In order to ensure that the surface of the pulled steel wire is clean and powder-free, a cleaning equipment device is used for cleaning treatment. An appropriate (usually 1%) metal surface treatment agent is added to tap water, and the surface of the steel wire is washed by a high-pressure submerged pump (1.1KW). At the same time, a cleaning ball is used to wipe the surface of the steel wire in the passage. In order to ensure that the surface of the steel wire is wrapped without water before entering the winding line, So, at the outlet of the steel wire, a high-pressure air blowing device is used to vigorously blow the steel wire surface 360 ° without gaps, ensuring that there is no water vapor in the steel wire during winding. This cleaning machine is divided into two layers: upper and lower, with a steel wire passage layer on top. The specification is 400X300X2000, which is made of stainless steel welded material. Inside, there are nine adjustable cone wiping devices, which tightly contact the steel wire and the cleaning ball for wiping; The lower layer is a water storage tank, with a specification of 800X700X1600, which is welded from 4mm stainless steel plate. There is a filtering area in the water tank, and the filtered water is pumped out from the anti-corrosion liquid pump on the water storage tank into the upper aisle water tank for flushing. The underwater pump will not block and has a longer lifespan. The lower water tank is equipped with a decontamination hole to remove debris and garbage. According to customer needs, in areas where the weather is too cold, an electric heating system or a steam heating system can be installed on the water tank, and the heating temperature can be designed to maintain a certain temperature for flushing and wiping with water.
