Embodiment Construction

[0027] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0028] refer to figure 1 On the one hand, the present invention provides a sealing assembly, which is used to seal the connecting portion of the first structural member 1 and the second structural member 2 . The connection relationship between the first structural member 1 and the second structural member 2 is that the second structural member 2 rotates relative to the first structural member 1, that is, the first structural member 1 is fixed, and the second structural member 2 rotates around the axis. rotate. In this way, as mentioned in the background art, due to the relative movement of the first structural member 1 and the second structural member 2, there...

Abstract

The invention discloses a sealing assembly, for sealing a connecting part of a first structural member and a second structural member rotating relative to the first structural member. The sealing assembly comprises a sealing sleeve sleeved on the outside of the connecting part, a flexible sealing unit sleeved on the outside of the second structural member, and a spiral pushing unit connected to the outer peripheral wall of the second structure and located in the sealing space enclosed by the sealing sleeve, and used for pushing a material leaked into the sealing sleeve back into the first structural member and/or the second structural member. One end of the sealing sleeve is connected to the first structural member. One end, close to the connecting part, of the flexible sealing unit is connected to the other end of the sealing sleeve, and the other end away from the connecting part is gradually contracted to attach to the outer peripheral wall of the second structural member in the radial direction of the second structural member. The invention also discloses a rotary kiln and a sealing method. The sealing assembly can effectively improve the working environment, prolong the service life and improve the sealing effect.

Description

technical field [0001] The invention relates to the field of rotary kilns, in particular to a sealing assembly, a rotary kiln and a sealing method. Background technique [0002] Rotary kiln is an important equipment in metallurgy, chemical industry, cement and other industries. It can be used in drying, sintering, decomposition, calcination and other processes, and plays a key role in production. The rotary kiln includes a stationary kiln head cover and a kiln tail cover, and a kiln shell that rotates relative to the kiln head cover and the kiln tail cover. Since the rotary kiln shell is rotating, while the kiln head cover and kiln tail cover are fixed, there must be gaps in the connecting parts of the rotary kiln shell and the kiln head cover and kiln tail cover. In order to prevent material leakage or external medium from entering the rotary kiln, the rotary kiln is often equipped with a sealing device. [0003] There are many sealing structures for the existing rotary k...
