[0002] During the preparation of acid solution, generally, a high-concentration solute is directly mixed with a solvent and circulated repeatedly for many times to finally achieve uniform mixing. When preparing dilute hydrochloric acid, it is necessary to control the mixing ratio of materials and pay attention to stirring to make the materials distributed and fully fused to prevent the materials from quickly sinking and accumulating, which affects the quality of the prepared dilute hydrochloric acid. A dilute hydrochloric acid preparation device disclosed in the prior art with publication number CN214915019U includes a concentrated hydrochloric acid bottle, a pure water bottle, a dilute hydrochloric acid preparation bottle, a hose, valves and a stirrer. The concentrated hydrochloric acid bottle and the pure water bottle are higher than the top of the dilute hydrochloric acid preparation bottle. The concentrated hydrochloric acid bottle and the pure water bottle are connected by a hose. The hose is successively provided with a first valve and a second valve. A hose with a third valve is provided between the first valve and the second valve. The hose with the third valve communicates with the inside of the dilute hydrochloric acid preparation bottle. The concentrated hydrochloric acid bottle is placed on an electronic scale. The dilute hydrochloric acid preparation bottle is equipped with a stirrer, a circulation jacket and a fourth valve at the bottom.
