Abstract
The utility model relates to a rotary kiln sealing device, in particular to a structure improvement on a rotary kiln labyrinth sealing device. The utility model provides the rotary kiln sealing device for labyrinth sealing, which has good sealing effect and long service life and is used for sealing by adopting water-cooled and macromolecular material oxidation pellets. The rotary kiln sealing device consists of a labyrinth discharge cover and a labyrinth feeding cover. The rotary kiln sealing device is structurally characterized in that: the labyrinth discharge cover is fixedly connected at the discharge hole end of a rotary kiln cylinder through a fixing flange; a sealing material is filled between the labyrinth discharge cover and the rotary kiln cylinder; the labyrinth discharge cover is provided with a water pipe, and the water pipe is fixedly connected with the labyrinth discharge cover through a water jacket; the labyrinth feeding cover is fixedly connected at the feeding hole end of the rotary kiln cylinder through a fixing flange; a sealing material is filled between the labyrinth feeding cover and the rotary kiln cylinder; the labyrinth feeding cover is fixedly connected with a blanking pipe and an air pipe of the rotary kiln; and the sealing materials are the macromolecular material oxidation pellets.
Description
Technical field:
The utility model relates to a kind of seal of rotary kiln device, relates in particular to a kind of architecture advances of rotary kiln labyrinth-type excluder.
Background technology:
To be industries such as metallurgy, chemical industry, cement carry out the capital equipment of heat treated to bulk material to rotary kiln, generally works under negative pressure.At the shell portion of rotary kiln be fixedly coupled and have the slit between the device inevitably, for stop extraneous air to be inhaled in the kiln or in the kiln gas carry material and leak, on the rotary kiln sealing device must be set.The seal of rotary kiln device generally is the hermetically-sealed construction of being made by high temperature resistant, wear-resistant half flexible material or flexible material, can be out of shape with the motion of rotary kiln comprising heat resisting steel flap, carbon sial composite plate, its flexible sealing structure integral body that combines of general steel plate flap, thereby adapt to kiln body deformability, cylindrical shell beat and the off-centre that rotary kiln produces under the high temperature user mode.
Three kinds of the main labyrinthic sealings of seal of rotary kiln device at present, fish scale lamellar seal, graphite grazing, the fish scale lamellar seal: sealing effectiveness is not good, and service life is short, leaks out the increase power consumption in kiln behaviour process easily; Graphite grazing: parts are various cumbersome, heavier during installation, and service life is shorter, influences sealing effectiveness, and maintenance is frequent, so average unit cost is than higher; Labyrinth sealing: be divided into axial labyrinth type, radial labyrinth formula, axially contact, radially contact seal, because there is not friction in its contactless face, and structure is simple relatively, so it is general that it adopts, but because the gap between labyrinth sealing and the kiln cylinder body is bigger, often need to fill some half flexibilities or flexible sealing material and improve its sealing effectiveness, traditional encapsulant has alumina silicate or asbestos, but long term high temperature is very strong to its destructiveness, and it is more serious to cause leaking out, leak material.
The utility model content:
The utility model is exactly at the problems referred to above, and the employing water-cooled of a kind of good sealing effect, long service life and the labyrinth sealed seal of rotary kiln device of macromolecular material acid pellet sealing are provided.
For achieving the above object, the utility model adopts following technical scheme: the utility model is made up of labyrinth type discharging cover and labyrinth type charging cover, its structural feature is labyrinth type discharging cover is fixed in cylinder of rotary kiln by mounting flange a discharge port end, be filled with the sealing material between labyrinth type discharging cover and the cylinder of rotary kiln, labyrinth type discharging cover is provided with water pipe, water pipe is affixed by water jacket and labyrinth type discharging cover, labyrinth type charging cover is fixed in the feed inlet end of cylinder of rotary kiln by mounting flange, be filled with the sealing material between labyrinth type charging cover and the cylinder of rotary kiln, the tremie pipe of labyrinth type charging cover and rotary kiln, airduct is affixed; Described sealing material is the macromolecular material acid pellet.
The beneficial effects of the utility model:
1, good sealing effect: the conventional seals material is alumina silicate or asbestos, and its sealing is poor, and frictional force is big; And seal of rotary kiln device of the present utility model is labyrinth sealing, adopt the sealing of water-cooled and macromolecular material acid pellet, the heat-resisting quantity of macromolecular material acid pellet, burnish resistance are all very good, can adapt to kiln body deformability, cylindrical shell beat and off-centre that rotary kiln produces fully under the high temperature user mode, so the utility model good sealing effect.
2, long service life: conventional seals device self-temperature height, high temperature is destructive strong to the sealing material, so service life is very short; Labyrinth type discharging of the present utility model is covered with water pipe, can cool off labyrinth type discharging cover by recirculated water, thereby reduces because of the temperature height destroys the volatility of macromolecular material acid pellet, so the utility model long service life.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
The utility model is made up of labyrinth type discharging cover 11 and labyrinth type charging cover 4, labyrinth type discharging cover 11 is fixed in discharging opening 10 ends of cylinder of rotary kiln 6 by mounting flange 7, be filled with sealing material 5 between labyrinth type discharging cover 11 and the cylinder of rotary kiln 6, labyrinth type discharging cover 11 is provided with water pipe 9, water pipe 9 is affixed by water jacket 8 and labyrinth type discharging cover 11, labyrinth type charging cover 4 is fixed in charging aperture 3 ends of cylinder of rotary kiln 6 by mounting flange 7, be filled with sealing material 5 between labyrinth type charging cover 4 and the cylinder of rotary kiln 6, the tremie pipe 2 of labyrinth type charging cover 4 and rotary kiln, airduct 1 is affixed; Described sealing material 5 is the macromolecular material acid pellet.
