Description

Technical Field

[0001] This utility model relates to the field of activated carbon production technology, specifically a screening device for activated carbon production. Background Technology

[0002] Activated carbon is prepared from carbon-containing raw materials such as wood, coal, and petroleum coke through pyrolysis and activation. It has a well-developed pore structure, a large specific surface area, and abundant surface chemical groups. It is a carbon material with strong specific adsorption capacity and can effectively adsorb impurities in gases and liquids. In the process of producing activated carbon, it is often necessary to screen it.

[0003] The "Screening Device for Activated Carbon Production" disclosed in application number "202320852351.X" includes a frame, with a first sieve plate and a second sieve plate fixedly connected from top to bottom on the inner side of the frame. A baffle plate is rotatably connected to one end of the frame. A support frame is provided below the frame. A first connecting ear is symmetrically welded to one end of the top of the support frame. A second connecting ear is symmetrically welded to the bottom of the frame at the corresponding position of the first connecting ear. A double-acting cylinder is rotatably connected between the first and second connecting ears. A vertical plate is symmetrically welded to the other end of the top of the support frame. A connecting plate is symmetrically welded to the bottom of the frame at the corresponding position of the vertical plate. The connecting plate is rotatably connected to the vertical plate. It can screen activated carbon particles of different sizes, and the trapped activated carbon particles of different diameters can be easily collected without repeated screening, making the operation very convenient and quick.

The feeding and unloading of activated carbon need to be repeated during the screening process, which is not convenient for continuous screening of activated carbon and will reduce the production efficiency of activated carbon.
