The utility model relates to plate
pickling treatment technical field discloses a kind of
pickling spray
production line for plate, including bottom plate, the top of the bottom plate is fixedly connected with
pickling spray tank, the both sides of pickling spray tank are fixedly connected with conveying roller stand and
discharge roller stand in the top of the bottom plate, so that the device can filter the
metal particles in waste liquid by filter plate, then the filtered waste liquid is pumped into the inside of circulating
recovery tank by pumping, and the acidity of waste liquid in the inside of circulating
recovery tank is detected using PH sensor, when acidity is too low, it can add acidic solution with higher concentration to the inside of circulating
recovery tank by liquid supplementing tank, so that the acidity of solution in the inside of circulating recovery tank can be kept in suitable pickling range, finally, pickling and spraying treatment of plate can be quickly carried out using high-pressure atomizing
nozzle at the bottom of spray
pipe, so that the acid liquor recovery rate of the device is greatly improved.
