Filtering device for cleaning and cooling plating layer

The invention relates to the technical field of aluminum and zinc plating production line cooling devices, in particular to a filtering device for cleaning and cooling a plating layer. The filtering device for cleaning and cooling the plating layer comprises a filtering shell and an air outlet pipe, the filtering shell is in a U shape, a sewage discharging shell is arranged at the bottom of the filtering shell, a water inlet pipe is connected to the sewage discharging shell in the axis direction, the upper portion of the water inlet pipe is located in the filtering shell, and a plurality of water filtering plates are connected to the inner side of the air outlet end of the filtering shell; the air outlet pipe is connected with the air outlet end of the filter shell. Inlet air is filtered and cleaned through the filter shell, dust and other impurities in the inlet air are effectively removed, meanwhile, the inlet air can be cooled, the cooling effect on a plating layer is improved, and the influence on the pla
