Described packing holder connects oil piping system and lubrication station by oil pipe; Described oil pipe is fixed on cone cylinder.
Owing to have employed technique scheme, the present invention has following beneficial effect: hermetically-sealed construction of the present invention is for solid particle leakage, Leakage Gas, cylindrical shell circular runout, be provided with end-face friction ring type, packing contact, Reed type three kinds of ingenious combinations of frame for movement respectively, there is the advantages such as air-tightness is good, structure is simple, safe and reliable, the life-span long, applied widely, to reach the object of sealing device long-term safety reliability service.
The present invention adopts spring leaf to compress the version of packing, and spring leaf is with its good flexibility for compensating the circular runout of cylindrical shell, and multiple tracks packing is fixed in holder, and packing and rotating cylinder directly contact to ensure good sealing.
Between multiple tracks packing of the present invention, grease lubricating system is set, at regular time and quantity to the rubbing surface grease up between packing and cylindrical shell, reduces packing wearing and tearing, increase packing service life.
Packing holder of the present invention be weekly some join end to end and be separately fixed at one end of seal steel plate.Be provided with lap between every two pieces packing_seal seat, during work, lap is filled it up with grease to play sealing function.
Packing holder place of the present invention arranges lifting bolt, reeve in suspension ring circle, by steel wire rope tightening force governor motion, regulate the thrust between packing and cylindrical shell, avoid thrust too small causing to have gap between packing and cylindrical shell or thrust is excessive causes packing rapid wear.
Spring leaf skin of the present invention arranges refractory seals fiber cloth, ensures the gas No leakage at the gap place between spring leaf.
Between spring leaf of the present invention and elevated-temperature seal fiber cloth, diaphragm seal is set, avoids the Leakage Gas at the gap place between spring leaf.
The present invention arranges end-face friction ring type contact sealing, and drag ring is pressed on wear-resistant block end face naturally by sliding force, and its Main Function stops the solid particle in kiln in gas, avoids solid particle be mingled with packing rubbing surface and cause the premature failure of packing.
