Description

Technical Field

[0001] This utility model relates to an industrial pH electrode structure, specifically a large-diameter flat film industrial pH electrode structure that is impact-resistant and wear-resistant. Background Technology

[0002] In some industrial processes, pH measurements may involve water samples with high flow rates and the presence of particulate matter. Conventional spherical or cylindrical pH glass bulbs may suffer from impact abrasion, leading to decreased electrode performance or even damage. Choosing a large-diameter, flat-film industrial pH electrode, with the sensitive membrane positioned 0.5 mm below the electrode casing, avoids the impact of water flow containing solid particles, effectively improving the lifespan of the glass membrane.

[0003] pH electrodes with flat membrane structures made of HA (hygroscopic HA) membrane material are suitable for online testing of many impactful and particulate solutions. Conventional flat membrane pH electrodes have higher membrane impedance compared to spherical or cylindrical glass bulbs, and HA membrane material also has higher membrane impedance than other membrane materials. Therefore, pH electrodes with flat membrane structures made of HA material have very high impedance. High impedance electrodes can lead to slow response and low sensitivity. This is why most manufacturers do not choose this electrode structure. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides a large-diameter flat membrane industrial pH electrode structure that is impact-resistant and wear-resistant. Based on a flat membrane structure using HA membrane material, a thicker, larger-diameter membrane structure is selected, effectively reducing membrane impedance while meeting the measurement requirements for the electrode structure. The electrode is internally fixed using a silicone rubber support, and employs an open liquid junction to effectively prevent clogging and maintain optimal electrode performance.

[0005] This utility model is achieved through the following technical solution: a large-diameter flat membrane industrial pH electrode structure that is impact-resistant and wear-resistant, comprising an electrode shell structure, an inner glass tube, a reference electrolyte, a silicone rubber support, a large-diameter flat membrane, an open liquid network section, an inner reference solution, an Ag / AgCl reference system, and a reference system, wherein the space between the electrode shell structure and the inner glass tube is filled with a reference electrolyte.

[0006] The silicone rubber bracket is fixedly connected inside the electrode housing structure to support and fix the glass tube inside the electrode;

[0007] The large-diameter flat membrane is connected to the lower end of the glass tube inside the electrode, serving as the measuring structure of the electrode.

[0008] The open liquid entanglement section is located at the lower end of the electrode housing structure;

[0009] The reference solution inside the electrode fills the interior of the glass tube inside the electrode and is connected to the Ag / AgCl reference system to form the reference system of the electrode.

[0010] As a preferred technical solution, the large-diameter flat membrane is made of HA membrane material and is manufactured into a large-diameter planar membrane structure through a thick film process, and is connected to the lower end of the glass tube inside the electrode.

[0011] As a preferred technical solution, the reference electrolyte between the electrode shell structure and the inner glass tube of the electrode is a gel or a solid polymer.

[0012] As a preferred technical solution, the open liquid winding section is sealed to the electrode housing structure through O-rings and epoxy resin.

[0013] As a preferred technical solution, the bulb diameter of the large-diameter flat membrane is 8mm, and the large-diameter flat membrane is 5mm lower than the electrode shell structure.

[0014] The beneficial effects of this utility model are: the industrial pH electrode with a large diameter flat membrane structure of this utility model, based on the use of HA membrane material flat membrane structure, selects a large diameter membrane structure, which effectively reduces membrane impedance while meeting the measurement requirements for electrode structure.

[0015] During the manufacturing process, the flat membrane structure is 5mm lower than the electrode shell, which can protect the electrode from damage when measuring water samples with high flow rates and containing particulate matter. The electrode is sealed with O-rings and epoxy resin and has an open liquid network section, which can effectively avoid clogging during water sample measurement. Attached Figure Description

[0020] like Figure 1 As shown, this utility model relates to a large-diameter flat membrane industrial pH electrode structure that is impact-resistant and wear-resistant, and is particularly suitable for pH measurement in industrial processes, especially when the water sample being measured has a high flow rate and contains particulate matter. The specific implementation of this electrode structure will be described in detail below.

[0021] A reference electrolyte 2, including but not limited to a gel or solid polymer, is filled between the electrode housing structure 1 and the inner glass tube 4. This design ensures the stability of the electrode in strongly alkaline, high-salt, and high-concentration solutions while providing a stable reference potential. A silicone rubber support 3 is fixedly connected inside the electrode housing structure 1 to support and fix the inner glass tube 4, maintaining the overall stability of the electrode structure. The elastic properties of the silicone rubber support 3 effectively buffer external impacts, preventing damage to the electrode in high-speed flowing water samples containing particulate matter.

The large-diameter flat membrane 5 is made of HA membrane material and is fabricated into a large-diameter planar membrane structure using a thick-film process; its bulb diameter is 8 mm. This design not only meets the measurement requirements for the electrode structure but also effectively reduces membrane impedance, improves electrode sensitivity, and reduces electrode response time.

[0023] In addition, the large-diameter flat membrane 5 is about 5 mm lower than the electrode housing structure 1. This structural design can protect the flat membrane from damage when measuring water samples with high flow rates and containing particulate matter, thus extending the service life of the electrode.

[0024] An open-type liquid network section 6 is located at the lower end of the electrode housing structure 1 and is sealed to the electrode housing structure 1 via O-rings and epoxy resin. The open-type liquid network section 6 effectively prevents clogging, ensuring stable measurement performance of the electrode during long-term use. An internal reference solution 7 fills the interior of the inner glass tube 4 of the electrode and is connected to the Ag / AgCl reference system 8, forming the electrode's reference system 9. The reference system 9 includes, but is not limited to, silver / silver chloride, silver ion traps, long lifetime, and long diffusion paths, ensuring the stability and accuracy of the electrode during long-term use.

[0025] In practice, the electrode shell structure 1 is made of corrosion-resistant material, which can adapt to the environment of highly alkaline, high-salt, and high-concentration water samples. The inner glass tube 4 of the electrode is fixed inside the electrode shell structure 1 by a silicone rubber support 3 to ensure the overall stability of the electrode structure.

[0026] A large-diameter flat membrane 5, fabricated using a thick-film process, is connected to the lower end of the inner glass tube 4 of the electrode. Its bulb diameter is 8 mm, and it is approximately 5 mm lower than the electrode shell structure 1 to protect the flat membrane from damage in high-speed flowing water samples containing particulate matter. An open liquid network section 6 is sealed to the electrode shell structure 1 using O-rings and epoxy resin, effectively preventing clogging during measurement. An inner reference solution 7 fills the interior of the inner glass tube 4 and is connected to the Ag / AgCl reference system 8, forming the electrode's reference system 9, ensuring measurement accuracy in strongly alkaline, high-salt, and high-concentration solutions.

[0027] This invention provides a shock- and wear-resistant large-diameter flat membrane industrial pH electrode structure. By optimizing the design of the electrode shell structure, silicone rubber support, large-diameter flat membrane, open liquid network section, and reference system, the electrode's durability and measurement performance in high-speed flowing water samples containing particulate matter are significantly improved. This electrode structure is particularly suitable for pH measurement in industrial processes, especially for long-term stable use in strongly alkaline, high-salt, and high-concentration solutions.
