Problems solved by technology

[0002] In the field of control, the control of liquid level and temperature has been widely used, and its advantages are well known in the industry. However, under small-scale conditions, such as small-scale microbial cultivation and comparative experiments on plant seed germination rates, it needs to be carried out and optimized under multiple temperature conditions. Option, systems that require multiple temperature comparison tests set in the same device

Embodiment Construction

[0022] Such as figure 1 The shown multi-connected temperature and liquid level control system includes a multi-connected tank 1 and a temperature and liquid level control system. The outer peripheral wall of the multi-connected tank 1 is made of thermal insulation material, with a base 23 at the bottom and a base 23 at the top. There are insulation cover 4. The outside of the multi-unit box 1 is also provided with a leveling instrument 2, and the upper part of the multi-unit box body 1 is also provided with a handle 3. in the slot. Such as figure 2 , image 3 As shown, the inside of the multi-unit box body 1 is composed of a plurality of heat preservation chambers 7, 8, and 9 arranged according to temperature increasing control, and a heat preservation and heat insulation partition plate 10 is arranged between the plurality of heat preservation chambers 7, 8, and 9 to separate, Prevent heat exchange between the various boxes inside the device and lose the function of main...

Abstract

The invention relates to the field of bioreactor liquid level heat preservation control, in particular to control of multilevel-linkage liquid level and multilevel temperature. An integral multilevel-linkage temperature and liquid level control device system capable of achieving temperature and liquid level linkage control is divided into two control subsystems: a heat preservation liquid liquid-level control subsystem and an intelligent heat preservation liquid temperature control subsystem, wherein multilevel temperature control is adopted for temperature control and divided into temperature independent control of a plurality of box bodies. The multilevel-linkage temperature and liquid level control device system can achieve influence on biochemical reactions and microbial cultivation aiming at temperature changes of different temperature segments, simultaneously temperatures of all heat preservation boxes can be adjusted, and multilevel temperature control is achieved.

Description

technical field [0001] The invention relates to the field of bioreactor liquid level heat preservation control, more specifically, it relates to the control of multi-stage linkage liquid level and multi-stage temperature, and the linkage control of temperature and liquid level can be realized in the designed device. Background technique [0002] In the field of control, the control of liquid level and temperature has been widely used, and its advantages are well known in the industry. However, under small-scale conditions, such as small-scale microbial cultivation and comparison experiments on plant seed germination rates, it needs to be carried out and optimized under multiple temperature conditions. Select a system that requires multiple temperature contrast tests to be assembled in the same device. Based on these specific requirements, it is necessary to design a multi-connected temperature and liquid level control system to achieve multi-temperature control and conduct c...
