Description

Technical Field

[0001] This utility model relates to the field of polyaluminum chloride storage technology, specifically to a polyaluminum chloride storage tank. Background Technology

[0002] Polyaluminum chloride (PAC) is an inorganic substance, a new type of water purification material, and an inorganic polymer coagulant, often abbreviated as polyaluminum. PAC possesses adsorption, coagulation, and precipitation properties, but it has poor stability and is corrosive. If accidentally splashed onto the skin, it should be immediately rinsed with water. Production personnel should wear work clothes, masks, gloves, and rubber boots. PAC has advantages such as good stability after spray drying, wide applicability to various water areas, rapid hydrolysis, strong adsorption capacity, large and dense flocs, rapid sedimentation, low effluent turbidity, and good dewatering performance. Using spray-dried products ensures safety, reduces water accidents, and is very safe and reliable for residential drinking water. Therefore, PAC is also commonly referred to as high-efficiency polyaluminum chloride.

[0003] The authorized publication number "CN213922436U" describes "a polyaluminum chloride storage tank, comprising: anti-collision clamps, a heating circulating water pipe, a tank body, and a stirring shaft. The lower half of the outer wall of the tank body is fixedly connected to the anti-collision clamps by snap-fit, and the heating circulating water pipe is fixedly connected to the outer wall of the tank body by snap-fit. This utility model uses mixing protrusions to create turbulence during stirring, breaking the adsorption force between ions, so that the liquid aluminum chloride solution is mixed evenly and prevents precipitation and flocculation. When storing in cold weather such as winter, hot water is circulated into the heating circulating water pipe through a hot water pump and a hot water tank to heat the tank body, prevent the internal aluminum chloride solution from freezing, and ensure the normal use of the liquid aluminum chloride solution. The anti-collision clamps protect the tank body and the level gauge, ensuring the safety of the storage tank during transportation."

[0004] The aforementioned patent creates turbulence during stirring by using mixing protrusions, which breaks the adsorption force between ions and makes the liquid aluminum chloride solution mix evenly to prevent precipitation and flocculation. However, the aforementioned patent can only stir polyaluminum chloride, and the stirring effect is poor. When the concentration of aluminum chloride solution is high or the standing time is long, hard lumps that are not easy to dissolve will form. Stirring alone cannot prevent the precipitation of aluminum chloride particles, which will affect the subsequent use effect of polyaluminum chloride. Utility Model Content

[0025] In this implementation scheme: the stirring mechanism 3 inside the tank 2 increases the uniformity and fluidity of polyaluminum chloride, effectively preventing polyaluminum chloride from clumping, solidifying, and settling, and avoiding insufficient stirring that would affect the subsequent use of polyaluminum chloride. The mounting bracket 301 is used for the installation and placement of the conveying pipe 302. Each set of circulation components, in conjunction with the conveying pipe 302, can convey liquid polyaluminum chloride and transport the sediment at the bottom of the tank 2 to the upper part of the tank 2, ensuring the uniformity and fluidity of polyaluminum chloride. The conveying components, in conjunction with the conveying pipe 302, are used to convey solid polyaluminum chloride, facilitating uniform mixing of polyaluminum chloride.

[0026] Specifically, each set of circulation components includes a circulation pipe 303, a delivery pump 304, and a connecting pipe 305. The circulation pipe 303 is fixedly installed on one side of the outer wall of the delivery pipe 302 near the top edge. The delivery pump 304 is installed at one end of the circulation pipe 303. The connecting pipe 305 is fixedly installed at the output end of the delivery pump 304 and is embedded in the top of the outer wall of the tank 2.

[0027] In this embodiment: the polyaluminum chloride at the bottom of the tank 2 is extracted by the delivery pump 304, and the polyaluminum chloride at the bottom is transported to the upper part of the tank 2 through the delivery pipe 302, circulation pipe 303 and connecting pipe 305. The polyaluminum chloride is guided by the delivery pipe 302, circulation pipe 303 and connecting pipe 305 to form a uniform circulation flow, ensuring the uniformity and fluidity of the polyaluminum chloride in the tank 2 and avoiding the occurrence of sedimentation.

[0028] Specifically, the conveying components include a conveying motor 306, a rotating shaft 307, and a spiral blade 308. The conveying motor 306 is bolted to the top of the outer wall of the conveying pipe 302. The rotating shaft 307 is fixedly installed at the output end of the conveying motor 306 and is rotatably embedded in the top of the outer wall of the conveying pipe 302. The spiral blade 308 is fixedly sleeved on the outer wall of the rotating shaft 307.

[0029] In this embodiment: when the conveying motor 306 is powered on, it drives the rotating shaft 307 to rotate, and the rotating shaft 307 drives the spiral blades 308 to rotate, which can transport the polyaluminum chloride at the bottom to the upper part of the tank 2.

[0030] Specifically, the stirring component includes a stirring motor 309, a first gear 310, a second gear 311, and a stirring assembly.
