Description

Technical Field

[0001] The utility model relates to the technical field of water quality resource monitoring, in particular to a portable suction filtration device. Background Art

[0002] Water sample monitoring refers to the monitoring of physical properties of environmental water bodies (rivers, lakes, seas, reservoirs and groundwater, etc.) and water pollution sources (domestic sewage and hospital sewage, etc.), monitoring of metal compounds, monitoring of non-metallic inorganic substances, monitoring of organic compounds, biological monitoring, determination of hydrological and meteorological parameters, and bottom sediment monitoring.

[0003] In actual operation, the existing portable filtration device pre-filters the impurities in the water sample through the filter on the extraction end. Therefore, the filter at the extraction end is easily clogged by impurities, resulting in a low filtration efficiency of the portable filtration device. For this reason, the prior art usually provides a cleaning device at the filter to clean the impurities accumulated on the filter. For example, Chinese patent application number CN202321080682.2 discloses a portable surface water filtration device, which has a toggle cleaning mechanism at the bottom of the filter, and the toggle cleaning mechanism is used to clean the impurities accumulated at the bottom of the filter. Under the action of the driving motor, the impurities accumulated at the bottom of the filter can be automatically toggled and cleaned during the extraction process, which can effectively reduce the risk of filter blockage during the extraction process and improve the filtration stability.

[0004] However, the portable filtration device disclosed above has some shortcomings. For example, the filter screen for primary filtration and the filter membrane for secondary filtration are both arranged inside the filtration device. After long-term use, the filter membrane is at risk of being blocked by impurities. It is not convenient to disassemble and replace the filter screen and filter membrane, and its practicality is poor.

[0005] To this end, the utility model provides a portable suction filtration device. Utility Model Content
