Description

Technical Field

[0001] The utility model relates to the technical field of liquid level measurement, in particular to a liquid level measurement device for a hydrated catalyst storage tank. Background Art

[0002] Hydration catalyst is an indispensable part of the cyclohexanol synthesis process. It is used in large quantities and needs to be stored in large tanks during daily production addition, start-up, shutdown and replacement. Since the hydrated catalyst has the characteristics of slurry, it is easy to be compacted during daily storage and use. As time goes by, the density of the lower catalyst shows an increasing trend, and even compacted nodules appear at the bottom, causing the measurement signal of the conventional liquid level gauge to be distorted. At the same time, during the operation of stopping and emptying the tank, the catalyst will inevitably entrain some oil-containing materials, corroding the measuring elements inside the liquid level gauge and causing damage to the measuring instrument. In existing production practices, the measurement of the liquid level of large storage tanks for hydrated catalysts requires the use of a liquid level metering device.

[0003] Most of the existing liquid level measuring devices are installed by knob type, which is troublesome to disassemble and fix. Moreover, most of the existing liquid level measuring devices need to drain the liquid inside the storage tank when fixing or disassembling, which is troublesome. At the same time, the existing liquid level measuring devices are not easy to clean. Utility Model Content
