[0002] Environmental monitoring refers to the activities of environmental monitoring agencies to monitor and measure the environmental quality status. Environmental monitoring is to determine the environmental pollution status and the level of environmental quality by monitoring and measuring the indicators that reflect the environmental quality. The content of environmental monitoring mainly includes the monitoring of physical indicators, the monitoring of chemical indicators and the monitoring of ecosystems. Environmental monitoring is an indispensable basic work for environmental protection. In environmental monitoring work, water samples often need to be filtered, and a filtering device is required for filtering water samples.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1-5 As shown, the utility model provides an environmental detection water sample filtering device, including a filtering device body 1, which is suitable for water sample detection. The filtering device body 1 includes a filtering box 2, a supporting bracket 3 is fixedly installed on the top of the filtering box 2, and supporting legs 4 are welded on all sides of the bottom end of the filtering box 2. A filtering unit is arranged inside the filtering box 2, and an anti-blocking unit is arranged on the top of the filtering unit. The filtering unit includes a water outlet hopper 21 fixedly installed on the output end at the bottom of the filtering box 2, and an annular frame 22 is arranged on the bottom end of the inner wall of the filtering box 2. A filter screen 23 is fixedly installed on the inner wall of the frame 22, a driving motor 31 is fixedly installed on the top of the supporting bracket 3, a driving rod 32 is fixedly installed on the output end of the driving motor 31, the other end of the driving rod 32 extends to the inner bottom end of the filter box 2, a rotating ring 33 is fixedly sleeved on the top of the outer surface of the driving rod 32, connecting cross bars 34 are fixedly installed on the outer surfaces of the rotating ring 33, a scraper vertical plate 35 is fixedly installed on the other end of the connecting cross bar 34, and the scraper vertical plate 35 is closely connected to the inner wall of the filter box 2.

[0026] Furthermore, the water sample to be tested is introduced into the interior of the filter box 2 and filtered by the filter mesh 23. At the same time, the output end of the driving motor 31 drives the driving rod 32 to rotate at a uniform speed, thereby prompting the connecting cross bar 34 to rotate and stir inside the liquid, thereby promoting the fluidity of the liquid and the filtration rate. When the connecting cross bar 34 rotates, it drives the scraper vertical plate 35 to rotate and make it rotate and scrape on the inner wall of the filter box 2 to prevent scale from sticking.

[0027] Example 2

[0028] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the anti-blocking unit includes an abutment block 25 fixedly installed on the inner wall of the annular frame 22 around the top of the filter screen 23, and through holes 24 are opened on the top of the annular frame 22. Fixed blocks 26 are fixedly installed on the bottom of the inner wall of the filter box 2 around the bottom, and a fixed vertical rod 27 is fixedly installed on the top of the fixed block 26. A reset spring 28 is movably sleeved on the outer surface of the fixed vertical rod 27, and the other end of the fixed vertical rod 27 passes through the inside of the through hole 24. A rotating ring 2 36 is fixedly sleeved on the bottom end of the driving rod 32, and dust plates 37 are fixedly installed on the outer surfaces of the rotating ring 2 36 around the top, and the dust plates 37 are rotatably fitted on the top outer surface of the filter screen 23.

[0029] Furthermore, the rotation of the drive rod 32 simultaneously drives the rotating ring 23 to rotate accordingly, and the rotating ring 23 drives the dust-flicking plate 37 to rotate on the top of the filter screen 23 to clean the impurities attached to the filter screen 23 and dredge the mesh. When the dust-flicking plate 37 rotates and overlaps with the resistance block 25, the resistance block 25 will be pushed downward. At this time, the resistance block 25 drives the annular frame 22 to slide down on the outer surface of the fixed vertical rod 27 and squeeze the reset spring 28. When the dust-flicking plate 37 and the resistance block 25 are rotated to move apart, the filter screen 23 rebounds and resets under the elastic reverse thrust of the reset spring 28, thereby reciprocating up and down, promoting the shaking of the filter screen 23, further promoting the filtration rate, and preventing the mesh from being blocked.

[0030] The following is a detailed description of the working principle of the environmental testing water sample filtration device.

[0031] like Figure 1-5As shown, when in use, the water sample to be tested is introduced into the interior of the filter box 2, and the filter screen 23 is used to filter it. At the same time, the output end of the driving motor 31 drives the driving rod 32 to rotate at a uniform speed, thereby prompting the connecting cross bar 34 to rotate and stir the liquid, thereby promoting the fluidity of the liquid and the filtration rate. When the connecting cross bar 34 rotates, it drives the scraper vertical plate 35 to rotate and rotate to scrape the inner wall of the filter box 2 to prevent scale from sticking. At the same time, the rotation of the driving rod 32 drives the rotating ring 2 36 to rotate, and the rotating ring 2 36 drives the dust removal plate 3 7 rotates on the top of the filter screen 23 to clean the impurities attached to the filter screen 23 and dredge the mesh. When the dust-flicking plate 37 rotates and overlaps with the abutment block 25, the abutment block 25 is pushed downward. At this time, the abutment block 25 drives the annular frame 22 to slide down on the outer surface of the fixed vertical rod 27 and squeeze the return spring 28. When the dust-flicking plate 37 and the abutment block 25 are rotated so as to move away from each other, the filter screen 23 rebounds and resets under the elastic reverse thrust of the return spring 28, thereby reciprocating up and down, promoting the shaking of the filter screen 23, further promoting the filtering rate, and preventing the mesh from being blocked.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
