The adhesion of viscous materials such as soil to the surface of a working part is a common phenomenon in engineering. The problem of adhesion of loose viscous materials with different degrees exists in the fields of agriculture, engineering machinery, coal, municipal administration, metallurgy, cement and the like, the operation quality, the operation efficiency and the construction progress are influenced, the energy consumption is increased, the carbon emission is indirectly increased, and the double-carbon economy is not met.
In order to solve the problem, scholars at home and abroad carry out theoretical and experimental researches on the problem from different aspects and develop corresponding viscosity-reducing and resistance-reducing methods and technologies. At present, the vibration, scraping, inflation, sprinkling, coating of low surface energy materials and other forms are mainly adopted, and although certain results are achieved, practical application faces many limitations, such as environmental protection, convenience, durability and the like.
Theoretical studies have shown that the water film between the viscous material and the component surface plays a decisive role in the adhesion behavior, with the adhesion resistance decreasing with increasing water film. The electroosmosis technology has the characteristics that the hydrated cations in the soil are moved towards the negative electrode by the action of the electric field force, the thickness of the water film is increased along with the increase of time according to the migration of the water in the soil, the effect of viscosity reduction and desorption is achieved, and the electroosmosis technology is applied. When the existing electroosmosis technology is applied, the surface of a working part is used as a negative electrode, an alternative steel part is used as a positive electrode, soil is used as a conductive medium, and the electroosmosis viscosity reduction system is realized to form a closed loop. However, the electroosmotic effect and efficiency are proportional to the voltage, and the electroosmotic effect is more excellent as the voltage value is higher. In engineering applications, in order to improve the electroosmosis effect and efficiency, a voltage of 220V or more is usually used. Therefore, electroosmosis has serious safety hazard in practical engineering application, especially in engineering machinery.
The invention patent with publication number CN1170991C discloses a bionic surface electroosmosis desorption method, in which positive and negative electrodes are arranged on the surface of the same working component, positive and negative electrode plates are the surfaces of the working component, rubber and plastic materials are filled in the gap between the positive electrode plate and the negative electrode plate to achieve an insulation effect, but in order to reduce working voltage and ensure electroosmosis viscosity reduction effect, the positive and negative electrodes are arranged in an integrated manner, and the viscosity reduction effect is improved by reducing the polar distance.
The patent application of publication No. CN109719089A discloses a device for realizing metal surface viscosity reduction and desorption by using interface electroosmosis pulses, which comprises an electrode plate and a pulse power supply, wherein a direct-current power supply is changed into a pulse power supply, the electroosmosis effect is improved by using a pulse duty ratio principle, and the power supply is still in a positive and negative electrode integrated electroosmosis structure form although the power supply form is changed.
The integrated electroosmosis viscosity-reduction desorption method needs to perform positive electrode hole reserved position treatment on an adhered working part, and on the other hand, an insulation bushing protection measure needs to be performed on a positive electrode to ensure circuit communication.
In the existing electroosmosis technology with separated positive and negative electrodes, the electrode distance is increased due to the separated positive and negative electrodes, the electric field intensity is reduced, the electroosmosis effect is not ideal, and in the existing solution, the voltage increase is the only means for the separated electroosmosis viscosity reduction technology.
