SCREEN UNIT AND SCREEN CHANGER EQUIPPED WITH SAME

摘要

The purpose of the present invention is to provide a screen unit which allows for eliminating rigorous dimension control for preventing the short path phenomenon of material and which has cost advantages, and a screen changer equipped with the same. In the screen unit, a cartridge body (30) includes a hole-formed portion (15) having a plurality of through holes (12) through which the material filtered by a screen pack (14) is allowed to pass; and a contacted outer surface (21) which is provided closer to a base end side than to the hole-formed portion (15) and inclined so as to expand radially outwardly with decreasing distance to the base end. The screen pack (14) has a contacting inner surface (22) which can closely contact with the contacted outer surface (21) of a cartridge (13) when being pressed from a tip end side toward the base end with the hole-formed portion (15) covered from outside.
