The work presents an innovative design of a vibrating machine for cleaning pollution with a pulsating immersed jet with solid particles and analytically obtained the dependence of the mass productivity of the machine on the design parameters of the machine and the modes of operation of the vibration drive. The research results show that the optimal oscillation frequency of the machine drive lies in the range from 13 to 14 Hz with an amplitude of oscillations of 2 mm and a ratio of the diameter of the nozzle to the diameter of the pulsation chamber of 1:10. The conducted studies of the effectiveness of cleaning showed that mass wear of metal balls and changes in the roughness of the base of the sample are practically not observed due to the occurrence of minor stresses on the surface of the sample elastic character. As a result of the study of the efficiency of cleaning model pollution, it was found that increasing the angle of attack of a pulsating immersed jet with metal balls from 900 to 1250 leads to an increase in the efficiency of cleaning. The analysis of the appearance of the surface of model pollutants confirmed the main theoretical assumptions about the mechanical nature of the interaction of a submerged pulsating jet of liquid with solid particles with pollution and showed the effectiveness of the method of cleaning pollution with a pulsating submerged jet of liquid with solid particles.
