Summary of Dry slag extractor:

① Dry slag extractor (hereinafter referred to as Dry slag extractor) is the key of coal-fired boiler dry slag discharge device, it is mainly composed of sheet steel and steel mesh conveyor chain, as a carrier and drawing parts, to realize the ash collection and transportation work. When working, the hydraulic oil cylinder conveyor chain tension, driven by the power drive roller rotation, through the driving roller and conveyor chain by the tension between friction, to drive the operation of the conveyor chain, so as to realize the collection and transportation of ash, fell on the bottom of fine ash by cleaning chain scraper to complete collection and transportation. In the ash transport process, the negative pressure system for boiler air reverse flow, make the ash discharge cooled to appropriate temperature.

Dry slag extractor by the tail, flat, curved section and oblique section, head, platform, hydraulic station, electric control system and other parts;

② The tail as the tensioning part, through two of the hydraulic oil cylinder, respectively the tension of conveyor chain and chain cleaning;

③ Flat section for ash collecting part, through the two boiler ash slag bucket and extrusion machine fall on the conveyor chain, slag by transmission chain to collect, ash conveying;

④ Conveyor chain wire mesh can buffer the impact of the ash fall produced. Curved section for the change to the part of the conveyor, in which transmission chain, cleaning chain change direction;

⑤ Oblique section for ascending part of the ash, clinker in negative pressure under the action of the wind cooling;

⑥ Chance to head for the dry slag line power part and slag notch, which set the two belt reducer motor, drive conveyor chain and cleaning chain respectively. Platform for operation, maintenance and maintenance;

⑦ Power hydraulic station for tensioning oil cylinder;

⑧ The operation of the electronic control system for Dry slag extractor, control system.
