Description

Technical Field

[0001] The utility model relates to the technical field of screening, in particular to a multi-stage automatic vibrating screen. Background Art

[0002] Vibrating screens are usually used for screening and grading of granular materials. Their working principle is to make the particles on the screen move relative to each other through vibration, so as to achieve separation and classification of particles. Vibrating screens are widely used in many fields, such as chemical industry, food processing, mining, building materials, etc., for screening, grading, and removing impurities of granular materials. It has the characteristics of simple structure, convenient operation, and high efficiency, so it is widely favored.

[0003] Vibrating screens usually vibrate by means of an exciter or a motor-driven vibrating device. These vibrating devices generate periodic vibration forces, which are transmitted to the screen box, causing the screen box and the screen inside to vibrate. This vibration force can cause the material to move relative to the screen, thereby achieving solid-liquid separation operations such as screening and grading. The structure of the vibrating screen is relatively simple, mainly consisting of a screen box, a vibrating device and a screen, and is relatively easy to maintain and clean.

For materials that need to separate multiple particle size ranges at the same time, single-stage screening vibrating screens cannot meet the precise screening requirements, thus affecting the screening accuracy. In order to achieve multi-stage screening, multiple single-stage screening vibrating screens are required, which will take up more production space and resources.
