Stirring paddle and automatic temperature control stirrer using same

Abstract

The invention discloses a stirring paddle and an automatic temperature control stirrer using same. The stirring paddle comprises a stirring shaft, a paddle group and a paddle group fixing frame, wherein the paddle group fixing frame is fixed together with the middle part of the paddle group; and the stirring shaft runs through the edge of the paddle group fixing frame to be connected with the paddle group through a gear transmission mode. The paddle group fixing frame comprises an upper hollow-out fixed plate and a lower hollow-out fixed plate, which are the same as each other; and the paddle group is fixed between the upper fixed plate and the lower fixed plate. Through the adoption of gear transmission connection, constant instantaneous transmission ratio can be guaranteed, high stability is achieved and accurate and reliable transmission is achieved. As the stirring shaft is biased from the center, the stirring paddle disclosed by the invention is beneficial for containers to accommodate heated materials and convenient for operators to do relevant operations so as to eliminate safety problems. The automatic temperature control stirrer using the stirring paddle has an automatic stirring function, so that the temperature of a heating medium is uniform and heat transfer speed is increased, so that uniformity of heat conducted to the heated materials is guaranteed.

Description

technical field [0001] The invention relates to a water bath or oil bath heating device, in particular to a stirring paddle and an automatic temperature control stirrer using the paddle. Background technique [0002] In the production process of medical and health, light industry food, petrochemical, bioengineering, life science, physical and chemical testing, analysis, synthesis and other production enterprises, as well as in the laboratories of universities and colleges, scientific research units for material temperature control heating experiments or During research, it is often necessary to use a water bath or oil bath heating device to heat the substance. [0003] Traditional water bath or oil bath heating devices mostly use electric heating tubes as heat sources and use thermometers to measure temperature. Electric heating tubes mostly use immersion heating, which not only consumes a lot of power, but also has low utilization rate of electric energy. Waste heat will ...

AI Technical Summary

Problems solved by technology

Electric heating tubes mostly use immersion heating, which not only consumes a lot of power, but also has low utilization rate of electric energy. It will also generate waste heat to increase the temperature of the heating medium, making it difficult to accurately control the temperature

[0004] In addition, the above-mentioned water bath or oil bath heating device only has a heating function and does not have an automatic stirring function. During the heating process, it often only relies on the natural diffusion of the temperature of the heating medium, which may easily cause uneven temperature conduction.

Some operators set up stirring paddles during use, and some add a small stirrer or a small paddle to stir or stir locally, so the temperature cannot be accurately controlled.

And the motor directly drives the stirring shaft of the stirring paddle to move. The stirring shaft is located in the center of the water bath or oil bath container.
