Direction.
As shown in Figs. 1-2, first embodiment of the invention: a kind of water quality on-line sampling device, including cabinet 1,1 inside of cabinet
Equipped with the baffle 2 being connected respectively with the upper wall of the two lateral walls of cabinet 1 and cabinet 1, the bottom surface of baffle 2 and cabinet 1 is equipped with stream
The inner cavity of cabinet 1 is divided into gas-liquid separation chamber 11 and sampler chamber 12 by road gap 21, baffle 2, in gas-liquid separation chamber 11 with 2 phase of baffle
Pair 1 side wall lower ends of cabinet be equipped with sample feeding pipe 3, the nozzle of sample feeding pipe 3 blocks along its axial direction by baffle 2, gas-liquid separation chamber
It is additionally provided with overflow pipe 4 on 1 side wall of cabinet in 11,1 side wall of cabinet in sampler chamber 12 is equipped with sample outlet pipe 5.
The plane perpendicular of baffle 2 and cabinet 1, the nozzle lower end of sample feeding pipe 3 are lower than the lower end of baffle 2, the nozzle of sample feeding pipe 3
Along its axial direction by 2 partial occlusion of baffle.The water sample entered from sample feeding pipe 3 first passes through filtering, filters out large granular impurity, filters
Water sample to be detected afterwards enters from sample feeding pipe 3, and water sample encounters the blocking of baffle 2 after the inflow of sample feeding pipe 3, and flow path is divided into gas-liquid
The flow path in 21 direction of flow path and flow path gap in separation chamber direction.The water sample and baffle 2 entered due to sample feeding pipe 3 is hit, water sample
Direction suddenly change, the big bubble of buoyancy will flow up, and bubble largely flows to gas-liquid separation chamber 11 and through 4 row of overflow pipe
Out, reduce bubble and flow into sampler chamber 12 from flow path gap 21, the water sample bubbles of sampler chamber 12 are flowed into from flow path gap 21
Seldom, 1 upper wall of cabinet in sampler chamber 12 is equipped with venthole 14, and venthole 14 is for being discharged into gas few in sampler chamber 12
Bubble.When the water sample in gas-liquid separation chamber 11 is higher than overflow pipe 4, water sample and bubble can be discharged by overflow pipe 4, overflow pipe
It is also equipped with shut-off valve (being not drawn into figure) on 4, facilitates the care and maintenance of cabinet 1.The nozzle height of sample outlet pipe 5 is greater than sample introduction
The nozzle height of pipe 3；When being that water level is gradually increased in sampler chamber 12, when reaching the height of sample outlet pipe 5, it is discharged in sample outlet pipe 5
Water sample is used for the water source to be checked of detection device.Since the water level in sampler chamber 12 is gradually increased, so being flowed out from sample outlet pipe 5
Water sample be circulation water sample, the water sample in sampler chamber 12 is circulation always, will not generate stagnant water.The nozzle height of overflow pipe 4
Greater than the nozzle height of sample outlet pipe 5, when the water sample in gas-liquid separation chamber 11 is higher than overflow pipe 4, water sample and bubble pass through overflow
Pipe 4 is discharged.When the water sample in sampler chamber 12 reaches the height of sample outlet pipe 5, the water sample of bubble-free is discharged from sample outlet pipe 5, provides
It is detected to water quality online analyzer as sample.
1 bottom surface of cabinet in sampler chamber 12 is equipped with evacuated tube 13, and evacuated tube 13 is equipped with shut-off valve (being not drawn into figure).Row
Blank pipe 13 is used for the water sample being discharged in cabinet 1, since sample feeding pipe 3 is lower than sample outlet pipe 5, contains from the water sample that sample feeding pipe 3 enters
Partial impurities be deposited on the lower part of sampler chamber 12, the water sample being discharged from sample outlet pipe 5 does not have bubble and no impurity, passes through emptying
Pipe 13 these impurity can be discharged, convenient for the cleaning, maintenance and maintenance of cabinet 1.
According to actual needs, the mountable shut-off valve of sample feeding pipe 3, sample outlet pipe 5, to facilitate disengaging and the cabinet 1 of water sample
Maintenance and maintenance.
As shown in figure 3, the difference of the second embodiment of the present invention and first embodiment is, the nozzle lower end of sample feeding pipe 3
Contour with the lower end of baffle 2, the nozzle of sample feeding pipe 3 is blocked along its axial direction by baffle 2 completely.
The water sample and baffle 2 that the sample feeding pipe 3 of the present embodiment enters are hit, water sample direction suddenly change, the big bubble of buoyancy
Will flow up, water sample a part flow into 3 nozzle of sample feeding pipe above gas-liquid separation chamber 11, water sample another part then flow through into
Enter sampler chamber 12 from flow path gap 21 below the nozzle of sample pipe 3, the water sample bubbles flowed into sampler chamber 12 are less.
As shown in figure 4, the difference of the third embodiment of the present invention and first embodiment is, the lower end of baffle 2 close into
The axis angle of sample pipe 3 and baffle 2 and sample feeding pipe 3 is α, 75 ° of 90 ° of < α <, the baffle 2 of the present embodiment and the axis of sample feeding pipe 3
Preferably 80 ° of angle α.
Due to existing angle between the axial direction and baffle 2 of sample feeding pipe 3, the water sample that enters from sample feeding pipe 3 with gear
When plate 2 is hit, water sample is that helical form is presented to enter gas-liquid separation chamber 11 above 3 nozzle of sample feeding pipe, at this time the big bubble of buoyancy
It flows up, it is suppressed that bubble flows into sampler chamber 12 from flow path gap 21, which goes the better effect of bubble, from flow path gap
The water sample bubbles of 21 inflows are less, ensure that water quality on-line checking instrument when detecting to the requirement of water sample.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
