Description

Technical Field

[0001] This application relates to the field of reaction equipment technology, and in particular to a reaction apparatus for protecting a pH meter. Background Technology

[0002] pH meters are core instruments used in industrial production, chemical experiments, and water quality monitoring for the precise measurement of solution acidity and alkalinity. Their electrodes, as key sensing components, directly determine the accuracy and stability of the measurement data. Using pH meters within reaction apparatus often faces the following technical challenges:

[0003] Electrodes are susceptible to contamination and physical damage: solid impurities in the reaction solution can easily adhere to the electrode surface, leading to increased measurement errors; liquid impact or particle collision during stirring can easily cause damage to the electrode glass bulb, shortening its service life.

[0004] The pH meter's overall protection is insufficient: the pH meter body is directly exposed to the reaction environment and is easily corroded by corrosive gases and splashing liquids; it lacks a stable installation structure, making the pH meter prone to displacement and affecting the effective contact between the electrode and the solution.

[0005] Maintaining electrode wettability is difficult: When the reaction interval or solution level is low, the electrode is easily dried out by exposure to air, resulting in a slow response in the next measurement, requiring repeated calibration and reducing experimental or production efficiency.

[0006] Inconvenient disassembly and maintenance of protective components: Most existing protective structures are integrated designs. When components such as protective nets and seals are damaged or blocked, they need to be completely disassembled and replaced, which is cumbersome and increases maintenance costs.

[0007] Chinese utility model patent CN220653710U discloses a pH meter protection device, including a protective cabinet, a cabinet door on the front of the protective cabinet, and a protective mechanism inside the protective cabinet. Limiting devices are provided on both sides of the protective mechanism, and a heat dissipation device is provided on the top of the protective cabinet. The limiting devices include adjusting mechanisms on both sides of the protective mechanism, with a limiting mechanism at one end of each adjusting mechanism. The heat dissipation device includes a heat dissipation mechanism on the top of the protective cabinet. This utility model utilizes a clockwise rotating adjusting screw to rotate the internal limiting frame, thereby pushing the limiting plate closer to the pH meter and engaging the limiting clamping plate to clamp the pH meter. The cooperation between a spring and a buffer plate effectively buffers the force generated during clamping, thus improving the lifespan of the pH meter and increasing the utilization efficiency of the protective device.

[0008] In existing technologies, pH meter electrodes are easily contaminated and damaged, overall protection is insufficient, electrode wettability is difficult to maintain, and maintenance of protective components is inconvenient. Therefore, there is an urgent need for a reaction device that combines multiple protections, stable fixation, and convenient maintenance functions to protect the pH meter. Utility Model Content

[0045] Specifically, during operation, the rotating motor 3 starts and drives the rotating shaft 11 to rotate, and the stirring blade 8 thoroughly stirs the liquid in the reaction equipment body 1 to ensure that the acidity and alkalinity of the solution are uniform, providing a representative sample for pH meter measurement.

[0046] In this embodiment, the first protective device includes a protective shell 7, a glass observation chamber 5, a second sealing plate 17, a second rubber seal 15, and a third rubber seal 16.
