I. fish scale seal
fish scale seal is the most popular sealing form at the present stage. Because of its simple installation and maintenance and good sealing performance, it can be used for both rotary kiln head seal and rotary kiln tail seal. It is also widely used in dryer and single cylinder cooler, which is the most common sealing form. Taking the cement instry as an example, the head seal of rotary kiln adopts the fish scale seal, and the proportion of the tail seal using the fish scale seal is also relatively large. Other instries, such as metallurgy, building materials and chemical instry, also use fish scale seal< 2. Cylinder seal
cylinder seal is mainly used in rotary kiln tail seal for procing powder materials, which is widely used in cement instry. Due to its troublesome maintenance in the later stage and certain requirements for external equipment, many kiln tail seals with cylinder seal have been transformed into fish scale seal at present< 3. Graphite block seal
graphite block seal can be used for both kiln end seal and kiln head seal. The old graphite block seal adopts axial seal, which is the same as the cylinder seal. Due to its defects, few units are used now. The new graphite block seal with radial seal will be the future development direction< 4. Labyrinth seal
labyrinth seal is a labyrinth form composed of multiple annular baffles with different diameters. Due to its high requirements for the equipment itself, it is not widely used now. However, the combination of labyrinth seal and fish scale seal and graphite block seal are still used in some enterprises< 5. Flapper seal
flapper seal is an earlier type of seal, which is similar to cylinder seal in that it is radial seal and adopts flapper seal gap. The difference is that flapper seal is generally supported by hammer or spring, cylinder seal is supported by cylinder seat, and flapper seal has been basically eliminated.
