The electrolyte inside passage of second series connection single battery group, finally comes together in pile central dividing plate；The pile end plate has electrolyte
Passage leads to the electrolyte inside passage of the series connection single battery group of respective side, finally comes together in respective pile end plate；The electricity
The electrolyte polarity of heap central dividing plate and the electrolyte opposite polarity of pile end plate.
The pile central dividing plate has side lower part of the central dividing plate electrolyte entrance in pile central dividing plate, has with upper lateral part
Central dividing plate electrolyte outlet；The pile end plate has side lower part of the end plate electrolyte entrance in pile end plate, has with upper lateral part
End plate electrolyte outlet.
The central dividing plate electrolyte entrance, central dividing plate electrolyte outlet and end plate electrolyte entrance, end plate electrolyte
Export not homonymy.
The electrolyte passage of the pile end plate of the both sides is logical respective independent, does not interfere with each other.
The dividing plate thickeied is installed between the most middle monocell of vanadium cell heap additional, sky is provided for electrolyte side feed liquor
Between, also the monocell of series connection is separated, leakage current is reduced.
Pile reinforcing plate is added on the outside of the pile end plate.
The beneficial effects of the invention are as follows：
1st, the present invention can not only reduce the caused leakage current of multiple monocells directly series connection, also be two entities of design
Vanadium cell heap connect reduce cost again.
2nd, the positive and negative level inlet of pile and liquid return hole are arranged in pile both sides, reduce both positive and negative polarity fluid reservoir and pile
The pipeline of connection, simple in construction, easy later maintenance.
