Description

Technical Field

[0001] The utility model relates to the technical field of boiler deslagging, in particular to a deslagging device for the bottom of a boiler in a power plant. Background Art

[0002] Most thermal power unit boilers use dry slag removal. The slag removal process is to open the hydraulic shut-off door at the bottom of the furnace and let the remaining waste from the furnace combustion fall onto the conveyor belt. The conveyor belt slowly runs to let the burned waste slag fall into the slag crusher. The large slag is then crushed by the slag crusher and falls into the hopper. However, slag blocks are easily accumulated on the hydraulic shut-off door at the bottom of the furnace. In order to prevent the slag blocks from affecting normal use, a slag removal device is required to clean the slag blocks.

[0003] A Chinese patent provides a deslagging device for the bottom of a boiler in a thermal power plant, with publication number CN218763455U, which includes a shell, which is the outer shell of the deslagging device; an electric telescopic rod, which is arranged inside the shell; a connecting rod and a connecting ring, wherein the connecting rod is arranged at one end of the electric telescopic rod.

[0004] The above device facilitates the reciprocating movement of the slag removal rod by the forward and backward movement of the connecting ring, thereby facilitating the cleaning of large slag blocks above the hydraulic shut-off door. By inserting the fixing column into the fixing hole, the operator is protected when cleaning large slag blocks above the hydraulic shut-off door, and is prevented from being injured by slag blocks or hot flue gas ejected when the furnace is under positive pressure.

[0005] However, its structure is relatively simple. When there is a lot of slag at the same location, people need to hold it for a long time to clean it, which is labor-intensive. In addition, the waste slag is pushed down by the slag removal rod, and the length of the slag removal rod is fixed, which makes it less flexible to use. Utility Model Content
