For the ease of illustrating the technical scheme of the utility model; The liquid sampling analytical equipment that provides among the utility model embodiment; Be used for the detection of the potential of hydrogen of wet etching equipment etching liquid, but the scope of application of the liquid sampling analytical equipment that provides among the utility model embodiment is not limited thereto.
As shown in Figure 2, in the utility model embodiment, the liquid sampling analytical equipment is connected with the container of ccontaining testing liquid; Promptly be connected with the etching liquid storage chamber 16 of ccontaining etching liquid, promptly input duct 1 one ends are connected with etching liquid storage chamber 16, at this moment; Valve control device is controlled first valve 2 and is closed; Be that etching liquid (dash area illustrates among the figure) can't pass through first valve 2, simultaneously, control second valve 8 and 12 unlatchings of the 3rd valve; The 4th valve 15 is closed, and makes the air pressure of analyzing in the chamber 4 equal atmospheric pressure.
As shown in Figure 3, because the pressure in the etching liquid storage chamber 16 is greater than atmospheric pressure, so when valve control device is controlled 2 unlatchings of first valve; Etching liquid (dash area illustrates among the figure) promptly prolongs input duct 1 and gets into analysis chamber 4 and induction pipe 9; Because the liquid level of analyzing in chamber 4 and the induction pipe 9 is the height such as grade, so when the liquid level of etching liquid rose to the 3rd level sensor 10 places, the liquid levels of analyzing in the chamber 4 had also reached desirable measuring height; At this moment; After the 3rd level sensor 10 is sensed liquid level signal is transferred to valve control device, valve control device is controlled first valve 2, second valve 8 and the 3rd valve 12 immediately and is closed, and makes etching liquid stop to continue to get into and analyzes chamber 4; Closing of second valve 8 is too high in order to prevent the etching liquid liquid level; Cause etching liquid to spill in the gas exhaust duct 11, second level sensor 13 that is provided with on the gas exhaust duct 11 simultaneously also is in order to prevent that etching liquid from spilling in the gas exhaust duct 11, if when etching liquid spills in the gas exhaust duct 11; Second level sensor 13 can be sensed etching liquid; And alerting signal is transferred to valve control device, whether the latter checks first valve and second valve to close once more, prevent etching liquid continue overflow.
After etching liquid get into to be analyzed chamber 4 and first valve 2 and closed, analytical equipment began etching liquid is detected, i.e. the potential of hydrogen of inductor 5 induction etching liquids; And the data transmission that will describe the etching liquid potential of hydrogen is given potential of hydrogen analytical equipment 6; 6 pairs of these data of potential of hydrogen analytical equipment are analyzed, and the analysis result signal is transferred to display device 7, and display device 7 changes into image with this signal; Make the operating personnel can be after the potential of hydrogen data of observing etching liquid intuitively; If analysis result is unusual, potential of hydrogen analytical equipment 6 can be transferred to abnormal signal the supervisory system of wet etching equipment, and wet etching equipment will be reported to the police and is out of service; If analysis result is normal; Potential of hydrogen analytical equipment 6 can be transferred to valve control device with corresponding signal, after valve control device is received signal, will control the 4th valve 15, second valve 8 and 2 unlatchings of first valve.
After the 4th valve 15 is opened; The pressue device that is connected with admission line 14 begins to analyzing pressurization in the chamber 4; The pressure of analyzing in the chamber 4 will constantly raise; Pressure in analyzing chamber 4 is during greater than the pressure etching liquid storage chamber 16 in, and analysis chamber 4 interior etching liquids will pass back in the etching liquid storage chamber 16 gradually.
As shown in Figure 4; When etching liquid (dash area illustrates among the figure) liquid level is lower than first level sensor 3 on the input duct 1, i.e. first level sensor, 3 inductions are during less than liquid level, and first level sensor 3 is transferred to valve control device with signal; After valve control device is received signal; To control first valve 2 and the 4th valve 15 is closed, and arrive this, primary sample is analyzed and is finished.
Instantly after sub-sampling analysis began, the 3rd valve 12 was opened, and the gas that the 3rd valve 12 is opened in the post analysis chamber 4 will prolong gas exhaust duct 11 discharges, make the pressure of analyzing in the chamber 4 return to atmospheric pressure gradually, and process afterwards is the same.
First valve, second valve, the 3rd valve and the 4th valve used among the utility model embodiment all adopt pneumatic valve.
The liquid sampling analytical equipment that the utility model embodiment provides; Utilize the opening and closing of level sensor by-pass valve control; Thereby make between the container of the inner and ccontaining testing liquid of liquid sampling analytical equipment and produce pressure reduction; Realization is to the sampling and analysing of testing liquid; And the liquid sampling analytical equipment that the utility model embodiment provides is set directly on the container of ccontaining testing liquid, makes testing liquid from the time shortening that the whole process that is sampled to analysis experiences, thereby makes the potential of hydrogen of testing liquid promptly and accurately analyzed and to inform the production operation personnel.
The foregoing description provides only is the concrete a kind of scheme used of the utility model, and this analytical equipment not only can be analyzed liquid in concrete the application, also can be used to analyze the colloid that can flow, suspension etc.
