Abstract

The invention provides a liquid purification device capable of reducing installation area and omitting operations of removing sludge and cleaning. The device includes a first container (1) containing sludge liquid, a second container (2) in the first container and keeping a proper height from the bottom surface of the first container, communication ports (21,22,23,24) arranged in the bottom surface of the second container and communicating with the first container, a magnetic field applying unit (3) generating magnetic field in a plurality of areas of the bottom of the first container (1c), a guide unit (4) flexibly connected with the bottom of the first container and guiding sludge to the side wall of the first container, and a sludge recovery unit (5) arranged at at least one part of the side wall of the first container.

Description

technical field [0001] The present invention relates to a liquid purifying device, and more particularly to a device for purifying liquids such as coolant used in machine tools. Background technique [0002] Metal shavings generated during grinding etc. are mixed in liquids such as coolants used in machine tools such as grinding apparatuses, so attempts have been made to remove the metal shavings (magnets) from the liquid by magnetically attracting them (see Patent Document 1 and 2). However, since abrasive grains and the like are mixed in liquids such as coolants used in grinding machines and the like in addition to metal chips, further filtration is required. Therefore, the applicant of the present invention has developed a filtration device that removes fine sludge in two steps of primary filtration and secondary filtration (see Patent Document 3).
