The invention discloses a guide rail type permanent magnet chain filtering system for cold-rolling cooling liquid treatment. The guide rail type permanent magnet chain filtering system comprises a magnetic chain mechanism, a pollution cleaning mechanism, a slag recycling mechanism and a motor transmission mechanism, wherein the pollution cleaning mechanism as a key improvement comprises a roller way unit with a space closed-loop structure, sleeve type slag scrapers correspondingly arranged on magnetic sticks in the length direction in a sleeved manner and guide components for connecting the roller way unit with the sleeve type slag scrapers; when the magnetic sticks drive the slag scrapers to do linear motion together along the chain transmission direction, the slag scrapers and the guide components are fixedly connected to do motion and are restrained by a trace of the roller way unit, and therefore, metal dust adsorbed by the magnetic sticks can be scraped off. According to the guide rail type permanent magnet chain filtering system, the phenomenon that a magnetic stick deforms or is damaged due to rigid contact between the pollution cleaning mechanism which moves to an extreme position and the magnetic stick can be effectively avoided; furthermore, the overall size of the system can be greatly reduced, and the running speed and the following efficiency can be obviously improved. The guide rail type permanent magnet chain filtering system can be widely applied to filtering, purifying and magnetic separation of various types of industrial water which contains iron dust and is adhered with dirt.
