Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a reaction kettle for preparing zinc plating additives. Background Art

[0002] Galvanizing is an anti-corrosion method that prevents corrosion by forming a protective layer of zinc on the metal surface. In the preparation process of galvanizing additives, a reactor can be used for reaction mixing. In order to ensure the progress of the reaction, produce the desired reaction products, and maintain the uniformity and efficiency of the reaction, it is necessary to control the reaction conditions such as temperature, pressure and stirring speed. The most direct method is to increase the stirring speed. A higher stirring speed can more effectively mix the reactants and increase the contact between them, thereby promoting more reactions.

[0003] In the prior art, for example, publication number CN218834334U discloses a reactor for preparing zinc plating additives. The reactor drives a stirring rod to rotate through a driving motor, and can quickly stir the solution. Then, through the coordinated arrangement of a filter box, a mounting frame, a heavy metal adsorption layer, an organic adsorption layer, an activated carbon filler layer, and a drain port, the heavy metals and impurities in the solution can be quickly and effectively filtered, thereby avoiding the use of other filtering devices, shortening the processing time, improving the preparation efficiency, and ensuring the quality of the additive.

[0004] During use of the above-mentioned reactor, the agitator can cover a small range inside the reaction container, which is prone to local dead zones, resulting in uneven mixing of reactants in some areas. In addition, after use, reactants and other dirt remain on the inner wall of the reactor, which is not easy to clean. Utility Model Content

Four groups of array-distributed pads 3 are fixedly connected to the bottom surface of the reactor body 1. The four groups of pads 3 provide support and stability for the reactor body 1 to ensure that the reactor body 1 is placed stably.

[0033] Reference Figure 2 - Figure 3 The reactor body 1 is provided with a stirring assembly 4, which is used to stir the reactants inside the reactor body 1, thereby accelerating the reaction rate of the reactants, and can change the stirring range to avoid the situation where the reactants are mixed unevenly in some areas. The stirring assembly 4 includes a rotating shaft 41, one end of which is rotatably connected to the inner wall of the reactor body 1, and the other end of the rotating shaft 41 penetrates and is rotatably connected to the top of the reactor body 1.
