Description

Technical Field

[0001] This utility model relates to the field of PAM dosing technology, specifically to a PAM dosing device. Background Technology

[0002] Polyacrylamide, abbreviated as PAM, is a linear polymer that is also classified as anionic (HPAM), cationic (CPAM), and nonionic (NPAM). It is one of the most widely used water-soluble polymers. Polyacrylamide and its derivatives can be used as effective flocculants, thickeners, paper strengthening agents, and drag-reducing agents for liquids. They are widely used in water treatment, papermaking, petroleum, coal, mining and metallurgy, geology, light textile, construction and other industrial sectors.

[0003] The main raw material for PAM is acrylamide monomer (AM), along with other modifiers, such as acrylic acid, that can be used to prepare anionic, cationic, or nonionic products. In a mixing tank, the raw materials are accurately weighed and mixed according to the designed formula. Acrylamide and other monomers are dissolved in water, and appropriate initiators (such as persulfates, azo compounds, etc.) and additives to adjust molecular weight and charge properties are added. Reaction conditions need to be precisely controlled, including temperature, pressure, stirring speed, and reaction time. Continuous or batch polymerization reactions are typically carried out at a specific temperature.

[0004] In the production process of PAM, raw materials need to be accurately weighed and mixed according to the designed formula. When adding raw materials during production, manual weighing is usually used. Weighing multiple raw materials and adding them is relatively slow and affects the production efficiency of PAM.
