PURPOSE:To obtain a filtration device having a structure suited to construct easily a large sized device and having functionally high efficiency by providing in combination an oscillating mechanism to an elastic spring strainer. CONSTITUTION:A perforated plate 2 is provided in a housing 1 to intercept the stream 3 of the filtrate. An elastic spring 5 made of a magnetic body is provided vertically in front of the perforations 4 on the perforated plate 2, further, an oscillating mechanism 6 for oscillating the spring 5 is provided to the rear of the perforated plate 2. The filtrate is activated by impressing a variable magnetic field to the filtrate. Since the spring 5 is magnetized, particles of magnetic bodies in the filtrate are attracted to the spring 5 and filtered. Particles of non- magnetic bodies are separated from the filtrate by the oscillation of the spring 5 and settled to the bottom of the device. The filtrate discharged from the perforation 4 are feed of both magnetic and non-magnetic particles to maintain a usual cleaned condition in which molecules of fluid are activated. |
