Technical Field

[0001] The utility model relates to the technical field of electrostatic separators, in particular to an electrostatic separator for different materials. Background Art

[0002] The electrostatic separator uses the difference in electrical properties of materials in a high-voltage electric field to achieve the purpose of sorting. When the materials are brought to the high-voltage electric field by the corona electrode through the rotating drum, the materials are subjected to various electrical forces, centrifugal forces, and gravity. Due to the different electrical properties of various materials, the force states are different, making the trajectory of the materials when they fall different, thus achieving the purpose of sorting.

[0003] For electrostatic separators for some materials, filters will be used to collect particles or impurities in the objects to be sorted to prevent them from entering the interior of the separator, thereby protecting the normal operation of the equipment and extending the service life of the equipment. However, some materials may have smaller agglomerated materials when feeding, and the crusher cannot effectively crush the smaller agglomerated materials. These agglomerated materials will be retained on the filter and cannot be effectively cleaned for a long time, which will not only waste materials but also likely clog the filter and affect the normal operation of the separator. Therefore, the present application proposes an electrostatic separator for different materials. Summary of the invention

[0004] The utility model aims to solve the problem of agglomerated materials being retained on a filter screen in the background technology and to provide an electrostatic separator for different materials.

[0034] like Figure 1 and Figure 2As shown, the electrostatic separator also includes a pushing device, which is arranged on the inner wall of the feed hopper 3 and is used for automatically pushing and conveying the agglomerated materials retained on the filter screen 4.
