Zusammenfassung:A positive-pressure sealing device for a material pendulum rotating shaft belongs to the technical field of material pendulum rotating shaft sealing and comprises the material pendulum rotating shaft, a positive-pressure cavity is fixedly arranged on the periphery of the material pendulum rotating shaft, a sealed positive-pressure cavity is formed between the positive-pressure cavity and the material pendulum rotating shaft, a compressed air connector communicated with the positive-pressure cavity is arranged on the positive-pressure cavity, and the compressed air connector is connected with the positive-pressure cavity. The compressed air connector is communicated with a compressed air source, the positive pressure cavity is further provided with an oil nozzle communicated with the positive pressure cavity, and lubricating grease is led into the positive pressure cavity through the oil nozzle. And the outer surface of the material pendulum rotating shaft is sealed by soft sealing which is formed by matching
