Description

Technical Field

[0001] The utility model belongs to the technical field of protection devices, and in particular relates to a simple protection device for an industrial pH meter. Background Art

[0002] Industrial pH meters are widely used in chemical industry, metallurgy, sewage treatment, pharmaceuticals, fermentation, tap water and other fields due to their high measurement accuracy, sensitive response, accurate reading and simple operation. They are special instruments for continuous digital display of pH value.

[0003] A simple protection device for an industrial pH meter is disclosed in the utility model patent with the patent authorization announcement number CN205157481U, which mainly includes an outer protective sleeve, an inner protective sleeve and a pH meter sealing and fixing device, wherein the outer protective sleeve can keep the pH meter electrode measuring end moist for a long time to prevent the electrode from oxidation and air drying, and the matching use of the inner protective sleeve and the pH meter sealing and fixing device can further prevent the pH meter measuring electrode from contacting the air and oxidation, as well as impact damage during use, and at the same time can prevent the electrode signal transmission line from contacting the solution to be tested and being corroded, and the combined effect of the three can greatly increase the service life of the pH meter; in addition, the rectangular opening, the infusion tube and the three-way valve on the infusion tube can realize long-term continuous measurement of the pH meter, and can improve the stability and reliability of the measurement. The device has a simple structure, is economical and practical, and can be widely used in the protection of pH meters in various industrial fields.

[0004] However, the existing simple protection device of the industrial pH meter also has certain shortcomings. First, although the simple protection device of the existing industrial pH meter uses a threaded connection to fix the electrode protection cover and the end plate, due to the influence of external factors such as impact and vibration, long-term use may cause the electrode protection cover to vibrate and loosen;

[0005] Secondly, the simple protection device of the existing industrial pH meter simply sets liquid inlet micropores on the surface of the electrode protection cover for the normal circulation of the solution and to facilitate the subsequent electrode head detection. Due to the influence of factors such as impurities, long-term use will cause the liquid inlet micropores to be blocked, thereby causing the circulation of the solution to become weakened. Summary of the invention

[0006] The utility model aims to provide a simple protection device for an industrial pH meter, which solves the problem that the electrode protection cover may become loose due to vibration after long-term use in the simple protection device of the existing industrial pH meter, although the electrode protection cover is fixed to the end plate by a threaded connection, due to the influence of external factors such as impact and vibration; and solves the problem that the simple protection device of the existing industrial pH meter simply sets liquid inlet micropores on the surface of the electrode protection cover for the normal circulation of the solution, which is convenient for subsequent electrode head detection, and due to the influence of factors such as impurities, the liquid inlet micropores may be blocked after long-term use, thereby weakening the circulation of the solution.
