Description
Technical Field
[0001] The utility model relates to the technical field of material screening, in particular to an intelligent, efficient and energy-saving vibrating screen. Background Art
[0002] When screening fine materials, due to the small sieve holes and low sieve plate strength, it is usually necessary to use multiple sieve plates for screening. The strength of the sieve plates decreases from top to bottom, and the coarse particles are discharged from the upper layer to avoid the coarse particles from impacting the fine sieve plates on the lower layer and causing damage to the fine sieve plates. Usually, multiple sieve plates are arranged on a vibrating screen to screen fine materials, such as 3 layers of sieve plates. However, the more sieve plate layers there are, the greater the mass of the vibrating screen body, resulting in an increase in the vibration weight and higher energy consumption. Moreover, the coarse particles in the material cannot be discharged in time, and are always in a vibration state during the screening process, increasing energy consumption. In addition, when screening, coarse particles usually require low frequency and large amplitude, and fine particles require high frequency and small amplitude, so that efficient screening can be achieved.
