Abstract
The utility model discloses a device for moisturizing strip steel in an electroplating tank through a gravity method. The device comprises a circulating tank and four spraying pipes, wherein a water inlet pipe and a water outlet pipe are respectively arranged on the circulating tank; a booster pump and a corresponding control valve are additionally arranged on a pipeline of the water outlet pipe; the four spraying pipes are respectively located above a strip steel downlink positioning roller, a strip steel uplink drying roller, a strip steel uplink drying roller and a pressing roller of a conductive roller; a plurality of nozzles are arranged on the spraying pipes and are uniformly distributed in the width direction of the strip steel; and each spraying pipe is connected with outlet pipelines of the booster pump on the water outlet pipeline of the circulating tank through connecting pipes, and valves are arranged on the respective connecting pipes. When the device is adopted, surface moisturizing capacity of the strip steel discharged out of the electroplating tank can be effectively improved, uniformity of the surface moisturization of the strip steel can be guaranteed, and zinc sulfate remained on the surface of the strip steel can be obviously reduced, therefore, the defects of electroplating spots due to the gravitational electroplating process is reduced, the surface quality of the strip steel is obviously improved, and the stable operation of a unit is guaranteed.
Description
Technical field
The utility model relates to electroplating device, and particularly gravity method is electroplated troughed belt steel moisturizing device.
Background technology
2030 cold rolling electroplating zinc unit plating tanks adopt vertical gravity method electroplating technology, as shown in Figure 1, each trough is equipped with a conductive rollers 10, sinking roller 20, four anode boxs 30, descending registration roller 40, a pair of squeezing roller 50 and a conductive rollers pressure roller 60.
The characteristics of gravity method electroplating technology before the band steel goes out plating tank and enters next coating bath, have long section strip steel to be exposed to outside the plating bath, also promptly among air.Electro-galvanizing liquid is solution of zinc sulfate, directly contacts with conductive rollers after the band steel goes out coating bath, if the residual zinc sulfate of belt steel surface, then the conductive rollers surface also can produce zinc in electroplating process, and fragile conductive rollers surface directly influences strip surface quality.If the moistening degree of belt steel surface was inhomogeneous after the band steel went out coating bath, residual zinc sulfate is inhomogeneous, because of the band steel is exposed to mass defects such as also easily causing electroplating mottling among the air.
At the electro-galvanizing unit thermal load initial stage, just inhomogeneous because be with steel to go out the moistening degree in coating bath rear surface, residual zinc sulfate has caused mass defects such as plating mottling, has directly influenced the ordinary production operation of unit.
When going out the coating bath anode box, the band steel designed a pair of squeezing roller and a conductive rollers pressure roller, design has two jet pipe humid zone steel, promptly respectively designed a jet pipe 70,80 in band steel upper and lower surface, band steel upper surface jet pipe 70 is positioned at conductive rollers pressure roller 60 tops, band steel lower surface jet pipe 80 is above squeezing roller 50, jet pipe supplies water does not have independent waterworks, shared with other waterworks of unit, as shown in Figure 1.
But this design practical effect is bad, and particular problem mainly contains: jet pipe is arranged unreasonable, a little less than the moisture-retaining capacity, is difficult to reach the effect that the band steel is preserved moisture; The influence that moisturizing device is ordered by other user of unit waterworks is difficult to guarantee to spray effect, and is bad during fashion, is difficult to reach the ideal effect.Thereby be difficult to effectively to prevent to electroplate the generation of defectives such as mottling, the final product quality and the ordinary production of unit caused very big influence.
Summary of the invention
The purpose of this utility model is to design a kind of gravity method and electroplates troughed belt steel moisturizing device; can effectively improve the band steel goes out the moisture-retaining capacity of plating tank belt steel surface and guarantees the homogeneity that belt steel surface is moistening; significantly reduce the residual zinc sulfate of belt steel surface; thereby effectively reduce the gravity method electroplating technology and electroplate the mottling defective; significantly improve strip surface quality, guarantee the set steady operation.
For achieving the above object, the technical solution of the utility model is:
Gravity method coating bath band steel moisturizing device, it comprises, circulation groove is respectively equipped with water inlet pipe, rising pipe on it; Establish topping-up pump and control corresponding valve on the pipeline of rising pipe; Four jet pipes lay respectively at the descending registration roller of band steel top, band steel lower face side; The up squeezing roller of band steel top, band steel upper surface side; The up squeezing roller of band steel top, band steel lower face side and conductive rollers pressure roller top, band steel upper surface side; Several nozzles are arranged on the jet pipe, uniform along the strip width direction; Each jet pipe is connected by the export pipeline of topping-up pump on pipe connecting and the described circulation groove rising pipe pipeline respectively, and each pipe connecting is provided with valve.
Further, described nozzle spout is fan-shaped, and jet angle is greater than 90 °.
Establish strainer on the pipeline of described circulation groove rising pipe, remove the impurity in the solution, guarantee the degree of cleaning of solution, avoid the nozzle on the impurity obstruction jet pipe.
Described control valve is a magnetic valve.
Described pipe connecting is a flexible pipe.
Replenish pure water by control valve control to circulation groove, the topping-up pump supercharging on main feed flow loop is to the jet pipe feed flow; The upper and lower surface of nozzle spray band steel by every jet pipe.Every group of jet pipe upper spray nozzle, uniform along the strip width direction, nozzle be fan-shaped spray, guarantee that sprayed solution can cover whole strip width.
The beneficial effects of the utility model
The utility model can effectively improve the band steel and go out the moisture-retaining capacity of plating tank belt steel surface and guarantee the homogeneity that belt steel surface is moistening; significantly reduce the residual zinc sulfate of belt steel surface; thereby effectively reduce the gravity method electroplating technology and electroplate the mottling defective; significantly improve strip surface quality, guarantee the set steady operation.
