[0002] A metal surface treatment agent generally refers to a chemical agent for various treatments of the metal surface. Metal surface treatment includes substrate pretreatment such as degreasing, rust removal, phosphating, and rust prevention, which prepares for metal coating technology and metal protection technology. The quality of substrate pretreatment has a great impact on the subsequent coating preparation and the use of the metal.

[0003] Currently, when preparing an environmentally friendly metal surface treatment agent, a preparation barrel for mixing and reacting is required. Moreover, in order to improve the preparation quality of the treatment agent, the preparation barrel needs to be cleaned regularly. However, the existing cleaning work of the preparation barrel is generally carried out manually, which is rather troublesome during the operation process. At the same time, the prepared barrel after cleaning needs to be naturally dried, thus affecting the subsequent preparation work efficiency of the treatment agent.

[0004] In order to solve the above problems, this application provides an environmentally friendly metal surface treatment agent and a preparation method thereof. Summary of the Invention

[0047] The implementation principle of this application includes the following steps:

[0048] S1: While unscrewing and removing each locking nut 20, vertically extract the cover plate 2 through the handle ring 18, and drive the lower end of the rotating shaft 4 to disengage from the inside of the preparation barrel 1. Then, through the removal of each fixing bolt 13, the disassembly operation of the two U-shaped frames 11 and the cleaning brushes 14 thereon is realized. During this process, each insertion rod 12 is separated from the insertion hole 10. After that, while resetting the cover plate 2 to the top of the preparation barrel 1, reinstall and reset each locking nut 20;

[0049] S2: While putting each proportioned raw material of the environment-friendly metal surface treatment agent into the preparation barrel 1 through the feeding port 17, start the driving motor 3 and drive the rotating shaft 4 and each stirring paddle 9 to rotate, so as to realize the full and uniform mixing of each proportioned raw material.

After the preparation is completed, it can be discharged and collected through the discharge pipe 15 and the first solenoid valve 16;

[0050] S3: When it is necessary to clean the inner wall of the preparation barrel 1, after the two U-shaped frames 11 and the cleaning brushes 14 are reset and installed, the solenoid valve 16 is opened and the solenoid valve 23 remains closed. Then, while connecting a water pipe to the top of the water guide pipe 8, the drive motor 3 is started. During this process, the cleaning water source flows into the inside of the flow ring 5 and is then sprayed onto the inner wall of the preparation barrel 1 through each nozzle 6. The rotating shaft 4 indirectly drives the two U-shaped frames 11 and the cleaning brushes 14 to rotate during the rotation process, thereby completing the cleaning of the inner wall of the preparation barrel 1. The sewage during the cleaning process is discharged through the discharge pipe 15.

[0051] S4: After the cleaning of the inner wall of the preparation barrel 1 is completed, the solenoid valve 16 is closed and the solenoid valve 23 is opened. The movable cover on the feed inlet 17 is opened. Then, while the exhaust fan 27 and the electric heating tube 29 are simultaneously turned on, hot source gas is continuously poured into the inside of the preparation barrel 1 indirectly through the upper side of the discharge pipe 15. With the cooperation of the discharge function of the dried moisture through the feed inlet 17, the rapid drying of the inner wall of the preparation barrel 1 after cleaning is realized, thus avoiding affecting the preparation efficiency of the subsequent treatment agent. During the drying process, the gas entering the inside of the connecting cylinder 25 is filtered by the dust-proof net 26 to prevent pollution of the inside of the preparation barrel 1.

[0052] The above are all preferred embodiments of this application, and the protection scope of this application is not limited accordingly.

10. A method for preparing an environmentally friendly metal surface treatment agent, characterized in that: The following steps are involved: S1: While each locking nut (20) is being screwed off, the cover plate (2) is vertically extracted by the ring (18), and the lower end of the rotating shaft (4) is driven to be separated from the interior of the preparation barrel (1), and then the U-shaped frames (11) on both sides and the cleaning brushes (14) thereon are removed by disassembling each fixing bolt (13), and each insertion rod (12) is separated from the insertion hole (10) during the process, and then the cover plate (2) is reset to the top of the preparation barrel (1), and each locking nut (20) is reinstalled and reset; S2: while feeding the various proportions of raw materials of the environmentally friendly metal surface treatment agent into the preparation barrel (1) through the feed port (17), the drive motor (3) is started to drive the rotating shaft (4) and each stirring paddle (9) to rotate, so as to achieve full and uniform mixing of the various proportions of raw materials, and during the mixing process, the pH value range of the prepared treatment agent can be adjusted and controlled by detecting with a pH meter and adding water raw materials for dilution. After the preparation is completed, the treatment agent can be discharged and collected through the discharge pipe (15) and the electromagnetic valve 1 (16); S3: When it is necessary to clean the inner wall of the preparation barrel (1), the two U-shaped frames (11) and the cleaning brush (14) must be reset and installed first, so that the first solenoid valve (16) is in an open state and the second solenoid valve (23) is still in a closed state, and then the top of the water pipe (8) is connected to the water pipe, and the drive motor (3) is started. During this process, the cleaning water source flows into the inside of the circulation ring (5) and is then sprayed onto the inner wall of the preparation barrel (1) through each nozzle (6). During the rotation of the rotating shaft (4), the U-shaped frames (11) and the cleaning brush (14) on both sides are indirectly driven to rotate, thereby completing the cleaning of the inner wall of the preparation barrel (1), and the sewage during the cleaning process is discharged through the discharge pipe (15); S4: After the inner wall of the preparation barrel (1) is cleaned, the solenoid valve 1 (16) is in a closed state and the solenoid valve 2 (23) is in an open state, so that the movable cover on the feed port (17) is in an open state, and then the exhaust fan (27) and the electric heating tube (29) are simultaneously turned on, and the heat source gas is continuously injected into the interior of the preparation barrel (1) indirectly through the upper side of the discharge pipe (15), and the feed port (17) cooperates with the discharge of dried water to achieve rapid drying of the inner wall of the preparation barrel (1) after cleaning, thereby avoiding affecting the preparation efficiency of the subsequent treatment agent. During the drying process, the gas entering the interior of the connecting tube (25) is filtered by the dustproof net (26) to prevent contamination of the interior of the preparation barrel (1).
