TECHNICAL FIELD

[0001] The present application relates to the field of chemical processing technology, in particular to a reaction kettle internal viscosity real-time measuring device. BACKGROUND

[0002] The reaction kettle is widely used in petroleum, chemical, rubber, pesticide, fuel, pharmaceutical, food and other industries. At present, the control system of the reaction kettle is used more and more widely, and the monitoring of the reaction parameter condition is also more and more important. At present, the conventional temperature and pressure measurement has become the basic parameter of the reaction kettle measurement, and the viscosity parameter is a factor affecting the stirring effect in the kettle body for the reaction kettle. At the same time, monitoring the viscosity range of the material in the kettle body has a great effect on checking the quality of raw materials, improving the product pass rate and ensuring product consistency, so the viscosity has become an important parameter of the reaction kettle measurement.

[0003] In the prior art, during the processing of the material in the reaction kettle, the operator needs to sample the material in the kettle body at a set time interval and transfer the material to the viscosity tester for detecting the viscosity of the material. Among them, the common viscosity tester mainly includes a viscosity tester body, and a detection head is detachably installed on the viscosity tester body through threads. When detecting the sample material, the operator needs to place the container containing the sample raw material under the detection head, and the viscosity tester detects the viscosity of the sample material.

[0004] However, the operation of sampling at a set time interval and using the viscosity tester to sample the sample material is cumbersome, and the viscosity change of the material in the kettle body cannot be grasped in real time, so there is room for improvement. Invention content
