Description

Technical Field

[0001] The utility model relates to the field of mineral processing pulp sampling, in particular to a telescopic self-luminous pulp sampling spoon for sampling in a closed space. Background Art

[0002] During the mineral processing process, each process has strict requirements on the state of the slurry. In order to better ensure the state of the slurry, it is usually necessary to sample and analyze the slurry. Sampling spoons are widely used in mineral processing plants as slurry sampling tools.

[0003] When a slurry sampling spoon is used in an enclosed space, the lack of light and unclear vision can lead to operational risks. For example, when sampling at the discharge port of a grinding mill, the insufficient light in the enclosed space can easily cause the spoon to touch the rotating parts and cause mechanical damage. In addition, the lack of light also makes it difficult for the sampling spoon to observe the internal sampling conditions in real time, which can easily lead to sampling errors. Therefore, how to effectively reduce the operational risks of the sampling spoon head while avoiding sampling errors is a key issue that needs to be addressed in the design of a telescopic self-luminous slurry sampling spoon for sampling in enclosed spaces. Utility Model Content
