The compensation plate 303b is arranged on the shielding plate 303a, and the compensation plate 303b is arranged on the lower side of the shielding plate 303a, and in the dissolution The compensation plates 303b are movable and connected in the dissolution chamber 102b. There are two compensation plates 303b for compensating for the portion extending from the shielding plate 303a, further preventing oxalic acid powder from entering the portion extending from the shielding plate 303a and affecting the resetting of the shielding plate 303a. The extension plate 303c is arranged on the compensation plate 303b, and the extension plate 303c is fixedly connected to the compensation plate 303b. The extension plate 303c is arranged on both sides of the compensation plate 303b and moves in the groove opened in the dissolution chamber 102b. The spring 303d is arranged on the extension plate 303c, and the spring 303d is fixedly connected to the extension plate 303c. As the shielding plate 303a moves upward, the compensation plate 303b moves to the position of the shielding plate 303a under the action of the spring 303d, thereby completing the work of filling the position of the shielding plate 303a.

[0054] The remaining structure is the same as that of Example 2.

[0055] Operation steps: by replenishing the electrolyte in the reaction chamber 101a, after replenishment, the pushing block 301a on the rotating shaft 201b can push the lifting block 301b to move up with the synchronization frame 301d, so that the pushing plate 302a on the synchronization frame 301d pushes the shielding plate 303a to move up with the inflow plate 302c, so that part of the oxalic acid powder in the accumulation chamber 102c enters the water tank 102d through the inflow groove 302d of the inflow plate 302c, and dissolves with the water entering from the pure water pipe 102e. When the pH detector 101c in the water tank 102d shows that the pH value of the reaction chamber 101a meets the requirements, it can wait to enter the reaction chamber 101a. The whole device solves the problem that the addition of electrolyte solutes mainly depends on manual direct addition of solutes, ensures the amount of solute added and the uniformity of dissolution, and prevents the problem of uneven electric field caused by uneven electrolyte concentration, thereby causing uneven oxide film. The whole operation saves time and effort and is safer.

[0056] Example 4

[0057] As a fourth embodiment of the present invention, a method for adding oxalic acid for anodization is provided, comprising the following steps:

[0058] S1, placing the aluminum product in the reaction chamber 101a of the process part 101 to perform an anodic oxidation reaction;

[0059] S2. When the consumption of electrolyte drops to a certain level, the alarm control device is triggered to start;

[0060] S3, adding electrolyte with the same pH value to the reaction chamber 101a of the process element 101 so that the anodic oxidation reaction continues;

[0061] S4, start the motor 201a to open the water tank 102d to transport the dissolved electrolyte to the reaction chamber 101a;

[0062] S5. After the electrolyte is delivered, some oxalic acid in the accumulation chamber 102c is taken out for dissolution again, and the pH value is controlled to wait for the next delivery.

[0063] The whole process reduces manual intervention and improves the accuracy of chemical reactions. The present invention helps to reduce production costs. The automated system reduces dependence on highly skilled operators, while improving the utilization of raw materials and reducing waste.
