Technical Field

[0001] This application relates to the technical field of kiln discharging, and particularly to a dust-proof structure for a discharging hopper of a kiln. Background Art

[0002] The discharging hopper for a kiln is a device used to discharge materials from the kiln. Generally, materials (such as ores, limestone, coal, etc.) in the kiln need to be discharged after calcination or other treatments, and at this time, the discharging hopper is required to complete this task.

[0003] In the related art, the discharging hopper is usually set with an opening, resulting in a large amount of dust generated when the material enters the discharging hopper. On the one hand, it pollutes the environment around the discharging hopper, and on the other hand, it also harms the physical health of the staff. Utility Model Content

[0004] In order to reduce the pollution of dust to the surrounding environment during discharging and reduce the harm of dust to the physical health of the staff, this application provides a dust-proof structure for a discharging hopper of a kiln, adopting the following technical solutions:
