On-line dirt prevention and removing device adopting ultrasonic wave focusing

Abstract

The invention provides an on-line dirt prevention and removing device adopting ultrasonic wave focusing. The on-line dirt prevention and removing device comprises a shell and an ultrasonic wave generator, and is characterized in that a liquid flowing channel is formed in the shell, a circulation cooling room, an amplification rod and a cold water conveying pipe are arranged in the shell, an ultrasonic transducer is arranged in the circulation cooling room, an on-line cleaning controller connected with the ultrasonic transducer is further connected to the ultrasonic wave generator, the amplification rod is of an inverted trapezoid-shaped structure, the top end of the amplification rod is a concaved surface and is distributed on the inner side of the shell in a semicircle focusing mode, the ultrasonic transducer is controlled by the on-line cleaning controller to convert an electric signal to mechanical energy of ultrasonic vibration, and then ultrasonic waves are emitted by the amplification rod to remove dirt. Due to the adoption of the structure, on-line cleaning control of internally arranged test electrodes or probes is achieved, effective cleaning in the on-line cleaning process can be achieved in an industrial automatic control mode, the problems of detaching, cleaning and calibrating of the internally arranged test electrodes or the probes are omitted, and complex product process requirements can be met.

Problems solved by technology

[0002] The evaporation and boiling process of the sugar industry is generally carried out in large tanks, and the concentration, temperature and other liquids in the tank are generally detected by electrodes or probes. In the process of industrial online detection and analysis, the test electrodes are easily affected by the Due to the influence of suspended particles, chemical reagents, colloids, minerals or other sediments, the electrode will be polluted and scaled, which will reduce the sensitivity and measurement accuracy of the test electrode, or even fail completely. Therefore, the test electrode needs to be cleaned regularly. According to the installation conditions of the electrodes, the external electrodes are generally pulled out and replaced with spare electrodes for manual cleaning. The more commonly used cleaning methods include mechanical brushing, jet cleaning, ultrasonic cleaning and other manual and automatic cleaning measures, but for built-in electrodes or test probes This method is not suitable, the calibration and cleaning effect of the electrode will greatly affect the test results

[0003] In my country's sugar industry, two kinds of sulfurous acid method and carbonic acid method are commonly used to clarify sugarcane juice. Since the sugarcane juice of these two treatment processes contains a large amount of scaling components such as calcium carbonate, calcium sulfite and magnesium salt, the sugarcane juice is The process of heating, evaporation and concentrated crystallization can easily form dense scale on the surface of the equipment and the test electrode. Sugar factories generally use wheel washing to remove these scales, but the surface of the built-in test electrode can be removed without disassembly. , the traditional high-pressure water washing, mechanical brush and other methods are difficult to touch the surface of the electrode. The existing ultrasonic cleaning devices on the market do not have cleaning equipment for built-in electrodes, and the commonly used ultrasonic frequency is generally 15-40KHZ. It is also not suitable for production in high temperature and high ash environment
