DEVICE AND METHOD FOR LUBRICANT FEED Russian patent published in 2014 - IPC B05B7/04 B05B15/02 

FIELD: process engineering.

SUBSTANCE: invention relates to lubrication of the rod of mechanical cleaning of feeder of several components. This device comprises mixing head for mixing of at least two fluid components. Mixing head has inlets for at least two fluids and mixing module arranged between them. Feeder comprises cleaning rod arranged inside mixing head to slide therein. Cleaning rod can get in front position whereat flow from inlets is shut off and in rear position whereat said fluid components flow from inlets into mixing module. Cleaning rod is displaced between said two positions by appropriate drive. Besides, this device comprises lubing chamber arranged behind said mixing chamber accommodating cleaning rod to slide therein. Lubricant is fed to cleaning rod inside lubing chamber. Beside, feeder has cartridge with lubricant and communicates with lubing chamber. Said feeder can comprises mixing mechanism secured to the housing for mixing of at least two fluid components. Proposed method comprises provision of first increased pressure for first fluid, second fluid and in cartridge with lubricant. Besides, this method comprises displacement of cleaning rod backward for mixing said component in mixing chamber. Then cleaning rod is continuously lubed with lubricant at pressure at ruled out ingress of lubricant into mixing chamber.

EFFECT: simplified servicing and replenishing.
