The recovery pipe 37 extends to the inside of the outer trunk separation tank 8. The collection pipe 37 communicates the drain receiving tank 34 and the outer trunk separation tank 8.

  The recovery pipe 37 adheres to waste water in the outer shell separation tank 8, that is, waste (sewage such as urine) decomposed from the used paper diaper 2 by the supplied decomposed water and contained in the polymer. The decomposed water mixed with filth and pulp that has been discharged is discharged into the drain receiving tank 34. The decomposed water containing the pulp drained into the drain receiving tank 34 is stored in the drain pit 35 through the drain pipe 36. The decomposed water stored in the drain pit 35 contains a large amount of pulp, and the pulp is separated and recovered by the pulp recovery device 38 from the decomposed water.

  As shown in FIG. 5, the pulp recovery device 38 includes a primary pit 39, a primary rotary screen 40a, a primary screw dewatering machine 42a, a drained pulp washing tank 41, a secondary rotary screen 40b, and a secondary screw dewatering machine. 42b. The primary pit 39 is fed by the pump 43 from the drain pit 35 with decomposed water in which pulp and filth (sewage) discharged from the inner trunk separation tank 9 are dissolved. By passing the drain pit 35 and the primary pit 39, large members mixed in the decomposed water are separated. The decomposed water from which the large members mixed through the drainage pit 35 and the primary pit 39 are separated is sent to the primary rotary screen 40a by the pump 44.

It is roughly structured. Since the secondary rotary screen 40b has the same configuration as the primary rotary screen 40a, description thereof is omitted.

  Decomposed water in which pulp and filth (sewage) are dissolved is introduced from the primary pit 39 into the screen drum 48 through the supply port 49. The primary rotary screen 40a separates the solid matter (pulp) in the decomposed water from the water of the decomposed water, and the water separated from the decomposed water is collected at the bottom of the housing 45 and collected. The pulp separated from the cracked water is sent to the primary screw dehydrator 42a. The pulp sent to the primary screw dehydrator 42 a is dehydrated and then sent to the drained pulp washing tank 41. In the drained pulp washing tank 41, the pulp is mixed with the washing liquid (water) and washed, and sent to the secondary rotary screen 40b by the pump 51. The washed pulp sent to the secondary rotary screen 40b is separated into solids (pulp) and washing liquid (water). The solid (pulp) separated from the cleaning liquid (water) is sent to the secondary screw dehydrator 42b, and the cleaning liquid (water) separated from the solid (pulp) is the same as the decomposed water recovered by the primary rotary screen 40a. To be recovered. The solid matter (water) containing moisture sent to the secondary screw dehydrator 42 b is dehydrated and collected in the collection tank 50.

And a pulp as a solid that did not dissolve in the cracked water remains.

  In the state where the inner trunk separation tank 9 is rotating, the used paper diaper is decomposed into pulp, plastic, filth decomposed from the polymer, etc. by supplying the decomposition water into the inner trunk separation tank 9. What is dissolved in the cracked water is discharged to the outside by the discharge unit 5, and solid matter that does not dissolve in the cracked water remains in the inner trunk separation tank 9. What is dissolved in the decomposed water is filth (sewage) from the pulp and polymer polymer, and these are discharged from the discharge section 5. In this case, since the pulp dissolved in the cracked water is discharged from the inner trunk separation tank 9 by the discharge section 5, the contents in the inner trunk separation tank 9 (pulp and plastic that did not dissolve in the cracked water) Capacity is low.

  After the supply of the decomposed water into the inner trunk separation tank 9 is stopped, the inner trunk separation tank 9 is rotated to dehydrate water remaining in the solid pulp and plastic. The decomposed water taken out from the pulp and plastic by this dehydration is discharged by the discharge unit 5. The solid matter after dehydration, that is, the pulp and plastic that are solid matter that has not been dissolved in the decomposed water remains in the inner cylinder separation tank 9.

Next, the processing procedure of the used paper diaper 2 by the processing apparatus 1 will be described.
As shown in FIG. 1, the used paper diaper 2 that has been weighed to a predetermined weight and made into one lump is carried to the front side 11 of the separator 4 by the charging machine 20.

  The separator 4 is tilted by turning the inlet / outlet door 14 counterclockwise in FIG. 4 around the lower corner 18 with the inlet / outlet 12 opened. In this state, the used paper diaper 2 that is weighed to a predetermined weight and made into one lump is fed into the inner trunk separation tank 9 from the loading / unloading port 12 of the separator 4 in this state. After the used paper diaper 2 is put into the inner trunk separation tank 9, the separator 4 is returned from the inclined state to the original position.

  Next, the inner trunk separation tank 9 is rotated at a predetermined rotational speed. In a state where the inner trunk separation tank 9 is rotated at a predetermined rotation speed, the supply water is supplied from the decomposition water supply port 30 into the inner trunk separation tank 9 by the supply pump 31. At the same time, the detergent is supplied into the inner trunk separation tank 9.

  When decomposition water is supplied into the inner body separation tank 9 while rotating the inner body separation tank 9, the used paper diaper 2 is swirled by the protrusion 9a, and the used paper diaper 2 on the lower side is also moved to the upper side. The decomposition water pours from the water and soaks the decomposition water. Thereby, pulp and plastic are separated from the used paper diaper 2. At the same time, the polymer polymer is decomposed by water and lime in the decomposed water, and filth (sewage) such as urine absorbed in the polymer polymer becomes moisture and comes out in the inner trunk separation tank 9.

  Therefore, the used paper diaper 2 is separated into pulp, urine and other filth (water), plastic, etc. dissolved in the decomposed water. While rotating the inner trunk separation tank 9 at a predetermined number of revolutions, a predetermined amount of decomposed water and detergent are introduced into the inner trunk separation tank 9, and after rotating the inner trunk separation tank 9 for a predetermined time, pulp, urine, etc. The decomposed water containing filth (moisture) is discharged from the discharge unit 5 to the outside. In the inner shell separation tank 9, pulp, plastic, and other materials that have not been dissolved in the decomposed water remain.

  The inner trunk separation tank 9 is rotated for a predetermined time in a state where a predetermined amount of cracked water is supplied into the inner trunk separation tank 9, and then the decomposed water is discharged from the discharge section 5, and the inner trunk separation tank 9 is kept for a certain period of time. Rotate. Thereby, the pulp and plastic which were not melt | dissolved in the decomposition water in the inner trunk separation tank 9 are dehydrated. The dehydrated water (decomposed water and sewage such as urine from the polymer) is discharged to the discharge unit 5. The decomposed water discharged to the discharge section 5 is stored in the drain pit 35 through the drain pipe 36, and the pulp is collected by the pulp collecting device 38.

  In addition, after discharging | emitting decomposition water from the discharge part 5, a predetermined amount of washing | cleaning water is injected | thrown-in to the inner trunk separation tank 9, the inner trunk separation tank 9 is rotated for a predetermined time, and the washing water in the inner trunk separation tank 9 is made after that. May be discharged to the discharge unit 5. That is, the used paper diaper 2 is separated into pulp and plastic, the polymer is decomposed with decomposition water, and then the pulp, plastic, and decomposed polymer in the inner trunk separation tank 9 are washed with washing water, that is, rinsed. May be. Even in this case, since the washing water used for rinsing contains pulp, it can be discharged to the discharge section 5 and recovered by the pulp recovery device 38.

  After the inner trunk separation tank 9 is rotated and dehydration is performed for a predetermined time, the separator 4 is rotated around the lower corner portion 16 with the inlet / outlet 12 of the separator 4 being opened. When the separator 4 is rotated around the lower corner portion 16, a mixture of dehydrated pulp and plastic in the inner trunk separation tank 9 is taken out on the conveyor 68. A mixture of pulp and plastic taken out on the conveyor 68 is transported and fed into the inner trunk sorting tank 55 from the slot 66 of the sorter 6.

  After the pulp and plastic are put into the inner trunk sorting tank 55, the inlet 66 is closed by the inlet door 67. In this state, the inner cylinder sorting tank 55 is rotated at a predetermined rotational speed, and high-temperature steam is introduced into the heater body 108 of the heater 103 to drive the fan 104. The outside air is heated by the heater 103 into the outer trunk sorting tank 54 and is introduced into the inner trunk sorting tank 55 through a hole on the outer peripheral surface of the inner trunk sorting tank 55 as a dry wind. Is done. As a result, the pulp and plastic slightly containing water after dehydration in the inner trunk sorting tank 55 are dried.

  The pulp dried in the inner trunk sorting tank 55 passes through a hole provided on the outer periphery of the inner trunk sorting tank 55, enters the outer trunk sorting tank 54, and is accumulated and stored in the pulp receiving tank 80. At the same time, the dry air sucked out by the fan 104 is sent to the pulp collecting device 112 through the duct 111 and is captured by the bag filter. As a result, the dried plastic remains in the inner trunk sorting tank 55.

  Then, the pulp accumulated (stored) in the pulp receiving tank 80 is discharged to the pulp take-out conveyor 85 and collected by opening the double door 82 and opening the bottom 81. Further, the pulp sucked out by the fan 104 from the inner body sorting tank 55 together with the drying air is collected by the pulp collecting device 112. Further, the dried plastic remaining in the inner cylinder sorting tank 55 is taken out from the take-out port 69.

  When taking out the dried plastic remaining in the inner trunk sorting tank 55 from the outlet 69, the casing 53 is tilted by the tilting device 61 and taken out from the inner trunk sorting tank 55.

  As described above, according to the present embodiment, the used paper diaper 2 is mixed with a plurality of kinds of materials (pulp, plastic, etc.) by mixing the decomposed water introduced by the separator 4 and the used paper diaper 2. ). At the same time, filth (sewage such as urine) in the used paper diaper 2 is separated and discharged together with the decomposed water by the discharge unit 5. In addition, the pulp and plastic separated by the separator 4 are dried by the sorter 6 to sort at least the pulp and plastic.

  As a result, used paper diapers can be separated into multiple types of materials (pulp, plastic, etc.) that make up paper diapers, and wastes absorbed by the polymer are also separated from the polymer and used. The paper diaper 2 can be sorted into at least pulp and plastic.

  Moreover, in the said embodiment, the pulp which is separated from the used paper diaper 2 by the separator 4 and recovered by the pulp recovery device 38, and the pulp which is selected by the separator 6 and accumulated in the pulp receiving tank 80 and recovered. The pulp contained in the dry air and recovered by the pulp recovery device 112 is recovered from the used paper diaper 2. Thereby, pulp can be efficiently recovered from the used paper diaper 2.

  Moreover, in the said embodiment, the finally dried plastic can be collect | recovered. Thereby, the collected plastic can be reused.

  In the above embodiment, when the decomposed water is immersed (penetrated) in the used paper diaper 2 in the inner trunk separation tank 9, it is poured (sprayed) from the upper part of the used paper diaper 2 in the inner trunk separation tank 9. Therefore, it becomes possible to shorten the separation time and the decomposition time of the used paper diaper in the inner trunk separation tank 9 as the used water diaper 2 soaks into the decomposed water quickly.

  That is, in the state where the cracked water is supplied into the inner trunk separation tank 9 in advance, the decomposed water is stored in the lower side of the inner trunk separation tank 9, so that the used paper diaper 2 is placed in the inner trunk separation tank 9 in this state. When thrown in, the used paper diaper put in by the decomposed water stored on the lower side of the inner trunk separation tank 9 is in a floating state. Thus, when the inner trunk separation tank 9 is rotated with the used paper diaper 2 floating in the decomposed water, there is a used paper diaper that is not soaked in the decomposed water, and it takes time to separate and disassemble the used paper diaper. Take it.

  On the other hand, the decomposition water quickly permeates into the used paper diaper 2 by being poured from the upper part of the used paper diaper in the inner body separation tank 9, that is, by the Niagara method, and separated and decomposed. Is promoted. In addition, since the used paper diaper 2 in the inner body separation tank 9 is swirled by the protrusion 9a, the used paper diaper 2 on the lower side also moves to the upper side, and the decomposed water pours from the upper side, so that the used paper diaper The whole of 2 quickly penetrates the decomposed water.

  Further, in the above embodiment, urine and other filth (sewage) that has come out in the inner trunk separation tank 9 due to decomposition of the polymer in the inner trunk separation tank 9 by lime in the decomposed water is used together with the decomposed water. Since the used paper diaper 2 is separated, there is no need to add a wasteful amount of decomposed water. In addition, since the filth (sewage) in the polymer contributes to the separation of the used paper diaper 2, it is not necessary to add an excessive amount of the decomposed water, and the discharged water is discharged together with the pulp dissolved in the decomposed water. Since it can be discharged in a short time even when it is discharged, the working time for separation and decomposition in the inner trunk separation tank 9 can be greatly shortened.

  That is, a certain amount of decomposed water is put into the inner trunk separation tank 9, and sewage such as urine from the polymer polymer by decomposing the used paper diaper with this decomposed water also contributes to the separation of the used paper diaper 2. Therefore, the amount of the decomposed water put into the inner trunk separation tank 9 can be reduced, and even when discharged to the discharge unit 5, it can be discharged in a short time. Thereby, it becomes possible to shorten the working time for separation and disassembly.

  Further, according to the above embodiment, the pulp take-out conveyor 85 for taking out the recovered pulp from the sorter 6 to the pulp receiving tank 80 is provided with the inclined portions 102 and 102 on both sides of the conveyor belt 92, thereby reducing the powder. The body-like pulp can be collected on the center side in the width direction of the conveyor belt 92.

  Moreover, according to the said embodiment, by providing the diffusion prevention pieces 93 and 93 in the guide side walls 96 and 96 of the pulp extraction conveyor 85, powdery pulp is prevented from scattering to the back surface side of the conveyor belt 92. can do.

  Further, in the pulp take-out conveyor 85 of the above-described embodiment, a groove 99 is provided in the intermediate portion in the axial direction of the drive roll, and the protrusion 100 provided in the intermediate portion in the width direction of the conveyor belt 92 is fitted into this groove 99. Thus, meandering of the conveyor belt 92 can be prevented.

  In the above embodiment, the detergent is supplied into the inner trunk separation tank 9 through a pipe line different from the decomposed water. However, the detergent may be supplied into the inner trunk separation tank 9 together with the decomposed water. In this case, the detergent cleans the pulp and plastic by rotating the inner trunk separation tank 9 together with urine and other filth (sewage) that is generated by decomposition of the polymer by lime in the decomposed water. And since it is finally collected by the discharge part 5 together with the decomposed water, it is not necessary to supply it from the upper part of the used paper diaper together with the decomposed water. It ’s fine.

  Moreover, although the said embodiment demonstrated the example which processes a used paper diaper as a sanitary article, if the said processing apparatus 1 is a sanitary article which absorbs water | moisture content by polymer polymers, such as a urine leak pad and a sanitary napkin, it is. Pulp, plastic and filth (sewage) can be separated, decomposed and recovered.

  Although the embodiments of the present invention have been disclosed as described above, it is obvious that those skilled in the art can make changes without departing from the scope of the present invention. All such modifications and equivalents are intended to be included in the following claims.

  The used paper diaper processing apparatus according to the present invention, in addition to processing used paper diapers, is used for processing sanitary goods that absorb filth such as urine with a polymer, such as sanitary napkins, urine leak pads, etc. Also available.
