Positive-pressure drying-resistant sealing module

The utility model discloses a positive pressure drying-resistant module. The device comprises a base, a steel belt circulation sealing mechanism, a driving system, an inner positive pressure protection system and a humidification system, a left fixing base and a right fixing base are installed at the two ends of the base, the steel belt circulation sealing mechanism is installed at the two ends ofthe base, the driving system is installed on the top face of the base, and the positive pressure protection system and the humidification system are installed in the left fixing base. The utility model has the design characteristics that a fully-sealed mechanism is designed; positive pressure slightly larger than atmospheric pressure is filled in the inner cavity; the steel belt is tightly attached to the steel belt sealing plate under the action of internal pressure; a layer of high-abrasion-resistance colloid material is attached to the inner sealing face of the workpiece, the low-frictioneffect is achieved, and th
