To solve the problems about particle caking and screen blockage in existing step type vibration sieves, the invention provides a multi-level vibration sieve. An inclination groove, supporting columns,a vibration mechanism and a step sieve are included. The inclination groove is connected to the tops of the supporting columns. The step sieve is located in the inclination groove. A liquid guiding cavity is formed between the step sieve and the inclination groove. The step sieve comprises a plurality of sieve plates. The two sides of the sieve plates are connected to the inner walls of the two sides of the inclination groove. The multiple sieve plates are arranged in a stepped manner in the inclination direction of the inclination groove. Each sieve plate comprises an outer frame and a screen located in the middle of the outer frame, wherein corrugated protruding strips are arranged on the surface of the screen and extend in the direction perpendicular to the inclination direction of theinclination groove. According to the provided multi-level vibration sieve, disengaging of large-particle calcium carbonate surface adhering objects is facilitated, screen blockage is avoided, and thescreening efficiency and the product yield are improved.
