Problems solved by technology
[0003] Since the electrodeposited zinc electrode is generally directly electrodeposited on one side of the copper foil, and the structure of the active material of the electrodeposited zinc electrode is relatively loose, the active material is relatively easy to fall off and be damaged.
Therefore, it is generally impossible to use the washing device and method of the hanging type (fixing one side of the pole plate, and then hanging it on the washing rack), and generally only adopts the washing method of the tiled type (laying the pole plate on a single-layer washing rack)
Currently known zinc-silver reserve batteries only have the washing methods of hanging type (fixing one side of the pole plate and then hanging it on the fixing frame) and tiling type (laying the pole plate on a single-layer fixing frame). Neither can fix electrodeposited zinc electrodes

The invention relates to an electric deposition zinc electrode washing device. The electric deposition zinc electrode washing device comprises a fixing frame and a clamping plate, wherein the fixing frame comprises a bottom plate and two symmetrically arranged positioning shafts, the bottom ends of the positioning shafts are fixed on the bottom plate, through holes are formed in the two ends of the clamping plate, the clamping plate can string on the two positioning shafts, and one or more clamping plates are arranged. The electric deposition zinc electrode washing device has the beneficial effects that the zinc electrode is fixed on the clamping plate through the clamp, the damage of the zinc electrode caused by the flow of the cleaning liquid, the movement of the washing device and the like in the cleaning process is avoided, and the damage rate of the zinc electrode in the process is reduced; the plurality of clamping plates can also be stacked together according to needs, the spaceutilization rate of the washing tank is improved, and the plant site occupied by the washing tank is reduced; and the cleaning liquid in the washing tank is fully utilized, the utilization rate of the cleaning liquid is improved, and the dosage of the cleaning liquid is saved.
Description
technical field [0001] The invention belongs to the technical field of electrode plate preparation for reserve batteries and accumulators, and in particular relates to an electrodeposited zinc electrode cleaning device and a cleaning method. Background technique [0002] Zinc-silver storage batteries are widely used in various fields due to their high specific energy, high specific power, large current discharge, stable discharge voltage, high voltage accuracy, reliability and safety. At present, traditional paste-coated or powder-pressed zinc electrodes are widely used. Compared with them, electrodeposited zinc electrodes are highly active electrodes, which can have higher specific surface and porosity. The uniformity is good, and it is suitable for discharging under the requirement of high current density and short time, so it is mainly used in bipolar zinc-silver reserve batteries. [0003] Since the electrodeposited zinc electrode is generally directly electrodeposited ...
