A sealing device for a centrifuge main shaft, including a main shaft, a sheath and a washer installed on the main shaft, a bearing set in a bearing seat on the main shaft, a gland is provided on the end surface of the bearing seat, a sealing sleeve and a spacer are provided on the inner side of the gland, A support ring a and a lip seal ring a and a lip seal ring b fitted on the sheath are provided between the gland and the sealing sleeve; a support ring b and a lip seal ring set on the sheath Lip seal ring c and lip seal ring d on the top; lip seal ring a, lip seal ring b and the sheath form a closed cavity a, lip seal ring b, lip seal ring c and the sheath form a The airtight chamber b, the lip seal ring c, the lip seal ring d and the sheath form the airtight chamber c. In the present invention, three airtight cavities are formed between the sheath and several lip-shaped sealing rings, and gases of different pressures are introduced into the three airtight cavities to effectively sterilize the lip-shaped sealing rings, so that the centrifuge can operate without work in a bacterial environment.
Description
technical field [0001] The invention relates to a centrifuge, in particular to a sealing device for the main shaft of the centrifuge. Background technique [0002] As a kind of solid-liquid separation equipment, centrifuges are widely used in chemical, pharmaceutical and other industries. However, at present, centrifuges are not widely used as solid-liquid separation equipment in aseptic environments in the pharmaceutical or food industries. Centrifuges generally require high-temperature and high-pressure steam for sterilization. As a device separating the centrifugal cavity and the lubrication chamber, the sealing device itself has the problem of pollution. At present, most sealing devices cannot achieve effective self-sterilization, which restricts the centrifuge. Applications in the aseptic industry. Contents of the invention [0003] The purpose of the present invention is to provide a centrifuge main shaft sealing device, which can effectively prevent lubricating oil...
