상기 탈수장치에서 1차 탈수된 쓰레기는 배출구(18a)를 통해 빠져나와 다음 단계인 이물질 선별장치(20)에 투입된다.The first dewatered waste from the dewatering device is discharged through the discharge port 18a and then put into the foreign matter sorting device 20.
선별장치에 투입되면 쓰레기에 포함된 젓가락 등의 이물질은 상단 투입망(21a)에 걸리게 되고, 걸린 이물질은 분리스크류(22)의 회전에 의해 외부로 분리되고 순수 쓰레기만이 몸체(21) 내로 수용된다.When put into the sorting device, foreign matters such as chopsticks included in the waste are caught in the upper input network 21a, and the caught foreign matter is separated to the outside by the rotation of the separating screw 22, and only pure waste is received into the body 21. do.
이 때 상기 몸체는 바이브레이터(23)에 의해 진동되어 투과망에 장애를 받지않게 된다.At this time, the body is vibrated by the vibrator 23 is not disturbed by the transmission network.
이물질이 분리된 쓰레기는 다음 단계인 분쇄장치(30)에 투입되어 분쇄기(31)에 의해 분쇄되고, 이어서 본 발명의 핵심장치인 건조장치(40)에 투입된다.Garbage from which foreign matters are separated is put into a crusher 30 which is the next step, pulverized by the crusher 31, and then put into a drying apparatus 40 which is the core apparatus of the present invention.
즉, 건조장치의 투입호퍼(42)에 투입되면 이송스크류(42a)에 의해 이송되어 1차건조드럼(45)을 통과하게 된다.That is, when it is put into the input hopper 42 of the drying apparatus is transferred by the transfer screw 42a is passed through the primary drying drum (45).
이 때 건조실(41) 내에는 보일러(50)에서 발생된 열기가 이미 공급되어 있는 상태이고 그 열기는 상기 1차건조드럼(45)을 가열하고 있는 상태이다.At this time, the heat generated from the boiler 50 is already supplied into the drying chamber 41, and the heat is heating the primary drying drum 45.
따라서 모터(45c)에 의해 회전하는 1차건조드럼(45)은 데워지게 됨과 함께 1차건조드럼에 형성된 절개홈(45a)을 통해 열기가 발산되어 압송되는 쓰레기를 1차적으로 건조시키게 된다.Therefore, the primary drying drum 45 which is rotated by the motor 45c is warmed and heat is diverted through the incision groove 45a formed in the primary drying drum to dry the garbage transported primarily.
1차건조드럼 상의 쓰레기는 1차건조드럼의 외주면에 형성된 이송스크류홈(45b)의 작용으로 전진 이동이 가능하다.Garbage on the primary dry drum can be moved forward by the action of the transfer screw groove 45b formed on the outer circumferential surface of the primary dry drum.
1차건조드럼을 통과하면서 1차건조된 쓰레기는 다음 단계인 2차건조드럼(49)에 투입된다.The first dry waste is passed to the second dry drum 49 while passing through the first dry drum.
즉, 2차건조드럼의 직경이 작은 입구에 투입된 쓰레기는 모터(48)에 의해 회전하는 교반축(46) 및 교반봉(47)에 의해 교반되면서 큰 직경 방향으로 이동된다.That is, the waste put into the inlet of the small diameter of the secondary drying drum is moved in the large diameter direction while being stirred by the stirring shaft 46 and the stirring rod 47 rotated by the motor 48.
이 때 상기 교반축(46)은 고속회전되고, 교반봉(47)은 저속회전되도록 함이 바람직하다.At this time, the stirring shaft 46 is rotated at high speed, it is preferable that the stirring rod 47 is rotated at low speed.
상기 교반작용은 교반봉(47)과 교반축의 교반날개(46b)의 작용에 의해 가능하게 되고, 전진 이동은 반추형의 드럼 형상으로 형성된 경사면에 의해 가능하다.The stirring action is enabled by the action of the stirring rod 47 and the stirring blade 46b of the stirring shaft, and the forward movement is possible by the inclined surface formed in the ruminant drum shape.
상기 교반작용 과정에서는 브로워(52)에서 발생된 공기가 교반축(46)으로 공급되어 상기 교반축에 형성된 다수의 통공(46a)을 통해 분사공급됨으로써 건조되는 쓰레기에서 발생되는 수분이 수증기화되어 기화소멸되는 까달겡 매우 효율적인 건조작용이 수행된다.In the stirring process, air generated in the brow 52 is supplied to the stirring shaft 46 and sprayed through a plurality of through holes 46a formed in the stirring shaft to vaporize moisture generated in the dried garbage. A very efficient drying is carried out.
즉, 상기 2차건조드럼(49) 역시 건조실 내의 열기에 의해 데워진 상태이기 때문에 교반이동하는 과정에서 쓰레기는 효율적으로 건조되고, 더욱이 교반축(46)에 형성된 다수의 통공(46a)에서는 브로워(52)에서 발생된 공기가 공급되어져 보다 효율적인 건조가 행해진다.That is, since the secondary drying drum 49 is also warmed by the heat in the drying chamber, the waste is efficiently dried during the stirring movement, and moreover, in the plurality of through holes 46a formed in the stirring shaft 46, the blower 52 The air generated in) is supplied, and more efficient drying is performed.
이러한 건조작용은 그 하방으로 병렬 설치된 동일한 2차건조드럼(49)들을 순차적으로 통과하면서 수분이 완전히 제거되는 완벽한 건조작용이 행해진다.This drying action is carried out in a perfect drying action in which water is completely removed while sequentially passing through the same secondary drying drums 49 installed in parallel thereunder.
이 과정에서 발생된 건조실 내의 열기 및 수증기는 집진기(53)를 통해 외부로 배출된다.Heat and steam in the drying chamber generated in this process is discharged to the outside through the dust collector (53).
상기 건조실 내에 열기를 공급하는 보일러(50)의 연료로는 폐타이어 등의 연료가 사용될 수 있고, 발생되는 열기는 브로워(50a)에 의해 반 강제적으로 건조실 내로 공급한다.As a fuel of the boiler 50 for supplying heat into the drying chamber, fuel such as waste tires may be used, and the generated heat is semi-forcedly supplied into the drying chamber by the blower 50a.
최하단에 설치된 최종 2차건조드럼(49)를 통과한 건조된 슬러지 또는 음식물 쓰레기는 건조실의 하단에 형성된 토출구(41a)를 통해 빠져나와 포장단계를 거치게 된다.The dried sludge or food waste that has passed through the final secondary drying drum 49 installed at the bottom end is discharged through the discharge port 41a formed at the bottom of the drying chamber and undergoes a packing step.
이상에서 설명한 바와 같이 본 발명의 슬러지 및 음식물쓰레기 건조장치는,수거된 쓰레기에 함유된 수분을 가압방식에 의해 1차적으로 제거시키는 탈수장치와, 탈수된 쓰레기에 포함된 젓가락 등의 이물질을 제거하는 선별장치와, 선별된 쓰레기를 분쇄시키는 분쇄장치, 및 가열방식에 의해 최종 건조시키는 건조장치를 포함하는 구성에 의해, 쓰레기에 함유된 수분이 거의 완벽할 정도로 효율적으로 처리되는 효과를 발휘한다.As described above, the sludge and food waste drying apparatus of the present invention includes a dehydration apparatus that primarily removes moisture contained in the collected waste by a pressurized method, and removes foreign substances such as chopsticks contained in the dehydrated waste. The configuration including a sorting apparatus, a pulverizing apparatus for pulverizing the sorted waste, and a drying apparatus for final drying by a heating method exerts an effect that the moisture contained in the waste is efficiently processed almost completely.
이상의 본 발명은 기재된 실시예에만 한정되는 것이 아니고 본 발명의 요지를 벗어나지 않는 범위내에서 당업자에 의해 본 발명을 다양하게 변경하여 실시할 수 있음은 자명하므로 이와 같이 변경된 실시예들은 첨부의 특허청구범위에 속한다 해야 할 것이다.The present invention is not limited to the embodiments described above, it will be apparent to those skilled in the art that various changes can be made by those skilled in the art without departing from the gist of the present invention, the embodiments so modified are the appended claims You will have to belong to.
