Description

Triaxial Elliptical Vibrator

technical field

The utility model relates to a material screening device, in particular to a three-axis elliptical vibrator.

Background technique

At present, mine mining is gradually developing towards large-scale and large-scale development. Vibrating screens play a very important role in the mining industry of mines. As the market continues to improve the quality of materials, high-quality materials have gradually become more important. However, screening machines play a pivotal role in high-quality material production systems. Nowadays, the screening efficiency of most vibrating screens in China is relatively low, most of which are between 80% and 85%. The low screening efficiency reduces the purity of materials and reduces the quality of materials.

In the prior art, the three-axis elliptical screen structure adopts the rotation of the eccentric shaft to generate centrifugal force, so that the vibrating screen can vibrate and generate amplitude. However, the existing vibrator has the following disadvantages: ①. Due to the limited centrifugal force generated by the eccentric shaft, it is difficult to adjust the amplitude; The large size of the middle part makes the shape of the vibrator larger, which increases the height of the screen box, which not only increases the vibration quality but also increases the load on the equipment foundation; ④, because different materials need different excitation forces for screening, In order to achieve a good screening effect, the eccentric shaft exciter is difficult to adjust the exciting force, resulting in unsatisfactory screening effect of some materials and low processing capacity.

The traditional three-axis elliptical screen is composed of gears, eccentric shafts, pulleys, oil field parts, etc. The output of the motor is transmitted to the driving shaft through the pulley, and the driving shaft is transmitted to the driven pump through the gears, so that the three shafts rotate together to generate exciting force. The source of the exciting force is generated by the rotation of the eccentric shaft, but the size of the eccentric force cannot be adjusted. Bearing lubrication and gear lubrication use thin oil lubrication in the same oil tank, which makes the area of the oil tank large, the amount of oil used is large, and the problem of oil leakage often occurs .
