摘要： An object of the present invention is to suppress the movement of a magnet at the time of assembly in a magnetic drum and a magnetic separation device in which a plurality of magnets are disposed in a circumferential direction, and to easily assemble the magnetic drum. Further, an object of the present invention is to suppress a change in the disposition of the magnets so as not to impair the design function of the magnetic drum, in the magnetic drum after the assembly. In order to achieve the above objects, there are provided a magnetic drum in which a plurality of magnets are mounted along a circumferential direction on a holder, the magnets are disposed such that magnetic pole surfaces face each other along the circumferential direction on the holder, and the magnets are engaged with the holder so as not to move in the circumferential direction, and a magnetic separation device provided with the magnetic drum.

摘要： A device for suppressing slit clogging capable of maintaining recovery rates of ground particles without clogging of the ground particles in an opening is provided. The device for suppressing slit clogging is used in a rotating-drum type magnetic separator 1 which includes a rotating drum 3 on which a plurality of magnets 4 are disposed and separates unnecessary matters in treated coolant liquid. A slit-like opening 8 is provided below the rotating drum 3, and the device includes a cylindrical groove cam mechanism, which is configured by a cylindrical shaft 21 having a groove which can be rotated and a slit cleaning member 22 which engages with the groove, below the opening 8. The slit cleaning member 22 moves along a longitudinal direction of the opening 8.

摘要： An object of the present invention is to suppress the incorporation of sludge into a treatment liquid treated by a filtration device by quickly detecting a leakage of the sludge due to damage to a filter or the like in a coolant liquid treatment apparatus including the filtration device for filtering a coolant liquid containing sludge. In order to solve the above problem, there is provided a coolant liquid processing system including a filtration device for filtering a coolant liquid containing sludge, and a detector that detects particles in a treatment liquid filtered by the filtration device. According to the coolant liquid processing system, since the detector that detects particles in the treatment liquid is provided in a rear stage of the filtration device, a leakage of the sludge from a filter can be quickly noticed. In a case where the leakage of the sludge is detected, the incorporation of the sludge into the treatment liquid can be suppressed by taking measures such as immediately stopping the filtration device.
