Abstract

The invention relates to electrolytic deposition equipment in the technical field of chemical industry, in particular to a circulation system device for a closed frame-type electrolytic nickel or electrolytic cobalt electrolyte. The device is firstly equipped with a cathode frame and an anode frame in the electrowinning cell, and a permeable membrane is arranged between the cathode frame and the anode frame. The electrolytic cell is filled with electrolyte, and the electrolyte flows into the cathode along with the electrolyte inlet provided on the cathode frame Then enter the anode frame from the permeable membrane under a certain pressure, the anolyte after electrolysis flows to the connected branch pipe through the outlet at the lower end of the anode frame, and the liquid in the branch pipe is combined and then discharged to the anolyte overflow port and discharged from the electrowinning cell. Instead of relying on the diaphragm frame and diaphragm sleeve, the distance between the same poles in the electrowinning cell is greatly shortened, and the utilization rate of the cell is improved. Low power consumption saves production cost. It is not necessary to lift the cathode and anode out of the electrowinning tank every time through manual labor, and it is not necessary to use labor to cover the diaphragm bag on the diaphragm frame, which saves labor.

Description

technical field

[0001] The invention relates to electrolytic deposition equipment in the technical field of chemical industry, in particular to a circulation system device for a closed frame-type electrolytic nickel or electrolytic cobalt electrolyte. Background technique

[0002] The traditional nickel or cobalt electrodeposition devices adopt diaphragm electrodeposition structure. There are two kinds of diaphragm electrodeposition structures. One is that the cathode is placed in the diaphragm bag of the cathode chamber, and the cathode in the electrolytic cell needs to be placed in the diaphragm. In the bag, the diaphragm bag must be supported by a diaphragm frame. If the diaphragm frame is placed in the electrowinning tank, it will inevitably occupy the space in the tank, so that the distance between the same poles must be above 120-130mm. Another type of diaphragm is to use The anode is set in the diaphragm bag of the anode chamber. For the same reason, the distance betw...
