Description

Technical Field

[0001] The utility model relates to the field of controlling the powder leakage and dust emission in cement plants, and specifically relates to a powder sealing device. Background Art

[0002] Controlling the powder leakage and dust emission in cement plants is a key environmental protection measure and a work to improve production efficiency. To address this issue, cement plants need to take comprehensive measures, including optimizing the grinding process, enhancing the sealing performance of equipment, installing high-efficiency dust removal equipment, conducting regular maintenance and inspections, and implementing strict dust control management systems, etc., to effectively reduce the phenomena of powder leakage during production, transportation, and storage, ensure the safety of the production environment, improve resource utilization rate, and comply with environmental protection regulations at the same time.

[0003] Existing powder materials are usually sealed by the original internal bearings to prevent dust from entering. After being continuously scoured and worn by powder materials for a long time, the original bearing sealing device gradually loses its due protective function and becomes extremely fragile. This continuous physical impact not only accelerates the aging and damage of the sealing parts, but also allows external dust to invade the bearing interior, forming a vicious cycle. Once the dust enters the bearing, it will quickly damage its lubrication system, increase friction and wear, and ultimately cause the bearing to jam and unable to operate normally. More seriously, the sealing failure directly leads to frequent occurrences of powder leakage and dust emission, which not only causes waste of raw materials and environmental pollution, but also seriously threatens the continuous operation and production safety of the production line.

[0004] Therefore, we make improvements and propose a powder sealing device. Content of the Utility Model
