Description

Technical Field

[0002] Currently, phosphoric acid storage tanks generally feature a cylindrical, vertical, flat-bottom structure, manufactured from high-quality, acid- and alkali-resistant polyethylene using a single-shot rotational molding process. The tanks are smooth inside and out and are resistant to acid, alkali, impact, high temperatures, freezing, UV rays, and aging.

[0003] Phosphoric acid storage tanks used by compound fertilizer manufacturers are large and can hold a large amount of phosphoric acid. However, after storing phosphoric acid in the tanks for a period of time, precipitated sediment forms on the tank walls, forming scale. Over time, this scale builds up inside the tank walls. Under the influence of gravity and external vibrations, the scale layer can collapse locally on the tank walls.

[0004] At present, the only way to clean the scale on the tank wall is manual cleaning. Manual cleaning requires the use of a crane to dig and clean the scale from top to bottom. The excavation and cleaning process sometimes causes irreversible damage to the tank lining, which not only leads to a significant increase in maintenance costs, but also poses a safety and environmental hazard of tank perforation.

[0005] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content
