[0002] A high-level silo is a container or facility used to store bulk materials. It plays an important role in industrial production and material handling, especially in the metallurgy, chemical, building materials and other industries.

[0003] A high-level silo's smoke duct is a piping system typically used to discharge fumes and dust generated within the silo. The storage and handling of bulk materials in a high-level silo may generate a certain amount of smoke, dust, and harmful gases. To ensure a safe working environment and comply with environmental standards, a smoke duct is typically installed to collect and discharge these fumes and gases.

[0004] The existing smoke pipe sealing structure lacks shockproof function. During the material processing process, the high-level silo may experience vibration. For example, when the material flows out of the high-level silo, especially when the flow rate is large, it may cause the silo to vibrate. These vibrations may be transmitted to the smoke pipe, causing the seals at the smoke pipe connection to loosen or be damaged, thereby affecting the sealing performance. Utility Model Content
