Self-suspension negative pressure suction type floater separating and removing device

The invention discloses a self-suspension negative pressure suction type floater separating and removing device which comprises a filter cylinder, the symmetrical outer ends of the filter cylinder are fixedly connected with drainage pipes, the other ends of the drainage pipes are fixedly connected with a closed water tank, an air pressure pipe is fixedly connected between one set of drainage pipes and the closed water tank, and a water storage buoyancy adjusting cavity is formed in the filter cylinder. The invention relates to the technical field of sewage treatment. According to the self-suspension negative-pressure suction type floating object separating and removing device, the air content in the cavity is adjusted by controlling the volume of water in the water storage buoyancy adjusting cavity, and by means of the atmospheric pressure principle, the suspension height of the filter cylinder on the water surface can be automatically adjusted, floating objects on the water surface can conveniently enter the
