The invention relates to an inflatable sealing structure of a shaft head of a spiral conveyor. The inflatable sealing structure is characterized by comprising a shaft head, a round cover, an air blower and a fixing plate, wherein the fixing plate is fixedly arranged on a machine body, the shaft head is arranged on the fixing plate, the round cover is arranged outside the shaft head, the round cover is arranged on the fixing plate, and the round cover and the fixing plate form a sealing cavity; an air inlet is formed in the round cover, an air inlet pipe communicating with the sealing cavity isarranged on the air inlet, and the air inlet pipe is connected with the air blower through a vent pipe; and a rubber layer is arranged on the contact surface of the round cover and the fixing plate,and the thickness of the rubber layer is 6mm. According to the inflatable sealing structure of the shaft head of the spiral conveyor, the sealing cavity is formed outside the shaft head, the air blower is used for blowing air to the sealing cavity, so that pressure of the sealing cavity is larger than that of a cavity of the conveyor, the pressure difference is formed at the two ends of the shafthead, material leakage is effectively prevented, and a good sealing effect is achieved.
Description
technical field [0001] The invention relates to the technical field of material conveying, in particular to an inflatable sealing structure for a shaft head of a screw conveyor. Background technique [0002] Screw conveyors are used for material transportation and play an important role in mechanized production. The blade drive shaft of the screw conveyor is bent under its own weight and the reaction force of the material, and there will be a deflection angle at the end support, which will cause gaps in the shaft head and cause material leakage. Especially when conveying powdery materials with conveying wind, the sealing requirements of the entire conveying system are higher. At present, only one kind of filler is used to contact and seal the shaft head, the sealing structure is single, the durability is poor, and it needs to be replaced continuously, which increases the amount of maintenance and affects production. Contents of the invention [0003] The object of the pr...
