The fine filtering part adopts a microporous filter core, which is regularly replaced according to the use condition, and is usually replaced according to the pressure difference indication of the filter device or the use time. When the filter core is replaced, the circulating pump 41 is closed, the old filter core is detached, the new filter core is installed, and the filter device is restarted after ensuring the good sealing. After each cleaning and replacement of the filter core, the maintenance time and the replaced filter core model should be recorded, so as to track the use condition of the filter device and ensure the filtering effect.

[0045] The working process of the anti-leakage environment-friendly electroplating tank is as follows:

[0046] 1. Inlet and outlet of the electroplating solution and circulation:

[0048] During the electroplating process, the electroplating solution continuously circulates and flows through the electroplating solution circulating and filtering system 4, so as to maintain the uniformity and stability of the electroplating solution. Specifically, the circulating pump 31 is started, the electroplating solution is pumped out from the liquid outlet 15 at the bottom of the tank body 1, the impurities in the electroplating solution are filtered out through the filter device 42 on the liquid outlet pipe 17, and then the electroplating solution is sent back to the tank body 1 through the liquid inlet pipe 16.

[0049] 2. Anti-leakage monitoring:

[0050] Normally, the sealed space between the inner tank 11 and the outer tank 12 is free of liquid. When the inner tank 11 leaks, the leaked plating solution will enter the sealed space, and the liquid level sensor 13 will detect the change in liquid level and promptly issue an alarm to remind the staff to handle it. The leaked plating solution can be discharged through the leakage liquid outlet 18 and the leakage liquid outlet pipe.

[0051] 3. Waste gas treatment:

[0052] The waste gas generated during the electroplating process enters the exhaust pipe 22 through the exhaust port 21 on the tank cover 2, and at the same time the air suction hood 41 above the tank 1 collects the overflowed waste gas and discharges it through the ventilation duct 42. The waste gas is first introduced into the spray tower 43 to fully contact with the spraying liquid, removing most of the acidic gas and particulate matter, and then enters the activated carbon adsorber 44 to further adsorb the remaining organic waste gas. The treated waste gas meets the environmental protection emission standard before being discharged into the atmosphere.

[0053] The above is only the preferred embodiment of the present application, it should be pointed out that for those skilled in the art, without departing from the principles of the present application, can make a number of improvements, these improvements should also be considered as the protection scope of the present application.
