Abstract
The present disclosure relates to systems, devices, and methods for sealing a rotary kiln. In particular, in one or more embodiments, the disclosed systems provide a seal assembly for a high-temperature rotary kiln. For example, in some embodiments, the seal assembly comprises a seal rotor couplable to the high-temperature rotary kiln such that the seal rotor is configured to rotate with the high-temperature rotary kiln. In addition, in some implementations, the seal assembly comprises a seal housing comprising a seal configured to interface with the seal rotor on an external-facing side of the seal rotor such that an internal-facing side of the seal rotor is free of seal component interfaces.
Claims20
A seal assembly for a high-temperature rotary kiln, the seal assembly comprising:
- a seal rotor configured to be coupled to the high-temperature rotary kiln such that the seal rotor rotates with the high-temperature rotary kiln;
- a track roller channel configured to be coupled to the seal rotor;
- and
- a seal housing comprising a seal configured to interface with the seal rotor on an external-facing side of the seal rotor such that an internal-facing side of the seal rotor is free of seal component interfaces.
An assembly comprising:
- a high-temperature rotary kiln comprising a rotary kiln shell forming a chamber;
- a seal rotor coupled to the rotary kiln shell of the high-temperature rotary kiln;
- and
- a seal housing comprising a rope seal configured to interface with the seal rotor on an external-facing side of the seal rotor such that an internal-facing side of the seal rotor is free of seal component interfaces.
An assembly comprising:
- a high-temperature rotary kiln comprising a rotary kiln shell;
- an alignment collar attached to the rotary kiln shell of the high-temperature rotary kiln;
- a seal rotor coupled to the alignment collar such that the seal rotor is configured to rotate with the high-temperature rotary kiln;
- a seal housing comprising a first rope seal and a second rope seal, wherein the first rope seal and the second rope seal each interface with the seal rotor on an external-facing side of the seal rotor such that an internal-facing side of the seal rotor is free of seal component interfaces;
- a fluid port in the seal housing configured to allow a fluid jet to pass through the seal housing onto the seal rotor;
- and
- a material collection bin beneath the seal rotor to capture drop out material from the seal housing and the seal rotor.
