Description

Technical Field

[0001] This utility model relates to the field of pH value detection and sampling technology, and in particular to a device for detecting and sampling the pH value of chemical liquids. Background Technology

[0002] Chemical wastewater refers to process wastewater, cooling water, exhaust gas scrubbing water, and equipment and site washing water discharged during chemical production. If this wastewater is discharged without treatment, it will cause pollution of water bodies in different ways and to varying degrees, thereby endangering human health and affecting industrial and agricultural production. Chemical wastewater requires the use of instruments to measure its pH level during treatment.

[0003] Existing chemical liquid pH testing and sampling devices can be referenced from Chinese Utility Model Patent Publication No. CN221667614U, which provides a chemical wastewater pH measuring device, including a base plate, an installation plate fixedly connected to the top of the base plate and located on the right side of the pH meter body, a damping bearing fixedly connected to the top of the installation plate, a vertical plate fixedly connected to the top of the inner ring of the damping bearing, a horizontal plate fixedly connected to the top of the vertical plate, an electric push rod fixedly connected to the top of the horizontal plate, a movable plate located below the horizontal plate, a detection probe fixedly connected to the bottom of the movable plate, a connecting wire fixedly connected to the top of the front end of the detection probe, a contact sensor fixedly connected to the front end of the top of the movable plate, a cleaning mechanism located on the top of the base plate and located behind the installation plate, and an automatic switching mechanism located on the top of the base plate and located on the right side of the installation plate. This utility model, through the coordinated use of the electric push rod, movable plate, contact sensor, detection probe, and automatic switching mechanism, can automatically test multiple wastewater test tubes, eliminating the need for repeated manual operation, reducing the workload of staff, and improving the testing efficiency.

[0004] However, in actual use, it was found that the device required manual rotation of the upright plate to the top of the cleaning frame for cleaning, which was cumbersome and inefficient. Furthermore, the water in the cleaning frame was reused, leading to deviations in the test results. Therefore, this application provides a chemical liquid pH value detection and sampling device to meet the needs. Utility Model Content

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] 1. In the above scheme, the detection probe that needs to be cleaned after testing only needs to be driven by the rotation of the motor to rotate the lead screw, which moves the second slider and moves the mounting bracket above the cleaning cup. The rotation of the second motor drives the screw to rotate, which moves the first slider and moves the protective shell downward, so that the detection probe enters the inner cavity of the cleaning cup. There is no need to rotate it manually.

[0016] 2. In the above scheme, the end of the water injection pipe away from the water injection pump is installed at the top of the water outlet ring, and the end of the water suction pipe away from the water pump passes through the water outlet ring and is set at the bottom of the cleaning cup. Clean cleaning water is injected into the water outlet ring by the water injection pump, and the inner wall of the cleaning cup is cleaned by several nozzles set at the bottom of the water outlet ring. The wastewater generated after cleaning is pumped out by the water suction pump and discharged into the water outlet ring. Clean cleaning water is injected again, which can ensure that the detection probe will not be interfered with by residual liquid during detection, thereby improving the accuracy of detection.

[0028] like Figure 1 and Figure 5 As shown, the outer casing 15 includes a second motor 151. A slide groove 152 is provided on the side wall of the outer casing 15. The output shaft of the second motor 151 is fixedly connected to a screw 153. A first slider 154 is threadedly connected to the outer edge of the screw 153. A connecting block 155 is fixedly connected to the first slider 154. The first slider 154 drives the connecting block 155 to move up and down. The connecting block 155 is slidably connected to the slide groove 152.

[0029] like Figure 1 and Figure 4As shown, the protective shell 16 includes a motor 161. A moving groove 162 is provided on the side wall of the protective shell 16. The output shaft of the motor 161 is fixedly connected to a lead screw 163. A second slider 164 is threadedly connected to the outer edge of the lead screw 163. A mounting bracket 165 is fixedly installed on the second slider 164. A stirring rod 166 is installed on the mounting bracket 165. A detection probe 168 is installed on the mounting bracket 165 and on one side of the stirring rod 166.

[0030] like Figure 1 and Figure 2 As shown, the end of the water injection pipe 12 away from the water injection pump 11 is installed at the top of the water outlet ring 9, and the end of the water extraction pipe 14 away from the water extraction pump 13 passes through the water outlet ring 9 and is set at the bottom of the cleaning cup 8. Clean cleaning water is injected into the water outlet ring 9 by the water injection pump 11, and the wastewater generated after cleaning is extracted by the water extraction pump 13 and discharged into the water outlet ring 9.
