Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyaluminum chloride production and processing technology, and in particular to a raw material impurity removal device for the production of polyaluminum chloride. Background Technology
[0002] The core raw materials for producing polyaluminum chloride (PAC) are the aluminum source and the acid source. Some processes also require regulators to control product quality. The aluminum source is the main substance providing aluminum in PAC, determining the product's basic purity and cost. It is generally bauxite, aluminum slag, or aluminum hydroxide. The acid source reacts with the aluminum source to generate an aluminum-containing chloride solution, providing conditions for subsequent polymerization reactions. It is generally hydrochloric acid or sulfuric acid. Regulators are mainly used to adjust the pH value during the reaction process, control the degree of polymerization, and ultimately affect the product's performance indicators. They are generally sodium hydroxide, calcium carbonate, or calcium aluminate powder.
[0003] When using waste aluminum slag as the aluminum source to produce polyaluminum chloride, it is often necessary to remove impurities to ensure the purity of the product and avoid negative impacts on the production process and the final result. This is where impurity removal equipment comes in.
[0004] A raw material impurity removal device for polyaluminum chloride production disclosed in Chinese patent CN222931235U can realize continuous vibration of the filter plate, thereby achieving effective screening of raw materials. It also shares a drive source with the collection component, thus greatly improving the efficiency of screening and impurity removal. However, compared with existing technologies and comparative solutions, this impurity removal device still has the following problems in actual use:
[0005] Because waste aluminum slag contains lubricants and cutting fluids used in aluminum processing, and its main component is mineral oil, when it is screened, the viscosity of the lubricants and cutting fluids causes them to mix with the fine aluminum slag powder to form a mixed flocculent. This flocculent is much more viscous than aluminum slag and aluminum powder, and its particle size is close to or slightly larger than the sieve openings. During the screening process, it does not detach with vibration, but adheres to the surface of the sieve and even to the mesh openings. It cannot pass through the sieve openings and is difficult to shake off by vibration, causing the mesh openings to become clogged, affecting the screening effect, and requiring frequent shutdowns for cleaning, which reduces the screening efficiency.
