Abstract

The present invention relates to a trommel screen and a waste sorting system including the same. According to the present invention, the trommel screen (100) includes: a front end part (110) formed with a perforated mesh (110a) in the cylindrical shape; a rear end part (120) which is joined with a circular frame (123) to allow a plurality of screening rods (121) to form a cylindrical shape and is joined with the front end part (110); and a mesh clogging prevention means (130) which reciprocates on an upper part of the front end part (110) and sprays gas on the perforated mesh (110a) to prevent the mesh from being clogged.

Description

technical field [0001] The invention relates to a drum screen and a waste sorting system comprising the drum screen. Background technique [0002] Many structures such as bridges, roads, and various buildings created in the process of urbanization and industrialization have deteriorated over time. In particular, recently, reconstruction and redevelopment have been actively carried out in many areas in order to improve the living culture . A lot of construction waste is generated during the demolition or reconstruction and redevelopment of such aging structures. [0003] In the case of direct landfilling of such construction waste, not only is it difficult to secure a landfill site, but it also consumes a lot of landfill costs and has a negative impact on the environment. Therefore, countries have requested various measures for processing construction waste from both aspects of environmental protection and resource recycling, and in the case of Korea, various processing dev...
