| 摘要 |
The invention relates to a cooled calibrating device for a plastic extrusion facility, comprising a housing ( 5 ) receiving a cooling liquid ( 2 ) and calibrating guides ( 6 ) through which a plastic profile ( 1 ) is passed, in addition to inlet and outlet holes ( 10, 23 ) having attached lines for the cooling liquid, wherein an area ( 21 ) free of liquid and filled with air remains above the level of the cooling liquid. An outlet hole ( 10 ) for the cooling liquid is arranged at the height of the cooling liquid level ( 20 ) in the calibrating device so that the cooling liquid can flow out without an additional pump. An outlet line ( 11 ) attached to the outlet hole extends vertically and ends in a cooling liquid reservoir ( 12 ) that is subjected to an external atmosphere, wherein a compact liquid column ( 24 ) is formed in the outlet line ( 11 ). |
