Currently inclined screen is generally uniaxial, although the material handling capacity of uniaxial inclined screen is strong, but the existence of screening effect is relatively poor, the amplitude is unstable, loud noise and other shortcomings, can not meet the user's requirements for the use of vibrating screen.
Our purpose in designing a biaxial inclined screen is to design a biaxial inclined screen with good sieving effect and stable amplitude. The technical scheme of the utility model is inclined screen with two shafts, which includes a motor and a screen body. The utility model is characterized in that two shaft eccentric vibrators are installed on the screen body, and a motor matched with the vibrator respectively. The utility model has good screening effect and improves the screening efficiency of the vibrating screen.
I. Structure:
The series of circular vibrating screen is composed of eccentric shaker, screen box, motor, base and supporting device. The side plate of the screen machine is made of high quality steel plate, the side plate and the beam are riveted by ring groove rivet, the structure is strong, the operation is stable, especially suitable for the screening operation of large raw material factory and concentrator Two, the working principle
The series inclined screen adopts double motor drive two shaft vibrator, the motor base adopts elastic support, and through the tooth belt connection to keep the two shafts synchronized, the variation step is synchronous, the vibrator adopts shaft eccentric and eccentric block to adjust the amplitude, the material sieve line length, uniform and smooth vibration, Vibration form approximate circular motion, the screen material on the inclined screen surface by the screen box impulse and production
The continuous throwing motion makes the particles smaller than the sieve pass through the screen when the material meets the screen surface, so as to realize the classification.
Three, screen machine characteristics:
1. Double motors are used for non-gear forced synchronous dual-shaft drive to spread the vibration source area to a greater extent, making the screen body reasonably stressed, which solves the defect that the previously inclined screen body should not be too long or too large due to its own vibration characteristics and concentrated vibration source area.
2. The vibrator adopts eccentric shaft type thin oil lubrication, which further increases the stiffness and strength of the screen body. The new thin oil lubrication seal structure designed by our company can ensure that the vibrator does not leak oil;
3. The inclined screen frame is made of the frame structure beam and side plate with ring groove rivet, which has the advantages of high structural stiffness and low vibration noise;
4. The motor base adopts ROSTA device. When the shaker starts and stops, the device provides great damping to reduce peak deformation and greatly increases the service life of bearings and V-shaped transmission belts.
5. The vibrating screen is not easy to plug, high screening efficiency, large processing capacity and other advantages.
