Description

Technical Field

[0001] The utility model relates to the field of scale inhibitors, in particular to a scale inhibitor weighing device for boiler feeding. Background Art

[0002] Scale inhibitors are alkaline polymer materials that are soluble in water. They are solid highly concentrated water treatment agents that do not corrode boilers and plate heat exchanger equipment and can completely avoid the hazards of pickling. Pickling will cause waste of water resources such as running, bubbling, dripping, and leaking. Acidic descaling agents should not be added, as they will corrode the entire boiler wall thinner and thinner until the entire boiler is scrapped. For the normal use of boiler network equipment, scale inhibitors need to be added regularly for maintenance. However, scale inhibitors are generally added directly into the boiler for use. The different amounts of scale inhibitors added will produce different effects, and the amount of scale inhibitors added is not easy to automatically control;

[0003] Therefore, it is necessary to invent a scale inhibitor weighing device for boiler feeding. Utility Model Content
