Material jamming preventing rotary screen

Abstract

The invention provides a material jamming preventing rotary screen. The material jamming preventing rotary screen comprises a shell, a feeding port, a screen opening, a rotary screen drum, vibration-preventing bearings, a transmission shaft, a servo motor, damping washers, a vibration generator, a discharging port, damping cavities and damping springs. The feeding port is formed in the top end of the shell, and the discharging port is formed in the bottom end of the shell. The coaxial transmission shaft is arranged in the shell. The transmission shaft is assembled in the shell through the vibration-preventing bearings, and the end portion of the transmission shaft is fixed to an output shaft of the servo motor through a coupler. The rotary screen drum is fixed to the transmission shaft and can rotate along with rotation of the transmission shaft. The vibration generator is arranged on the rotary screen drum. The damping washers are arranged between the rotary screen drum and the transmission shaft. The damping cavities extending in the radial direction are evenly arranged in the damping washers. Each damping cavity is internally provided with the corresponding damping spring. The material jamming preventing rotary screen has the beneficial effects that material jamming is prevented, and the running stability is high.

Description

technical field [0001] The invention belongs to the technical field of screening devices, and in particular relates to an anti-stuck rotary screen. Background technique [0002] Compound fertilizer materials need to be sieved before processing to sieve out large-sized particles to ensure the quality of fertilizers. When the existing rotary sieve is sieved, it is easy to get stuck, which is equivalent to the sieve aperture. Particles are stuck in the sieve holes, resulting in the inability to sieve out fine materials, which reduces the screening efficiency. At the same time, the noise generated by the sieving operation is large. An anti-stuck rotary screen that can solve these problems needs further research and development. Contents of the invention [0003] The object of the present invention is to provide an anti-jamming rotary screen with simple structure, simple operation, high operation stability and high production efficiency. [0004] The technical solution of the ...
