Description

Technical Field

[0001] This utility model relates to the field of pH electrode protection technology, specifically a pH / ORP electrode protection device. Background Technology

[0002] Brine purification involves dissolving raw salt in water to create crude saturated brine. Sodium carbonate, sodium hydroxide, and barium chloride are then added to the brine, reacting with calcium, magnesium, and sulfate ions to form precipitates. These precipitates and mechanical impurities naturally settle and separate due to gravity. Suspended solids in the saturated brine are removed through a sand filter, and the solution is then neutralized with hydrochloric acid to reach the specified pH value, thus obtaining qualified refined brine for electrolysis.

[0003] To ensure the stable operation of the brine refining process and achieve real-time monitoring of the pH and ORP values ​​of the primary brine, the traditional approach is to set up multiple pH and ORP monitoring points in the primary brine process unit and install pH and ORP electrodes between the pipelines to achieve online monitoring of the fluid medium.

[0004] However, the electrode is subjected to long-term scouring and corrosion by salt water, and cannot filter impurities in the liquid, which severely reduces its service life. To address these issues, a pH / ORP electrode protection device is proposed. Utility Model Content

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0030] Reference Figure 1 , Figure 2 and Figure 3This utility model discloses a pH / ORP electrode protection device, comprising a working cylinder 1 for mounting electrodes. The working cylinder 1 has through holes 3 at its bottom and left side for easy installation of inlet / outlet cylinders 2. Buffer components are installed within both through holes 3. A connecting ring 8 is connected to the bottom of the lower buffer component, facilitating the installation of a filter plate 14. Removal blocks 10 are fixedly connected to both sides of the connecting ring 8. Slots 11 are provided at the bottom of both removal blocks 10 for limiting the movement of a flexible spring sheet 16. The outer side of the removal blocks 10 has... There is a slot 12, which communicates with the slot 11. A filter plate 14 is provided at the bottom of the connecting ring 8 to prevent impurities from entering and affecting the normal operation of the electrode or damaging the electrode. Connecting plates 15 are fixedly connected to both sides of the filter plate 14. Flexible spring pieces 16 are fixedly connected to the top of the two connecting plates 15. The U-shaped flexible spring pieces 16 can be connected through the connecting plates 15. A pressing block 17 is fixedly connected to the outside of the flexible spring piece 16. A threaded tube 19 is fixedly connected to the top of the working cylinder 1. The electrode head is installed by means of the threaded tube 19 and the threaded connection of the electrode head.

[0031] Reference Figure 2 The buffer assembly includes an inlet / outlet cylinder 2, with a funnel tube 20 fixedly connected inside. A support rod 4 is fixedly connected to the larger opening end of the funnel tube 20. A guide rod 5 is fixedly connected to the middle of the support rod 4. A buffer plate 7 is slidably connected through the outer ring of the guide rod 5. A spring 6 is sleeved on the outer ring of the guide rod 5. One end of the spring 6 is fixedly connected to the support rod 4, and the other end is fixedly connected to the buffer plate 7. Both inlet / outlet cylinders 2 are fixedly connected to a connecting flange 18, which is located outside the working cylinder 1. Both inlet / outlet cylinders 2 are fixedly connected to a through hole 3. The bottom of the lower inlet / outlet cylinder 2 is fixedly connected to a connecting ring 8. A limit ring 9 is fixedly connected to the bottom of the guide rod 5, and the limit ring 9 is located outside the buffer plate 7. The buffer assembly allows brine to enter the working cylinder 1 from a lower position and then exit from a higher position, thus achieving a buffering effect when brine flows into the working cylinder 1, ensuring measurement stability, and avoiding excessive scouring of the electrode probe.

[0032] Reference Figure 3 Two limiting blocks 13 are fixedly connected inside the slot 11. The limiting blocks 13 are located on both sides of the slot 12 and can limit the outer end of the flexible spring sheet 16. The pressing block 17 is located inside the slot 12 and the flexible spring sheet 16 is located inside the slot 11. The flexible spring sheet 16 can be inserted into the slot 11 to facilitate the installation of the filter plate 14.

[0033] Working Principle: During use, the pipeline can be connected via the connecting flange 18 on the outside of the inlet / outlet cylinder 2. The operator can install the electrode head using the threaded connection 19, allowing it to be smoothly inserted into the working cylinder 1. A buffer assembly provides cushioning protection as the solution enters and exits the working cylinder 1. For the inlet / outlet cylinder 2 in the buffer assembly, when the solution flows in from the outside or out from the inlet / outlet cylinder 2, the solution first passes through the funnel tube 20. Taking inflow as an example, the solution flows inward along the funnel tube 20, impacting the buffer plate 7. Since the buffer plate 7 is fitted onto the guide rod 5, and the guide rod 5 is fitted with a spring 6, under the impact of the solution, the buffer plate 7 slides upward along the guide rod 5, simultaneously compressing the spring 6. The spring 6 acts as a buffer, absorbing the impact force from the solution flow and preventing direct damage to internal components such as the electrode. When the impact force decreases, the spring 6 rebounds, pushing the buffer plate 7 back to its initial position, awaiting the next buffering action. The limiting ring 9 at the bottom of the guide rod 5 prevents the buffer sheet 7 from slipping off the guide rod 5, ensuring the stability of the buffer assembly structure. The filter plate 14 is used to filter the solution entering and exiting the working cylinder 1, preventing impurities from entering and affecting the normal operation of the electrode or damaging the electrode. During installation, the flexible spring sheets 16 on both sides of the filter plate 14 are inserted into the slots 11 in the disassembly block 10. At this time, the U-shaped flexible spring sheets 16 are compressed by the limiting block 13 and contract. The pressing block 17 enters the slot 12. When the flexible spring sheets 16 are fully inserted into the slot 11, the outer end of the flexible spring sheets 16 is disengaged from the compression of the limiting block 13, thereby resetting and opening up in the slot 11. The limiting block 13 limits the flexible spring sheets 16, completing the installation of the filter plate 14.
