Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure: whisking appliance Combination application of the present invention is on large fermentation tank, and it mainly is made up of stir shaft 1, froth breaking whisking appliance 2, axial flow upper-turn-type whisking appliance 3 and disc turbine formula whisking appliance more than 4 parts.
As shown in Figure 1, said stir shaft 1 bottom is supported through base bearing 5, and stir shaft 1 is positioned at the intravital part of fermentor tank and is from up to down fixing froth breaking whisking appliance 2, three layers of axial flow upper-turn-type whisking appliance 3 and disc turbine formula whisking appliance 4 successively.
As shown in Figure 1, said froth breaking whisking appliance 2 has two blade 2a that are 180 ° of symmetrical distributions, and blade 2a is along being distributed with a plurality of fin 2b perpendicular to blade 2a on its length direction.The wheel hub of said froth breaking whisking appliance 2 is made up of two semi-circular wheel hubs, and two semi-circular wheel hubs are to piecing together and being fixedly clamped on stir shaft 1, and described two blade 2a are weldingly fixed on respectively on two semi-circular wheel hubs.
As shown in Figure 1, said axial flow upper-turn-type whisking appliance 3 has four cambered blade 3a, and the side that cambered blade 3a meets to feed liquid when rotating is a flat shape, and the opposite side arc-shaped bend is upturned.The wheel hub of said axial flow upper-turn-type whisking appliance 3 is weldingly fixed on the stir shaft 1, and cambered blade 3a passes through screw retention on wheel hub.Because wheel hub and stir shaft 1 are to be welded to connect, and have eliminated the gap between wheel hub and the stir shaft 1, have reduced the probability of fermentor tank microbiological contamination, also convenient simultaneously the cleaning.
