Novel emulsion liquid scavenge unit described in the utility model, its structure are that described nozzle is quiet nozzle.
Novel emulsion liquid scavenge unit described in the utility model, its structure are that the described anti-angle that twines the nozzle of the purging belt steel surface on the guide plate of top working roll that is installed in is that nozzle-axis becomes 30～50 degree angles with band steel plane.
Novel emulsion liquid scavenge unit described in the utility model, its structure are that the described angle that is installed in the nozzle at the roll gap place that is positioned at working roll and intermediate calender rolls on the frame is that nozzle-axis becomes 5～20 degree angles with band steel plane.
Novel emulsion liquid scavenge unit described in the utility model, its structure are that the described anti-air amplifier that twines on the guide plate of bottom working roll that is installed in is made up of a plurality of, become biserial to arrange alternately.
The beneficial effects of the utility model are:
1, making the anti-shovel of top working roll guide plate, the anti-shovel of bottom working roll guide plate have dual-use function, promptly is that upper working rolls and lower working rolls prevents that twining guide plate is again the emulsion blow device.
2, owing in the device of the present utility model,, make slit, guide plate upper edge form a gas curtain, can stop emulsion to drip on the belt steel surface effectively from top working roll in the anti-guide plate front end shovel slit that the place has that twines of top working roll.
3, owing to be provided with nozzle, can purge working roll and intermediate calender rolls roll gap place, thereby can prevent that emulsion from entering into the outlet side of milling train from the entrance side of milling train at the roll gap place of working roll and intermediate calender rolls.
4, adopt advanced quiet nozzle, can reduce the noise of working site.
5, at the anti-rear portion that twines guide plate of bottom working roll the air amplifier is set, utilizes the swabbing action of air amplifier to take away the emulsion of belt steel surface, realized the purging purpose that pressure-vaccum combines.
