Although ordinary PH meter instrument detects can direct measurement material pH value, has avoided operating personnel direct contact, when the reaction material has the suspended solid, the easy adhesion material of PH meter for measuring result is inaccurate, can not in time reflect out the pH value of system.
Therefore, those skilled in the art have been devoted to developing a PH detection device that can rapidly and effectively detect PH and avoid direct contact between the operator and the hazardous chemical.
SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned defect of prior art, the utility model aims to solve the technical problem that a PH value detection device is provided, can quick effectual detection PH value, and avoid operating personnel direct and dangerous chemical contact.
In order to achieve the above object, the utility model provides a PH value detection device, including the PH meter, the PH meter is installed in the solution cabin, the solution cabin is through first connecting pipe and reation kettle intercommunication, the solution cabin still looks a section of thick bamboo with the observation and communicates with each other, it looks a section of thick bamboo through second connecting pipe and evacuation system intercommunication to observe. And extracting the solution in the reaction kettle by vacuumizing, wherein the observation vision cylinder is used for checking whether the PH meter is completely immersed in the material, so that the detection accuracy is ensured.
Further, the PH meter is connected with a PH value display device. The PH value display device is used for displaying the PH value of the detection solution, and is simple and visual.
Further, the second connecting pipe is connected with an industrial water pipe and a compressed air pipe. Industrial water and compressed air are used for washing the solution cabin and the PH meter, and the corrosion of the solution cabin and the PH meter caused by materials is avoided.
Furthermore, a first valve and a second valve are respectively arranged on the industrial water pipe and the compressed air pipe.
Furthermore, the first connecting pipe is connected with a waste liquid pipe, and a third valve is installed on the waste liquid pipe.
Furthermore, a fourth valve is installed on the first connecting pipe, and a fifth valve is also installed on the vacuum pumping system pipeline.
