Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a water washing nozzle for washing an object to be plated with water in a continuous plating device that handles a strip-shaped object to be plated.

"Conventional technology" Conventional plating equipment uses, for example,
As disclosed in the above publication, upright pipes are provided facing each other through the passage portion of the belt-shaped object to be plated, and on the opposite sides of each pipe, there is a direction in which the object to be plated passes or vice versa. A spraying device has been proposed in which a slit-shaped water spout is formed and the treatment liquid is sprayed onto the object to be plated from the spout.

"Problems to be solved by the invention" When the injection device disclosed in the above patent publication is used, for example, for washing a continuous plating device, the fifth problem is
As shown in the figure, cleaning water is sprayed directly onto the object a to be plated from a vertical slit-shaped fountain 60 formed in the pipe 6. When water e comes out from the fountain 60, it gradually spreads and hits the object to be plated, so the range of water scattering (particularly in the direction of travel) after colliding with the object to be plated increases accordingly, making it easier to install a cleaning room. Requires a lot of space.

Of course, the scattering range of this water depends on the water pressure, the inclination angle of the water fountain 60, the size of the water fountain 60, etc., but these conditions should be adjusted to be most suitable for cleaning the object to be plated and the processing solution. Even if it is designed, the spread of the fountain from the fountain mouth 60 cannot be ignored.

Continuous plating equipment has approximately 40 to 60 processes, and half to two-thirds of these are water washing processes, so even if each washing chamber is slightly expanded, the difference in the overall equipment is several tens of times larger. Therefore, the overall space efficiency is greatly reduced.

An object of the present invention is to provide a washing nozzle for a continuous plating device that can further reduce the spread of the fountain from the fountain opening.

"Means for Solving the Problems" In order to achieve the above-mentioned purpose, the water washing nozzle according to the present invention connects a bag-shaped pipe into which washing water is supplied at a predetermined pressure to a passage area for a band-shaped object to be plated. pipes facing each other and along the width direction of the object to be plated, with slit-shaped water fountains formed along the longitudinal direction on opposite sides of the pipes, and directly in front of each water fountain. An inclined guide wall is provided on the outer wall of the tube and is inclined at a predetermined angle in the passing direction of the object to be plated or in the opposite direction.

``Operation'' Since the water washing nozzle according to the present invention is constructed as described above, the water jetted from the water fountain hits the inclined guide wall, is changed direction by the inclined guide wall, and hits the side surface of the object to be plated.

When guided by the inclined guide wall, the water is formed into a thin film, so it gradually spreads as it approaches the object to be plowed, but the spread is much narrower than when it hits the object directly from the fountain. .

"Embodiment" A preferred embodiment of the water washing nozzle according to the present invention will be described with reference to FIGS. 1 to 4.

The washing nozzle 3 is connected to a washing water supply pipe (not shown) via a pipe joint 2 protruding from the bottom of the washing chamber 1.

The strip-shaped object a to be plated is kept upright in the width direction by a guide 4 provided on a partition wall between the cleaning chamber 1 and another processing tank 5 in the previous process, and is vertically moved through the washing nozzle 3 in the cleaning chamber 1. passes through the passage part d of
It is washed with water sprayed by the washing nozzle 3 and transferred to the next treatment step.

The water washing nozzle 3 of this embodiment is shown in FIGS. 2 and 3.
As shown in the figure, bag-shaped pipes 3 are arranged so as to face each other almost vertically across a passage d for the material to be plated.
0 and 30, each tube 30 joins in a Y-shape at the base end, and a socket portion 31 is formed at the base end to which the pipe joint 2 is connected.

The water washing nozzle 3 of this embodiment has a passage part d for the object to be plated (a) formed in the center, and two divided blocks each having a Y-shaped groove corresponding to half of the pipe 30 formed on one side. It is constructed by joining the Y-shaped grooves so that they match, and this construction facilitates maintenance management such as replacing the nozzle in the event of clogging or other failure.

Slit-shaped water fountains 32 are formed intermittently along the longitudinal direction on opposing sides of each of the pipes 30, and immediately before each water fountain 32, a water fountain 32 is formed.
2, slope guide walls 33 are formed that extend at a constant inclination in the direction of passage of the object to be plated from the rear edge in the direction of passage of the object to be plated in the direction of passage of the object to be plated in each pipe 30. A waterproof cover 34 is provided at the front.

The inclination angle θ (FIG. 3) of the inclined guide wall 33 is:
Although it depends on the distance between the bag-shaped tubes 30, it is preferable to set the distance in the range of about 45 to 60 degrees as a rough guide.

According to the water washing nozzle 3 of this embodiment, as shown in FIG. It is guided in an inclined state in the passing direction and hits the side surface of the object to be plated a.

When the cleaning water e is guided as described above by the inclined guide wall 33, it is formed into a thin film and hits the object to be plated, so the spread is much smaller, the water scattering range is narrower, and it is easier to clean. Splashing can be prevented by waterproof cover 34 and other waterproof means, and cleaning room 1
The installation space can be made smaller.

In the embodiment described above, the inclined guide wall 33 is inclined in the passing direction of the object to be plated a, but it can also be made to be inclined in the opposite direction to the passing direction.

"Effect of the invention" The washing nozzle according to the invention has a slit-shaped water spout provided on opposite sides of the pipes facing each other through the passing part of the object to be plated, and an inclined guide wall provided just in front of this water spout. Therefore, when the fountain from the fountain is guided in the inclined direction by this inclined guide wall, the water is formed into a thin film and the spread of the water becomes very small.If other conditions such as water pressure are the same, the conventional The scattering range of cleaning water can be made narrower than the device.

Therefore, the individual cleaning chambers of the continuous plating device can be made smaller to improve the space efficiency of the entire device.
