Example Embodiment
[0014] Such as figure 1 A specific embodiment is shown, which includes a mixing cylinder 6 and a mixing shaft 1. The shaft head of the mixing shaft 1 extends from the mixing cylinder 6 to the outside of the mixing cylinder 6, and the inside of the mixing cylinder 6 is fixed with a static The sealing ring 5 and the static sealing ring 5 are sleeved on the mixing shaft 1. The part of the mixing shaft 1 located inside the static sealing ring 5 is sleeved with a retaining ring 2 and a dynamic sealing ring 4, and the retaining ring 2 is fixed on the mixing shaft 1. The sealing ring 4 and the stirring shaft 1 are connected by a guide flat key 12, and a spring 3 is connected between the movable sealing ring 4 and the retaining ring 2, and the spring 3 expands and contracts in the axial direction of the stirring shaft 1. The outer end surface of the dynamic seal ring 4 is in sealing contact with the inner end surface of the static seal ring 5. The end surfaces of the dynamic sealing r...
