Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a combined acid and alkali treatment device for industrial wastewater. Background Technology

[0002] In the process of industrial wastewater treatment, acid-base neutralization is one of the key process steps. As an important indicator reflecting the acidity or alkalinity of wastewater, accurate measurement of pH value is crucial for controlling the dosage of chemicals and ensuring the treatment effect. At present, pH value sensors are generally used for real-time monitoring in industrial wastewater acid-base combined treatment devices.

[0003] However, the following technical problems exist in actual operation: pH sensors are immersed in complex industrial wastewater for a long time, and their surfaces are easily covered with various organic and inorganic salts and other dirt. This dirt forms an isolation layer, which hinders the effective contact between the sensor electrodes and the wastewater, resulting in deviations in the measured values ​​and seriously affecting the detection accuracy. Traditional devices mostly use fixed-installation pH sensors, which require shutdown and manual disassembly for cleaning. This is not only cumbersome to operate, but also affects the continuous operation of the treatment system. Although some devices have a simple rinsing function, it is difficult to completely remove stubborn dirt, and the cleaning effect is limited. Therefore, we provide an industrial wastewater acid-base combined treatment device to solve the above problems. Utility Model Content

The ultrasonic cleaning device 13 in the vibration tank 404 removes the dirt on the surface of the pH sensor 303. The neutral water in the detection tank 405 is used to test the detection accuracy of the pH sensor 303. Specific Implementation Example 2

[0025] Please see Figure 1-5Based on specific embodiment 1, a first mounting plate 5 is bolted to one side of the wastewater acid and alkali treatment tank 1. A first hydraulic cylinder 6 is fixedly connected to the top of the first mounting plate 5. The output end of the first hydraulic cylinder 6 is fixedly connected to the top of the corrosion-resistant mounting rod 301. The first hydraulic cylinder 6 is installed by the first mounting plate 5 and is used to drive the pH sensor 303 to move up and down. An installation slot is opened inside the mounting block 302. The pH sensor 303 is located inside the installation slot and is bolted to the inside of the mounting block 302. The pH sensor 303 is installed and fixed. A second mounting plate 7 is bolted to one side of the wastewater acid and alkali treatment tank 1. A second hydraulic cylinder 8 is fixedly connected to one side of the second mounting plate 7. The output end of the second hydraulic cylinder 8 extends into the protective box 401 and is fixedly connected to the cleaning box 402. The hydraulic cylinder is existing technology and will not be described in detail here. Those skilled in the art can clearly understand its working principle. The second hydraulic cylinder 8 is installed through the second mounting plate 7. The second hydraulic cylinder 8 drives the cleaning box 402 to move. The first hydraulic cylinder 6 and the second hydraulic cylinder 8 are linked through an external controller to ensure the pH sensor 303 operates smoothly. 03 The internal lifting mechanism separates from the moving sequence of the cleaning tank 402. One side of the protective tank 401 is open. A water supply pipe 9 is fixedly connected inside the protective tank 401, and a water supply nozzle 10 is connected to the bottom of the water supply pipe 9. The water supply pipe 9 and the water supply nozzle 10 are used to replenish neutral water to the vibration tank 404 and the detection tank 405. The neutral water is supplied by an external purification system, and a water quality detection module is set up to ensure purity. A rinsing pipe 11 is fixedly connected inside the rinsing channel 403, and a rinsing nozzle 12 is connected to the surface of the rinsing pipe 11. The rinsing pipe 11 is connected to an external water source through a pipe. The rinsing pipe 11 and the rinsing nozzle 12 are used to monitor the pH sensor 3. 03. Rinsing is performed. An ultrasonic cleaning device 13 is placed inside the vibration tank 404. The ultrasonic cleaning device 13 is existing technology and will not be described in detail in this solution. Moreover, those skilled in the art can clearly understand its working principle. The bottom of the cleaning tank 402 is connected to a drain pipe 14, and the surface of the drain pipe 14 is connected to a self-control valve 15. The self-control valve 15 is existing technology and will not be described in detail in this solution. Moreover, those skilled in the art can clearly understand its working principle. The ultrasonic cleaning device 13 is used to clean dirt and other contaminants adhering to the surface of the pH sensor 303. The drain pipe 14 and the self-control valve 15 are used to discharge cleaning water and testing water.

[0026] The working principle of this utility model is as follows: the external controller periodically starts the first hydraulic cylinder 6, the first hydraulic cylinder 6 drives the pH value sensor 303 to move upward out of the wastewater acid and alkali treatment tank 1, at this time the external neutral water flows into the water supply pipe 9, and flows into the vibration tank 404 and the detection tank 405 through the water supply nozzle 10 at the bottom of the water supply pipe 9. Then the second hydraulic cylinder 8 drives the cleaning tank 402 to move out of the interior of the protective box 401.

[0027] The pH sensor 303 is positioned in the rinsing channel 403. External neutral water flows into the rinsing pipe 11 through the pipe and is sprayed onto the pH sensor 303 through the rinsing nozzle 12 to rinse the acidic and alkaline wastewater on the pH sensor 303. Then, the first hydraulic cylinder 6 continues to retract, causing the pH sensor 303 to continue to move upward. The second hydraulic cylinder 8 causes the cleaning tank 402 to continue to extend, so that the vibration tank 404 is located at the bottom of the pH sensor 303. The pH sensor 303 is then moved down into the vibrating tank 404. The ultrasonic cleaning device 13 is used to ultrasonically vibrate and clean the dirt attached to the surface of the pH sensor 303. After cleaning, the above steps can be repeated to move it back to the rinsing channel 403 for rinsing.

[0028] After rinsing, move the pH sensor 303 to the detection tank 405 and use the pH sensor 303 to detect the pH value of the neutral water in the detection tank 405. Determine whether the detection accuracy of the pH sensor 303 is correct by checking whether the detected value is deviated. If the deviation is large, the pH sensor 303 needs to be disassembled and replaced. If the detection result is accurate, the pH sensor 303 is reset back to the wastewater acid and alkali treatment tank 1 for continued use.
