TECHNICAL FIELD

[0001] The utility model relates to the technical field of paint blending equipment, in particular to a paint blending container for solvent-based epoxy zinc-rich primer preparation. BACKGROUND

[0002] As a high-performance anticorrosive coating, solvent-based epoxy zinc-rich primer is widely used in heavy industrial fields such as steel structures, bridges, and ships. Its preparation process involves the precise mixing of various components, including solvents, epoxy resins, zinc powder, and other additives.

[0003] Traditional paint blending containers often have a single stirring mechanism, typically using one or a few sets of stirring paddles for mixing. While this mixing method can achieve a certain degree of raw material mixing, it is difficult to effectively prevent the clumping of solid components with high density and a tendency to agglomerate, such as zinc powder. This leads to uneven mixing and may even require extended mixing times to ensure the complete dispersion of solid components, which not only increases energy consumption but also reduces production efficiency.

[0015] (Three) beneficial effects

[0016] Compared with prior art, the utility model provides a kind of solvent type epoxy zinc-rich primer preparation is used to adjust paint container, with following beneficial effects:

[0017] This solvent-based epoxy zinc-rich primer mixing container, with its integrated mixing device and multiple annular feed pipes, allows for the simultaneous addition of various raw materials, avoiding the traditional method of adding materials one at a time. This not only improves work efficiency but also reduces potential contamination between different batches. The drive motor, which rotates the stirring rod on the shaft, provides initial stirring of the raw materials near the center of the mixing tank, enabling rapid material flow and helping to quickly break up agglomerates. This is particularly effective for denser solid components (such as zinc powder), preventing clumping and shortening the overall mixing time. The gear transmission mechanism allows the driven gear to rotate under the drive gear, achieving synchronous rotation at multiple levels. This multi-level, multi-angle stirring method ensures that all materials are fully involved in the mixing process, reducing the possibility of dead zones and residues, avoiding localized uneven concentrations, and guaranteeing consistent paint quality for each batch. This prevents product defects caused by uneven mixing or over-stirring, such as inconsistent color and texture, thereby improving the quality of the final product. Attached Figure Description
