Technical Field
[0001] This invention belongs to the technical field of conductivity meter equipment, specifically relating to a calibration auxiliary device for acidity conductivity meters based on triaxial adjustment. Background Technology
[0002] Conductivity analyzers can be used for continuous monitoring of conductivity values in solutions from thermal power plants, chemical fertilizer plants, metallurgical plants, and tap water. During use, conductivity analyzers may be affected by environmental factors, quality issues, or drift caused by prolonged use, which may reduce the accuracy of their test results. Therefore, to ensure the accuracy of the conductivity analyzer's test results, it is necessary to calibrate it regularly.
[0003] In the current calibration process of acidity conductivity meters, to ensure the accuracy of the calibration results, at least three beakers need to be prepared, and the above calibration operation needs to be repeated at least three times. This operation is quite cumbersome, and the standard solution in the beakers is always exposed to the air during the calibration process. This makes the standard solution susceptible to the influence of dust, suspended matter, and other contaminants in the air, resulting in large fluctuations in the conductivity value during the detection process. This leads to a long calibration time for the conductivity analyzer and a decrease in the accuracy of the calibration results. At the same time, during the calibration process, manual switching of the work station and the standard solution is prone to errors, and it is difficult to ensure the precision of the contact between the sensor and the standard solution, resulting in low calibration accuracy. In addition, the calibration process is time-consuming, which seriously affects the calibration efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a calibration auxiliary device for acidity conductivity meters based on triaxial adjustment, which can automate the calibration process of acidity conductivity meters, reduce errors and labor intensity caused by manual operation, and improve calibration accuracy and efficiency.
[0005] The specific technical solution adopted by this utility model is as follows: A calibration auxiliary device for an acidity conductivity meter based on triaxial adjustment includes a device frame, inside which a multi-axis driver is fixed, and one side of the device frame is fixedly connected to an electrical control cabinet, which is electrically connected to the multi-axis driver. The auxiliary mechanism includes multiple processing stations, a water bath, an ultrasonic cleaner, and a standard device. The multiple processing stations are fixed inside the equipment frame and are respectively connected to the water bath and the ultrasonic cleaner. The standard device is fixedly connected to the output end of the multi-axis driver, and the input end of the standard device is detachably connected to the conductivity meter and the pH meter amplifier. The multi-axis driver drives the conductivity meter and pH meter amplifier through multiple processing stations in sequence. The water bath works in conjunction with these processing stations to set and control the heating temperature of the standard solution, ensuring that the standard solution is at the temperature required for calibration. The ultrasonic cleaner works in conjunction with these processing stations to clean the conductivity meter and pH meter amplifier. The standard device is connected to the conductivity meter and pH meter amplifier to effectively read the standard values, thus improving calibration efficiency.
[0006] Furthermore, the output end of the multi-axis driver is fixedly connected to one side of the fixed plate, and the other side of the fixed plate is slidably connected to multiple clamping plates. The multiple clamping plates are all fixed to the output end of the electric clamp, and the sides of the multiple clamping plates that are close to each other are slidably connected to the standard.
[0007] Furthermore, the plurality of processing stations include a water washing station, an air shower station, an ultrasonic station, and a plurality of water bath stations. The ultrasonic cleaning machine is electrically connected to the ultrasonic station, and the interior of the water bath contains a plurality of the water bath stations.
[0008] Furthermore, a washing pipe is fixed inside the washing station, and multiple washing holes are opened on the washing pipe. One side of the washing station is connected to a clean water tank, and a wastewater tank is fixed at the bottom of the washing station.
[0009] Furthermore, the air shower station is internally wrapped with air ducts, which have multiple air shower holes, and the bottom of the air shower station is connected to the sewage tank.
[0010] Furthermore, the interiors of the multiple water bath stations are respectively filled with standard solutions for pH meter amplifiers and standard solutions for conductivity meters.
[0011] The technical effects achieved by this utility model are as follows: This utility model discloses a triaxially adjustable acidity conductivity meter calibration auxiliary device. A multi-axis driver sequentially moves the conductivity meter and pH meter amplifier through multiple processing stations, improving calibration efficiency and significantly shortening operation time. A water bath, working in conjunction with the processing stations, sets and heats the standard solution, ensuring it is at the required calibration temperature, guaranteeing the standardization and consistency of the calibration operation, and improving the reliability of the calibration results. An ultrasonic cleaner, also working in conjunction with the processing stations, cleans the conductivity meter and pH meter amplifier, allowing for effective reading of standard values through a standard analyzer. This further enhances calibration efficiency and detection accuracy, while also expanding the device's applicability to accommodate varying quantities of standard solutions.

It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0015] like Figures 1 to 4 As shown, the acidity conductivity meter calibration auxiliary device based on triaxial adjustment includes a device frame 10, a multi-axis driver 11 is fixed inside the device frame 10, and one side of the device frame 10 is fixedly connected to the electrical control cabinet 12. The electrical control cabinet 12 is electrically connected to the multi-axis driver 11. The auxiliary mechanism 20 includes multiple processing stations 21, a water bath 22, an ultrasonic cleaner 23, and a standard device 24. The multiple processing stations 21 are all fixed inside the equipment frame 10, and the multiple processing stations 21 are respectively matched with the water bath 22 and the ultrasonic cleaner 23. The standard device 24 is fixedly connected to the output end of the multi-axis driver 11, and the input end of the standard device 24 is detachably connected to the conductivity meter and the pH meter amplifier. The system uses a multi-axis driver 11 to drive the conductivity meter and pH meter amplifier through multiple processing stations 21. A water bath 22 works in conjunction with the multiple processing stations 21 to set and control the heating temperature of the standard solution, ensuring that the standard solution is at the temperature required for calibration. An ultrasonic cleaner 23 works in conjunction with the multiple processing stations 21 to clean the conductivity meter and pH meter amplifier. A standard device 24 is connected to the conductivity meter and pH meter amplifier to effectively read the standard values, thus effectively improving calibration efficiency.
[0016] In this embodiment, it should be noted that the multi-axis drive 11 includes X-axis, Y-axis, and Z-axis drives, ensuring omnidirectional adjustment within the space inside the equipment rack 10, thereby effectively driving the conductivity meter and pH meter amplifier for cleaning; simultaneously, the electrical control cabinet 12 is equipped with electrical components to provide power support for various parts of the equipment; and the electrical control cabinet 12 is equipped with an aviation plug and a power cord of sufficient length to connect to the production line power supply, with a power of ≥5KW and a voltage of AC220V, meeting the power requirements of the equipment; the electrical control cabinet 12 is also equipped with an interface for connecting to the production line compressed air or air compressor compressed air interface, providing an air source for the air shower station 212; and The standard unit 24 has an integrated program that can analyze and output the standard values of the pH meter amplifier according to the process settings. It can also analyze and output the standard values of the conductivity meter. At the same time, it can automatically generate test reports according to the calibration process for personnel to record and observe. This is a conventional technical method and will not be described in detail here. Specifically, the multi-axis driver 11 drives the conductivity meter or pH meter amplifier to move precisely, ensuring that the sensor accurately reaches each station. After passing through the cleaning and drying at each station and the cleaning with standard solution, the conductivity meter and pH meter amplifier are effectively calibrated to ensure that they remain accurate for subsequent measurements.
[0017] like Figure 2 , Figure 4 As shown, the Z-axis driver of the multi-axis driver 11 is fixedly connected to one side of the fixed plate 13, and the other side of the fixed plate 13 is slidably connected to multiple clamping plates 131. The multiple clamping plates 131 are all fixed to the output end of the electric clamp, and the sides of the multiple clamping plates 131 that are close to each other are slidably connected to the standard 24. It should be noted that there are two clamping plates 131, which are symmetrically distributed along the vertical center line of the fixed plate 13. The inner side of the clamping plate 131 is provided with an arc-shaped groove, and the arc-shaped groove is provided with anti-slip texture to enhance the stability of clamping. The conductivity meter and pH meter amplifier are placed between the clamping plates 131. By controlling the electric clamp, the clamping plates 131 on both sides are moved closer to each other synchronously, thereby effectively fixing the conductivity meter and pH meter amplifier and ensuring stability during movement.
[0018] like Figure 3 , Figure 4As shown, the multiple processing stations 21 include a water washing station 211, an air shower station 212, an ultrasonic station 213, and multiple water bath stations 214. The ultrasonic cleaner 23 is electrically connected to the ultrasonic station 213. The water bath 22 contains multiple water bath stations 214 connected to each other. It should be noted that the water bath stations 214 include three stations for placing pH meter standard solutions, two stations for placing conductivity standard solutions, and one sensor station for measuring the temperature of the water bath 22. The temperature is accurately monitored through the sensor station to ensure that the calibration solution is accurately at the temperature required for calibration.
[0019] like Figure 2 , Figure 3 As shown, a washing station 211 has a washing pipe wound around it inside. The washing pipe has multiple washing holes. One side of the washing station 211 is connected to a clean water tank, and a wastewater tank 25 is fixed at the bottom of the washing station 211. During calibration, the conductivity meter and pH meter amplifier are driven into the washing station 211 by the multi-axis driver 11. The water in the clean water tank is used to rinse the sensor by controlling the washing pipe. At the same time, the wastewater tank 25 at the bottom can effectively collect the washing liquid.
[0020] Preferably, the air shower station 212 has an internal air duct wound around it, with multiple air shower holes on the air duct, and the bottom of the air shower station 212 is connected to the sewage tank 25. After the water washing is completed, the multi-axis driver 11 drives the sensor to move to the air shower station 212 and connects it to the air duct through the air pipe set inside the electrical control cabinet 12, thereby generating gas. The sensor can be dried and cleaned in all directions through the multiple air shower holes.
[0021] Preferably, the interior of the multiple water bath stations 214 contains standard solutions for pH meter amplifiers and standard solutions for conductivity meters. There are three types of standard solutions for pH meter amplifiers and two types of standard solutions for conductivity meters. During calibration, the sensor needs to be passed through each standard solution in sequence for effective calibration.
[0022] In this embodiment, it should be noted that during the pH meter amplifier calibration process, the multi-axis driver 11 drives the pH meter amplifier sensor to sequentially pass through the water washing station 211 for cleaning. The sensor is then moved to the air shower station 212 for air drying, and then to the ultrasonic station 213 for ultrasonic cleaning, ensuring effective removal of any adhering substances and liquids from the sensor. The sensor is then passed through the water washing station 211 and the air shower station 212 again, and then placed in the first pH sensor standard solution for calibration measurement. After the measurement is completed, the pH sensor is cleaned and dried again for measurement with the second and third standard solutions. At each measurement station, the sensor performs corresponding operations according to a preset time to ensure the cleaning and calibration effect. Specifically, the conductivity meter electrode calibration process is similar to the pH meter sensor steps described above, with the operation time of each station executed according to a preset program.
[0023] The working principle of this utility model is as follows: When a conductivity meter or pH meter amplifier needs to be calibrated, the conductivity meter or pH meter amplifier is placed in the clamping plate 131 and fixed thereon. Then, the standard device 24 is connected to the conductivity meter and pH meter amplifier to be tested. The multi-axis driver 11 drives the conductivity meter or pH meter amplifier through the water washing station 211, the air shower station 212, and the ultrasonic station 213 for cleaning. Subsequently, when the conductivity meter and pH meter amplifier come into contact with multiple conductivity standard solutions and multiple pH meter amplifier standard solutions in sequence, the standard device 24 can read the standard values of the conductivity meter and pH meter amplifier in real time and automatically generate a test report according to the calibration process, ensuring that the calibration efficiency is effectively improved.
[0024] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
