Row type aquatic organism suspended sediment experimental device

Abstract

The invention relates to a row type aquatic organism suspended sediment experimental device which comprises an experimental container which is installed on a magnetic stirring apparatus base seat. A support used for placing a heating bar and an air inflation bar is arranged on one side of the magnetic stirring apparatus base seat. The heating bar and the air inflation bar are used for heating and inflating air to water inside the experimental container. A magnetic rotor is arranged on the bottom of the experimental container. The magnetic rotor moves in a circular mode under the effect of the magnetic stirring apparatus base seat. The experimental device enables aquatic organisms to carry out normal physiological activities under a suspended sediment state.

Description

technical field [0001] The invention relates to the technical field of aquatic organism toxicology, in particular to a row-type aquatic organism suspended sediment experimental device. Background technique [0002] At present, in the field of aquatic organisms (fish, shrimp and crab) toxicology research in China, self-made devices without uniform specifications and structures are used for experiments in the suspended state of sediment to meet the needs of their own experiments, and the generalization is low. Due to the limitations of conditions and design, many self-made devices have to meet the suspension state conditions, the structure of the device is relatively complicated, and the operation steps are cumbersome. All kinds of water pumps or inflatable water valves are generally used, resulting in higher production material costs. Moreover, due to the mechanical vibration of these water pumps and inflation valves, it will interfere with the normal physiological activitie...

AI Technical Summary

Problems solved by technology

Due to the limitation of conditions and design, many self-made devices have to meet the suspension state conditions, the structure of the device is relatively complicated, and the operation steps are relatively cumbersome.

Generally, all kinds of water pumps or inflatable water valves are used, resulting in higher production material costs

Moreover, due to the mechanical vibration of these water pumps and inflation valves, it will interfere with the normal physiological activities of aquatic organisms and have a certain impact on the reliability of toxicological test results.

At the same time, due to the inability to control the sufficient agitation of the sediment and the water body, the stability of the suspended state of the sediment is poor
