Ultrasonic cleaning system for pH meter

Abstract

The invention relates to an ultrasonic cleaning system for a pH meter, and belongs to the field of ultrasonic cleaning. The ultrasonic cleaning system comprises a computer, an acquisition card, a pH meter measuring instrument, a hydrophone tank and an ultrasonic generator which are connected in sequence, wherein a pH detector is arranged on the top of the hydrophone tank and is connected with the pH meter measuring instrument through a transmission line for transmission; the hydrophone tank comprises an ultrasonic cleaning cylinder and an ultrasonic transducer; the ultrasonic cleaning cylinder is positioned at the bottom of the hydrophone tank and is connected with the ultrasonic generator through a transmission line for transmission; the ultrasonic transducer is positioned at the bottom of the ultrasonic cleaning cylinder and is fixed on the inner wall of the bottom of the ultrasonic cleaning cylinder; and the ultrasonic generator is connected with the pH meter measuring instrument for transmission. By the ultrasonic cleaning system, the measuring instrument can be cleaned automatically and efficiently, and the sensitivity and measuring accuracy of the measuring instrument can be guaranteed.

Description

technical field [0001] The invention relates to an ultrasonic cleaning system for a pH meter, belonging to the field of ultrasonic cleaning. Background technique [0002] At present, the commonly used method for surface water monitoring is to take fixed-point samples at certain sections of the river at regular intervals, and then bring them back to the laboratory for analysis. Because the water quality of surface water is often affected by factors such as the discharge of coastal pollution sources, meteorological conditions and seasonal changes, the water quality changes with time and space. In this way, it is impossible to fully understand the current situation of water quality pollution, timely reflect abnormal changes in water quality, and track pollution sources; it cannot provide a reliable basis for total monitoring. [0003] At the same time, because the sewage contains a large amount of toxic and harmful substances, suspended solids, sediment, rust, odor pollutants...

Problems solved by technology

[0003] At the same time, because the sewage contains a large amount of toxic and harmful substances, suspended solids, sediment, rust, odor pollutants, bacterial viruses and other substances, the dirt adheres to the measuring instrument during measurement, which will affect the testing instrument for a long time, and then It affects the detection value, reduces the sensitivity and measurement accuracy, or even fails, so we need to clean it regularly. In the past, we used regular manual cleaning to ensure the cleanliness of the detection instrument, but this cannot guarantee timely and effective Keeping the detection sensitivity of the instrument can not improve the cleaning speed and cleaning quality; and it increases the labor intensity, and further, it will cause harm to people who are directly exposed to harmful cleaning liquid; it also needs to interrupt the measurement like manual cleaning, which will affect the automatic detection
