Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mineral processing, in particular to a sampling device for tailings analysis. Background Art
[0002] The flocculation mechanism involves two processes: coagulation and flocculation. Coagulation is the process by which colloidal particles destabilize and form fine aggregates, while flocculation is the process by which these fine aggregates, bridged by a flocculant, form larger flocs. During the tailings slurry thickening process, the overflow water can become turbid. To improve the efficiency of the tailings thickener and the quality of the overflow water, laboratory testing is required to determine the appropriate flocculant.
[0003] Currently, when studying the properties of different reagents, it is necessary to develop a method to allow the slurry to freely settle after adding different reagents under the same experimental conditions, and then extract an equal amount of the upper suspension liquid after the same settling time to determine the suspended matter content during the period. However, due to limited laboratory operating personnel, sampling is usually performed on multiple samples in sequence. This results in different free settling times for the slurry in each test tube (when the slurry in one test tube is sampled, the slurry in the remaining test tubes continues to freely settle), which violates the experimental condition of "same settling time". It also cannot ensure that the depth of insertion into the slurry is consistent during each sampling, which increases sampling errors, reduces measurement accuracy, and is inconvenient. Utility Model Content

It is simple to use and easy to operate, and can effectively solve the problems in the background technology.

[0006] As an optimal technical solution of the present invention, the circular test tube rack includes a bottom plate, a chassis and a limit plate. The chassis is rotatably set on the bottom plate. The upper surface edge of the chassis is provided with evenly distributed placement grooves. The limit plate is installed on the chassis through a vertical rod, and the limit plate is provided with a limit groove corresponding to the placement groove.
