Abstract

A magnetic separator of rotating drum type is provided to prevent raw materials from being discharged together with iron through an iron discharge port by using a brush and to control the input amount of the raw material by installing an input amount regulator at a raw material input port of a housing. In a magnetic separator of rotating drum type, a permanent magnet-type pulley(20) is disposed in a housing(10). Both ends of a fixed shaft of the permanent magnet-type pulley are fixed to both sides of the housing. Both ends of a rotating drum(30) are supported by bearings fitted to both ends of the fixed shaft, respectively. Accordingly, the rotating drum turns relatively to the pulley by the bearings. A sprocket(32) installed at one end of the rotating drum and a motor(40) disposed at the outside of the housing are connected by a chain(41). A brush(50) is rotatably mounted at the lower side of the rotating drum in the housing. A sprocket(51) installed at one end of the brush and the motor are connected by the chain. A permanent magnet of the pulley is formed in an arc shape on a predetermined section of the pulley and disposed between the part adjacent to an input port and the upper side of an iron discharge port(12) via the position where the brush is installed.

Both ends of the rotating drum 30 are supported by bearings 31 fixed to both sides of the housing 10 and fitted to both ends of the fixed shaft 21, so that the rotating drum 30 is connected to the bearing 31. It is possible to rotate relative to the permanent magnet pulley 20, the sprocket 32 mounted on one end of the rotary drum 30 and the motor 40 disposed outside the housing 10 to the chain 41 The sprocket 51 and the motor 40 mounted on the housing 10 are rotatably mounted to the housing 10 so that the brush 50 is rotatably mounted on the lower portion of the rotating drum 30. Connected by 41, and as shown in Figure 2, the permanent magnet 22 of the permanent magnet pulley 10 of the permanent magnet pulley 20 Unit is arranged in a circular arc shape in section, is disposed between the permanent magnet 22, the input port (IN) of the brush arrangement (51) in the vicinity of the location through the upper position of the iron powder outlet 12.

도 3을 참조하면, 상기와 같이 구성된 본 발명에 따른 회전드럼식 마그네틱 분리기는 모터(40)의 구동에 의해 회전드럼(30)이 도 3의 화살표(61) 방향으로 하우징(10)에 고정된 영구자석식 풀리(20)에 대해 상대 회전하게 되면, 하우징(10)의 원료 공급구(11)로 공급된 원료(70)가 투입구(IN)를 통과하여 원료 배출구(13)로 배출된다. 이 과정에서 영구자석(22)의 자력에 의해 원료에 포함된 철분(72)이 회전드럼(30)에 부착되어, 투입구(IN)를 통과한 원료(70)에서 철분(71)이 분리되므로서, 철분이 제거된 순수한 원료(72)만이 원료 배출구(13)를 통해 배출되고, 회전드럼(30)에 부착된 철분(71)은 영구자석(22)이 없는 비자성구간(a)에 도달되면 회전드럼(30)으로부터 분리되어 철분 배출구(12)로 배출된다. 이때, 회전드럼(30)에 부착된 철분(71)이 브러쉬(50)를 통과하는 과정에서 철분(71)에 섞여 있는 원료가 브러쉬(50)에 의해 철분에서 분리되어 원료배출구(13)로 배출되고, 철분(71)은 영구자석(22)이 배치된 자성구간(b)에 있기 때문에, 영구자석(22)의 자력에 의해 회전드럼(71)에서 탈락되지 않는다.Referring to FIG. 3, the rotary drum magnetic separator according to the present invention configured as described above is permanently fixed to the housing 10 in the direction of the arrow 61 of FIG. 3 by the driving of the motor 40. When the relative rotation with respect to the magnetic pulley 20, the raw material 70 supplied to the raw material supply port 11 of the housing 10 passes through the inlet (IN) is discharged to the raw material outlet (13). In this process, the iron powder 72 included in the raw material is attached to the rotating drum 30 by the magnetic force of the permanent magnet 22, and the iron powder 71 is separated from the raw material 70 passing through the inlet IN. When only the pure raw material 72 from which iron is removed is discharged through the raw material outlet 13, and the iron 71 attached to the rotating drum 30 reaches the nonmagnetic section a without the permanent magnet 22. Separated from the rotating drum 30 is discharged to the iron outlet (12). At this time, the raw material mixed in the iron 71 is separated from the iron by the brush 50 in the process of passing through the brush 50, the iron 71 attached to the rotary drum 30 is discharged to the raw material outlet (13) Since the iron powder 71 is in the magnetic section b in which the permanent magnet 22 is disposed, the iron powder 71 does not fall off the rotating drum 71 by the magnetic force of the permanent magnet 22.
