Description

Technical Field

[0001] The utility model relates to the technical field of impurity removal, in particular to liquid calcium hydroxide impurity removal equipment. Background Art

[0002] Calcium hydroxide is commonly known as slaked lime. After adding water and standing, it will form two layers, the upper aqueous solution is called clear lime water, and the lower suspension is called lime milk or lime slurry. The lower turbid liquid lime milk is a building material. Calcium hydroxide is widely used in various industrial fields. It is generated by the reaction of quicklime and water, and its saturated aqueous solution is called lime water. It is a commonly used building material and is also used as a fungicide and chemical raw material. Due to the actual production situation, quicklime reacts with water to produce slaked lime. However, because the quicklime is impure, there are often many impurities such as stones remaining in the slaked lime, which are of different sizes and have the same color as slaked lime. It is difficult to remove, which seriously affects the actual quality of use. Therefore, an impurity removal device is needed for impurity removal.

[0003] The existing liquid calcium hydroxide impurity removal equipment cannot completely remove impurities, and the impurity removal speed is slow, which increases the time cost. The screen is not easy to clean, resulting in clogging of the screen holes, low impurity removal efficiency, and poor effect, which affects the actual application effect. Therefore, we propose a liquid calcium hydroxide impurity removal equipment. Utility Model Content
