Fixation protection apparatus for acidity meter electrode rods

Abstract

A fixed protection device for the electrode rod of the acidity meter, including a three-way pipe, the two ends of the main pipe of the three-way pipe are provided with bent pipes, the bent pipe is provided with a fixed section connection, and a fixed plate is provided in the opening of the branch pipe of the three-way pipe , the fixed plate is pierced with a protective sheath layer, and the electrode rod of the acidity meter extends into the tee pipe through the protective sheath layer; the fixed section of the tee pipe at both ends of the main pipe is provided with a flange plate, and the tee pipe passes through the flange The plate is fixed on the material tube. The two ends of the main pipe of the three-way pipe are provided with electromagnetic valves. A trachea is also arranged on the three-way pipe, and the air pipe communicates with the three-way pipe and the outside world. The branch pipe of the three-way pipe is also fixed with a threaded pipe, the threaded pipe is provided with internal threads, the electrode rod of the acidity meter is provided with external threads, and the part of the electrode rod of the acidity meter located outside the three-way pipe is connected with the threaded pipe through threads. By adopting the above structure, the electrode rod of the acidity meter can be effectively protected, the damage and replacement of components can be reduced, and the operating rate can be improved while saving costs.

Description

technical field [0001] The invention relates to the field of material pH detection in chemical production, in particular to a fixing protection device for an electrode rod of a pH meter. Background technique [0002] In the production practice of phosphorus flame retardants, the electrodes of the acidity meter for automatic detection of pH value are frequently used. Due to the material characteristics, the connection nut and screw rod of the pH electrode are severely corroded, and the connection device of the pH meter needs to be replaced frequently, which is not only expensive to replace, but also time-consuming and labor-intensive. , affecting the driving rate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fixed protection device for the electrode rod of the acidity meter, which can effectively protect the electrode rod of the acidity meter, reduce damage and replacement of parts, save costs and improve the...
