Abstract
Description
Technical Field
[0001] The utility model relates to a moisture-proof interconnecting device for a bag dust collector, belonging to the technical field of dust removal equipment in the metallurgical industry. Background Art
[0002] Bag dust collectors are usually installed on the top of cement silos, slag powder silos, and other ash silos. During the ash-beating process, the cement tank truck uses an air compressor to blast ash into the ash silo. At this time, the silo is under positive pressure. After the dust collector is turned on, the air is filtered and discharged, and the pressure in the silo is restored to balance. During the ash discharge process, the ash-beating port is closed, and the ash silo is discharged through a star-shaped discharger and a speed-regulating screw device. At this time, the silo is under negative pressure. Negative pressure will cause air to flow back from the exhaust port of the dust collector and enter the ash silo through the filter bag of the dust collector, thereby maintaining the pressure balance in the silo. During summer production, the air humidity is high, and the humid air flows into the silo due to negative pressure, causing the filter bags to be soaked and stuck, and the dust collector to operate poorly. The humid air even enters the ash silo through the rupture of the filter bag, causing the powder in the silo to clump, affecting the ash discharge efficiency.
[0003] At present, the commonly used anti-moisture measures for ash silos are mainly to strengthen inspections, keep the dust collector in good working condition, and keep the ash silo unloading smooth through vibration, arch breaking, etc. However, it cannot solve the problem of moisture intrusion from the root.

[0005] The technical solution of the utility model is:
[0006] A moisture-proof interconnecting device for a bag dust collector comprises a natural air duct, a central flap, a connecting air duct, an exhaust passage and an exhaust flap.

The exhaust flap is arranged at the exhaust port of the exhaust passage. A desiccant is arranged in the vent of the natural air duct.
[0007] One side of the central flap is rotatably connected to the connection between the natural air duct and the connecting air duct, and the other side of the central flap is provided with a central flap counterweight.
[0008] The outer contour of the natural wind duct is smaller than the outer contour of the connecting wind duct, and the size of the central flap matches that of the natural wind duct.
