Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an automatic solution preparation device and a powder dissolving method. Background technique [0002] A solution is a uniform and stable mixture composed of at least two substances, and the dispersed substance (solute) is dispersed in another substance (solvent) with molecules or smaller particles. Matter has three states of solid, liquid and gas at room temperature. Therefore, the solution also has three states, the atmosphere itself is a gas solution, and the solid solution mixture is often called a solid solution, such as an alloy. A general solution simply refers specifically to a liquid solution. [0003] Generally, the reaction rate of chemical reactions carried out in solution is relatively fast. Therefore, in the laboratory or in chemical production, in order to improve the reaction efficiency of two substances, they are often dissolved first, and then the two solutio...

Problems solved by technology

Therefore, in the laboratory or in chemical production, in order to improve the reaction efficiency of two substances, they are often dissolved first, and then the two solutions are mixed and shaken or stirred to speed up the reaction; in the field of environmental protection, often Prepare PAC and PAM powder into aqueous solution for coagulation sedimentation or sludge dehydration, etc. For this reason, how to improve the preparation efficiency of the solution is a problem that has been paid more attention to in the prior art. The solution preparation provided in the prior art is by using The solute and the solvent are mixed in the dissolving tank and then stirred to achieve the preparation of the solution. However, when the solution is rapidly prepared in large quantities, the solute is often dissolved in the solvent insufficiently and uniformly due to the excessive solvent content, resulting in low or low preparation efficiency of the solution. The concentration of the solution is uneven, which is not convenient for large-scale automated production; further, in winter, due to the low temperature of the solvent, the prior art will cause difficulty in solute dissolution, especially the PAM powder will form a linear solution in water, and the prepared solution Extremely inhomogeneous, high solid content
