Be positioned at the mechanical sealing linkage ring of tank interior, back-up ring, froth breaking oar are Split type structure, and back-up ring is arranged on for compression and stirs
Mix the mechanical sealing linkage ring on axle, cause mechanical sealing linkage ring and the stationary ring being positioned at cover locating slot mutually compresses, it is ensured that be anti-
Answer in device the sealing of gas to form tank pressure；Froth breaking oar is usually mounted on the shaft between liquid level and cover, according to liquid level
Height can carry out high high adjustment with foam situation, with control foam position height.
Owing to microreactor axial dimension requires less, as used traditional structure, the position of froth breaking oar will reduce, shadow
Ring the coefficient of microreactor, in the confined space, add the difficulty of operation and maintenance simultaneously.
Summary of the invention
It is an object of the invention to provide a kind of combination type froth breaking oar and use the miniature organism reactor of combination type froth breaking oar,
On the basis of not affecting defoaming function, effectively reduce the axial space of miniature organism reactor, it is simple to clean and safeguard, letter
Internal structure and the operation requirement of the microreactor for high flux screening are changed.
The technical scheme that the present invention provides is as follows:
A kind of combination type froth breaking oar, comprising: a pair blade and back-up ring, the pair of blade is horizontally set on outside back-up ring
Enclose, and the pair of blade place passes straight through the geometric center of back-up ring.
Concrete, a pair blade is arranged on the outer ring of back-up ring, its position level of relative, blade place pass straight through gear
The geometric center of circle.
It is further preferred that the bottom of described blade is provided with zigzag structure, or flat impeller structure, or orthogonal circle
