Embodiment 1

[0038] In order to compare the ultrasonic emission effect of the ultrasonic transducer of the present invention and the ordinary stainless steel plate transmitter head transducer, the connection method of the test device is as follows image 3 Shown. According to the industrial production conditions of a zinc industry group company, we designed a static pipeline ultrasonic field strength test system. The equipment includes: F40 digital synthesis function signal generator, power amplifier (HSA4011), ultrasonic transducer, 3770mm long polyethylene pipe, digital oscilloscope (TDS2024), and ultrasonic probe. The system is used to test and compare the ultrasonic emission intensity of the ultrasonic transducer of the present invention and the ordinary stainless steel plate transmitter head transducer. In order to facilitate the characterization, the size, transmission power, and operating frequency of the two ultrasonic transducers are the same.

Embodiment 2

[0047] In this embodiment, comparing the influence of the diameter of the thick end boss of the frustum-shaped probe on the transmission of ultrasonic intensity, the connection method of the test device is as follows: image 3 Shown. The diameter of the boss should not be too small: because the acoustic impedance Z of plastic (taking polyethylene as an example), aluminum, and ceramic is about 4.0078g / cm respectively 2 s, 81.7g / cm 2 s, 87.04g / cm 2 s, the acoustic impedance of polyethylene is quite different from that of aluminum and ceramics. The plastic support plate is placed between the truncated cone-shaped waveguide and the ceramic ultrasonic transmitter to form two acoustic reflection interfaces, which directly affects the transmission of ultrasonic waves . The diameter of the boss is small, and the ultrasonic intensity transmission effect is not good. The diameter of the boss should not be too large, otherwise the effective area of ​​the acid-proof gasket is small and the...

Embodiment 3

[0053] Prepare respectively 0.05mol / L, 0.1mol / L, 0.2mol / L, 0.5mol / L, 1.0mol / L H 2 SO 4 , HCl, HNO 3 Aqueous solution, replace the zinc sulfate aqueous solution in Example 1 with H of different acidity 2 SO 4 , HCl, HNO 3 Water solution, and then connect the ultrasonic descaler to the ultrasonic generator for a one-month test. The connection method of the test device is as follows image 3 Shown. One month later, the ultrasonic descaling device was disassembled, and the corrosion degree of the ceramic ultrasonic transmitter head of the ultrasonic transducer composite transmitter device was observed. The result showed that the ceramic ultrasonic transmitter head in the strong acid aqueous solution of 0.05mol / L has a smooth surface. Not corroded; the surface of the ceramic ultrasonic transmitter in the strong acid aqueous solution of 0.1mol / L is smooth and not corroded; the surface of the ceramic ultrasonic transmitter in the strong acid aqueous solution of 0.2mol / L is smooth and no...

Abstract

The invention relates to an ultrasonic transducer used in a strong-acid environment. The ultrasonic transducer mainly comprises a ceramic ultrasonic emission head, a frustum-shaped waveguide bar, an annular ceramic piezoelectric vibrator and a steel load, wherein the ultrasonic emission head is fixedly connected with the thick end of the waveguide bar by a thumb screw; a plastic support plate is connected with a boss in a sleeving manner; an acidproof washer is arranged between the plastic support plate and the emission head; and the thin end of the waveguide bar is sequentially connected with the annular ceramic piezoelectric vibrator and the steel load by a connecting threaded rod. The ultrasonic transducer can be used in the strong-acid environment, achieves scaling prevention and descaling during conveying of acid salt liquid in an organic high polymer pipeline, and improves the liquid conveying efficiency of the pipeline. The repair cycle interval of the pipeline is delayed greatly, the labor cost is lowered, the production efficiency is improved, materials used by the transducer are simple and easy to obtain, the repeatability is good, the mounting technical requirement is low, and the transducer is convenient to popularize, simple in structure, good in effect, low in manufacturing cost and suitable for a factory.

Description

Technical field [0001] The present invention relates to the technical field of ultrasonic transducers, in particular to an ultrasonic transducer used in a strong acid environment. Background technique [0002] Ultrasonic descaling is to use the physical characteristics of ultrasonic cavitation effect, shearing effect and inhibition effect in the propagation process, and achieve the effect of anti-scaling and descaling by changing the physical structure of water. Do you need to add any chemicals to the ultrasonic descaling? There is no harm to the human body; the descaling effect is obvious; the equipment is small in size, easy to install, and does not affect the normal use of the heat exchange equipment; the operation is simple and the degree of maintenance is high, and there is no special person to operate and manage , Non-corrosive equipment, long service life; online non-stop production, anti-scaling, two-way function of descaling, etc., ultrasonic descalers have been used in m...
