DEVICE FOR PREVENTING DEPOSITION IN LIQUID SPRAYING NOZZLE BY USE OF MAGNET TO PREVENT FOREIGN BODIES FROM BEING DISPOSED IN SPRAYING NOZZLE

摘要

PURPOSE: A device for preventing deposition in the liquid spraying nozzle by use of a magnet is provided to prevent foreign bodies included in liquid from being deposed in the spraying nozzle, and shutting off spraying passage. CONSTITUTION: The device for preventing deposition in the liquid spraying nozzle includes a flexible tube(56), a filter(64) mounted on the flexible tube(56), a follower magnet(66), and a driven magnet(24). The flexible tube(56) connects a header(10) and a liquid spraying nozzle(50). The filter(64) filters foreign bodies included in the liquid supplied from the flexible tube(56). The follower magnet(66) is fixed to the filter(64). The driven magnet(24) moves along the predetermined route inside the header(10), giving magnetic force to the follower magnet(66).
