Screening device for cellulase processing

The utility model discloses a screening device for cellulase processing, and relates to the technical field of screening devices. The device comprises a workbench, the surface of the workbench is fixedly connected with a feeding box, a feeding pipe, a protection box and a motor, the output end of the motor is fixedly connected with a filtering barrel, the surface of the filtering barrel is fixedly connected with a feeding pipe and a cleaning pipe, the surface of the protection box is fixedly connected with a top plate, and the bottom of the top plate is provided with two telescopic mechanisms. According to the utility model, through the arrangement of the telescopic mechanism, the telescopic mechanism is influenced by the top block, so that the telescopic mechanism continuously shrinks and restores, and then the vibration block is driven to frequently knock the filter barrel, so that the filter barrel can vibrate all the time, and blocked impurities and granular cellulase can fall off from filter holes; there
