Description

Technical Field

[0001] The utility model belongs to the technical field of electrolytic deposition devices, and in particular relates to a novel nickel electrolytic deposition tank diaphragm bag installation and replacement device. Background Art

[0002] At present, nickel electrowinning adopts the process of insoluble anode plus cathode diaphragm bag, and the production system is a sulfate system. The cathode liquid of electrowinning is introduced into the cathode diaphragm bag, and the diaphragm bag is penetrated to maintain the difference in the liquid level of the cathode and anode for electrowinning. The current cathode diaphragm bag process uses the diaphragm frame to assemble the entire tank and put it into the electrowinning tank, and then place the cathode diaphragm bag in each cathode area. There is no positioning and support, and the bag plate is prone to sticking during the electrowinning process, which affects the quality of electronickel.

[0003] Under the traditional process, since the diaphragm bag does not have a good fixing device, the diaphragm bag will move, causing the diaphragm bag under the electrodeposition sheet to float up and hit the electrodeposition sheet. As the electrodeposition proceeds, the nickel precipitated on the electrodeposition sheet will stick to the diaphragm bag. When it is taken out, the bag will be taken out, resulting in the phenomenon of bag sticking, affecting product quality. At the same time, there are multiple diaphragm bags installed in the electrodeposition tank. If they are taken out or installed one by one, the efficiency is low. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a novel nickel electrolytic cell diaphragm bag installation and replacement device.

[0007] The hanger includes a plurality of inverted T-shaped hooks and a push-pull structure for controlling the simultaneous horizontal rotation of the plurality of inverted T-shaped hooks. The inverted T-shaped hooks are arranged below the push-pull structure. The inverted T-shaped hooks extend into the diaphragm bag. The inverted T-shaped hooks are rotated to lift the through rod and the reverse-edge installation rod, thereby taking out the diaphragm bag and replacing it.

[0008] Furthermore, the push-pull structure includes an assembly frame, multiple groups of rotating connecting plates and push-pull plates. Multiple vertical limit through holes are respectively opened on both sides of the assembly frame. The upper end of each inverted T-shaped hook passes through the vertical limit through hole and is fixedly connected to one end of a corresponding group of rotating connecting plates. The other ends of all the rotating connecting plates on the same side are hinged to the push-pull plates on the corresponding side. The forward and backward movement of the push-pull plate drives the multiple groups of rotating connecting plates to rotate at the same time, thereby driving all the inverted T-shaped hooks to rotate.
