Description

Technical Field

[0001] The present invention relates to the technical field of defrothing machines, and specifically, to a scale bucket type dry slag removal device.

Background Art

[0002] The core equipment of a dry slag removal system is a slag dryer. Currently, the slag dryers of domestic thermal power coal-fired boiler dry slag removal systems mainly include two types: a mesh belt type (also called a steel belt) slag dryer and a scale bucket type slag dryer. The scale bucket type slag dryer has the disadvantage that the manufacturing process of its conveyor belt is complex. The mesh belt type slag dryer has a high failure rate. In a comprehensive comparison, the scale bucket type slag dryer is superior to the mesh belt slag dryer.

[0003] Although the scale bucket type slag dryer has advantages, the manufacturing process of its conveyor belt is complex, and it is easy for materials to accumulate on one side during the conveying process, resulting in a decrease in slag removal efficiency and wear of the device. Therefore, a scale bucket type dry slag removal device has been proposed.
