Description

슬러지 발효 감량장치Sludge Fermentation Reduction Device
본 발명은 슬러지 감량장치에 관한 것으로, 특히 슬러지가 발효를 통해 감량되도록, 슬러지와 미생물을 지속적으로 교반시키는 슬러지 발효 감량장치와 관련된다.The present invention relates to a sludge reduction device, and more particularly, to a sludge fermentation reduction device for continuously stirring the sludge and microorganisms so that the sludge is reduced through fermentation.
일반적으로 식품 공장, 축산 농가, 하수처리장 등에서 발생되는 슬러지(음식물 쓰레기, 분뇨, 폐수 등)는 다량의 수분을 함유한 다습성 물질이다. In general, sludge (food waste, manure, waste water, etc.) generated in food factories, livestock farms, sewage treatment plants, etc. is a humid material containing a large amount of moisture.
이러한 슬러지를 아무런 처리 없이 바로 매립하게 되면, 토양과 지하수가 슬러지에서 생성되는 대량의 침출수로 인해 오염될 수 있다. 또한, 매립지 인근에 심한 악취가 발생할 수 있다.If the sludge is landfilled without any treatment, the soil and groundwater can be contaminated by the large amount of leachate produced by the sludge. In addition, severe odors may occur near landfills.
전술한 사유로, 종래에는 매립 전에 슬러지를 미생물과 교반하여 발효시킴으로써, 슬러지에 함유된 수분을 제거하고, 부피와 중량을 감소시키는 슬러지 발효 감량처리가 선행되었다. 발효 감량된 슬러지는 수분과 악취가 현저하게 제거되어 연료나 비료 등으로 재활용되기도 한다.For the above reasons, conventionally, sludge fermentation and weight loss treatment for removing water contained in sludge and reducing volume and weight has been preceded by stirring and fermenting sludge with microorganisms before landfilling. Reduced fermentation of sludge can be recycled as fuel or fertilizer due to the significant removal of moisture and odor.

The air injected into the hollow 122 of the pipe shaft 120 is discharged through the air discharge hole 124 described above. Since the present invention can easily supply air to only the air discharge hole 124 simply formed in the pipe shaft 120, there is no need to provide a separate air supply pipe inside the fermentation tank 110. For this reason, the present invention has an effect that can significantly reduce the manufacturing cost of the device. In addition, the air discharge hole 124 is provided between the blades of the transfer screw 130. Through this, the present invention can perform the stirring function and the air supply function in the same space at the same time, it is possible to greatly improve the activity of the microorganism.
모터(170)는 발효조(110)의 외부에 배치된다. 모터(170)는 발효조(110)의 하부에 노출된 파이프 샤프트(120)와 구동벨트로 연결되어, 파이프 샤프트(120)에 회전력을 전달하는 기능을 수행한다.The motor 170 is disposed outside the fermenter 110. The motor 170 is connected to the pipe shaft 120 and the driving belt exposed at the lower portion of the fermentation tank 110, and performs a function of transmitting a rotational force to the pipe shaft 120.
교반날개(150)는 파이프 샤프트(120)의 타측(하측)에 결합되어, 파이프 샤프트(120)가 회전될 때, 일체로 회전된다. 교반날개(150)는 발효조(110) 내의 슬러지가 이송관(140)을 중심으로 소용돌이치며 교반되게 하여, 효과적인 발효가 이루어지도록 한다. 특히, 발효조(110)의 내벽에서 점착되거나 자체적으로 응고될 수 있는 슬러지를 지속적으로 분해 및 유동시켜, 슬러지의 교반흐름이 적체되는 것을 방지한다.The stirring blade 150 is coupled to the other side (lower side) of the pipe shaft 120, when the pipe shaft 120 is rotated, integrally rotated. The stirring blade 150 allows the sludge in the fermentation tank 110 is swirled and stirred about the transfer pipe 140, so that the effective fermentation is made. In particular, the sludge that can stick or solidify itself on the inner wall of the fermentation tank 110 is continuously decomposed and flowed, thereby preventing the agitation flow of the sludge from accumulating.
도 2 내지 도 3을 참조하면, 교반날개(150)의 단부는 발효조(110)의 하부 형상에 대응되게 절곡 형성될 수 있다. 절곡 형성된 교반날개(150)의 단부는 발효조(110)의 하부 경사면에 점착되는 슬러지를 긁어내는 스크레이퍼(scraper) 기능을 수행한다. 이를 통해, 발효조(110)의 하부 경사면에 슬러지가 점착되어 슬러지의 교반흐림이 적체되는 것을 방지한다. 또한, 교반날개(150)는 파이프 샤프트(120)에 복수개가 교차로 적층되게 구비되는 것이 바람직하다. 특히, 2개의 교반날개(150)가 '十'자로 적층 형성될 경우, 교반기능과 스크레이퍼기능을 극대화 시킬 수 있다. 한편, 교반날개(150)의 외측면 소정 위치, 즉 칼날 부위에는 공기노즐부(154)가 구비된다. 교반날개(150)의 내부에는 빈공간(152)이 형성되는데, 빈공은(152)은 파이프 샤프트(120)의 공기배출홀(124)과 연통된다. 공기배출홀(124)로 배출되는 공기는 빈공간(152)을 통과하여 공기노즐부(154)로 방출된다. 교반날개(150)에 공기노즐부(154)가 형성되면, 이송관(140)의 외부 영역에도 공기를 공급할 수 있는 효과가 발생한다.2 to 3, the end of the stirring blade 150 may be bent to correspond to the lower shape of the fermentation tank 110. The end of the bent stirring blade 150 performs a scraper function to scrape the sludge adhered to the lower inclined surface of the fermentation tank (110). Through this, the sludge is adhered to the lower inclined surface of the fermentation tank 110 to prevent the agitation of the sludge accumulated. In addition, the stirring blade 150 is preferably provided so that a plurality of stacks are laminated on the pipe shaft 120. In particular, when the two stirring blades 150 are formed to be stacked with '十', the stirring function and the scraper function can be maximized. On the other hand, the air nozzle unit 154 is provided at a predetermined position of the outer surface of the stirring blade 150, that is, the blade portion. An empty space 152 is formed inside the stirring blade 150, and the empty hole 152 is in communication with the air discharge hole 124 of the pipe shaft 120. The air discharged to the air discharge hole 124 passes through the empty space 152 and is discharged to the air nozzle unit 154. When the air nozzle unit 154 is formed on the stirring blade 150, an effect of supplying air to the outer region of the transfer pipe 140 occurs.
마지막으로, 발효조(110)의 내벽에는 버티칼 스크류(180)가 내주를 따라 등 간격 이격되게 구비된다. 버티칼 스크류(180)는 파이프 샤프트(120) 보다 천천히 회전하며, 이송스크류(130), 교반날개(150)와 조합되어, 발효조(110) 내부에서 슬러지가 입체적으로 유동될 수 있도록 한다. 이를 통해, 슬러지와 미생물이 교반이 보다 효과적으로 이루어진다. 또한, 버티칼 스크류(180)는 발효조(110)의 상부 벽면에 슬러지가 점착되는 것을 방지하는 기능을 한다.Finally, the vertical screw 180 is provided on the inner wall of the fermenter 110 to be spaced apart along the inner circumference. The vertical screw 180 rotates more slowly than the pipe shaft 120, and is combined with the transfer screw 130 and the stirring blade 150 to allow the sludge to flow in the fermenter 110 in three dimensions. Through this, the sludge and microorganisms are more effectively stirred. In addition, the vertical screw 180 serves to prevent the sludge adhered to the upper wall surface of the fermentation tank (110).
