Embodiment Construction

[0021] The present invention will be specifically described below in conjunction with the accompanying drawings.

[0022] During the use of small-scale reaction devices (such as animal cell reactors, etc.), when the reaction process is carried out by placing the reaction device in a constant temperature environment (such as in an incubator), the temperature of the reaction process is controlled by the ambient temperature , while the ambient temperature is controlled by, for example, an incubator. The industry standard for animal cell culture devices "JB / T 20137-2011 Mechanically Stirred Animal Cell Culture Tank" has the following performance requirements for animal cell reactors:

[0023] 5.4.5 The temperature of the culture medium should be able to be set at room temperature below 37°C, and the allowable error range is ±0.2°C.

[0024] 5.4.6 The pH value of the culture solution should be able to be set within the range of 6 to 9, and the allowable error range is ±0.02.

Abstract

The invention discloses a high-precision and low-speed stirring system with low heat quantity, comprising a stirring device that comprises an upper cover, a lower cover, an electric motor and a stirring linkage device. The upper cover and the lower cover of the stirring device are connected mutually to form a housing of the stirring device; and a stirring bar is connected with the electric motor through the stirring linkage device. The stirring system further comprises a flow guide fan and a partition plate arranged between the upper cover and the lower cover of the stirring device; the stirring linkage device is arranged between the partition plate and the upper cover of the stirring device; the partition plate and the upper cover of the stirring device form an airflow layer; the wind power of the flow guide fan forms an airflow layer which forms convection with environmental air outside the device. By adopting the structure combining double boards with air guidance, heat generated by the electric motor is taken away through the forced convection exchange way of the flow guide fan and the environmental air, so that the temperature of the upper cover of the stirring device is substantially as same as the temperature of the environment, the bottom of a reaction device is heated substantially as same as other parts, and the reaction process is guaranteed to be performed in a controllable temperature state.

Description

technical field [0001] The invention relates to an electromechanical integrated experimental apparatus, in particular to a low-calorie, high-precision and low-speed stirring system. Background technique [0002] In the process of chemical and biological experiments, stirrers are often used. The stirrer includes a stirring container, a stirring bar in the stirring container, and a motor. The motor provides kinetic energy to the stirring bar to stir the liquid in the stirring container. . What is often used at present is a magnetic stirring device. The magnetic stirring device is driven by a micro-motor to generate a rotating magnetic field to drive the stirring bar in the container to stir the solution, so that the solution can obtain good heat and mass transfer conditions, and obtain uniform and sufficient temperature at the set temperature. Mixed reaction, so it can be widely used in biology, medicine, chemistry, chemical industry and other fields. [0003] During the us...
