Maintenance-free slag falling pipe compensator

Abstract

The invention relates to a maintenance-free slag falling pipe compensator. The maintenance-free slag falling pipe compensator is arranged between a slag falling pipe and a slag discharging hopper, andcomprises two corrugated pipes which are mutually connected through a middle pipe, connecting pipes connected with the other ends of the corrugated pipes are fixedly connected with the peripheral parts of a top plate and a bottom plate respectively, and then an inner cavity of the compensator is formed. The inner cavity of the compensator is provided with an inner pipe I, an inner pipe II and aninner ring plate, the inner pipe II partially stretches into the inner pipe I, and the inner ring plate is arranged between the inner pipe I and the inner pipe II, and fixedly connected with the innerpipe I, and is in contact with the inner pipe II without being fixed to the inner pipe II; heat preservation materials are arranged in a cavity between the outer walls of the inner pipe I and the inner pipe II and the inner wall of the corrugated pipe, and the slag falling pipe is inserted in the compensator from a center through hole of the top plate, penetrates through the inner pipe I and theinner pipe II, and enters the slag discharging hopper after stretching out of a bottom port of the inner pipe II. According to the maintenance-free slag falling pipe compensator, since the heat preservation materials are arranged in the closed cavity formed by the inner pipe I, the inner ring plate, the inner pipe II, the top plate, the bottom plate and the corrugated pipes, in the using process,damage and leakage can be avoided.

Description

technical field [0001] The invention relates to a pipeline safety device, in particular to a maintenance-free slag fall pipe compensator used for discharging slag from a thermal power plant boiler. Background technique [0002] The slag discharged from the power plant boiler is usually discharged into the slag hopper through the metal slag discharge pipe. When the slag is discharged, the dust will escape from the gap between the slag discharge pipe and the slag discharge hopper, which seriously pollutes the working environment and is not conducive to the health of the operator. healthy. The invention with the application number 201110174512.6 discloses a slag discharge pipe expansion joint, which is arranged between the vertical slag discharge pipe and the slag discharge pipe, including top plate, partition plate, bottom plate, insulation material, bellows, inner pipe and outer pipe. take over. The top plate is installed in series on the outer wall of the slag discharge pi...
