Description

Boiler dross removal mechanism of thermal power plant Technical Field The utility model relates to the technical field of boiler equipment of a thermal power plant, in particular to a slag removing device of a boiler of the thermal power plant. Background The ‌ ‌ ‌ ‌ ‌ ‌ ‌ ‌ ‌ ‌ thermal power plant boiler is energy conversion equipment in three major equipment of a power plant, and is used for converting chemical energy of fuel into heat energy, and utilizing the heat energy to heat water in a boiler to form superheated steam with sufficient quantity and certain quality for a steam turbine. After the boiler burns fuel such as coal, a great amount of slag is generated, and the slag needs to be cleaned and discharged in time so as to ensure the normal operation of the boiler. At present, the existing boiler deslagging device of the thermal power plant generally has the problem of poor suitability, and most of the structural design of the boiler deslagging device is only aimed at a boiler with a specific specification, and the boiler is particularly difficult to adapt to a boiler with a formula. Because the inside length and width size difference of different square boilers is great, traditional dross removal mechanism can't adjust in order to adapt to this kind of dimensional change fast, leads to dross removal mechanism to be difficult to closely laminate with the boiler inner wall, and then influences slagging-off efficiency and effect. In addition, the deslagging mode of the existing deslagging device is single, and only the scraper is usually driven to perform simple up-and-down reciprocating movement in the boiler. When encountering intractable slag, this kind of single slagging-off mode often is difficult to effectively clear away, not only causes the scraper wearing and tearing easily, still probably leads to dross removal mechanism card to be on, reduces the stability and the life of equipment.
