Particle crushed material filtering device for biomass particle processing

The utility model belongs to the technical field of biomass particle processing, particularly relates to a crushed particle filtering device for biomass particle processing, and aims to solve the problems that a filtering plate in an existing crushed particle filtering device for biomass particle processing is usually fixed in the device and cannot be detached and replaced, so that the filtering plate is inconvenient to clean, and the working efficiency is high. According to the technical scheme, the filter comprises a machine shell and a filter box, vertical grooves are formed in the inner walls of the left side and the right side of the machine shell, lifting sleeves are installed in the vertical grooves in a sliding mode, and sliding grooves are formed in one sides of the lifting sleeves. The device is reasonable in structural design, up-down reciprocating motion of the filter box is achieved through cooperation of the lifting sleeve and the extension plate, fixed connection of the lifting sleeve and the e
