AI Technical Summary
In the existing polyaluminum chloride production process, the sludge deposited at the bottom is difficult to be effectively suspended and removed, especially the sludge with a higher specific gravity or smaller particle size, which affects product quality and equipment life.
The system uses a ring-shaped water pipe and nozzles to spray water, which is combined with scrapers that squeeze and rotate the inner wall of the sludge removal chamber. The push rod is driven by the squeezing rod and hydraulic rod. The air pressure difference causes the scraper to scrape up the sludge close to the inner wall and suspend it through the water flow. Combined with the mixing blades, the sludge is prevented from caking.
It effectively suspends and removes bottom sludge, reduces equipment wear, extends service life, and improves product quality.

TECHNICAL FIELD
[0001] The utility model relates to the production technology field of polyaluminium chloride, especially relates to a mud removing device for polyaluminium chloride production. BACKGROUND
[0002] In the production process of polyaluminium chloride, mud removal is an indispensable key process. If the soil impurities in the raw materials are not effectively removed, it will seriously affect the product quality and reduce the flocculation effect and purity of polyaluminium chloride. Therefore, a mud removing device is needed.
[0003] In the patent with the publication number CN217614178U, a mud removing device for polyaluminium chloride production is disclosed. The utility model sets up dilution mechanism. When the internal equipment of the dilution tank is damaged, the fixing assembly can quickly release the fixing of the cover, which greatly facilitates the maintenance of the equipment.
[0004] In the above technology, although the spray assembly can be used to spray mud, in actual use, the impact force of the spray flow mainly acts on the upper layer of the raw materials, and cannot effectively disturb the mud sediment at the bottom. As the production continues, the mud sediment will gradually form a compact accumulation layer at the bottom of the equipment. Especially for heavy mineral mud or fine mud particles with small particle size, gravity makes them more likely to settle at the bottom. Simply relying on spraying cannot suspend and remove them, so there is a certain limitation. Therefore, innovation is needed in this technology. UTILITY MODEL CONTENTS
