Description

Technical Field

[0001] The utility model relates to a test device, in particular to an algae rapid sedimentation device. Background Art

[0002] Algae research plays an extremely important role in environmental science and biology, especially in water quality monitoring and ecosystem health assessment. The traditional method of algae sedimentation analysis uses the Lugol reagent sedimentation method. Although the sedimentation method has been widely used, it is time-consuming and greatly reduces the efficiency and response speed of the research. Lugol's reagent is an iodine-containing stain that reacts with polysaccharides in algae cells to stain the algae, so that they can be observed and counted under a microscope. This is a key step in tracking and understanding the life cycle and dynamics of algae.

[0003] However, existing technologies require that samples be allowed to settle naturally for up to 48 hours after adding Lugol's reagent. This disadvantage is quite significant for environmental and biological research, as well as industrial applications, which require rapid results. In addition to being inefficient, this long sedimentation process may also cause biodegradation of the sample during the waiting period, thus affecting the accuracy of the sedimentation results.

[0004] Therefore, how to shorten the sedimentation time of Lugol's reagent is a technical problem to be solved urgently by those skilled in the art. Summary of the invention

[0005] In order to solve the problems in the prior art, the utility model provides an algae rapid sedimentation device.

[0006] The invention object of the utility model is to provide an algae rapid sedimentation device, which accelerates the mixing process of Lugol reagent by mechanical stirring, effectively shortens the overall sedimentation time (approximately from the traditional 48 hours to 24 hours), while maintaining the integrity of the sample and the accuracy of the experiment.

[0007] The utility model provides an algae rapid sedimentation device, comprising an algae sedimentation column, a magnetic rotating motor, a magnetic stirring rotor and a rotating blade, wherein the magnetic rotating motor is installed on the algae sedimentation column, the magnetic stirring rotor is adsorbed on the magnetic rotating motor, the magnetic stirring rotor is connected to the rotating blade through a rotating shaft, and the rotating blade is arranged in the algae sedimentation column.

[0008] As a further improvement of the utility model, the upper part of the algae sedimentation column is a cylindrical bottle body, and the lower part is a cone body. The upper end of the cone body is connected to a waste pipe, and a first knob switch is installed on the waste pipe.

[0009] As a further improvement of the utility model, the conical body is communicated with the cylindrical bottle body, the lower part of the conical body is connected with a sediment collection tube, and a second knob switch is installed on the sediment collection tube.

[0010] As a further improvement of the utility model, an algae collection bottle is placed below the outlet of the sedimentation collection tube.

[0011] As a further improvement of the present invention, the rotating blades are arranged inside the cylindrical bottle body.

[0012] As a further improvement of the utility model, there are at least two rotating blades which are arranged vertically and spaced apart along the axis of the cylindrical bottle body.

[0013] As a further improvement of the utility model, the cylindrical bottle body is connected to a sedimentation column upper cover, the magnetic rotating motor is installed above the sedimentation column upper cover by a snap, and the magnetic stirring rotor is installed below the sedimentation column upper cover.

[0014] As a further improvement of the utility model, the rotating shaft is a flexible rotating blade connecting line.

[0015] The beneficial effect of the utility model is that through the above scheme, the magnetic rotating motor drives the rotating blades to rotate by driving the magnetic stirring rotor to rotate through the magnetic attraction force, thereby realizing mechanical stirring of the Lugo reagent, accelerating the mixing process of the Lugo reagent through mechanical stirring, and effectively shortening the overall sedimentation time (approximately from the traditional 48 hours to 24 hours), while maintaining the integrity of the sample and the accuracy of the experiment.

[0026] The upper part of the algae sedimentation column 5 is a cylindrical bottle body 13, and the lower part is a conical body 14. The upper end of the conical body 14 is connected to a waste discharge pipe 8, and a first knob switch 9 is installed on the waste discharge pipe 8. The first knob switch 9 is used to control the waste discharge of the waste discharge pipe 8.

Alternatively, the sedimentation column cover may not be provided, and the magnetic rotary motor 2 may be directly mounted on the algae sedimentation column 5.

[0033] The magnetic rotating motor 2 is detachably connected to the algae sedimentation column 5, so the magnetic rotating motor 2 can be removed for filling operations. If a sedimentation column cover is used, the sedimentation column cover and the cylindrical bottle body 13 are detachably connected. If the sedimentation column cover is not used, the magnetic rotating motor 2 and the cylindrical bottle body 13 are detachably connected.
