The footpath end certain altitude of piece body, can so play sealing strip sealing function, be also beneficial to ensure that blade body is not worn.
Preferably, described baiting structure is arranged on sealing strip pressing plate, described baiting structure is two inclined planes.Under
Structure setting is expected on sealing strip pressing plate, and baiting structure is arranged to inclined plane, and being so advantageous to particle all can equably fall
Enter and pressurizeed into pressurizing chamber, at the same can also ensure that pressurization after blanking when particle do not accumulate, can whole blankings without
It is caught broken or is brought again into closed pressure stabilizing chamber.
Preferably, described sealing strip pressing plate and sealing strip is fixedly connected by connector with blade body.
Preferably, sealing strip is temperature resistant rubber press strip.Sealing strip uses special temperature resistant rubber press strip, ensures to grind during operating
Rubber strip is damaged, blade body will not be hurt, and be convenient for changing.
The beneficial effects of the utility model are：The impeller blade design, blade body design with vane seals split, leaf
The sealing of piece seal and closed pressure stabilizing chamber is dynamic to be coordinated, and when blade is with wheel rotation, abrasion is vane seals, rather than leaf
Piece body, makes blade body not be worn, and vane seals can be changed, easy to operate, and cost is low, can effectively improve blade
Utilization rate, on vane seals set baiting structure both ensure splicing when particle can be efficiently entering pressurizing chamber, also can
Ensure after the pressurizing blanking when particle do not accumulate, can whole blankings without being caught broken or being brought again into closed pressure stabilizing chamber.
