Abstract

The invention discloses a filtering and recycling device applied to a PTA packer. The filtering and recycling device comprises a straight pipe section, an air return channel butt joint flange, a buffer bin butt joint flange and an interval type filtering sharp corner structure. The air return channel butt joint flange and the buffer bin butt joint flange are arranged at two ends of the straight pipe section respectively. The interval type filtering sharp corner structure is arranged in the through hole of the straight pipe section and is used for filtering and recovering a powder material withvariable pressure and density. The problem that an air return channel is prone to being blocked in a PTA powder filling process is solved, air return is stable, and performance is reliable.

Description

technical field [0001] The invention belongs to the technical field of powder packaging per ton, and in particular relates to a filter recovery device applied to a PTA baler. Background technique [0002] When filling PTA (Pure Terephthalic Acid, purified terephthalic acid) powder, a large amount of dust will be entrained when the fan returns to remove dust. At the same time, the natural accumulation of powder in the main silo is complex, which will cause the buffer silo during the feeding process. The drastic change of pressure can directly cause the blockage of the return air passage or burst the flexible connection pipe. However, there are many problems in traditional filters or some special filter screens: poor filtration efficiency, low reliability, easy to block materials and difficult to clean, etc. Contents of the invention [0003] The technical solution of the present invention: the embodiment of the present invention provides a filter recovery device applied to...
