Description

Technical Field

[0001] The invention relates to the technical field of liquid level monitoring, and in particular to a real-time liquid level monitoring device for a well site mud pool. Background Art

[0002] Mud pool is a commonly used solid-liquid separation treatment equipment, widely used in chemical industry, metallurgy, environmental protection and other fields, especially in wastewater treatment, the application of mud pool is very common. Mud pool separates solid particles from wastewater through gravity separation, reduces the concentration of solid particles and pollutant content in water, so as to achieve the purpose of purifying water quality;

[0003] At present, most of the data on the mud level in drilling projects are collected through ultrasonic sensors. Due to the action of the mud mixer, the mud level in the mud pool has relatively large fluctuations, the liquid level is uneven, and a slope is generated, resulting in the ultrasonic probe often not receiving the signal or the signal fluctuating greatly. In addition, a large number of bubbles are often generated due to the action of mud additives, resulting in inaccurate measurement data using existing measurement methods. In severe cases, it is even impossible to use ultrasonic sensors to obtain the reflected signal of the liquid level. In this case, manual measurement has to be adopted. However, manual measurement is not only high in intensity but also low in efficiency, and it is impossible to perform subsequent monitoring and early warning operations. At the same time, the monitoring device in the existing technology is difficult to make corresponding adjustments according to the mud pools in different environments, sizes, and heights, resulting in certain errors in the monitoring process, affecting its monitoring effect.
