Detection device for the dissolution time of solid powdery substances in solution

Abstract

The invention relates to a device for detecting the dissolution time of a solid powdery substance in a solution. The device comprises a dissolution pool, a circulating pump, an optical detection pool, an optical emitter and an optical receiver, wherein the dissolution pool, the circulating pump and the optical detection pool are sequentially communicated through a pipeline to form a loop; the optical emitter and the optical receiver are arranged on the two sides of the optical detection pool respectively; a light path emitted by the optical emitter passes through the optical detection pool and then is received by the optical receiver. According to the device, the dissolution time of the solid powdery substance in the solution can be accurately measured by reasonably arranging all the parts, and a test is accurate and reliable and cannot be influenced by the factors such as colors, absorbance, physical and chemical states or properties of the solution or solid state powder particles; actual industrial operation conditions are simulated by additionally arranging devices for stirring, heating, pressurizing and the like; an application space is wide; the physical and chemical properties of a sample cannot be changed; nondestructive online monitoring can be realized, and the device is particularly suitable for being applied to relevant processes in the fields of chemical industry and material manufacturing where the automation degree is higher or precise control is needed.

Description

technical field [0001] The invention relates to analysis and detection equipment, in particular to a detection device for the dissolution time of a solid powder substance in a solution. Background technique [0002] In chemical industry production, solid reactants are generally dissolved before reacting. The dissolution process of a solid in a solution can be a chemical process or a physical process. For the dissolution mentioned in this case, the ratio of solid to solution must be less than the solubility of the solid in the solution under this condition, so no solid residue can be used as the criterion for judging the end of dissolution. The complete dissolution mentioned in this case refers to the state in which the solid powder is added into the liquid and after a certain change, the only uniform liquid phase solution is formed. [0003] The time required for a certain amount of solid substance to completely dissolve in a given solution under given conditions is referr...

But currently, there is no reliable and accurate device for measuring the dissolution time of substances

In addition, for substances with the same chemical composition, their physical states such as crystal structure or morphology are different, which will also have a great impact on the dissolution rate. When manufacturers choose raw materials, they urgently need a reliable device to measure different sources. material dissolution time
