Description

TECHNICAL FIELD

[0001] The utility model relates to the field of aluminium chloride production, especially to a dilution and taking device of polyaluminium chloride. BACKGROUND

[0002] Polyaluminium chloride is a high-efficiency flocculant. Compared with traditional aluminum salts, polyaluminium chloride has lower dosage, relatively economical cost, strong pH adaptability and high safety. When used, polyaluminium chloride usually needs to be diluted with tap water or deionized water, which is easier to dissolve after dilution, thereby increasing its effectiveness. The dosage of polyaluminium chloride needs to be strictly and accurately controlled during dilution, and the dosage of both polyaluminium chloride and dilution water needs to be controlled.

[0003] The existing polyaluminium chloride is diluted by manual pouring of water, which is prone to errors, resulting in inaccurate dilution ratio. It is difficult to accurately control the content of polyaluminium chloride and water by manual pouring, which leads to too high or too low concentration of the diluted polyaluminium chloride solution. If the concentration is too high, it may cause excessive flocculation or precipitation; if the concentration is too low, it may not be able to effectively remove pollutants. At the same time, during the operation process, chemicals may be contacted, increasing the safety risk and requiring more human input, thereby increasing labor costs. Therefore, we propose a dilution and taking device of polyaluminium chloride to solve the above problems. SUMMARY
