The cleaning water system of the insulating glass production line is a circulating system, and its water tank is equipped with a constant temperature water heating device, which can automatically maintain the water temperature within a reasonable range. Water is pumped out of the water tank by a water pump and sprayed onto the surface of the glass through a spray pipe. After cleaning the glass, it flows back to the water tank for recycling. If the water quality is poor, a water treatment device (provided by the user) needs to be equipped. After the water is treated, it enters the water tank and is recycled according to the above steps. Air duct system: The glass is blown dry by a fan through a pair of inclined blades.
