Shaft sealing cover axial outer end over glaze is equipped with alloy hoop to embedding, and alloy hoop axial outer end face is processed with annular recess;
Seal ring set is placed on rubber mixing machine rotor shaft, and is pressed on alloy hoop axial outer end face; Stud with teflon plunger in seal ring, teflon plunger protrudes from seal ring and alloy hoop and to fit end face, and teflon plunger projection is embedded in the annular recess of alloy hoop;
Seal ring gland axially cover as on the non-rubber mixing machine rotor shaft held of fitting with alloy hoop of seal ring; Seal ring gland circumference is evenly equipped with multiple tapped hole, a corresponding assembling jackscrew in each tapped hole, and jackscrew length is greater than the thickness of seal ring gland;
Spring is arranged between seal ring gland and seal ring, and spring and seal ring gland contact jaw withstand on the jackscrew that stretches out towards seal ring end;
Number of springs equals jackscrew quantity;
Jackscrew is equipped with locking nut;
Seal ring and seal ring gland and rubber mixing machine rotor shaft synchronous axial system assemble;
Adopt the utility model of technique scheme, sealing between alloy hoop with seal ring forms back palace formula by the concavo-convex combination of teflon plunger and annular recess and contacts, sealing axial pressure simultaneously between seal ring and alloy hoop, regulate by the jackscrew on seal ring gland, be adjusted to convenient pressure, by locking nut locking jackscrew and then guarantee constant pressure.
To sum up, the utility model, by novel seal form, improves sealability, and adds working life simultaneously, and seal ring is arranged on the outside of rotor shaft, is convenient to dismounting and changes.
