Description

Stirring device for bacterial liquid culture Technical Field The utility model belongs to the technical field of stirring equipment, and particularly relates to a stirring device for bacterial liquid culture. Background The bacterial liquid is a suspension formed by mixing microorganisms with a liquid medium, and is mainly used in the fields of scientific research, industry, agriculture and medicine, and stirring is a key operation link in the preparation process of the bacterial liquid so as to promote the uniformity of mixing the microorganisms with the liquid medium, improve the oxygen transmission efficiency, prevent precipitation and caking, optimize the temperature and the metabolic environment and the like. When the traditional laboratory is used, manual mixing is adopted, time and labor are wasted, the traditional laboratory is more troublesome, an automatic stirring device is adopted for carrying out the traditional laboratory, for example, chinese patent publication No. CN209010510U discloses a stirring medium for culturing bacterial liquid, the traditional laboratory comprises a culture medium and a stirring rod arranged in the culture medium, a motor arranged below the culture medium, the output end of the motor penetrates through the culture medium and is connected with the center of the stirring rod, the stirring rod is driven by the motor to rotate, so that the stirring is realized, the manual stirring is replaced, the stirring efficiency is improved, the stirring uniformity is improved through the height position of the stirring rod in the culture medium, but the size of the stirring rod in the vertical direction is not adjustable, if bacterial liquid in the culture medium is more, the stirring can only be carried out at the middle position of the height direction of the culture medium, so that the stirring of the bottom and the top of the culture medium is limited, the stirring is inconvenient to detach and the washing is difficult.
