Good, the insoluble, non-stick of property.Make sealing ring in the presence of a harsh environment, not easy to wear, sealing enhancing, service life improves.
Even if ring wear, make to form gap between kettle wall and sealing ring, the right-hand member internal diameter and vacuum of sealing ring are tubular
Into spring mounting groove, spring left end is arranged in spring mounting groove, and spring right-hand member contacts with seal receptacle, spring sealing ring with it is close
Pressure is formed between envelope seat, at this moment spring pressure can discharge therewith, compress sealing ring and kettle wall left part external diameter in real time, at this moment seal
Gap between circle and kettle wall just disappears.Material would not be entered in seal cavity in rotary course by gap in kettle,
Finally avoid material from being drawn back into secondary batching in the rotten material in the presence of vacuum in cavity in kettle, cause product drying
It is contaminated during dry.
A kind of sealing device for being used to dry kettle of the present utility model, simple in construction, reasonable in design, good airproof performance, is used
Long lifespan, even if drying kettle is because when long-term use causes the sealing ring to wear, spring pressure can discharge therewith, in real time compression
Sealing ring and kettle wall, make it keep sealing in real time, can effectively prevent material from entering sealed chamber, avoid material in drying course
It is contaminated.
