Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a pH measuring device with automatic maintenance function. Background Technology

[0002] In the raw water hardening treatment process, a mixture of reclaimed water and lime slurry is used to remove hardness components from the water. To precisely control the amount of lime slurry added and ensure effective hardening, long-term, stable monitoring of the pH value of the mixture is necessary. However, because the mixture contains particulate matter such as lime slurry, these particles crystallize on the pH meter probe surface after prolonged contact, forming a thick layer of white, flocculent solid. This crystallization phenomenon not only severely affects the accuracy of pH meter measurements, making the monitoring data unreliable, but also causes severe corrosion and wear to the pH meter probe, significantly shortening its lifespan. To maintain the probe's measurement accuracy and extend its lifespan, regular cleaning and maintenance are usually required. However, traditional maintenance methods mostly rely on manual operation, which is not only inefficient but also makes it difficult to guarantee the timeliness and effectiveness of each maintenance. Furthermore, manual maintenance is even more challenging for large bodies of water or inaccessible measurement points. Utility Model Content

[0005] A pH measuring device with automatic maintenance function includes a bracket, a cylinder, a cylinder piston rod, a pH meter probe, a water outlet pipe, a nozzle, a valve, and a sensing device. The bracket includes a horizontal beam parallel to the ground and a vertical beam perpendicular to the ground, forming an inverted L-shaped bracket. The cylinder is mounted on the horizontal beam, and the cylinder piston rod passes through the horizontal beam, with the pH meter probe located at the bottom of the cylinder piston rod.

The sensing device includes a sensing block and a sensing probe. The sensing block is located at the end of the cylinder piston rod, and the sensing probe is located on the water outlet pipe. A valve is also provided on the water outlet pipe, and the valve is connected to the sensing device.

[0006] Furthermore, the valve is a solenoid valve.

[0007] Furthermore, the sensing device also includes a signal processor.

[0012] This invention provides a pH measuring device with automatic maintenance function. By incorporating a cylinder and a sensing device, it achieves automatic measurement and cleaning of the pH meter probe, significantly reducing manual intervention by on-site personnel, lowering labor intensity, and improving work efficiency.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0017] Reference Appendix Figure 1A pH measuring device with automatic maintenance function includes a bracket 1, a cylinder 2, a cylinder piston rod 3, a pH meter probe 4, a water outlet pipe 5, a nozzle 6, a valve, and a sensing device. The bracket 1 includes a horizontal beam parallel to the ground and a vertical beam perpendicular to the ground, forming an inverted L-shaped bracket. The cylinder 2 is mounted on the horizontal beam, and the cylinder piston rod 3 passes through the horizontal beam. The pH meter probe is located at the bottom of the cylinder piston rod 3. The water outlet pipe 5 is mounted on the vertical beam and is positioned at the highest horizontal position of the pH meter probe 4. The nozzle 6 is located at the end of the water outlet pipe 5. The sensing device includes a sensing block 7 and a sensing probe 8. The sensing block 7 is located at the end of the cylinder piston rod 3, and the sensing probe 8 is located on the water outlet pipe 5.

[0021] In one embodiment of this utility model, the pH meter probe 4 is connected to the bottom of the cylinder piston rod 3 via a detachable connector, which facilitates the replacement of different models of pH meter probe 4 to meet different testing needs.

[0022] In one embodiment of this utility model, a flow regulator is provided on the water outlet pipe 5 to regulate the flow rate of the rinsing water, prevent the rinsing water flow rate from being too large and affecting the service life of the pH meter probe 4, and at the same time avoid a large amount of rinsing water entering the water tank and affecting the pH value of the liquid in the water tank.

[0023] In use, an external air source drives the cylinder piston rod 3 to move up and down, thereby moving the pH meter probe 4 into or out of the mixed solution in the water tank. After measuring the pH value of the solution, the pneumatic piston rod 3 moves upward. When the sensing block 7 at the end of the pneumatic piston rod 3 is at the same horizontal position as the sensing probe 8, the sensing probe 8 senses the sensing block 7 and sends the sensing signal to the signal processor. The signal processor then controls the solenoid valve to open, and the rinsing water rinses the pH meter probe 4 through the nozzle 6.
