Description

Scraper device of scraper slag conveyer for thermal power plant Technical Field The utility model relates to the technical field of scraper slag conveying machines, in particular to a scraper device of a scraper slag conveying machine for a thermal power plant. Background A scraper slag conveyer belongs to a conveyer for continuously conveying bulk materials by means of a moving scraper chain. In the process of combustion power generation of a thermal power plant, a large amount of slag is generated, so that a scraper slag conveyor is required to be used for transferring the slag. According to the patent number CN208761475U, a buried scraper conveyor is disclosed, which comprises wear-resistant steel plates, wherein a plurality of wear-resistant steel plates are fixed at the bottom in a shell along the length direction, each riding wheel assembly comprises a first shaft seat and a rotating shaft, and the outer walls of the two sides of the shell are symmetrically provided with the first shaft seats. According to the scheme, the service life of the shell can be prolonged in the implementation process, slag leakage caused by abrasion of the bottom of the shell in a short time is avoided, but in the implementation process, the scraping plates are inconvenient to clean, the load of a motor is increased due to slag adhered to the scraping plates, blocking materials are easy to form, and the device is damaged.
