Embodiment
Below in conjunction with accompanying drawing the present invention is elaborated:
As shown in the figure, the automatic regulating type dynamic seal apparatus of a kind of upper cover plate angle of sintering machine the beginning and the end sealing comprises upper cover plate 1, expansion bearing bar 2, limit pull rod 3, location sealing supporting rod 4, ash bucket 5, sealing plate 6, forms falling part by oil hydraulic cylinder 7, constant pressure liquid pressing system 8; The upper cover plate 1 that two or more than two is arranged along chassis 9 width directions, when chassis 9 bottom surfaces 10 form arc, polylith upper cover plate 1 can keep and chassis bottom surface 10 still comprehensive engagement, good sealing effect, upper cover plate 1 is supported by expansion bearing bar 2 and location sealing supporting rod 4, flexibly connect by movable axis 11 and fixed support 16 in the middle of the expansion bearing bar 2, expansion bearing bar 2 can rotate around movable axis 11; Expansion bearing bar 2 one ends are equipped with running roller 13, and the other end is connected with the oil hydraulic cylinder 7 of falling part by stay cord, pull bar; Be provided with groove in the middle of the location sealing supporting rod 4 under shed, the groove frame is on the bearing edge 17 of fixed support plate, location sealing supporting rod 4 one ends 18 are inserted in the downward groove that upper cover plate 1 bottom surface has, and the other end is connected with the oil hydraulic cylinder 7 of falling part by stay cord, pull bar;
Roll and contacts in expansion bearing bar 2 running rollers 13 and upper cover plate 1 bottom surface, can relative movement, constitute kinematic pair, and upper cover plate 1 is the fulcrum rotation with location sealing supporting rod 4 then; This has just thoroughly changed between former upper cover plate and two connecting rods all is the mechanism of rotary pair, and upper cover plate 1 changes rotation into by translation, has guaranteed that upper cover plate 1 comprehensively contacts with 10 maintenances of chassis bottom surface, and sealability increases substantially.
Upper cover plate 1 bottom surface is provided with restraining groove, and restraining groove side plate 12 has strip hole 15, and rolling axle 14 both sides are inserted the restraining groove side plate and had in the strip hole 15; Make expansion bearing bar 2 and upper cover plate 1 relative movement within the specific limits, play preventing that upper cover plate 1 from being pushed away the effect of location sealing supporting rod 4 supporting fulcrums by chassis 9 again.
Location sealing supporting rod 4 intermediate groove are used integral plate between location sealing supporting rod contact upper cover plate 1 groove, play the first road seal action;
Be provided with ash bucket 5 between location sealing supporting rod 4 and the bellows 19, dust and bulk cargo can be got rid of from ash bucket 5.With 6 sealings of rigid seal plate, rigid seal plate 6 one ends are suspended on the upper cover plate between ash bucket 5 and the bellows 19, and the other end is overlapped on the riser of bellows 19, forms sliding contact, constitutes the sealing of second diatom contact.The sealing plate 6 of rigidity is made by the higher steel plate of wear-resisting property, realizes that by conducting oneself with dignity the sealing of plate two end lines contact, the good reliability of sealing, its thickness can guarantee that it has long working life, and installation is changed simple and convenient.
Form falling part by oil hydraulic cylinder 7, constant pressure liquid pressing system 8; Constant pressure liquid pressing system 8 makes oil hydraulic cylinder 7 keep constant compression force, will make upper cover plate 1 and chassis bottom surface 10 contact forces constant.When the constant pressure liquid pressing system has been realized the equilibrium of forces of upper cover plate 1 and oil hydraulic cylinder, fixing behind the pressure raising certain value with hydraulic system again, will make upper cover plate 1 and chassis bottom surface 10 contact forces constant.The wearing and tearing on chassis bottom surface 10 and upper cover plate 1 surface can alleviate significantly, and the pressure of lifting constant pressure liquid pressing system repeatedly when safeguarding makes upper cover plate 1 upper and lower motion repeatedly, removes the material extrusion between the upper cover plate 1, recovers its flexibility, and is easy to maintenance simple.Keep certain clearance by the upper cover plate 1 of prior art and chassis bottom surface 10 and become constant force and contact, the sealing passage that leaks out washes away the cover plate upper surface with the material that causes of avoiding leaking out.
