Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of aluminium hydroxide production, especially to an aluminium hydroxide washing device. BACKGROUND

[0002] Aluminium hydroxide is an inorganic substance, which is the hydroxide of aluminium. It can react with acid to generate salt and water, and it can also react with strong alkali to generate salt and water. Therefore, it is an amphoteric hydroxide. Due to its certain acidity, it can also be called aluminate. However, when it actually reacts with alkali, it generates tetrahydroxy aluminate. Therefore, it is usually regarded as monohydrate meta-aluminate, which is divided into industrial grade and pharmaceutical grade according to its use.

[0003] In the production process of aluminium hydroxide, the prepared aluminium hydroxide precipitate usually needs to be washed to fully wash and flush away other components contained in the aluminium hydroxide precipitate, so as to ensure that aluminium hydroxide with high purity can be obtained.

[0004] The Chinese utility model patent with the patent application number CN202322942250.4 records a kind of aluminium hydroxide filtering and washing device. The filter screen barrel, annular water baffle, gear chuck and paddle are arranged. The aluminium hydroxide and washing liquid in the filter screen barrel are continuously stirred by the paddle driven by motor. The aluminium hydroxide does not precipitate too fast, and the screen hole on the filter screen barrel is not blocked, so that impurities exist in the aluminium hydroxide. By continuous stirring, the aluminium hydroxide and washing liquid can be fully mixed, and the quality of the prepared aluminium hydroxide is improved. However, the filter screen barrel in the above-mentioned washing device is vertically placed, and the aluminium hydroxide is in a precipitated state during washing. Therefore, the aluminium hydroxide will fall to the bottom of the filter screen barrel during washing, so that the cleaning agent cannot fully contact with the aluminium hydroxide after the aluminium hydroxide falls to the bottom of the barrel, which reduces the washing effect. The impurities in the aluminium hydroxide cannot be completely removed, which reduces the washing effect and quality. UTILITY MODEL CONTENTS
