The invention discloses a novel double-layer ultrasonic vibrating sieve. According to the technical scheme, the novel double-layer ultrasonic vibration sieve comprises a sieve body, a feeding port isformed in the top of the sieve body, an upper sieve plate is arranged below the feeding port, a material return disc is arranged below the upper sieve plate, a lower sieve plate is arranged below thematerial return disc, and an umbrella-shaped cap is arranged below the lower sieve plate; an upper discharging port is formed in one side of a sieve frame corresponding to the upper sieve plate, a lower discharging port is formed in one side of a sieve frame corresponding to the lower sieve plate, and a bottom discharging port is formed in one side of a sieve frame corresponding to the umbrella-shaped cap; and a vibration exciter is installed on the lower portion of the sieve body. The novel double-layer ultrasonic vibrating sieve has the beneficial effects that materials can be sieved quicklyand efficiently, and the sieving effect is high.
