Fig. 2 is the left side schematic diagram of Fig. 1.
In figure：1, top cover board；2, side overflow orifice plate；3, bottom cover plate；4, side closure plate；5, lower part trapezoidal plate.
Specific implementation mode
The present invention can be explained in more detail by the following examples, open the purpose of this utility model is intended to protection originally
All changes and improvements within the scope of utility model, the utility model are not limited to the following examples：
The electrolyte overflow mechanism for high density silver electrolytic cell in conjunction with described in attached drawing 1~2, the device include upper
Portion's cover board 1, side overflow orifice plate 2, bottom cover plate 3, side closure plate 4 and lower part trapezoidal plate 5；1 bottom surface of top cover board
Correspondence is fixedly connected two long side edge with the top surface of a side spout hole plate 2 and a side closure plate 4 respectively, and side overflow orifice plate 2
It corresponds to the bottom surface of side closure plate 4 and is fixedly connected with the top surface edges Liang Chang of bottom cover plate 3 respectively, that is, pass through top cover board 1, side
Portion's overflow orifice plate 2, bottom cover plate 3 and side closure plate 4 surround jointly to be formed one hollow, and side is trapezoidal trapezoidal flume；
