도 1 및 도 2를 참조하면, 폐스티로폼 축소기(100)는 본체(110)와, 본체(110)에 설치된 파쇄기(120), 실린더(140), 나선형 이송스크류(150), 분쇄가이드편(161) 및 히터(180)를 구비한다.1 and 2, the waste styrofoam reducer 100 includes a main body 110, a crusher 120 installed on the main body 110, a cylinder 140, a spiral feed screw 150, and a grinding guide piece ( 161 and a heater 180.
파쇄기(120)는 본체(110) 상부에 형성된 투입구(112)를 통해 유입된 폐스티로폼을 파쇄할 수 있는 복수개의 파쇄롤러(121)(123)(125)가 적용되었다.The crusher 120 has been applied to a plurality of shredding rollers 121, 123, 125 that can shred waste styrofoam introduced through the inlet 112 formed on the main body 110.
제1파쇄롤러(121)는 제1회전축(121a)과, 제1회전축(121a)에 상호 이격되게 형성된 다수개의 절단날(121b)을 갖는 구조가 적용되었다.The first shredding roller 121 has a structure having a first rotating shaft 121a and a plurality of cutting blades 121b formed to be spaced apart from each other on the first rotating shaft 121a.
제2파쇄롤러(123)는 제1파쇄롤러(121)를 거쳐 1차 파쇄된 폐스티로폼을 2차로 파쇄할 수 있도록 제2회전축(123a)에 다수의 절단날(123b)이 상호 이격되게 형성된 구조가 적용되었다.The second shredding roller 123 has a structure in which a plurality of cutting blades 123b are spaced apart from each other on the second rotating shaft 123a so that the first shredded styrofoam can be secondly shredded through the first shredding roller 121. Was applied.
제3파쇄롤러(125)는 제3회전축(125a)에 다수의 절단날(125b)이 상호 이격되게 설치되되 제2파쇄롤러(123)의 절단날 사이에 배열되게 설치된 구조가 적용되었다. The third shredding roller 125 has a structure in which a plurality of cutting blades 125b are installed on the third rotary shaft 125a so as to be spaced apart from each other, and arranged between the cutting blades of the second shredding roller 123.
제2파쇄롤러(123)와 제3파쇄롤러(125)는 그 회전중심이 수직상에서 상호 어긋나게 배치된다.The second crushing roller 123 and the third crushing roller 125 are disposed so that their rotation centers are shifted from each other on the vertical.
이러한 제2 및 제3파쇄롤러(123)(125)는 상호 반대방향으로 회전되게 구동시켜 제1파쇄롤러(121)를 거쳐 인입되는 폐스티로폼을 2차 분쇄함과 아울러 하부의 실린더(140) 유입구(141)로 이송시킨다.The second and third shredding rollers 123 and 125 are driven to rotate in opposite directions to secondly grind the waste styrofoam introduced through the first shredding roller 121, as well as the inlet of the lower cylinder 140. Transfer to (141).
각 파쇄롤러(121)(123)(125)의 절단날(121b)(123b)(125b)은 도시된 예와 다르게 배치되거나 적용되는 개수를 달리 적용할 수 있음은 물론이다.Cutting blades 121b, 123b, 125b of each of the shredding rollers 121, 123, 125 may be applied differently to the number that is arranged or applied differently from the illustrated example.
각 파쇄롤러(121)(123)(125)의 동력전달구조는 후술한다.The power transmission structure of each of the shredding rollers 121, 123, 125 will be described later.
폐스티로폼을 파쇄하는 파쇄기(120)의 구조는 도시된 구조와 다른 공지된 구조가 적용될 수 있음은 물론이다.The structure of the crusher 120 to crush the waste styrofoam can be applied to other well-known structures other than the structure shown.
실린더(140)는 중공을 갖는 구조이며, 제2 및 제3파쇄롤러(123)(125)를 거친 폐스티로폼을 유입받을 수 있게 유입구(141)가 형성되어 있고, 본체의 배출구(115)까지 연장되게 형성되어 있다.Cylinder 140 has a hollow structure, the inlet 141 is formed to receive the waste styrofoam passed through the second and third shredding rollers 123, 125, and extends to the outlet 115 of the body It is formed.
실린더(140) 내에는 나선형 이송스크류(150)가 회전가능하게 설치되어 있다.The spiral feed screw 150 is rotatably installed in the cylinder 140.
또한 실린더(140) 내벽에는 분쇄가이드편(161)이 복수개 설치되어 있다.In addition, a plurality of grinding guide pieces 161 are provided on the inner wall of the cylinder 140.
도시된 예에서는 분쇄가이드편(161)이 실린더(140)의 내벽에 90도 간격으로 4개가 중심부분을 향해 돌출되어 길이방향을 따라 일정길이 연장되게 형성되어있다. 도시된 예와 다르게 분쇄가이드편(161)의 적용수를 달리 적용할 수 있음은 물론이다.In the illustrated example, four grinding guide pieces 161 are formed on the inner wall of the cylinder 140 at 90 degree intervals so as to protrude toward the central portion and extend a predetermined length along the longitudinal direction. Unlike the illustrated example, the number of applications of the grinding guide piece 161 may be applied differently.
또한, 분쇄가이드편(161)은 실린더(140)의 내벽으로부터 나선형 이송스크류(150)에 간섭되지 않을 정도로 중심부를 향해 돌출되되 돌출부분이 사각형 형상으로 각이지게 형성되어 있다.In addition, the grinding guide piece 161 is protruded toward the center so as not to interfere with the helical feed screw 150 from the inner wall of the cylinder 140, the protrusion is formed in an angle in a rectangular shape.
분쇄 가이드편(161)의 연장방향은 나선형 이송스크류(150)의 제4회전축(151)으로부터 나선형으로 확장되게 형성된 나선형 날개(152)의 궤적에 대해 일정각도 어긋나게 형성되면 되고 도시된 예에서는 나선형 이송스크류(150)의 길이방향을 따라 연장되어 있다.The extending direction of the grinding guide piece 161 may be formed to be shifted at a predetermined angle with respect to the trajectory of the spiral blade 152 formed to extend spirally from the fourth rotating shaft 151 of the spiral conveying screw 150. It extends along the longitudinal direction of the screw 150.
이러한 구조에서 파쇄기(120)를 거쳐 실린더(140) 내로 진입된 폐스티로폼이 나선형 이송스크류(150)의 회전에 의해 나선형 날개(152)의 궤적을 따라 이송될 때 이송궤적과 일정 각도 어긋나게 설치된 분쇄가이드편(161)이 폐스티로폼을 3차로 절단하는 절단기로서 작용하기 때문에 폐스티로폼을 보다 미세하게 파쇄시킬 수 있다. In this structure, when the waste styrofoam entered into the cylinder 140 through the crusher 120 is transported along the trajectory of the spiral blade 152 by the rotation of the helical conveying screw 150, a grinding guide installed at a predetermined angle is shifted from the conveying trajectory. Since the piece 161 acts as a cutter for cutting the waste styrofoam in three steps, the waste styrofoam can be more finely crushed.
분쇄가이드편(161)은 실린더(140) 부분 중 히터(180) 장착부분 이전 까지 형성되는 것이 바람직하다.The grinding guide piece 161 is preferably formed before the heater 180 mounting portion of the cylinder 140.
히터(180)는 실린더(140) 내를 이송하는 폐스티로폼에 열을 인가하여 용융시킬 수 있도록 분쇄가이드편(161)의 종단 이후의 실린더(180)의 중앙부분에 설치되어 있다.The heater 180 is installed at the central portion of the cylinder 180 after the end of the grinding guide piece 161 so as to apply heat to the waste styrofoam conveying the cylinder 140 to melt.
송풍기(190)는 실린더(140) 내를 이송하면서 파쇄 및 융용되는 폐스티로폼으로부터 발생되는 가스를 배출할 수 있도록 실린더(140)에 형성된 관통공(143) 외측에 설치되어 있다.The blower 190 is installed outside the through hole 143 formed in the cylinder 140 so as to discharge the gas generated from the waste styrofoam being broken and melted while being transported in the cylinder 140.
제2 및 제3 파쇄롤러(123)(125)는 상호 반대방향으로 회전되도록 하면서, 제1파쇄롤러(121) 및 나선형 이송스크류(150)를 구동원에 의해 구동시킬 수 있도록 동력전달구조가 적용되면 되고, 도시된 예에서는 제1모터(131)가 제1 및 제2파쇄롤러(121)(123)를 벨트에 의해 연동되게 회전시킬 수 있도록 되어 있고, 제2모터(133)가 나선형 이송 스크류(150) 및 제3파쇄롤러(125)를 벨트에 의해 연동되게 회전시킬 수 있도록 되어 있다.When the second and third shredding rollers 123 and 125 are rotated in opposite directions, the power transmission structure is applied to drive the first shredding roller 121 and the helical feed screw 150 by a drive source. In the illustrated example, the first motor 131 may rotate the first and second shredding rollers 121 and 123 to be interlocked by a belt, and the second motor 133 may be a helical feed screw. 150 and the third shredding roller 125 can be rotated to be interlocked by the belt.
즉, 제1모터(131)의 회전축에 설치된 제1구동풀리(131c)와 제2파쇄롤러(123)의 제2회전축(123a)에 설치된 제1종동풀리(123c)가 벨트에 의해 연결되어 있고, 제2파쇄롤러(123)의 제2종동풀리(123d)가 제1파쇄롤러(121)의 제3종동풀리(121c)와 벨트에 의겨 연결되어 있다.That is, the first driven pulley 131c installed on the rotation shaft of the first motor 131 and the first driven pulley 123c installed on the second rotation shaft 123a of the second shredding roller 123 are connected by a belt. The second driven pulley 123d of the second shredding roller 123 is connected to the third driven pulley 121c of the first shredding roller 121 by the belt.
또한, 제2모터(133)의 회전축에 설치된 제2구동풀리(133c)와 제3구동풀리(133d)는 각각 제3파쇄롤러(125)의 제3회전축(125a)에 설치된 제4종동풀리(125c)와, 나선형 이송스크류(150)의 제4회전축(151)에 설치된 제5종동풀리(151c)와 각각 벨트에 의해 연결되어 있다.In addition, the second driving pulley 133c and the third driving pulley 133d installed on the rotation shaft of the second motor 133 are respectively driven by the fourth driven pulley (3) installed on the third rotation shaft 125a of the third shredding roller 125. 125c and the fifth driven pulley 151c provided on the fourth rotating shaft 151 of the helical feed screw 150, respectively, by belts.
나선형 이송스크류(150), 제1파쇄롤러(121), 제2파쇄롤러(123) 및 제3파쇄롤러(125)를 구동하기 위한 구동원으로서 도시된 예에서는 2개의 모터(131)(133)가 적용되었으나, 도시된 예와 다르게 하나의 모터를 이용하여 원하는 방향으로 각 회전축이 회전될 수 있게 동력중계수단을 적용하거나 독립적으로 모터를 설치하는 방법 등 각 회전축의 구동방식은 다양하게 적용될 수 있음은 물론이다.In the example shown as a driving source for driving the spiral feed screw 150, the first shredding roller 121, the second shredding roller 123, and the third shredding roller 125, two motors 131 and 133 are However, unlike the illustrated example, a driving method of each rotating shaft may be variously applied, such as applying a power relay means or installing a motor independently so that each rotating shaft can be rotated in a desired direction using a single motor. Of course.
이러한 구조의 폐스티로폼 축소기(100)는 파쇄기(120)를 거쳐 실린더(140) 내로 일정크기 이하로 절단된 폐스티로폼이 나선형 이송스크류(150)에 의해 실린더(140) 내에서 이송되는 과정에서 분쇄가이드편(161)에 의해 보다 미세하게 분쇄되어 이후의 히터(180)에 의한 용융효율을 높여 폐스티로폼의 축소효율을 높일 수 있다.The waste styrofoam reducer 100 having such a structure is crushed in a process in which waste styrofoam cut to a predetermined size or less into the cylinder 140 through the crusher 120 is transferred in the cylinder 140 by the spiral feed screw 150. More finely pulverized by the guide piece 161 to increase the melting efficiency of the heater 180 afterwards to increase the reduction efficiency of the waste styrofoam.
지금까지 설명된 바와 같이 본 발명에 따른 폐스티로폼 축소기에 의하면 폐스티로폼의 축소 효율을 보다 높일 수 있는 장점을 제공한다.As described so far, the waste styrofoam reducer according to the present invention provides an advantage of further increasing the reduction efficiency of the waste styrofoam.
