Embodiment Construction

[0015] The structure of the present invention will be described in detail in conjunction with the accompanying drawings.

[0016] A load-bearing structure for measuring fluid concentration by online ultrasonic method, characterized in that: the main body 1 adopts gradual and smooth curve shape design, conforms to the fluid mechanics model structure, effectively reduces the frictional resistance between the fluid and the solid wall, so as to obtain The most stable measurement sample data ensures the representative data of the measurement sample, and also reduces the mechanism wear caused by obstruction. This structure also reduces the probability of turbulent flow, and weakens the influence of air bubbles on the sound wave attenuation and diffusion of the transducer when turbulent flow occurs; the precision casting structure reduces the roughness of the tube wall, and the inner wall is smooth and clean, reducing abrasion. At the streamline shape of the main body 1, a sending tr...

Abstract

A bearing structure for online ultrasonic method measurement of the concentration of a fluid adopts a streamline main body (1) molding design, reduces the occurrence possibility of turbulent flow, and decreases the influences of bubbles on the attenuation diffusion of energy transducer signals due to the turbulent flow. Gradually varied smooth curve design accords with a hydrodynamic model structure, effectively reduces the friction resistance between the fluid and a solid wall surface to obtain most stable measured sample data in order to ensure the representative data of the above measured sample, and reduces the mechanism wearing generated due to obstruction. The streamline main body is provided with a transmitting energy transducer and a receiving energy transducer, and anti-wear rubber layers are arranged among the two energy transducers and a medium, so the wearing of the energy transducers is avoided, and no pollution is guaranteed, thereby the structure is high life composition mode with no wearing, no pollution and no contact. The bearing structure has the advantages of online property, real time guidance of production, efficiency increase and energy consumption reduction.

Description

technical field [0001] The invention relates to a fluid structure, in particular to a bearing structure for measuring fluid concentration by an online ultrasonic method. Background technique [0002] Fluid concentration is one of the important parameters for detection and control in the industrial field production process. In the cycle of each operation, the fluid concentration has a special meaning. There is a problem of lag in the concentration value obtained by off-line measurement and sampling tank measurement, and the real-time performance of equipment control and adjustment is poor. At present, the bearing structures of ultrasonic transducers for online measurement of fluid concentration all adopt ordinary circular tube structures, which do not have a good way to deal with the influence of bubbles in the fluid on ultrasonic signals, causing great errors in the measurement results; and the transducer The transducers are in direct contact with the fluid, which will inev...
