One valve, the second valve and raffinate cup, drawing liquid pipeline is connected in the delivery pipe between first valve and the second valve, it is described
Drawing liquid pipeline connects sample connection, is provided with the 3rd valve on the drawing liquid pipeline at sample connection, and the sample connection connects
Syringe is connect, the syringe is provided with closure.
Preferably, the probe tube and delivery pipe are that transparent polyethylene material is made.
Preferably, the electrolyte bucket upper end side is provided with air inlet pipe, and air inlet pipe is provided with control valve.
The utility model has the advantage of：The utility model sampler, by setting the first valve, the second valve and the
It three valves, can be switched by the control of each valve, coordinate injection-tube to complete empty in probe tube and delivery pipe before electrolyte extracts
Gas is discharged, and reduces the possibility with air contact in electrolyte extraction process, and the electrolyte purity sampled in syringe is higher,
The probability that electrolyte absorbs outside moisture is smaller, and electrolyte sample is more representative, ensure that electrolyte moisture detects
Accuracy.
Further, probe tube and delivery pipe are that transparent polyethylene material is made, it can be seen that electrolyte in sampling process
Mobility status, be advantageous to control opening and closing and the syringe pump drainage of each valve, the air inlet pipe of electrolyte bucket upper end side is set, electricity
When solution liquid bucket electrolyte inside is extracted generation negative pressure, protective gas can be filled with time and carries out ftercompction, is advantageous to the suitable of electrolyte
Profit sampling.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Accompanying drawing in type embodiment, the technical scheme in the embodiment of the utility model is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model part of the embodiment, rather than whole embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, is belonged to
The scope of the utility model protection.
As shown in figure 1, a kind of electrolyte sampler, including electrolyte bucket 1, probe tube 2, ready-packaged joint 3 and syringe
5, the bottom of electrolyte bucket 1, the other end of probe tube 2 connection ready-packaged joint 3 are stretched into described one end of probe tube 2, and the ready-packaged joint 3 leads to
Cross delivery pipe 9 and be sequentially connected the first valve 6, the second valve 7 and raffinate cup 12, between the valve 7 of the first valve 6 and second
Drawing liquid pipeline 11 is connected in delivery pipe, the drawing liquid pipeline 11 connects sample connection 4, connect on the drawing liquid pipeline 11 close to sampling
The 3rd valve 8 is provided with first 4, the sample connection 4 connects syringe 5, and the syringe is provided with closure 10, the electrolysis
The upper end side of liquid bucket 1 is provided with air inlet pipe 14.
The probe tube 2 and delivery pipe 9 are that transparent polyethylene material is made.
The air inlet pipe 14 is provided with control valve 13.
When the utility model is specifically used, the syringe needle of syringe is stretched into sample connection, opens the first valve and the 3rd
Valve, close the second valve, pull syringe, the air in delivery pipe between the first valve and ready-packaged joint and in probe tube
Device extraction is injected, electrolyte is also begun to ramp up with pipeline, when liquid to be electrolysed reaches the first valve, closes the first valve, after
Continuous pull syringe, air in the connecting line between the first valve, the second valve and the 3rd valve is continued to be evacuated to syringe,
After taking out air, the 3rd valve is closed, syringe needle is removed in exhaustjet device after air from ready-packaged joint, connected again
It is connected on sample connection, is again turned on the first valve and the 3rd valve and twitches syringe sampling, after sampling terminates, by closure
Syringe needle is covered, closes the first valve and the 3rd valve, and removes syringe, opens the second valve by delivery pipe and drawing liquid
