Description

Double-mass circular vibrating screen

Technical Field

The utility model relates to a circle shakes and sieves technical field, especially relates to a two plastid circles sieves that shake.

Background

The vibrating screen operates by utilizing reciprocating rotary type vibration generated by vibrator excitation. The upper rotary heavy hammer of the vibrator makes the screen surface generate plane rotary vibration, the lower rotary heavy hammer makes the screen surface generate conical surface rotary vibration, the combined effect of the two rotary heavy hammers makes the screen surface generate complex rotary vibration, and the vibration track of the two rotary heavy hammers is a complex space curve. The projection of the curve on the horizontal plane is a circle, and the projection on the vertical plane is an ellipse, and the amplitude can be changed by adjusting the exciting force of the upper and lower rotary weights. And the curve shape of the motion trail of the screen surface can be changed and the motion trail of the materials on the screen surface can be changed by adjusting the space phase angle of the upper and lower heavy hammers.

At present, the circular vibrating screen is widely applied to a plurality of industries, such as processing aggregate of sand and stone, ore and the like, the screen can be single-layer or multi-layer, and is flexible and wide in application, but under the same amplitude of the current circular vibrating screen body, the power of a motor is higher, and when the circular vibrating screen is used for a long time, the energy consumption is high and energy is not saved.

SUMMERY OF THE UTILITY MODEL

For overcoming the problem that exists among the correlation technique, the embodiment of the utility model provides a two plastid circles sieve that shakes has solved the great energy consumption higher problem of present circle sieve motor power that shakes.

The embodiment of the utility model provides a two plastid circle sieves that shake, shake spring and biography frame including screen frame, unipolar vibration exciter, sieve, tip transmission, motor, biography, the biography is shaken the inside of frame mount and screen frame, the biography is shaken the spring mounting and is being passed in the frame that shakes, and the biography is shaken the spring and is set up in the side of unipolar vibration exciter, and the biography is shaken the spring and is located unipolar vibration exciter and biography and shake the frame joint that shakes with unipolar vibration exciter and biography respectively between the frame, the side of screen frame is provided with the motor, and the motor passes through tip transmission and unipolar vibration exciter fixed connection, the bottom of unipolar vibration exciter is connected with damping spring, and damping spring is connected with.

Furthermore, the number of the vibration transmission springs is not less than twelve, and twelve vibration transmission springs are distributed on the side face of the single-shaft vibration exciter in a surrounding mode.

Further, the screen body is arranged in an inclined manner, and the inclination angle of the screen body is fifteen to thirty degrees.

Further, the bottom of the motor is fixedly connected with a motor support.

The embodiment of the utility model provides a technical scheme has following beneficial effect: the screen frame is the same with the conventional round sieve that shakes, and its first plastid unipolar vibration exciter's amplitude will be less relatively, and then the power of the motor that needs just also is less, just more energy-conserving for under the equal amplitude of screen frame, the more conventional round of motor power shakes the sieve less, long-term use, the energy consumption is low, more energy-conserving.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention as claimed.
