Abstract
The utility model discloses a graphite lubrication sealing device used for rotary kiln. A fixed friction wafer is installed on a radial sealing ring. The radial sealing ring is suspended on a journal through a suspender. Graphite blocks are installed in the holes arranged on the fixed friction wafer. One end of a material return scoop is fixed on a rotary barrel body; the other end is fixed on the fixed friction wafer. Under the effect of a cylinder, the fixed friction wafer is adhered closely on a movable friction wafer. Friction force is generated between the movable friction wafer and the graphite during rotating process, so that graphite powder is gradually distributed between the fixed friction wafer and the movable friction wafer to realize oil-less lubrication.
Description
Affiliated technical field
The utility model relates to a kind of calcining kiln sealing device, is cement industry rotary kiln graphite lubrication sealing device specifically.
Background technology
At present, rotary kiln has graphite block sealing device, flake type sealing device and wearing piece sealing device with sealing device.Graphite block sealing device medi-spring is subject to temperatures involved, follows the string, and causes poorly sealed; The flake type sealing device, though simple in structure, because the unlubricated scale serious wear that causes influences sealing effectiveness; The wearing piece sealing device is generally used lubricating oil (or lubricating grease) wearing piece, the pipeline complexity, and under the higher environment of temperature, lubricating oil (or lubricating grease) easily evaporates and runs off, and is lubricated insufficient, quickens the wearing and tearing of wearing piece, and the waste lubriation material influences environment.
Summary of the invention
In order to overcome the deficiency of existing kiln with sealing device, the utility model provides a kind of rotary kiln graphite lubrication sealing device, and the sealing device can not only play good sealing function, exempts from lubricating oil (or lubricating grease), realize oil-free lubrication, prolong the service life of wearing piece.
The technical scheme that its technical problem that solves the utility model adopts is: an end of feed back spoon is fixed on the rotary cylinder body, and the other end is the dyanainic friction sheet fixedly, is equipped with on the radial seal ring to decide wearing piece and realize suspension by suspension rod and journal stirrup.Deciding perforate on the wearing piece, the graphite block of packing in the hole.Under the effect of cylinder, to decide wearing piece and be adjacent to the dyanainic friction sheet, the dyanainic friction sheet produces friction in rotary course and between the graphite block, and powdered graphite is distributed to move gradually to be decided between the wearing piece, realizes oil-free lubrication.
The beneficial effects of the utility model are, need not oil or the situation of fat under, wearing piece in the sealing device is realized lubricated, simple in structure, effective.

The specific embodiment
In Fig. 1, radial seal ring (10) hangs by suspension rod (1) and journal stirrup (2).One end of feed back spoon (14) is gone up (see figure 2) with bolting in rotary barrel (16), and dyanainic friction sheet (12) is by on the end face that is bolted to feed back spoon (14); Radial seal ring (10) surface is equipped with and is decided wearing piece (11), and packing (13) is equipped with in radial seal ring (10) inside, and packing (13) contacts with fixed cylinder (15) outer surface.Another surface of radial seal ring (10) contacts with the cylinder head of (5) and holds out against, and decides wearing piece (11) and axially is adjacent to dyanainic friction sheet (12).Decide to have the hole on the wearing piece (11), fixed guide seat (9) is arranged outside the hole, graphite block (8) is housed in the guide holder (9), and graphite block (8) contacts (seeing Fig. 3 and Fig. 4) by the gap of deciding the hole on the wearing piece (11) or decide between wearing piece (11) with dyanainic friction sheet (12).Adjustable support frame (7) is housed on the guide holder (9), and adjustable support frame (7) links by bearing pin (6) and depression bar (4), and one of depression bar (4) has supported weight (3), and weight (3) holds out against graphite block (8) by depression bar (4).
Claims (1)
- A kind of rotary kiln graphite lubrication sealing device, by suspension rod, journal stirrup, weight, depression bar, cylinder, bearing pin, adjustable support frame, graphite block, guide holder, radial seal ring, decide wearing piece, dyanainic friction sheet, packing, feed back spoon, fixed cylinder and rotary barrel and form, it is characterized in that: graphite block is housed in the guide holder, graphite block by decide the hole on the wearing piece or decide between wearing piece the gap with the dyanainic friction sheet contact.
