Description

Technical Field

[0001] The utility model relates to the technical field of limestone powder elevators, and more specifically, to a desulfurized limestone powder elevator. Background Art

[0002] Desulfurized limestone powder is an industrial product used to remove sulfur dioxide produced in coal combustion and other processes. During the processing of desulfurized limestone powder, the treated limestone powder needs to be transported to the top of a large equipment and put into the equipment for storage or subsequent processing. Usually, an elevator is used to vertically transport the material to the appropriate height before feeding.

[0003] However, in actual use, the feeding port height of some existing elevators is set at the middle of the feeding box. When the height of the material accumulation is lower than the feeding port, the material at the bottom of the elevator feeding box cannot continue to be fed into the large equipment, resulting in part of the material being retained inside the elevator, which reduces the actual feeding amount, thereby affecting the feeding efficiency of the elevator. In addition, the feeding angle of some elevators is mostly fixed, which affects the flexibility and practicality of the elevator. Utility Model Content
