|発明の名称||CLEANING DEVICE USING MAGNETIC MATERIAL|
PROBLEM TO BE SOLVED: To provide a cleaning device using a magnetic material which sufficiently exhibits the capturing function of all floating solid materials to the total amount of water to be treated passing through a floating solid material recovery region having a filter and replaces the filter without generating/ extinguishing a magnetic field in the recovery region, and can maintain a continuous operation.
SOLUTION: Bulk magnets are arranged to a conduit, which are opposed to each other across the flow of the water to be treated inside the conduit so that the magnetic field is formed along the flow. Further, a filter to be inserted into the floating solid material recovery region is provided so that the floating solid material flowing through the flow path is captured in the region formed halfway through the flow path across the magnetic field. A plurality of sets of the filters are attachably/detachably set at supports for replacement and one set is selectively inserted into the recovery region by operating the support for replacement.
