The PH value detector is an important detection tool for measuring and reflecting the pH value of a solution, and the working principle of the PH value detector is as follows: the body is a precision potentiometer which measures the PH of the solution by potentiometry. At present, no special on-line detection is available for the pH value on-line detection sampler for the reaction kettle in China, and no professional manufacturer produces the detection equipment in the domestic market. When present most enterprises need carry out the PH value to material in the reation kettle and detect, must take out the material that awaits measuring in the reation kettle then detect with the PH meter, and get the material mode and adopt manual simple and easy sampling device to absorb the material from the reation kettle basically. Therefore, the detection mode and the detection device are lagged behind and simple.
The existing detection device and detection mode can have the following defects and potential safety hazards in the process of detecting the pH value of a material in a reaction kettle: firstly, when a sample is extracted from a reaction kettle, a sampling device is simple, and the manual operation process is complicated; secondly, the samples are taken out and then put into a reagent bottle to be detected by a PH meter, and some samples may react with air in the detection process to influence the detection precision; thirdly, when the process requirement requires that the pH value of the materials in the reaction kettle is discontinuously or continuously monitored in real time, repeated sampling detection can be performed for many times, and the efficiency is low.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a PH value on-line measuring reation kettle sampler to solve current detection device and detect the problem that the mode used to exist in reation kettle interior material PH value testing process.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a PH value on-line measuring reation kettle sampler, includes the sampling tube, the bottom and the insert tube intercommunication of sampling tube, the insert tube stretches into reation kettle, sampling tube and diaphragm pump intercommunication, sampling tube and PH meter intercommunication, be equipped with the second valve between sampling tube and the insert tube, be equipped with flange between second valve and the insert tube, third valve and fourth valve are installed to flange's both sides, fourth valve and fifth valve intercommunication, fifth valve and third valve communicate with the sampling bottle respectively, the fifth valve is connected with the one end of back flow, the other end and the diaphragm pump intercommunication of back flow.
Preferably, the sampling tube is transparent and visible.
Preferably, the sampling pipe is further provided with a first valve, and the first valve is connected with the nitrogen pipeline.
Compared with the prior art, the beneficial effects of the utility model are that: the method has the advantages that the operation is convenient, the PH value detection process is safe, rapid and reliable, the detection process is closed and has no leakage, the process is not required to be stopped, and the material can be taken out for detailed assay while the online detection function is realized; the sampling tube is transparent and visible, and the physical state of the detected material can be clearly observed while detection is carried out; materials in the reaction kettle are fully circularly mixed before each detection, the detection result is real and accurate and representative, and the production can be better guided.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: the utility model provides a PH value on-line measuring reation kettle sampler, including sampling tube 1, the bottom and the inserted tube 2 intercommunication of sampling tube 1, inserted tube 2 stretches into reation kettle 10, sampling tube 1 and diaphragm pump 8 intercommunication, sampling tube 1 and PH meter intercommunication, PH meter interface in this embodiment is strong in general match, the installation is dismantled conveniently, applicable PH meter in most brand model on the market, be equipped with second valve 4 between sampling tube 1 and the inserted tube 2, be equipped with flange between second valve 4 and the inserted tube 2, third valve 5 and fourth valve 6 are installed to flange's both sides, fourth valve 6 and fifth valve 7 intercommunication, fifth valve 7 and third valve 5 communicate with sampling bottle 9 respectively, fifth valve 7 is connected with the one end of back flow, the other end and the diaphragm pump 8 intercommunication of back flow. In the testing process, need not the technology and parks, also need not to open the cauldron mouth, convenient operation, the airtight nothing of testing process leaks, and the testing process is safe, quick, reliable, does not need the technology to park, has the on-line measuring function, and this application still is connected with sampling bottle 9 simultaneously, also can take out the material and carry out detailed chemical examination.
