Description

Technical Field

[0001] The utility model relates to the technical field of water detection, in particular to a water sample filtering device for occupational health environment detection. Background Art

[0002] Occupational environment monitoring is to detect the operator's working environment in a planned and systematic manner and analyze the nature of toxic and harmful factors in the working environment. Environmental monitoring is the basis for scientific environmental management and environmental law enforcement supervision, and is an essential basic work for environmental protection. The core goal of environmental monitoring is to provide data on the current status and change trend of environmental quality, judge environmental quality, evaluate the current main environmental problems, and serve environmental management. When detecting water bodies, a filtering device is needed to filter them to ensure that the water samples do not contain impurities such as silt.

[0003] Common filtering devices generally consist of a housing and a filter screen. When in use, water is introduced into the box body through a pipeline, so that it flows into the filter screen, thereby removing impurities in the water. However, due to the fixed position of the pipeline, when the water is introduced, only a certain area of the filter screen can be filtered, resulting in a constant filtering area. Over time, the filter screen will be blocked, affecting its filtering speed and reducing the service life of the filter screen, which cannot meet the working requirements of water sample filtering. Therefore, a water sample filtering device for occupational health environment detection is proposed. Summary of the Utility Model
