Description

Technical Field

[0001] This utility model belongs to the field of polyaluminum chloride treatment technology, and in particular relates to a device for preventing polyaluminum chloride particles from caking. Background Technology

[0002] If polyaluminum chloride granules are not sufficiently dried after production, they will absorb water and clump together. These clumps are difficult to break up, and during use, they can easily clog the feed inlet, dissolving tank inlet, or pipelines of the dosing equipment, leading to dosing interruptions. Large clumps of polyaluminum chloride granules require a longer time to dissolve completely, and encapsulation may occur during the dissolution process, resulting in uneven solution concentration and insufficient utilization of the active ingredients. Directly drying the produced polyaluminum chloride granules is inefficient because of their strong hygroscopicity, requiring additional humidity control in the drying environment. Drying cannot break down the clumps and takes a long time to completely dry, resulting in low efficiency.

[0003] To address this issue, we provide a device for preventing polyaluminum chloride particles from caking, thereby solving the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a device for preventing polyaluminum chloride (PAC) particles from caking. This device involves installing a turning component in a processing cylinder, with a shaft tube at the upper end of the turning component. The shaft tube passes through the cylinder cover at the upper end of the processing cylinder, connecting to an air inlet assembly. A set of vent pipes is connected to the lower side wall of the shaft tube, and a stirring pipe extends downwards from one end of the vent pipes. The PAC particles to be prevented from caking are poured into the processing cylinder. The air inlet assembly blows external air into the shaft tube, allowing the air to enter the PAC particle pile through the vent holes on the side wall of the stirring pipe. This allows the air to escape from the PAC particle pile, carrying away moisture and achieving a drying effect. The turning component also turns the PAC particles at the bottom of the processing cylinder to the top, decomposing any caking particles within it, thus achieving the anti-caking effect.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

The drying component 3 includes a shaft tube 301, a set of vent pipes 302, and an air inlet assembly 303. The turning component 2 is installed in the processing cylinder 1, and the shaft tube 301 is installed at the upper end of the turning component 2. The shaft tube 301 passes through the cylinder cover 101 at the upper end of the processing cylinder 1, connecting the shaft tube 301 to the air inlet assembly 303. A set of vent pipes 302 is connected to the lower side wall of the shaft tube 301, and one end of the vent pipes 302 extends downwards. The stirring tube 302a pours the polyaluminum chloride granules that need to be prevented from caking into the processing cylinder 1. The air inlet component 303 blows external air into the shaft tube 301, so that the external air enters the polyaluminum chloride pile from the air outlet on the side wall of the stirring tube 302a, and the air is discharged from the polyaluminum chloride granule pile, taking away the moisture in it, thereby achieving the technical effect of drying. The turning component 2 turns the polyaluminum chloride granules at the bottom of the processing cylinder 1 to the top, and the caking polyaluminum chloride granules are decomposed in the turning component 2, thereby achieving the technical effect of preventing caking.
