Description

Technical Field

[0001] The utility model relates to the technical field of paint packaging, in particular to a large paint packaging device which is equipped with a stirrer and has a stirring paddle that is easily detachable. Background Art

[0002] As the scale of industry grows, the scale of anti-corrosion work has also increased. Currently, domestic shipyards and steel structure plants of a certain size perform anti-corrosion work on tens or even hundreds of thousands of square meters daily, using thousands or even tens of thousands of liters of paint. Traditional paint packaging comes in 20L containers. Most paints are two-component, requiring each container to be mixed and stirred sequentially, with each container taking anywhere from 1 to 5 minutes to mix. Mixing paint requires dedicated personnel to pour and stir, incurring significant labor costs. Furthermore, a small amount of paint residue remains in each paint bucket, leading to paint waste. Furthermore, since this residual paint is considered hazardous waste, the paint buckets cannot be recycled due to contamination and require specialized recycling, which is difficult and costly. For these reasons, the demand for large paint packaging is growing.

[0003] Currently, the design of large paint packaging lacks standardization and is not perfect. Most large packages do not have integrated agitators. For example, the large paint packaging device disclosed in patent document with publication number CN205076299U requires an agitator to be installed on-site. The agitator is heavy and requires the cooperation of multiple people, and even requires the assistance of a forklift for installation. Some large paint packaging with integrated agitators also has the disadvantages of being too complex and heavy, and the agitator blades are difficult to disassemble, making it inconvenient to clean the paint bucket. For example, patent document with publication number CN117022422A discloses a large paint packaging IBC transport device with pneumatic stirring function. Although it has an integrated agitator, the agitator structure is too complex and heavy, the manufacturing cost is high, and the agitator blades cannot be disassembled, making it inconvenient to clean the inside of the barrel.
