Solid material radial sealing device

The utility model provides a solid material radial sealing device which is installed between an equipment box body and a rotating shaft, the rotating shaft penetrates through the equipment box body, the rotating shaft and the equipment box body rotate relatively, a gap between the rotating shaft and the equipment box body is a sealing cavity, and the solid material radial sealing device comprises an outer sealing ring and sealing filler. Wherein more than one annular groove is distributed on the inner circle surface of the outer sealing ring, the sealing filler is filled in the annular groove, the thickness of the sealing filler is greater than the depth of the annular groove, and the outer sealing ring is sleeved on the rotating shaft, so that the sealing filler is tightly contacted with the rotating shaft. The sealing device is good in sealing performance, good in deflection resistance, convenient to install and long in service life. 本实用新型提供了一种固体物料径向密封装置，安装于设备箱体与旋转轴之间，旋转轴穿过设备箱体，两者相对旋转且两者之间的间隙为密封腔，所述固体物料径向密封
