Description

Technical Field

[0001] This utility model relates to the field of acid pickling and passivation treatment technology for storage tanks, and in particular to a high-efficiency acid pickling and passivation treatment device for storage tanks. Background Technology

[0002] The tank pickling and passivation treatment unit is a specialized piece of equipment used for pickling and passivating storage tanks. The main process includes three steps: pretreatment, pickling and passivation followed by rinsing, and post-treatment. Pretreatment primarily cleans the surface of the items to be pickled and passivated, removing various greases, welding spatter, weld scars, oxide scale, etc. Pickling and passivation can be performed separately or combined simultaneously. Post-treatment mainly protects the finished product, ensuring the tank surface remains uncontaminated and undamaged after pickling and passivation. The tank pickling and passivation treatment unit utilizes advanced chemical reaction principles, enabling rapid removal of contaminants from the tank surface and the formation of a dense oxide film in a short time, thus improving processing efficiency.

[0003] In practical applications, current tank pickling and passivation treatment equipment often involves applying pickling and passivation paste to the tank body and then manually smoothing it with cloths to form a passivation film. This manual application of the paste is extremely labor-intensive and inefficient, especially for large tanks. This is particularly true when the tank is large, with both diameter and length exceeding three meters, making manual operation even more difficult and significantly increasing time and labor costs.

[0004] During the application and smoothing process, manual operation may involve risks associated with working at heights and in confined spaces, which not only increases the difficulty of the operation but may also threaten the safety of the operators. Furthermore, controlling the uniformity and thickness of the application relies heavily on the operator's skills and experience, making it difficult to guarantee consistent results.
