Full-automatic filtering device of water sample of in-situ environment water body monitor

Abstract

The invention provides a full-automatic filtering device of a water sample of an in-situ environment water body monitor. The full-automatic filtering device is characterized in that a winding-drum-shaped filtering membrane belt is placed in a filtering membrane conveying box at the outer side of a device shell; a belt head of the filtering membrane belt penetrates through the device to be fixed on a winding shaft which is located in a filtering membrane collecting box at the other side of the device shell and is connected with a membrane collecting stepping motor; the device is internally provided with a filtering membrane conveying mechanism; one part, in the device, of the filtering membrane belt is located between cone bodies corresponding to a pair of central holes and can be tightly jointed and can also be completely separated; and a water sample inlet and a water sample outlet are respectively connected with the central holes of the cone bodies. The membrane collecting stepping motor in the filtering membrane collecting box and a membrane conveying driving stepping motor of a filtering membrane conveying mechanism rotate synchronously; and the membrane collecting stepping motor pulls a filtering membrane to move towards the direction of the filtering membrane collecting box. Meanwhile, the membrane conveying driving stepping motor drives a conveying belt to move so that a membrane pressing groove and a membrane pressing roller on the conveying belt can move along with the conveying belt, and are overlapped to clamp the plane of the filtering membrane belt, and the filtering membrane collecting box can move along one direction. When the cone bodies are completely separated, the filtering membrane belt moves to be automatically replaced; and the cone bodies are tightly combined to have a filtering effect on the filtering membrane.

Description

technical field [0001] The invention relates to in-situ monitoring of environmental water bodies, in particular to water sample processing by an in-situ monitor of environmental water bodies, and more particularly to an automatic filtering device for water samples of an in-situ monitor of environmental water bodies. Background technique [0002] Inorganic salts that are easily absorbed by plants, such as nitrate-nitrogen, nitrite-nitrogen, ammonium nitrogen, and phosphate, in water are usually called nutrients. When the nutrient content in the water body is too high, it is called eutrophication of the water body. The enrichment of the water body will cause a certain dominant plankton in the water body, especially the algae, to multiply, consume a lot of dissolved oxygen, the water quality will deteriorate, the aquatic animals such as fish and shrimp cannot survive, and the ecological balance of the water body will be destroyed, resulting in blooms or red tides. With the acc...

AI Technical Summary

Problems solved by technology

However, if the water samples collected in the actual water body are transported and stored for a long time, there will be problems such as sample contamination and deterioration. Therefore, it is required to complete the sampling, filtration and chemical determination process on site, that is, in-situ measurement.
