A magnetic filter (W1) provided with an outer cylinder (1) and inner cylinder (2) arranged concentrically, a filter chamber (12) formed in the gap between the outer cylinder (1) and the inner cylinder (2), and a magnet unit rod (3) accommodated in a removable manner inside the inner cylinder (2). A magnetic substance mixed in a filtrate flowing into the filter chamber (12) adsorbs to the outer peripheral surface of the inner cylinder (2) due to the magnetic force of the magnet unit rod (3) accommodated in the inner cylinder (2), a scraper (9) having scraping parts (9a) that come into contact with the outer peripheral surface of the inner cylinder (2) is placed in the filter chamber (12), and when the scraper (9) is operated, the scraping parts (9a) slide along the outer peripheral surface of the inner cylinder (2) and scrape off the magnetic substance adsorbed on the inner cylinder (2). |
