Layered sampling device and analysis system

Abstract

The invention discloses a layered sampling device and an analysis system. The layered sampling device comprises a bracket part, a sampling part and a driving part for driving the sampling part to lift, wherein the driving part is fixed on the bracket part; the sampling part is wound on the driving part; the layered sampling device also comprises a measuring part and a turnover part, wherein the measuring part is arranged on the driving part and used for measuring the travel distance of the sampling part; and the turnover part comprises an assembly which is fixedly arranged on the support partand arranged along the advancing direction of the sampling part, and the assembly is detachably connected with the sampling part in a hanging manner. The multi-depth sampling device provided by the invention realizes sampling at different depth positions, can accurately obtain the descending height of the sampling part, and can obtain the height position and the boundary position of the clear liquid layer of a settling tank; and after the sample is used up, a sampling cup can be automatically turned over to empty the sample.

Description

technical field [0001] The present invention relates to the interdisciplinary fields of machinery, microelectronics, measurement, etc., and in particular, relates to a layered sampling device for different liquid layers in a liquid-solid separation settling tank, and also relates to an analysis system including the above-mentioned layered sampling device. Background technique [0002] In alumina production or other wet processes, the slurry should be separated from liquid to solid in the separation settling tank, and the bottom flow of the settling tank will go to the washing settling tank for washing and separation. Settling tank operation often becomes the bottleneck of production, and it is very important to control its normal operation. Therefore, it is necessary to measure the height of the clear liquid layer of the settling tank from time to time during production. When the height of the clear liquid layer is maintained at 5-8m or above, it indicates that the production...

Problems solved by technology

Since the probe with electronic components cannot withstand high temperature and high alkali environment for a long time, and the signal transmission wire is unstable in high temperature, the detection accuracy is reduced, and even the instrument is damaged. The optical fiber sensor using the mirror light source is more It is easily affected by the complex composition and high alkali alumina in the settling tank, resulting in the limitations of low detection accuracy and high cost in actual use

[0004] In summary, because the alumina dissolution process has the characteristics of high temperature, high alkali and easy scarring, no matter which method is used to measure the height of the alumina solution layer, the reliability of the measurement data is poor, the life of the equipment is short, and the detection parts need to be replaced frequently , the cost of industrial use is high, so that the detection of the composition of the alumina liquid layer to achieve online real-time monitoring technology is limited in industrial applications
