Abstract: Provided is a magnetic separator in which even when content of a magnetic sludge in a liquid to be treated increases, recovery performance of the magnetic sludge is less likely to degrade and a malfunction of the device is less likely to occur. A part of an outer peripheral surface of a magnet drum is immersed in a flow of the liquid to be treated containing the magnetic sludge. A removing mechanism removes the magnetic sludge on the outer peripheral surface of the magnet drum from the outer peripheral surface of the magnet drum. A magnetic sludge containing information acquisition device acquires magnetic sludge containing information relating to a content of the magnetic sludge contained in the liquid to be treated. A control device changes a magnetic sludge removal capability of the magnet drum depending on the magnetic sludge containing information acquired by the magnetic sludge containing information acquisition device.

Abstract: A magnetic separator includes: a scraper configured to channel a liquid through an opening portion to a flow pathway, the scraper extends from a sub-drum to the opening portion; a first bottom wall configured to channel the liquid along the flow pathway in a manner that channels the liquid away from the opening portion, the flow pathway is between a main drum and a curved surface of the first bottom wall; and a second bottom wall configured to channel the liquid along a lower flow path in a manner that channels the liquid to the opening portion, the lower flow path is between the sub-drum and a curved surface of the second bottom wall.

Abstract: Provided is a liquid circulation device for a machine tool including a tank which has an introduction portion and a lead-out portion of a liquid, and in which a liquid circulated between the liquid circulation device and the machine tool is stored; and a heat exchanger disposed in the tank, in which the tank has a throttle portion in which a cross-sectional area of a liquid passage between the introduction portion and the lead-out portion is reduced and a first storage portion on the introduction portion side from the throttle portion, and at least a portion of the heat exchanger is disposed between a center of the first storage portion and the throttle portion.

Abstract: A drum type separation apparatus includes a liquid passage that allows a liquid mixed with a magnetic body to pass therethrough, a rotary drum that is disposed such that a part of the rotary drum is exposed above a liquid surface in the liquid passage, and transports the magnetic body adsorbed on an outer peripheral surface as the rotary drum rotates, and a magnet that is disposed on an inner side of the rotary drum, in which a magnetic force on a side lower than the liquid surface from an intersection position where the rotary drum and the liquid surface intersect each other is larger than a magnetic force on a side higher than the liquid surface from the intersection position.

Abstract: A coolant liquid processing system includes: 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.

Abstract: A rotary drum-type magnetic separator includes a first rotary drum on which a plurality of magnets are disposed and separates unnecessary objects from a used coolant liquid. A second rotary drum on which a plurality of magnets are disposed is provided before the first rotary drum in a direction in which the used coolant liquid flows separately from the first rotary drum. The second rotary drum includes an outer tube and an inner tube. A scraper which scrapes off the unnecessary objects attached to the second rotary drum is connected to a bottom member which forms a flow path below the first rotary drum.

Abstract: A magnetic separator includes: a main drum which discharges magnetic sludge to the outside of a liquid to be treated; and a sub-drum which is disposed on the upstream side of the main drum and magnetizes the magnetic sludge in the liquid to be treated, in which the sub-drum is disposed in a state of being immersed in the liquid to be treated, an upper flow path through which the liquid to be treated flows is formed above the sub-drum, and a lower flow path through which the liquid to be treated flows is formed below the sub-drum.

Abstract: A printing position and cutting position adjusting method includes: printing on a medium an origin point adjusting image having multiple checking blocks using an ink-jet head; cutting the medium using a cutting head along a contour of the origin point adjusting image; removing a part of the medium cut by the cutting head from the medium; and inputting an amount of misalignment between a position at which the image is printed on the medium and a position at which the medium is cut to a controller. The amount of misalignment is inputted as a correction value between the printing position and the cutting position. The printing of the origin point adjusting image or the cutting of the medium includes a check process of producing a position shift per a predetermined dimension by each checking block in a main scanning direction or a sub scanning direction of the ink-jet head.
