Description

Technical Field

[0001] The utility model relates to the technical field of PAC dosing equipment, in particular to a precise dosing adjustment and control device for solid PAC. Background Art

[0002] Polyaluminium chloride (PAC) is also called basic aluminium chloride or hydroxyaluminium chloride. It or its hydrolysis products can be used to quickly precipitate the colloids in sewage or sludge, and large particles of precipitate can be easily separated. PAC reagent is a core unit of sewage treatment process, usually used as a coagulant, with high adsorption capacity, precipitation of sludge impurities, phosphorus removal and other functions.

[0003] In existing equipment, the dosing process often faces some challenges. For example, the utility model with patent number CN216377603U was originally designed to improve the efficiency and accuracy of drug delivery. This equipment is equipped with a vibrator on the side of the storage channel. In theory, the drugs can be densely arranged through vibration to ensure that the drugs can smoothly pass through the metering system into the sewage bucket. However, the actual situation is that the vibration process may cause the drugs to be stacked too closely together, forming agglomerations. Not only does it cause the agglomerated drugs to not be easily integrated into the water in time once they enter the sewage bucket due to changes in density and shape. It is also inconvenient for the metering box to control the amount of drugs, resulting in too much or too little drugs being put into the sewage. Utility Model Content
