[0002] Cobalt electrolysis is an electrochemical metallurgical process that uses electrolytic deposition or electrolytic refining to produce electrolytic cobalt from cobalt-containing clean liquid or crude cobalt. Acid mist is produced during the cobalt electrolysis process. Workers often use electrolytic cells with acid mist isolation protective covers to prepare cobalt. After the protective cover is opened, the acid mist will float upwards and needs to be sucked out and cleaned using a suction pump.

[0003] The existing public technical scheme, with announcement number CN220099222U, discloses a chemical machinery control protective device, including a sealing box and a sealing opening and closing plate. An air inlet is opened on one side above the outer surface of the sealing box. When replacing the electrode plate, the sealing box can ensure the sealing state of the electrolytic box to prevent acid mist leakage from causing harm to humans. At the same time, air is automatically intaken through the air inlet on the sealing box without the need to re-replenish air to balance the air pressure, which greatly simplifies the operating process and safety of replacing the electrode plate.

[0004] When the above technical solution is actually implemented, the position of the electrode plate needs to correspond to the position of the through port, otherwise the sealing box cannot be sealed. This in turn results in the electrode plate being unable to be adjusted according to actual use, which is inconvenient to use. Summary of the invention
