Integrated seal structure for high-temperature wear environment

Abstract

The invention relates to an integrated seal structure for the high-temperature wear environment. The integrated seal structure for the high-temperature wear environment is characterized by comprisingan outer seal, an inner seal, a left support and a right support, wherein the left support and the right support are arranged oppositely; the outer seal is fixed onto the left support; the inner sealis fixed onto the right support; the outer seal is an integrated 'J'-shaped plate; the outer seal and the inner seal form a labyrinth seal; a surfacing wear-resistant layer is arranged on the outer surface of the bending part of the outer seal; and a surfacing wear-resistant layer is arranged on the surface, opposite to the bending part, of the inner seal. According to the integrated seal structure for the high-temperature wear environment provided by the invention, a sealing effect is greatly improved; and through the integrated seal structure, the integrality during the manufacturing of a sealing strip is ensured, the wear resistance of the sealing strip is further ensured, and the problem of seal failure caused by wear of a grate cooler during the use process and edge warping and falling off of a fillet weld wear-resistant plate is solved once for all.

Description

technical field [0001] The invention relates to an integrally formed sealing structure for a high-temperature wear environment. Background technique [0002] At present, the sealing structure of the grate cooler is mostly welding the steel plate and then welding the composite wear-resistant plate on the surface. Under complex working conditions, the maximum temperature of the working environment of the sealing strip can reach 1400°C, and the wear-resistant plate welded by the sealing strip is easy to wear and unsolder during operation, or the wear-resistant plate is warped due to foreign matter stuck in it. , fall off. Once the wear-resistant plate falls off, the gap between the sealing strips cannot be guaranteed at all, so the seal will fail, resulting in a large amount of material leakage and air leakage. If the situation is serious, the equipment will be shut down for maintenance. Contents of the invention [0003] The technical problem to be solved by the present in...
