The invention relates to the technical field of paper making, and particularly discloses a bamboo pulp washing and scumming device, comprising a filter barrel. A feed inlet and a discharge outlet areformed in the outer wall of the filter barrel, and a filter plate with a filter hole is slidably connected to the inner wall of the filter barrel; a drive unit is fixed to the outer wall of the filterbarrel, and a lead screw is fixed to an output shaft of the drive unit, and penetrates the inner wall of the filter barrel to be in threaded connection with the filter plate; a piston cylinder is fixed to the inner wall of the filter barrel, a vortex tube is fixed to the outer wall of the filter barrel, and a hot gas end of the vortex tube is connected with a hot air tube leading into the filterbarrel. According to the technical scheme, the drive unit is used for driving the lead screw to rotate so as to drive the filter plate to slide in the filter barrel to realize primary pulp washing ofbamboo pulp, while scumming is realized by the filter plate; besides, as hot air generated by the vortex tube can preheat bamboo materials, soaking time is shortened, exhausting of air in bamboo materials is facilitated, and efficiency of boiling in the follow-up process is improved.
