Description
Technical field
The utility model belongs to bulk pharmaceutical chemicals and prepares online measuring technique field, and in particular to one kind being used to prepare 1,2- rings penta
The pH on-line measuring devices of two carbimides.
Background technology
PH detections are essential to the detection of liquid acid-base value in the fields such as chemical reaction, environment measuring；It is preparing
In 1,2- ring, penta 2 carbimide detection process, the surface of pH electrodes can be acted on by detected liquid, gradually form one layer of dirt
The film that object is constituted；This layer film hinders the infiltration of the ion pair glass electrode in liquid, and pH electrodes just can not again carry out just
Normal detection.
Traditional solution is to rely on manually to remove pH electrodes from device, with hairbrush to the table of glass electrode
Face is cleaned, and dirt is removed；The shortcomings that conventional method is：PH value narrow application range can only detect acid or alkali or organism
System, how much size and inventory to reaction kettle are distinctly claimed；Calibration is inconvenient, needs the dismounting school of 2-3 people 1 hour or more
Quasi- can not calibrate in operational process, and testing result is inaccurate；PH is caused to drift about package probe in sticky system operational process,
It can not solve；Expensive, accessory is not easy to replace.
Utility model content
The utility model in view of the above problems, provides the pH that one kind being used to prepare 1,2- rings, penta 2 carbimide
On-line measuring device, solving the technical solution of technical problem is：
It is used to prepare the pH on-line measuring devices of 1,2- rings, penta 2 carbimide, which is characterized in that including reaction kettle, detection
Pond, pH detecting electrodes, pH display screens, circulation pipe and circulating pump, the reaction kettle top and bottom end are connected separately with circulation pipe, follow
Circulating pump and detection cell are installed, circulating pump can be pumped out the feed liquid in reaction kettle by bottom, be returned through top circulation pipe on endless tube
Reaction kettle is flowed into, fixed in detection cell there are two pH detecting electrodes, and each pH detecting electrodes top is connected with signal wire, signal
The line other end is connected with pH display screens.
Preferably, valve A is installed on the circulation pipe on the close reaction kettle top, the cycle close to reaction kettle bottom end
Valve B is installed on pipe.
Preferably, it is connected with power supply in the pH display screens.
Preferably, the detection cell is equipped with fixed frame, can fix pH detecting electrodes.
The utility model has the advantages that：
1.pH values are applied widely：Detectable acid, alkalinity or organic solvent etc., can be used arbitrary kettle and arbitrary volume.
2. calibration is convenient：1 people 5min can realize calibration, and calibration can be taken out at any time in operational process.
3. accuracy is high：A calibration can be taken out at any time using double pH detection probes, in operational process, accuracy is high.
4. at low cost：Probe can be replaced at any time, and overall tolerability is good, cheap.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In figure, 1- reaction kettles, 2- detection cells, 21- fixed frames, 3-pH detecting electrodes, 4-pH display screens, 5- circulation pipes, 51-
Valve A, 52- valve B, 6- circulating pump.
Specific implementation mode
Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model is clearly and completely described.
It is used to prepare the pH on-line measuring devices of 1,2- rings, penta 2 carbimide, which is characterized in that including reaction kettle 1, inspection
Pond 2, pH detecting electrodes 3, pH display screens 4, circulation pipe 5 and circulating pump 6,1 top of the reaction kettle and bottom end is surveyed to be connected separately with
Circulation pipe 5 is equipped with circulating pump 6 and detection cell 2 on circulation pipe 5, and circulating pump 6 can be pumped out the feed liquid in reaction kettle 1 by bottom,
Reaction kettle 1 is passed back into through top circulation pipe 5, and fixed in detection cell 2 there are two pH detecting electrodes 3, each 3 tops of pH detecting electrodes
It is all connected with signal wire, the signal wire other end is connected with pH display screens 4.
Preferably, valve A51 is installed on the circulation pipe 5 on 1 top of the close reaction kettle, close to 1 bottom end of reaction kettle
Circulation pipe 5 on valve B52 is installed.
Preferably, it is connected with power supply in the pH display screens 4.
Preferably, the detection cell 2 is equipped with fixed frame 21, can fix pH detecting electrodes 3, prevent from drifting about.
When preparing the detection of 1,2- rings, penta 2 carbimide, valve A51, valve B52 and circulating pump 6 are opened, reaction kettle 1
Interior feed liquid is pumped by circulating pump 6 in detection cell 2, and two pH detecting electrodes 3 are separately fixed in detection cell 2, prevent from drifting about；
PH display screens 4 can show pH numerical value；When needing to calibrate or clear up probe, a calibration or clear can be taken out in operational process at any time
Reason probe, pH value accuracy in detection are high.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
It is confined to this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.
