Description

Technical Field

[0001] The utility model belongs to the technical field of unloading equipment, and in particular relates to a material unloading sealing device. Background Art

[0002] Cyclone separators, pulse dust collectors, etc., perform gas-solid separation under a certain positive or negative pressure. The particles or powders collected in the separation equipment need to be discharged in time, and the process of discharging the materials is the unloading process. During the unloading process, it is necessary to discharge the particles or powders from the equipment while preventing the air inside the equipment from overflowing with the materials when the internal pressure of the equipment is positive, and to prevent the outside air from flowing into the equipment when the equipment is under negative pressure. At present, cyclone separators and pulse dust collectors used for gas-solid separation are usually equipped with fan shut-off fans for unloading. The air-closing effect of the fan shut-off fan depends on the gap between the star-shaped blades and the outer casing, requiring high processing precision and small gaps, but they cannot effectively isolate the gas phase from communicating with the inside and outside of the equipment, and as the gap becomes larger due to wear during use, gas phase leakage will also increase.
