Design method for sampling unit for concentrates preparation device Abstract The invention relates to a design method for the sampling unit for the concentrates preparation device using low pressure and low boiling point. The method comprises arranging for the sampling chamber to pass through the upper and lower surfaces of the base body; 5 arranging for the isobaric chamber to pass through the front surface of the base body and to pass through the front and back surfaces of the sampling chamber. Arranging for the axle sleeve to have an interference fitting with the isobaric chamber; arranging for the movable rod to hermetically slidingly mate with the axle sleeve; 10 arranging for the head and tail ends of the gas permeable passage to respectively communicate with the isobaric chamber and the outside. When the sampling unit takes samples from the boiler, it is no necessary to stop concentration process or to open the upper cover of the boiler. Concentrates can be taken out through the sampling 15 bore of the sampling unit, the movable rod can take samples freely with the help of gas permeable passage for keeping the pressure balance of ends of the movable rod. 1407., oloo 140 6 <140 5 Fig. 8 |
