Online detection device and method for viscosity of sodium alginate glue solution

Abstract

The invention discloses an online detection device and method for viscosity of a sodium alginate glue solution. The online detection device comprises a bottom plate, a homogenizing kettle is arranged at the top of the bottom plate, a supporting block and a control box body are fixedly connected to the top of the bottom plate, a stirring assembly is arranged in the homogenizing kettle, and a driving motor is fixedly connected to the axis of the top of the homogenizing kettle. Materials are homogenized through the stirring assembly, so that the viscosity of the materials is balanced. After the materials are conveyed to a detection assembly through a material pumping assembly, the materials are extracted from the top, the middle and the bottom of the materials to be detected. Through a linkage structure of an adjustment assembly and the detection assembly, a first viscosity sensor, a second viscosity sensor and a third viscosity sensor can synchronously go deep into a detection cylinder for detection, the sensing ends of the sensors can be automatically cleaned when the sensors are pulled out. The real-time detection precision is improved. Data of three different positions is compared, and an accurate data value is obtained as the measured viscosity when unified data are obtained through comparison. The production quality of the sodium alginate glue solution can be ensured.

Description

technical field [0001] The invention relates to the technical field of on-line detection of viscosity, in particular to an on-line detection device and method for the viscosity of sodium alginate glue. Background technique [0002] As we all know, sodium alginate, as a natural polymer substance, is widely used in chemical, Biology, medicine, food and other fields. With the development of the application of sodium alginate, the market has higher and higher requirements for the quality and stability of sodium alginate. And the viscosity control of the sodium alginate glue solution in the production process is particularly important. [0003] The automatic real-time measurement of the viscosity value of the material can be realized through the viscosity online measurement system, but the adhesion of the material on the viscosity sensor will affect the accuracy of the continuous measurement, and the texture of the material is not uniform during the measurement, such as the dif...
