section 35. can be flushed with Therefore, it is possible to further reduce the amount of water required for the treatment.

Embodiment 2.
8 and 9 relate to Embodiment 2 of the present invention and are diagrams schematically showing the configuration of a storage tank of a sanitary goods processing apparatus.

Embodiment 2 described here is obtained by providing a drain valve in the reservoir in the configuration of Embodiment 1 described above. The sanitary goods processing apparatus according to the second embodiment will be described below, focusing on the differences from the first embodiment. The configuration whose description is omitted is basically the same as that of the first embodiment.

As shown in FIGS. 8 and 9, in the sanitary goods processing apparatus 1 according to this embodiment, a drain valve 43 is provided in a portion leading from the storage tank 40 to the drain pipe 20 . The drain valve 43 is a valve that opens and closes a portion that communicates with the storage tank 40 to the drain pipe 20 . When the drain valve 43 is closed, sanitary products, water, etc. in the storage tank 40 remain in the storage tank 40 without being discharged from the drain pipe 20 . When the drain valve 43 is opened, the contents inside the storage tank 40 can be discharged to the outside of the storage tank 40 together with the water through the drain pipe 20 .

A switch 44 is provided in the second reservoir 41 of the reservoir 40 . The drain valve 43 opens and closes in conjunction with the energized state of a terminal provided on the switch 44 . The terminal of the switch 44 is provided at the position of the water surface when the second reservoir 41 is at the reference water level. This reference water level is preset.

When the water level of the second reservoir 41 is lower than the reference water level described above, the terminals of the switch 44 do not come into contact with water, so the switch 44 is not energized. When the switch 44 is not energized, the drain valve 43 is closed. Then, as shown in FIG. 8, when the water level in the second reservoir 41 reaches or exceeds the reference water level, the terminal of the switch 44 touches the water and the switch 44 is energized. When the switch 44 is energized, the drain valve 43 opens. When the drain valve 43 opens, as shown in FIG. 9, the cut sanitary products and water in the second reservoir 41 are drained. Thus, the second reservoir 41 has a drain valve 43 that opens when the water level in the second reservoir 41 reaches or exceeds a preset reference water level.

The sanitary goods processing apparatus 1 configured as described above can also achieve the same effects as in the first embodiment. Furthermore, by providing a drain valve 43 that closes when the water level in the second reservoir 41 is less than the reference water level and opens when it reaches or exceeds the reference water level, the water level above the outflow port from the reservoir 40 can be reached. , water can be stored in the second reservoir 41 . Therefore, the volume of cut sanitary articles and water that can be stored in the second storage part 41 can be increased. Therefore, the water absorbing material contained in the sanitary goods can be made to absorb water until it reaches a sufficiently diluted viscosity state (for example, saturated water absorption state) more reliably.

In addition, since the position of the outflow port from the reservoir 40 can be lowered, the water level in the second reservoir 41 after the sanitary goods and water in the second reservoir 41 are discharged by opening the drain valve 43 is can be lower. Therefore, the capacity that can be newly received in the second reservoir 41 can be increased until the next reference water level is reached.

Embodiment 3.
FIG. 10 relates to Embodiment 3 of the present invention and is a diagram schematically showing the overall configuration of a sanitary article processing apparatus.

Embodiment 3 described here further includes deodorizing means for deodorizing the air in the treatment layer in the configuration of Embodiment 1 or Embodiment 2 described above. Hereinafter, the sanitary article processing apparatus according to the third embodiment will be described with a case based on the configuration of the first embodiment as an example, focusing on differences from the first embodiment. The configuration whose description is omitted is basically the same as that of the first or second embodiment.

The sanitary goods processing apparatus 1 according to this embodiment includes a deodorizing device 50 as shown in FIG. The deodorizing device 50 is deodorizing means for deodorizing the air in the processing tank 30 . A blower fan and a deodorizing filter (not shown) are provided in the deodorizing device 50 . A deodorizing filter is, for example, an activated carbon filter, a HEPA filter, or the like. Instead of the deodorizing filter, or together with the deodorizing filter, the deodorizing device 50 may be provided with a discharge deodorizer or the like.

The inside of the deodorizing device 50 communicates with the inside of the treatment tank 30 through an intake air passage 51 and a return air passage 52 . When the blower fan of the deodorizing device 50 operates, the air in the processing tank 30 is sucked into the deodorizing device 50 through the intake air passage 51 . The air sucked into the deodorizing device 50 has odor components removed by the above-described deodorizing filter or the like. Then, the air from which the odorous component has been removed is returned into the processing tank 30 through the return air passage 52 .

The sanitary goods processing apparatus configured as described above can also achieve the same effects as in the first or second embodiment. Furthermore, since the deodorizing device 50 is provided, it is possible to remove odorous components from the air in the processing tank 30. Therefore, when the cover of the processing tank 30 is opened and closed, the odor is prevented from leaking around the sanitary goods processing apparatus 1. can be suppressed.
