Description

Technical Field

[0001] The utility model relates to a water sample water quality detection bottle, in particular to a water sample centrifugal bottle. Background Art

[0002] In the process of surface water monitoring, after collecting water samples, in addition to the monitoring items with special requirements for standard analysis methods, the collected water samples need to be poured into a standing container to ensure that there is enough water sample to stand naturally for 30 minutes. For example, when collecting total phosphorus water samples, if there are still a lot of settleable solids in the water sample after standing naturally for 30 minutes, the water sample should be treated by extending the standing time or centrifugation according to the raw water turbidity measurement results. Therefore, the standing time of water samples with 200<NTU≤500 should be extended, and the upper water sample should be taken after standing naturally for 60 minutes. Water samples with NTU>500 should be settled by centrifuge. After centrifugation at 2000r / min for 2 minutes, the upper water sample should be taken. Although the conventional static method can stabilize the sedimentation, it takes a lot of time. When the centrifugal sedimentation method is used, the centrifugal bottle placed in the centrifuge generally adopts the same structure of the bottle body and the bottom of the bottle, which makes the centrifugal sedimentation method also need to run for a long time. Moreover, when taking out from the centrifuge, the consistent structure of the bottle body and the bottle body makes it easy to cause secondary turbidity due to shaking, which greatly reduces the centrifugal effect, affects the sedimentation effect of the water sample, and further affects the accuracy of water quality detection.

The outer surface of the bottle body 1 is wrapped with an anti-slip sleeve 15. The inner surfaces of the bottle body 1 and the cone 11 are evenly distributed with more than two baffles 14. The cone 11 with a conical structure below the bottle body 1 is embedded into the centrifuge, which makes it convenient for the bottle body 1 to be extracted from the centrifuge through the cone 11. At the same time, the structure of the cone 11 and the setting of the baffle 14 facilitate the sedimentation of the water sample inside the bottle body 1 by the centrifuge, and facilitate the sedimentation and fixation of the water sample into the bottom cylinder 12 below the cone 11.

Under the centrifugal action of the centrifuge, the sedimentation material passes through the baffle 14, the inner surface of the bottle body 1 and the inner surface of the cone 11 and settles and accumulates in the bottom cylinder 12. At the same time, the conical structure of the cone 11 makes it convenient for the user to easily put in or take out the bottle body 1 from the centrifuge, thereby reducing the problem of solid matter in the bottle body 1 floating up again after centrifugal sedimentation.
