Description

Technical Field

[0001] The utility model provides a marine water quality monitoring sample filtering device, belonging to the technical field of marine water quality monitoring. Background Art

[0002] Before monitoring the ocean water quality, it is necessary to sample the water quality first. In order to achieve the precision and accuracy of water quality monitoring, it is often necessary to sample ocean water at different locations and depths. However, the ocean water in some areas contains a large amount of suspended matter, impurities, algae, etc., which are present in the sample water together with these substances when sampling. When testing ocean water samples, the presence of these suspended matter and impurities will affect the detection effect, so it is often necessary to perform preliminary filtration treatment on the sample water quality.

[0003] Existing filtering devices for marine water quality monitoring samples often use a double filtering method, first using a filter to filter out large particles, impurities, and algae, and then finely filtering them. After long-term use, the filter mesh will be clogged with some impurities, affecting the normal operation of the filter. The filter is often inside the filtering device, and when cleaning the filter, it is often necessary to remove the filtering device and then clean it, which is time-consuming and labor-intensive, affecting its use. In response to the above problems, a filtering device is needed that can facilitate the rapid removal of impurities in the filter mesh to avoid blockage that affects the filtering effect.

A sealing gasket is provided on the sealing plate 5 to increase the sealing performance of the connection between the sealing plate 5 and the filter box 1 .

[0032] Principle of the utility model

[0033] When in use, an ocean water sample is added from the water inlet pipe 2, passes through the filter holes 11 on the fixed plate 8 to filter out large particles, suspended matter, algae and other impurities, and then enters the water blocking plate 17 on the sliding plate 7, and then falls onto the support plate 15 from the through hole 18 on the sliding plate 7. After secondary filtration by the filter membrane 14, it flows from the drainage hole 19 to the bottom of the filter box 1, and finally flows out from the outlet pipe 3.

[0034] When too many impurities are stuck in the filter hole 11 for a long time and the filtering efficiency is affected, it needs to be cleaned. When the filter box 1 is not working, the dredging motor 20 is started. Driven by the movable plate 21, the sliding plate 7 moves upward to drive the dredging rod 12 to be inserted into the filter hole 11, so that all the impurities stuck in the filter hole 11 are poked to the surface of the fixed plate 8. Under the condition that the dredging rod 12 is ensured to be located in the filter hole 11, the fixing screw 13 is screwed out, and the sealing plate 5 is pulled outward. Driven by the connecting rod 10, the cleaning plate 9 scrapes on the surface of the fixed plate 8, and the impurities originally existing on the surface of the fixed plate 8 and cleaned out from the filter hole 11 are scraped into the storage box 6. After scraping, the sealing plate 5 is re-fixed on the filter box 1, and the dredging motor 20 is reversed to drive the sliding plate 7 and the dredging rod 12 to return to their original positions. Therefore, the present application is quick and convenient for clearing out the impurities stuck in the filter hole 11, without disassembling the filtering structure.
