Technical Field

[0001] This utility model relates to the technical field of limestone conveying equipment, specifically a telescopic enclosed atomizing discharge chute. Background Technology

[0002] Limestone raw materials refer to refractory materials with calcium carbonate as the main component. They can be calcined at high temperatures to produce quicklime, which is widely used in many fields.

[0003] A chute is a device used to transport bulk materials, moving them from a high place or one piece of equipment to a low place or another piece of equipment. By adjusting the angle or opening size of the chute, the feeding speed and flow rate of the material can be controlled. It is commonly used in industries such as mining, metallurgy, chemical industry, and building materials.

[0004] During the transfer of limestone raw materials, the limestone is fed along a chute into a loading trolley. However, due to the gap between the chute and the loading trolley and the lack of sealing measures, a large amount of dust escapes during the feeding process, polluting the environment.
