In the figure, reference numeral 58 is a supply water line for supplying cleaning water to the water supply tank 53 from a water supply connection port 59 provided on the outer wall of the apparatus body 1, and reference numeral 60 is an overflow pipe.

Next, an operation when the fibrous waste such as a disposable diaper is processed by the waste processing apparatus having the above configuration will be described.
First, when a fibrous waste such as a paper diaper is supplied into the input unit 2 from the input port 2a of the apparatus main body 1, the waste is sent into the hopper 8 by the roller conveyor 7, and the lower part is opened from the opening 8a. It falls to the shredder 3.

  In the shredder 3, the shredder 3 is finely pulverized by the rotary blade 10 rotated by the motor 11. At this time, the motor 11 is rotated in the reverse direction every predetermined time (for example, every 2 to 3 seconds). Then, in FIG. 6, when the crushing blades 10a located above the respective rotation shafts 9 rotate in the approaching direction, the waste at the top is bitten downward from both sides by the crushing blades 10a. It is cut surely. As a result, for example, not only a polymer absorbent that is a main component of a paper diaper, but also ultrafine rubber and the like that are contained in a large amount in this type of paper diaper can be cut into fine pieces.

  Next, when the motor 11 rotates in the reverse direction, the biting is once released, so that the shredder 3 can be prevented from being clogged with the waste. At the same time, the cutting water from the water supply tank 53 is sprayed from the upper side of the shredder 3 through the water supply pump 54 and the header 55, so that the cutting and pulverization can be performed smoothly and the rotation. It is also possible to prevent the odor from being generated by sticking the polymer absorbent to the blade 10.

  Next, the waste finely cut in the shredder 3 falls from between the rotary blades 10 into the stirring tank 4 below. On the other hand, in the tank body of the agitation tank 4, the cleaning water in the water supply tank 53 is supplied from the jet outlet 57 via the water supply pump 54 and the header 56. In addition, for example, an additive such as calcium chloride for separating and dehydrating the polymer absorbent and a bactericide such as benizelconium chloride are injected from a supply line (not shown).

  In the agitation tank 4, the finely cut waste is agitated with the washing water or the like by the agitation blade 13 that is rotationally driven by the motor 15b and the speed reduction unit 15a, thereby effectively attaching the waste. The filth that has been removed is washed and sterilized, and the moisture and filth that have been absorbed by the polymer absorbent are dehydrated. At this time, since the auxiliary stirring plate 14 is provided on the inner wall of the side plate 4a of the tank main body, a vortex water flow can be generated in the tank main body with the stirring by the stirring blade 13, and therefore, efficiently, The washing, sterilization and dehydration can be performed.

  Next, the waste that has been cleaned, sterilized, and dehydrated in the stirring tank 4 is sent from the discharge pipe 19 to the subsequent compressor 5 together with the cleaning liquid and the like. At this time, a discharge portion 16 projecting outward and downward from the outer peripheral portion of the agitation tank 4 is provided, and a discharge port 17 is formed in the bottom plate 16a of the discharge portion 16; A swirling flow can be given to the washing water containing a large amount of waste that flows to the pipe 19 and smoothly conveyed to the subsequent compressor 5.

  In this way, the washing water and the waste material supplied into the compressor 5 from the supply port 20 through the discharge pipe 19 are discharged into the main body 22 as the screw 23 driven by the motor 28 rotates. It is sent to 21 side. Then, foreign substances such as cleaning water and SS smaller than the holes of the filter 24 pass through the filter 24 and flow to the discharge unit 25.

  On the other hand, the waste that does not pass through the filter 24 is sent through the main body 22 and sent from the discharge port 21 to the discharge pipe 26 through the short pipe 30. Then, since the discharge pipe 26 is an elbow pipe bent at 90 °, the waste W is subjected to conveyance resistance in the discharge pipe 26 and is compressed by the waste W sent later. At this time, the water squeezed out by compressing the waste W is discharged from the drain hole 31 of the short tube 30. Then, the sufficiently compressed waste W becomes a lump and is discharged to the outside from the distal end portion of the discharge pipe 26.

  Also, the cleaning liquid containing fine foreign matters such as underwater suspended matter (SS) that has flowed to the discharge unit 25 through the filter 24 is sucked by the drainage pump 35 and passed through the drainage line 33 from the discharge port 32 and the SS collector. 6 is sent. In parallel with this, a part of the flow is sent from the three-way flow control valve 51 to the return line 52 and returned to the stirring tank 4 again.

  The cleaning liquid containing SS and the like sent from the drain line 33 to the SS collector 6 flows into the main body 38 from the supply port 36, and further passes through the main body 38 by the rotation of the screw 39 driven by the motor 44. It is sent to the discharge port 37 side. In this process, water such as a cleaning liquid flows through the filter 40 to the discharge unit 41. In this way, the water such as the cleaning liquid from which foreign matters such as SS are removed by the filter 40 to the discharge standard or less is drained from the discharge port 50 of the drainage part 41 to the outside.

  On the other hand, the foreign matter P such as SS collected by the filter 40 is sequentially sent from the discharge port 37 to the discharge pipe 42 through the short pipe 46 by the screw 39. Then, since the discharge pipe 42 is formed in a taper shape whose inner diameter gradually decreases toward the tip side, the foreign matter P is subjected to conveyance resistance in the discharge pipe 42 and is caused by the foreign matter P sent later. Compressed. The squeezed moisture is discharged from the drain hole 47 of the short tube 46 to the discharge part 41 in the process of compressing the foreign matter P into a lump. Further, the foreign matter P is sufficiently compressed into a lump, and then discharged from the tip of the elbow pipe 48 to the outside.

  Thus, according to the waste processing apparatus having the above-described configuration, waste such as paper diapers is finely cut by the shredder 3, and then the waste cut in the stirring tank 4 is washed with a cleaning liquid, a disinfectant, and a polymer separating agent. After mixing, sterilizing and dewatering the waste, the waste is squeezed and dehydrated by the compressor 5, and the cleaning liquid separated by the compressor 5 is sent to the SS collector 6, Since the compressor 5 captures and discharges foreign matters such as SS that could not be collected, the waste from which the filth has been removed can be easily taken out as a compressed lump.

  For this reason, since the lump of waste can be processed easily and small foreign matters such as SS contained in the cleaning liquid can be removed in the SS recovery unit 6, it is possible to efficiently remove a disposable diaper or the like. Wastes composed of contaminated fibers and polymer absorbents can be washed and disposed of, and the SS and the like can also be removed from the wastewater to satisfy wastewater standards.

  In particular, since a part of the cleaning liquid or the like that has been separated by the compressor 5 and still contains foreign matters such as SS is circulated to the stirring tank 4 again, the efficiency of collecting waste and foreign matters in the compressor 5 is improved. Therefore, the load on the SS collector 6 in the subsequent stage can be reduced. Furthermore, in the compressor 5, since the main body 22 is inclined in a range of 55 ° to 65 ° with respect to the horizontal, water such as a cleaning liquid is efficiently separated through the filter 24 using gravity. Can do.

  Further, in the SS collector 6, in addition to the supply of high-pressure and high-volume cleaning liquid from the drain pump 35, the hole of the filter 40 is formed with a small diameter. Since it is wound, it is possible to ensure a large total opening area in the filter 40, thereby reducing the water pressure and preventing foreign matters such as SS from passing through the filter 40 excessively.

  Further, in the compressor 5 and the SS recovery unit 6, the filters 24 and 40 are tightly wound around the outer periphery of the screws 23 and 39, so that the waste adhered to the filters 24 and 40 during transportation Foreign matters such as SS can be peeled off by the screws 23 and 39, and the clogging of the filters 24 and 40 can be prevented at the same time.

Incidentally, milling means, as the stirring means, compressing means and debris collecting means, the shredder 3 configured as described above, stirred tank 4, the other compressor 5 and SS recovery unit 6, it can be applied to any of various structures It is.
