Description

Technical Field

[0001] The utility model relates to the technical field of slag removers, in particular to a scraper slag remover. Background Art

[0002] Generally, there are two ways to remove the ash produced by coal-fired boilers, namely periodic slag removal and continuous slag removal. Periodic slag removal is to regularly place the ash produced by the boiler from the slag holding chamber to the ground and transport it away manually or mechanically. Continuous slag removal uses a spiral boiler slag remover or a chain plate slag remover to transport the ash to the ground and then transport it away manually or mechanically. Periodic slag removal is labor-intensive and has a poor working environment, while continuous slag removal generally uses mechanical slag removal.

[0003] As a type of slag remover, the scraper in the scraper slag remover contacts the lower inner wall of the device when in use. As the drive mechanism drives the scraper to move, the moving scraper pushes the ash inside the device to the designated position.
