Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, specifically to a stirring device for water quality testing. Background Technology

[0002] Water quality testing involves collecting water samples and using techniques such as chemical analysis and instrumental testing to determine their physical, chemical, and biological indicators. This assessment evaluates whether the water quality meets drinking water, industrial water, or environmental standards, providing a scientific basis for pollution control and resource protection.

[0003] Water quality testing often requires the addition of reagents. Stirring can eliminate the stratification of water samples and reagents, allowing for more thorough molecular-level contact and avoiding errors caused by incomplete local reactions. Therefore, a stirring device is required. Stirring in a fixed position can easily create "mixing dead zones" near the edge, bottom, or liquid surface of the container, resulting in insufficient contact between the reagents and the water sample. At the same time, it is not convenient to raise or lower the stirrer. Stirrers at a fixed height are usually located in the middle of the container. If the water sample volume is small, the stirring paddle may not be able to reach the vicinity of the liquid surface or the bottom of the container, resulting in slow diffusion of the upper reagent and sedimentation of the bottom particles.

When it is necessary to adjust the height of the stirrer 92, start the first motor 61. The first motor 61 drives the threaded rod 62 to rotate, thereby driving the lifting plate 71 to move up and down along the threaded rod 62, which in turn causes the mounting plate 72 and the stirring assembly 9 mounted on the rotating component 8 to move up and down until the stirring assembly 9 is adjusted to the appropriate depth and the drive of the first motor 61 stops. Then start... The second motor 111 drives the rotating rod 112 to rotate, which in turn drives the connecting rod 83 to rotate. When the connecting rod 83 rotates, it drives the gear 113 to rotate on the outside of the gear plate 12. Under the action of the rotating track of the gear plate 12, the stirring assembly 9 achieves a combined revolution and rotation motion. At this time, the stirrer 92 rotates under the rotation of the connecting rod 82 to fully stir the water sample in the stirring tank 4. After the preset stirring time is reached, the second motor 111 is turned off, and the stirrer 92 stops stirring. Then, the first motor 61 reverses to reset the stirring assembly 9, and the stirring tank 4 can be taken out for subsequent water quality testing.
