Description
Technical field
The utility model relates to a kind of sealing device, relates in particular to a kind of combination sealing arrangement of grog kibbler roll housing end plate.
Background technology
In cement production process, grog kibbler roll housing end plate will often bear 150 ℃～500 ℃ high temperature, the sealing means of existing kibbler roll housing end plate top roll axle is generally single felt sealing, along with high temperature chamotte toasts radiation to it, sealing is damaged very soon, causes and scurries ash leakage material, influences sealing property, safeguard for production and brought inconvenience, influence the operation of production line.
The utility model content
The technical problem that the utility model solved is to overcome to scurry problems such as ash leaks material, the seal resistance to elevated temperatures is poor, the life-span is short, reliability is low in the prior art middle shell end plate (the especially housing end plate of grog kibbler roll) easily, provides a kind of good seal performance, filler is high temperature resistant, the life-span is long, the combination sealing arrangement of the kibbler roll housing end plate of simple in structure, housing end plate that reliability is high, easy to maintenance.
For achieving the above object, the present invention has adopted following technical scheme:
A kind of combination sealing arrangement of kibbler roll housing end plate comprises axle sleeve, pressing plate, backing plate, end plate, liner plate, seal stopper ring and filler; It is characterized in that: described end plate is made of last riser and following riser, the spacing that last riser and following riser stagger and set; The following riser that axle sleeve passes end plate is sleeved on the roll shaft, backing plate is Hough type (half type) structure, it is outer and be attached on the outer wall of following riser of end plate that backing plate is enclosed within axle sleeve, leave inner chamber between around backing plate and the axle sleeve, filler is filled in the inner chamber, pressing plate is sleeved on the external diameter of axle sleeve, and pressing plate compresses backing plate and compresses filler simultaneously; The seal stopper ring outer shroud is a U-shaped, and seal stopper ring is sleeved on the roller bearing, and liner plate is fixed on the inwall of riser on the end plate, and one section intercalation of liner plate is in seal stopper ring U-shaped outer shroud simultaneously.
The utility model serves as main sealing with the labyrinth seal that forms between seal stopper ring and the liner plate, and the radial seal of the axial seal of pressing plate and backing plate and filler is auxiliary seal and close-fitting a kind of like this combination sealing arrangement.Problems such as the ash of scurrying that its use has solved the housing end plate leaks material, and the high temperature filler life-span is short, have good seal performance, filler is high temperature resistant, the life-span is long, simple in structure, reliability is high, advantage such as easy to maintenance.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The combination sealing arrangement of kibbler roll housing end plate comprises axle sleeve 1, pressing plate 3, backing plate 5, end plate 6, liner plate 7, seal stopper ring 8 and filler 9; End plate is made of last riser and following riser, the spacing that last riser and following riser stagger and set; The following riser that axle sleeve 1 passes end plate is sleeved on the roll shaft 10, backing plate is Hough type (half type) structure, it is outer and be attached on the outer wall of following riser of end plate that backing plate is enclosed within axle sleeve, leave inner chamber between around backing plate and the axle sleeve, filler 9 is filled in the inner chamber, pressing plate is sleeved on the external diameter of axle sleeve, and pressing plate compresses backing plate and compresses filler simultaneously; The seal stopper ring outer shroud is a U-shaped, and seal stopper ring is sleeved on the roller bearing, and liner plate is fixed on the inwall of riser on the end plate, and one section intercalation of liner plate is in seal stopper ring U-shaped outer shroud simultaneously.
The combination sealing arrangement of housing end plate of the present utility model has adopted combining of three kinds of sealings: the radial seal of the labyrinth seal between seal stopper ring and the housing, the axial seal of pressing plate, backing plate.
In this combination sealing arrangement, implement structure and install as follows: liner plate is fixed on the inwall of last riser of end plate, certain depth in the seal stopper ring of liner plate lower edge embedding simultaneously; Axle sleeve passes the following riser of end plate, and pressing plate is installed on the external diameter circumferencial direction of cover; Backing plate is fastened on by bolt on the outer wall of following riser of end plate, and filler is installed on the external diameter circumferencial direction of cover and is installed in the inner chamber of backing plate, by the jackscrew threaded adjusting on the pressing plate pressing plate is played to filler and compresses or unscrew; Backing plate is a left and right sides Hough type structure, radially links into an integrated entity and is fixed on the housing outer wall by bolt.Set forth three kinds of sealings below respectively:
A. the lower edge of liner plate is embedded in certain depth in the seal stopper ring that has groove, has played labyrinth seal function, and this is the main sealing in the combination sealing arrangement;
B. radially being fastenedly connected of the bolt on the backing plate 4 is integral, and makes filler produce thrust diametrically, plays the radial seal effect.
C. by the adjusting of jackscrew 2, make pressing plate on axis direction, produce thrust, played the axial seal effect.What filler adopted is the material of 600 ℃ of high temperature of two-layer ability.
The utility model is applied in housing end plate (especially grog kibbler roll housing end plate), even under the operating mode of higher temperature, the ash of scurrying that it has equally thoroughly solved housing end plate place leaks material, the short production difficult problem that waits of seal life.Combination sealing has favorable sealing property, filler is high temperature resistant, the life-span is long, simple in structure, reliability is high, advantage such as easy to maintenance.
