Description

Technical Field

[0001] The utility model relates to the technical field of passivation tanks, in particular to a foam scraping plate for a passivation tank. Background Art

[0002] Passivation is a process that forms a dense and stable oxide film on the metal surface through chemical reaction, thereby reducing the activity of the metal and preventing further corrosion. This oxide film can effectively isolate the metal from direct contact with the external environment, reduce the dissolution rate of the metal, and put the metal in a passive state. The passivation tank is a special chemical treatment tank used to passivate the metal surface to enhance its corrosion resistance. In the passivation tank, as the passivation proceeds, impurities or oxide layers on the surface of the workpiece, accompanied by stirring or ventilation in the passivation tank, may react with the components in the pickling solution to produce gas and foam. These foams contain a large amount of impurities, which will have a negative impact on the subsequent passivation.

[0003] However, the existing passivation pool foam removal generally adopts the method of manual salvage using a filter. This manual salvage is time-consuming and laborious, and the foam removal efficiency is low. Utility Model Content

[0004] The utility model aims to provide a foam scraper for a passivation tank to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a foam scraper for a passivation tank, comprising: a passivation tank and an electric slide rail, electric slide rails are arranged on both sides of the top of the passivation tank, a slide plate is arranged between the tops of the electric slide rails, a negative pressure adsorption box is arranged on the top of the slide plate, a lifting guide column is arranged on one side of the negative pressure adsorption box, an adsorption cover is arranged on one side of the lifting guide column, a foam scraper is arranged on the bottom of the adsorption cover, a filter box cover is arranged on the top of the negative pressure adsorption box, negative pressure fans are arranged on both sides of the top of the filter box cover, a telescopic hose is arranged on the top of the adsorption cover, and one end of the telescopic hose extends to the inside of the negative pressure adsorption box.

[0006] Furthermore, a guide sleeve is provided on the outer wall of the negative pressure adsorption box at the connection position of the lifting guide column, and a suspended water tank is provided at the bottom end of the lifting guide column. The suspended water tank is suspended in the passivation tank by filling or draining water.

[0007] Furthermore, a water inlet valve is provided at one end of the negative pressure adsorption box, and a sewage discharge valve is provided at the other end of the negative pressure adsorption box.

[0008] Furthermore, the scraper plate is arranged at an angle, and the end of the scraper plate with a higher inclined surface is close to the negative pressure adsorption box.

[0009] Furthermore, when scraping off foam, the bottom end of the inclined surface of the foam scraping plate is located below the liquid surface of the passivation tank.

[0010] Furthermore, both ends of the electric slide rail are provided with limit blocks for preventing the slide plate from falling off, and the top of the lifting guide column is provided with a pier head for limiting.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model realizes that when the foam scraping plate is used in the passivation tank, the slide plate is driven by the electric slide rail to reciprocate on the passivation tank. When the foam needs to be scraped off, water is injected or discharged into the suspended water tank, so that the suspended water tank is in a suspended state in the passivation tank, and the lifting guide column is driven to rise and fall until the bottom end of the foam scraping plate is below the water surface and the top of the foam is below the top inner wall of the adsorption cover. At this time, the negative pressure fan is started to generate negative pressure wind force through the negative pressure fan, and the foam between the adsorption cover and the foam scraping plate is adsorbed into the negative pressure adsorption box through the telescopic hose. As the foam scraping plate follows the movement of the slide plate, the foam on the surface of the passivation tank is concentrated between the foam scraping plate and the adsorption cover for centralized adsorption and scraping. The whole device realizes automatic adsorption and scraping of foam through the cooperation of the electric slide rail and the negative pressure fan, and there is no need to manually remove the foam, which greatly improves the removal efficiency of the foam in the passivation tank, avoids the pollution of the impurities in the foam to the liquid in the passivation tank, and improves the passivation quality.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] See also Figure 1-Figure 4 The utility model provides a technical solution: a foam scraper for a passivation tank, comprising: a passivation tank 1 and an electric slide rail 2, electric slide rails 2 are arranged on both sides of the top of the passivation tank 1, a slide plate 3 is arranged between the tops of the electric slide rails 2, a negative pressure adsorption box 4 is arranged on the top of the slide plate 3, a lifting guide column 9 is arranged on one side of the negative pressure adsorption box 4, an adsorption cover 10 is arranged on one side of the lifting guide column 9, a foam scraper 11 is arranged on the bottom of the adsorption cover 10, a filter box cover 6 is arranged on the top of the negative pressure adsorption box 4, negative pressure fans 7 are arranged on both sides of the top of the filter box cover 6, a telescopic hose 8 is arranged on the top of the adsorption cover 10, and one end of the telescopic hose 8 extends to the inside of the negative pressure adsorption box 4. The bottom end of the scraper plate 11 is below the water surface, and the top of the foam is below the top inner wall of the adsorption hood 10. At this time, the negative pressure fan 7 is started to generate negative pressure wind force, and the foam between the adsorption hood 10 and the scraper plate 11 is adsorbed into the negative pressure adsorption box 4 through the telescopic hose 8. As the scraper plate 11 follows the movement of the slide plate 3, the foam on the surface of the passivation tank 1 is concentrated between the scraper plate 11 and the adsorption hood 10 for centralized adsorption and scraping.

[0020] The outer wall of the negative pressure adsorption box 4 is provided with a guide sleeve 14 at the connection part of the lifting guide column 9, and the bottom of the lifting guide column 9 is provided with a suspension water tank 12, which is suspended in the passivation tank 1 by filling or draining water. In this way, the height of the foam scraping plate 11 can be adjusted to avoid the foam scraping plate 11 being too high to collect foam, or the foam scraping plate 11 being too low, causing the foam to leak from the top of the adsorption cover 10.

[0021] A water inlet valve 5 is provided at one end of the negative pressure adsorption box 4, and a drain valve 13 is provided at the other end of the negative pressure adsorption box 4. After the foam scraping is completed, the foam impurities in the negative pressure adsorption box 4 need to be cleaned centrally. At this time, tap water is connected through the water inlet valve 5 to flush the negative pressure foam box 4, and the flushing water is discharged through the drain valve 13 to realize the flushing of the negative pressure adsorption box 4 and the filter box cover 6.

[0022] The foam scraping plate 11 is arranged at an angle, and the end with a higher slope of the foam scraping plate 11 is close to the negative pressure adsorption box 4. When scraping foam, the bottom end of the slope of the foam scraping plate 11 is located below the liquid surface of the passivation tank 1. It is convenient for the bottom end of the foam scraping plate 11 to extend below the liquid surface to collect the foam on the surface layer in a centralized manner to avoid omission.

[0023] Limiting blocks for preventing the slide plate 3 from falling off are arranged at both ends of the electric slide rail 2, and a pier head for limiting is arranged at the top of the lifting guide column 9.

[0024] When the foam scraper plate is used in the passivation tank, the electric slide rail 2 drives the slide plate 3 to reciprocate on the passivation tank 1. When the foam needs to be scraped off, water is added or drained into the suspension water tank 12, so that the suspension water tank 12 is suspended in the passivation tank 1, and the lifting guide column 9 is driven to rise and fall until the bottom end of the foam scraper plate 11 is below the water surface and the top of the foam is below the inner wall of the top of the adsorption cover 10. At this time, the negative pressure fan 7 is started, and the negative pressure wind force is generated by the negative pressure fan 7, and the adsorption cover 10 is sucked by the telescopic hose 8. The foam between the attached cover 10 and the scraper plate 11 is absorbed into the negative pressure adsorption box 4. As the scraper plate 11 follows the movement of the slide plate 3, the foam on the surface of the passivation tank 1 is concentrated between the scraper plate 11 and the adsorption cover 10 for centralized adsorption and scraping. The entire device realizes automatic adsorption and scraping of the foam through the cooperation of the electric slide rail 2 and the negative pressure fan 7. There is no need to manually remove the foam, which greatly improves the efficiency of removing the foam in the passivation tank, avoids the contamination of the liquid in the passivation tank by impurities in the foam, and improves the passivation quality.
