Anti-blocking slag conveyor for thermal power plant boiler

Abstract

The invention discloses an anti-blocking submerged chain conveyor for a thermal power plant boiler, and relates to the field of boiler submerged chain conveyors. The slag conveyor comprises a water seal tank, a slag conveyor body and a boiler, bearings are mounted on the inner wall of the water seal tank, a connecting shaft is connected between the two bearings, a stainless steel frame is mounted on the outer sides of the bearings, the stainless steel frame is wrapped with a filter cover, the bearings can be separated from slag water through the stainless steel frame, and the slag water can be separated through the filter cover; a mounting seat is fixed on the rack, the mounting seat is connected with a scraping plate through a spring, after the slag salvaging machine main body is started, the conveying belt rotates to drive the baffle to move, and when the conveying belt is at the end of the slag salvaging machine main body, the baffle rotates to prevent impurities in slag water from entering the bearing, the bearing is prevented from being blocked, the bearing is protected, and the service life of the bearing is prolonged; the baffle is in contact and friction with the scraper, the special-shaped scraper can scrape slag adhering to the baffle, operation is easy and convenient, and the service life of the slag salvaging machine body is prolonged.

Description

technical field [0001] The invention relates to the field of slag extractors for boilers, in particular to an anti-clogging slag extractor for thermal power plant boilers. Background technique [0002] In the existing thermal power plant, the slag produced in the boiler is discharged into the slag extractor from the bottom, and the water in the slag extractor water tank cools down the temperature of the slag and then uses the chain to transport it to the slag bin. When the air enters the boiler, the bottom of the boiler will be submerged into the tank of the slag extractor, and the water surface of the tank of the slag extractor will form a water seal to isolate the air. [0003] According to the retrieval, the Chinese patent No. CN202020813648.1 discloses a boiler slag remover, which prevents the ash from entering the upper water seal tank by setting the ash baffle, but most of the slag removers are plate conveyors. The bearing of the conveyor needs to be soaked in the sla...
