Embodiment 1

[0049] Such as figure 1 , 2 , 3, 6, and 7, an automatic centrifugal pretreatment device for water quality detection, including a casing 1, a centrifuge 2, a water inlet pipe 3, a water outlet pipe 4, a centrifugal cup 5, a left cover door 6, and a left power rod 7 , left chute 8, right cover door 9, right power lever 10, right chute 11, down chute 12, left cylinder 13, right cylinder 14, connecting pipe 15, position sensor 16, rotating plate 17, pulley 18, Rotating machine 19, lifter 20, fixed plate 21, lifting plate 22, height sensor 23, water outlet pump 24 and water inlet pump 25, inside the shell 1, the water inlet pipe 3, the water outlet pipe 4, the left power rod 7, and the left chute are fixed by bolts 8. Right cover door 9, right power rod 10, right chute 11, left cylinder 13, right cylinder 14 and fixed plate 21, water inlet pipe 3 communicates with water inlet pump 25 through pipelines, and water inlet pump 25 is connected in parallel with metering cup water inlet ...

Embodiment 2

[0052] This embodiment is basically the same as Embodiment 1, the difference is: as figure 1 , 4 , shown in 6, in embodiment 2, cancel left power bar 7, left chute 8, right power bar 10, right chute 11, down chute 12, left cylinder 13 and right cylinder 14, be fixed on shell 1 bottom instead Left rotary motor 26 and right rotary motor 27 at two ends, left rotary motor 26, right rotary motor 27 are connected with left cover door 6, right cover door 9 by rotating shaft, during work, left rotary motor 26 and right rotary motor 27 are driven by rotation The left cover door 6 and the right cover door 9 rotate.

Embodiment 3

[0054] This embodiment is basically the same as Embodiment 1, the difference is: as figure 1 , 5 , shown in 6, in embodiment 2, cancel left power bar 7, left chute 8, right power bar 10, right chute 11, down chute 12, left cylinder 13 and right cylinder 14, be fixed on shell 1 bottom instead Rotating motor 28 and chute 29, rotating motor 28 is connected with left cover door 6 by rotating shaft, and left cover door 6 is connected with right cover door 9 by rotating shaft, and right cover door 9 other ends are connected chute 29 by pulley, during work, The rotation of the rotating motor 28 drives the left cover door 6 to rotate and then the right cover door 9 moves linearly along the chute 29 .

Abstract

The invention discloses an automatic centrifugal pretreatment device for water quality detection, comprising a casing, a source water pipe, a tap water pipe, a waste water pipe, a sample retention pipe, a water inlet pump, a drain pump, a source water inlet valve, a tap water inlet valve, waste water Valve, sample retention valve, filling device, centrifugal pipeline, rotary mechanism, centrifugal mechanism, controller, connecting pipe and waste water pipe; It is poured into the centrifuge for centrifugation, and the separated centrifugal water is automatically drawn out through the connecting pipe for analysis, and then the waste water is discharged to realize the automatic water treatment of the entire source water, which is simple and efficient.

Description

technical field [0001] The invention belongs to the field of water quality detection instruments, in particular to an automatic centrifugal pretreatment device and method for water quality detection. Background technique [0002] The mainstream brand of total phosphorus automatic monitoring instrument used by the automatic water quality monitoring station generally adopts the ammonium molybdate spectrophotometric method for the analysis principle, which is consistent with the manual monitoring method, but there are certain differences between the digestion process and the water sample pretreatment process and the laboratory method . The difference in the process leads to the difference in the test results, especially when the turbidity in the water is high, the automatic monitoring results of parameters such as total phosphorus will be obviously interfered by the turbidity, and generally have a positive correlation. Therefore, there is a lack of a pretreatment device that c...
