Description

Technical Field

[0001] The utility model relates to the field of passivation tanks, in particular to a circulating passivation tank. Background Art

[0002] Passivation refers to the process in which a metal is oxidized by a strong oxidant or electrochemical method to make its surface inactive. It is a method of converting the metal surface into a state that is not easily oxidized, thereby slowing down the corrosion rate of the metal.

[0003] However, during the use of the passivation tank, metal devices are easily scratched by metal debris remaining in the passivator. In this regard, Chinese patent application No. 202011496626.8 discloses a metal casting surface passivation device and method, wherein the metal casting surface passivation device includes a passivation tank; a support plate is fixedly installed on the left side of the passivation tank; a filter box is fixedly installed on the left side of the passivation tank and above the support plate; a sieve plate is fixedly installed inside the filter box; a water pump is fixedly installed on the top of the support plate; the water inlet of the water pump is connected to a water suction pipe with one end passing through and extending into the passivation tank; the water outlet of the water pump is connected to a water injection pipe with one end connected to the filter box; the patent sets a filter box and a sieve plate in the filter box, and the passivator passes through the sieve plate in the filter box to screen out the metal debris in the passivator and re-enter the passivation tank, thereby preventing the metal from being scratched in the passivation tank.

[0004] However, when the passivation device provided by the patent is used, the sieve plate in the filter box cannot be cleaned automatically, which will cause the filter plate to be blocked after long-term use, thereby rendering the filter box ineffective; and the passivation agent in the passivation tank in the passivation device is exposed to the outside for a long time during use, making it easier for external impurities to infect the passivation agent.

[0043] The circulating passivation pool provided by Example 1 of the utility model has a first rotating shaft 111 on the top of the right end of the first collecting plate 11, and a second rotating shaft 121 on the top of the left end of the second collecting plate 12; the first rotating shaft 111 is arranged in the front-to-back direction, and the first rotating shaft 111 and the second rotating shaft 121 are parallel; the first driving component 13 is connected to the first rotating shaft 111, and the second driving component 14 is connected to the second rotating shaft 121; the circulating component 2 is arranged at the left and right ends of the passivation pool body 0, and the circulating component 2 connects the bottom of the passivation pool body 0 and the space above the first collecting plate 11, and the circulating component 2 transfers the passivation liquid at the bottom of the passivation pool body 0 to the top of the first collecting plate 11, and the first driving component 13 drives the first rotating shaft 111 to rotate counterclockwise, so that the first collecting plate 11 moves downward, one end of the first collecting plate 11 sinks, and the other end moves to make the elastic connecting member 16 bend, the first collecting plate 11, the elastic connecting member 16 and the second collecting plate 12 form a curved shape, and the first collecting plate 11 A gap is formed with the passivation tank body 0, and the passivation liquid flows along the curved portion formed by the first collecting plate 11, the elastic connecting member 16 and the second collecting plate 12, and flows to the gap formed by the first collecting plate 11 and the passivation tank body 0, and the passivation liquid is returned to the passivation tank body 0 through the gap to continue the passivation reaction with the metal device; or the second driving assembly 14 drives the second rotating shaft 121 to rotate clockwise, so that the second collecting plate 12 moves downward, the elastic connecting member 16 bends, and the second collecting plate 12 and the passivation tank body 0 form a gap, and the passivation liquid flows to the gap formed by the second collecting plate 12 and the passivation tank body 0, and the passivation liquid is returned to the passivation tank body 0 through the gap to continue the passivation reaction with the metal device; by selectively opening the first collecting plate 11 or the second collecting plate 12, the passivation liquid can reach different positions in the passivation tank body 0, and the continuous circulation of the passivation liquid can mix the passivation liquid around the metal device, prevent the pH value of the passivation liquid around the metal device from decreasing, thereby avoiding poor passivation effect of the metal device.

[0045] The circulating passivation pool provided by Example 1 of the utility model includes a vertical moving component 15. When the first collecting plate 11 and the second collecting plate 12 have recovered the metal debris in the passivation liquid, the first collecting plate 11 and the second collecting plate 12 are restored to a horizontal placement state, and the first collecting plate 11 and the second collecting plate 12 are lifted by the vertical moving component 15 so that the first collecting plate 11 and the second collecting plate 12 are flush with the pool mouth of the passivation pool body 0, so that the metal debris collected by the first collecting plate 11 and the second collecting plate 12 can be cleaned out of the passivation pool body 0 by the cleaning component 3; it also includes a cleaning component 3, which is arranged on the top of the passivation pool body 0.

[0046] In the circulating passivation pool provided in Example 1 of the utility model, preferably, the first drive component 13 and the second drive component 14 are servo motors; when it is necessary to discharge the passivation liquid transmitted to the top of the first collecting plate 11 by the circulating component 2, the output shaft of the first drive component 13 is fixed to the first rotating shaft 111, and the axis of the output shaft of the first drive component 13 is located on the same straight line as the axis of the first rotating shaft 111; the output shaft of the second drive component 14 is fixed to the second rotating shaft 121, and the axis of the output shaft of the second drive component 14 is located on the same straight line as the axis of the second rotating shaft 121. At this time, the first drive component 13 controls the first rotating shaft 111 to rotate counterclockwise with the axis of the first rotating shaft 111 as the center, and the first collecting plate 11 is located on the left side of the second collecting plate 12, and is aligned with the first rotating shaft 11 After the first collecting plate 11 fixed to the first collecting plate 1 rotates counterclockwise, the first collecting plate 11 and the passivation tank body 0 form a flow gap, so that the passivation liquid stored on the upper part of the collecting plate is discharged into the bottom of the passivation tank body 0 along the tilting direction of the first collecting plate 11; or, the second driving assembly 14 controls the second rotating shaft 121 to rotate clockwise with the axis of the second rotating shaft 121 as the center, and the second collecting plate 12 is located on the right side of the first collecting plate 11. After the second collecting plate 12 fixed to the second rotating shaft 121 rotates clockwise, the second collecting plate 12 and the passivation tank body 0 form a flow gap, so that the passivation liquid stored on the upper part of the collecting plate is discharged into the bottom of the passivation tank body 0 along the tilting direction of the second collecting plate 12. The above method is used to control the discharge direction of the passivation liquid;

[0047] The circulation component 2 includes two transmission pumps 21; the two transmission pumps 21 are arranged on the left and right sides of the passivation tank body 0, the water inlet of the transmission pump 21 is connected to the bottom space of the passivation tank body 0, and the water outlet of the transmission pump 21 is connected to the upper space of the first collecting plate 11.
