본 고안은 주물공장에서 주물공정후에 배출되는 폐주물사를 재활용하기 위한 폐주물사 재활용 선별기에 관한 것으로 좀더 상세하게는 폐주물사를 홉퍼에 투입하면 1차 금속과 주물사가 분리되어 콘베어벨트로 이송되고 2차 크기에 따라 대략 3종으로 분리되고 잔여된 것은 분쇄하여 최초과정으로 복귀하는 과정을 반복시켜 줌으로서 폐주물사를 효과적으로 재활용할 수 있게 한 것이다.The present invention relates to a waste foundry sand recycling sorter for recycling the waste foundry sand discharged from the foundry after the casting process. More specifically, when the waste foundry sand is put into a hopper, the primary metal and the foundry sand are separated and conveyed to a conveyor belt. What was separated and separated into roughly three species was to recycle the foundry sand effectively by repeating the process of crushing and returning to the initial process.

폐주물사란 주물공정후에 배출되는 형틀 모래로서 그 배출량이 생산제품의 중량 대비 약 25%로 대단히 많아 폐주물사 처리에 고심하고 있는 실정이다.The waste foundry sand is mold sand discharged after the casting process, and the amount of the waste sand is about 25% of the weight of the produced product.

종래에는 폐주물사를 매립하는 소극적 방법을 택하여 처리하여 온바, 매립지 부족 현상을 초래하고 재사용할 수 있는 금속, 모래, 벤토나이트 등의 자원이 그대로 매립됨으로서 많은 경제적 손실을 가져오는 등 다수의 문제점이 있었다.Conventionally, there have been a number of problems, such as by taking a passive method of embedding the waste foundry sand, causing a shortage of landfills, landfill shortage and reusing resources such as metal, sand, bentonite, etc. that can be reused.

본 고안은 이와같은 문제점을 해결하기 위해 폐주물사를 약 40매쉬, 30매쉬, 1매쉬로 구분할 수 있는 선별기를 제공코자 한것으로 이하 첨부된 도면과 관련하여 상세히 설명하면 다음과 같다.The present invention is to provide a sorting machine that can be divided into about 40 mesh, 30 mesh, 1 mesh waste foundry sand to solve this problem described in detail with reference to the accompanying drawings as follows.

A tertiary conveyor belt (8) is installed at the outlet of the roller mill (7) up to the starting point of the secondary conveyor belt (5), and the secondary magnet roller (9) at the final end of the traveling direction of the tertiary conveyor belt (8). It is configured to separate and collect the second metal by installing the second magnetic rollers (4) and (9) in each of the sled plate (10) (11) is installed so that the magnetic force does not fall is configured to drop the metal. .

도면의 미설명 부호 (8')는 3차 콘베어벨트(8)를 통과한 폐주물사가 2차 콘베어벨트(5)상에 낙하되도록 하는 연결구이고, (20)은 홉퍼에 설치된 걸름망체, (21)은 수거용기,(23)(24)(25)는 배출구를 표시한 것이다.Unexplained reference numeral 8 'in the drawing is a connector for allowing the waste casting sand that has passed through the tertiary conveyor belt 8 to fall on the secondary conveyor belt 5, and 20 is a strainer installed in the hopper, 21 (23), (24) and (25) are the outlets.

이와같이 구성된 본 고안의 작용 및 효과에 대하여 상세히 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above in detail.

폐주물사에는 금속과 자갈, 모래, 벤토나이트 등이 서로 섞여있는데 이를 홉퍼(2)에 투입하면 1차 홉퍼(2)에 형성된 걸름망체(20)에 의해 이물질은 걸러진다. 그리고 낙하된 폐주물사 등은 1차 콘베어벨트(3)를 따라 이송되어 자석로울러(4)에 이르면 금속은 자력에 의해 회수되면서 자력이 소실되는 지점에서 낙하되어 썰매판(10)을 따라 이동하여 모이고 나머지는 2차 콘베어벨트(5)를 따라 회전망(6)에 투입되면서 40매쉬, 30매쉬, 1매쉬로 구분되어 차례로 배출구(23)(24)(25)로 배출되고 회전망(6)을 통과한 덩어리는 로울러 분쇄기(7)에 의해 분쇄되고 배출되면서 3차 콘베어벨트(8)에 의해 이송되어 2차 자석로울러(9)에 의해 금속은 회수되어 분리되고 나머지는 연결구(8')에 의하여 다시 2차 콘베어벨트(5)에 낙하되어 회전망(6)으로 투입되는 과정이 반복되면서 폐주물사에 섞여있는 자갈, 굵은 모래, 미분(벤토나이트 포함), 금속이 분리되는 것이다.The waste foundry sand is mixed with metal, gravel, sand, bentonite, etc., and when it is put into the hopper 2, the foreign matter is filtered by the filter mesh 20 formed in the primary hopper 2. Then, the dropped waste sand, etc. is transferred along the primary conveyor belt (3) and reaches the magnetic roller (4). The metal is collected by the magnetic force, falls from the point where the magnetic force is lost, moves along the sled plate (10), and gathers the rest. Is divided into 40 meshes, 30 meshes, and 1 mesh while being introduced into the rotary net 6 along the secondary conveyor belt 5 and discharged to the outlets 23, 24 and 25 in turn, and pass through the rotary net 6 One lump is crushed and discharged by the roller mill 7 to be transported by the tertiary conveyor belt 8 so that the metal is recovered and separated by the secondary magnet roller 9, and the rest is reconnected by the connector 8 '. Falling to the secondary conveyor belt (5) is introduced into the rotating network (6) is repeated, the gravel, coarse sand, fine powder (including bentonite), metal mixed in the waste foundry sand is separated.

이상과 같이 반복되는 과정에서 금속과 굵은 모래, 자갈, 미분(벤토나이트 포함)을 회수하여 재활용함으로서 매립지가 필요없고 환경보호와 경제적인 이득을 얻을 수 있는 매우 실용적인 고안이다.By repeating the above process of recovering and recycling metals and coarse sand, gravel and fine powder (including bentonite), it is a very practical design that does not require landfills and obtains environmental protection and economic benefits.
