Description

Technical Field

[0001] The utility model relates to the technical field of mine equipment, in particular to a mine drainage detection device. Background Art

[0002] A mine is a general term for the shafts, chambers, equipment, ground buildings and structures that form an underground coal mine production system. Water often gathers in low-lying areas underground in coal mines, so it is necessary to discharge the mine water. Since mine water contains heavy metal elements, direct discharge to the ground will cause soil erosion, salinization, and vegetation damage. The mine water needs to be tested and treated before it is discharged, so a mine drainage detection device is needed.

[0003] At present, there are still some shortcomings in the traditional mine drainage detection device. The mine drainage detection device usually installs a filter to filter impurities in the mine water before detecting and processing the mine water. A large amount of impurities will be attached to the filter over a long period of time, and the filter is installed inside the drainage detection device by bolts. The staff needs to use tools every time to disassemble it, which makes it inconvenient for the staff to disassemble and install the filter, and the process is cumbersome. For this reason, we propose a mine drainage detection device. Utility Model Content
