Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon screening, in particular to an activated carbon screening device. Background Art

[0002] Activated carbon is a general term for carbon materials that are made from carbon-containing raw materials such as wood, coal and petroleum coke through pyrolysis and activation. It has a developed pore structure, a large specific surface area, and abundant surface chemical groups, and has a strong specific adsorption capacity. According to the shape of activated carbon, it is usually divided into two categories: powdered and granular; granular activated carbon has cylindrical, spherical, hollow cylindrical and hollow spherical shapes, as well as irregular shaped broken carbon.

[0003] After the activated carbon is produced, it is usually necessary to screen the activated carbon particles of different sizes to distinguish them. For example, a utility model patent with application number CN202320397273.9 discloses an activated carbon screening device, including a screening box, a feed hopper is fixedly arranged on the top of the screening box, a discharge port is arranged on the right side of the screening box, a screening component is arranged inside the screening box, a discharge component is arranged on the right side of the screening box, and an auxiliary component is arranged at the bottom of the screening box to facilitate the screening of activated carbon.

[0004] Although the above activated carbon screening device can grade activated carbon, during the screening process, the activated carbon will be quickly discharged toward the discharge port, and some unscreened materials may be directly discharged, resulting in incomplete screening and subsequent repeated screening. Therefore, it is necessary to provide a new technical solution to overcome the above defects. Utility Model Content
