ABSTRACT:
Apparatus for preventing formation of a sediment layer at the bottom of a tank containing a liquid mixture such as crude oil, refinery products and petrochemical products which tends to form a precursor in the form of a thickening precipitation zone above the bottom. The deposit of sediment is prevented by disturbance of the precipitation zone. The disturbance is created in the form of an overall disturbance pattern with local disturbance regions with vibrating bodies such as strings or bells strings excitable to vibrate and immersed in the liquid mixture. Exciting elements including push and pull units cause the strings or bells to vibrate in fundamental and harmonic overtones and deflect components of the mixture as a function of the amplitude of said sound wave components.
