After the full-automatic operation of the machine is finished, the box cover of the oil tank 91 is opened, the elastic nut 141 of the hose clamp 14 is unscrewed, the hand-held folding plate 16 is held to move the filter bag 11 towards the oil return end 921 of the built-in cooler 92, when the bag opening of the filter bag 11 moves to the port of the oil return end 921 of the built-in cooler 92, the pulling rope 12 is pulled to close the bag opening, so that scrap iron and dirt are locked in the filter bag 11, and the filter bag 11 is taken out. Turning up the filter bag 11 that will take out, rub twice repeatedly in soaking clean hydraulic oil (because the outer wall can separate the impurity more than 50 microns in the filter bag 11, and consequently only need simply wash because of the nylon material characteristic can), shake off iron fillings and impurity, in turning up the filter bag 11 again afterwards and returning into the car of airing hanger 3, can use once more through 11 oil solution drippings of a night sunning filter bag, it is reserve to push away to the fuselage assembly line, turn up the filter bag 11 during the washing, interior external surface contactless, consequently, can not produce follow-up production fluid pollution problem because of the unclean of wasing.
