Energy-saving self-stirring bioreactor

Abstract

The invention discloses an energy-saving self-stirring bioreactor. The bioreactor comprises a reaction box, wherein an annular heating plate is embedded in the inner wall of the reaction box, a stirring rod is rotatably connected to the bottom in the reaction box through a rotating shaft seal. The lower end of the reaction box is provided with a circular groove, and the lower end of the rotating shaft penetrates through the lower end of the reaction box and is fixedly connected with a disc. A cavity is disposed in the disc, a thermoelectric power generation piece is rotatably connected into the cavity through a cross rod, the side wall of the heating plate is connected with the top in the cavity through a heat conduction strip, a plurality of cooling fins are fixedly connected to the bottom in the cavity, and an electromagnet is embedded into the disc. Current is generated on the thermoelectric power generation piece, so that the electromagnet is electrified to generate magnetism, thepermanent magnet and the electromagnet repel each other, so that the electromagnet rotates forwards under the action of magnetic repulsion of the permanent magnet to drive the rotating shaft to rotate, and making the stirring rod to stir microorganisms in the reaction box, so that the microorganisms are uniformly heated and the reaction efficiency is accelerated.

Description

technical field [0001] The invention relates to the technical field of biological engineering treatment, in particular to an energy-saving self-stirring bioreactor. Background technique [0002] Bioreactors are equipment used for microbial cultivation. Small bioreactors are often used in laboratories for microbial cultivation. In the process of microbial cultivation, in order to ensure the normal reaction of microorganisms, the microorganisms need to be heated at a constant temperature and Add nutrient solution. [0003] In the actual operation of the laboratory, when the microorganisms need to be cultivated, the microorganisms are often stirred artificially from time to time, which makes the experimental operation of the microorganisms more cumbersome, and when adding the nutrient solution to the reactor, it is always It is necessary to open the lid on the reactor to add, so that the microorganisms in the reactor will be in direct contact with the air, making the microorga...
