AI Technical Summary

Problems solved by technology

However, this method has the following disadvantages: (1) when the liquid level of the reaction system is low, the temperature measurement will encounter difficulties due to the limitation of the length of the temperature conduit, and non-standard equipment is often used, such as the way of side openings to the reaction kettle to be resolved
(2) When the viscosity of the reaction system is large and the stirring speed is fast, the temperature pipe will bend due to the large torque and even crack at the welding point with the kettle mouth
However, the temperature measurement device involved in the above patents is powered by batteries, which has the following two defects: one is that the working environment of general batteries should not be too high, and for high temperature reactions, the temperature of the stirring shaft is higher, and there is a danger of explosion when using common batteries; Batteries have a short service life, limiting their use in situations that require long periods of continuous stirring

Abstract

The invention aims to overcome the disadvantages in the prior art and provides a novel mixing device that is easy to operate and good in universality and has temperature display function by integrating a stirrer and a temperature meter. The novel mixing device avoids the problems that the prior art has strict requirement for volume and viscocity of a material system to be mixed, the temperature meter can not be contact directly with the system to be measured to protect the temperature meter from corrosion and mechanical wear by the material system. The stirrer rotates mechanically and converts the mechanical energy partially into the electric energy, to supply power to the temperature meter under stirring conditions. The temperature meter is powered by an external power supply under static conditions. The device smartly solves the problem simply caused by power supply of battery.

Description

Technical field [0001] A new type of stirring device that can self-power during the stirring process and measure the temperature of the system through a thermal resistance or thermocouple, which is used in the fields of chemistry, physics, biomedicine, and food processing. Background technique [0002] Stirring operation and temperature control have a wide range of applications in the fields of chemistry, physics, biomedicine, and food processing. Both operations are completed by two independent devices. Taking the reactor used in the chemical industry as an example, the temperature measurement is usually by installing a temperature measuring tube on the reactor, adding heat transfer oil to the tube, and then measuring the temperature of the reaction system with a mercury thermometer or an alcohol thermometer. Under normal circumstances, this method can meet the needs of production. However, this method has the following shortcomings: (1) When the liquid level of the reaction sys...
