Title:
MAGNETISM SEPARATION/RECOVERY DEVICE
Document Type and Number:
WIPO Patent Application WO/2005/087381
Kind Code:
A1
Abstract:
In a magnetism separation/recovery device, a moving body (120) is rotated by movement of a magnetic substance-containing liquid (1) introduced into an annular flow path (110) from a flow path (112) for introducing the magnetic substance-containing liquid. Swarf (1B) in the magnetic substance-containing liquid (1) is attracted to the circular cylinder-like drum (122) side by a permanent magnet (130) provided in a predetermined region on the inner peripheral surface of the moving body (120) and carried in that state as the moving body (120) rotates. A cutting fluid (1A) from which the swarf (1B) is separated is discharged outside from a cutting liquid- discharging flow path (114). Because the swarf (1B) carried with the rotation of the moving body (120) passes through a magnetic region (MA), a magnetic force from a magnetic member (130) does not act on the swarf (1B) and the swarf (1B) passes a magnetic substance-discharging flow path (116) by free fall and is recovered into a magnetic body recovery box (118). The magnetism separation/recovery device can separate and recover magnetic substances such as swarf and metal powder contained in a liquid without drive power or with reduced power, and with magnetism.
